CytomX Therapeutics, Inc. (Nasdaq: CTMX), a pioneer in the development of masked, conditionally activated biologic treatments, revealed that the initial patient has received a dose of CX-801 as a monotherapy in a Phase 1 clinical trial (NCT06462794) targeting solid tumors. CX-801 is a dually-masked interferon alpha-2b PROBODY® cytokine, which may offer extensive utility in both immune-oncology responsive and non-responsive (cold) tumors.

The Phase 1 dose escalation trial of CX-801 aims to assess its safety profile and early indicators of clinical activity as a standalone treatment and in conjunction with Merck’s (referred to as MSD outside the US and Canada) anti-PD-1 therapy, KEYTRUDA® (pembrolizumab). During the dose escalation phase, the study will recruit patients with certain solid tumors, such as advanced melanoma, renal cell carcinoma, and head and neck squamous cell carcinoma. The goal is to determine whether to proceed to Phase 1b with specific dose expansion cohorts based on the indications.
"Interferon-alpha-2b is a robust immune-modulating cytokine that has shown clinical activity in various cancer types, including metastatic melanoma, renal cancer, and bladder cancer. However, its clinical utility has been limited due to significant toxicities when used systemically. CX-801 leverages CytomX’s leading-edge conditional activation platform to retain its potency while broadening the therapeutic index of interferon. This innovation has the potential to make it a critical component of immuno-oncology combination therapies," explained Wayne Chu, M.D., chief medical officer at CytomX Therapeutics.
