Xencor Reports Third Quarter 2020 Financial Results

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

MONROVIA, Calif.--(BUSINESS WIRE)-- Xencor, Inc. (NASDAQ:XNCR), a clinical-stage biopharmaceutical company developing engineered monoclonal antibodies for the treatment of cancer and autoimmune diseases, today reported financial results for the third quarter ended September 30, 2020 and provided a review of recent business and clinical highlights.

“In 2020, we have reported advances for multiple programs in our clinical pipeline. Monjuvi^® became the second drug with XmAb^® Fc technology to receive marketing approval in the United States, and we reported initial clinical results from multiple programs across our portfolio of XmAb bispecific antibodies in oncology. In the coming weeks, we will present additional clinical data from some of these programs, including updated results from the Phase 1 studies of XmAb20717 at SITC, and vibecotamab at ASH,” said Bassil Dahiyat, Ph.D., president and chief executive officer at Xencor. “We also continue to leverage our protein engineering expertise to rapidly generate drug candidates with our XmAb bispecific Fc domains, in order to advance a range of innovative technologies and molecules, and at SITC next week, we will be presenting new preclinical data from our B7-H3 x CD28 and PD-1 x TGFβR2 bispecific antibody programs, as well as our IL-12-Fc program.”

Dr. Dahiyat continued, “Looking ahead to next year, we are on track to initiate a Phase 1 study of XmAb27564, our IL-2 cytokine for autoimmune disease, in healthy volunteers in early 2021. Subject to potential COVID-19 impacts, we also plan to advance clinical studies across all our CD3 programs including vibecotamab, plamotamab, tidutamab and XmAb30819, which is our first XmAb 2+1 bispecific antibody and targets the underexplored tumor target ENPP3.”

COVID-19 Business Update

Clinical Studies: The pandemic did not significantly disrupt patient enrollment to Xencor’s six ongoing clinical studies during the third quarter of 2020. Manufacturers that provide the Company’s drug supply are currently experiencing critical shortages of material used in their manufacturing processes. Xencor has sufficient supplies of drug material to continue conducting ongoing studies without interruption; however, delays are expected in the development timelines for the preclinical XmAb30819 program. Timelines for additional early-stage programs and ongoing clinical programs could be affected if the supply interruption extends longer than current estimates.

Workforce and Research Operations: During the third quarter, Xencor continued to require non-laboratory employees to work remotely.

Licensing and Partnerships: Xencor is monitoring potential impacts to partnership revenues, which are primarily milestone payments and royalties. There was no impact during the third quarter as the Company earned revenue from its partners and collaborators including Alexion, MorphoSys and Omeros. If the pandemic affects the sales or clinical and regulatory progress of partnered programs, Xencor’s revenue could be adversely affected in the future.

Recent Business and Clinical Highlights

Tidutamab (SSTR2 x CD3): In October, the Company presented initial dose-escalation data from the ongoing Phase 1 study in patients with neuroendocrine tumors (NET). Tidutamab was generally well tolerated at the recommended dose identified for the expansion portion of the study, a 0.3 mcg/kg priming dose and subsequent 1.0 mcg/kg repeated doses. Peripheral blood biomarkers indicated tidutamab induced acute and sustained T-cell activation at this dose, and a dose-dependent increase in proliferation and activation markers of CD8+ T cells was observed, which is consistent with tidutamab’s mechanism of action. The best overall response was stable disease in the analysis to describe clinical activity (n=14), and the median duration of treatment was approximately seven months. Completion of enrollment and longer follow-up are required to evaluate progression-free survival and the clinical utility of tidutamab for patients with NET. Xencor plans to initiate an additional clinical study in patients with Merkel cell carcinoma and small cell lung cancer, SSTR2-expressing tumor types known to be responsive to immunotherapy, in early 2021.

New Clinical Collaboration: In September, Xencor and MD Anderson entered a strategic collaboration to design and execute new investigator-sponsored clinical studies with Xencor’s portfolio of XmAb drug candidates, including novel bispecific antibodies and engineered cytokines. Xencor is committing $10 million in funding and supporting these studies over an initial five-year term.

Select Internal Programs: Xencor will present updated data from the vibecotamab and XmAb20717 programs, as well as data from several preclinical-stage programs, at upcoming scientific and medical meetings.

