Arcus Biosciences Advances Cancer Treatment with AB801 Study

Arcus Biosciences ((RCUS)) announced an update on their ongoing clinical study.

Arcus Biosciences is conducting a Phase 1/1b study titled A Study of AB801 Monotherapy and Combination Therapy in Participants With Advanced Malignancies. The study aims to evaluate the safety and tolerability of AB801, a drug for advanced cancers, and to determine the recommended dose for further research. This study is significant as it could lead to new treatment options for patients with limited alternatives.

The intervention being tested is AB801, administered orally either as a monotherapy or in combination with Docetaxel for certain participants. AB801 is designed to treat advanced malignancies, potentially offering a new therapeutic avenue.

The study is interventional, non-randomized, and follows a sequential model without masking. Its primary purpose is treatment-focused, aiming to establish a safe dosage for AB801.

The study began on January 19, 2024, with a primary completion date yet to be announced. The latest update was submitted on July 30, 2025, indicating ongoing progress in the study.

This update could positively influence Arcus Biosciences’ stock performance by demonstrating progress in their drug development pipeline. Investor sentiment may be buoyed by the potential for a new cancer treatment, although competition in the oncology sector remains fierce.

The study is currently recruiting, and further details are available on the ClinicalTrials portal.
