Moleculin Announces FDA Filing for Orphan Drug Designation for Glioblastoma Drug

HOUSTON – December 6, 2018 – Moleculin Biotech, Inc., (Nasdaq: MBRX) (“Moleculin” or the “Company”), a clinical stage pharmaceutical company focused on the development of oncology drug candidates, all of which are based on license agreements with The University of Texas System on behalf of the M.D. Anderson Cancer Center, today announced it has filed a request with the U.S. Food and Drug Administration (“FDA”) for Orphan Drug Status for its drug candidate WP1066.

 

“Clinical progress with WP1066 has been encouraging,” commented Walter Klemp, Moleculin’s Chairman and CEO.  “Given its potential to address rare and difficult to treat cancers, including glioblastoma, we believe WP1066 is well positioned to qualify for Orphan Drug Status.”

 

The FDA grants orphan drug designation to drugs and biologics that are intended for the treatment of rare diseases that affect fewer than 200,000 people in the U.S. Orphan drug status is intended to facilitate drug development for rare diseases and may provide several benefits to drug developers, including tax credits for qualified clinical trials costs, exemptions from certain FDA application fees, and seven years of market exclusivity upon regulatory product approval.

Moleculin Announces Breakthrough Discovery for its WP1066

WP1066 shown to counteract resistance to checkpoint blockades

 

HOUSTON – December 4, 2018 – Moleculin Biotech, Inc., (Nasdaq: MBRX) (“Moleculin” or the “Company”), a clinical stage pharmaceutical company focused on the development of oncology drug candidates, all of which are based on license agreements with The University of Texas System on behalf of the M.D. Anderson Cancer Center, today announced that its own sponsored research has now confirmed a recent published study demonstrating the ability of its clinical-stage immuno-stimulating STAT3 inhibitor, WP1066, to inhibit a key immune checkpoint target known as PD-L1.

 

“We have known for some time that WP1066 had the potential to stimulate a natural immune response,” commented Dr. Donald Picker, Moleculin’s Chief Science Officer.  “But, this data suggests that our drug may be capable of having a major impact on the field of checkpoint blockades. With this information combined with findings from other recently published studies demonstrating the impotant role of STAT3 in cancer immunology, we plan to run additional in vitro and in vivo studies, some of which are already underway, with WP1066 in combination with well-known checkpoint inhibitors to gather more data on this response.”

 

Walter Klemp, Moleculin’s Chairman and CEO added, “This potential was initially reported in a 2017 Japanese study (Journal of clinical and experimental hematopathology, Vol. 57 No.1, 21-25, 2017), but we have now been able to confirm this activity with our own sponsored research at MD Anderson.  Also, very recent independent research (Front Pharmacol. 2018 May 22;9:536. doi: 10.3389/fphar.2018.00536. eCollection 2018.) has linked STAT3, HIF1-a and c-Myc (all targets of WP1066) to the mechanism (a ligand known as PD-L1) believed to be largely responsible for resistance to current checkpoint blockade therapies.  We believe this could put WP1066 center-stage in the field of immunotherapy.  It’s potentially a tremendous breakthrough for our company.”

Moleculin Announces New Data Further Supporting Its Lead Drug for Treating Pancreatic Cancer

WP1732 shown to accumulate beneficially in pancreas

 

HOUSTON – November 28, 2018 – Moleculin Biotech, Inc., (Nasdaq: MBRX) (“Moleculin” or the “Company”), a clinical stage pharmaceutical company focused on the development of oncology drug candidates, all of which are based on license agreements with The University of Texas System on behalf of the M.D. Anderson Cancer Center, today announced that data from an independent test in animal models confirmed, as previously believed, that its immuno-stimulating STAT3 inhibitor achieves disproportionately high accumulation in the pancreas.

 

“Our own sponsored research suggested that WP1732 might be an ideal candidate for treating pancreatic cancer,” commented Dr. Donald Picker, Moleculin’s Chief Science Officer.  “Now, we have independent testing with radiolabeled drug confirming this in animal models.  The propensity for such enhanced pancreatic  distribution could be highly beneficial for a new pancreatic cancer drug.”

 

Walter Klemp, Moleculin’s Chairman and CEO added, “Published research shows that the growth and survival of pancreatic cancer requires activated STAT3 (p-STAT3) and our own research suggests that WP1732 may be one of the most effective inhibitors of p-STAT3 that has demonstrated activity in in vivo models.  Confirming the disproportionately high accumumulation of WP1732 in the pancreas puts us one step closer to introducing an entirely new approach to treating pancreatic cancer.  This is very encouraging and confirms the direction that Moleculin has taken with WP1732. We are heavily engaged in preparing the data necessary for an Investigational New Drug (IND) application with the FDA which we are targeted to file in 2019.”

