Longer-acting Botox maker says demand is seeing a spike

New York

PATIENTS are already clamouring for "the longer-acting Botox", a not-yet approved treatment from Revance Therapeutics, CEO Dan Browne told Bloomberg News.

The launch won't happen for another two years or so, and while many patients want more time looking younger, doctors are looking for a longer-acting product for therapeutic goals.

RT002, as the drug is known, is still in late-stage testing for its first indication - expected to be glabellar lines - for which results are not expected until the second half of this year, with a possible product launch in 2020.

"People underestimate the power of this data," Mr Browne said, expecting it to be a "major de-risking event" for Revance when results from the study, known as "Sakura", are read out later this year.

Revance is targeting an FDA label to show the RT002, a botulinum toxin similar to Allergan's Botox, lasts up to six months, compared to a three- to four-month label claim for Allergan's best-selling product.

The company says it has data that proves the six-month duration claim, said chief operating officer Abhay Joshi, a former 18-year veteran with Allergan. Revance sees this as a "performance product" and will seek "premium pricing", Mr Browne said. He plans to look at annual costs of RT002 over the cost of a single treatment. The company also announced at its investor day that it would target developing RT002 for migraines. BLOOMBERG
