EWING, N.J., March 29, 2016 (GLOBE NEWSWIRE) -- Antares Pharma, Inc. (NASDAQ:ATRS) today announced the approval by the U.S. Food and Drug Administration (FDA) of three new dosage strengths of OTREXUP™ (methotrexate) injection. The new dosage strengths of 12.5 mg/0.4 ml, 17.5 mg/0.4 ml and 22.5 mg/0.4 ml will complement the already approved and marketed strengths of 7.5 mg/0.4 ml, 10 mg/0.4 ml, 15 mg/0.4 ml, 20 mg/0.4 ml, and 25 mg/0.4 ml. New, interim dose-strength options will enable physicians to select more specific, optimal doses to help achieve patient treatment goals.
“OTREXUP™ has always been available in the most commonly prescribed strengths of methotrexate, but our new interim dose options may provide physicians even more opportunity to give their patients precisely what is needed to achieve disease control,” said Robert Apple, President and Chief Executive Officer of Antares Pharma. “Each and every patient treatment regimen is different, so providing a step approach to therapy may extend and optimize the use of OTREXUP™ for patients. New interim strengths are also covered by OTREXUP™ TotalCare so all eight dosing options are eligible for up to $125 of patient co-pay assistance.”
OTREXUP™ was the first FDA-approved subcutaneous methotrexate for once weekly self-administration with an easy-to-use, single dose, disposable auto injector. OTREXUP™ is indicated for adults with severe active rheumatoid arthritis who have had an insufficient therapeutic response to or are intolerant of an adequate trial of first line therapy including full dose non-steroidal anti-inflammatory agents. In addition, OTREXUP™ is also approved for use in children with active polyarticular juvenile idiopathic arthritis as well as for use in adults for symptomatic control of severe recalcitrant, disabling psoriasis that is not adequately responsive to other forms of therapy.

IMPORTANT SAFETY INFORMATION
OTREXUP™ is a single-dose auto-injector containing a prescription medicine, methotrexate. Methotrexate is used to:
- treat certain adults with severe, active rheumatoid arthritis (RA), and children with active polyarticular juvenile idiopathic arthritis (pJIA), after treatment with other medicines including non-steroidal anti-inflammatory (NSAIDS) have been used and did not work well.
- control the symptoms of severe, resistant, disabling psoriasis in adults when other types of treatment have been used and did not work well.
OTREXUP should not be used for the treatment of cancer.
OTREXUP should not be used for the treatment of children with psoriasis.
Methotrexate includes the following boxed warning:
OTREXUP can cause serious side effects that can lead to death, including:
- Organ system toxicity. People who use methotrexate for the treatment of cancer, psoriasis, or rheumatoid arthritis, have an increased risk of death from organ toxicity. Types of organ toxicity can include: gastrointestinal, bone marrow, liver, immune system, nerve, lung, kidneys and skin.
Your doctor will do blood tests and other types of tests before you take and while you are taking OTREXUP to check for signs and symptoms of organ toxicity. Call your doctor right away if you have any of the following symptoms of organ toxicity: vomiting, diarrhea, mouth sores, fever, confusion, weakness, temporary blindness, seizures, headache, back pain, neck stiffness, paralysis, irritability, sleepiness, and problems with coordination, dry cough, trouble breathing and severe skin rash.
- Women who are pregnant are at increased risk for death of the baby and birth defects. Women who are pregnant or who plan to become pregnant must not take OTREXUP. A pregnancy test should be performed before starting OTREXUP.
Contraception should be used by both females and males while taking OTREXUP. Pregnancy should be avoided if either partner is receiving OTREXUP:
- For a minimum of 3 months after treatment with OTREXUP for males.
- During and for at least 1 menstrual cycle after treatment with OTREXUP for females.
What are the possible side effects of OTREXUP?
OTREXUP may cause serious side effects, including:
See “What is the most important information I should know about OTREXUP?”

- Certain cancers. Some people who have taken methotrexate have had a certain type of cancer called Non-Hodgkin’s lymphoma and other tumors. Your doctor may tell you to stop taking OTREXUP if this happens.
- Tissue and bone problems. Taking Methotrexate while having radiation therapy may increase the risk of your tissue or bone not receiving enough blood. This may lead to death of the tissue or bone.
Common side effects of OTREXUP include: nausea, stomach pain, indigestion (dyspepsia), mouth sores, and rash.
What should I tell my doctor before taking OTREXUP?

About Rheumatoid Arthritis
Rheumatoid arthritis (RA) is a chronic, systemic autoimmune disease characterized by pain and inflammation of the joints. In people with RA, the immune system attacks healthy tissue, specifically the thin membrane that lines the joints, causing swelling that leads to pain and inflammation throughout the body. Over long periods of time, RA can cause damage to cartilage, tendons, or ligaments, leading to joint deformity or disability. Additionally, research shows that people with RA, mainly those whose disease is not well controlled, have a higher risk for heart disease and stroke.
About Polyarticular Juvenile Idiopathic Arthritis
Polyarticular juvenile idiopathic arthritis is a subgroup of juvenile idiopathic arthritis (JIA)[i] in which five or more joints are impacted in children within the first six months after disease onset. JIA occurs in people under the age of 18.
In patients with JIA, the immune system attacks healthy tissue, specifically the thin membrane that lines the joints, causing swelling that leads to pain and inflammation throughout the body. Over long periods of time, arthritis can cause damage to cartilage, tendons or ligaments, leading to joint deformity or disability.
Treatments are available that may help relieve symptoms and reduce inflammation. In addition, disease-modifying antirheumatic drugs (DMARDs) and new biologic agents can modify the disease or slow its progression.
Psoriasis is a chronic autoimmune skin disease that most commonly appears as raised, red patches with a white buildup of dead skin cells. Psoriasis can affect skin on any part of the body and occurs when the immune system sends out faulty signals that speed the growth cycle of skin cells. Psoriasis is considered recalcitrant psoriasis when it does not respond to therapy, and can be disabling.
Psoriasis is generally considered to be severe if it covers more than 5%-10% of body surface, recalcitrant when it does not adequately respond to treatment and disabling when it interferes with basic functions such as self-care, walking, sleep, etc.
