The research collaboration is intended to complement RedHill’s planned Phase Ib clinical study to evaluate YELIVA as a radioprotectant for prevention of mucositis in head and neck cancer patients undergoing therapeutic radiotherapy.

As part of the collaboration, Stanford will evaluate the effect of YELIVA on mucositis reduction and tumor control in a murine model of head and neck cancer. YELIVA will be administered in combination with a chemotherapy agent and radiotherapy, similar to the design of RedHill’s planned radioprotectant Phase Ib clinical study with YELIVA, expected to run in parallel with the Stanford research collaboration. Results from the research collaboration are expected in mid-2017.

The Stanford research collaboration is led by Dr. Quynh-Thu Le, MD, a radiation oncologist, Chair of the Stanford Radiation Oncology Department, Co-Director of the Radiation Biology Program of the Stanford Cancer Institute and the Chair of the Head and Neck Cancer Committee of the NRG Oncology Group, part of the National Cancer Institute (NCI) supported National Clinical Trial Network (NCTN).

YELIVA is a proprietary, first-in-class, orally-administered, sphingosine kinase-2 (SK2) selective inhibitor with anti-cancer and anti-inflammatory activities. By inhibiting the SK2 enzyme, YELIVA blocks the synthesis of sphingosine 1-phosphate (S1P), a lipid signaling molecule that promotes cancer growth and pathological inflammation.

RedHill is pursuing with YELIVA multiple clinical programs in oncology, inflammatory and gastrointestinal indications. RedHill is evaluating potential clinical studies for additional oncology and inflammatory indications, as well as potential collaboration opportunities to evaluate YELIVA as an add-on therapy.

Results from the Phase I study with YELIVA in patients with advanced solid tumors confirmed that the study, conducted at the Medical University of South Carolina (MUSC), successfully met its primary and secondary endpoints, demonstrating that the drug is well- tolerated and can be safely administered to cancer patients at doses that provide circulating drug levels that are predicted to have therapeutic activity.

Among the 16 subjects that were assessable for response by RECIST 1.1 criteria (Response Evaluation Criteria in Solid Tumors), one subject had a partial response with a progression-free survival of 16.9 months, and six subjects had stable disease with a progression-free survival of between 3.5 and 17.6 months. Of the three patients with cholangiocarcinoma, one had a partial response and the other two had stable disease, one for over a year. YELIVA was well-tolerated over a prolonged period at doses inducing the expected pharmacodynamic effects.

A Phase Ib/II study with YELIVA for the treatment of refractory or relapsed multiple myeloma has recently been initiated at Duke University Medical Center. The study is supported by a $2 million grant from the National Cancer Institute (NCI) Small Business Innovation Research Program (SBIR) awarded to Apogee Biotechnology Corp. (Apogee), in conjunction with Duke University, with additional support from RedHill.

A Phase II study with YELIVA for the treatment of advanced hepatocellular carcinoma is planned to be initiated in the coming weeks. The study will be conducted at MUSC Hollings Cancer Center and additional clinical centers in the U.S. It is supported by a $1.8 million grant from the NCI awarded to MUSC, intended to fund a broad range of studies on the feasibility of targeting sphingolipid metabolism for the treatment of a variety of solid tumor cancers, including the Phase II study with YELIVA and will be further supported by additional funding from RedHill.

A Phase I/II clinical study evaluating YELIVA in patients with refractory/relapsed diffuse large B-cell lymphoma (DLBCL) was initiated at the Louisiana State University Health Sciences Center (LSUHSC) in New Orleans in June 2015 and is expected to resume later this year following administrative hold and pending a protocol amendment aimed at improving overall recruitment. The study is supported by a grant awarded to Apogee from the NCI as well as additional support from RedHill.

The studies with YELIVA (ABC294640) are registered on www.ClinicalTrials.gov, a web-based service by the U.S. National Institute of Health, which provides public access to information on publicly and privately supported clinical studies.

