The deal grants First Tracks access to 45,057 square feet of office space previously held by AnaptysBio. According to a filing with the Securities and Exchange Commission, the sublease officially commenced on June 15. The initial term spans 12 months, though the agreement includes a renewal option that could extend occupancy through April 2028.

This real estate transaction follows the company's April spin-out from AnaptysBio, marking a phase of independent operations for the biotech firm. Investors have shown growing interest in the stock, which had already posted a 6.6% gain over the past month prior to the latest announcement.
