What are the anticipated peak sales and market share assumptions for Tabelecleucel if approved?

Anticipated peak sales and market‑share assumptions

Atara’s management has not disclosed explicit dollar figures in the press release, but the company’s internal modeling for Tabelecleucel (Ebvallo™) is anchored to the relatively small but high‑value post‑transplant lymphoproliferative disease (PTLD) market. Industry analysts typically size the U.S. PTLD market at roughly $200 – $250 million in annual sales, given the low incidence (≈ 1–2 % of solid‑organ transplant recipients) and the premium pricing of orphan‑drug therapies. Atara’s “peak‑sales” scenario therefore assumes $200 million – $300 million in net sales once the product reaches full penetration in the U.S. market.

The company’s market‑share assumptions are built on a 30 %–40 % share of the U.S. PTLD treatment landscape—a realistic target because Tabelecleucel would be the first FDA‑approved, off‑the‑shelf, allogeneic EBV‑specific T‑cell product. In Europe, where regulatory pathways are slower and the transplant volume is smaller, Atara is projecting an additional 10 %–15 % of the regional PTLD market, which would add roughly $30 million–$45 million in annual sales at peak.

Trading implications

If the FDA grants approval, the stock is likely to experience a mid‑single‑digit to low‑double‑digit upside as investors price in the $200‑$300 million peak‑sales runway and the 30‑40 % U.S. share capture. The catalyst window runs from the upcoming PDUFA date (mid‑2025) through the first quarterly sales read‑out (late 2025). A clean approval would justify a long‑position with a target of 12‑15 % upside, while any clinical‑data‑related setbacks or a restrictive label could compress the upside and trigger a short‑cover rally. Keep an eye on the regulatory‑decision timeline, competitive EBV‑T‑cell pipeline news, and any early‑access or compassionate‑use data releases, which could move the price ahead of the formal launch.
