MEI Pharma Reports Third Quarter Fiscal Year 2023 Results and Operational Highlights

-- MEI Begins Fourth Fiscal Quarter with $112.0 Million in Cash --

MEI Pharma, Inc. (Nasdaq: MEIP), a clinical-stage pharmaceutical company focused on advancing new therapies for cancer, today reported results for the quarter ended March 31, 2023, and highlighted recent corporate events.

“We are making steady progress in advancing both of our clinical-stage pipeline programs: voruciclib for hematologic malignancies and ME-344 for relapsed colorectal cancer, both expected to report data by around the end of the calendar year,” said Dan Gold, Ph.D., President and Chief Executive Officer of MEI Pharma. “With the clinical-data expected from these two programs around year-end, funds to support operations for at least two years based upon our current development plans, and the opportunity to further strengthen our value proposition via the pending merger with Infinity Pharmaceuticals, we are well positioned to deliver progress in our mission to deliver improved benefits to patients with cancer, as well as value to our shareholders.”

Third Quarter Fiscal Year 2023 and Recent Developments

• Kyowa Kirin has been evaluating whether to continue developing zandelisib in Japan and after meeting with the PMDA has concluded this month that conducting a randomized study consistent with agency guidance to support a marketing application would likely not be feasible to complete within a time period that would support further investment. As a result, Kyowa Kirin decided to discontinue development of zandelisib in Japan. The discontinuation of zandelisib in Japan was a business decision by Kyowa Kirin based on the most recent regulatory guidance from the PMDA and is not related to the zandelisib clinical data generated to date.
  
  
  
  In light of Kyowa Kirin’s decision to discontinue development of zandelisib in Japan, the parties intend to terminate the global license, development and commercialization agreement executed in April 2020.

• In April 2023, MEI conducted a 1-for-20 reverse stock split. The reverse stock split was approved by MEI’s stockholders on January 5, 2023, and was implemented with the intent to increase the per share trading price of the Company's common stock to enable the Company to satisfy the minimum bid price requirement for continued listing on Nasdaq. As per a notice received from the Nasdaq dated May 2, 2023, MEI regained compliance with the Nasdaq minimum bid requirement.

• In March 2023, the Safety Review Committee of the Phase 1 study evaluating voruciclib, MEI’s orally administered cyclin-dependent kinase 9 (CDK9) inhibitor, plus venetoclax (Venclexta®) completed a safety assessment of the initial dose escalation cohort evaluating the combination in patients with acute myeloid leukemia (AML) and recommended opening the next cohort. The combination stage of the study started after completing the single-agent dose exploration stage of the Phase 1 study in patients with either AML or B-cell malignancies. CDK9 inhibition disrupts Mcl-1 production and upregulation of Mcl-1 is a known escape mechanism of treatment with venetoclax. Thus, the combination being evaluated presents an opportunity to explore the synergistic potential to disrupt the cell cycle and inhibition of pro-survival cell cycle pathways.

• In February 2023, MEI Pharma and Infinity Pharmaceuticals announced a definitive merger agreement for an all-stock transaction pursuant to which Infinity will become a wholly owned subsidiary of MEI Pharma. The combined company would have a projected cash balance of approximately $100 million at Closing that would be expected to fund operations through mid-2025, and to clinical data over the next 12 to 24 months across three clinical-stage oncology development programs: eganelisib, an oral immuno-oncology macrophage reprogramming product candidate, voruciclib, an oral CDK9 inhibitor, and ME-344, a novel tumor selective mitochondrial inhibitor.

Expected Drug Candidate Pipeline Developments

Voruciclib – Oral CDK9 inhibitor for the treatment of B-cell malignancies and acute myeloid leukemia

• Report clinical data from the ongoing Phase 1b trial evaluating voruciclib plus Venclexta® (venetoclax) in patients with acute myeloid leukemia around calendar year-end 2023.

ME-344 – Tumor selective mitochondrial inhibitor

• Initiate a Phase 1b clinical trial evaluating ME-344 plus Avastin® in relapsed colorectal cancer patients in the first half of calendar year 2023.

• Report clinical data from the Phase 1b clinical trial evaluating ME-344 plus Avastin in patients with relapsed colorectal cancer around calendar year-end 2023.

Third Quarter Fiscal Year 2023 Financial Results

• As of March 31, 2023, MEI had $112.0 million in cash, cash equivalents, and short-term investments with no outstanding debt.

• For the quarter ended March 31, 2023, cash used in operations was $12.1 million, compared to $17.0 million used in operations during the quarter ended March 31, 2022. The decrease in cash used in operations is due to a reduction in zandelisib costs as we continued the close down of development activities and other changes in working capital.

• Research and development expenses were $15.1 million for the quarter ended March 31, 2023, compared to $22.3 million for the quarter ended March 31, 2022. The decrease was primarily related to a reduction in zandelisib costs as we continued the close down of development activities in December 2022.

• General and administrative expenses were $7.2 million for the quarter ended March 31, 2023, compared to $8.9 million for the quarter ended March 31, 2022. The decrease primarily relates to personnel costs related to the reduction in workforce.

• MEI recognized revenue of $5.9 million for the quarter ended March 31, 2023, compared to $9.7 million for the quarter ended March 31, 2022. The decrease in revenue comes as a result of the discontinuation of the zandelisib program in December 2022 and the associated reduction in expense reimbursement under our global License, Development and Commercialization Agreement with Kyowa Kirin.

• Net loss was $15.4 million, or $2.32 per share, for the quarter ended March 31, 2023, compared to net loss of $8.7 million, or $1.31 per share for the quarter ended March 31, 2022. The Company had 6,662,857 shares of common stock outstanding as of March 31, 2023, compared with 6,657,602 shares as of March 31, 2022.

• The adjusted net income (a non-GAAP measure) for the quarter ended March 31, 2023, excluding non-cash expenses related to changes in the fair value of the warrants, was $15.4 million, compared to an adjusted net loss of $21.5 million for the quarter ended March 31, 2022.

Non-GAAP Financial Measures

To supplement our financial statements, which are prepared and presented in accordance with generally accepted accounting principles in the United States ("GAAP"), we provide investors with a non-GAAP financial measure, adjusted net income (loss), which we believe is helpful to our investors. We use adjusted net income (loss) for financial and operational decision-making purposes and as a means to evaluate period-to-period comparisons. We believe this non-GAAP financial measure provides useful information about our operating results, enhances the overall understanding of past financial performance and future prospects and allows for greater transparency with respect to metrics used by our management in its financial and operational decision-making.

The presentation of adjusted net income (loss) is not meant to be considered in isolation or as a substitute for net loss, the directly comparable financial measure prepared in accordance with GAAP. While we believe adjusted net income (loss) is an important tool for financial and operational decision-making and for evaluating our own operating results over different periods of time, we urge investors to review the reconciliation of this financial measures to the comparable GAAP financial measures included below, and not to rely on any single financial measure to evaluate our business.

We define adjusted net income (loss) as net income (loss), adjusted to exclude non-cash expenses related to changes in the fair value of the warrants. We have presented adjusted net income (loss) because we believe excluding the non-cash expenses related to changes in the fair value of warrants can produce a useful measure for period-to-period comparisons of our business.
