IMG-007

Treatment with IMG-007, the only clinical-stage nondepleting anti-OX40 monoclonal antibody (mAb), led to rapid, marked, and durable improvement of skin signs in patients with atopic dermatitis (AD). Overall, IMG-007 was well-tolerated, without any reports of pyrexia or chills. IMG-007 is also being evaluated for the treatment of alopecia areata (AA). Final results are anticipated in Q3 2024. May 06, 2024 -- Inmagene Biopharmaceuticals ("Inmagene" or the “Company”), a clinical-stage biotechnology company developing innovative and differentiated therapies for immunological and inflammatory (I&I) diseases, today announced positive interim data from Phase 2a trial of IMG-007 in patients with AD. IMG-007 is a nondepleting anti-OX40 mAb, bioengineered to have a silenced antibody-dependent cellular cytotoxicity (ADCC) function and a prolonged half-life. In a prior Phase 1 single-dose study in healthy adults, IMG-007 demonstrated a favorable safety and tolerability profile, with no reports of pyrexia or chills, which is consistent with the abolished ADCC function. Furthermore, IMG-007 showed a slow antibody clearance and a 31-day half-life at anticipated therapeutic dose levels, which could enable it to be dosed every 12 weeks (Q12W) for induction therapy, and even less frequently for maintenance therapy in AD treatment. The Phase 2a trial (NCT05984784) evaluates the safety, pharmacokinetics, and efficacy of IMG-007 in adult patients with moderate-to-severe AD who had inadequate response to and/or intolerant of topical therapies. Patients who had received prior systemic agents, such as biologics, were also included in the trial. Topical or systemic AD medications were not permitted during the study. Eligible patients were to receive three intravenous infusions of 300 mg IMG-007 over 4 weeks (Baseline, Week 2 and 4) and to be followed up for up to 24 weeks. Key study endpoints include safety and percent change from baseline in eczema area and severity index (EASI) over time. A total of 13 patients were enrolled from 6 centers in the U.S. and Canada. Baseline key disease characteristics included mean EASI of 29.5, mean body surface area (BSA) of 52.0%, and 61.5% patients with investigator’s global assessment (IGA=3) and 38.5% with IGA=4. IMG-007 treatment resulted in a rapid and marked improvement from baseline in EASI score as early as Week 1 and continued improvement over time after the last dose of IMG-007 at Week 4. The mean percent improvement from baseline in EASI was 23%, 29%, 47%, 66%, 68%,77%, and 87% at Weeks 1, 2, 4, 8, 12, 16, and 20, respectively. By Week 20, a total of 69%, 54%, and 31% of patients achieved EASI improvement of at least 50% (EASI-50), at least 75% (EASI-75), and at least 90% (EASI-90), respectively. There were no serious adverse events (SAEs), and no adverse events (AEs) leading to treatment discontinuation, and no treatment-related AEs. There were no reports of pyrexia or chills. “Inhibiting OX40-OX40L signaling is an exciting potential therapeutic approach to treating AD,” said Jonathan Silverberg, M.D., Ph.D., Professor of Dermatology at The George Washington University School of Medicine and Health Sciences. “By uniquely targeting the OX40 receptor without depleting T cells and with its long half-life, IMG-007 presents a best-in-class potential to not only minimize safety risks associated with T cell depletion, but also provide patients with a more convenient dosing regimen such as Q12W.” “We are highly encouraged by the remarkable efficacy seen with a short 4-week treatment period. Future studies of continuous treatment with IMG-007 in patients with AD could potentially drive more robust efficacy than seen in this proof-of-concept study,” said Yufang Lu, M.D., Ph.D., Chief Medical Officer of Inmagene. “Given the important role of the OX40-OX40L axis in the pathogenesis of a spectrum of I&I diseases, IMG-007 could be suitable for a number of indications. We are working hard to accelerate the clinical development of IMG-007 in AD with our subcutaneous formulation.” In addition to the Phase 2a trial in patients with AD for which final results are anticipated in Q3 2024, IMG-007 is also being evaluated in a global study in adult patients with AA with anticipated initial data readout in Q4 2024. Inmagene is a global clinical-stage biotechnology company developing novel therapeutics for immunological and inflammatory (I&I) diseases. The company’s highly differentiated clinical-stage pipeline has multiple candidates with best-in-class potential. The lead asset IMG-007, a nondepleting anti-OX40 mAb, is in two global Phase 2a clinical trials in atopic dermatitis and alopecia areata (AA). IMG-004, a non-covalent reversible BTK inhibitor with an extended half-life and pharmacodynamic effect, enabling its potential for once-daily dosing, is completing a Phase 1 multiple-dose study. IMG-008, a long-acting anti-IL-36R mAb is entering global Phase 1 clinical development. IMG-007 is a humanized anti-OX40 IgG1 mAb, with a silenced ADCC function and an extended half-life. The OX40-OX40L axis is important in T cell activation, expansion, and survival, thereby having an important role in the pathogenesis of a spectrum of I&I diseases. In nonclinical studies, IMG-007 potently blocked the signaling between OX40 and OX40L. Phase 1 single dose study demonstrated a 31-day half-life at anticipated therapeutic dose levels, enabling the potential for once every 12 weeks (Q12W) dosing for induction therapy and even less frequently for maintenance therapy, and a favorable safety profile, without any reports of pyrexia or chills. IMG-007 is being evaluated for the treatment of moderate-to-severe atopic dermatitis and alopecia areata in two Phase 2a studies.

