An Phase I Study of YY001 in Patients with Advanced Solid Tumors

NCT06228846 | Completed Phase 1

• 1 other identifier: 2021-YY001-CH1
• Study Type: interventional
• Target: 16
• Locations: 1 country
• Sites: 1

Brief Summary

The safety and tolerability of YY001 in the treatment of patients with advanced solid tumors were evaluated, and the possible dose-limiting toxicity (DLT) and the maximum tolerated dose (MTD) or recommended phase II clinical dose (RP2D) were observed.

Conditions

Advanced Solid Tumor

Outcome Measures

Primary Outcomes (3)

• Dose limiting toxicity

  The incidence and severity of adverse events (TEAE) during treatment were graded according to the National Cancer Institute Standard for Common Terminology for Adverse Events (NCI-CTCAE, v5.0)

  Up to 24 days after the initial drug administration

• Maximum tolerated dose

  In the dose increment stage, the highest dose whose estimated DLT rate is closest to the target DLT rate but does not exceed the upper bound of the equivalent interval of DLT rate is selected as MTD.

  Up to 24 days after the initial drug administration

• Recommended Dose for Phase II Clinical Studies (RP2D)

  The RP2D is defined as the dose level chosen by the sponsor (in consultation with the investigators) for phase II study, based on safety, tolerability, efficacy, PK, and PD data collected during the dose escalation study of YY001.

  Up to 24 days after the initial drug administration

Secondary Outcomes (2)

• Duration of Response(DoR)

  Up to approximately 24 months

• Overall Survival (OS)

  Up to approximately 24 months

You may not qualify if:

• \. The adverse reactions of previous antineoplastic therapy have not recovered to CTCAE 5.0 grade ≤1 (except for toxicities without safety risks judged by investigators, such as alopecia, grade 2 peripheral neurotoxicity, and hypothyroidism stable with hormone replacement therapy);
• \. Clinically symptomatic parenchymal or leptomeningeal metastases that were judged by the investigator to be ineligible for enrollment;
• \. Within 4 weeks before delivery for the first time received chemotherapy, radiation therapy, biological therapy and endocrine therapy, immune therapy, such as antitumor drugs, with the exception of the following situations:
