U.S. and EU Patent Office Decisions Invalidate Amgen Subsidiary Immunex's Patents Claiming Antibodies to the IL-4 Receptor
TARRYTOWN, N.Y., Feb. 15, 2019 /PRNewswire/ --
Today the European Patent Office invalidated Immunex's European patent claiming antibodies that target human IL-4 receptors (IL-4R)
Decision follows yesterday's ruling by the U.S. Patent & Trademark Office invalidating a similar Immunex patent claiming antibodies that target human IL-4R
Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced two important legal developments invalidating Immunex patents with functional claims to antibodies that target human interleukin-4 receptors (IL-4R). Earlier today, the Opposition Division of the European Patent Office (EPO) revoked Immunex's European Patent No. 2,990,420 in its entirety because the claims were invalid for insufficiency of disclosure. This follows a decision yesterday by the Patent Trial and Appeal Board (PTAB) of the U.S. Patent & Trademark Office (USPTO) to invalidate all 17 claims of Immunex's U.S. Patent No. 8,679,487 as obvious. These decisions are subject to appeal by Immunex.
The patents in question are owned by Immunex Corporation, which is wholly-owned by Amgen.
"We applaud decisions by the U.S. and European patent offices this week, which invalidate Immunex's functional patent claims to antibodies that target human IL-4 receptors," said Joseph LaRosa, Executive Vice President, General Counsel and Secretary, Regeneron. "It is our position that Immunex's functional claims unfairly attempt to claim ownership far beyond the molecules developed, and stifle innovation within the broader scientific community."
Dupixent® (dupilumab), jointly developed by Regeneron and Sanofi, has been used to treat nearly 50,000 patients in the U.S. alone since it was first approved in 2017. Dupixent is a targeted biologic therapy that binds to IL-4R and inhibits signaling of IL-4 and IL-13, two key proteins that play a central role in Type 2 inflammation that underlies a number of allergic diseases, including atopic dermatitis and asthma.
Today's EPO decision follows a ruling in November 2017 (published in January 2018), invalidating a similar Immunex European patent also claiming antibodies that target human IL-4R.
Dupixent comes in two doses (200 mg and 300 mg), each as a pre-filled syringe. Dupixent is intended for injection under the skin (subcutaneous injection) and is given every other week at different injection sites after an initial loading dose. It can be given in a clinic or, for convenience, at home by self-administration after training by a healthcare professional.
Dupixent is approved in the U.S. as a treatment for adults with moderate-to-severe atopic dermatitis whose disease is not adequately controlled with topical prescription therapies or when those therapies are not advisable; and as add-on maintenance treatment for patients 12 years and older with moderate-to-severe asthma with an eosinophilic phenotype or with oral corticosteroid-dependent asthma.
In the EU, Dupixent is approved for use in adults with moderate-to-severe atopic dermatitis who are candidates for systemic therapy.
Dupilumab Development Program
Regeneron, in collaboration with Sanofi, is also studying dupilumab in a broad range of clinical development programs for diseases driven by allergic and other Type 2 inflammation, including chronic rhinosinusitis with nasal polyps (Phase 3 completed), adolescent (12 to 17 years of age) atopic dermatitis (Phase 3 completed), pediatric (6 to 11 years of age) atopic dermatitis (Phase 3), pediatric (6 months to 5 years of age) atopic dermatitis (Phase 2/3), pediatric (6 to 11 years of age) asthma (Phase 3), eosinophilic esophagitis (Phase 3) and food and environment allergies (Phase 2). A future trial is planned for chronic obstructive pulmonary disease. Dupilumab is also being studied in combination with REGN3500, which targets IL-33. These potential uses are investigational and the safety and efficacy have not been evaluated by any regulatory authority. Dupilumab and REGN3500 were discovered using Regeneron's proprietary VelocImmune® technology that yields optimized fully human antibodies, and are being jointly developed by Regeneron and Sanofi under a global collaboration agreement.
DUPIXENT is a prescription medicine used:
- to treat adults with moderate-to-severe atopic dermatitis (eczema) that is not well controlled with prescription therapies used on the skin (topical), or who cannot use topical therapies. DUPIXENT can be used with or without topical corticosteroids. It is not known if DUPIXENT is safe and effective in children with atopic dermatitis under 18 years of age.
- with other asthma medicines for the maintenance treatment of moderate-to-severe asthma in people aged 12 years and older whose asthma is not controlled with their current asthma medicines. DUPIXENT helps prevent severe asthma attacks (exacerbations) and can improve your breathing. DUPIXENT may also help reduce the amount of oral corticosteroids you need while preventing severe asthma attacks and improving your breathing. DUPIXENT is not used to treat sudden breathing problems. It is not known if DUPIXENT is safe and effective in children with asthma under 12 years of age.
IMPORTANT SAFETY INFORMATION FOR U.S. PATIENTS
Do not use if you are allergic to dupilumab or to any of the ingredients in DUPIXENT®.
Before using DUPIXENT, tell your healthcare provider about all your medical conditions, including if you:
- have eye problems (if you also have atopic dermatitis)
- have a parasitic (helminth) infection
- are taking oral, topical, or inhaled corticosteroid medicines. Do not stop taking your corticosteroid medicines unless instructed by your healthcare provider. This may cause other symptoms that were controlled by the corticosteroid medicine to come back.
- are scheduled to receive any vaccinations. You should not receive a "live vaccine" if you are treated with DUPIXENT.
- are pregnant or plan to become pregnant. It is not known whether DUPIXENT will harm your unborn baby.
- are breastfeeding or plan to breastfeed. It is not known whether DUPIXENT passes into your breast milk.
Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins and herbal supplements. If you are taking asthma medicines, do not change or stop your asthma medicine without talking to your healthcare provider.
DUPIXENT can cause serious side effects, including:
- Allergic reactions (hypersensitivity), including a severe reaction known as anaphylaxis. Stop using DUPIXENT and tell your healthcare provider or get emergency help right away if you get any of the following symptoms: breathing problems, fever, general ill feeling, swollen lymph nodes, swelling of the face, mouth and tongue, hives, itching, fainting, dizziness, feeling lightheaded (low blood pressure), joint pain, or skin rash.
- Eye problems. If you have atopic dermatitis, tell your healthcare provider if you have any new or worsening eye problems, including eye pain or changes in vision.
- Inflammation in your blood vessels: Rarely, this can happen in people with asthma who receive DUPIXENT. This may happen in people who also take a steroid medicine by mouth that is being stopped or the dose is being lowered. It is not known whether this is caused by DUPIXENT. Tell your healthcare provider right away if you have: rash, shortness of breath, persistent fever, chest pain, or a feeling of pins and needles or numbness of your arms or legs.
The most common side effects include injection site reactions, pain in the throat (oropharyngeal pain) and cold sores in your mouth or on your lips. Eye and eyelid inflammation, including redness, swelling and itching have been seen in patients who have atopic dermatitis.
Tell your healthcare provider if you have any side effect that bothers you or that does not go away. These are not all the possible side effects of DUPIXENT. Call your doctor for medical advice about side effects. You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch, or call 1-800-FDA-1088.
Use DUPIXENT exactly as prescribed. If your healthcare provider decides that you or a caregiver can give DUPIXENT injections, you or your caregiver should receive training on the right way to prepare and inject DUPIXENT. Do not try to inject DUPIXENT until you have been shown the right way by your healthcare provider. In adolescents with asthma 12 years of age and older, it is recommended that DUPIXENT be administered by or under supervision of an adult.
