Kiromic BioPharma, Inc. (KRBP) is a clinical-stage biotherapeutics company that develops cell therapies targeting solid tumors using non-engineered and engineered allogeneic Gamma Delta T (GDT) cell technologies and its proprietary DIAMOND AI target discovery platform; core product candidates include Deltacel (KB-GDT-01), in Phase 1 trials for non-small cell lung cancer in combination with low-dose radiation, Procel, and Isocel, each addressing unmet needs in immuno-oncology for solid tumors representing 90% of cancers. The company, founded in 2006 and headquartered in Houston, Texas, focuses on the United States market with investigational new drug applications planned for additional GDT-based trials. In March 2025, Kiromic filed for Chapter 7 bankruptcy protection, leading to an asset purchase agreement in April 2025 with Immunocell Therapeutics Inc., one of its investors, to acquire key assets including ongoing clinical trials such as the recruiting Deltacel Phase 1 study with 48 estimated participants set for completion in 2026; this expedited sale aims to minimize disruption to operations and preclinical programs amid prior pipeline prioritization of off-the-shelf allogeneic therapies announced in 2022.
