Data highlights the differentiated mechanism of action of soquelitinib to enhance anti-tumor immune response to hematologic and solid tumors Soquelitinib shown to increase infiltration of cancer killing T cells with greater potency and less resistance due to exhaustion Corvus Pharmaceuticals, Inc. (Nasdaq: CRVS), a clinical-stage biopharmaceutical company, today announced the publication of preclinical data on soquelitinib (formerly known as CPI-818), the Company’s ITK inhibitor product candidate, which highlighted the selective inhibition of ITK to potentially enhance anti-tumor immune response to hematologic and solid tumors and provide a novel approach to cancer immunotherapy. The publication, entitled “Selective Inhibition of Interleukin 2 Inducible T Cell Kinase (ITK) Enhances Anti-Tumor Immunity in Association with Th1-skewing, Cytotoxic T cell Activation, and Reduced T Cell Exhaustion,” provides a detailed overview of the chemical structure, enzymatic activity and immunobiologic properties of soquelitinib. The published research was a result of collaborations between scientists at Corvus and researchers at the University of Michigan, The Ohio State University, Peking University and Stanford University. The publication is now available online as a preprint at bioRxiv.org and on the Publications and Presentations page of the Corvus website. “This significant scientific report demonstrates the potential of highly selective ITK inhibition, now enabled by soquelitinib. The data indicate that that this mechanism, if approved, may become the backbone of a new immunotherapy approach to cancer and we believe it will extend the opportunity for the continued development of soquelitinib as a single agent or in combination with other therapies to treat a variety of cancer tumor types,” said Richard A. Miller., co-founder, president and chief executive officer of Corvus. The findings reported indicate that ITK is a novel drug target and its blockade may enhance the body’s immune response to cancer. ITK is an enzyme predominantly expressed by T lymphocytes. ITK plays a major role in the function of T cells which are generally acknowledged as a critical cell in the immunotherapy of cancer. Soquelitinib is currently being studied in a Phase 1/1b clinical trial as a single agent therapy in patients with relapsed T cell lymphoma (TCL). Corvus plans to meet with the FDA in the third quarter of 2023 to discuss a Phase 3 registration clinical trial in patients with relapsed TCL. Key results from the preclinical studies described in the publication demonstrated that soquelitinib: Is a covalent, irreversible inhibitor that selectively binds to and inhibits ITK function while sparing other closely related kinases, including resting lymphocyte kinase (RLK). Inhibited Th2 T cell function and the production of various Th2 cytokines leading to Th1 skewing and production of interferon gamma and tumor necrosis factor, which are important cytokines in tumor rejection. Th2 cytokines have been previously implicated in promoting tumor growth and are also involved in autoimmune and allergic diseases. Activated cytotoxic killer cells and increases infiltration of these cells into tumors. Reduced and reversed T cell exhaustion resulting in a more potent and prolonged immune response. T cell exhaustion is often a major reason for resistance to immune checkpoint therapy. Led to in vivo anti-tumor activity in several mouse tumor models, including colon, renal, melanoma, B cell and T cell tumors. 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 cancer and immune diseases. The Company’s lead product candidate is soquelitinib, an investigational, oral, small molecule drug that selectively inhibits ITK and is in a mid-stage clinical trial for patients with T cell lymphoma. Its other clinical-stage candidates are being developed for a variety of cancer indications. For more information, visit www.corvuspharma.com. About Soquelitinib (CPI-818) Soquelitinib is an investigational small molecule drug given orally that has selectively inhibited ITK (interleukin-2-inducible T cell kinase) in preclinical studies. ITK, an enzyme, is expressed predominantly in T cells and plays a role in T cell and natural killer (NK) cell immune function. The immunologic effects of soquelitinib lead to what is known as Th1 skewing and is made possible by the high selectivity of soquelitinib for ITK. Recent clinical data in T cell lymphomas, and preclinical studies in murine solid tumor models, suggests that soquelitinib has the potential to control differentiation of normal T helper cells and enhance immune responses to tumors by augmenting the generation of cytotoxic killer T cells and the production of cytokines that inhibit cancer cell survival. Optimal doses of soquelitinib have 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 Th2 related 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. The Company believes the inhibition of specific molecular targets in T cells may be of therapeutic benefit for patients with cancers, including solid tumors, and in patients with autoimmune and allergic diseases. The Company is conducting a Phase 1/1b trial in patients with refractory T cell lymphomas that was designed to select the optimal dose of soquelitinib and evaluate its safety, PK, target occupancy, immunologic effects, biomarkers and efficacy. Interim data from the Phase 1/1b clinical trial of soquelitinib for T cell lymphoma demonstrated tumor responses in very advanced, refractory, difficult to treat T cell malignancies, and identified a dose that maximally drives Th1 skewing.

