"I am pleased to announce today’s promotions which highlight the talent, skill set and extensive achievements of our executive team," said Susan Molineaux, PhD, President and Chief Executive Officer of Calithera. "It is critical that we have the right leadership in place to reach key clinical milestones as we drive CB-839 towards commercialization with two randomized trials of the glutaminase inhibitor CB-839 for the treatment of patients with advanced renal cell carcinoma. We plan to report data from our Phase 2 ENTRATA trial in 2019, and the global CANTATA trial in 2020. In 2019, we look forward to a number of achievements including the initiation of additional clinical trials of CB-839 in collaboration with Pfizer, and the presentation of data on the arginase inhibitor INCB001158 at a medical meeting in the second half of 2019. Our goal is to have four unique therapeutics in the clinic including CB-280, an oral arginase inhibitor for the treatment of patients with cystic fibrosis, and CB-708, an oral small molecule CD73 inhibitor for the treatment of cancer by the end of 2019."

2019 Milestones

Calithera expects to reach the following milestones in 2019:

CB-839 data from Phase 2 renal cell carcinoma randomized ENTRATA trial 2H19. The ENTRATA trial is a randomized, double-blind trial designed to evaluate the safety and efficacy of CB-839 with everolimus versus everolimus alone in approximately 63 patients with metastatic, clear cell renal cell carcinoma patients who have been treated with at least two prior lines of therapy including a VEGFR-targeting tyrosine kinase inhibitor. The primary endpoint is progression free survival; overall survival will be assessed as a secondary endpoint.

CB-839 enrollment of the Phase 2 renal cell carcinoma CANTATA trial 2H19. The CANTATA trial is a randomized, global, double-blind trial comparing patients treated with CB-839 and cabozantinib to patients treated with cabozantinib alone. The trial will enroll approximately 400 patients with clear cell renal cell carcinoma who have previously received one or two prior lines of therapy. The U.S. Food and Drug Administration (FDA) has granted Fast Track designation for CB-839 in combination with cabozantinib for the treatment of this patient population.

CB-839 combination trial initiations in collaboration with Pfizer 1H19. Calithera and Pfizer have two clinical trial collaborations to evaluate Pfizer’s CDK4/6 inhibitor palbociclib, also known as IBRANCE, and the dual-mechanism poly (ADP-ribose) polymerase (PARP) inhibitor talazoparib also known as TALZENNA, each in combination with the glutaminase inhibitor CB-839.

INCB001158 arginase inhibitor data presentation at a medical meeting 2H19. INCB001158 is a small molecule immuno-oncology therapeutic being evaluated in multiple clinical trials as a single-agent and in combination with immunotherapies and chemotherapy for the treatment of patients with cancer. INCB001158 is being developed as part of a collaboration and license agreement with Incyte.

CB-280 IND acceptance and Phase 1 trial initiation in healthy volunteers 1H19. CB-280 is an arginase inhibitor for the treatment of cystic fibrosis. Arginase is believed to be critical in the pathology of cystic fibrosis. It impairs production of nitric oxide and generates metabolites of arginine that may impair lung function. CB-280 is an orally administered small molecule inhibitor of arginase. An investigational new drug (IND) application for CB-280 is planned for the first half of 2019.

CB-708 IND acceptance and Phase 1 trial initiation 2H19. The immuno-oncology target CD73 is an enzyme that plays a critical role in the process of ATP conversion to adenosine. An IND application for CB-708, an orally administered small molecule inhibitor of CD73, is planned for 2019.

Selected Fourth Quarter 2018 Financial Results and Financial Guidance for 2019

Based upon preliminary estimates, cash, cash equivalents and investments totaled $136.2 million at December 31, 2018. Calithera expects to utilize cash and investments between $75 and $85 million in 2019.

"We continue to work closely with Novartis across multiple programs in the collaboration, and both companies are eager to advance XmAb14045 in clinical development. Recently we presented encouraging early data from our Phase 1 study in patients with relapsed/refractory AML, observing multiple complete remissions on a weekly dosing schedule, and we continue to optimize dose in that study. Novartis also has internal XmAb preclinical bispecific programs progressing," said Bassil Dahiyat, Ph.D., president and chief executive officer at Xencor. "Xencor will continue to develop XmAb13676 as planned, and we believe its tuned potency holds potential for the treatment of patients with B-cell malignancies."

Under the terms of the collaboration agreement, Xencor and Novartis continue to share costs for the worldwide development of XmAb14045 with Xencor maintaining U.S. commercialization rights and Novartis having commercialization rights in the rest of the world, and worldwide development costs for XmAb13676 will be shared until June 2020. Novartis received worldwide rights to Xencor’s bispecific technology to develop and commercialize four additional targets selected by Novartis. Xencor is eligible to receive clinical, regulatory and sales milestone payments for successful programs, as well as tiered, low double-digit royalties for sales of XmAb14045 outside of the U.S. and mid single-digit tiered royalties for worldwide sales of the four proprietary Novartis bispecific molecules.

About XmAb13676

XmAb13676 is a tumor-targeted antibody that contains both a CD20 binding domain and a cytotoxic T-cell binding domain (CD3) in a Phase 1 clinical trial for the treatment of B-cell malignancies. An XmAb bispecific Fc domain serves as the scaffold for these two antigen binding domains and confers long circulating half-life, stability and ease of manufacture on XmAb13676. CD20 is highly expressed on B-cell tumors, including in chronic lymphocytic leukemia (CLL) and non-Hodgkin lymphoma (NHL). Engagement of CD3 by XmAb13676 activates T cells for highly potent and targeted killing of CD20-expressing tumor cells.

About XmAb14045

XmAb14045 is a tumor-targeted antibody that contains both a CD123 binding domain and a cytotoxic T-cell binding domain (CD3) in a Phase 1 clinical trial for the treatment of acute myeloid leukemia (AML) and other CD123-expressing hematologic malignancies. An XmAb Bispecific Fc domain serves as the scaffold for these two antigen binding domains and confers long circulating half-life, stability and ease of manufacture on XmAb14045. CD123 is highly expressed on AML cells and leukemic stem cells, and it is associated with poorer prognosis in AML patients. Engagement of CD3 by XmAb14045 activates T cells for highly potent and targeted killing of CD123-expressing tumor cells.

Sanofi and Regeneron Restructure Immuno-Oncology Collaboration for Discovery and Development Programs

On January 7, 2019 Sanofi (EURONEXT: SAN, NASDAQ: SNY) and Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) reported that they have restructured their global Immuno-oncology Discovery and Development Agreement for new immuno-oncology cancer treatments (Press release, Sanofi, JAN 7, 2019, View Source [SID1234532561]). The 2015 Agreement was scheduled to end in approximately mid-2020, and this revision provides for ongoing collaborative development of two clinical-stage bispecific antibody programs. This provides Sanofi increased flexibility to advance its early-stage immuno-oncology pipeline independently while Regeneron retains all rights to its other immuno-oncology discovery and development programs.
