Kyowa Kirin and MEI Pharma Announce Topline Data from the Phase 2 MIRAGE Study Evaluating Zandelisib in Patients with Indolent B-cell non-Hodgkin’s Lymphoma in Japan

- Interim data from Phase II Study of Zandelisib shows 75.4% ORR in Japanese patients with Indolent B-cell NHL -

- Publication of results from additional Phase 1 study now available in International Journal of Hematology -

Kyowa Kirin Co., Ltd. (Kyowa Kirin, TSE: 4151), a global specialty pharmaceutical company creating innovative medical solutions utilizing the latest biotechnology and MEI Pharma, Inc. (NASDAQ: MEIP), a late-stage pharmaceutical company focused on advancing new therapies for cancer, today announced topline data from the Phase 2 MIRAGE study evaluating zandelisib, an orally administered investigational phosphatidylinositol 3-kinase delta ("PI3Kδ") inhibitor, in patients with indolent B-cell Non-Hodgkin’s Lymphoma (iB-NHL) without small lymphocytic lymphoma (SLL), lymphoplasmacytic lymphoma (LPL), and Waldenström's macroglobulinemia (WM) in Japan.

The data demonstrated a 75.4% objective response rate (ORR) and 24.6% of patients achieved a complete response (CR) as determined by Independent Review Committee (IRRC) assessment (n=61). The data is currently insufficiently mature to accurately estimate duration of response (DOR). With 9.5 months median duration of follow-up, a discontinuation rate due to any treatment emergent adverse event was 14.8%.

“We are very pleased to announce the data from Phase 2 MIRAGE study,” said Yoshifumi Torii, Ph.D., Executive Officer, Vice President, Head of R&D Division of Kyowa Kirin. “We continue to see a favorable profile of zandelisib with intermittent dosing that aims to balance efficacy and safety in Japanese patients who have been heavily pre-treated. These results are consistent with the data of the similarly designed TIDAL study already announced in November 2021. We remain committed to maximizing the value of zandelisib in B-cell malignancies with our partner MEI Pharma and bringing hope to lymphoma patients around the world.”

“The results from the MIRAGE study announced today are not only consistent with the data from the Phase 2 TIDAL study, but support the potential of zandelisib on the intermittent schedule to also provide a high rate of response and low rate of Grade 3 or greater adverse events in Japanese patients with indolent B-cell non-Hodgkin lymphoma,” said Richard Ghalie, M.D., chief medical officer of MEI Pharma.

MIRAGE Study Details

The MIRAGE study is a multicenter, open-label, single-arm Phase 2 trial evaluating zandelisib as monotherapy for Japanese patients with relapsed or refractory (r/r) iB-NHL who received at least two prior systemic therapies (NCT04533581).

A total of 61 patients were enrolled and the median age of patients was 70 years old. Enrolled patients were generally heavily pretreated; the median number of prior therapies was 3 (range 2-9). The primary efficacy endpoint is ORR as assessed by IRRC using a modified Lugano criteria. Patients were administered zandelisib 60 mg once daily for two 28-day cycles as response induction therapy, followed thereafter by 60 mg once daily dosing for the first seven days of each subsequent 28-day cycle, a schedule called Intermittent Dosing Therapy.

Efficacy

The primary endpoint of ORR of zandelisib as a single agent was 75.4% (95% CI [62.7, 85.5]), as assessed by IRRC; the complete response rate was 24.6% (95% CI [14.5, 37.3]). As of the data cutoff date, the data are not sufficiently mature to accurately estimate the final DOR.

Safety and Tolerability

With a median follow-up of 9.5 months (95%CI [8.0, 11.1]), 14.8% of patients discontinued therapy due to any treatment emergent adverse event. Grade 3 adverse events of special interest (AESI) were AST and ALT elevation in 8.2% of patients, rash in 3.3%, and 1.6% each for diarrhea, colitis and lung infection.

Phase 1 Study

We also recently announced the publication of data from the Phase 1 study of zandelisib in Japanese patients with r/r iB-NHL in the International Journal of Hematology (NCT03985189). The publication, entitled "Zandelisib (ME-401) in Japanese patients with relapsed or refractory indolent non-Hodgkin’s lymphoma: an open-label, multicenter, dose-escalation phase 1 study" is available on the journal website.

The publication reported a 100% (N=9) ORR and that 22.2% (N=2) of patients achieved CR starting on a continuous daily schedule (45 or 60 mg); patients could be switched to intermittent dosing for an adverse event. No dose-limiting toxicities were observed in the first cycle of therapy, and the maximum tolerated dose was not reached. With 17.5 months median duration of follow-up, zandelisib was generally well tolerated at 60 mg resulting in the recommended phase 2 dose in Japanese patients.

About Zandelisib

Zandelisib, a selective PI3Kδ inhibitor, is an investigational cancer treatment being developed as an oral, once-daily, treatment for patients with B-cell malignancies. Clinical trials are investigating the efficacy and safety of zandelisib as a single agent and in combination with other modalities while administered on an Intermittent Dosing regimen (ID) and in a time-limited manner when dosed in combination. The ID leverages molecular and biologic properties specific to zandelisib.

In November 2021, MEI Pharma and Kyowa Kirin announced topline data from ongoing Phase 2 TIDAL study (NCT03768505) evaluating zandelisib as a single agent for follicular lymphoma (FL) patients who received at least two prior systemic therapies. Zandelisib demonstrated a 70.3% objective response rate (ORR) as determined by an Independent Review Committee (IRRC) assessment in the primary efficacy population (n=91). In addition, 35.2% of patients achieved a complete response. At the time of the data cutoff, the data were insufficiently mature to accurately estimate duration of response (DOR). In line with previously reported data from the Phase 1B study, zandelisib was generally well tolerated. With 9.4 months (range: 0.8-24) median duration of follow-up in the total study population (n=121), interim data demonstrated a discontinuation rate due to any drug related adverse event of 9.9%. Patients enrolled in the study will continue to be followed for safety and DOR.

Other ongoing studies include the Phase 3 COASTAL study (NCT04745832), comparing zandelisib plus rituximab to standard of care chemotherapy plus rituximab in patients with r/r FL or MZL who received more than one prior line of therapy, which must have included an anti-CD20 antibody in combination with chemotherapy or lenalidomide. COASTAL, which is also evaluating time-limited intermittent administration of zandelisib, is intended to support marketing applications in the U.S. and globally.

In March 2020, the FDA granted zandelisib Fast Track designation for the treatment of adult patients with r/r follicular lymphoma who have received at least two prior systemic therapies. In November 2021, the FDA granted zandelisib Orphan Drug designation for the treatment of patients with follicular lymphoma.

In April 2020, MEI and Kyowa Kirin entered a global license, development, and commercialization agreement to further develop and commercialize zandelisib. MEI and Kyowa Kirin will co-develop and co-promote zandelisib in the U.S., with MEI booking all revenue from the U.S. sales. Kyowa Kirin has exclusive commercialization rights outside of the U.S.
