Clinical Data

Trial Design:

Prospective, multi-center, unblinded clinical trials with historical control. Conducted under FDA Investigational Device Exemptions (IDEs). NCT03067272, NCT03433911, and NCT04273594.

Trial Results1:

(for subjects who met trial eligibility and were determined bilaterally blocked after confirmation test)

PRIMARY ENDPOINT
  • Pregnancy rate was 0% (n=51)

FemBloc demonstrated a significantly lower pregnancy rate than the historical control.


Historic Control:

Based on real-world effectiveness of surgical (laparoscopic) sterilization evaluated in a recent large study (N=23,965), which concluded:

  • "women considering surgical sterilization should be informed that after the procedure, women typically face at least a 6% chance of pregnancy in the next 5 years." 2

Note: CREST study (U.S. Collaborative Review of Sterilization) was conducted between 1978 and 1981 (N=10,685) and is considered outdated with 28% of the sterilization techniques examined no longer used.2

SAFETY
  • Adverse events 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)1

Participants are currently being enrolled in the FINALE pivotal clinical trial (NCT05977751) for U.S. approval.
