Brief Summary

This is a multicenter, open-label Phase Ib/II clinical study evaluating the safety, tolerability, pharmacokinetics (PK), and efficacy of the HS-20110 combination therapies in Patients with Advanced Colorectal Cancer. "Rolling 6" design would be used to conduct dose escalation part of this study. This study consists of phase Ib and phase II. After RP2D was determined in phase Ib, then a phase II study will be conducted to further evaluate the efficacy, safety, tolerability, and PK of the HS-20110 combination therapies in Patients with mCRC.

Conditions

CRC

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Males or females, aged ≥ 18 years.
• Participants with pathologically confirmed advanced Colorectal Cancer.
• Participants have at least 1 target lesion other than CNS lesions according to RECIST 1.1.
• MSI was tested to be non-MSI-H, and without BRAF V600E mutation.

You may not qualify if:

• Participants have received or are receiving the following treatment:
• Anti-tumor drugs within 14 days prior to the first dose of study treatment; any other IMPs or macromolecular anti-tumor drugs within 28 days prior to the first dose of study treatment.
• Local radiotherapy within 2 weeks prior to the first dose of study treatment; irradiation of more than 30% of bone marrow or extensive radiotherapy within 4 weeks prior to the first dose of study treatment.
• Major surgery within 4 weeks prior to the first dose of study treatment.
• Participants previously treated with drugs that are moderate to strong inhibitors or moderate to strong inducers of cytochrome P450 (CYP) 3A4, strong inhibitors or strong inducers of CYP2D6, P-glycoprotein (P-gp), breast cancer resistance protein (BCRP) or drugs with a narrow therapeutic range that are sensitive substrates of P-gp or BCRP within 7 days prior to the first dose of the IMP. Participants who need to receive these drugs during the study period should also be excluded.
• Current use of drugs known to prolong the QT interval or that may cause torsade de pointes. Participants who need to receive these drugs during the study period should also be excluded.
• Live vaccine or live-attenuated vaccine within 28 weeks prior to the first dose.
• Participants who have any Grade ≥ 2 residual toxicity according to Common Terminology Criteria for Adverse Events (CTCAE, version 5.0) from prior therapies (except alopecia and residual neurotoxicity).
• Inadequate bone marrow reserve or hepatic and renal functions.
• Participants with a history of severe allergy (such as anaphylactic shock), previous severe infusion reactions, or allergy to recombinant human or murine proteins.
• Participants who are allergic to any component of HS-20110 combination therapies.
