Organon Completes Agreement to License MIUDELLA®, Sebela Pharmaceuticals’ Hormone-Free Intrauterine Device

This transaction strengthens Organon’s contraception portfolio and expands long-acting reversible options for women

Organon (NYSE:OGN), a global healthcare company with a mission to deliver impactful medicines and solutions for a healthier every day, today announced the completion of a global licensing agreement with Sebela Pharmaceuticals, granting Organon exclusive rights to MIUDELLA^®, a hormone-free, copper intrauterine device (IUD). Please see our prior announcement for a summary of the transaction terms.

Approved by the US Food and Drug Administration (FDA) on February 24, 2025, MIUDELLA is the first hormone-free copper IUD to be introduced in the US in over 40 years. Indicated for the prevention of pregnancy for up to three years in females of reproductive potential, MIUDELLA is 99% effective. It features a proprietary SLIMSERT^TM technology, which consists of a highly flexible frame and a fully preloaded inserter with a small, tapered insertion tube diameter of 3.7mm.¹

MIUDELLA is anticipated to be commercially available in late 2026. The MIUDELLA label includes a Risk Evaluation and Mitigation Strategy (REMS). A REMS is a strategy used by the FDA to manage known or potential risks associated with a product. To mitigate complications due to potential improper insertion, MIUDELLA will only be available in the US through the MIUDELLA REMS program. See additional safety information below.

"MIUDELLA represents an important hormone-free option in contraception, expanding choices for women seeking long‑acting reversible birth control," said Joe Morrissey, Chief Executive Officer of Organon. "By building on our long history in contraception and leveraging our deep expertise and capabilities, this agreement strengthens Organon’s ability to deliver contraceptive options that meet the needs of women."

"Developed by Sebela Women’s Health, MIUDELLA represents an effective option for pregnancy prevention," said Alan Cooke, Chief Executive Officer and President of Sebela Pharmaceuticals. "We are delighted to complete this global license agreement with Organon. Organon offers the scale, launch readiness and access capabilities needed to bring this valuable product efficiently into clinical practice and help ensure MIUDELLA reaches more women who are looking for hormone-free contraception options."

Truist Securities, Inc. acted as financial advisor to Sebela Pharmaceuticals.

About MIUDELLA

MIUDELLA was investigated in three clinical trials in the US in 1,904 women aged 17 to 45 years. The Phase 3 prospective, multicenter, single-arm, open-label study was conducted in 42 centers in the US with a primary endpoint of contraceptive efficacy through 3 years of use as assessed by the Pearl Index (defined as the number of pregnancies per 100 women over one year).¹ In the efficacy cohort of women aged 17 to 35 years from the Phase 3 study (n=1397), the first-year Pearl Index was 0.94 (95% CI, 0.43-1.78) and the cumulative 3-year Pearl Index was 1.05 (95% CI, 0.66-1.60)—in other words, 99% effective, with an overall placement success rate of 98.8%. The most common adverse reactions (≥5%) observed in clinical trials were heavy menstrual bleeding, dysmenorrhea, intermenstrual bleeding, pelvic discomfort, procedural pain, pelvic pain, post-procedural hemorrhage, and dyspareunia. In the first year, 8.5% of participants across all three studies discontinued treatment due to bleeding or pain adverse events, which decreased to 3.2% by year 3. Expulsion rates ranged from 1.9% in year 1 to 0.9% in year 3.

Indication

• MIUDELLA^® is a copper-containing intrauterine system (IUS) indicated for prevention of pregnancy in females of reproductive potential for up to 3 years.

Selected Safety Information

WARNING: RISK OF COMPLICATIONS DUE TO IMPROPER INSERTION

• Improper insertion of intrauterine systems, including MIUDELLA, increases the risk of complications.
• Proper training prior to first use of MIUDELLA can minimize the risk of improper insertion.
• MIUDELLA is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the MIUDELLA REMS program to ensure all healthcare providers are trained on the proper insertion of MIUDELLA prior to first use. Further information is available at miudellarems.com and 1-855-337-0772.

CONTRAINDICATIONS

• Use of MIUDELLA is contraindicated when 1 or more of the following conditions exist:
  • Pregnancy or suspicion of pregnancy; congenital or acquired abnormalities of the uterus, including leiomyomas, resulting in distortion of the uterine cavity; acute pelvic inflammatory disease (PID); postpartum endometritis or postabortal endometritis in the past 3 months; known or suspected uterine or cervical malignancy; for use as postcoital contraception (emergency contraception); uterine bleeding of unknown etiology; untreated acute cervicitis or vaginitis or other lower genital tract infection; conditions associated with increased susceptibility to pelvic infections; Wilson's disease; a previously placed IUS that has not been removed; hypersensitivity to any component of MIUDELLA including to polypropylene, copper, nitinol, an alloy of nickel and titanium, or any of the trace elements present in the copper component of MIUDELLA. Persons with allergic reactions to these components may suffer an allergic reaction to this intrauterine system. Prior to placement, patients should be counseled on the materials contained in the IUS, as well as potential for allergy/hypersensitivity to these materials.