Moleculin Announces New Independent Study Expands Potential Use of Its Pancreatic Drug Candidate WP1122

Documented potential for drug candidate with characteristics like WP1122 to reverse immune suppression

 

HOUSTON – November 8, 2018 – Moleculin Biotech, Inc., (Nasdaq: MBRX) (“Moleculin” or the “Company”), a clinical stage pharmaceutical company focused on the development of oncology drug candidates, all of which are based on license agreements with The University of Texas System on behalf of the M.D. Anderson Cancer Center, today announced that a new mechanism of action may have been uncovered expanding the potential use of its inhibitor of glycolysis, WP1122.

 

A study recently published in the American Cancer Journal of Cancer Research (Am J Cancer Res 2018;8(9):1837-1846) involving researchers at MD Anderson and the Peking University Cancer Hospital & Institute has found that 2-deoxyglucose (2-DG) has the potential to decrease resistance to immune checkpoint blockade therapy in triple-negative breast cancer (TNBC) in a process known as “glycosylation.”

 

“This study provides a strong rationale for targeting glycosylation with 2-DG in order to improve outcomes for TNBC,” commented Dr. Donald Picker, Moleculin’s Chief Science Officer.  “Historically, 2-DG hasn’t been successfully developed into a drug because of its lack of drug-like properties, including a very short half-life.  Fortunately, based on preclinical data, WP1122, a proprietary prodrug of 2-DG, appears to address that problem and significantly increases the circulation time of 2-DG and its ability to reach specific organs harboring tumors, including the pancreas.”

 

Walter Klemp, Moleculin’s Chairman and CEO added, “The timing of this discovery is perfect for us.  We were already pushing forward with IND-enabling preclinical testing of WP1122 for use in brain tumors and pancreatic cancer and now we see a significant expansion of its potential uses.”

Moleculin Announces Significant Milestone Achieved in Glioblastoma Trial

WP1066 demonstrating drug bioavailability in on-going Phase 1 clinical trial

 

HOUSTON – November 1, 2018 – Moleculin Biotech, Inc., (Nasdaq: MBRX) (“Moleculin” or the “Company”), a clinical stage pharmaceutical company focused on the development of oncology drug candidates, all of which are based on license agreements with The University of Texas System on behalf of the M.D. Anderson Cancer Center, today announced positive progress in the Phase 1 clinical trial of its immuno-stimulating STAT3 inhibitor, WP1066, with initial results showing bioavailability of the drug in patients.

 

“Although this data is preliminary, it represents a significant milestone for the development of WP1066,” commented Dr. Donald Picker, Moleculin’s Chief Science Officer.  “In the first two cohorts of the Phase 1 study, we are already seeing measurable levels of the drug in the patient’s plasma resulting from oral administration.  Knowing we can deliver drug this way opens the door for further development and expanded clinical activity.”

 

Walter Klemp, Moleculin’s Chairman and CEO added, “We believe WP1066 is a first-in-class compound capable of stimulating a natural immune response in animal models while directly attacking tumors by modulating transcriptional activity and repressing what we call ‘oncogenic transcription factors.’  Chief among these is STAT3, considered a master regulator of tumor progression.  While activity in animal models has been very promising, one of the goals of this trial was to determine the potential for bioavailability in humans.  The initial positive indications of this clinical trial increase our confidence that WP1066 has the potential to become an important drug in the treatment of certain cancers. The initial demonstration of human bioavilability is an important milestone.”

Moleculin Announces New Data Discovery Confirming Significant Increase in Potential to Starve Cancerous Tumors

Data to be Presented at Neuro-Oncology Annual Scientific Meeting

 

HOUSTON, Oct. 10, 2018- Moleculin Biotech, Inc., (Nasdaq: MBRX) (“Moleculin” or the “Company”), a clinical stage pharmaceutical company focused on the development of oncology drug candidates, all of which are based on license agreements with The University of Texas System on behalf of the M.D. Anderson Cancer Center, today announced that new data relating to its molecule WP1122 will be presented at the upcoming Society for Neuro-Oncology Annual Scientific Meeting.

 

“We continue to make progress in the development of our inhibitor of glycolysis, WP1122,” commented Dr. Donald Picker, Moleculin’s Chief Science Officer.  “We believe that we have discovered new data during our IND-enabling research with animals that confirms a highly beneficial metabolism of WP1122 and  significant organ accumulation of the inhibitor of glycolysis in the brain and also in the pancreas.  This is especially significant because both brain and pancreatic tumors are highly dependent upon glucose for survival and WP1122 appears to have the ability to inhibit glycolysis, the process by which these tumors convert glucose into energy.”

 

Walter Klemp, Moleculin’s Chairman and CEO added, “Metabolic inhibition of tumors is conceptually a very important approach, and we believe we have a clear translational focus. We have been pushing hard to prepare WP1122 for Investigational New Drug (IND) status.  It is encouraging to have discoveries during this process that appear to confirm the initial premise and give us more hope that WP1122 could become an important new way to deal with difficult cancers like glioblastoma and pancreatic cancer.”

