  • Research and development expenses increased to $94.3 million for the nine months ended September 30, 2025, up from $47.6 million year-over-year, driven by higher preclinical and manufacturing costs.

  • General and administrative expenses decreased to $30.9 million for the nine months ended September 30, 2025, from $32.8 million in the prior year, mainly due to lower stock-based compensation.

One of the very few apps you could call perfect. If something was to add to it, maybe the share price of the company when you search for it, but it's already excellent.
