Xencor, Inc. is a clinical-stage biopharmaceutical company dedicated to developing innovative antibody therapeutics for the treatment of cancer, autoimmune, and other serious diseases. With a strong focus on engineering advanced protein technologies, Xencor has built an impressive pipeline of drug candidates that leverage its proprietary XmAb® platform. As the company navigates the intricate landscape of biopharmaceutical development, its unique approach and strategic priorities have positioned it as a promising player in the rapidly evolving healthcare sector.
Business Overview and History
Xencor was incorporated in California in 1997 and later reincorporated in Delaware in 2004. The company's core focus is on engineering antibody Fc domains, the constant regions of antibodies that interact with various components of the immune system. By utilizing its XmAb technology platform, Xencor has been able to design and develop a diverse portfolio of drug candidates with improved properties, such as enhanced immune inhibition, increased cytotoxicity, extended half-life, and novel multispecific formats.
Over the years, Xencor has steadily expanded its pipeline, with several of its XmAb-based product candidates currently in clinical development for the treatment of cancer and autoimmune diseases. The company's approach to protein design includes engineering Fc domains, which are the parts of antibodies that interact with multiple segments of the immune system and control antibody structure.
In 2013, Xencor reached a significant milestone when its common stock began trading on the Nasdaq Global Market. Since then, the company has experienced periods of operating losses as it has devoted substantial resources to fund its research and development programs. Despite these challenges, Xencor has made progress in developing its technology platform and advancing its pipeline of antibody product candidates.
Throughout its history, Xencor has entered into various collaboration and licensing agreements, which have provided funding and access to complementary resources to support its drug development efforts. Notably, three marketed XmAb medicines have been developed using Xencor's protein engineering technologies, representing important milestones for the company.
In 2024, Xencor announced a strategic realignment of its pipeline to focus on XmAb drug candidates that leverage the company's protein engineering strengths and reduce exposure to biological uncertainties. This decision was likely made in response to the challenges the company had faced in advancing its product candidates through clinical development.

As of the company's most recent fiscal year ended December 31, 2024, Xencor reported total revenue of $110.49 million, a decrease from the $174.62 million reported in the previous year. This decline was primarily driven by lower milestone and licensing revenue, partially offset by an increase in royalty income. The company's net loss for the year was $232.62 million, or $3.58 per diluted share, compared to a net loss of $133.13 million, or $2.20 per diluted share, in the prior year.
Despite the reported net losses, Xencor maintained a strong balance sheet, with $706.70 million in cash, cash equivalents, and marketable securities as of December 31, 2024. The company's current ratio, a measure of liquidity, stood at 6.61, indicating a robust ability to meet its short-term obligations.
Xencor's research and development expenses for the year ended December 31, 2024, were $227.69 million, a decrease from the $253.60 million reported in the previous year. This reduction in R&D spending reflects the company's strategic prioritization of its core pipeline programs and a shift in resource allocation.
For the most recent quarter (Q4 2024), Xencor reported revenue of $52.79 million, representing a significant year-over-year increase of 293.4% compared to Q4 2023. The net loss for the quarter was $45.60 million. Operating cash flow for the full year 2024 was negative $202.19 million, while free cash flow was negative $211.70 million.
Xencor primarily sells in the United States market, positioning itself as a small-cap company within the biotechnology industry. The industry has experienced a compound annual growth rate (CAGR) of approximately 10-15% over the past five years, indicating a favorable growth environment for companies like Xencor.
Liquidity
Xencor's strong balance sheet and liquidity position provide the company with significant financial flexibility to fund its ongoing research and development activities. With $706.70 million in cash, cash equivalents, and marketable securities, Xencor has ample resources to support its pipeline advancement and strategic initiatives. The company's current ratio and quick ratio both stand at 6.61, demonstrating its ability to comfortably meet short-term obligations and navigate potential financial challenges in the biopharmaceutical development landscape.
As of December 31, 2024, Xencor reported cash and cash equivalents of $40.88 million. The company also maintains a $0.40 million letter of credit that is collateralized by a money market account, classified as restricted cash. Xencor's debt-to-equity ratio is 0.34, indicating a relatively low level of leverage.
Recent Developments and Outlook
In 2024, Xencor announced several important clinical and strategic advancements. The company initiated first-in-human studies for its XmAb541 and XmAb942 programs, both of which have the potential to address significant unmet medical needs in oncology and autoimmune diseases, respectively.
Additionally, Xencor regained exclusive worldwide rights to plamotamab, its CD20 x CD3 bispecific antibody, from its previous collaboration with Johnson & Johnson. The company plans to initiate a Phase 1b/2a proof-of-concept study for plamotamab in rheumatoid arthritis, leveraging the promising data observed in the ongoing lymphoma program.
The company also announced the development of XmAb657, a potent and potentially long-acting CD19 x CD3 bispecific antibody, which is being evaluated for the treatment of autoimmune diseases. This expansion into the autoimmune space aligns with Xencor's strategic focus on leveraging its XmAb technology to address high unmet needs in this therapeutic area.
Looking ahead, Xencor remains committed to advancing its pipeline of XmAb-based drug candidates, with several key milestones expected in 2025, including the initiation of a Phase 2 study for XmAb942 in ulcerative colitis and the commencement of the Phase 1b/2a study for plamotamab in rheumatoid arthritis.
Xencor's oncology pipeline includes several T-cell engaging bispecific antibody drug candidates in clinical development. XmAb819, a first-in-class, tumor-targeted, T-cell engaging XmAb 21 bispecific antibody, is being developed for patients with clear cell renal cell carcinoma (ccRCC). Initial evidence of anti-tumor activity has been observed in dose-escalation cohorts in the ongoing Phase 1 study. XmAb541, another first-in-class bispecific antibody, is in development for patients with Claudin-6 (CLDN6) expressing tumor types, including ovarian cancer. XmAb808, a tumor-selective, co-stimulatory CD28 bispecific antibody, is being evaluated in combination with pembrolizumab in patients with advanced solid tumors.
In the autoimmune disease space, Xencor is advancing XmAb942, a monospecific anti-TL1A antibody, for the treatment of inflammatory bowel disease (IBD). The company initiated dosing of healthy volunteers in the first-in-human study of XmAb942 in Q4 2024 and expects initial single-ascending dose data from the Phase 1 study in the first half of 2025.
