Gene Expression in Cumulus Cells to Predict Pregnancy

This study has been completed.
Information provided by (Responsible Party):
Gema Diagnostics Identifier:
First received: November 14, 2012
Last updated: July 11, 2014
Last verified: July 2014
The purpose of this study is to determine the performance of a genetic assay, GemART, in cumulus cells predictive of embryo viability, and pregnancy success in women undergoing in vitro fertilization (IVF). Performance is defined as success rate per embryo transferred, as measured by the implantation rate of embryos transferred.

Condition Intervention
Infertility Other: Morphology Other: GemART assay

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: The Predictive Value of a Gene Expression Signature in Cumulus Cells Indicative of Embryo Implantation.

Primary Outcome Measures:
  • Clinical pregnancy rate [ Time Frame: Recorded at post-transfer week 4-9 ]
    Clinical pregnancy, recorded as either positive or negative, will be determined using vaginal ultrasound during post-transfer week 4-9. Clinical Pregnancy rate for embryos selected using the GemART assay in conjunction with morphology will be compared with clinical pregnancy rate for embryos selected using morphology alone.

Enrollment: 133
Study Start Date: February 2013
Study Completion Date: March 2014
Primary Completion Date: March 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Morphology
Embryos selected for transfer will be based on morphology alone.
Other: Morphology
Embryos selected for transfer will be based upon morphology alone.
Experimental: GemART assay
Embryos selected for transfer will be based upon morphology and GemART assay.
Other: GemART assay
Embryos selected for transfer will be based upon morphology and GemART assay.
