Promius Pharma™ Receives FDA Approval for Sernivo (betamethasone dipropionate) Spray, 0.05%

HYDERABAD, India & PRINCETON, N.J.–(BUSINESS WIRE)–Dr. Reddy’s announced today that its US subsidiary, Promius PharmaTM,
LLC, U.S. (BSE: 500124, NSE: DRREDDY, NYSE: RDY), has received approval
for Sernivo™ (betamethasone dipropionate) Spray, 0.05% from the U.S.
Food and Drug Administration (FDA). Sernivo Spray, a prescription
topical steroid, is indicated for the treatment of mild to moderate
plaque psoriasis in patients 18 years of age or older. The commercial
launch of the product is planned for the coming quarter.

Commenting on the approval, G V Prasad, Co-Chairman and CEO, Dr. Reddy’s
Laboratories said, “The FDA approval of Sernivo Spray is a significant
milestone for Promius, as it validates our committed efforts and
resources to developing differentiated dermatology products from concept
to commercial launch. We are delighted to receive a first round FDA
approval of Sernivo Spray as we look to expand our portfolio of medical
dermatology products available in the US market.”

Promius has conducted two successful multi-center, randomized,
double-blind, vehicle-controlled clinical trials in subjects aged 18
years and older with moderate plaque psoriasis to evaluate the safety
and efficacy of Sernivo Spray. In both trials, randomized subjects
applied Sernivo Spray or vehicle spray to the affected areas twice daily
for 28 days. Enrolled subjects had body surface area of involvement
between 10% to 20%, and an Investigator Global Assessment (IGA) score of
3 (moderate). Efficacy was assessed as the proportion of subjects who
were considered a treatment success (defined as having an IGA score of 0
or 1 [clear or almost clear] and at least a 2-scale reduction from
baseline). Treatment success was achieved in significantly more subjects
using Sernivo than Vehicle at both Day 15 and Day 29 across both
studies. At Day 29 in Studies 1 and 2, Sernivo achieved treatment
success of 42.7% and 34.5% compared to vehicle success rates of 11.7%
and 13.6%, respectively (p<0.001).

Raghav Chari, Executive Vice President of Proprietary Products at Dr.
Reddy’s and President of Promius Pharma said, “As an emerging leader in
the dermatology space, we are committed to developing innovative
treatment options and support services for clinicians and patients. The
approval of Sernivo emphasizes our ongoing efforts and we look forward
to a successful launch of Sernivo Spray in the coming quarter.”
