Interleukin-10 Demonstrates Antitumor Activity in Patients With RCC

Interleukin-10 (AM0010) demonstrates antitumor activity, with an acceptable toxicity profile, in patients with renal cell carcinoma (RCC), according to a study published in the Journal of Clinical Oncology.¹

Researchers evaluated patients who were treated with AM0010 in a dose-escalation study, as well as a RCC dose-expansion cohort, with primary endpoints being safety and tolerability. Secondary endpoints were clinical activity and immune activation.

In total, 33 patients through the dose-escalation cohort and 18 patients through the dose-expansion cohort were examined. The treatment was tolerated in a heavily pretreated patient population.

Common treatment-related adverse events included anemia, fatigue, thrombocytopenia, fever, and injection site reactions, with grade 3 to 4 anemia or thrombocytopenia observed in 5 patients. Grade 3 to 4 nonhematopoietic treatment-related adverse events included rash and transaminitis in 5 of the patients in the dose-escalation cohort. Most treatment-related adverse events were transient or reversible.

AM0010 led to systemic immune activation with an elevation in immune-stimulatory cytokines, as well as a reduction in transforming growth factor beta in the serum.
