Antineoplastic agents
Released "Jaypirca Tablets 50 mg, Jaypirca® Tablets 100 mg"®

Nippon Shinyaku Co., Ltd. (Nippon Shinyaku; Headquarters: Kyoto; President: Toru Nakai) and Eli Lilly
Japan K.K. (Eli Lilly Japan; Headquarters: Kobe; President and Representative Director: SimoneThomsen) announced that the antineoplastic agents "Jaypirca® 50 mg and 100 mg tablets" (genericname: pirtobrutinib; hereinafter referred to as "Jaypirca") was listed on the NHI price list on August 15,2024, and was launched today, August 21, 2024.
Jaypirca is a Bruton tyrosine kinase (BTK) inhibitor that binds reversibly and noncovalently to BTK. BTK
is recognized as a target for a variety of B-cell lymphomas, including mantle cell lymphoma (MCL), andleukemia, including chronic lymphocytic leukemia (CLL).1,2
Approval of Jaypirca is based on the efficacy and safety results of Study BRUIN-18001, a global Phase
1/2 study. In this study, the efficacy and safety of Jaypirca were evaluated in patients with relapsed or
refractory MCL who were resistant or intolerant to other covalent BTK inhibitors. The centrally assessed
overall response rate, the primary endpoint, was 56.9% (95% confidence interval: 44.0, 69.2). The mostcommon adverse drug reactions were fatigue, diarrhea, bruising, dyspnea, muscle pain, platelet countdecreased, anemia, and cough.
Based on the alliance agreement concluded in March 2024, Eli Lilly Japan will be responsible for supplyof Jaypirca in Japan, while Nippon Shinyaku will be responsible for distribution and sales, as well as
information provision activities.
We believe that Jaypirca will become a new treatment option for MCL and can meet the unmet medical
needs of MCL patients, and will play a role in each company.

About the Global Phase 1/2 Study (BRUIN-18001)※
In the BRUIN-18001 trial, patients with relapsed or refractory mantle cell lymphoma who were resistantor intolerant to other covalent BTK inhibitors were randomized to receive Jaypirca 200 mg1 orally once
daily. Among 65 patients in the primary efficacy analysis population2, the centrally assessed overall
response rate, the primary endpoint, was 56.9% (95% confidence interval: 44.0, 69.2). The overall
response rate in 8 Japanese patients3 was 50.0% (95% confidence interval: 15.7, 84.3). Among 15
patients with blastoid mantle cell lymphoma previously treated with other covalent BTK inhibitors, theoverall response rate was 46.7% (95% confidence interval: 21.3, 73.4).*
Adverse drug reactions were reported in 104 (63.4%) of 164 subjects1, 4 in the safety analysis population.
The most common adverse drug reactions were fatigue (22.0%), diarrhea (12.2%), bruising (9.8%),
dyspnea (9.1%), muscle pain (8.5%), platelet count decreased (6.7%), anemia (6.1%), and cough (6.1%).
Note 1: Included patients whose starting dose of Jaypirca was not 200 mg.
Note 2: Among patients with non-blastoid mantle cell lymphoma previously treated with other covalent BTK inhibitors, up
to 65 patients in the order of initiation of treatment were included in the primary efficacy analysis population.
Note 3: Among Japanese patients with non-blastoid mantle cell lymphoma previously treated with other covalent BTK
inhibitors, up to 8 patients in the order of initiation of treatment were included in the primary efficacy analysis population.
Note 4: All patients with mantle cell lymphoma who received at least one dose of Jaypirca alone.
* The analysis was performed at the request of regulatory authorities after filing the application for marketing approval.

About Mantle Cell Lymphoma
MCL is a rare blood cancer and a form of non-Hodgkin lymphoma. MCL arises in B lymphocytes, a typeof white blood cell. MCL frequently begins in B cells located in the mantle zone of the outer edge oflymph nodes. As the cancer progresses, it can spread to bone marrow, the spleen, the liver, or the digestive tract.3 Annually, about one in 200,000 people worldwide develop MCL3.
