Spots Global Cancer Trial Database for HDM201 and Pazopanib in Patients With P53 Wild-type Advanced/Metastatic Soft Tissue Sarcomas

Study Description

Brief Summary: This trial is a two-step Phase I/II study comprising: Part 1: A dose escalation part with the aim to assess the safety of the proposed combination (N= up to 30 patients). In the dose escalation part, eligible patients will be treated with a fixed dose of pazopanib and escalating doses of HDM201. Part 2: An extension part to collect preliminary data about the clinical activity of the proposed combination according to the 6M-PFR.

Detailed Description: This trial is a two-step Phase I/II study comprising: Part 1: A dose escalation part with the aim to assess the safety of the proposed combination (N= up to 30 patients). The dose escalation will be conducted according to a sequential and adaptive Bayesian scheme using the method of Time-to-event Continual Reassessment Method (CRM) to guide dose escalation and estimate the Maximum Tolerated Dose. In the dose escalation part, eligible patients will be treated with a fixed dose of pazopanib (800 mg/d) and escalating doses of HDM201: 60 mg (starting dose); 80 mg; 100 mg; 120 mg. For a safety reason, a dose level of 40 mg is included in case that the first dose level is found to be toxic. In addition, decrease of pazopanib dosing to 600 mg/d could be appropriate following protocol amendment. To ensure adequate patient safety during the dose escalation part, there will be a 3-day delay between the first and subsequent patients enrolled in each DL cohort to maximize the safety of enrolled patients. No intra-patient dose escalation is allowed. Part 2: An extension part to collect preliminary data about the clinical activity of the proposed combination according to the 6 months Progression Free Rate (6M-PFR).
