Overview

We are a fully integrated commercial-stage innovative oncology company with an approved next-generation PD-1 inhibitor, LOQTORZI, and a pipeline that includes two mid-stage clinical candidates targeting liver, prostate, head & neck, colorectal and other cancers. Our strategy is to grow sales of LOQTORZI in NPC while advancing the development of our two pipeline candidates in combination with LOQTORZI, and additionally through strategic partnerships. We have global rights to both clinical-stage candidates and plan to execute ex-U.S. licensing deals as the clinical data supports such transactions.

We primarily operate in the United States and partner with companies that operate in other countries.

Product and Product Candidates

Our portfolio includes the following product and product candidates:

Oncology

On December 11, 2023 we announced that NCCN updated the clinical practice guidelines for NPC to include LOQTORZI as a preferred, category 1 first-line treatment option for adults with metastatic or recurrent locally advanced NPC when used in combination with cisplatin and gemcitabine. On November 26, 2024, NCCN made a further update to the clinical practice guidelines for NPC to specify that LOQTORZI is the only preferred category 1 first-line treatment option for adults with metastatic or recurrent locally advanced NPC when used in combination with cisplatin and gemcitabine. The guidelines also recommend LOQTORZI monotherapy as the only preferred treatment in subsequent lines of therapy with disease progression on or after a platinum-containing therapy.

Further evaluation of LOQTORZI is expected through multiple current and planned clinical studies by us and our partners. We have a post marketing commitment study active and enrolling patients in locations in the U.S. and Canada in order to further evaluate the efficacy of toripalimab in combination with chemotherapy (cisplatin and gemcitabine) in patients with advanced NPC (clinicaltrials.gov identifier# NCT06457503). Junshi Biosciences is currently enrolling in a multiregional Phase 3 clinical study evaluating the treatment of

LOQTORZI with its investigational anti-BTLA antibody in LS-SCLC (clinicaltrials.gov identifier# NCT06095583). INOVIO Pharmaceuticals, Inc. plans a randomized Phase 3 study of INO-3112 and toripalimab in locally advanced, high risk HPV16/18+ oropharyngeal squamous cell carcinoma. Cancer Research Institute is evaluating toripalimab in combination with ENB Therapeutics’ investigational agent ENB-003 in its Phase 2 trial titled, “Immunotherapy Platform Study in Platinum Resistant High Grade Serous Ovarian Cancer (IPROC)” (clinicaltrials.gov identifier# NCT04918186) that is being performed in collaboration with Canadian Cancer Trials Group. STORM Therapeutics, Ltd. is evaluating its METTL3 inhibitor STC-15 in combination with LOQTORZI in a Phase 1b/2 study (clinicaltrials.gov identifier# NCT06975293) for the treatment of non-small cell lung cancer and head and neck squamous cell carcinoma (“HNSCC”), and has plans for melanoma and endometrial cancer. On June 27, 2024, we entered into a license Agreement with Apotex, Inc. (“Apotex”), pursuant to which, we granted to Apotex an exclusive license under our rights to toripalimab to commercialize toripalimab within Canada (“Canada License Agreement”).

On February 4, 2026, we announced a clinical supply agreement with Janssen Research & Development, LLC, to evaluate tagmokitug in combination with pasritamig, a T-cell engaging bispecific antibody, in a Phase 1b clinical study in patients with metastatic castration-resistant prostate cancer. Under the terms of the clinical supply agreement, Janssen will provide pasritamig to us, and we will be the sponsor of the Phase 1b clinical trial. Janssen and us each retain all commercial rights to our respective compounds, including as monotherapy or as combination treatments. The pasritamig combination study is expected to initiate in the fall.

License Agreement with Junshi Biosciences

On February 1, 2021, we entered into the Collaboration Agreement with Junshi Biosciences for the co-development and commercialization of LOQTORZI, Junshi Biosciences’ anti-PD-1 antibody in the United States and Canada.

Under the terms of the Collaboration Agreement, we paid $150.0 million upfront for exclusive rights to LOQTORZI in the United States and Canada. We obtained the right to conduct all commercial activities of LOQTORZI in the United States and Canada. We have paid $25.0 million for the achievement of certain milestones, and we pay a royalty in the low twenty percent range on net sales of LOQTORZI. On June 27, 2024, we entered into the Canada License Agreement pursuant to which, we granted to Apotex an exclusive license under our rights to toripalimab to commercialize toripalimab within Canada. Apotex received Health Canada approval for LOQTORZI for the treatment of recurrent unresectable or metastatic nasopharyngeal cancer in October 2025.
