Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing

Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This early-stage trial tests whether anti-estrogen drugs (fulvestrant or anastrozole) can shrink inguinal hernias in men aged 50 and older. Thirty men with a symptomatic hernia will receive one of the drugs for 6 months. The main goal is to check safety and see if the hernia gets smaller on ultrasound.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Fulvestrant and anastrozole (anti-estrogen drugs)
What this could lead to
If successful, this could point toward a non-surgical way to treat inguinal hernias in older men.
What could go wrong
This is a very early Phase 1 trial with only 30 men, so it may not show any benefit. The drugs can cause side effects like bone loss or hormone changes.

Inclusion Criteria: * Male sex * Age ≥ 50 years at time of enrollment * Symptomatic unilateral inguinal hernia confirmed on physical examination * Hernia visible / confirmed on groin ultrasound * Non-recurrent inguinal hernia (primary hernia only) * Willing and able to provide written informed consent * Able and willing to comply with all protocol-required visits, laboratory assessments, imaging, and follow-up * Willing to use contraception and avoid fathering a child during study participation and for 12 months after last dose * Willing to be counseled regarding vitamin D and calcium supplementation Bone safety mitigation measure per PIND response. Exclusion Criteria: Hernia Characteristics * Scrotal hernia (any) * Bilateral inguinal hernia * Recurrent inguinal hernia (prior repair at same site) Renal \& Hepatic * Clinically significant renal dysfunction judged by investigator to increase study risk * Clinically significant hepatic dysfunction at baseline Hematologic ■ Clinically significant baseline hematologic abnormality (including elevated hematocrit or polycythemia) Urologic / Prostate * Symptomatic benign prostatic hyperplasia (BPH) requiring active medical or procedural treatment * Clinically significant untreated prostate disease Skeletal / Bone * Baseline osteoporosis (T-score ≤ -2.5 on DEXA at any site) * Recent fragility fracture (within prior 12 months or as judged by investigator) * Other clinically significant skeletal vulnerability judged to increase risk from estrogen suppression Immunosuppression ■ Active immunosuppression (e.g., systemic corticosteroids, biologic agents, post-transplant regimens) Psychiatric ■ Unstable or uncontrolled psychiatric illness that, in the investigator's judgment, would interfere with safe study participation Reproductive / Fertility ■ Actively pursuing fertility or planning conception during study participation Prior / Concomitant Therapy * Current use of androgen replacement therapy, exogenous estrogen, or other endocrine-active agents that would confound study interpretation * Prior or current use of aromatase inhibitor or selective estrogen receptor modulator / degrader within 6 months of enrollment General ■ Any other clinically significant medical condition, laboratory abnormality, or circumstance that, in the investigator's judgment, would place the participant at unacceptable risk or compromise study integrity
