On January 4, 2018 Rasna Therapeutics, Inc. (OTCQX: RASP), a clinical stage biotechnology company focused on the development of disease-modifying drugs for hematological malignancies, reported follow up Phase II clinical data showing that 4 out of 9 (44%) evaluable AML patients carrying the NPM1 gene mutation treated with actinomycin D ("Act D"), achieved complete remission (CR) (Press release, Rasna Therapeutics, JAN 4, 2018, View Source [SID1234522893]). Treatment with Act D was well-tolerated except that patients experienced oral mucositis as the major toxicity. Rasna Therapeutics has developed a proprietary nanoparticle based formulation of Act D (RASP-101), which is anticipated to maximize efficacy while minimizing oral mucositis. RASP-101 could potentially be a first-in-class modality for treatment of NPM1-mutated acute myeloid leukemia (AML).
NPM1-mutated AML is a specific genetic leukemia entity that accounts for approximately one-third cases of AML in adults. As we reported previously, intravenous treatment of refractory or relapsed NPM1-mutated AML patients with Act D (12.5 µg or 15 µg/day) for 5 consecutive days produced hematological complete response in some of them (Falini et al., N Eng J Med. 373: 12, 2015).

In a follow-up phase II clinical study (ActD-AML-PG01, EudraCT 2014-000693-18) in refractory/relapse (R/R) AML patients carrying NPM1 gene mutation, treatment with Act D at 15 µg/kg/day for 5 days every 28 days induced CR in 4 out of the 9 evaluable patients (44.4%) with only 1 or 2 cycles of therapy. Three out of the 4 (75%) patients who obtained CR relapsed after 3, 5 and 7 months, respectively. One patient underwent haploidentical allogeneic PBSC transplantation at 3 months after CR achievement and is alive in molecular CR (MRD-negative) after 24 months.

"The precise mechanism of action of Act D in NPM1-mutated AML is still not clearly understood. Follow up data confirms our earlier findings and further support the use of Act D to induce complete hematological remissions with possible long-term molecular responses in NPM1-mutated AML patients. To note, our first previously reported NPM1-mutated AML patient (resistant to hypomethylating therapy) treated with Act D remains in molecular remission at over 3 years since CR achievement," said Dr. Brunangelo Falini, a member of the scientific advisory board of Rasna Therapeutics, Inc.

"We have developed a proprietary formulated Act D (RASP-101), which we anticipate will produce a superior clinical outcome with improved efficacy and safety profile. Emerging data from the multicenter clinical studies will allow us to develop a biomarker strategy to select responsive patients and improve clinical outcome for this unmet clinical need" commented Alessandro Padova, Chairman of Rasna.

About Phospholipid Drug Conjugates (PDCs)

Cellectar’s product candidates are built upon its patented cancer cell-targeting delivery and retention platform of optimized phospholipid ether-drug conjugates (PDCs). The company deliberately designed its phospholipid ether (PLE) carrier platform to be coupled with a variety of payloads to facilitate both therapeutic and diagnostic applications. The basis for selective tumor targeting of our PDC compounds lies in the differences between the plasma membranes of cancer cells compared to those of normal cells. Cancer cell membranes are highly enriched in lipid rafts, which are glycolipoprotein microdomains of the plasma membrane of cells that contain high concentrations of cholesterol and sphingolipids, and serve to organize cell surface and intracellular signaling molecules. PDCs have been tested in more than 80 different xenograft models of cancer.

On January 4, 2018 Onconova Therapeutics, Inc. (NASDAQ:ONTX), a Phase 3 stage biopharmaceutical company focused on discovering and developing novel small molecule drug candidates to treat cancer, with a primary focus on Myelodysplastic Syndromes (MDS), reported that it has entered into a Cooperative Research and Development Agreement (CRADA) with the National Cancer Institute (NCI), part of the National Institutes of Health (NIH) (Press release, Onconova, JAN 4, 2018, View Source [SID1234522892]). Under the terms of the CRADA, the NCI will conduct research, including preclinical laboratory studies and a clinical trial, on rigosertib in pediatric cancer associated RASopathies.

The RASopathies are a group of rare diseases which share a well-defined molecular basis in expression or defects involving Ras Effector Pathways. They are usually caused by germline mutations in genes that alter the RAS subfamily and mitogen-activated protein kinases that control signal transduction, and are among the most common genetic syndromes. Together, this group of diseases can impact more than 1 in 1000 individuals, according to RASopathiesNet.

