Anti-TNFα Therapy for Improving Pregnancy Rates in Endometriosis Patients With Failed ICSI

This prospective study targets infertile women with endometriosis (EM) who have experienced a previously failed Intracytoplasmic Sperm Injection (ICSI) trial. Using the P-I-C-O framework, the study evaluates whether the administration of an anti-TNF-α therapy (Intervention) 4-5 days before a frozen blastocyst transfer (FBT) improves reproductive outcomes compared to standard protocols (Comparison). The primary outcome is the clinical pregnancy rate, with secondary outcomes focusing on implantation, ongoing pregnancy, and neonatal health. The goal is to determine if mitigating pro-inflammatory cytokines like TNF-α can enhance endometrial receptivity in this specific high-risk population.

  • History of a previously failed ICSI trial.
  • Presence of more than one frozen embryo at the D-5 blastocyst stage qualified as good quality (Grade AA6).
  • Signed informed consent.

Exclusion criteria

  • Polycystic Ovary Syndrome (PCOS).
  • Inflammatory disorders other than endometriosis.
  • Currently maintaining immune-modulating therapies for any other cause.

Treatment and study plan

TNF-α Inhibitor

Drug

Administered 4-5 days before the frozen blastocyst transfer. A second session is provided two weeks later only for those with a positive chemical pregnancy diagnosis.

Frozen Blastocyst Transfer (FBT)

Procedure

Transfer of a D-5 blastocyst (Grade AA6) following a standardized endometrial preparation involving GnRH-agonist, estradiol valerate, and progesterone.

Primary outcomes

  1. The Success Rate of Treatment Regimens in Achieving Clinical Pregnancy

    Time frame: 4-6 weeks post-transfer.

    The proportion of patients who achieved a clinical pregnancy (confirmed by ultrasound visualization of a gestational sac with fetal heart activity) following frozen blastocyst transfer, reflecting the effectiveness of the administered anti- TNFα therapy.

Secondary outcomes

  1. Success Rate of Treatment in Achieving Healthy Neonatal Outcomes.

    Time frame: At the time of delivery (approximately 9 months post-transfer).

    A composite measure including live birth rate, birth weight, and absence of major neonatal complications/NICU admissions.
