The U.S. Food and Drug Administration approved Adzynma, the first recombinant (genetically engineered) protein product indicated for prophylactic (preventive) or on demand enzyme replacement therapy (ERT) in adult and pediatric patients with congenital thrombotic thrombocytopenic purpura (cTTP), a rare and life-threatening blood clotting disorder.
“The FDA remains deeply committed in our efforts to help facilitate the development and approval of safe and effective therapies for patients with rare diseases,” said Peter Marks, M.D., Ph.D., director of the FDA’s Center for Biologics Evaluation and Research. “Without treatment, cTTP is ultimately fatal. Today’s approval reflects important progress in the development of much-needed treatment options for patients affected by this life-threatening disorder.”
The very rare, inherited blood clotting disorder called cTTP is caused by a disease-causing mutation in the ADAMTS13 gene, which is responsible for making an enzyme, also named ADAMTS13, that regulates blood clotting. A deficiency in this enzyme causes blood clots to form in the small blood vessels throughout the body. It is estimated that cTTP affects fewer than one thousand people in the United States. Symptoms typically develop in infancy or early childhood, but in some cases may develop in adulthood and may first manifest during pregnancy. Individuals with cTTP may experience severe bleeding episodes, strokes and damage to vital organs. If left untreated, the disease can be fatal. Treatment for cTTP typically involves prophylactic plasma-based therapy for individuals with chronic disease to reduce the risk of clotting/bleeding by replenishing the absent/low ADAMTS13 enzyme.
Adzynma is a purified recombinant form of the ADAMTS13 enzyme that works by providing a replacement for the low levels of the deficient enzyme in patients with cTTP. For prophylactic ERT, Adyznma is administered to help reduce the risk of disease symptoms. The product may also be administered as an on-demand ERT for treatment when the patient is experiencing an acute event. Adzynma is administered intravenously once every other week for prophylactic ERT, and once daily for on-demand ERT.
The safety and effectiveness of Adzynma were demonstrated in a global study evaluating prophylactic and on-demand ERT with Adzynma compared to plasma-based therapies in patients with cTTP.
The efficacy of Adzynma in the prophylactic treatment of patients with cTTP was evaluated in 46 patients who were randomized to receive 6 months of treatment with either Adzynma or plasma based therapies (Period 1), then crossed over to the other treatment for 6 months (Period 2). The efficacy was demonstrated based on the incidence of thrombotic thrombocytopenic purpura (TTP) events, and TTP manifestations, as well as the incidence of the need for supplemental doses.
The efficacy of on demand ERT was evaluated based on the proportion of acute TTP events responding to Adzynma in both the prophylactic and the on-demand cohorts throughout the duration of the study. All acute and subacute TTP events resolved after treatment with either Adzynma or plasma based therapies.
The most common side effects associated with Adzynma include headache, diarrhea, migraine, abdominal pain, nausea, upper respiratory tract infection, dizziness and vomiting. During the clinical studies, no adverse events, including allergic reactions, were observed during the administration of Adzynma.
The FDA granted approval of Adzynma to Takeda Pharmaceuticals U.S.A. Inc.
Salmonella Outbreak: Cantaloupe Recall Investigation

FDA Approves Interchangeable Biosimilar for Multiple Inflammatory Diseases
Today, the U.S. Food and Drug Administration approved Wezlana (ustekinumab-auub) as a biosimilar to and interchangeable with Stelara (ustekinumab) for multiple inflammatory diseases. Wezlana, like Stelara, is approved to treat the following indications:
Adult patients with:
- moderate to severe plaque psoriasis who are candidates for phototherapy or systemic therapy;
- active psoriatic arthritis;
- moderately to severely active Crohn’s disease; and
- moderately to severely active ulcerative colitis.
Pediatric patients 6 years of age and older with:
- moderate to severe plaque psoriasis who are candidates for phototherapy or systemic therapy; and
- active psoriatic arthritis.
Health care professionals should review the prescribing information in the labeling for detailed information about the approved uses.
“Biosimilar medications offer additional safe and effective treatment options that have the potential to increase access for people requiring treatment for inflammatory diseases,” said Nikolay Nikolov, M.D., director of the Office of Immunology and Inflammation in the FDA’s Center for Drug Evaluation and Research. “Today’s approval could have a meaningful impact for patients managing their disease.”
Biological products include medications for treating many serious illnesses and chronic health conditions. A biosimilar is a biological product that is highly similar to, and has no clinically meaningful differences from, a biological product already approved by the FDA (also called the reference product). An interchangeable biosimilar is a biosimilar that has been shown to meet other requirements under the law and may be substituted for the reference product without consulting the prescriber. The substitution may occur at the pharmacy, subject to state pharmacy laws which vary by state, a practice commonly called “pharmacy-level substitution” — similar to how generic drugs are substituted for brand name drugs.
All biological products are approved only after they meet the FDA’s rigorous approval standards. This means health care providers and patients can expect the same safety and effectiveness from both a biosimilar and an interchangeable biosimilar, just as they would for a reference product. Biosimilar and interchangeable biosimilar products may cost less than the brand-name medicine.
“Today’s approval exemplifies the FDA’s longstanding commitment to support a competitive marketplace for biological products,” said Sarah Yim, M.D., director of the Office of Therapeutic Biologics and Biosimilars in the FDA’s Center for Drug Evaluation and Research. “This approval can empower patients by helping to increase access to safe, effective and high-quality medications at potentially lower cost.”
The FDA’s approval of Wezlana is based on a comprehensive review of scientific evidence demonstrating it is highly similar to Stelara and that there are no clinically meaningful differences between the two products in terms of safety, purity and potency (i.e., safety and effectiveness). This evidence included comparisons of the products on an analytical level using an extensive battery of chemical and biological tests and biological assays that confirmed similarity in the structural and functional features of Wezlana and Stelara (including those known to impact safety and efficacy), and comparative human pharmacokinetic data, clinical immunogenicity data, and other clinical safety and effectiveness data. The evidence also demonstrated that Wezlana met the other legal requirements to be interchangeable with Stelara at the pharmacy level.
Like Stelara, the most serious known side effect of Wezlana is infection. The most common adverse reactions with ustekinumab products are nasopharyngitis, upper respiratory tract infection, headache, fatigue, nausea, vomiting, injection site erythema, vulvovaginal candidiasis/mycotic infection, bronchitis, pruritus, urinary tract infection, sinusitis, abdominal pain, influenza, fever and diarrhea.
The labeling for Wezlana, like Stelara, contains a warning to alert health care professionals and patients about an increased risk of serious infections leading to hospitalization. There is also a warning that some malignancies, hypersensitivity reactions, and cases of Posterior Reversible Encephalopathy Syndrome have been reported in patients who received Wezlana in clinical studies. Wezlana must be dispensed with a patient Medication Guide that describes important information about its uses and risks.
The FDA granted the approval of Wezlana to Amgen, Inc.
