AlloNK® + Anti-CD20 Monoclonal Antibodies in Non-Hodgkin Lymphoma

Our ongoing Phase 1/2 clinical trial (ClinicalTrials.gov Identifier: NCT04673617) is assessing the safety and clinical activity of AlloNK® alone and in combination with the anti-CD20 monoclonal antibody, rituximab. The study is enrolling patients with relapsed or refractory B-cell non-Hodgkin lymphoma (NHL) who have progressed beyond two or more prior lines of therapy.

AlloNK® + Acimtamig (AFM13) in CD30-Positive Lymphomas

Artiva and Affimed have entered into a strategic collaboration to jointly develop, manufacture, and commercialize a combination therapy comprised of Artiva’s AlloNK®, and Affimed’s Innate Cell Engager (ICE®) acimtamig (previously known as AFM13) for the treatment of patients with relapsed/refractory CD30-positive lymphomas. The LuminICE-203 study (ClinicalTrials.gov Identifier: NCT05883449) is recruiting patients with r/r classical Hodgkin lymphoma and an exploratory arm in r/r PTCL.

AB-201: HER2 CAR-NK

AB-201 is our clinical-stage CAR-NK cell therapy candidate targeting HER2-positive solid tumors. We and our partner, GC Cell, are initiating the clinical evaluation of AB-201. The studies will assess AB-201 safety and efficacy in HER2+ breast and gastric/GEJ carcinomas. AB-201 HER2 CAR-NK uses a novel, high affinity HER2-directed antibody converted to Artiva’s proprietary CAR structure and expression of IL-15 for improved cellular persistence. AB-201 cell products maintain high expression of CD16, as well as other activating innate cell tumor engaging receptors, enabling the potential for dual targeting therapeutic approaches via monoclonal antibody combinations. The resulting CAR-NK is manufactured at large scale and cryopreserved in infusion-ready media to enable repeat clinical administrations in the outpatient setting.

AB-205 CD5-Directed CAR-NK

AB-205 has been developed preclinically by Artiva’s strategic partner, GC Cell, for the treatment of CD5+ lymphomas of T-cell origin. AB-205 is currently in IND-enablement studies.

Artiva and Affimed have entered into a strategic collaboration to jointly develop, manufacture, and commercialize a combination therapy comprised of AlloNK® and Affimed’s Innate Cell Engager (ICE®) acimtamig (previously known as AFM13). The clinical agreement follows the parties’ previous two-year preclinical collaboration to assess combining elements of the companies’ respective platforms in the generation of targeted, off-the-shelf allogeneic NK cell therapies. As part of the collaboration, the companies evaluated the combination of acimtamig and AlloNK in various preclinical models and generated data that supports development of a co-administered combination therapy.

Expanded Access Policy

Artiva does not currently have an expanded access program for our investigational products. Expanded access, also known as compassionate use, is a potential pathway for a patient with an immediately life-threatening condition or serious disease to gain access to an investigational drug for treatment outside of clinical trials when no comparable or satisfactory alternative therapy options are available.We are focused on enrolling and conducting the clinical trials necessary to bring innovative, safe, and effective products to patients as quickly as possible. Participation in one of our clinical trials is the only way to access Artiva’s investigational products at this time. We encourage patients and healthcare providers interested in our investigational products to learn more about our ongoing studies by visiting Artiva Clinical Studies.

Collaborations and partnerships are key to advancing, accelerating, and accessing life-saving therapies.