WARNINGS AND PRECAUTIONS

• Risk of Complications Due to Improper Insertion: Improper insertion of IUSs, including MIUDELLA, increases the risk of perforation, infection, undiagnosed abnormal bleeding, pregnancy loss (if pregnancy occurs with IUS in situ), and expulsion. Proper training prior to first use of MIUDELLA can minimize the risk of improper insertion. MIUDELLA is available only through a restricted program under a REMS.
  
  
  
  
• MIUDELLA REMS: MIUDELLA is only available through a restricted program under a REMS called MIUDELLA REMS Program to ensure healthcare providers are trained prior to first use. Notable requirements include the following:
  • Healthcare providers must be certified with the program by enrolling and completing training on the proper insertion of MIUDELLA prior to first use.
  • Pharmacies and healthcare settings that dispense MIUDELLA must be certified by enrolling in the REMS and must only dispense MIUDELLA to certified healthcare providers.

Further information is available at www.miudellarems.com and 1-855-337-0772.

• Ectopic Pregnancy: Promptly evaluate females who become pregnant for ectopic pregnancy while using MIUDELLA. Ectopic pregnancy may require surgery and may result in loss of fertility.
  
  
  
  
• Intrauterine Pregnancy: Increased risk of spontaneous abortion, septic abortion, premature delivery, sepsis, septic shock, and death if pregnancy occurs. Remove MIUDELLA if pregnancy occurs with MIUDELLA in place and the thread ends are visible or can be retrieved from the cervical canal.
  
  
  
  
• Sepsis: Severe infection or sepsis, including Group A streptococcal sepsis (GAS), have been reported following insertion of other IUSs; strict aseptic technique is essential during insertion.
  
  
  
  
• Pelvic Infection: Promptly examine users with complaints of lower abdominal or pelvic pain, odorous discharge, unexplained bleeding, fever, genital lesions or sores after insertion of MIUDELLA. IUSs have been associated with an increased risk of PID, most likely due to organisms being introduced into the uterus during insertion. Remove MIUDELLA in cases of recurrent PID or endometritis, or if an acute pelvic infection is severe or does not respond to treatment.
  
  
  
  Subclinical PID: PID may be asymptomatic but still result in tubal damage and its sequelae.
  
  
  
  
• Perforation: Partial or total perforation of the uterine wall or cervix may occur during insertions, although the perforation may not be detected until sometime later. Perforation may also occur at any time during IUS use. Perforation that results in embedment or translocation may reduce contraceptive efficacy and result in pregnancy. Risk is increased if inserted in postpartum and lactating females and may be increased if inserted in females with fixed, retroverted uteri or noninvoluted uteri. If perforation is suspected or if known perforation occurs during placement, the IUS should be removed as soon as possible. Surgery may be required. Delayed detection or removal of MIUDELLA in cases of perforation may result in migration outside the uterine cavity, adhesions, peritonitis, intestinal penetration, intestinal obstruction, abscesses and/or damage to adjacent organs.
  
  
  
  
• Expulsion: Partial or complete expulsion of MIUDELLA has been reported, resulting in the loss of contraceptive protection. MIUDELLA should be placed no earlier than 4 weeks post-pregnancy to mitigate the risk of expulsion that may be increased when the uterus is not completely involuted at the time of insertion. Remove a partially expelled MIUDELLA and do not attempt to push a partially expelled MIUDELLA into the uterus.
  
  
  
  
• Wilson’s Disease: MIUDELLA may exacerbate Wilson’s disease, a rare genetic disease affecting copper excretion; therefore, the use of MIUDELLA is contraindicated in females with Wilson’s disease.
  
  
  
  
• Bleeding Pattern Alterations: Menstrual bleeding may be altered and result in heavier and longer bleeding with spotting. Females complaining of heavy vaginal bleeding should be evaluated and treated, and may need to discontinue MIUDELLA.
  
  
  
  
• Magnetic Resonance Imaging (MRI) Safety Information: Patients using MIUDELLA can be safely scanned with MRI only under certain conditions.
  
  
  
  
• Medical Diathermy: Medical equipment that contains high levels of Radiofrequency (RF) energy such as diathermy may cause health effects (by heating tissue) in females with a metal-containing IUS including MIUDELLA. Avoid using high medical RF transmitter devices in females with MIUDELLA.

ADVERSE REACTIONS

• Most common adverse reactions (≥5%) observed in clinical trials were heavy menstrual bleeding, dysmenorrhea, intermenstrual bleeding, pelvic discomfort, procedural pain, pelvic pain, post-procedural hemorrhage, and dyspareunia.