About YELIVA (ABC294640):
YELIVA (ABC294640) is a Phase II-stage, proprietary, first-in-class, orally-administered, sphingosine kinase-2 (SK2) selective inhibitor with anti-cancer and anti-inflammatory activities. RedHill is pursuing with YELIVA multiple clinical programs in oncology, inflammatory and gastrointestinal indications. By inhibiting the SK2 enzyme, YELIVA blocks the synthesis of sphingosine 1-phosphate (S1P), a lipid signaling molecule that promotes cancer growth and pathological inflammation. SK2 is an innovative molecular target for anticancer therapy because of its critical role in catalyzing the formation of S1P, which is known to regulate cell proliferation and activation of inflammatory pathways. YELIVA was originally developed by U.S.-based Apogee Biotechnology Corp. and completed multiple successful pre-clinical studies in oncology, inflammation, GI and radioprotection models, as well as the ABC-101 Phase I clinical study in cancer patients with advanced solid tumors. The development of YELIVA was funded to date primarily by grants and contracts from U.S. federal and state government agencies awarded to Apogee Biotechnology Corp., including the U.S. National Cancer Institute, the U.S. Department of Health and Human Services’ Biomedical Advanced Research and Development Authority (BARDA), the U.S. Department of Defense and the FDA Office of Orphan Products Development.

On September 12, 2016 CytRx Corporation (NASDAQ: CYTR), a biopharmaceutical research and development company specializing in oncology, reported that results from its on-going Phase 1b/2 trial of aldoxorubicin in combination with ifosfamide/mesna in patients with advanced sarcomas will be presented at the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) 2016 Congress being held in Copenhagen, Denmark, from October 7-11, 2016 (Press release, CytRx, SEP 12, 2016, View Source;p=RssLanding&cat=news&id=2201143 [SID:SID1234515090]).

"Presenting the results from this trial at the ESMO (Free ESMO Whitepaper) Congress underscores the continued anti-tumor activity of aldoxorubicin across a variety of treatment settings for patients with advanced sarcomas," said Sant Chawla, M.D., F.R.A.C.P., the trial’s principal investigator and Director of the Sarcoma Oncology Center in Santa Monica, California. "The data show that aldoxorubicin can successfully be combined with ifosfamide and mesna, which are regularly given with doxorubicin to patients with first-line soft tissue sarcomas. Based on encouraging results, the trial was expanded to 50 patients and continues to enroll."

The Phase 1b/2 clinical trial has enrolled 38 patients to date with locally advanced, unresectable, and/or metastatic soft tissue sarcoma, intermediate-grade or high-grade chondrosarcoma or osteosarcoma. In the dose escalation phase, patients received either 170mg/m2 or 250mg/m2 of aldoxorubicin in combination with up to a 14-day continuous infusion of ifosfamide (1g/m2/day) plus mesna over a 28-day cycle. The expansion phase will enroll patients at the 250mg/m2 dose of aldoxorubicin and will allow for patients that had received prior chemotherapy to be included. The primary endpoint of the study is safety, and secondary endpoints include overall response rates and progression-free survival.

About Aldoxorubicin

Aldoxorubicin is a rationally-engineered cytotoxic which combines doxorubicin, a widely used chemotherapeutic agent, with a novel linker molecule that binds directly and specifically to circulating albumin, the most abundant protein in the bloodstream. Protein-hungry tumors concentrate albumin, which facilitates the delivery of the linker molecule with the attached doxorubicin to tumor sites. In the acidic environment of the tumor, but not the neutral environment of healthy tissues, doxorubicin is released. Typically, doxorubicin is delivered systemically and is highly toxic, which limits its dose to a level below its maximum therapeutic benefit. Doxorubicin also is associated with many side effects, especially the potential for damage to heart muscle at cumulative doses greater than 450 mg/m2. Using this acid-sensitive linker technology, aldoxorubicin delivers greater doses of doxorubicin (3 ½ to 4 times). To date, there has been no evidence of clinically significant effects of aldoxorubicin on heart muscle, even at cumulative doses of drug well in excess of 2,000 mg/m2. Aldoxorubicin is the first-ever single agent to show superiority over doxorubicin in a randomized clinical trial in first-line STS.

