Xencor Reports Second Quarter 2019 Financial Results
Xencor, Inc. (NASDAQ: XNCR), a clinical-stage biopharmaceutical company developing engineered monoclonal antibodies for the treatment of cancer, autoimmune diseases, asthma and allergic diseases, today reported financial results for the second quarter ended June 30, 2019 and provided a review of recent business and clinical highlights.
“Over the last two years, Xencor has initiated six Phase 1 clinical studies evaluating XmAb bispecific antibodies—both T cell engagers and tumor microenvironment (TME) activators—in patients with many types of advanced cancers, and we have also entered into strategic collaborations to advance select programs with our partners,” said Bassil Dahiyat, Ph.D., president and chief executive officer at Xencor. “We anticipate several initial data presentations from these programs in the second half of 2019 and first half of 2020, and our strong financial position supports our broad pipeline and research into novel antibodies and cytokines engineered with XmAb bispecific technologies.”
Dr. Dahiyat added, “In the second quarter, we reopened the Phase 1 study of XmAb14045 to enrollment, and patients have since begun treatment under the amended protocol. We also advanced our second and third TME activating bispecific antibodies into Phase 1 clinical studies. TME bispecific antibodies are designed with tuned dual checkpoint or checkpoint-agonist mechanisms to generate anti-tumor immune responses in a targeted manner. Finally, we continued to strengthen our senior leadership with appointments in business development and regulatory affairs.”
Recent Business and Clinical Highlights and Anticipated Upcoming Milestones
CD3 Bispecific Antibodies: Xencor's initial bispecific antibody programs are tumor-targeted antibodies that contain both a tumor antigen binding domain and a cytotoxic T-cell binding domain (CD3). These bispecific antibodies activate T cells for highly potent and targeted killing of malignant cells.
- XmAb14045 (CD123 x CD3): Clinical sites participating in the Phase 1 study in patients with relapsed/refectory acute myeloid leukemia have resumed enrollment, and in early July the first patient was dosed under the study’s amended protocol. Amendments to the protocol included guidance on the monitoring and clinical management of cytokine release syndrome.
- XmAb13676 (CD20 x CD3): A Phase 1 dose-escalation study began dosing patients with B-cell malignancies in February 2017. Enrollment in dose-escalation cohorts is ongoing, and initial data are expected in the fourth quarter of 2019.
- XmAb18087 (SSTR2 x CD3): A Phase 1 dose-escalation study began dosing patients with neuroendocrine tumors or gastrointestinal stromal tumors in February 2018. Enrollment in dose-escalation cohorts is ongoing, and initial data are expected in the first half of 2020.
Tumor Microenvironment (TME) Activating Bispecific Antibodies: Xencor's bispecific pipeline includes a suite of TME activators that engage multiple, different targets, such as T-cell checkpoint or agonist receptors. Xencor’s TME activators are designed to promote tumor-selective T-cell activation.
