Study of HS-20105 for Injection in Patients With Advanced Solid Tumors.

Официальное название

Phase I Clinical Trial Evaluating the Safety, Tolerability, Pharmacokinetic and the Therapeutic Potential of HS-20105 for Injection in Patients With Advanced Solid Tumors.

Обзор

HS-20105 is a novel antibody-drug conjugate (ADC) targeting Trop-2. This first-in-human trial is aimed to assess the maximum tolerated dose (MTD) and dose limiting toxicity (DLT), to evaluate the pharmacokinetics (PK), safety and preliminary anti-tumor activity of HS-20105 in patients with advanced solid tumors.

Подробное описание

This is a multicenter, open-label Phase I clinical study evaluating the safety, tolerability, PK, and efficacy of HS-20105 in patients with advanced solid tumors. The study includes Phase Ia (dose escalation) and Phase Ib (dose extension). Phase Ia will conduct a dose escalation using the "Rolling 6" design in advanced solid tumor patients who have failed or are unable to tolerate standard treatment, to evaluate the safety, tolerability, PK characteristics, and efficacy of HS-20105. The subsequent Phase Ib study will be conducted in certain population to evaluate the preliminary efficacy of HS-20105 at different doses and in different populations.

Критерии участия

Критерии включения

The requirements for target lesions are: measurable lesions without local treatment such as irradiation, or with definite progress after local treatment, with the longest diameter ≥ 10 mm in the baseline period (in case of lymph nodes, the shortest axis ≥ 15 mm is required). Patients with only brain and/or bone lesions as target lesions will not be included.
• Fresh or archived tumor tissue samples need to be provided (fresh samples are preferred, and tumor tissue samples within 2 years before the first administration can be accepted; the sample type is formalin fixed, paraffin embedded \[FFPE\] tumor tissue block or FFPE slides).
• ECOG performance status was 0-1 and did not deteriorate in the previous 2 weeks.
• Estimated life expectancy greater than (>) 12 weeks.
• Reproductive-age women agree to use adequate contraception and cannot breastfeed while participating in this study and for a period of 6 months after the last dose. Likewise, men also consent to use adequate contraceptive method within the same time limit.
• Females must have the evidence of non-childbearing potential.
• Sign informed consent form.
