Phase I Study of Hemay102 in Patients With Advanced Solid Tumors

A Dose Escalation Phase I Clinical Study Evaluating the Safety, Tolerability, Pharmacokinetics, and Antitumor Efficacy of Hemay102 in Patients With Advanced Solid Tumors

This trial was a single-center, open-label, dose-increasing Phase I clinical study with subjects enrolled in patients with advanced solid tumors who failed standard treatment or who were unable to receive effective treatment. The trial is divided into two stages: dose escalation and dose extension.

Dose escalation:

A total of 7 dosage groups were set at this stage, which were 5 mg/m2, 10 mg/m2, 20 mg/m2, 40 mg/m2, 60 mg/m2, 90 mg/m2, and 120 mg/m2, respectively. Accelerated dosage titration was performed in the first 3 dose groups, 1 subject was enrolled in each group; the last 4 dose groups were perfromed into dosage groups by the principle of "3+3" dose increment rule, and the number of subjects enrolled in each group is 3 to 6 cases.

Dose extension:

According to the test results of the dose escalation phase, two extensions of MTD (tentative 60 mg/m2, 90 mg/m2) were selected for the expansion trial. Each dose level was planned to enroll 6 subjects (12 in total), subjects were administered once every 3 weeks (1 treatment cycle every 3 weeks), and received 4 treatment cycles in a row for Hemay102. Safety, tolerability, pharmacokinetic characteristics, and initial anti-tumor efficacy were evaluated.

Inclusion Criteria:

• Age ≥18 years old and ≤70 years old, male or female;
• A patient who has been confirmed by histology or cytology to have advanced or metastatic solid tumors (in the patients with locally advanced hepatocellular carcinoma or metastatic liver cancer, patients can be recruited by clinical diagnosis) and who have failed standard treatment or who are unable to receive/do not have effective treatment;