On September 12, 2016 Circle Pharma, Inc., reported that it will apply its computational design and synthetic chemistry platform to design and create a physical screening library of novel macrocyclicpeptides (Press release, Circle Pharma, SEP 12, 2016, View Source [SID1234635670]). Once completed, the library is initially expected to comprise several hundred macrocycles that will be designed to potentially disrupt bioactive conformations commonly found in protein-protein interactions known to drive disease processes, and will deploy backbone scaffolds screened in silica for intrinsic cell permeability characteristics. In addition, the design of the library will permit the simple creation of derivative libraries tailored to specific features of a therapeutic target class.

PfizerInc.(NYSE:PFE) has entered into an agreement with Circle under which Pfizer will provide support for the library build, and Circle has granted Pfizer non-exclusive rights to screen the library against certaintargets. The rights granted to Pfizer exclude specified targets for which Circle has reserved exclusive rights to screen the library.

"This physical library will complement Circle’s target-specific computational design toolkit," said David J. Earp, J.D., Ph.D., Circle’s President and CEO. "We expect to use the library for our internal pipeline discovery work, and we will make it available to all of our collaboration partners in drug discovery."

About Macrocyclic Peptides

Macrocyclic peptides have the potential to provide access to the large proportion of therapeutic targets (estimated at up to 80%) that are considered undruggable with conventional small molecule or biologic modalities. Inparticular, there is great interest in developing macrocycles to modulate protein-protein interactions, which play a role in almost all disease conditions, including cancer, fibrosis, inflammation and infection. However, the development of macrocyclic therapeutics has been limited to this point by the need for a greater understanding of how to design macrocycles with appropriate pharm acokinetics, cell permeability and oral bioavailability. As a result, most clinical-stage macro cyclic peptide drugs address extracellular protein targets because of the challenge of identifying cell permeable macrocycles. The ability to design potent macrocycles with intrinsic permeability is expected to give access to a large number of important therapeutic targets that have been out of reach to this point.

On September 12, 2016 Aptose Biosciences Inc. (NASDAQ:APTO) (TSX:APS), a clinical-stage company developing new therapeutics and molecular diagnostics that target the underlying mechanisms of cancer, reported that it has submitted a formal response to the U.S. Food and Drug Administration (FDA) regarding the previously announced clinical hold of Aptose’s Phase 1b clinical trial of APTO-253 in patients with hematologic cancers (Press release, Aptose Biosciences, SEP 12, 2016, View Source;p=RssLanding&cat=news&id=2201082 [SID:SID1234515091]). Aptose provided responses to all of the questions cited in the clinical hold letter issued by the FDA.

"This submission represents months of disciplined labor to resolve a manufacturing matter related to APTO-253 that arose during our Phase 1b Trial in patients with AML and high-risk MDS," commented Dr. William G. Rice, Chairman, President and Chief Executive Officer. "Although the FDA will make the ultimate decision whether our clinical trial may resume, all of their questions have been addressed."

During a Phase 1b clinical trial with APTO-253, a clinical site experienced stoppage of the infusion pump during an IV infusion caused by back pressure as a result of clogging of the in-line filter. The Company determined the root cause was a chemistry-based issue with the molecule, and the Company is now working with a drug product that does not cause filter clogging or pump stoppage during mock infusion studies performed to confirm the acceptability of the updated product through the clinical infusion procedures. Such improvements to the APTO-253 manufacturing process required to address the filter clogging event will be incorporated into a Chemistry, Manufacturing and Control (CMC) amendment to our Investigational New Drug application.
