Assessment of Safety, Tolerability and PK Profile of MSP008-22 in Patients With Advanced Solid Tumours

Study Overview
=================
Brief Summary
-----------------
This is the 'first-in-human' clinical trial of the Investigational Medicinal Product (IMP), Tablet formulation for Oral dosing of MSP008-22, a molecule (new chemical entity) with anticancer properties.

Detailed Description
-----------------
This Single Ascending Dose (SAD) clinical trial is designed to evaluate the safety and tolerability of single oral ascending doses of the IMP in patients with Stage IV of advanced solid tumours including but not limited to Breast cancer including Triple-negative breast cancer, Ovarian cancer, Prostate cancer, Head and Neck squamous cell cancer). The trial will also assess the pharmacokinetic (PK) profile of MSP008-22 in humans. The safety, tolerability and PK data from this trial will determine the safety of MSP008-22 for dosing in humans in further clinical trials. As MSP008-22 has shown efficacy in in vitro studies against various cancer cell lines and in prostate and breast cancer cell lines in xenograft studies, the first in human trial of MSP008-22 is planned in patients of 'Stage-IV of Advanced Solid Tumours (Breast cancer including Triple-negative breast cancer, Ovarian cancer, Prostate cancer, Head and Neck squamous cell cancer and other advanced solid tumors).

Design Details

Primary Purpose: Basic Science
Intervention Model: Single Group Assignment
Interventional Model Description: At least 3 patients will be enrolled at only one dose level and dosed with one only dose of MSP008-22. Each dosed patient will be evaluated for 72.00 hours post-dose for primary and secondary endpoints (i) If there are no AE or abnormal laboratory results experienced by these three patients, the trial will move to the next dose level (next cohort of 3 different patients), (ii) If in a single Cohort, any one patient experiences any Dose Limiting Toxicity, additional 3 patients will be dosed at the same dose level, (iii) If in a single Cohort, more than 33% of the patients experience Dose Limiting Toxicity, the Cohort will be stopped, and further dose escalation will not happen in the study.
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: MSP008-22 treatment arm<br>Oral Escalating doses of MSP008-22- total five doses, each in form of a single dose oral formulation/tablet. Each trial participant will receive only one single oral dose of 05 identified dose levels of MSP008-22. Intra-patient dose escalation will not be carried out | Drug: MSP008-22<br>* It is single group assignment interventional model in this clinical trial, consisting of 5 cohorts of 3 patients in each, to be enrolled such that there exists an overall gender balance for the entire trial and to also ensure including minimum five (5) patients of TNBC and minimum five (5) male patients. The trial will be initiated with dosing of a cohort of 03 patient with the Safe starting dose for MSP008-22. Dosing of the patients for the next higher dose cohort will initiate only after: (i) All 03 patients have been recruited in the lower dose Cohort and if a repeat Cohort at this dose level is recommended, another 03 patients have been recruited at same dose level (ii) all dosed patients have completed the allocated study cohort duration, (iii) safety and pharmacokinetic results have been reviewed by the Independent Dose Escalation Committee (DEC) and approved for dose escalation to next cohort.<br>|