• Vibecotamab (CD123 x CD3): Updated results from the ongoing Phase 1 study in patients with acute myeloid leukemia will be presented at the 62nd American Society of Hematology Annual Meeting in December 2020. Patient enrollment continues in this study, and Xencor plans to initiate additional clinical studies evaluating vibecotamab in 2021.

• Plamotamab (CD20 x CD3): Patient enrollment continues in the Phase 1 study in non-Hodgkin lymphoma and chronic lymphocytic leukemia, with planned expansion cohorts expected to open in 2021. In addition, operational preparation for a Phase 2 monotherapy trial in diffuse large B-cell lymphoma (DLBCL) is underway, as well as for a Phase 2 combination therapy study.

• XmAb20717 (PD-1 x CTLA-4): Updated results from the ongoing Phase 1 study in patients with advanced solid tumors will be presented at the 35th Annual Meeting of the Society for Immunotherapy of Cancer (SITC) in November 2020. The study is currently enrolling patients with renal cell carcinoma to an expansion cohort and continues to enroll patients in additional dose-escalation cohorts. Expansion cohorts for patients with melanoma, advanced non-small cell lung cancer, prostate cancer, and other cancers without approved checkpoint therapies are fully enrolled.

• New data from three preclinical-stage programs, including the IL-12-Fc cytokine program, the CD28 bispecific antibody platform, and the PD-1 x TGFβR2 bispecific antibody program, will also be presented at the SITC Annual Meeting in November 2020.

Select Partnered Programs: Xencor’s partners expand the use of XmAb technology by providing late-stage development capabilities, successful track records of developing or commercializing programs or have programs for potential combination with Xencor’s bispecific antibody or cytokine drug candidates. Additionally, the plug-and-play nature of XmAb technologies enables selective access for licensees with limited effort or resources by Xencor.

• Monjuvi^® (MorphoSys): Monjuvi is a CD19-directed cytolytic antibody indicated in combination with lenalidomide as a second-line treatment option for the treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL). Tafasitamab, which was engineered with an XmAb Cytotoxic Fc Domain, was created at Xencor and is the second product with Xencor’s XmAb technology to be approved by the FDA. Upon Monjuvi’s approval in July, Xencor earned a $25 million milestone payment from MorphoSys under the license agreement between the companies and is eligible to receive royalties on worldwide net sales in the high-single to low-double digit percent range, as well as additional development, regulatory and sales milestone payments. The European Marketing Authorization Application for tafasitamab is currently under review, and MorphoSys expects a decision in the second half of 2021.

• Ultomiris^® (Alexion): Alexion’s Ultomiris uses Xtend™ technology for longer half-life. In September, Japan’s Ministry of Health, Labour and Welfare approved Ultomiris for adults and children with atypical hemolytic uremic syndrome (aHUS). Ultomiris previously has received marketing authorizations from regulatory agencies in the U.S., Europe and Japan for the treatment of adult patients with paroxysmal nocturnal hemoglobinuria (PNH) and in the U.S. and Europe for aHUS. In addition to evaluating Ultomiris in a broad late-stage development program, Alexion is conducting a randomized, controlled Phase 3 study in adults with COVID-19 who are hospitalized with severe pneumonia or acute respiratory distress syndrome. Xencor is eligible to receive additional sales-based milestone payments and a low single-digit royalty on net sales of Ultomiris.

• VIR-7831 and VIR-7832 (Vir Biotechnology): Vir has non-exclusive access to Xencor’s Xtend Fc technology to extend the half-life of VIR-7831 and VIR-7832, novel antibodies that Vir is investigating as potential treatments for patients with COVID-19, as well as prophylactic use against infection from the virus. Vir has commenced a Phase 3 clinical study of VIR-7831 for the early treatment of COVID-19 patients who are at high risk of hospitalization; Vir plans to initiate a clinical study of VIR-7832 in the near future. Xencor is eligible to receive royalties on the net sales of approved products in the mid-single digit percent range.

• Omeros Corporation: In August, Xencor entered into a technology license agreement providing Omeros a non-exclusive license to its Xtend Fc technology, an exclusive license to apply Xtend technology to an identified antibody and options to apply Xtend technology to three additional antibodies. Omeros is responsible for all development and commercialization activities for all target candidates. Pursuant to these licenses, the Company received an upfront payment of $5.0 million and is eligible to receive development, regulatory and sales milestone payments for each product incorporating the selected antibodies. In addition, the Company is eligible to receive a royalty in the mid-single digit percent range on net sales of commercialized products.
