Summary

This is a protocol for expanded access use of nogapendekin-alfa inbakicept (NAI) in participants with lymphopenia induced by chemotherapy, immunotherapy, and/or radiation therapy who may benefit from its use, and who are ineligible to participate in a clinical trial using NAI. The primary objective of this protocol is to evaluate the reversal and maintenance of absolute lymphocyte count (ALC) with NAI.

Detailed description

It is now well established that patients undergoing standard of care chemotherapy, immunotherapy, and/or radiation therapy sustain the adverse effects of these agents with a reduction in lymphocyte count (lymphopenia), and a significant clinical effect of reduced overall survival across all tumor types. Severe lymphopenia is defined as absolute lymphocyte count (ALC) \< 1,000 lymphocytes per microliter as determined by the complete blood count (CBC) differential analysis. No current therapy exists for the regeneration and proliferation of the most important immune cells in the blood compartment responsible for cytotoxicity of tumor cells, the lymphocytes. Expanded access of NAI for the treatment of lymphopenia addresses an unmet medical need, since no therapy is currently approved to reverse a low lymphocyte count and maintain lymphocytes within the normal range. By offering patients the ability to treat lymphopenia, the potential exists of increasing overall survival.

Conditions