 

The Society for Neuro-Oncology is a multidisciplinary organization dedicated to promoting advances in neuro-oncology through research and education.  Now in its twenty fourth year, the Society continues to grow and mature as the premier North American organization for clinicians, basic scientists, nurses and other health care professionals whose focus is central nervous system tumors in children and adults.  This year’s Annual Scientific Meeting will be held November 15 – 18, 2018 at the Marriott Hotel in New Orleans, Louisiana.

Palm Beach, FL – (September 13, 2018) – Biotech and Big Pharma stocks have been performing very well of lat as the SPDR S&P Pharmaceuticals ETF has risen just about 15% since the beginning of 2018, compared with 8.5% gains for the S&P 500, and up 28% since its low in early May.  Small biotech stocks have earned a great deal of attention lately which is well deserved considering the Nasdaq Biotechnology Index has soared around 13.3% higher this year so far.  Increased investment in research and development is fueling advancements for some biotech companies such as solutions for neurodegenerative disease treatments and anticancer therapies. On pace to surpass $700 billion in revenue by 2025 according to Grand View Research, the biotech sector has become one of the most influential and lucrative forces in the medical market. FDA approvals are also pushing growth in this space as leaders aim to release innovative and unique therapies to battle the various types of diseases and conditions..  Active companies in the markets today include:  Moleculin Biotech, Inc. (NASDAQ:MBRX), Nemaura Medical Inc. (NASDAQ:NMRD), ChromaDex Corporation (NASDAQ:CDXC), Bausch Health Companies Inc. (NYSE:BHC) (TSX:BHC.TO), Geron Corporation (NASDAQ:GERN).

 

Moleculin Biotech, Inc. (NASDAQ:MBRX) BREAKING NEWS:  In the ongoing challenge to combat the almost always deadly brain cancers, namely Glioblastoma and melanoma metastasized to the brain, the pharmaceutical company Moleculin Biotechhas initiated a Phase 1 clinical trial of a new first-in-class cancer drug candidate, a small molecule compound discovered by Prof. Waldemar Priebe at  The University of Texas MD Anderson Cancer Center and known as WP1066. The compound has been shown in animal models to both inhibit an important cell signaling protein STAT3 that is involved in cell growth and proliferation and considered critical to tumor development, while also stimulating an immune response.  The first glioblastoma patient has received the initial doses of WP1066, which were apparently well tolerated, in the physician-sponsored IND (investigational new drug) study at MD Anderson Cancer Center.

 

Built from the chemical backbone of the active ingredient in propolis, a natural product of honey bees, WP1066 is the first anticancer agent with drug-like properties that consistently inhibits the activated form of STAT3 within cancer cells, a target that has been long-sought because of its broad range of tumor promoting effects.   Importantly, activated STAT3 supports the survival and proliferation of tumor cells, evasion of the immune response and metastasis to distant organs, as well as angiogenesis (growth of blood vessels) essential for tumor growth.  Activated STAT3 is not only connected with directly supporting tumor activity, but also suppressing the immune system, making this target even more important to cancer therapy.

 

With the support of extensive preclinical studies demonstrating high antitumor activity  and the critically important ability to cross the blood-brain barrier, WP1066 in this Phase 1 clinical trial will focus on treating aggressive brain tumors which all share a grim prognosis. The intent is to eventually treat up to 15 relapsed brain cancer patients over the next six to eight months. Phase 1 clinical trials typically focus on exploring safe and well tolerated doses, as well as evaluating initial signals of effectiveness. Each treatment is completed over three weeks.

 

“Treating the first brain tumor patient with WP1066 is the start of a very exciting and encouraging program for doctors treating the worst types of brain cancers. There has been very little progress in recent years toward improved therapies for glioblastoma and other aggressive primary or metastatic brain tumors.  WP1066 has shown extremely promising results based on animal studies where we have seen inhibition of tumor growth and improvements in survival,” said Dr. Sandra Silberman, a world-renowned oncologist and Moleculin’s Chief Medical Officer. “This is based on the fact that although STAT3 has long been identified as an important target for treating tumors, for years most efforts have focused on attempts to indirectly inhibit STAT3 from upstream signaling, not from within the cancer cell itself.  WP1066 appears to be unique in its ability in vitro and in animal models to consistently and directly inhibit the activated form of STAT3 and produce significant anticancer effects, including tumor growth inhibition and increased life span of treated animals.”

