Bladder Cancer Trial
The Borealis-2 trial evaluated apatorsen in combination with docetaxel treatment in 200 patients with metastatic bladder cancer whose disease had progressed following first-line platinum-based chemotherapy. The primary endpoint analysis met the superiority test for overall survival, performed at a one-sided 0.10 significance level using a stratified log-rank test.

Patients who received apatorsen treatment experienced a 20% reduction in risk of death, compared to patients receiving docetaxel alone (overall survival hazard ratio (HR)=0.80; 80% CI: 0.65-0.98; p=0.078).
Partial or complete responses occurred in 16.2% patients receiving apatorsen plus docetaxel compared to 10.9% patients receiving docetaxel alone with median response durations of 6.2 months versus 4.4 months, respectively.
Higher baseline serum Hsp27 levels were significantly prognostic for indicating an almost 2-fold higher risk of death (HR= 1.96; p=0.0001). In an exploratory analysis on a subset of patients (20% of total) who completed at least two treatment cycles and had either a decrease in serum Hsp27 levels from baseline or had only a 20.5% increase in serum Hsp27 levels from baseline, the reduction in risk of death with apatorsen treatment was 71% (HR= 0.29: 80% CI: 0.18-0.48; interaction p=0.0727).
Apatorsen was well tolerated in combination with docetaxel with a median treatment of 2 cycles.
The Borealis-2 trial was an investigator-sponsored trial conducted by the Hoosier Cancer Research Network at 28 sites across the United States.
Prostate Cancer Trial
The Pacific trial evaluated the ability of apatorsen, when added to Zytiga (abiraterone acetate), to reverse or delay treatment resistance in 72 men who were experiencing a rising PSA on Zytiga alone. The primary endpoint evaluated the proportion of patients who were progression free (clinical and radiologic) at study day 60 with apatorsen added to Zytiga, compared to continuing Zytiga alone.

In men receiving apatorsen, 33% were progression free at study day 60 compared to 17% for those men receiving Zytiga alone.
For patients with ≥5 circulating tumor cells (CTCs) at baseline, 22% vs 11% of patients had a CTC reduction to less than 5 CTCs when apatorsen was added to Zytiga vs Zytiga alone, respectively.
Apatorsen was well tolerated in combination with Zytiga with a median duration of 106 days.
The Pacific trial was an investigator-sponsored trial conducted by the Hoosier Cancer Research Network at sites in Canada and the United States.
"These data further reinforce our belief that by targeting heat shock protein 27 (Hsp27), apatorsen can improve outcomes of exisiting cancer therapies across various mechanisms of action, as demonstrated here with cytotoxic and hormonal treatments," said Scott Cormack, President and CEO of OncoGenex. "Given the biologic rationale for combining apatorsen with checkpoint inhibitors and other immune modulators, we are engaging in partnering discussions to further explore these development opportunities."

On February 21, 2017 Cell Medica, a leader in developing cellular immunotherapy for the treatment of cancer, reported the U.S. Food and Drug Administration (FDA) has granted Fast Track designation to its lead oncology product CMD-003 for patients with relapsed/refractory lymphoma and post-transplant lymphoproliferative disease associated with the oncogenic Epstein Barr virus (EBV) (Press release, Cell Medica Inc, FEB 21, 2017, View Source [SID1234517781]).

CMD-003, also known as baltaleucel-T, is an investigational therapy in which the patient’s T cells are activated to kill malignant cells expressing EBV antigens. The product has the potential to address a range of EBV-associated lymphomas, nasopharyngeal carcinoma and gastric cancer. The FDA Fast Track designation follows Orphan Drug Designations from both the FDA (EBV-associated non-Hodgkin lymphoma) and European Commission (extranodal NK/T lymphoma, nasal type and post-transplant lymphoproliferative disease).

The FDA’s Fast Track is a process designed to facilitate the development and to expedite the review of drugs to treat serious conditions and fill an unmet medical need. The FDA will take appropriate actions to advance the development and review of the application for approval of such a product. FDA Fast Track status also allows for more frequent interactions with the FDA review team and a rolling Biologics License Application (BLA) for earlier product review.

CMD-003 is currently being investigated in the international, open label Phase 2 CITADEL clinical trial for patients with extranodal natural killer T cell lymphoma (ENKTCL), a type of non-Hodgkin lymphoma. Cell Medica has also opened the Phase 2 CIVIC clinical trial to explore the potential benefits of CMD-003 for patients with EBV-associated diffuse large B cell lymphoma (DLBCL), Hodgkin lymphoma, and post-transplant lymphoproliferative disease (PTLD).

Dr Kurt Gunter, Chief Medical Officer of Cell Medica, said:

"The Fast Track designation supports the potential for CMD-003 to address an important area of high unmet clinical need. The potential eligibility for accelerated approval and priority BLA review will help facilitate the development of our lead cancer immunotherapy candidate. We are committed to bringing this novel treatment to patients as soon as possible."

