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

MONROVIA, Calif.--(BUSINESS WIRE)--Aug. 6, 2019-- 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.

• XmAb20717 (PD-1 x CTLA-4):A Phase 1 dose-escalation study in patients with advanced solid tumors began dosing patients in July 2018. Enrollment in dose-escalation cohorts is ongoing, and initial data are expected in the first half of 2020.

• XmAb22841 (CTLA-4 x LAG-3): In May 2019, the first patient was dosed in a Phase 1 study evaluating XmAb22841 as a monotherapy and in combination with pembrolizumab in patients with select advanced solid tumors.

• XmAb23104 (PD-1 x ICOS):In May 2019, the first patient was dosed in a Phase 1 study in patients with select advanced solid tumors.

Cytokines: Xencor uses its bispecific Fc domain and Xtend™ technology to engineer cytokines, which are immune signaling proteins, that have potency tuned to improve therapeutic index and have longer half-life.

• XmAb24306 (IL15/IL15Rα-Fc fusion protein): The Company will support Genentech's efforts to submit an IND application for this candidate, which is anticipated in the second half of 2019.

Partnered XmAb Programs: Xencor has eight licensing partnerships for XmAb technology. The most advanced program where the Company has licensed its technology is Alexion’s Ultomiris^®, which has received marketing authorizations for the treatment of adult patients with paroxysmal nocturnal hemoglobinuria (PNH) in the U.S. (December 2018), Japan (June 2019) and Europe (July 2019).

Corporate: In June 2019, Xencor announced the planned October 31, 2019 retirement of Paul Foster, M.D., Chief Medical Officer. As the Company searches for Dr. Foster’s successor, Xencor strengthened its senior management team in the second quarter with the appointments of Jeremy Grunstein, Ph.D., as vice president, business development, and Kirk Rosemark, as vice president, regulatory affairs and quality assurance.

Ultomiris^® is a registered trademark of Alexion Pharmaceuticals, Inc.

Second Quarter Ended June 30, 2019 Financial Results

Cash, cash equivalents and marketable securities totaled $626.1 million as of June 30, 2019, compared to $530.5 million at December 31, 2018. The increase reflects upfront proceeds of $135 million received in the first half of 2019 from the Genentech and Astellas collaborations, offset by cash used to fund operating activities in the first six months of 2019.

Total revenue for the second quarter ended June 30, 2019 was $19.5 million, which was primarily revenue recognized under the Astellas collaboration and a milestone and royalties earned from Alexion. Total revenue for the six months ended June 30, 2019 was $131.4 million and includes revenue earned from the Genentech and Astellas collaborations and the milestone and royalty revenue from Alexion. No revenue was reported for the same periods in 2018.

Research and development expenses for the second quarter of 2019 were $33.3 million, compared to $23.3 million for the same period in 2018. Total research and development expenses for the six months ended June 30, 2019 were $61.5 million, compared to $49.4 million for the same period in 2018. The increased research and development spending for the three and six months ended June 30, 2019 reflects increased stock-based compensation expense and additional spending on Xencor’s CD3 bispecific antibody and cytokine development candidates and technologies.

General and administrative expenses for the second quarter of 2019 were $5.8 million, compared to $5.0 million for the same period in 2018. Total general and administrative expenses for the six months ended June 30, 2019 were $11.3 million, compared to $9.5 million for the same period in 2018. The increased general and administrative spending for the three and six months ended June 30, 2019 reflects additional spending on intellectual property including patents and licensing and additional expenses related to personnel and professional services.

Non-cash, stock-based compensation expense for the six months ended June 30, 2019 was $15.2 million, compared to $9.4 million for the same period in 2018.

Net loss for the second quarter ended June 30, 2019 was $16.0 million, or $(0.28) on a fully diluted per share basis, compared to a net loss of $25.9 million, or $(0.46) on a fully diluted per share basis, for the same period in 2018. For the six months ended June 30, 2019, net income was $64.0 million, or $1.10 on a fully diluted per share basis, compared to a net loss of $55.4 million, or $(1.07) on a fully diluted per share basis, for the same period in 2018. The lower net loss reported for the three months ended June 30, 2019 over the same period in 2018 is primarily due to revenue from our Astellas and Alexion collaborations in 2019. The net income reported for the six months ended June 30, 2019 over the net loss reported for the same period in 2018 is primarily due to revenue recognized from our Genentech collaboration.

The total shares outstanding were 56,529,398 as of June 30, 2019, compared to 55,821,310 as of June 30, 2018.
