Research and development, or R&D, revenue for the three and six months ended June 30, 2026 decreased compared to the same periods in 2025 due to the $280 million upfront payment we earned for the global license of sapablursen to Ono Pharmaceutical Co., Ltd.

Restructuring and cost reductionsnegative · 1 filings
