CRISPR Therapeutics, a leader in gene therapy, achieved a milestone with the FDA's approval of its Casgevy product for sickle cell disease, marking the first CRISPR-based therapy. Despite a promising pipeline and $1.9 billion in cash, the company faces challenges with slow commercialization and minimal revenue from Casgevy, which has only reached one patient so far. As it prepares for expanded indications and updated efficacy data by 2025, investors remain cautious amid a 46% drop in share value from its 52-week high.
