An Open-label, Multicenter, Phase II Clinical Study to Evaluate HRS-7058 in Patients With Pancreatic Cancer

An Open, Multicenter, Phase II Clinical Study to Evaluate the Efficacy and Safety of HRS-7058 in Patients With Locally Advanced or Metastatic Pancreatic Cancer Harboring KRAS G12C Mutations Who Have Failed Prior Systemic Therapy.

This is a multicenter, open-label, single-arm, phase II cilinical trial designed to evaluate the efficacy and safety of the KRAS G12C selective inhibitor HRS-7058 in patients with KRAS G12C-mutated advanced pancreatic cancer who had failed 1-2 lines of previous systemic therapy.

Inclusion Criteria:

1. Informed consent was obtained from all participants before participating in the study.
2. Age from 18 to 75 years old (including both ends), regardless of gender;
3. Patients with locally advanced unresectable, recurrent unresectable or metastatic pancreatic cancer, and adenocarcinoma confirmed by cytology or histological pathology;
4. Participants had received at least one previous systemic therapy
5. At least one measurable lesion according to RECIST v1.1;
6. ECOG PS score 0 or 1;
7. The expected survival time was more than 3 months.
8. They were able to swallow medications and were able to adhere to trial and follow-up procedures.
9. Adequate bone marrow and organ function within 7 days before the first dose (no use of blood components and/or cell growth factors within 14 days before starting study treatment;
10. Women of childbearing potential had to agree to abstain from sexual intercourse (heterosexual intercourse) or to use a highly effective method of contraception from the time they provided informed consent until 30 days after the last dose of the trial drug. A blood test for human chorionic gonadotropin (HCG) had to be negative within 7 days before starting study treatment and she had to be nonlactating (if a serum pregnancy test was positive, pregnancy was ruled out and enrollment was confirmed after discussion with the sponsor). Men whose partner was a woman of childbearing potential had to agree to abstain from sex or to use a highly effective method of contraception from the time they provided written informed consent until 30 days after the last dose of the trial drug. Male patients also had to agree not to donate sperm during the same period
