Brief Summary:

CCI-001 is a novel colchicine derivative that is being developed by PharmaMatrix Holdings Ltd. (PharmaMatrix). The drug binds to tubulin, a component of the microtubule polymers which are required for a wide range of cellular processes, perhaps most importantly, cell division and mitosis. CCI-001 has been shown to bind more strongly to β-III tubulin, a tubulin subtype which is overexpressed in many cancers.

This trial is being undertaken as a first-in-human, Phase I trial in patients with recurrent and/or metastatic solid tumours. Primary Objectives are to examine the compound's safety profile, to determine the recommended dose, and to determine pharmacokinetic parameters and metabolism.

Secondary Objectives are to evaluate the clinical response rate and survival. Expansion cohorts in in tumour types known to be sensitive to other approved agents with similar mechanism of action will be treated at the recommended dose: transitional cell bladder cancer, pancreaticobiliary adenocarcinomas, gynecologic cancers (ovarian, cervical, endometrial), and lung adenocarcinoma.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 70 participants
Allocation: N/A
Intervention Model: Sequential Assignment
Intervention Model Description:

This is an open-label, single-arm, single-center, Phase I dose-escalation study of CCI-001 in patients with recurrent and/or metastatic solid tumours.

Patients will be treated in cohorts of 3, with the starting cohort having an assigned dose of CCI-001 of 1.2 mg/m2. If safety criteria are met, subsequent cohorts will be administered escalating doses of CCI-001, using the modified accelerated dose-escalation method.

Any cohort in which a patient experiences DLT in Cycle 1 will be expanded to 6 patients. Dose escalation will continue if only 1 of 6 patients in a cohort experiences DLT. If 2 patients within a cohort experience DLT, the maximum tolerated dose will have been reached/exceeded.

The cohort at the dose below this cohort will be expanded to 6 patients to ensure tolerability. If none of the 3 additional patients at this lower dose experiences DLT, that dose will be declared as the recommended dose for the dose expansion phase.

Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 1 Open-Labelled, Single-Arm, Dose-Escalation, Clinical and Pharmacology Study of CCI-001 in Patients With Recurrent and/or Metastatic Solid Tumours
Estimated Study Start Date : May 2021
Estimated Primary Completion Date : May 2023
Estimated Study Completion Date : May 2023

Arm Intervention/treatment
Experimental: Dose Escalation and Expansion

Dose escalation phase: CCI-001 will be administered at the starting dose to a cohort of patients with recurrent and/or metastatic solid tumours. The dose will be escalated sequentially in subsequent cohorts to determine the maximum tolerated dose, or recommended dose for the dose expansion cohort.

Dose expansion phase: patients with the following tumour types will be permitted to enroll: transitional cell bladder cancer, pancreaticobiliary adenocarcinomas, gynecologic cancers (ovarian, cervical, endometrial), and lung adenocarcinoma. These patients will be treated at the dose determined during the dose escalation phase.

Drug: CCI-001

Dose Escalation Phase: CCI-001 will be administered by intravenous infusion starting at 1.2mg per square metre of body surface area in the first cohort. The dose will be escalated sequentially in subsequent cohorts. The degree of dose escalation between subsequent cohorts will depend on tolerability, as judged by NCI-CTCAE grading. Once the maximum tolerated dose is determined this phase will be complete.

Dose Expansion Phase: cohorts of patients with the following tumour types will be enrolled: transitional cell bladder cancer, pancreaticobiliary adenocarcinomas, gynecologic cancers (ovarian, cervical, endometrial), and lung adenocarcinoma. These patients will be treated at the dose determined in the dose escalation phase.





Primary Outcome Measures :
  1. To determine the dose-limiting toxicity (DLT) of intravenously infused CCI-001 in patients with recurrent and/or metastatic solid tumours. [ Time Frame: Cycle 1 (28 days) ]
    DLT in this study will be determined against a pre-defined set of criteria based on the NCI-CTCAE v. 5.0 grading system.

  2. To determine, during the dose escalation phase, the recommended dose of intravenously infused CCI-001 for the dose expansion phase of the trial. [ Time Frame: Cycle 1 (28 days) ]
    The recommended dose will be the dose level below that for the cohort in which maximum tolerated dose (MTD) was reached/exceeded. MTD will have been reached when 2 or more patients in a cohort experience DLT.

  3. To determine the time to maximum plasma level (Tmax) of CCI-001 administered intravenously. [ Time Frame: Measured on Cycle 1 Days 1 and 15, Cycle 2 Day 1 (Each cycle is 28 days) ]
    Tmax is the time at which the maximum plasma CCI-001 concentration is achieved.

  4. To determine the maximum plasma concentration (Cmax) of CCI-001 administered intravenously. [ Time Frame: Measured on Cycle 1 Days 1 and 15, Cycle 2 Day 1 (Each cycle is 28 days) ]
    Cmax is the maximum plasma CCI-001 concentration that is achieved post administration.

  5. To determine the area under the curve (AUC) of CCI-001 administered intravenously. [ Time Frame: Measured on Cycle 1 Days 1 and 15, Cycle 2 Day 1 (Each cycle is 28 days) ]
    AUC is the measure of total CCI-001 exposure after administration.

  6. To determine the terminal half life (t1/2) of CCI-001 administered intravenously. [ Time Frame: Measured on Cycle 1 Days 1 and 15, Cycle 2 Day 1 (Each cycle is 28 days) ]
    t1/2 is the measure of the time it takes CCI-001 plasma concentration to decrease by 50%, after administration.


Secondary Outcome Measures :
  1. To evaluate the clinical response rate in patients treated with CCI-001 with recurrent and/or metastatic solid tumours, with particular attention to those in expansion cohorts [ Time Frame: Patients will have a baseline scan prior to dosing, and re-evaluated with imaging every 8 weeks. To continue from baseline scan to first documented date of disease progression, or date of death from any cause, to a maximum of 36 months. ]
    All patients with measurable disease will be assessed by standard criteria. Response Evaluation Criteria in Solid Tumours (RECIST) 1.1 criteria will be utilized to determine response based on CT and/or MRI scans.

  2. To evaluate survival in patients treated with CCI-001 with recurrent and/or metastatic solid tumours, with particular attention to those in expansion cohorts [ Time Frame: Start of treatment period (Cycle 1, Day1) to 30 days past the last treatment. Each Cycle is 28 days. ]
    Descriptive statistics will be utilized to evaluate patient survival.
