Brief summary

The purpose of this study is to assessment the safety and tolerability of a new medication called FPT155. Who is it for? You may be eligible for this study if you are aged 18 or older and have a solid tumour. Study details All participants will be treated with a different amount of FPT155. This medication is administered through a needle in the arm once every 21 days for every 3 weeks .As part of this study, all participants will have a number blood tests, Hematology, Clinical chemistry, Coagulation, Urinalysis. It is hoped this research will demonstrate the safety and tolerability of this new medication and provide important does-related information for future studies.

Interventions

This is a Phase 1a/1b open-label, multicenter, dose escalation, dose exploration and dose expansion study to evaluate safety and tolerability of FPT155 in patients with advanced solid tumors. The Phase 1a dose escalation will identify a recommended dose for FPT155 for further clinical evaluation in Phase 1b. FPT155 will be administered every three weeks, on Day 1 of each 21-day cycle. Approximately 8 dose levels are anticipated in Phase 1a: • 0.07 mg FPT155 every three weeks • 0.21 mg FPT155

Approximately 8 dose levels are anticipated in Phase 1a: • 0.07 mg FPT155 every three weeks • 0.21 mg FPT155 every three weeks • 0.70 mg FPT155 every three weeks • 2.1 mg FPT155 every three weeks • 7.0 mg FPT155 every three weeks • 21.0 mg FPT155 every three weeks • 42.0 mg FPT155 every three weeks • 70.0 mg FPT155 every three weeks Route of Administration: Intravenous infusion Patients are assigned to a dose level based on the order of enrolment. duration of the intervention: Patients continue on treatment until they can no longer tolerate treatment or their disease has worsened (progressed) then patients will undergo end of treatment follow-up visits approximately 28 days and 100 days after the last dose of Study drug. Indication on how the dose for Phase 1b will be identified: Patient cohorts will be sequentially escalated in an accelerated titration design followed by a standard 3+3 dose escalation until the recommended dose is identified. Participants in Phase 1b will be treated with FPT155 at a recommended dose selected after assessment of data obtained in Phase 1a. Details of Phase 1b, including the mode of administration and the frequency/duration of treatment: Enrollment in Phase 1b dose expansion will begin when the recommended dose has been identified from Phase 1a. Up to 6 tumor-specific cohorts consisting of approximately 30 patients each will evaluate the safety, efficacy, PK, and PD of FPT155 at the recommended dose. Mode of administration: Intravenously every three weeks. Patients continue on treatment until they can no longer tolerate treatment or their disease has worsened (progressed).
