SHANGHAI, Aug. 24, 2022 /PRNewswire/ -- Everest Medicines (HKEX 1952.HK, "Everest", or the "Company"), a biopharmaceutical company focused on developing and commercializing transformative pharmaceutical products to address critical unmet needs in Asia Pacific markets, today announced its interim results for first half of 2022 along with a corporate progress update.

Everest has made significant progress on all fronts of our business and therapeutic areas in the first half of 2022 as the company continued to progress clinical and regulatory development across our diverse pipeline, build up self-discovery capabilities and expand key partnerships. Looking ahead, by strengthening our capital structure through the recent strategic sale of the rights to Trodelvy in Asia territories, Everest has the capacity to accelerate the development of important assets in our portfolio with first-in-class or best-in-class potential, further advance our internal discovery efforts and pursue business development opportunities that will maximize impact for patients worldwide and create sustained, long-term value for our shareholders. Below are product highlights in 1H and anticipated future milestones:

NEFECON (Tarpeyo^TM), a novel oral formulation of budesonide (budesonide delayed release capsules) in the development for the treatment of primary immunoglobulin A nephropathy (IgAN).

- Product development achievements during the Reporting Period:

• In March 2022, the Company announced it entered into a license agreement with Calliditas to develop and commercialize NEFECON for the treatment of primary IgAN in South Korea, expanding its license in addition to rights held in Greater China and Singapore. The deal signaled the Company's latest efforts to further enhance its international commercial footprint.
• In April 2022, the Company announced the findings of reduction in proteinuria and stabilization of eGFR in a Chinese subpopulation after nine months of treatment with NEFECON are in line with topline results from Part A of the pivotal global Phase 3 clinical trial NefIgArd, which were reported in November 2020 by our partner, Calliditas Therapeutics.

- Post-Reporting Period achievements and expected milestones:

• In July 2022, our partner Calliditas was granted conditional marketing authorization for Kinpeygo^® (developed under the name NEFECON) by the European Commission for the treatment of IgAN in adults at risk of rapid disease progression with a urine protein-to-creatinine ratio (UPCR) ≥ 1.5 g/gram.
• We expect to file a New Drug Application (NDA) for NEFECON in China in the second half of 2022.

Etrasimod, a once-daily, oral, selective sphingosine 1-phosphate (S1P) receptor modulator for the treatment of moderately-to-severely active ulcerative colitis (UC).

- Product development achievements during the Reporting Period:

• In May 2022, our licensing partner, Pfizer Inc., presented detailed results from two pivotal studies that make up the ELEVATE UC Phase 3 registrational program evaluating etrasimod for the treatment of moderately-to-severely active UC. Both Phase 3, multi-center, randomized, placebo-controlled trials achieved all primary and key secondary endpoints, with etrasimod demonstrating a safety profile consistent with previous studies. In the 52-week ELEVATE UC 52 study, clinical remission was 27.0% for patients receiving etrasimod compared to 7.4% for patients receiving placebo at week 12 (19.8% differential, P=<.001) and was 32.1% compared with 6.7% at week 52 (25.4% differential, P=<.001). In the 12-week ELEVATE UC 12 study, clinical remission was achieved among 24.8% of patients receiving etrasimod compared with 15.2% of patients receiving placebo (9.7% differential, P=.0264). The data from ELEVATE UC 52 & UC 12 are expected to form the basis for planned future regulatory filings, which Pfizer expects to initiate later this year.

- Post-Reporting Period achievements and expected milestones:

• We are conducting a Phase 3 study for etrasimod for the treatment of moderate-severe UC, which is expected to complete enrollment in 2023.