 

“This represents a major milestone for Moleculin,” commented Walter Klemp, Chairman and CEO.  “There has been tremendous enthusiasm within the oncology community for targeting STAT3, a key molecular hub of multiple pathways promoting tumor growth. Although the industry has been struggling to find a way to target STAT3, we at Moleculin believe that most of these efforts have been mechanistically misguided and ended in failure because their approach would ultimately be ineffective at adequately blocking the activation of STAT3 and lack the necessary drug-like properties to succeed.  The opportunity to test a unique STAT3 therapy in these patients is significant in supporting Moleculin’s mission to provide benefit for those who need new and better treatments.”  Read this and more news for Moleculin Biotech at:  http://www.marketnewsupdates.com/news/mbrx.html

MBRX - Developing Cancer Treatment Trials Positive Indication for Biotech Market

Palm Beach, FL – (June 12, 2018) – Clinical trial data is an important catalyst as well as trial results or any positive updates on the clinical studies are often received well these days in the pharma and biotech market. The industry as whole has bounced back in the past month as it rose 6.8%, better than the S&P 500’s increase of 2.9% making it one of the best-performing industries in the U.S. stock market. On the bright side of things, indications are the demand for drugs is rising worldwide due to increasing ailing and elderly population, frequent approval of new drugs as well as line extensions of already marketed drugs and increased healthcare spending. In addition another positive indication for the biotech industry is the U.S. Food and Drug Administration is taking steps to streamline the approval process for cancer drugs, reviewing clinical trial data up front to make sure applications companies submit are complete. Active companies in the markets today include: Moleculin Biotech, Inc. (NASDAQ:MBRX), Aptose Biosciences Inc. (NASDAQ:APTO), Cardiome Pharma Corp. (NASDAQ:CORV), Pfizer Inc. (NYSE:PFE), Endocyte Inc. (NASDAQ:ECYT).

 

Moleculin Biotech, Inc. (NASDAQ:MBRX) BREAKING NEWS: Moleculin Biotech, a clinical stage pharmaceutical company focused on the development of oncology drug candidates, all of which are based on license agreements with The University of Texas System on behalf of the M.D. Anderson Cancer Center, today announced that it has entered into an agreement with the Jagiellonian University in Krakow, Poland, for the development of its STAT3 inhibitor, WP1732, for the treatment of ocular tumors.

 

“Today there are very limited options for the treatment of ocular tumors,” commented Walter Klemp, Chairman and CEO of Moleculin. “And, these tumors are believed to involve a significant upregulation of the activated form of STAT3. It is important to note that, in addition to the ability of WP1732 to inhibit the proliferation and survival of cancer cells in preclinical studies, as STAT3 inhibitor, it is designed to potently block cancer stem cells and induce immune system function to overcome tumor-induced immune tolerance. This could make WP1732 an ideal candidate for targeting these unique and highly metastatic tumors.”

 

Mr. Klemp continued: “we remain committed to targeting accelerated approval pathways for WP1732 by focusing on significant unmet needs. This includes niche indications like ocular tumors and AML, as well as high-profile indications like pancreatic cancer.” Read this and more news for Moleculin Biotech at: http://www.marketnewsupdates.com/news/mbrx.html

The first publication, entitled “APTO-253 stabilizes G-quadruplex DNA, inhibits MYC expression and induces DNA damage in acute myeloid leukemia cells,” demonstrates that the APTO-253 small molecule anticancer agent inhibits expression of the MYC oncogene and depletes cells of the MYC protein, triggers the DNA repair and stress response pathways, and promotes programmed cell death (apoptosis) in acute myeloid leukemia (AML) cell lines and fresh bone marrow samples derived from patients with AML and other hematologic malignancies that often depend on MYC upregulation.

 

Cardiome Pharma Corp. (NASDAQ:CORV) closed up 48.08% on Monday at $3.08 trading oved 5.7 million shares by the market The company also announced that it has received a response from the U.S. Food and Drug Administration (FDA) regarding the regulatory path forward in the US for BRINAVESS® (vernakalant hydrochloride, IV), Correvio’s antiarrhythmic drug for the rapid conversion of recent onset atrial fibrillation (AF). In its written reply, the FDA informed Correvio that it would be permissible to resubmit the BRINAVESS New Drug Application (NDA) and agreed that the Company may schedule a Pre-NDA meeting. Correvio currently expects that the Pre-NDA meeting with the FDA will take place in the fourth quarter of 2018. “In our most recent communication with the FDA, we asked the Agency if the Division of Cardiovascular and Renal Products would be willing to meet to discuss a regulatory path forward for Brinavess,” said William Hunter, MD, CEO and President of Correvio. “We are pleased that the Agency has agreed to discuss Brinavess in a pre-NDA meeting, which we will seek to have in the fourth quarter.”