Net income attributable to HUTCHMED of $100.8 million.2024 Oncology/Immunology consolidated revenue guidance of $300 million to $400 million, driven by 30% to 50% growth target in marketed product sales and royalties.R&D expenses focused in line with strategy targeting key projects.Strengthened cash balance, with $886.3 million at year end (2022: $631.0m), ensures HUTCHMED is well placed to deliver on its objective of becoming a self-sustaining business. 2023 FULL YEAR RESULTS & BUSINESS UPDATES Mr Simon To, Executive Chairman of HUTCHMED, said, “We have made significant progress throughout 2023. We executed against our commitment to bring our innovative medicines to patients worldwide with the U.S. FDA approval of FRUZAQLA™ in November 2023, while remaining dedicated to becoming a self-sustaining business. The Takeda partnership, which is one of the biggest small-molecule overseas licensing deals in the history of China biotech, strengthened our cash position by $435 million. Takeda delivered a successful U.S. launch within 48 hours of approval, and has subsequently seen strong early patient uptake.” “We will continue to deliver on our strategy in 2024. We will stay focused on our target of becoming sustainable through our balanced strategy of growing sales of our novel medicines in China, and advancing our medicines overseas with our partners. This, when combined with our other goals on pipeline progression and further business development, means that while the global macroeconomic environment remains uncertain, HUTCHMED is positioned to thrive and continue to deliver innovative medicines to ever more patients around the world.” Dr Weiguo Su, Chief Executive Officer and Chief Scientific Officer of HUTCHMED, said, “HUTCHMED delivered impressive financial results in 2023, with revenue up 97% to $838 million. This, alongside our significantly strengthened cash balance of $886 million, will enable us to continue advancing our pipeline and successfully executing our strategy.” “2023 was an important year for HUTCHMED, particularly for fruquintinib, for which we filed market authorization applications in the U.S., EU and Japan, based on the successful FRESCO-2 study. Following the U.S. FDA approval for third-line patients with advanced CRC, we continue to work together with Takeda to pursue additional launches in new markets worldwide. In China, we also filed an NDA for second-line gastric cancer based on the FRUTIGA study.” “Another milestone was the successful ESLIM-01 registration study in China in ITP patients for sovleplenib, our first potential novel medicine in immunological diseases. The NDA was accepted and granted priority review by the NMPA in January 2024. There are over 250,000 new and existing adult ITP patients in China20. The treatment options are limited to steroids and TPO/TPO-RAs21, representing an unmet medical need that sovleplenib could help address, with its new mechanism of action and favorable safety profile. Syk inhibition has the potential to target other major diseases such as rheumatoid arthritis. We are also planning to initiate clinical development of sovleplenib outside China in 2024.” “For savolitinib, we completed the confirmatory trial in NSCLC patients with MET22 exon 14 skipping alterations. An NDA submission is expected in the first quarter of 2024, with potential to expand the label indication to include first-line patients in China. Outside China, we will continue our work with AstraZeneca on the pivotal global savolitinib lung cancer trial SAVANNAH, which, subject to favorable data, can support a filing to the U.S. FDA for approval. This study completed enrollment with a potential NDA submission towards the end of 2024 in EGFR23 mutant NSCLC patients who progressed on TAGRISSO® treatment, which received U.S. FDA Fast Track designation in January 2023. We believe the convenient dosing, targeted efficacy and safety profile of savolitinib as an oral medicine in combination with TAGRISSO®, the leading oral third-generation EGFR TKI24, should position it well in a competitive market and address the unmet needs of MET+ NSCLC patients.” "Our China commercialization efforts progressed well, as we successfully renewed NRDL25 coverage for both fruquintinib and surufatinib without further price reduction. Their in-market sales saw strong growth in 2023. Over the next two years, we plan to continue growth in China through expanded indications and the launch of new products together with revenue from FRUZAQLA™ overseas commercialization.” I. COMMERCIAL OPERATIONS Total revenue increased 97% (102% at CER) to $838.0 million in 2023 (2022: $426.4m), driven by the Takeda partnership, our strong commercial progress in China, and growth in third-party distribution sales, resulting in a net income of $101 million for 2023.

IMPACT OF COVID-19 While restrictive measures related to COVID-19 were gradually lifted in China starting from December 2022, COVꞮD-19 had some impact on our research, clinical studies and our commercial activities in the first few months of 2023. Measures were put in place to reduce the impact and, in the second quarter of 2023, these activities normalized. FINANCIAL HIGHLIGHTS Foreign exchange impact: The RMB depreciated against the U.S. dollar on average by approximately 5% during 2023, which has impacted our consolidated financial results as highlighted below. Cash, Cash Equivalents and Short-Term Investments were $886.3 million as of December 31, 2023 compared to $631.0 million as of December 31, 2022.

Full year 2024 guidance for Oncology/Immunology consolidated revenue is $300 million to $400 million, driven by 30% to 50% growth target in oncology marketed product revenue. HUTCHMED’s work in 2024 and beyond will be supported by its strong balance sheet, which grew by $255 million to $886 million in Cash, Cash Equivalents and Short-Term Investments as of December 31, 2023.
