Heidelberg Pharma has dosed the first patient with HDP-102, an amanitin-based antibody-drug conjugate targeting CD37, in a Phase I study for relapsed or refractory non-Hodgkin lymphoma.
The multicenter trial will evaluate safety, tolerability, and pharmacokinetics across Moldova, Israel, and selected EU countries, with plans for dose escalation followed by expansion phases.
HDP-102 represents the company's second ATAC technology candidate to reach clinical development, following encouraging safety and efficacy data from HDP-101 in multiple myeloma.
Non-Hodgkin lymphoma affects over 550,000 new patients annually, with conventional chemotherapy achieving response rates above 50% but frequent relapses highlighting the need for more durable treatments.
