(NASDAQ: KYMR), a clinical-stage biopharmaceutical company advancing a new class of oral small molecule degrader medicines for immunological diseases, today reported financial results for the second quarter ended June 30, 2025, and provided business highlights and updates on its pipeline. “The first half of this year has been rich in data and milestones that build upon our scientific achievements and further validate the potential impact of our industry leading oral immunology pipeline. This includes the exceptional data from the healthy volunteer trial for KT-621, our once-a-day oral STAT6 degrader, which exceeded expectations across every measure showing robust target and pathway engagement, as well as safety undifferentiated from placebo,” said Nello Mainolfi, PhD, Founder, President and CEO, Kymera Therapeutics. “We’re continuing to rapidly advance this program, and with the enrollment progress we have made in the KT-621 BroADen Phase 1b trial in AD patients, we’re on track to share the BroADen study data, and to initiate our first Phase 2b study in AD, both in the fourth quarter.” Dr. Mainolfi continued, “Additionally, we’re advancing KT-579, our oral IRF5 degrader program with broad clinical promise in areas of high unmet need, on the path to clinical entry early next year. We recently announced two collaboration updates as well, including an exciting new partnership with Gilead focused on our innovative CDK2 molecular glue program, and Sanofi’s plans to advance our second generation IRAK4 degrader, KT-485, into clinical studies. With $1 billion in cash and an extended cash runway into the second half of 2028, we are well-positioned to deliver on our goals and improve patients’ lives with a new class of oral medicines with biologics-like profiles.” Business Highlights, Recent Developments and Upcoming Milestones STAT6 Degrader Program KT-621 is an investigational, first-in-class, once daily, oral degrader of STAT6, the specific transcription factor responsible for IL-4/IL-13 signaling and the central driver of Th2 inflammation. In the Phase 1 clinical study in healthy volunteers, KT-621 demonstrated complete STAT6 degradation in blood and skin following low daily oral doses, reductions of multiple disease relevant Th2 biomarkers, and a safety profile undifferentiated from placebo. KT-621, the first STAT6-directed medicine to enter clinical evaluation, has the potential to transform treatment paradigms for more than 130 million patients around the world, including children and adults, suffering from Th2 diseases such as AD, asthma, chronic obstructive pulmonary disease (COPD), chronic rhinosinusitis with nasal polyps (CRSwNP), eosinophilic esophagitis (EoE), chronic spontaneous urticaria (CSU), and prurigo nodularis (PN), among others. In June, the Company announced positive results from its Phase 1 healthy volunteer trial, surpassing Kymera’s target product profile and validating KT-621’s oral, dupilumab-like profile. The trial evaluated the safety, tolerability, pharmacokinetics and pharmacodynamics of single- (SAD) and multiple-ascending (MAD) doses of KT-621 compared to placebo. KT-621 demonstrated rapid, deep and prolonged STAT6 degradation in blood and skin. In blood, >90% mean STAT6 degradation was achieved at all doses above 1.5 mg. Complete STAT6 degradation was achieved in both blood and skin at all MAD doses ≥50 mg. KT-621 demonstrated an impact on Th2 biomarkers in line or superior to dupilumab with median TARC reduction up to 37% and median Eotaxin-3 reduction up to 63%. KT-621 was well-tolerated with a safety profile undifferentiated from placebo.The Company completed a healthy volunteer clinical trial in Japanese subjects to provide the pharmacokinetic and safety data required by regulators prior to enrollment of patients in Japan in the planned global Phase 2b studies. Results from the Japanese study were consistent with the Phase 1 healthy volunteer data reported in the U.S. trial, including robust degradation and favorable safety, and will be shared at a future medical meeting.The KT-621 BroADen Phase 1b trial, an open label study in patients with moderate to severe AD, is ongoing, with data expected to be reported in the fourth quarter of 2025. This single arm study is evaluating two doses with the objective to show that robust STAT6 degradation in blood and skin by KT-621 has a dupilumab-like effect on reducing multiple Th2 biomarkers in the blood and on the transcriptome of active AD skin lesions at four weeks. The study will also assess effects on clinical endpoints such as Eczema Area and Severity Index (EASI) and pruritus numerical rating scale (NRS).The Company completed four-month GLP toxicology studies evaluating KT-621 in NHP and rat and, consistent with its earlier two-week non-GLP and four-week GLP toxicology studies, did not observe any adverse events of any type at all doses and concentrations tested.Two parallel Phase 2b studies in AD and asthma patients are planned to begin in the fourth quarter of 2025 and the first quarter of 2026, respectively. Doses have been selected for the Phase 2b studies in moderate to severe AD and asthma patients, which are expected to accelerate KT-621 development and enable dose selection for subsequent parallel Phase 3 registration studies across multiple Th2 dermatology, gastroenterology and respiratory indications.Kymera has selected a follow-on oral STAT6 degrader to KT-621, with a strong potency, selectivity, and safety profile, and has advanced it through all required IND-enabling studies. The degrader is IND-ready should the Company decide to further advance it into the clinic in the future.In May, the Company presented additional KT-621 preclinical data at the American Thoracic Society (ATS) Annual Meeting and was featured in an oral showcase presentation as part of the ATS Respiratory Innovation Summit. The new asthma efficacy mouse model data demonstrated both prevention of disease progression as well as reversal of established disease, building upon the compelling preclinical characterization of KT-621.The Company will present the KT-621 Phase 1 healthy volunteer data in a