DEER PARK, Ill., Oct. 04, 2023 (GLOBE NEWSWIRE) -- Eton Pharmaceuticals (“Eton” or “the Company”) (Nasdaq: ETON), an innovative pharmaceutical company focused on developing, acquiring, and commercializing products to address unmet needs in patients suffering from rare diseases, today announced it has entered into an agreement to acquire an abbreviated new drug application for Nitisinone Capsules via Oakrum Pharma, LLC’s Chapter 11 bankruptcy proceeding. The transaction has been approved by the bankruptcy court and is expected to be effective on October 12, 2023. The acquired product was approved by the U.S. Food and Drug Administration (FDA) in May of 2023 for the treatment of hereditary tyrosinemia type 1 (HT-1) in combination with dietary restriction of tyrosine and phenylalanine. It is estimated that less than 500 patients in the United States suffer from this ultra-rare condition.
“With a patient population of less than 500, Nitisinone is another opportunity for Eton to deliver on its mission of providing medicines to and supporting patients and families with rare conditions. Nitisinone is our fourth FDA-approved product, and further advances us toward our goal of having ten commercial rare disease products on the market by the end of 2025. Nitisinone also shares the same metabolic geneticist prescriber base as our Carglumic Acid and Betaine products, so this is an attractive opportunity to leverage our existing sales force and relationships with prescribers,” said Sean Brynjelsen, CEO of Eton Pharmaceuticals.
Eton expects to launch the product in the first quarter of 2024 and plans to offer its Eton Cares support program to all patients. The program is designed to help patients access treatment, providing prescription fulfillment services, insurance benefits investigation, educational support, and help in obtaining financial assistance for qualified patients, among other services. The current Nitisinone market is estimated to be over $50 million annually, and Eton believes the Company’s commercial advantages, including its Eton Cares program, existing relationships with prescribers, and experienced sales force should allow it to capture a meaningful percentage of the market.
USE and IMPORTANT SAFETY INFORMATION
What is Nitisinone?
Nitisinone is a prescription medicine used to treat adults and children with a hereditary disease called tyrosinemia type 1 (HT-1). Nitisinone should be taken along with a diet limiting tyrosine and phenylalanine.
What is the most important information I should know about Nitisinone?
Tell your doctor or nurse right away if you have any of these symptoms with Nitisinone:
Increased levels of plasma tyrosine, eye symptoms, developmental delay, and skin changes:
- Inadequate restriction of tyrosine and phenylalanine intake can result in raising plasma tyrosine levels.
- Plasma tyrosine levels above 500 micromol/L may lead to eye signs and symptoms like corneal ulcers, corneal cloudiness, inflammation of the cornea (keratitis), pink eye (conjunctivitis), eye pain, and sensitivity to light (photophobia), intellectual disability and developmental delay or painful thickening of the skin (hyperkeratotic plaques) on the soles and palms.
- Your healthcare provider should not adjust Nitisinone dosage in order to lower the levels of tyrosine in the blood.
Changes in blood profile
- You may develop a reduction in the number of white blood cells, which form part of the immune system (leukopenia) and abnormally low levels of platelets, which help the blood to clot (severe thrombocytopenia).
Do not take Nitisinone if:
- you are allergic to nitisinone or any other ingredients. Stop using Nitisinone and get medical help right away if you have any symptoms of a serious allergic reaction, including swelling of the face, lips, tongue, or throat; problems breathing or swallowing; severe rash or itching; fainting or feeling dizzy; or very rapid heartbeat.
Before taking Nitisinone, tell your doctor if you:
- are pregnant or plan to become pregnant. Nitisinone may harm your unborn baby. Tell your doctor if you become pregnant or suspect you are pregnant during treatment with Nitisinone.
- are breastfeeding or plan to breastfeed. It is not known if Nitisinone passes into your breast milk. Talk to your doctor about the best ways to feed your baby during treatment with Nitisinone.
- are aged 65 and older. Your doctor may need to adjust the dose of Nitisinone based on your requirements.
- are taking other medicines since Nitisinone can interfere with their effect. Tell your doctor about all the medicines you take, including prescription and over-the-counter medicines, vitamins, dietary and herbal supplements.
What are the possible side effects of Nitisinone?
The most common side effects of Nitisinone (≥1%) include high tyrosine levels, low platelets (thrombocytopenia) or white cells in the blood (leukopenia), and complaints related to the eyes, including pink eye (conjunctivitis), corneal cloudiness, inflammation of the cornea, eye pain and extreme sensitivity to light (photophobia), nosebleed (epistaxis), itching (pruritus), skin inflammation (exfoliative dermatitis), rash (maculopapular rash), dry skin and hair loss (alopecia).
