TORONTO, Sept. 12, 2022 /CNW/ – DRI Healthcare Trust (TSX: DHT.UN) (TSX: DHT.U) ("DRI" or "the Trust") today announced that a wholly-owned subsidiary of DRI has acquired a royalty interest in Zejula from AnaptysBio, Inc. for a purchase price of US$35 million. An additional milestone payment of US$10 million will be paid should Zejula be approved by the U.S. Food and Drug Administration ("FDA") for the treatment of endometrial cancer on or before December 31, 2025.

Zejula is approved by both the FDA and European Medicines Agency ("EMA") as a treatment for both first-line and recurrent ovarian cancer. Additional indications in development include endometrial cancer, HER2-negative breast cancer, non-small cell lung cancer, metastatic castrate-sensitive prostate cancer, as well as metastatic castration-resistant prostate cancer, which was submitted for approval to the EMA in April 2022.

"We are excited to announce the addition of Zejula to our portfolio," said Behzad Khosrowshahi, Chief Executive Officer of DRI Healthcare Trust. "Our expanding expertise in oncology products helped us identify a versatile product with multiple pipeline indications that present significant potential sales growth. This accretive transaction adds another long-term asset, providing immediate cash flows to the Trust with significant growth potential."

The transaction entitles DRI to a net 0.5% royalty on worldwide net sales of Zejula by GSK plc ("GSK"). DRI will be entitled to receive quarterly royalty payments on a one-quarter lag based on sales beginning July 1, 2022 and will receive its first payment in Q4 2022. The royalty term is expected to continue for at least another 10 years worldwide.

Zejula is marketed by GSK worldwide excluding certain Asian territories, for all indications except for prostate cancer, which, pending regulatory approvals, will be marketed by Johnson & Johnson. Takeda Pharmaceutical Company Limited markets Zejula in Japan for all indications, as well as Taiwan and South Korea for all ex-prostate cancer indications. Zai Lab markets Zejula in China.

About Zejula

Zejula is an oral small molecule inhibiting poly-ADP ribose polymerase ("PARP") 1 and PARP2. It is approved in the US, EU, Japan and China for the treatment of ovarian cancer in several settings including first-line maintenance treatment. The PARP family of proteins detects and repairs single strand DNA breaks by the base-excision repair pathway.

About Ovarian Cancer

Ovarian cancer is considered an orphan disease in the US with about 20,000 new diagnoses annually. Ovarian cancer is generally identified and diagnosed at a late stage, since there are no effective screening methods to identify it earlier and the symptoms are non-specific in nature. Primary surgical cytoreduction followed by systemic chemotherapy is the preferred initial management for women with stage III or IV ovarian cancer. After complete or partial response to first line treatment with chemotherapy, patients can be treated with maintenance therapy.
