- Tolmar’s 62-person sales force will co-promote ALKINDI SPRINKLE® to pediatric endocrinologists -

DEER PARK, Ill., Nov. 15, 2021 (GLOBE NEWSWIRE) -- Eton Pharmaceuticals, Inc (Nasdaq: ETON) today announced that it has entered into a multi-year agreement with Tolmar Pharmaceuticals, Inc. to co-promote ALKINDI SPRINKLE®. Eton will leverage Tolmar’s 62-person sales force and their existing relationships in the pediatric endocrinology specialty. Tolmar currently promotes FENSOLVI® (leuprolide acetate) for injectable suspension, indicated for pediatric patients 2 years of age and older with Central Precocious Puberty (CPP).

“It’s clear that physicians see the need for ALKINDI SPRINKLE’s accurate dosing when treating adrenal insufficiency, however, we have found that changing the decades old prescribing habits of pediatric endocrinologists is often requiring multiple face-to-face interactions. With this partnership, our reach will be increasing more than 10-fold and we will drastically increase the number of face-to-face interactions. We believe this will translate to significantly faster adoption of ALKINDI SPRINKLE and accelerate the time to reach peak conversion,” said Sean Brynjelsen, CEO of Eton Pharmaceuticals. “We are confident Tolmar is the right partner for ALKINDI SPRINKLE. Their FENSOLVI® launch results speak for themselves and highlight their team’s ability to drive treatment change in pediatric endocrinology,” added Brynjelsen.

“We are excited to co-promote ALKINDI SPRINKLE,” said Tolmar CEO Anil D’Souza. “This agreement will further enhance Tolmar’s commitment to the pediatric endocrinology space. It allows Tolmar to continue providing therapies with optimal delivery mechanisms that improve patient and caregiver experience.”

Tolmar’s pediatric endocrinology sales force currently promotes the specialty drug FENSOLVI® for CPP, a rare disease that impacts roughly one in 5,000-10,000 children in the United States. FENSOLVI® was launched in May 2020 and has already reached more than 1,500 patients.

Under terms of the agreement, Tolmar’s sales force will promote ALKINDI SPRINKLE® to their pediatric endocrinology targets alongside FENSOLVI®. Tolmar will receive a royalty on net sales growth above ALKINDI SPRINKLE®’s current baseline sales.   Eton’s sales force will continue to promote the product and Eton will maintain responsibility for all non-sales force related commercial activities.

The companies expect Tolmar’s sales force to start promoting ALKINDI SPRINKLE® in December. In tandem with the co-promotion launch, Eton plans to introduce an expanded digital marketing campaign targeted at raising awareness among patients and caregivers.

About ALKINDI SPRINKLE®
ALKINDI SPRINKLE® (hydrocortisone) oral granules is FDA-approved as replacement therapy for Adrenocortical Insufficiency (AI) in children under 17 years of age. ALKINDI SPRINKLE® is the first and only FDA-approved granular hydrocortisone formulation for the treatment of adrenocortical insufficiency specifically designed for use in children. The approval of ALKINDI SPRINKLE® was supported by six clinical studies, including the first and only interventional open-label Phase III study of oral hydrocortisone for Pediatric AI in neonates to children under eight years of age. Prior to the approval of ALKINDI SPRINKLE®, oral hydrocortisone was only FDA-approved in tablet formulations of 5mg and stronger. Many pediatric patients require significantly lower doses and the flexibility of precise titration. ALKINDI SPRINKLE® is available in 0.5mg, 1mg, 2mg, and 5mg strengths, allowing clinicians greater flexibility to individualize dosing based on each patient’s needs in accordance with the instructions for dosage and administration. Common adverse reactions for corticosteroids include fluid retention, alteration in glucose tolerance, elevation in blood pressure, behavioral and mood changes, increased appetite, and weight gain.

Important Safety Information for ALKINDI SPRINKLE® (hydrocortisone) Oral Granules

Adrenal Crisis: Undertreatment or sudden discontinuation of therapy may lead to symptoms of adrenal insufficiency, adrenal crisis, and death. Adrenal crisis may also be induced by stressor events, such as infections or surgery. Monitor patients closely when switching from other forms of hydrocortisone to ALKINDI SPRINKLE®. Increase the dose during periods of stress. Switch patients who are vomiting, severely ill, or unable to take oral medications to parenteral corticosteroid formulations.

