Eagle Pharmaceuticals Announces TREAKISYM (bendamustine) Ready-to-Dilute (“RTD”) Formulation, in Combination with Rituximab for Treatment of Relapsed or Refractory Diffuse Large B-cell Lymphoma Receives PMDA Approval in Japan

Eagle Pharmaceuticals, Inc. (“Eagle” or the “Company”) (NASDAQ: EGRX) today announced that TREAKISYM ready-to-dilute (“RTD”) (bendamustine hydrochloride 120 mg/m²) liquid formulation has been approved for a new indication in combination with rituximab (“BR therapy”) as treatment for relapsed or refractory diffuse large B-cell lymphoma (“r/r DLBCL”) by the Pharmaceuticals and Medical Devices Agency (“PMDA”) in Japan.

“This latest approval is another meaningful extension of our bendamustine franchise. We believe this expanded label will significantly increase the market opportunity for TREAKISYM in Japan. Based on this additional indication, as well as the anticipated approval of the ten-minute RI liquid formulation, we are reiterating our belief that the combined royalty and milestones revenue from these products will generate $25 million at peak,” stated Scott Tarriff, Chief Executive Officer.

In September 2017, Eagle licensed to SymBio intellectual property necessary to develop, market and sell RTD and RI formulations of bendamustine under the trade name TREAKISYM in Japan utilizing Eagle’s proprietary technology. As part of the agreement, SymBio assumed responsibility for securing regulatory approval of the TREAKISYM RTD and RI products using the licensed technology in Japan.

SymBio received approval for the TREAKISYM RTD (250 ml) liquid formulation in September 2020 and is currently conducting a clinical safety trial for the ten-minute RI (50 ml) liquid formulation, for which it plans to seek approval in the second half of 2022.

Key benefits to patients and healthcare providers of these products include eliminating the need for manual reconstitution and significantly reducing preparation time as compared to the lyophilized formulation.