Positive Preliminary Topline Data for ATI-450, an Investigational Oral MK2 Inhibitor, in Moderate to Severe Rheumatoid Arthritis Announced in January 2021 ATI-450 Data Support New Oral Approach for the Potential Treatment of Immuno-inflammatory Diseases, such as Rheumatoid Arthritis Public Offering of $103.5M in January 2021 Strengthens Balance Sheet WAYNE, Pa., Feb. 25, 2021 (GLOBE NEWSWIRE) -- Aclaris Therapeutics, Inc. (NASDAQ: ACRS), a clinical-stage biopharmaceutical company focused on developing novel drug candidates for immuno-inflammatory diseases, today announced its financial results for the fourth quarter and full year of 2020 and provided a corporate update. “As we reflect on 2020, we are proud of how we have progressed our immuno-inflammatory development programs,” said Dr. Neal Walker, President & CEO of Aclaris. “We are very excited about the platform potential of ATI-450, an oral MK2 inhibitor which we have shown to inhibit TNFα, IL1β, and IL6. Given its novel mechanism, there are several immuno-inflammatory indications that ATI-450 may potentially address. We are also excited about the potential of our pipeline which is internally generated from KINect®, our proprietary drug discovery platform, for various immuno-inflammatory indications. We look forward to building on this momentum in 2021.” Research and Development Highlights: The global COVID-19 pandemic continues to rapidly evolve and has caused and may continue to cause Aclaris to experience disruptions that could impact the timing of its research and development and regulatory activities listed below. ATI-450 , an investigational oral small molecule MK2 inhibitor compound: ATI-450-RA-201 : A Phase 2a, multicenter, randomized, investigator and patient-blind, sponsor-unblinded, parallel group, placebo-controlled clinical trial to investigate the safety, tolerability, pharmacokinetics and pharmacodynamics of ATI-450 in subjects with moderate to severe rheumatoid arthritis. Positive preliminary topline data announced in January 2021. In this trial, ATI-450 demonstrated durable clinical activity, as defined by a marked and sustained reduction in DAS28-CRP and improvement of ACR20/50/70 responses over 12 weeks. This clinical activity was further supported by pharmacodynamic analyses showing a marked and durable inhibition of TNFα, IL1β, IL6, and IL8 in ex vivo stimulated samples as well as an endogenous inflammation biomarker analysis which also demonstrated a marked and sustained inhibition of median concentrations of hsCRP, TNFα, IL6, IL8, and MIP1β in the treatment arm over the 12 week period. ATI-450 was generally well tolerated. The most common adverse events (AE) (each reported in 2 subjects) were urinary tract infection (UTI), elevated lipids and ventricular extrasystoles, all of which were determined to be unrelated to treatment except for one UTI. There was one non-treatment-related serious adverse event (COVID-19) reported in the four-week safety follow-up phase of the trial in a subject who was no longer receiving treatment. Aclaris intends to progress ATI-450 into a Phase 2b trial in moderate to severe rheumatoid arthritis in the second half of 2021. Aclaris is currently evaluating additional potential indications driven by TNFα, IL1β and IL6 as part of its planned expansion of its Phase 2 immuno-inflammatory clinical development programs. ATI-450-PKPD-102 : A Phase 1, placebo-controlled, randomized, observer-blind clinical trial to investigate the safety, tolerability, pharmacokinetics, and pharmacodynamics of ATI-450 at 80 mg and 120mg twice daily in health subjects. Positive preliminary topline data announced in January 2021. Pharmacodynamic analysis demonstrated incremental cytokine suppression at these higher doses. ATI-450 was generally well tolerated. The most common AEs (reported by 2 or more subjects who received ATI-450) were headache, dizziness, nausea, parasthesia and, in the post-dosing safety follow-up phase of the trial, dry skin. These AEs were all mild in severity. A final analysis of this trial is underway. ATI-450-CAPS-201 : A Phase 2a, multicenter, open-label, single-arm clinical trial to investigate the safety, tolerability, efficacy and pharmacodynamics of ATI-450 for the maintenance of remission in subjects with cryopyrin-associated periodic syndrome (CAPS) previously managed with anti-IL1 therapy. Due to the COVID-19 pandemic, subject enrollment in this trial was paused. As a result of the ongoing pandemic and given the positive preliminary topline data from the ATI-450-RA-201 trial, Aclaris has decided to focus its efforts and resources on other immuno-inflammatory diseases. , an investigational oral small molecule MK2 inhibitor compound: ATI-1777 , an investigational topical “soft” Janus Kinase (JAK) 1/3 inhibitor compound: ATI-1777-AD-201 : An ongoing Phase 2a, multicenter, randomized, double-blind, vehicle-controlled, parallel-group clinical trial to investigate the efficacy, safety, tolerability and pharmacokinetics of ATI-1777 in subjects with moderate to severe atopic dermatitis. The primary endpoint is the percentage change from baseline in the Eczema Area and Severity Index (EASI) score at week 4. Data from this trial are expected mid-year 2021. , an investigational topical “soft” Janus Kinase (JAK) 1/3 inhibitor compound: ATI-2138 , an investigational oral ITK/TXK/JAK3 (ITJ) inhibitor compound: Aclaris is developing ATI-2138 as a potential treatment for T-cell mediated diseases such as psoriasis and/or inflammatory bowel disease and expects to submit an Investigational New Drug Application for ATI-2138 in the second half of 2021. , an investigational oral ITK/TXK/JAK3 (ITJ) inhibitor compound: Financial Highlights: Liquidity and Capital Resources As of December 31, 2020, Aclaris had aggregate cash, cash equivalents, restricted cash and marketable securities of $54.1 million compared to $75.0 million as of December 31, 2019.
