-- Management to Host Conference Call at 4:30 p.m. ET Today --

MONROVIA, Calif.--(BUSINESS WIRE)--Feb. 23, 2022-- Xencor, Inc. (NASDAQ:XNCR), a clinical-stage biopharmaceutical company developing engineered antibodies and cytokines for the treatment of cancer and autoimmune diseases, today reported financial results for the fourth quarter and full year ended December 31, 2021 and provided a review of recent business and clinical highlights.

“In 2021, we made significant decisions to advance our portfolio of internal XmAb^® drug candidates — the initiation of Phase 2 trials in prostate cancer with vudalimab, the entry into our second collaboration with Janssen, focused on plamotamab and additional CD28 bispecifics, as well as the decision to stop a Phase 1 program, vibecotamab. We are focused on using our resources on the most promising clinical-stage programs and on the next wave of additional reduced-potency cytokines, CD28 T cell engagers and 2+1 CD3 T cell engagers,” said Bassil Dahiyat, Ph.D., president and chief executive officer at Xencor. "We also maintained a strong financial position to support our portfolio, receiving over $200 million in collaboration upfront and milestone payments, as well as royalties from the first three XmAb medicines now marketed by our partners.”

Dr. Dahiyat continued, “Looking ahead, in 2022, we expect to present additional clinical data from our mid-stage development programs and initiate new studies for vudalimab and plamotamab. Also, we soon expect to initiate a Phase 1 study for XmAb819, our ENPP3 x CD3 bispecific antibody for renal cell carcinoma, which was engineered with our multivalent 2+1 format for greater tumor selectivity, an especially valuable tool for accessing challenging solid tumor antigens. We also plan to initiate new clinical trials for our lead cytokine, XmAb306, and to report data and initiate a new clinical study for our second engineered cytokine program, XmAb564. We remain excited by additional opportunities, both internally and together with our partners, to use our technologies and protein engineering capabilities to address challenging areas of biology and continually grow our portfolio.”

Recent Portfolio Highlights

• Vudalimab (PD-1 x CTLA-4): In November 2021, Xencor presented updated expansion cohort data from the Phase 1 study of vudalimab in patients with multiple types of advanced solid tumors at the SITC Annual Meeting. The results from the study indicate vudalimab was generally well tolerated and demonstrated activity in advanced prostate cancer, ovarian cancer, and multiple other tumor types and have informed Phase 2 development plans. The Company is currently enrolling a Phase 2 study in patients with metastatic castration-resistant prostate cancer (mCRPC), where vudalimab is being evaluated as a monotherapy or in combination with chemotherapy or a PARP inhibitor depending on the tumor’s molecular subtype. The Company plans to present initial data from the study in the second half of 2022. A second Phase 2 study will begin this year, evaluating vudalimab monotherapy in patients with advanced pelvic tumors, including clinically defined high-risk mCRPC and certain gynecologic malignancies.

• Plamotamab (CD20 x CD3): In December 2021, Xencor presented updated dose-escalation data from the Phase 1 study of plamotamab at the ASH Annual Meeting. Expansion cohorts are actively recruiting patients with DLBCL and FL and are dosing using the recommended Phase 2 regimen to further evaluate the safety and efficacy of plamotamab monotherapy. In 2022, subcutaneous administration of plamotamab will be incorporated into the study, and the Company plans to present data from the expansion cohorts in the second half of the year. The Company is currently opening clinical sites for the potentially registration-enabling Phase 2 study, evaluating plamotamab in combination with tafasitamab and lenalidomide, in patients with relapsed or refractory DLBCL.

• XmAb564 (IL2-Fc): XmAb564 is a potency-reduced IL2-Fc fusion protein targeting regulatory T cells, and it is being developed for patients with autoimmune disease. Xencor is conducting a Phase 1 study to evaluate the safety and tolerability of a single dose of XmAb564, administered subcutaneously in healthy adult volunteers. The Company plans to present tolerability, durability and biomarker data from the study in 2022 and plans to initiate a multiple-ascending dose study in select patient populations.

• XmAb306 (IL15/IL15Rα-Fc): XmAb306 is a potency-reduced IL15/IL15Rα-Fc fusion protein targeting NK and T cells for the treatment of patients with cancer, which Xencor is co-developing with Genentech, a member of the Roche Group. In November 2021, Xencor announced that XmAb306 promoted high levels of sustained NK cell expansion and evidence of peripheral effector T cell proliferation, in an ongoing Phase 1 dose-escalation study of XmAb306 in patients with advanced solid tumors. Additional studies of XmAb306 in combination with other therapeutic agents are being planned.

• Preclinical Data Presentations: New data from four preclinical-stage programs, including Xencor’s IL-12-Fc cytokine program (XmAb662), PD-L1 x CD28 bispecific antibody program, TGFβR2 bispecific antibody platform, and bispecific NK cell engager platform, were presented at the SITC Annual Meeting.

Progress Across Partnered Programs and New Partnerships

• Vir Biotechnology, Inc.: In 2021, Xencor recognized $52.2 million in royalty revenue under the Company’s agreement with Vir. Sotrovimab, an antibody that targets the SARS-CoV-2 virus and incorporates Xencor’s Xtend Fc domain for longer duration of action, is made available by Vir and its partner Glaxo Wellcome UK Limited and GlaxoSmithKline Biologicals S.A. under an emergency use authorization (EUA) from the U.S. FDA for the treatment of mild-to-moderate COVID-19 in high-risk adults and pediatric patients. Sotrovimab has also been granted a marketing authorization in the European Union, approved via Japan’s Special Approval for Emergency Pathway in Japan, and granted conditional, provisional, or temporary authorizations for the early treatment of COVID in 15 other countries.

• Janssen Biotech, Inc.: In the fourth quarter of 2021, Janssen selected a CD28 bispecific antibody candidate under the November 2020 collaboration agreement, and the Company earned a $5.0 million milestone payment. The first collaboration between Janssen and Xencor is focused on the discovery of XmAb bispecific antibodies against CD28, an immune co-stimulatory receptor on T cells, and an undisclosed prostate tumor target, for the potential treatment of patients with prostate cancer. Under the agreement, the Company has a right to access select, predefined agents from Janssen’s portfolio of clinical-stage drug candidates and commercialized medicines to evaluate potential combination therapies in prostate cancer with agents in the Company's own pipeline, subject to some limitations. Janssen has the same right with Xencor's portfolio to evaluate potential combination therapies in prostate cancer.

• Amgen Inc.: Amgen is enrolling patients with mCRPC in a Phase 1 study evaluating AMG 509 (STEAP1 x CD3), an XmAb 2+1 bispecific antibody. The XmAb 2+1 multivalent format enables higher binding capability for STEAP1 expressing cells. In February 2022, Amgen presented encouraging, preliminary data highlighting AMG 509’s pharmacodynamic activity of maximum prostate specific antigen (PSA) decline among 30 patients in the study, which provides an early signal of activity and potential validation for the capabilities of the XmAb 2+1 bispecific antibody format.

• Zenas BioPharma Ltd.: In November 2021, Xencor entered into a second product license agreement with Zenas and granted Zenas the exclusive worldwide rights to develop and commercialize obexelimab, which uses the XmAb Immune Inhibitor Fc Domain and targets CD19 with its variable domains, to inhibit the function of B cells. Xencor received a warrant to acquire additional equity in Zenas and is eligible to receive up to $470 million in milestone payments and tiered, mid-single digit to mid-teen percent royalties upon commercialization of obexelimab, dependent on geography.
