Helsinn will retain the right to co-promote Pracinostat in the province of Shanghai, China, alongside MENARINI, who will exclusively access the rest of China. Pursuant to certain clauses of the agreement, MENARINI will have the opportunity to exploit any potential further oncology indication in the same territories.

Riccardo Braglia, Helsinn Group Vice Chairman and CEO, said: “We are pleased to have signed this agreement with Menarini, granting them exclusive licensing rights to promote and sell Pracinostat in AML, the prognosis of which remains dismal in those patients unfit to intensive induction chemotherapy.