 

Pfizer Inc. (NYSE:PFE) recently announced that the U.S. Food and Drug Administration accepted for filing and granted Priority Review designation to the company’s New Drug Application for talazoparib. The submission is based on results from the EMBRACA trial, which evaluated talazoparib versus chemotherapy in patients with germline (inherited) BRCA-mutated (gBRCAm), HER2-negative locally advanced or metastatic breast cancer (MBC). Talazoparib is an investigational, once-daily, oral poly ADP ribose polymerase (PARP) inhibitor. The European Medicines Agency has also accepted the Marketing Authorization Application for talazoparib in this patient population. “Women with a hereditary BRCA mutation are typically diagnosed with breast cancer at a younger age than the overall breast cancer population and have limited treatment options when they develop advanced disease,” said Mace Rothenberg, M.D., chief development officer, Oncology, Pfizer Global Product Development.

 

Endocyte Inc. (NASDAQ:ECYT) last week announced the enrollment of the first patient in its global phase 3 VISION trial of 177Lu-PSMA-617 in prostate cancer by Dr. Luke Nordquist at Urology Cancer Center in Omaha, NE, a member of Precision Cancer Research.

MBRX News - Moleculin Announces Significant Discovery with Potential to Treat Pancreatic Cancer

Metabolic Inhibitor Shows Greater Ability to Kill Pancreatic Cancer Cell Lines – HOUSTON, TX – (https://www.financialnewsmedia.com News Alert) – Moleculin Biotech, Inc., (NASDAQ: MBRX) (“Moleculin” or the “Company”), a preclinical pharmaceutical company focused on the development of anti-cancer drug candidates, some of which are based on license agreements with The University of Texas System on behalf of the M.D. Anderson Cancer Center, today announced the discovery of a metabolic inhibitor with the potential to treat pancreatic cancer.

 

“We’ve received a lot of attention from the scientific community for our glucose decoy technology (WP1122 Portfolio, Moleculin Presents Preclinical Data of Novel Inhibitor of Glycolysis at 28th EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics, December 13, 2016) as a potential means to starve tumors to death by exploiting their hyper-dependence on glycolysis for energy production,” commented Walter Klemp, Chairman and CEO of Moleculin, “and now we have identified possible new properties of our compound WP1234, a modification to WP1122. In pre-clinical testing, WP1234 has shown improved drug characteristics when compared with WP1122 and a 20 to 50-fold greater ability to kill pancreatic cancer cell lines when compared with traditional inhibitors of glycolysis. We know that pancreatic cancer thrives even in a reduced oxygen environment, which indicates it may be highly dependent on glycolysis to survive. This discovery now makes WP1234 a promising drug candidate to be studied for the treatment of pancreatic cancer.” Read this and more news for Moleculin Biotech at http://financialnewsmedia.com/profiles/mbrx.html

 

Mr. Klemp continued: “Pancreatic cancer is still considered largely untreatable, so even modest gains in treating this disease could represent a significant clinical benefit. WP1234 improves on known inhibitors for glycolysis by increasing drug circulation time, which should increase the potential for drug uptake by and destruction of tumor cells. We are excited about the potential to pursue development opportunities with WP1234 for the treatment of pancreatic cancer. We are also pleased to report that this discovery was the direct result of our ongoing collaboration with M.D. Anderson Cancer Center and the science team there will be presenting detailed findings to the scientific community in the near future.”

About Moleculin Biotech

Moleculin Biotech, Inc. is a clinical stage pharmaceutical company focused on the development of oncology drug candidates, some of which are based on discoveries made at M.D. Anderson Cancer Center. Our clinical stage drugs are Annamycin, an anthracycline designed to avoid multidrug resistance mechanisms with little to no cardiotoxicity being studied for the treatment of relapsed or refractory acute myeloid leukemia, more commonly referred to as AML, and WP1066, an immuno-stimulating STAT3 inhibitor targeting brain tumors, pancreatic cancer and AML. We are also engaged in preclinical development of additional drug candidates, including additional STAT3 inhibitors and compounds targeting the metabolism of tumors.

 

Our lead product candidate is Annamycin, a Phase II clinical stage anthracycline for the treatment of relapsed or refractory acute myeloid leukemia, more commonly referred to as AML.

 

Unlike current therapies that risk cardiotoxicity and can have their effectiveness limited due to multidrug resistance, Annamycin appears capable of avoiding both of these problems and has already demonstrated the ability to save lives in clinic.  We are now preparing to seek accelerated approval for this game-changing drug.

 

Annamycin

annamycinAnnamycin is an anthracycline intended for the treatment of relapsed or refractory AML. The therapy of combining two chemotherapeutic drugs, which always includes an anthracycline, in inducing a remission of leukemic cells (called “induction therapy”) has not improved since it was first used in the 1970s and we estimate that this induction therapy has the same cure rate of about 20% as at that time. Currently, the only viable long term option for acute leukemia patients is a bone marrow transplant, which is successful in a significant number of patients. However, in order to qualify for a bone marrow transplant, patients must first undergo induction therapy.

