Servier and CTI BioPharma Expand License and Collaboration Agreement to Develop and Commercialize PIXUVRI®

Servier and CTI BioPharma Corp. (CTI BioPharma) (NASDAQ and MTA: CTIC) today jointly announced that they agreed to expand their existing license and development collaboration agreement for PIXUVRI^® (pixantrone). Under this expanded agreement, Servier will have rights to PIXUVRI in all markets except the US, where CTI BioPharma will retain the commercialization rights. Servier will pay CTI BioPharma €12 million with the potential for CTI BioPharma to receive €76 million in additional sales and regulatory milestone payments as well as royalties on net product sales.

PIXUVRI has been granted conditional marketing authorization from the European Commission for the treatment of adult patients with multiply relapsed or refractory aggressive non-Hodgkin B-cell lymphoma (NHL).¹ As a specific post-authorization requirement, PIXUVRI is currently being investigated in a Phase III clinical trial, PIX306. If positive, the results from this trial will confirm the treatment’s current indication and could support broader indications.

In 2014, CTI granted Servier rights to commercialize the drug globally except in Austria, Denmark, Finland, Germany, Israel, Norway, Sweden, Turkey, UK and the US. With this expanded agreement, which provides Servier’s rights to all markets except the US, the companies will continue to work closely together to build the efficacy and safety evidence for PIXUVRI and to ensure that as many eligible patients as possible are benefitting from it.

“Over the past three years, we have worked hand in hand with our partner, CTI BioPharma, to bring new treatment options to patients in Europe”, said U. Marion Schrenk, MD, Head of Therapeutic Area Oncology of Servier. “We are looking forward to leveraging our expertise in these additional markets to ensure more eligible patients have access to PIXUVRI. Oncology is an important focus for us, and we are fully committed to working with our partners, researchers and scientists to provide patients with novel therapeutic options in areas with high unmet needs.”

“Servier is an important strategic partner for us and has helped bring PIXUVRI to many patients," said Adam R. Craig, President and CEO of CTI BioPharma. “We look forward to our expanded partnership as we aim to complete the PIX306 trial in the near-term.”

About PIXUVRI (pixantrone)

PIXUVRI is a cytotoxic medicine that works by interfering with the DNA within cells and preventing them from making more copies of DNA. This means that the cancer cells in B-cell NHL cannot divide and eventually die.²

PIXUVRI is conditionally approved in the EU as monotherapy for the treatment of adult patients with multiply relapsed or refractory aggressive B-cell NHL. The benefit has not been established in patients when used as fifth line or greater chemotherapy in patients who are refractory to last therapy.

The Summary of Product Characteristics (SmPC) has the full prescribing information, including the safety and efficacy profile of PIXUVRI in the approved indication. The SmPC is available at www.servier.com.

About NHL

NHL is an uncommon type of cancer that affects the lymphatic system, which is defined as a network of vessels and glands that run throughout the body. ³ The lymphatic system is a key component of the immune system, as it plays a role in destroying old or abnormal cells and fighting bacteria and other infections.⁴

Around 93,500 new cases of NHL were diagnosed in Europe in 2012, making it the eleventh most common cancer on the continent.⁵

NHL comprises more than 60 subtypes, with each requiring a different diagnostic evaluation and treatment approaches. Lymphoma patient groups around the world, led by the umbrella group Lymphoma Coalition, have been recently calling for accurate subtype reporting to allow patients to clearly understand their subtype and have better communication with their doctors. Given the complexities of the condition, access to information is essential to empower patients.