Infections: Excessive doses may increase the risks of new infections or exacerbation of latent infections with any pathogen, including viral, bacterial, fungal, protozoan, or helminthic infections. Monitor patients for signs and symptoms of infections. Treat all infections seriously, and initiate stress dosing of steroids early.

Growth Retardation: Long-term use in excessive doses may cause growth retardation. Use the minimum dosage of ALKINDI SPRINKLE® to achieve desired clinical response and monitor the patient’s growth.

Cushing’s Syndrome Due to Use of Excessive Doses of Corticosteroids: Prolonged use with supraphysiologic doses may cause Cushing’s syndrome. Monitor patients for signs and symptoms of Cushing’s syndrome every 6 months; pediatric patients under one year of age may require more frequent monitoring.

Decrease in Bone Mineral Density: Corticosteroids decrease bone formation and increase bone resorption, which may lead to inhibition of bone growth and development of osteoporosis. Use the minimum dosage of ALKINDI SPRINKLE® to achieve desired clinical response.

Psychiatric Adverse Reactions: Use may be associated with severe psychiatric adverse reactions, such as euphoria, mania, psychosis with hallucinations and delirium, or depression. Symptoms typically emerge within a few days or weeks of starting the treatment. Most reactions resolve after either dose reduction or withdrawal, although specific treatment may be necessary. Monitor patients for behavioral and mood disturbances during treatment. Instruct caregivers and/or patients to seek medical advice if psychiatric symptoms develop.

Ophthalmic Adverse Reactions: Cataracts, glaucoma, and central serous chorioretinopathy have been reported with prolonged use of high doses. Monitor patients for blurred vision or other visual disturbances, and if they occur, refer them to an ophthalmologist.

Gastrointestinal Adverse Reactions: There is an increased risk of gastrointestinal perforation in patients with certain gastrointestinal disorders. Signs of gastrointestinal perforation, such as peritoneal irritation, may be masked in patients receiving corticosteroids. Corticosteroids should be used with caution if there is a probability of impending perforation, abscess, or other pyogenic infections; diverticulitis; fresh intestinal anastomoses; and active or latent peptic ulcer.

Concurrent administration of corticosteroids with nonsteroidal anti-inflammatory drugs (NSAIDs) may increase the risk of gastrointestinal adverse reactions. Monitor patients receiving corticosteroids and concomitant NSAIDs for gastrointestinal adverse reactions.

Adverse Reactions

Common adverse reactions for corticosteroids include fluid retention, alteration in glucose tolerance, elevation in blood pressure, behavioral and mood changes, increased appetite, and weight gain.

INDICATION

ALKINDI SPRINKLE® is a corticosteroid indicated for replacement therapy in pediatric patients with adrenocortical insufficiency.

Important Safety Information for FENSOLVI® (leuprolide acetate) for injectable suspension

FENSOLVI® (leuprolide acetate) for injectable suspension is a gonadotropin releasing hormone (GnRH) agonist used to treat patients 2 years of age and older with central precocious puberty (CPP). CPP may be diagnosed when signs of sexual maturity begin to develop in girls under the age of 8 or in boys under the age of 9.

FENSOLVI is contraindicated in individuals with hypersensitivity to any drug that is in the same class as FENSOLVI, in individuals who are allergic to any of the ingredients in FENSOLVI, or in individuals who are pregnant. FENSOLVI may cause fetal harm when administered to a pregnant patient.

During the first few weeks of treatment, increases in gonadotropins and sex steroids above baseline may result in an increase in signs and symptoms of puberty including vaginal bleeding in girls.

Psychiatric events have been reported in patients taking GnRH agonists. Events include emotional lability, such as crying, irritability, impatience, anger, and aggression. Patients should be monitored for development or worsening of psychiatric symptoms.

Convulsions have been observed in patients treated with GnRH agonists with or without a history of seizures, epilepsy, cerebrovascular disorders, central nervous system anomalies or tumors, and in patients on concomitant medications that have been associated with convulsions such as bupropion and SSRIs.

The most common adverse events seen with FENSOLVI were: injection site pain, nasopharyngitis, pyrexia, headache, cough, abdominal pain, injection site erythema, nausea, constipation, vomiting, upper respiratory tract infection, bronchospasm, productive cough and hot flush.
