Cumberland Pharmaceuticals Inc. (NASDAQ: CPIX), a U.S. specialty pharmaceutical company, announced today the launch of RediTrex® (methotrexate) injection. RediTrex is a new line of pre-filled syringes specifically designed for ease of handling and dosing accuracy for the subcutaneous administration of methotrexate in patients with arthritis and psoriasis.
"The RediTrex product line offers patients an important new choice in convenience, safety and dosing accuracy for their methotrexate therapy," said A.J. Kazimi, Chief Executive Officer of Cumberland Pharmaceuticals.
RediTrex is FDA approved for patients with severe, active rheumatoid arthritis and polyarticular juvenile idiopathic arthritis who have difficulty tolerating or responding to orally delivered methotrexate. It is also approved for symptomatic control of severe, recalcitrant, disabling psoriasis in adults who are not adequately responsive to other forms of therapy.
Arthritis is the most common cause of disability in the U.S., with an estimated 52 million Americans having some form of the disease. While there is no cure for most forms of arthritis, the treatment seeks to manage the disease symptoms1. Methotrexate (MTX) is the standard treatment for rheumatoid arthritis as a monotherapy or in combination with other disease-modifying antirheumatic drugs and biologic agents2. The oral form of MTX is typically the first line of treatment for rheumatoid arthritis. As disease progression occurs, the dose of oral MTX must be increased to stay effective, often causing intolerable gastrointestinal side effects. Injectable MTX has been proven to be more effective than oral MTX, with fewer gastrointestinal side effects. Because of the increased efficacy and tolerability, injectable MTX can delay the need to move to costly biologics, lowering overall patient treatment costs3. Once disease progression requires the use of biologics, continuing the treatment of injectable MTX along with the biologic has been shown to increase overall efficacy.
Current injectable MTX options available may not optimally meet the needs of an arthritis patient. Patients are offered either a vial and syringe for self-injection or the use of an expensive autoinjector. The vial and syringe method can be difficult for a patient to handle due to limited dexterity in their hands. In addition, obtaining the exact dose needed while preventing skin exposure to the caustic MTX can be quite challenging. The autoinjectors provide a better alternative to the vial and syringe but they remove injection control from the patient and can be painful to administer. They also resemble biologic autoinjectors, potentially causing confusion, and are more costly.
RediTrex has been designed to be the injectable MTX delivery system that optimally meets the needs of rheumatoid arthritis patients. RediTrex pre-filled syringes assure accurate safe dosing with an automatic retractable needle to reduce the risk of needle sticks. Each syringe is designed for ease of handling and has a large grip and concave plunger that allows patients with limited dexterity to self-administer at a controlled speed. The presentation also limits the possible confusion with biologic pens. In addition, RediTrex uses an extra-thin 29 gauge needle to reduce the pain of each administration. Lastly, RediTrex provides these benefits while being less expensive than autoinjectors.
RediTrex will be launched in two phases. Initial activity will focus on a limited number of centers and physicians as the organization gains insight into information needs and required patient support. During the first quarter of 2021, the second phase will expand activities to a full national launch to the Rheumatology market.