 

One of the leading anthracyclines used for induction therapy in acute leukemia patients is doxorubicin, which has reported over $700 million in annual revenues. Despite the importance and success of approved anthracyclines like doxorubicin, they are all unfortunately cardiotoxic, which can result in damage to the heart and limit the dosage amount that may be administered to patients. Additionally, the tumor cells being treated often have or develop resistance to the first line anthracycline, often through what is called “multidrug resistance” making them capable of purging themselves of the current anthracyclines and limiting the effectiveness of the therapy. Consequently, there remains no effective therapy for these patients and most will succumb quickly to their leukemia. This is where we believe Annamycin can be a complete game-changer.

 

Annamycin is a unique liposome formulated anthracycline (also referred to in literature as “L-Annamycin”) that has been designed to eliminate cardiotoxicity and avoid the multidrug resistance mechanisms that often defeat current anthracyclines. In animal models designed to test for cardiotoxicity, Annamycin as shown to be non-cardiotoxic and in human clinical trials focused on leukemia, it showed fewer dose-limiting toxicities than are normally experienced with doxorubicin (one of the leading first-line anthracyclines used for induction therapy).

 

Annamycin demonstrated efficacy in 8 of 16 patients in a Phase I study in adult relapsed or refractory AML patients, with 6 of 14 patients completely clearing leukemic blasts. A 30 patient dose-ranging Phase I/II study in acute lymphocytic leukemia demonstrated a similar efficacy profile, with 3 of 8 patients treated with the maximum tolerable dose clearing their leukemic blasts to a level sufficient to qualify for a bone marrow transplant. One of these patients went on to receive a successful curative bone marrow transplant.

 

We believe Annamycin is better than the currently approved induction therapy drugs in four key ways: (i) it has demonstrated clinical activity in a patient population for whom there are currently no effective therapies, (ii) it appears to be capable of avoiding the “multi-drug resistance” mechanisms that often limit the effectiveness of currently approved anthracyclines; (iii) it has been shown to be non-cardiotoxic in animal models, when compared with doxorubicin; and (iv) in laboratory studies using AML cell lines, it has been shown to be more potent than the leading approved drug.

 

Based on initial conversations with the FDA, and because of this serious unmet medical need, we believe Annamycin may qualify for for accelerated approval. We also believe Annamycin may qualify for Orphan Drug status, which could entitle us to market exclusivity of up to 7 and 10 years from the date of approval of a New Drug Application (NDA) and Marketing Authorization (MA), in the US and the European Union (EU), respectively.

 

WP1066

Cell Signaling And Oncogenic Transcription Factors

 

Cellular biology depends upon signaling mechanisms to regulate functions such as cell growth, death and adaptation. Signal “transduction” is such a mechanism that converts an upstream stimulus to a cell into a specific cellular response. Signal transduction starts with a signal to a receptor or via a compound capable of passing through the cell membrane and ends with a change in cell function.  The end result of this signal is often the activation of “transcription”, whereby genetic information is expressed and, in the case of oncogenic transcription, disease processes are initiated or maintained.

 

Receptors span the cell membrane, with part of the receptor outside and part inside the cell.  See diagram below. When a chemical signal represented by a specific protein binds to the outer portion of the receptor, it conveys another signal inside the cell.  Often there is a cascade of signals within the cell, wherein an upstream inducer starts a chain of events that resembles a domino effect.  Collectively, this sequence is referred to as a “signaling pathway.” Eventually, the signal creates a change in the cell function by changing the expression of specific genes and production of specific proteins within the cell, and again, in the case of tumor development, such expression results in unwanted inflammatory and proliferative processes.

 

Importantly, while normal healthy cell function relies on signaling mechanisms, diseases are capable of co-opting these mechanisms with negative consequences.  Proliferative and inflammatory diseases depend upon signaling pathways that are responsible for coordinating functions such as cell growth, survival and cell differentiation.  A particular class of proteins referred to as Signal Transducers and Activators of Transcription (such proteins are “STATs”) plays an important role in regulating the process of disease cell survival and proliferation, angiogenesis[1] and immune system function and is persistently activated in a large number of human inflammatory processes and in hyper-proliferating diseases.  Because certain of these proteins are known to be co-opted by tumor cells, we refer to them as “oncogenic transcription factors,”  of which certain STATs are a subset.

 

stat

 

Some STATs, such as STAT3, can be activated by any one of many different upstream inducers, making them very difficult to target by blocking just one or more of these upstream inducers. We believe that blocking a targeted STAT directly rather than via its multiple upstream inducers should result in greater efficacy with lower toxicity.

 

In the diagram shown here, any one of many different pathways (some of which are shown here as Growth Factor Receptors, Cytokine Receptors and Non-Receptor Tyrosine Kinases) triggers the activation of STAT3 proteins in a process called “phosphorylation”.  In this process, phosphates attach to corresponding receptors on STAT3 and the two phosphorylated STAT3 (“p-STAT3”) proteins bind together in a pair referred to as a “dimer”.  Once the dimer is formed, it enters the cell nucleus and triggers gene transcription.   Conversely, if we prevent the dimer from forming (i.e., by blocking phosphorylation), we can prevent the triggering of unwanted gene transcription and effectively inhibit the disease process.

