FDA: Authorities Seize Unapproved Crescendo Therapeutics Drug

For months, Crescendo Therapeutics appears to have been thumbing its corporate nose at the FDA. Last November, the agency warned the little company for failing to maintain a system for collecting adverse event reports for its HybriSil topical treatment for scars. Crescendo offered a novel explanation – side effect reports simply had not been received (back story). Moreover, the FDA upbraided Crescendo for marketing HybriSil in the first place – the product, you see, was never approved.
