Summary

The study consists of five sequential periods:

* Screening (≤ 4 weeks)
* Correction phase
* Maintenance phase (first treatment cycle, Cycle 1)
* Observation phase (second treatment cycle, Cycle 2)
* Follow-up Eligible subjects are gynaecological-cancer patients who developed ≥ grade-2 cancer-therapy-induced thrombocytopenia (CTIT) after anti-tumour therapy, i.e. platelet count \< 75 × 10⁹/L.

* Stage 1\*\* - Prospective, multicentre, randomised clinical study (to inform the confirmatory stage 2) \*\*Cohort 1 (n = 30)\*\* Correction: hetrombopag 7.5 mg p.o. daily until PLT ≥ 100 × 10⁹/L. Within 24 h after completion of Cycle 1 anti-cancer therapy (end of chemotherapy if combined; otherwise end of investigational product on that day) restart hetrombopag 7.5 mg p.o. daily and continue until the last day of Cycle 1 (C1D21).

\*\*Cohort 2 (n = 30)\*\* Correction: hetrombopag 7.5 mg p.o. daily until PLT ≥ 100 × 10⁹/L. During Cycle 1, monitor PLT closely; if PLT falls \< 75 × 10⁹/L, initiate hetrombopag 7.5 mg p.o. daily and continue until C1D21.

\*\*Stage 2\*\* - Prospective, multicentre, randomised, controlled clinical study \*(preliminary design; sample size and details will be refined after stage-1 results)\* \*\*Experimental arm (n = 92)\*\* Correction: hetrombopag 7.5 mg p.o. daily until PLT ≥ 100 × 10⁹/L. Restart within 24 h after completion of Cycle 1 therapy and continue daily until C1D21.

\*\*Control arm (n = 92)\*\* Correction: hetrombopag 7.5 mg p.o. daily until PLT ≥ 100 × 10⁹/L. During Cycle 1, monitor PLT; if PLT \< 75 × 10⁹/L, initiate hetrombopag 7.5 mg p.o. daily until C1D21.

\*\*Correction-phase rules\*\* Discontinue hetrombopag once PLT ≥ 100 × 10⁹/L. If after ≥ 14 days of hetrombopag correction PLT remains \< 100 × 10⁹/L and the next treatment cycle has not started, the investigator may resume hetrombopag or institute alternative platelet-enhancing rescue therapy at their discretion.

Conditions

  • Chemotherapy Induced Thrombocytopenia

Interventions

DRUG

hetrombopag 7.5 mg orally once daily

Correction phase: start hetrombopag 7.5 mg orally once daily and continue until platelet count normalizes (PLT ≥ 100 × 10⁹/L). Within 24 h after completion of Cycle 1 anti-cancer therapy-defined as the end of chemotherapy infusion if on a combined regimen, or the end of study drug administration on that day for non-chemotherapy regimens-restart hetrombopag 7.5 mg orally once daily and maintain until the last day of Cycle 1 (C1D21).
