41.3% CR
16.2% PR
Additional results include:
Median duration of response (DoR) was not reached after a median follow up of 44.0 months.
The median overall survival was 33.5 months and median progression-free survival was 11.6 months.
Patients with one pLoT (n = 40) had a higher ORR of 67.5% (CR = 52.5% and PR = 15%).
Benefits for Patients

Tafasitamab has been approved for marketing in Hong Kong and approval for use in Bo’ao and the Greater Bay Area. In Mainland China,patient enrollment of the registrational trial of tafasitamab in combination with lenalidomide was completed in China. The Company expects to submit the biologics license application (BLA) in the second quarter of 2024.

Thanks to the early access program in Bo’ao, the first prescription of tafasitamab in combination with lenalidomide was filed in July, 2022, bringing hope to DLBCL patients in China.