 

The upstream effectors shown in this diagram (SRC, JAK and ABL[2]) are just some of those capable of activating STAT3 once they themselves are activated by a variety of signal compounds.  The complexity and diversity of pathways capable of activating STAT3 makes it very difficult to develop safe and effective drugs that attempt to target the upstream effectors.

 

STAT3

 

Published research has identified STAT3 as a master regulator of a wide range of tumors and clearly links STAT3 activation with the progression of these tumors.  For this reason, it is believed that inhibiting the activation of STAT3 should be an effective way to reduce or eliminate the progression of these diseases.

 

Many research efforts have been directed toward development of specific methods to control activation of STAT3, but most have focused on targeting the upstream effectors of these pathways like growth factors, cytokines, and specific kinases including Janus kinases (JAKs). However, we believe that the multifactorial nature of the activation of STAT3 limits the effectiveness of such upstream approaches. Since the activity of p-STAT3 is a final and determinative step in triggering unwanted transcription, we believe it is preferable to inhibit p-STAT3 more directly and independently from upstream effectors.

 

2015-11-21_1147

 

We believe the WP1066 Portfolio represents a novel class of agents capable of hitting multiple targets, including p-STAT3, regardless of their upstream method of activation. By inhibiting the presence of p-STAT3, WP1066 directly attacks tumor cells, as has been demonstrated in numerous preclinical tests involving a wide range of tumor cells. We believe the effectiveness of WP1066 is not only the result of attacking tumors directly, but also indirectly by stimulating the immune system, increasing the patient’s natural ability to fight off tumor development. STAT1 is believed to stimulate T-cell activity and thereby the immune system responsible for fighting tumors. WP1066 has been shown to increase the activity of STAT1 at the same time it inhibits the activity of p-STAT3. We believe this dual activity makes WP1066 a uniquely promising anticancer drug candidate.

 

We believe the combination of the direct and indirect effects of WP1066 are to be credited with significant tumor suppression and increased survival in a number of in vivo cancer models. Below is one example showing a dramatic increase in survival by treating mice with metastatic melanoma with WP1066.

 

In Vivo Activity

 

In experimental biology, in vitro  (Latin for “in glass”) studies are those that are conducted using components of an organism that have been isolated from their usual biological surroundings in order to permit a more detailed or more convenient analysis than can be done with whole organisms. Colloquially, these experiments are commonly called “test tube experiments”.  In contrast, studies that are conducted with living organisms in their normal intact state are referred to as in vivo (Latin for “within the living”). We have shown in vivo that WP1066 inhibits tumor growth and blocks angiogenesis.  As well, we have shown in numerous mouse tumor models that WP1066 dramatically increases survival.

 

In vivo activity has been confirmed in a wide range of tumors, including metastatic melanoma, glioblastoma, head and neck tumors, bladder cancer, renal cancer and pancreatic cancer.

 

WP1122

Metabolic Inhibitors

 

MBI is engaged in developing new drugs to exploit the metabolic differences between tumor cells and normal cells. MBI’s lead compound is targeted specifically for metabolically active brain cancers, taking advantage of the differential utilization of glucose by cancerous tissue versus normal brain tissue. MBI believes that targeting this difference in metabolism is the key technology making its product competitive and applicable to many other cancers.

 

Our current lead metabolism candidates have shown activity against brain tumor cell lines in in vitro testing and, more importantly, in an orthotopic brain tumor (implanted in the brain) animal model. One candidate has been shown to outperform Schering-Plough’s Temodar®, the frontline FDA approved drug, which is considered the standard of care for the treatment of brain tumors. The market for Temodar® has reached nearly $1 billion in annual revenue. We believe that WP1122 and similar compounds address a significant unmet need in the treatment of brain tumors and should be applicable to other difficult-to-treat, glucose dependent tumors, such as pancreatic cancer.

 

The same principle that drives tumor cells to over-consume glucose allows PET scanning to highlight the size and location of tumors by imaging radiolabeled glucose decoys that are taken up by tumor cells in substantially higher concentrations than normal cells.  PET scanning is less effective in brain scans because such decoys have difficulty crossing the blood brain barrier.  For this reason, our compounds may also lead to a significant improvement in diagnostic imaging of the brain.

 

Need For Improved Brain Cancer Drugs

 

MBI’s technology has the potential to target a wide variety of solid tumors, which eventually become resistant to all treatments, and thereby provide a large and important opportunity for novel drugs. Notwithstanding this potential, MBI is focused on the treatment of central nervous system malignancies and especially glioblastoma.  Although less prevalent than some larger categories of solid tumors, cancers of the central nervous system are particularly aggressive and resistant to treatment. The prognosis for such patients can be particularly grim and the treatment options available to their physicians are among the most limited of any cancer.

