A Multi-Center Study To Evaluate Multiple Doses of NT100 Following IVF In Women With Repeated IVF Failures (Thrive-IVF)

Phase 2
Completed
Conditions
Repeated IVF Failure
Interventions
Drug: Placebo
Registration Number
NCT01864356
Lead Sponsor
Nora Therapeutics, Inc.
Brief Summary

The purpose of this study is to evaluate the efficacy, safety and tolerability of multiple doses of subcutaneous NT100 vs placebo following in vitro fertilization (IVF) in women with a history of repeated IVF failures.

Detailed Description

NT-03 will be a randomized, double blind, multi-center, placebo controlled study of multiple doses of subcutaneous NT100 following IVF in women with a history of repeated IVF failures. Approximately 150 subjects will be randomized in a 1:1:1 ratio to receive subcutaneous NT100 low dose, NT100 high dose, or placebo, qd for up to 4 weeks.

Screening will include a standard IVF stimulation protocol, followed by fertilization and culture of embryos. If the subject remains eligible, she will be randomized to receive study drug. All subjects will be followed for 4 weeks after the last dose of study drug. At Week 10 of gestation, subjects who are pregnant will roll over into a follow-up study (NT-04) to assess subsequent pregnancy, delivery, and neonatal outcomes.