On February 21, 2017 Bellicum Pharmaceuticals, Inc. (Nasdaq:BLCM), a leader in developing novel, controllable cellular immunotherapies for cancers and orphan inherited blood disorders, reported it has dosed the first patient with BPX-601, the first CAR T-cell product candidate to enter clinical studies that is designed to enable control over the expansion and stimulation of the cells (Press release, Bellicum Pharmaceuticals, FEB 21, 2017, View Source;p=RssLanding&cat=news&id=2247590 [SID1234517795]). BPX-601 targets solid tumors that express PSCA (prostate stem cell antigen), with an initial indication in non-resectable pancreatic cancer.

"We believe the initiation of the BPX-601 clinical study is an important milestone in the advancement of CAR T therapies," said Rick Fair, Bellicum’s President and CEO. "The ability to control the intensity and duration of a cell-based treatment may help address the limitations that current CAR T therapies face, especially when targeting solid tumors. While our first study is in pancreatic cancer where there is great need for improved treatments, we intend to explore BPX-601 in other tumors known to express PSCA, including prostate, ovarian, bladder, esophageal and gastric cancers."

BPX-601 incorporates GoCAR-TTM, a CAR T-cell modified to include Bellicum’s proprietary dual costimulatory domain MC (inducible MyD88/CD40) activation switch. With GoCAR-T, the level of stimulation and proliferation of BPX-601 cells can be refined by adjusting the administration schedule of rimiducid, a small molecule activator agent.

"This clinical trial is an important step in our ongoing research efforts to improve patient outcomes in one of the deadliest forms of cancer," said Carlos Becerra, MD, Interim Chief of Oncology, Baylor University Medical Center at Dallas and principal investigator of the study. "The pancreatic cancer patients who will be eligible to participate in the study have progressed after standard treatments and have limited options. We hope that this trial will be an important step in developing safe and effective CAR T-cell therapy for solid tumors."

About the BP-012 Study
The Phase 1 BP-012 study is an open-label, non-randomized, dose-finding trial designed to evaluate the safety and activity of BPX-601 and rimiducid in up to 30 patients with non-resectable pancreatic adenocarcinoma. Its purpose is to determine the safety of the administration of BPX-601, the safety of the rimiducid infusion and the persistence of the CAR T cells over time. The first of its kind trial for pancreatic cancer patients will take place at Baylor University Medical Center at Dallas, which is home to Baylor Scott & White Research Institute, one of the top translational research centers in the world. To learn more about the trial, visit clinicaltrials.gov.

About GoCAR-T
Bellicum developed GoCAR-T to increase the efficacy and safety of CAR T-cell therapies in more challenging cancers, including solid tumors. Standard CAR T cells depend on the presence of cancer antigens for activation and proliferation. In GoCAR-T cells, a costimulatory signal is engineered into a rimiducid-controlled switch. This is designed to enable T-cell survival in the absence of antigen signaling, and full activation and proliferation in the presence of cancer antigens. In the event of side effects, the level of activation of GoCAR-T cells may be attenuated by reducing the rimiducid dosing schedule.

On February 21, 2017 Oxis International, Inc. (OTCQB: OXIS) (OXIS.PA) parent company of Oxis Biotech, focused on the development and commercialization of immunotherapy for the treatment of cancer, reported it received notification from the U.S. Patent and Trademark Office a patent will be issued on February 28, 2017 for its drug candidate OXIS-4235 for the treatment of myeloma (Press release, OXIS International, FEB 21, 2017, View Source [SID1234539555]).

The patent clears the way for Oxis Biotech to begin the process of pursuing clinical trials for the new drug.

The drug is a P62-ZZ chemical inhibitor intended for use as a treatment for multiple myeloma. According to the American Cancer Society, more than 30,000 people are expected to be diagnosed with the disease this year and more than 12,000 are expected to die from it.

Dr. Sean Xie of Pittsburgh, Pa., developed the drug. The drug is intended to stop the growth of multiple myeloma cells without harming healthy cells. In addition to shrinking the tumors, the dual purpose drug is also intended to increase bone density, a second benefit of the technology.

Oxis Biotech, through its licensing agreement with Dr. Xie, holds the exclusive worldwide rights to commercialize this technology.

"Bone density shrinkage is one of the biggest problems of multiple myeloma. Bones wither away. This dual action drug is extremely promising," said Oxis CEO Anthony Cataldo. "We have always had great confidence in Dr. Xie’s work related to multiple myeloma. The issuance of this patent points out the unique and novel technology Dr. Xie has developed. We are incredibly happy to add it to our pipeline."

The USPTO indicated it will issue Patent No. 9,580,382 for the technology on February 28, 2017.
