Clinical Trial Summary

Title of Study:

An Open-Label, Single-Arm, Two-Stage, Multicenter, Phase II Study to Evaluate the Efficacy and Safety of TLC388 as Second-line Treatment in Subjects with Poorly Differentiated Neuroendocrine Carcinomas

Investigational product:

Lipotecan®*

*Lipotecan® is the trade name of TLC388 HCl, a Topoisomerase I inhibitor)

Phase of development:

Phase II

Number of subjects:

Plan to enroll 44 subjects

Objectives:

Primary objectives:

To determine the objective response rate

Secondary objectives:

To evaluate Disease control rate, Progression free survival, Overall survival, Safety profile and Biomarkers

Description:

This is a phase II, open-label, single-arm, two-stage, multicenter study to evaluate the efficacy and safety of Lipotecan® monotherapy in subjects with poorly differentiated neuroendocrine carcinomas. Only those subjects who have failed to first line chemotherapy (Etoposide plus platinum) due to treatment intolerance or radiographic progressive disease (PD), as per RECIST v1.1, are eligible to participate in the study. The scheduled assessments should be performed as identified on a calendar schedule, and should not be affected by delays in therapy, drug holidays or any other events that might be lead to imbalance in a treatment arm in the timing of disease assessment. Efficacy results are based on radiographic assessments reviewed by the investigator.

Eligible subjects will receive 40 mg/m2 of Lipotecan®, given as a 30 (+3) minute intravenous infusion, on Days 1, 8 and 15 of a 28-day cycle until PD, unacceptable toxicity or consent withdrawal occurs.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	the objective response rate	Analysis for the objective response rate will be conducted on both the per protocol(PP) and evaluable data sets.	5 years
Secondary	Disease control rate	The Disease control rate (DCR) is the percentage of subjects who have a best-response rating of CR or PR or SD (DCR= CR+PR+SD) (according to RECIST v1.1) when assessed after every 8 weeks of study drug (up to 6 cycles) and maintained for at least 28 days.	5 years
Secondary	Progression free survival	Progression-free survival will be calculated as the duration between the first date of randomization and the date of disease recurrence or progression according to RECIST v1.1 (failed), taking the status of tumor at the treatment has been completed as the reference, or death (failed), or the date of withdrawal (last contact date, censored), or the scheduled data analysis date (censored).	5 years
Secondary	Overall survival	Overall survival will be calculated from the date of randomization to either the date of death from all causes, or to the date of withdrawal (last contact date, censored), or to the scheduled data analysis date (censored).	5 years
Secondary	Number of Participants with Adverse Events as a Measure of Safety and Tolerability	Physical examinations, lab abnormality and other toxicities graded by the NCI Common Toxicity Criteria will be examined to evaluate safety profiles of the study treatments. Particular attention will be paid to Grade 3 or 4 toxicities.	5 years