Dr. Steve Fruchtman, Chief Medical Officer of Onconova, noted: "We are excited about the potential of our collaboration with the Pediatric Oncology Branch at NCI’s Center for Cancer Research in the study of rigosertib in children with both hematological and solid tumors that are driven by the Ras pathway. This collaboration could lead to important advances in the treatment of these refractory tumors. This novel approach directed at a specific mechanism driving the underlying neoplasm is the basis of personalized medicine for these indications".

As part of the CRADA, Onconova will provide rigosertib supplies and initial funding towards non-clinical studies. The NCI will fund the majority of the research, including the cost of the clinical trial, which is expected to start in 2018. A clinical trial protocol has been developed and will be reviewed by the Institutional Review Board.

Onconova is also collaborating with academic researchers and patient advocacy groups interested in developing novel therapeutics to address the needs of these patients. In October 2017, Onconova held a Key Opinion Leader Breakfast Symposium in New York City to bring attention to this unmet medical need and the potential for rigosertib in RASopathies. The meeting featured presentations by Bruce D. Gelb, M.D. (Mount Sinai, New York) and Elliot Stieglitz, M.D. (University of California, San Francisco), alongside Dr. Fruchtman. In July 2017, Onconova also presented a summary of its targeted approach at a symposium organized by RASopathiesNet.org.

While the NCI will conduct a trial for RASopathy related cancers in pediatric patients, Onconova will focus on Juvenile Myelomonocytic Leukemia (JMML), a well-described RASopathy affecting children which is incurable without an allogenic hematopoietic stem cell transplant.

Additional information highlighting Onconova’s approach to studying rigosertib in RAS mediated diseases can be found in the presentation, "Strategies to RASopathies and JMML," located in the "Scientific Presentations" section of Onconova’s website.

About GC4419

GC4419 is a highly selective and potent small molecule dismutase mimetic that closely mimics the activity of human superoxide dismutase enzymes. GC4419 works to reduce elevated levels of superoxide free radical levels caused by radiation therapy by rapidly converting superoxide free radical molecules to hydrogen peroxide and oxygen. Left untreated, elevated superoxide free radicals can damage noncancerous tissues and lead to debilitating side effects, including oral mucositis (OM), which can limit the antitumor efficacy of radiation therapy.

GC4419 is initially being studied for its ability to reduce the incidence, duration and severity of radiation and chemotherapy-induced OM in patients with head and neck cancer. As reported in December 2017, top-line results from Galera’s 223-patient, double blind, randomized, placebo-controlled Phase 2b clinical trial demonstrate GC4419’s ability to dramatically reduce the duration of severe OM from 19 days to 1.5 days (92 percent), the incidence of severe OM through completion of radiation by 34 percent and the severity of patients’ OM by 47 percent, while preserving healthy tissue. In addition, in preclinical study GC4419 demonstrated an increased tumor response to radiation therapy while preventing toxicity in normal tissue.

The U.S. Food and Drug Administration granted Fast Track designation to GC4419 for the reduction and incidence of radiotherapy induced OM in patients with head and neck cancer. GC4419 also has potential in other indications in which mucosa is damaged by radiation.

About Oral Mucositis

Oral mucositis (OM) is a painful and problematic complication during cancer treatment, especially radiation therapy, caused by excessive superoxide generated during treatment that breaks down epithelial cells that line the mouth. Patients suffering from OM experience severe pain, inflammation, ulceration and bleeding of the mouth.

In the United States, more than 50 percent of patients with cancer receive radiotherapy at some time in their treatment. In patients with head and neck cancer, radiotherapy is a mainstay of treatment and approximately 70 percent of patients receiving chemoradiotherapy develop severe oral mucositis (SOM) as defined by the World Health Organization as Grade 3 or 4, which is the most debilitating side effect of the radiotherapy.

SOM can adversely affect cancer treatment outcomes by causing interruptions in radiotherapy, which may compromise the otherwise good prognosis for tumor control in many of these patients. SOM may also inhibit patients’ ability to eat solid food or even drink liquids, and can cause serious infections. Further, the costs of managing these side effects are substantial, particularly when hospitalization and/or surgical placement of PEG tubes to maintain nutrition and hydration are required. There is currently no drug approved to prevent or treat SOM in patients with head and neck cancer.