 

The National Cancer Institute has estimated 22,850 new cases of brain and other nervous system cancers will occur in the United States in 2015, resulting in 15,320 deaths.  Despite the severity and poor prognosis of these tumors, there are few FDA-approved drugs on the market. The market leader is temozolomide (Temodar®, Merck), which is prescribed for glioblastoma and refractory anaplastic astrocytoma. Notwithstanding the rare nature of brain cancer, Merck (who acquired Schering-Plough, the maker of Temodar) reported sales of $882 million worth of the drug in 2012.  The patent for Temodar expired August 31, 2013.

 

The market for drugs to treat brain cancer is clearly open for new entries. MBI is developing a drug that attacks a different target than Temodar® and has shown efficacy in animal models. MBI’s products could be stand-alone treatments or provided in combination with other drugs, surgery and radiotherapy.

 

mriTargeting the Metabolism of Cancer

 

As far back as 1930, science recognized that many cancer cells have a unique metabolism, distinct from that of normal cells.  Dubbed the “Warburg Effect” by its discoverer, “tumors rely preferentially on glycolysis for the metabolism of glucose, even in the presence of abundant oxygen for energy (adenosine triphosphate (ATP)) production.”  This alternative form of energy production makes cancer cells as much as 17 times more dependent on glucose than normal cells.

 

The fundamental mechanism for imaging actively growing tumors using positron emission tomography (PET scans) is the Warburg Effect.  As shown in these images at the left, a radio labeled glucose decoy called F18DG accumulates disproportionately in tumors because of their dramatically increased rate of glucose uptake and accumulation.

 

For decades, researchers have theorized that if you could block a tumor’s access to glucose, you could essentially starve the tumor out of existence. Previous attempts at targeting the metabolism of tumor cells have failed due to the rapid metabolism and short half-life (minutes) of the drugs being investigated. Efforts to target tumor metabolism in the brain were further thwarted by the inability to get glycolytic inhibitors into the brain in sufficient (therapeutic) amounts due to the presence of what is called the “blood brain barrier”.

 

We believe WP1122 and similar molecules provide the potential to develop a technology platform for enabling increased cellular uptake, increased drug half-life and, importantly, an increased ability to cross the blood brain barrier, enabling greater uptake in the brain. Our approach was inspired by the same principle that distinguishes morphine from heroin. Heroin is chemically the diacetyl ester of morphine. While morphine has a limited ability to cross the blood brain barrier (making it a good candidate for pain killing without impairing mental function), its diacetyl form, heroin, has the ability to accumulate in the brain by 10 to 100 fold more than morphine. Once across the blood brain barrier, the acetyl groups shown in this chemical diagram are cleaved off by natural enzyme esterases, leaving pure morphine to accumulate in the brain.

 

wp1122

 

MBI’s scientific founder, Dr. Waldemar Priebe, invented the diacetyl ester of a glucose decoy known as “2-DG”, which became WP1122.  We believe based on pre-clinical testing that, just like heroin, WP1122 crosses the blood brain barrier where its acetyl groups are cleaved off, allowing the resulting 2-DG to accumulate in the brain at a much higher rate than free 2-DG can do by itself.

 

Adding to the difficulty in getting free 2-DG across the blood brain barrier in therapeutic quantities, is the relatively short half-life of 2-DG.  The free form of 2-DG is rapidly metabolized and rendered ineffective within minutes of entering the body.  In contrast, WP1122 has a half-life of approximately 6 hours, making it much more feasible to deliver quantities adequate for a therapeutic effect.

 

[1] Angiogenesis is the physiological process involving the growth of new blood vessels from pre-existing vessels and it is one of four fundamental elements in the progression of inflammatory and proliferative disorders, along with cell survival (where the normal process of cell death is switched off), abnormal or hyper-proliferation (where cells replicate too quickly) and immune system misdirection (where the immune system is either shut down or activated in the wrong way).

 

[2] SRC (pronounced “sarc”, as it is short for sarcoma) represents a family of tyrosine kinases (a type of enzyme that catalyzes the transfer of phosphate groups from high-energy, phosphate-donating molecules to specific substrates) often studied in connection with cancer research where normally healthy cellular signaling has gone awry. JAK represents another family of tyrosine kinases that transduce signals via the JAK-STAT pathway. They were initially named “just another kinase”, but were ultimately published as “Janus kinase” for the two-faced Roman god of doorways.  The Abelson oncogene or ABL is yet another tyrosine kinase linked to cancer and other inflammatory disease activation.  Because there are variations of each of these kinases within their respective families they are further differentiated by number, such as JAK1, JAK2, JAK3 and so on.