late-breaking oral presentation at the European Respiratory Society (ERS) Congress being held September 27-October 1, 2025, in Amsterdam, Netherlands. Additionally, the Company will present KT-621 preclinical data in a poster at the European Academy of Dermatology and Venereology (EADV) Congress being held September 17-20, 2025, in Paris, France. IRF5 Degrader Program KT-579 is an investigational, first-in-class, oral degrader of IRF5, a genetically validated transcription factor and master regulator of immunity. KT-579 has the potential to selectively block inflammation and restore immune regulation by inhibiting pro-inflammatory cytokines, Type I IFN, and autoantibody production while sparing normal cell function. In preclinical studies, KT-579 degraded IRF5 across multiple preclinical species and in all disease-relevant tissues. In preclinical models of lupus and rheumatoid arthritis (RA), KT-579 was equal or more efficacious than clinically active or marketed small molecule inhibitors and biologics. In preclinical safety studies, KT-579 did not show any adverse effects of any type at doses and concentrations tested. KT-579 has the potential to be the first novel mechanism with broad utility in diseases where effective and well tolerated oral therapies are needed, such as lupus, Sjögren's, inflammatory bowel disease (IBD), RA and others. KT-579 IND-enabling studies are ongoing. The Company intends to advance the program into Phase 1 testing in early 2026.Additional new data from preclinical animal models in lupus and RA will be shared in two posters at the American College of Rheumatology (ACR) Annual Meeting being held October 24-29, 2025, in Chicago, Illinois. Collaboration Updates In June, the Company entered into an exclusive option and license agreement with Gilead to accelerate the development and commercialization of a novel molecular glue degrader program targeting CDK2 with broad oncology treatment potential. Under the terms of the agreement, Kymera is eligible to receive up to $750 million in total payments, including up to $85 million in upfront and potential option exercise payments. In addition, Kymera may also receive tiered royalties ranging from high single-digit to mid-teens on net product sales under the collaboration. Kymera will lead all research activities for the CDK2 program. If Gilead exercises its option to exclusively license the program, Gilead will have global rights to develop, manufacture and commercialize all products resulting from the collaboration.In June, Sanofi informed Kymera that KT-485 (SAR447971), a selective, potent, oral IRAK4 degrader, has been prioritized for development under the companies’ existing IRAK4 collaboration, and is expected to advance into Phase 1 testing next year. Based on this decision, Sanofi will not advance Kymera’s first-generation IRAK4 degrader, KT-474. Additionally, Sanofi communicated its decision to exercise its participation election right for the IRAK4 target under the terms of the companies’ collaboration agreement. Kymera achieved a $20 million milestone in the second quarter of 2025 related to preclinical activities associated with KT-485 and is eligible to receive an additional milestone upon the start of Phase 1 clinical testing, part of up to $975 million of potential clinical, regulatory and commercial milestones. Corporate Updates In June, the Company completed a $250 million underwritten equity offering. Total gross proceeds, including the underwriters’ subsequent full exercise of the overallotment option, were approximately $288 million. With these proceeds, and the upfront payment from Gilead received in July, the Company ended the month of July 2025 with an unaudited cash balance of approximately $1 billion and has extended its cash runway into the second half of 2028. Financial Results Collaboration Revenues: Collaboration revenues were $11.5 million for the second quarter of 2025 compared to $25.7 million for the second quarter of 2024. Collaboration revenues were all attributable to the Company’s Sanofi collaboration and the second quarter of 2025 included recognition of all remaining deferred revenue related to the collaboration. The upfront payment from Gilead has initially been recorded as deferred revenue and is expected to be recognized as revenue over the research term. Research and Development Expenses: Research and development expenses were $78.4 million for the second quarter of 2025 compared to $59.2 million for the second quarter of 2024. This increase was primarily due to increased expenses related to the investment in the Company’s STAT6 program, platform and discovery programs, as well as costs related to continued growth in the research and development organization. Stock based compensation expenses included in R&D were $8.0 million and $7.3 million for the second quarters of 2025 and 2024, respectively. General and Administrative Expenses: General and administrative expenses were $17.6 million for the second quarter of 2025 compared to $17.4 million for the second quarter of 2024. The increase was primarily due to an increase in legal and professional service fees in support of the Company’s growth and an increase in personnel, facility, and other expenses to support growth as a public company. Stock based compensation expenses included in G&A were $7.4 million and $7.1 million for the second quarters of 2025 and 2024, respectively. Net Loss: Net loss was $76.6 million for the second quarter of 2025 compared to $42.1 million for the second quarter of 2024. Cash and Cash Equivalents: As of June 30, 2025, Kymera had $963.1 million in cash, cash equivalents and investments. As of July 31, 2025, Kymera had approximately $1 billion in cash, cash equivalents and investments, inclusive of the net proceeds from the full exercise of the underwriters’ option in our June 2025 follow-on offering and the upfront payment from the Gilead collaboration, both of which were received in July. Kymera expects that its cash and cash equivalents will provide the Company with a cash runway into the second half of 2028, beyond multiple clinical inflection points in our pipeline.
