A Study to Evaluate the Safety, Tolerability, Preliminary Efficacy of KRC-01

Cervical Cancer Clinical Trial

Official title: A Phase 1/2 Study to Evaluate the Safety, Tolerability, Preliminary Efficacy of KRC-01 Intratumoral Injection Combined With Radiotherapy in Patients With Locally Advanced Cervical Cancer

Status Not yet recruiting

Clinical Trial Summary

This is a seamless Phase 1/2 study consisting of two components. Phase 1 component is a dose-escalation, single arm, open label study in 10 patients to evaluate the safety and tolerability of KRC 01. Phase 2 component is a randomized, open label, controlled, multi-center study in 60 patients to evaluate the preliminary antitumor effect of KRC-01 in combination with CRT.

Clinical Trial Description

This is a seamless Phase 1/2 study consisting of two components. Phase 1 component is a dose-escalation, single arm, open label study in 10 patients to evaluate the safety and tolerability of KRC 01. Phase 2 component is a randomized, open label, controlled, multi-center study in 60 patients to evaluate the preliminary antitumor effect of KRC-01 in combination with CRT.

Phase 1 component (n=10) Phase 1 component is a dose-escalation single arm, open label study. All eligible subjects will receive external beam radiotherapy (EBRT) with cisplatin (40 mg/m2) intravenously (IV) once weekly for 5 weeks (sixth dose optional) followed by image-guided brachytherapy (BT).

KRC-01 will be dosed intratumorally within 2 hours prior to EBRT starting from second week of EBRT.

There are two cohorts (n=5 per cohort) Cohort 1: Once-a-week between Monday to Thursday (not necessarily the same day every week) Cohort 2: Twice-a-week with a 1- or 2- day interval (either Mon+Wed, Mon+Thu, or Tue+Thu)

After 5 subjects of Cohort 1 have completed CRT+BT, the safety review committee (SRC) will evaluate the safety and tolerability of KRC-01 once-a-week dosing and determine Go/ No Go decision to Cohort 2 (twice-a-week dosing).

After all 10 subjects have completed CRT+BT, the SRC will evaluate the safety and tolerability of KRC 01 and determine Go/ No Go decision to Phase 2 component with optimal dosing regimen.

Phase 2 component (n=60) Phase 2 component is a randomized, open label study. All eligible subjects will be randomized to Standard of care (SOC) group or SOC with KRC-01 group.

All subjects will receive EBRT with cisplatin (40 mg/m2) IV once-a-week for 5 weeks (sixth dose optional) followed by image-guided BT. Only for KRC-01 group, KRC-01 will be dosed intratumorally at the optimal dosing schedule selected in Phase 1 component within 2 hours prior to EBRT starting from second week of EBRT. ;
