Cancer is the second leading cause of death, and the burden of cancer continues to grow globally. Research on the efficacy of combined administration of herbal medicine and anticancer drugs is also increasing. SH003 is a new herbal medicine composed of Astragalus membranaceus , Angelica gigas , and Trichosanthes kirilowii . SH003 alone up to 4800 mg daily was found to be safe. Preclinical studies have shown SH003 to have a synergistic effect with coadministration of anticancer drugs. This study aimed to determine the maximum tolerated dose of SH003 combined with docetaxel in patients with lung or breast cancer. Methods: This is an open-label, dose-escalation study to evaluate the safety of SH003 combined with docetaxel. Patients with lung or breast cancer will be recruited. The participants will be divided into 3 groups based on SH003 daily dose (2400, 3600, and 4800 mg); the medication will be taken orally for 21 days. The traditional 3 + 3 design will be adopted for the dose escalation. Dose-limiting toxicities are defined as grade 3 or 4 adverse events according to the Common Terminology Criteria for Adverse Events. The highest dose at which no more than 1 of the 6 patients experience dose-limiting toxicity will be determined as the maximum tolerated dose of SH003 combined with docetaxel. Discussion: This study investigates the safety of SH003 when combined with docetaxel. The results of this study will provide a safe dose range for conducting therapeutic exploratory trials.
