ATLANTA, Feb. 25, 2025 (GLOBE NEWSWIRE) -- Femasys Inc., (Nasdaq: FEMY), a leading biomedical innovator addressing significant unmet needs in women's health worldwide, with a broad portfolio of disruptive, accessible, in-office therapeutic and diagnostic products, announces the peer-reviewed publication of positive data from its initial clinical trials of FemBloc® permanent birth control in the Journal of Gynecology & Reproductive Medicine (JGRM), a leading peer-reviewed journal covering gynecology and reproductive medicine.

“This peer-reviewed publication detailing positive prospective, multi-center clinical trial data for FemBloc brings Femasys closer to achieving our goal of providing a safer, more accessible in-office alternative to longstanding surgical sterilization for permanent contraception, without compromising effectiveness,” stated Kathy Lee-Sepsick, CEO of Femasys. “The investigators who participated in these clinical trials share a commitment to advancing women’s health by expanding contraceptive options with FemBloc, a much-needed advancement in permanent birth control.”

About the Data1

The publication entitled, “FemBloc Non-Surgical Permanent Contraception for Occlusion of the Fallopian Tubes” includes positive data from three initial clinical trials (Clinicaltrials.gov NCT03067272, NCT03433911, and NCT04273594). The pregnancy rate for FemBloc subjects, who met trial eligibility and were determined bilaterally occluded after a confirmation test three months post-FemBloc was 0% (95%UCB: 0.057; n=0/51). This is significantly lower than the performance goal of 6% based on the historical control, surgical sterilization (one-sided p-value=0.0426). Safety reports were consistent with those typically observed for intrauterine transcervical procedures, with no on-going safety concerns through five years. There were no reports of serious adverse events (n=0/229). The vast majority of subjects stated they would probably or definitely recommend FemBloc, and investigator satisfaction was similarly high.

About FemBloc

FemBloc® permanent birth control is a revolutionary first-of-its-kind non-surgical approach, that involves minimally-invasive delivery of a proprietary synthetic tissue adhesive to occlude the fallopian tubes, fully degrading and producing nonfunctional scar tissue, offering a safe and effective option to reduce the risk of unintended pregnancy. In contrast to historic surgical sterilization, the FemBloc approach offers a non-surgical, more accessible in-office alternative with fewer risks, contraindications, and substantially lower cost. Participants are being enrolled in the FINALE pivotal clinical trial (NCT05977751) for U.S. approval. Peer-reviewed publication of positive data from its initial clinical trials of FemBloc have demonstrated compelling effectiveness and five-year safety with high satisfaction from both patients and practitioners.1 Learn more at www.FemBloc.com.
