(Nasdaq: CRVS), a clinical-stage biopharmaceutical company, today announced that it has participated in a new $13.5 million financing for Angel Pharmaceuticals Ltd. (Angel Pharma), the Company’s collaboration partner in China. Corvus co-founded Angel Pharma in 2020 to enable the clinical development and commercialization of its pipeline in China as well as the development of other novel drugs. Corvus is Angel Pharma’s largest shareholder and is investing $5 million in the current financing. The funding is anticipated to support Angel Pharma’s ongoing Phase 1b/2 trial of soquelitinib for atopic dermatitis and a new Phase 2 trial of soquelitinib for asthma. Angel Pharma anticipates that it will report results from the initial cohort of the Phase 1b portion of the atopic dermatitis trial in late 2026 and will initiate the Phase 2 asthma trial in early 2027. “We believe Angel Pharma is making strong progress with the development of soquelitinib in China,” said Richard A. Miller, M.D., co-founder, president and chief executive officer of Corvus. “By continuing our investment in Angel Pharma, Corvus is positioned to benefit from soquelitinib clinical data generated by their trials and a significant ownership position that we believe has great potential for value creation as the opportunity for ITK inhibition in the large Chinese inflammation and immunology markets unfolds. Angel Pharma’s atopic dermatitis clinical trial is enrolling patients at several major dermatology centers in China and we anticipate that the findings from this trial will extend our experience with soquelitinib in this indication.” Angel Pharma is enrolling a Phase 1b/2 clinical trial evaluating soquelitinib in patients with moderate-to-severe atopic dermatitis. This is a blinded, placebo-controlled trial that is planned to evaluate a 12-week treatment regimen in 48 patients utilizing soquelitinib doses of 100 mg twice per day, 200 mg once per day, 200 mg twice per day and 400 mg once per day. The patient eligibility and endpoints are similar to those used previously by Corvus (including that patients may have received prior systemic therapies). Depending on the results from the Phase 1b portion of the study, an additional 60-90 patients are anticipated to be enrolled in the Phase 2 portion of the study. The trial is open at several leading dermatology centers in China who have been involved in global registration trials. The study is conducted in close collaboration with Corvus. About Corvus Pharmaceuticals Corvus Pharmaceuticals is a clinical-stage biopharmaceutical company pioneering the development of ITK inhibition as a new approach to immunotherapy for a broad range of immune diseases and cancer. The Company’s lead product candidate is soquelitinib, an investigational, oral, small molecule drug that selectively inhibits ITK. Soquelitinib is being evaluated in a registration Phase 3 clinical trial for relapsed/refractory PTCL and in a Phase 2 clinical trial for the treatment of atopic dermatitis. Its other clinical-stage candidates are being developed for a variety of cancer indications.

About Angel Pharmaceuticals Angel Pharmaceuticals is a privately held biopharmaceutical company developing a pipeline of precisely targeted investigational medicines for cancer, autoimmune, infectious and other serious diseases in China. Angel Pharma was launched through a collaboration with Corvus and investments from investors in China. Angel Pharma licensed the rights to develop and commercialize Corvus’ three clinical-stage candidates – soquelitinib, ciforadenant and mupadolimab – in greater China and obtained global rights to Corvus’ BTK inhibitor preclinical programs. Corvus has a 49% equity stake in Angel Pharma, excluding 6% of Angel Pharma’s equity reserved for issuance under the Angel Pharma employee stock ownership plan, and Corvus has designated three individuals on Angel Pharma’s five-person Board of Directors.

About Soquelitinib Soquelitinib (formerly CPI-818) is an investigational small molecule drug given orally designed to selectively inhibit ITK (interleukin-2-inducible T cell kinase), an enzyme that is expressed predominantly in T cells and plays a role in T cell and natural killer (NK) cell immune function. Soquelitinib has been shown to affect T cell differentiation and induce the generation of Th1 helper cells while blocking the development of both Th2 and Th17 cells and production of their secreted cytokines. Th1 T cells are required for immunity to tumors, viral infections and other infectious diseases. Th2 and Th17 helper T cells are involved in the pathogenesis of many autoimmune and allergic diseases. Recent studies have demonstrated that ITK controls a switch between the differentiation of Th17 proinflammatory cells and T regulatory suppressor cells. Inhibition of ITK leads to a shift toward T regulatory cell differentiation, which has the potential to suppress autoimmune and inflammatory reactions. The Company believes the inhibition of specific molecular targets in T cells may be of therapeutic benefit for patients with autoimmune and allergic diseases and in cancers, including solid tumors. Based on interim results from a Phase 1/1b clinical trial in patients with refractory T cell lymphomas, which demonstrated tumor responses in very advanced, refractory, difficult to treat T cell malignancies, the Company is enrolling a registration Phase 3 clinical trial (<a href="https://www.globenewswire.com/Tracker?data=f7-wSmbgXn0hD-iSENYImqg2Wq9r6pyEGKwXTs8VysRL2knFLYn_DWi_dUPrlNE6tVCiMozwFKbsvjWiINoeqpw7CCxbuiici4NfM2IhpOn65F-2O6q-G-UA3aOpGYkrYYTvA6Nk-k4BXFJDhb-jiQ==" rel="nofollow" target="_blank" title="NCT06561048">NCT06561048</a>) of soquelitinib in patients with relapsed/refractory PTCL. Soquelitinib is also now being investigated in a randomized placebo-controlled Phase 2 clinical trial in patients with atopic dermatitis. A publication describing the chemistry, enzymology and biology of soquelitinib appeared in npj Drug Discovery in December 2024 and is available online at the <a href="https://www.globenewswire.com/Tracker?data=lPV-5qUEiBQBv_fZ1zNKMP2rmE06kTThf-e4teIydQtpPKaB6fhHUIPMZMVuAXV6e2LTfI8VVtGcl65FxxveoLuD78N6XDUGHt6Efjy1OdIOiw-Efe-x2216zMsPRos5" rel="nofollow" target="_blank" title="Nature">Nature</a> website and on the <a href="https://www.globenewswire.com/Tracker?data=YjSpsUxAbzbGj-cWHvqS5EjEYGcqWKCXn_ahPPUj1cvSONg5YEY61m2OgoO7FpMiLmZjsAgWBfAcOJ033OSpy4X7-3CuZsVJYXjT__KOl_qJatAK5N2jYmFKt-ZjBEeg_y8ggDKDTK21Wk7-XDQXipe-hS4gZ4L6L8cxeGv3pGI=" rel="nofollow" target="_blank" title="Publications and Presentations">Publications and Presentations</a> page of the Corvus website. About Atopic Dermatitis Atopic dermatitis, also called eczema, is a chronic disease that can cause inflammation, redness, scaly patches, blisters and irritation of the skin. It affects up to 20% of children and up to 10% of adults, and treatments include topical therapies, oral therapies and systemic injectable biologic therapies. It is frequently associated with other allergic disorders such as food allergies and asthma. Atopic dermatitis, like asthma and allergy, involves the participation of Th2 lymphocytes which secrete cytokines that result in inflammation. Soquelitinib has been shown in preclinical studies to inhibit cytokine production from Th2 lymphocytes.
