ImmuneOnco Biopharmaceuticals (Shanghai) (HKG:1541) regained the global rights to IMM2510 and IMM27M after terminating a license agreement with Axion Bio, according to a Hong Kong bourse filing Tuesday.
Shares of the firm fell nearly 1% in morning trade Wednesday.
The termination does not affect the $35 million ImmuneOnco received as upfront and milestone payment from Axion, the firm said.
Both drug candidates were being developed as anti-tumor medicines.
