Sanofi's (SNY) Dupixent Prurigo Nodularis NDA Gets Priority Tag

Read MoreHide Full Article

Sanofi (SNY - Free Report) and partner Regeneron (REGN - Free Report) announced that the FDA has accepted their supplemental Biologics License Application (BLA) seeking label expansion of their blockbuster medicine, Dupixent (dupilumab) for treating adult patients with uncontrolled prurigo nodularis, a chronic inflammatory skin disease. The FDA has also granted priority review to the NDA, shortening its review period from the standard 12 months to 8 months.

The sBLA is supported by data from two pivotal studies — PRIME and PRIME2 — which evaluated efficacy and safety of Dupixent in adult patients with prurigo nodularis.

The top-line data from the PRIME study showed that 60% of the patients treated with Dupixent experienced a clinically meaningful reduction in itch from baseline compared with 18% of the patients in the placebo arm — the primary endpoint. Also, 48% of the patients treated with Dupixent achieved clear or almost clear skin compared to 18% of placebo patients at week 24.

The top-line data from the phase III PRIME2 study showed that 37% of the patients who were treated with Dupixent experienced a clinically meaningful reduction in itch from baseline as compared to 22% of patients in the placebo arm — the primary endpoint. The data also showed that 58% of patients who received Dupixent experienced a clinically meaningful reduction in itch from baseline versus 20% of patients who received placebo at week 24 of treatment. Also, 45% of the patients who were treated with Dupixent achieved clear or almost clear skin compared to 16% of placebo patients at week 24.

Data from the studies demonstrates that Dupixent has the potential to significantly improve disease signs and symptoms compared to placebo, including a reduction in itch and skin lesions.

A decision from the FDA regarding the approval of the label expansion of the drug to include adult prurigo nodularis patients is expected in September. A potential approval can be much earlier than September as the FDA approved a label expansion of the drug to include eosinophilic esophagitis patients within one and a half months of acceptance of the sBLA for the same. Dupixent is now the first and only medicine indicated for eosinophilic esophagitis in the United States, following its approval earlier this month.

Prurigo nodularis will be the fifth FDA-approved disease indication for Dupixent following a potential approval. Sanofi and Regeneron’s Dupixent is already approved in the United States, EU and some other countries for three type II inflammatory diseases, namely for certain patients with chronic rhinosinusitis with nasal polyposis, asthma and atopic dermatitis in different age populations. Dupixent is under review in Europe for eosinophilic esophagitis.

Sanofi stock has risen 10.1% this year so far compared with the industry’s increase of 6.5%.

Dupixent is being jointly marketed by Regeneron and Sanofi under a global collaboration agreement. Sanofi records global net product sales of Dupixent while Regeneron records its share of profits/losses in connection with the global sales of the drug.

Dupixent sales are now annualizing at close to €6.0 billion after around three years on the market. Sanofi expects Dupixent to achieve more than €13 billion in peak sales.  The drug’s frequent label expansion approvals are driving sales higher. With outside U.S. revenues accelerating and multiple approvals for new indications and expansion in younger patient populations expected in the near future, its sales are expected to be higher.

Sanofi and Regeneron are also studying dupilumab in late-stage studies in a broad range of diseases, driven by type II inflammation like bullous pemphigoid, chronic spontaneous urticaria, prurigo nodularis, and chronic obstructive pulmonary disease.
