Individual dosing of Follitropin Delta for ovarian stimulation in infertility treatment

The Performance of an Individual Dosing Regimen of Follitropin Delta for Controlled Ovarian Stimulation for IVF in a Real-word Setting: a Non-interventional Observational Study

Observational University of Luebeck · NCT05173597

This study is testing if adjusting the dose of a hormone called Follitropin Delta based on a woman's weight and hormone levels can help improve ovarian stimulation for women undergoing IVF or ICSI.

What this trial studies

This observational study focuses on the individual dosing of Follitropin Delta, a follicle-stimulating hormone (FSH) preparation, for ovarian stimulation in women undergoing in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). The dosing is tailored based on the patient's body weight and serum anti-Müllerian hormone (AMH) levels to optimize ovarian response and minimize risks. The study includes a diverse patient population, including those with varying body weights and AMH levels, to reflect real-world scenarios. The goal is to improve the effectiveness of ovarian stimulation while reducing the likelihood of complications such as ovarian hyperstimulation syndrome.

Who should consider this trial

Good fit: Ideal candidates are women aged 18 to 44 years who are planning to undergo ovarian stimulation with Follitropin Delta as part of their fertility treatment.

Not a fit: Patients with very low serum AMH levels (≤0.3 ng/ml) or those who have not had their AMH levels tested within the last 12 months may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance the success rates of IVF and ICSI treatments for patients struggling with infertility.

How similar studies have performed: While individual dosing approaches have been explored, this specific observational study aims to gather real-world evidence, making it a novel contribution to the field.
