Sarepta Therapeutics Inc (NASDAQ:SRPT) shares are down nearly 3% to $31.40 in pre-market trading, following a statement from Jefferies’ key opinion leader (KOL) regarding yesterday’s news that Dr. Ronald Farkas, the lead on a critical FDA review of Sarepta’s eteplirsen for Duchenne muscular dystrophy (DMD), is leaving his position. His departure is viewed by investors as a good sign for a potential approval. However, the KOL believes there’s no change to Eteplirsen approvability.

Jefferies lead analyst Gena Wang noted, “We hosted a call with an FDA regulatory expert on the departure of FDA former agent Dr. Farkas (clinical team leader for eteplirsen review) and its potential impact on the approval process for eteplirsen. Our KOL sees no changes on the probability of approval and believes longer delay suggests a tougher path to approval. We continue to see low probability of approval for eteplirsen.”

Wang reiterated an Underperform rating on shares of Sarepta, with a $7.00 price target, which reflects a potential downside of -78% from last closing price.
