Brief Summary:
The study is being conducted to evaluate the safety and tolerability of HRS-4642 in patients with advanced solid tumors harboring KRAS G12D mutation.To estimate the maximum tolerated dose (MTD) and/or a biologically active dose (eg, recommended phase 2 dose [RP2D]) within investigated subject population groups

Condition or disease Intervention/treatment Phase
Advanced KRAS G12D Mutant Solid Tumors Drug: HRS-4642 Phase 1

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 108 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Intervention Model Description: Single arm study of HRS-4642
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Phase I Study to Evaluate the Safety ,Tolerability, and Pharmacokinetics of HRS-4642 in Patients With Advanced Solid Tumors Harboring KRAS G12D Mutation
Actual Study Start Date : September 15, 2022
Estimated Primary Completion Date : April 30, 2024
Estimated Study Completion Date : December 30, 2024

Arm Intervention/treatment
Experimental: HRS-4642

In Dose Escalation:

HRS-4642 will be injected QW. Six dose levels are preset.

In Dose Expansion:

1 to 2 dose cohorts will be selected for dose expansion stage.

In Indication Expansion:

Enrollment into the dose expansion cohorts may be from any eligible solid tumor type.

Drug: HRS-4642
HRS-4642 will be administrated per dose level in which the patients are assigned.

Primary Outcome Measures :
  1. Safety endpoints: adverse events(AEs), serious adverse events(SAEs). [ Time Frame: 24 months ]
    Assess safety and tolerability of HRS-4642 by way of adverse events (CTCAE v5.0).

  2. Dose Limited Toxicity(DLT) [ Time Frame: from day 1 to Day 21 ]
    A DLT is defined as any event meeting the DLT criteria occurring within 21 days of first dose on Cycle 1 Day 1 (C1D1), excluding toxicities clearly related to disease progression or intercurrent illness

  3. Maximum tolerated dose (MTD) [ Time Frame: From Day 1 to Day 21 ]
    Incidence and category of dose limiting toxicities (DLTs) during the first 21-day cycle of HRS-4642 treatment.

  4. RP2D [ Time Frame: 24 months ]
    RP2D will be determined on the basis of evaluation on safety, PK, efficacy data in dose escalation and dose expansion stages.

Secondary Outcome Measures :
  1. Number of Participants With Abnormal Laboratory Values [ Time Frame: 24months. ]
  2. Number of subjects with clinically significant changes in ECOG, vital signs and physical examination. [ Time Frame: 24months. ]
  3. Number of subjects with changes on ECG. [ Time Frame: 24months. ]
  4. Efficacy endpoints: Overall response rate (ORR). [ Time Frame: 24months. ]
    Evaluated by RECIST v1.1.

  5. Efficacy endpoints: Duration of response (DoR). [ Time Frame: 24 months. ]
    Evaluated by RECIST v1.1

  6. Efficacy endpoints: Disease control rate (DCR). [ Time Frame: 24months. ]
    Evaluated by RECIST v1.1.

  7. Efficacy endpoints: Progression free survival (DoR). [ Time Frame: 24months. ]
    Evaluated by RECIST v1.1.

  8. Efficacy endpoints: overall survival (OS). [ Time Frame: 24minths ]
    Evaluated by RECIST v1.1

  9. Cmax. [ Time Frame: 24 months. ]
    Maximal plasma concentration.

  10. Tmax. [ Time Frame: 24 months ]
    Time to Cmax.

  11. AUC. [ Time Frame: 24 months. ]
    Area under the plasma concentration-time curve.

  12. t1/2. [ Time Frame: 24 months. ]
    Terminal-phase elimination half-life.

  13. Vz/F. [ Time Frame: 24 months. ]
    Apparent volume of distribution during terminal phase after non-intravenous administration.

  14. CL/F. [ Time Frame: 24 months. ]
    Apparent total clearance of the drug from plasma after oral administration.
