Aligns with Eton’s Mission to Develop and Distribute Medicines that Have a Life Changing Impact for Patients with Ultra-rare Conditions
Acquisition to Bolster Eton’s Commercial Pediatric Endocrinology Portfolio
DEER PARK, Ill., Oct. 03, 2024 (GLOBE NEWSWIRE) — Eton Pharmaceuticals, Inc (“Eton” or “the Company”) (Nasdaq: ETON), an innovative pharmaceutical company focused on developing and commercializing treatments for rare diseases, today announced that it has entered into an asset purchase agreement to acquire Increlex® (mecasermin injection) from Ipsen S.A. (“Ipsen”). The acquisition is expected to close near year-end 2024.
“Eton’s mission is to develop and distribute medicines that make a life changing impact for patients with the rarest of conditions. Increlex, a critical medication for patients with the ultra-rare condition of severe IGF-1 deficiency, aligns perfectly with our mission and our significant expertise in serving extremely rare patient populations,” said Sean Brynjelsen, CEO of Eton Pharmaceuticals. “Leveraging our strong presence in the pediatric endocrinology community, we aim to raise awareness of this underdiagnosed and undertreated condition. We look forward to collaborating with Ipsen to ensure continuity of care and long-term supply for patients globally.”
Increlex is a biologic product used to treat children and adolescents from 2- to 18-years-old who suffer from severe primary insulin-like growth factor 1 deficiency (SPIGFD) because their bodies do not make enough insulin-like growth factor 1 (IGF-1). The medicine is approved in 40 territories, including the United States (U.S.) and the European Union (EU). It is estimated that approximately 200 patients in the United States and 900-1,000 patients in Europe live with SPIGFD. Increlex is the only treatment approved by the U.S. Food and Drug Administration (FDA) or European Medicines Agency (EMA) for SPIGFD.
Post closing, Eton will immediately commercialize the product in the U.S. without disruption to patient supply. Outside the U.S., Ipsen will continue distributing the product during a six-month transition period to ensure no disruption to patient supply, after which the commercialization will be continued by Eton.
The transaction will be financed by Eton’s cash on hand and an expansion of the Company’s existing credit facility with SWK Holdings. Ipsen reported global sales for Increlex of €17.3 million in 2023.
Important Safety Information
Contraindications
- Hypersensitivity to mecasermin (rhIGF-1), any of the inactive ingredients in INCRELEX®, or who have experienced a severe hypersensitivity to INCRELEX®. Allergic reactions have been reported, including anaphylaxis requiring hospitalization.
- Intravenous Administration.
- Closed Epiphyses.
- Benign and malignant Neoplasia in pediatric patients with active or suspected neoplasia or medical history with an increased risk of benign or malignant neoplasia.
Warnings and Precautions
- Hypoglycemia: INCRELEX® should be administered 20 minutes before or after a meal or snack and should not be administered when the meal or snack is omitted. Glucose monitoring and INCRELEX® dose titration are recommended until a well-tolerated dose is established and as medically indicated.
- Intracranial Hypertension: Funduscopic examination is recommended at the initiation of and periodically during the course of therapy.
- Lymphoid Tissue Hypertrophy: Patients should have periodic examinations to rule out potential complications.
- Slipped Capital Femoral Epiphysis: Carefully evaluate any pediatric patient with the onset of a limp or hip/knee pain during INCRELEX® therapy.
- Progression of Scoliosis: Patients with a history of scoliosis, treated with INCRELEX®, should be monitored.
- Cardiomegaly: An echocardiogram is recommended before initiation and at termination of mecasermin treatment in all patients
- Benign and malignant neoplasms: There have been postmarketing reports of malignant neoplasia in pediatric patients who received treatment with INCRELEX®. The tumors were observed more frequently in patients who received INCRELEX® at higher than recommended doses or at doses that produced serum IGF-1 levels above the normal reference ranges for age and sex. Monitor all patients receiving INCRELEX® carefully for development of neoplasms. If malignant neoplasia develops, discontinue INCRELEX® treatment.
- Risk of Serious Adverse Reactions in Infants due to Benzyl Alcohol Preserved Solution: Serious and fatal adverse reactions including “gasping syndrome” can occur in neonates and infants treated with benzyl alcohol-preserved drugs. Use of INCRELEX® in infants is not recommended as well as in children below 3 years old.
Adverse Reactions
Common adverse reactions include hypoglycemia, local and systemic hypersensitivity, and tonsillar hypertrophy.
U.S. Indication
INCRELEX® (mecasermin) is indicated for the treatment of growth failure in pediatric patients aged 2 years and older with severe primary IGF-1 deficiency* (IGFD), or with hormone (GH) gene deletion who have developed neutralizing antibodies to GH.
Limitations of use: INCRELEX® is not a substitute to GH for approved GH indications. INCRELEX® is not indicated for use in patients with secondary forms of IGFD, such as GH deficiency, malnutrition, hypothyroidism, or chronic treatment with pharmacologic doses of anti-inflammatory steroids.
*Severe primary IGF-1 deficiency (IGFD) is defined by height standard deviation score ≤ -3.0 and basal IGF-1 standard deviation score ≤ -3.0 and normal or elevated GH.

You are encouraged to report negative effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch, or call 1-800-FDA-1088.
EU Indication
In the European Union, INCRELEX is indicated for the long-term treatment of growth failure in children and adolescents from 2 to 18 years with confirmed severe primary insulin-like growth factor 1 deficiency (Primary IGFD). Severe Primary IGFD is defined by: height standard deviation score <–3.0 and basal IGF-1 levels below the 2.5th percentile for age and gender and GH sufficiency. Exclusion of secondary forms of IGF 1 deficiency, such as malnutrition, hypopituitarism, hypothyroidism, or chronic treatment with pharmacologic doses of anti-inflammatory steroids.
Severe Primary IGFD includes patients with mutations in the GH receptor (GHR), post-GHR signaling pathway, and IGF 1 gene defects; they are not GH deficient, and therefore, they cannot be expected to respond adequately to exogenous GH treatment. In some cases, when deemed necessary, the physician may decide to assist in the diagnosis by performing an IGF-I generation test.
