"We are excited that Cancer Research UK has expanded the clinical investigation of taladegib through the initiation of this combination study"
"We are excited that Cancer Research UK has expanded the clinical investigation of taladegib through the initiation of this combination study," said Jonathan Lim, M.D., Chairman and CEO of Ignyta. "We look forward to supporting Cancer Research UK in this trial, and to evaluating the data, including potentially identifying the impact of this therapeutic intervention on the hedgehog pathway at both the mRNA and protein levels and correlating these changes with the patients’ disease and potential clinical response."
About Taladegib
Taladegib, which Ignyta exclusively licensed from Eli Lilly and Company in November 2015, is a potent, orally bioavailable small molecule hedgehog/smoothened antagonist that has achieved clinical proof-of-concept and a recommended Phase 2 dose based on results from prior clinical studies. Ignyta believes taladegib represents a potential first-in-class hedgehog/smoothened inhibitor for second-line treatment of locally advanced or metastatic basal cell carcinoma, as well as a potential best-in-class hedgehog/smoothened inhibitor for first-line treatment of these patients. In addition, Ignyta believes taladegib alone or in combination has the potential to treat selected patients with solid tumors outside of basal cell carcinoma that are driven by hedgehog pathway alterations. Ignyta also granted back to Lilly exclusive rights for Lilly to develop and commercialize taladegib-containing products in combination with certain Lilly compounds.

OXiGENE also announced that the U.S. Food and Drug Administration (FDA) has approved the protocol for FOCUS, OXiGENE’s phase 2/3 study of CA4P for the treatment of platinum-resistant ovarian cancer. FOCUS will test whether CA4P, the company’s lead investigational drug, improves progression-free survival (PFS) when combined with bevacizumab (Avastin) and chemotherapy. If the trial is successful, data from FOCUS would be used as the basis for a new drug application to the FDA.
"I am pleased that we have approval from the FDA to proceed with FOCUS, our planned clinical trial in platinum-resistant ovarian cancer," stated William D. Schwieterman, M.D., President and Chief Executive Officer of OXiGENE. "We have engaged a well-qualified clinical research organization to assist us with this trial, and intend to begin patient enrollment in the second quarter of this year. While we continue to develop and plan for a similar study in glioblastoma multiforme, and continue to see this as an outstanding opportunity to expand our pipeline, we will not initiate this study in 2016 as most of our current efforts for developing CA4P will be on FOCUS."
FOCUS is a randomized double-blind placebo-controlled study divided into two parts to maximize the speed of data collection. During stage 1 (n= up to 80 patients), serial interim analyses will be conducted to initially assess the efficacy and safety of the combination regimen when compared to standard-of-care. Stage 2 (n= approximately 356 patients) is a confirmatory phase 3 study which would begin immediately after evidence of safety and efficacy are initially demonstrated in stage 1.
FOCUS is designed to build upon data from the GOG-0186I study, first announced in 2014, which demonstrated that CA4P improves PFS in women with recurrent ovarian cancer when combined with bevacizumab compared to bevacizumab alone. The treatment effect observed in this study was strongest in the subgroup of ovarian cancer patients with platinum-resistant disease.

TRILLIUM THERAPEUTICS DOSES FIRST PATIENT WITH TTI-621, A NOVEL IMMUNE CHECKPOINT INHIBITOR TARGETING CD47
On February 3, 2016 Trillium Therapeutics Inc. (NASDAQ:TRIL)(TSX:TR) a clinical stage immuno-oncology company developing innovative therapies for the treatment of cancer,reported that it has initiated dosing in its Phase 1 clinical trial of TTI-621 (SIRPaFc), a novel checkpoint inhibitor of the innate immune system, in relapsed or refractory hematologic malignancies (Press release, Trillium Therapeutics, FEB 3, 2016, View Source [SID:1234508969]).

TTI-621 is an antibody-like fusion protein that blocks the inhibitory activity of CD47, a molecule that is overexpressed by a wide variety of tumors. CD47 binds to SIRPa on macrophages and delivers a "do not eat" signal that inhibits the ability of macrophages to engulf and destroy cancer cells. Preclinical studies have shown that TTI-621 has anti-tumor activity across a range of hematologic tumors.
"This is an exciting time for Trillium as we now emerge as a clinical stage oncology company evaluating a novel immune checkpoint inhibitor," commented Dr. Eric Sievers, Trillium’s Chief Medical Officer. "At a fundamental level, a cancer patient’s ineffective immune response allows the tumor to propagate unchecked. By blocking CD47, a key cell-surface protein that inhibits phagocytosis, we hope to summon a durable anti-tumor response in patients who are beset by cancer."
The two-part clinical trial is designed as a multi-center, open-label Phase 1a/1b trial, evaluating TTI-621 as a single-agent in patients with relapsed or refractory hematologic malignancies. During the dose escalation phase set to enroll up to 36 subjects, the safety, tolerability, pharmacokinetics and pharmacodynamics will be characterized to determine the optimal dose for subsequent enrollment in the expansion phase. In this second part of the trial, the safety and preliminary antitumor activity of TTI-621 at the optimal dose identified in the escalation phase will be explored in 12-15 subjects per hematologic malignancy type: indolent B-cell lymphoma, aggressive B-cell lymphoma, T-cell lymphoma, Hodgkin lymphoma, chronic lymphocytic leukemia, multiple myeloma, acute myeloid leukemia, and myelodysplastic syndrome.
Trillium has proposed five trial sites including the Mayo Clinic, Columbia University Medical Center, City of Hope National Medical Center, The Colorado Blood Cancer Institute, and Tennessee Oncology.
