Calithera Announces First Patient Dosed in a Phase I Study of CB-1158, the First-in-Class Inhibitor of the Immuno-Oncology Target Arginase
On September 15, 2016 Calithera Biosciences, Inc. (Nasdaq:CALA), a clinical stage biotechnology company focused on the development of novel cancer therapeutics, reported that the first patient has been dosed in a Phase I clinical trial assessing the safety and efficacy of CB-1158, a first-in-class arginase inhibitor for the treatment of advanced solid tumors (Press release, Calithera Biosciences, SEP 15, 2016, View Source [SID:SID1234515171]). Arginase is an enzyme in myeloid-derived suppressor cells (MDSCs), which prevents T-cell and natural killer (NK) cell activation in tumors. Schedule your 30 min Free 1stOncology Demo! "Arginase, when released by MDSCs, plays an important role in the inhibition of T-cell and NK-cell activation and proliferation, preventing immune-mediated anti-tumor activity. For example, in many solid tumors, including lung, colorectal, esophageal, bladder, head and neck, and kidney cancer, arginase-expressing MDSCs accumulate, establishing an immunosuppressive microenvironment by blocking the ability of T-cells and NK-cells to kill cancer cells. We believe that inhibitors of arginase can promote an anti-tumor immune response and augment the activity of checkpoint inhibitors," said Susan M. Molineaux, Ph.D., founder, Chief Executive Officer and President of Calithera Biosciences. "We look forward to reporting initial clinical results with this compound in 2017."

Arginase exerts its immunosuppressive effect by depleting the amino acid arginine in the tumor microenvironment and preventing activation and proliferation of the immune system’s cytotoxic T-cells and NK-cells. We believe that inhibitors of arginase activity promote an anti-tumor immune response by restoring arginine levels in the tumor and reversing this immunosuppressive metabolic checkpoint. The Phase I clinical trial will enroll patients with advanced solid tumors treated with CB-1158 as a monotherapy, as well as in combination with an anti-PD1 therapy.

Celsion Corporation Announces Positive DSMB Review of Phase 1b OVATION Study in Ovarian Cancer
On September 15, 2016 Celsion Corporation (NASDAQ:CLSN) reported that the independent Data Safety Monitoring Board (DSMB) has completed its safety review of data from the first three patient cohorts in the ongoing Phase Ib OVATION Study (Press release, Celsion, SEP 15, 2016, View Source [SID:SID1234515152]). Based on the DSMB’s recommendation, the study will continue as planned and the Company will proceed with dosing in its fourth and final patient cohort at an escalated dose. The OVATION Study is a dose-escalating clinical trial combining GEN-1, the Company’s DNA-based immunotherapy, with the standard of care for the treatment of newly-diagnosed patients with advanced ovarian cancer who will undergo neoadjuvant chemotherapy followed by interval debulking surgery. Schedule your 30 min Free 1stOncology Demo! "The DSMB’s recommendation and the lack of any dose limiting toxicities in the trial to date underscore the improved tolerability of GEN-1 over recombinant IL-12 protein-based therapies," said Nicholas Borys, M.D., senior vice president and chief medical officer of Celsion. "The favorable safety profile we have seen thus far is consistent with the translational data that we reported earlier this year, which show that GEN-1 produces a sustained, localized secretion of IL-12 protein and avoids the high levels of systemic exposure which have limited the development of recombinant IL-12 therapies in the past."

"We could not be more excited to progress with the OVATION Study and look forward to reporting clinical findings from the third patient cohort, as well as translational data from the first two cohorts, early in the fourth quarter. Furthermore, we expect to report final data from this highly promising study in the first quarter of 2017," said Michael H. Tardugno, Celsion’s chairman, CEO and president. "We have been encouraged, as have been our Investigators, by the findings to-date in this difficult-to-treat patient population. As we have previously reported, all six patients in the first two cohorts experienced a clinically meaningful response, ranging from stable disease to one pathologically confirmed complete response. In addition, we saw sustained decreases of 90% or greater of the prospective indicator of the presence of ovarian cancer cells, CA-125 protein, in all patients, as well as highly impressive pathologically responses, which is associated with prolonged survival."
The OVATION Study is designed to enroll three to six patients per dose cohort at escalating doses of GEN-1 with the goal to identify a safe, tolerable and therapeutically active dose of GEN-1 by recruiting and maximizing an immune response. The first three cohorts each enrolled three patients. Enrollment in the fourth and final cohort is underway, and Celsion expects to report full data from the OVATION Study by the first quarter of 2017. Future studies of GEN-1 will include a Phase I/II study combining GEN-1 with Avastin and Doxil.

ARQ 087 is being dosed in intrahepatic cholangiocarcinoma (iCCA) patients with FGFR2 genetic alterations as part of the phase 2 portion of a biomarker driven phase 1/2 trial. The company has been granted orphan drug designation by the U.S. Food and Drug Administration and European Medicines Agency for ARQ 087 in this indication.
About Intrahepatic Cholangiocarcinoma
Cholangiocarcinoma (CCA) is the most common biliary malignancy and the second most common hepatic malignancy after hepatocellular carcinoma (HCC)1. Depending on the anatomic location, CCA is classified as intrahepatic (iCCA), perihilar (pCCA), and extrahepatic (eCCA). iCCA originates from the intrahepatic biliary ductal system and forms an intrahepatic mass. The average age adjusted incidence rate for iCCA is approximately one in 100,000 per year in the United States and Europe2,3.
About FGFR and ARQ 087
ARQ 087 is a multi-kinase inhibitor designed to preferentially inhibit the fibroblast growth factor receptor ("FGFR") family with demonstrated activity in FGFR2 genetic alterations. The FGFR pathway is disrupted in several ways in human cancer, thus providing numerous therapeutic targets for an inhibitor of this pathway. ARQ 087 has demonstrated in vivo inhibition of tumor growth and downstream signaling in tumors whose growth is driven by FGFR targets.
Signals of single agent activity with this drug were observed in phase 1a testing. Phase 1b expansion cohorts with ARQ 087 include patients with cholangiocarcinoma and adrenocortical tumors, as well as those with FGFR translocations, amplifications and mutations. Clinical development of ARQ 087 has advanced into phase 2 for intrahepatic cholangiocarcinoma (iCCA) following the observation of two confirmed responses in this patient population in the phase 1 portion of the program.
