Brief Summary

This is a multicenter, open-label, dose-escalation, dose-expansion, and cohort-expansion Phase I/II clinical study to evaluate safety, tolerability, pharmacokinetics, antitumor efficacy and to determine the maximum tolerated dose (MTD) and recommended Phase 2 doses (RP2D) of cisplatin micelle injection in patients with advanced malignant solid tumors. This study is divided into two stages, the first stage (stage I) is the dose escalation and dose expansion study of cisplatin micelle injection, to determine the maximum tolerated dose (MTD), and to initially explore the recommended dose of phase II clinical practice (RP2D). The second stage (stage II) is the cisplatin micelle injection cohort expansion study to evaluate the efficacy and safety of cisplatin micelle injection (HA132) in patients with advanced solid tumors.

Conditions

Advanced Malignant Solid Tumors

Outcome Measures

Primary Outcomes (6)

• Incidence of Dose-limiting Toxicities (DLTs) in Stage I

  Day 1 to 21 of Cycle 1 (each cycle of 21 days).

• Incidence of adverse events in Stage I

  Patients will be assessed for incidence and severity of adverse events(AEs) according to NCI-CTCAE criteria.

  From Baseline (Day 1) up to 28 days post last dose.

• Maximum tolerated dose (MTD) in Stage I

  Day 1 to 21 of Cycle 1 (each cycle of 21 days).

• Recommended phase 2 dose (RP2D) in Stage I

  The RP2D will be determined based on safety data including DLT, preliminary efficacy data,and PK data.

  Day 1 to 21 of Cycle 1 (each cycle of 21 days).

• Objective Response Rate (ORR) in stage Ⅱ

  Proportion of patients whose best overall response is CR or PR in studies assessed according to RECIST v1.1.

  Up to approximately 2 years.

• Confirmed objective response rate (ORR) in stage Ⅱ

  During the study period, the best overall response is the proportion of patients with confirmed CR or PR (ie, CR+PR) as assessed by Response Evaluation Criteria in Solid Tumors.(RECIST v1.1).

  Up to approximately 2 years.

Secondary Outcomes (8)

• PK Indicator: Area under plasma concentration vs time curve(AUC)、Peak plasma concentration(Cmax)、Terminal Half Life（T1/2）.

  Day 1 of Cycle 1 up to Day 1 of Last Cycle.

• ORR in Stage I

  Up to approximately 2 years.

• Confirmed ORR in Stage I

  Up to approximately 2 years.

• Progression-free survival (PFS)

  Up to approximately 2 years.

• Disease control rate (DCR)

  Up to approximately 2 years.

Study Arms (1)

Cisplatin micelle injection (HA132)

EXPERIMENTAL

Dose-escalation: Five dose levels have been selected for evaluation in the Phase Ⅰ of the study. Dose escalation decisions will be determined based on toxicities observed during the first cycle. Dose-expansion: Patients will be administered HA132 at one or two dose levels (e.g. MTD and the dose below MTD). Cohort-expansion: Patients will be administered HA132 at one or two dose levels (e.g. MTD and the dose below MTD).

Drug: Cisplatin micelle injection (HA132)

Interventions

Cisplatin micelle injection (HA132) DRUG

HA132 will be administered intravenously (IV), once per 3 weeks.
