NCT05171790 | Unknown Phase 1

• 1 other identifier: QL1706-102
• Study Type: interventional
• Target: 419
• Locations: 1 country
• Sites: 1

Brief Summary

This a multi-center, open-label, non-randomized phaseⅠb trail. The purpose of this study was to evaluate the efficacy and safety of QL1706 in patients with advanced solid tumors and to investigate the immunogenicity and pharmacokinetic characteristics of QL1706.

Conditions

Advanced Solid Tumors

Outcome Measures

Primary Outcomes (1)

• objective response rate (ORR)

  ORR includes complete response (CR) and partial response (PR) cases. According to RECIST V1.1, the first appearance of PR or CR requires additional imaging to confirm the lesion at ≥4 weeks.

  up to 24 weeks

Secondary Outcomes (4)

• disease control rate (DCR)

  up to 24 weeks

• progression-free survival (PFS)

  From date of enrollment until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 24 months

• overall survival time (OS)

  From date of enrollment until the date of death from any cause, assessed up to 24 months

• adverse event (AE)

  up to 90 days after the last QL1706 injection is administered.

Study Arms (1)

QL1706 injection

EXPERIMENTAL

This clinical trail is a single arm study, all the patients that meet the entry criteria will receive treatment until disease progression occurs or meet other criteria for the discontinuation of treatment. QL1706 will be administered by intravenous infusion, 5 mg/kg, Q3W.

Drug: QL1706 injection

Interventions

QL1706 injection DRUG

5 mg/kg, IV, Q3w

Also known as: PSB205 injection

QL1706 injection

• Subjects agree to use effective contraceptive measures.Women who have not been pregnant or breastfeeding.
• Before the first use of the investigational drug, all the reversible toxicity of the previous antitumor therapy returned to ≤1 (according to CTCAE V5.0),Excluding any grade of hair loss and pigmentation, grade 2 or less peripheral sensory neuropathy, and other abnormalities that the investigator and/or sponsor assessed to outweigh the risk of toxicity.

You may not qualify if:

• Active autoimmune diseases that exist within 2 years prior to the first use of the investigational drug and require systemic treatment.
• There are known past grade 3 or 4 immune-related adverse events associated with antitumor immunotherapy.
• Symptomatic central nervous system (CNS) metastasis, pia metastasis or spinal cord compression due to metastasis prior to signing informed consent.
• Subjects with any of the following cardiovascular diseases that seriously endanger the safety of the subjects or affect the completion of the study
• Subjects with diseases that are planned to be treated with systemic corticosteroids or other immunosuppressive drugs during the study period
• Prior treatment with cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) inhibitor combined with programmed cell death protein-1 (PD-1) inhibitor, or CTLA-4 inhibitor combined with PD-L1 inhibitor.
• Had received chemotherapy, targeted therapy, biotherapy, endocrine therapy, immunotherapy and other anti-tumor treatments within 4 weeks before the first use of experimental drugs
• Subjects with positive antibodies to HIV;Treponema pallidum antibody positive;HBsAg positive patients with VIRAL DEoxy ribonucleic acid (HBV DNA) \>2000 IU/ mL or 10\^4 copy number/mL should receive antiviral therapy according to local treatment guidelines and be willing to receive antiviral therapy throughout the study period.Hepatitis C virus antibody positive and viral ribonucleic acid (HCV RNA) positive
