Promising data
Commenting on the study, Karissa Gable, MD, an associate professor of neurology at Duke University, Durham, N.C., said that the “initial data reported from the ADHERE study is very promising and demonstrated significant efficacy.”
The study’s use of an adjudication committee in confirming the diagnosis is particularly notable, she said. “The trial design demonstrated confirmation of diagnosis and activity of disease and response to drug prior to randomization, which is a novel design that is particularly applicable to patients with CIDP given the rate of misdiagnosis and placebo effect found in other trials.”
Dr. Gable agreed that new options are important to address an unmet need in CIDP.
“The current first-line treatments are generally 80%-90% effective, however, there are limited options with respect to the first line treatments due to side effects and comorbid disease in patients,” she explained.
“Other treatments options are needed and so this is an unmet need in patients with CIDP,” Dr. Gable said. “This medication will be likely to be one that will provide a strong alternate option for treatment.”
Overall, “this is a novel mechanism for drug treatment for CIDP and seems to demonstrate efficacy and good safety and tolerability based on the initial report of the data,” Dr. Gable added.
“It will likely be a promising medication to use for these patients to fill the unmet need for treatment of patients with CIDP.”
The study was sponsored by Argenx. Dr. Lewis disclosed relationships with Argenx and other companies involved in neuromuscular disease therapies. Dr. Gable is on the global medical advisory board steering committee for Argenx and she was the principal investigator at her site for the Adhere study. Dr. Gable has served as a consultant for Immunovant and Takeda as well as Sanofi for CIDP and she is on the Takeda speaker bureau for Huyquvia for treatment of CIDP.
