MorphoSys Announces that its Licensee Janssen Has Received U.S. FDA Approval for Tremfya^(R) One-Press Patient-Controlled Injector for Adults with Moderate-to-Severe Plaque Psoriasis
 

MorphoSys AG (FSE: MOR; Prime Standard Segment, MDAX & TecDAX; NASDAQ: MOR) announced today that its licensee Janssen Research & Development, LLC (Janssen), has reported that the U.S. Food and Drug Administration (FDA) has approved Tremfya^(R) (guselkumab) One-Press, a single-dose, patient-controlled injector for adults with moderate-to-severe plaque psoriasis.
 

According to a press release published by Janssen today, Tremfya^(R) is the first FDA-approved medication of its kind to offer the One-Press patient-controlled injector. Tremfya^(R) is intended for use under the guidance and supervision of a physician, and patients may self-inject with Tremfya^(R) One-Press after physician approval and proper training.
 

Tremfya^(R) (guselkumab) is a human anti-IL-23 monoclonal antibody developed by Janssen that was generated utilizing MorphoSys's proprietary HuCAL antibody technology. MorphoSys is eligible to certain milestone payments and receives royalties on net sales of Tremfya^(R).
 

At times, patients living with plaque psoriasis may struggle with self-administering treatments due to a number of factors including needle phobia. In the phase 3, multicenter and randomized ORION study, patient experience with One-Press was assessed through a validated Self-Injection Assessment Questionnaire (SIAQ), which evaluated patient experience at weeks zero, four and twelve on a scale of 0 (worst) to 10 (best) across six domains (feelings about injections, self-image, self-confidence, pain and skin reactions during or after the injection, ease of use of the self-injection device and satisfaction with self-injection). The mean score for "Satisfaction with Self Injection" was 9.18 (with 10 indicating "very satisfied") and the mean score for "Ease of Use" was 9.24 (with 10 indicating "very easy").
 

The efficacy and safety of Tremfya^(R) administered with One-Press in patients with moderate to severe plaque psoriasis was also evaluated in the double-blind, placebo-controlled ORION study. In the study, a greater proportion of subjects in the Tremfya^(R) group achieved an IGA score of 0 or 1 or a PASI 90 response at week 16 (81 percent and 76 percent, respectively) than in the placebo group (0 percent for both endpoints). The proportion of subjects who achieved an IGA score of 0 at week 16 was higher in the Tremfya^(R) group compared to the placebo group (56 percent vs. 0 percent). The proportion of subjects who achieved a PASI 100 response at week 16 was higher in the Tremfya^(R) group compared to the placebo group (50 percent vs. 0 percent). The majority of injection-site reaction symptoms with One-Press were mild and transient in nature.
 

According to Janssen, the design of the Tremfya^(R) One-Press, which is now available in the U.S., is intended to allow patients to control the rate and pressure of their injection. Nearly 99 percent of patients reported a successful first injection in the ORION study. One-Press also includes a safety system intended to protect the needle after use. After three injections, patients still reported favorable outcomes with the usability of the One-Press device in the study.
 

Dr. Markus Enzelberger, Chief Scientific Officer of MorphoSys AG, said: "We are very pleased that our licensee Janssen has received U.S. FDA approval for the Tremfya^(R) One-Press patient-controlled injector based on Janssen's phase 3 ORION study. With this approval, patients will have the option to self-administer their treatment in a simple and more convenient way."
 

Tremfya^(R) (guselkumab) has been approved in the U.S., Canada, the European Union, and several other countries for the treatment of adults with moderate to severe plaque psoriasis and in Japan for the treatment of various forms of psoriasis, psoriatic arthritis, and palmoplantar pustulosis. The agent is currently being investigated in clinical studies in several indications, including plaque psoriasis, pediatric psoriasis, psoriatic arthritis, Crohn's disease, hidradenitis suppurativa, and ulcerative colitis.
