Kymera Therapeutics Announces Second Quarter 2021 Financial Results and Provides a Business Update


Positive interim results from Single Ascending Dose portion of Phase 1 trial of first-in-class oral IRAK4 degrader KT-474 demonstrated degrader proof-of-mechanism


Recently initiated dosing of healthy volunteers in the Multiple Ascending Dose portion of Phase 1 trial of KT-474


Expect Investigational New Drug Applications for oncology degrader programs KT-413 and KT-333 in 2H 2021


Strong financial position after successful follow-on offering with pro forma cash position of $647 million to support continued company, pipeline, and platform expansion


Watertown, Mass. (August 6, 2021) – Kymera Therapeutics, Inc. (NASDAQ: KYMR), a clinical-stage biopharmaceutical company advancing targeted protein degradation to deliver novel small molecule protein degrader medicines, today reported business highlights and financial results for the second quarter ended June 30, 2021.


“We recently reported positive interim results from our Phase 1 trial of KT-474 that demonstrated degrader proof-of-mechanism for the first time in a placebo-controlled, randomized study, which we believe greatly de-risks its development as a potentially best-in-class anti-inflammatory oral agent and provides a key clinical proof-of-concept for Kymera’s platform. We have recently begun evaluating repeat dosing of KT-474 in healthy volunteers, and we look forward to presenting updated data establishing human proof-of-biology later this year,” said Nello Mainolfi, PhD, Co-Founder, President and CEO of Kymera Therapeutics. “We expect the second half of 2021 to be eventful with key milestones across our lead programs, including expected IND filings for our two lead oncology programs. Further, our recent successful financing further enables us to deliver on our vision of building a fully integrated, best-in-class degrader medicines company.”


Program Updates and Milestones

Kymera is discovering and developing novel small molecule therapeutics designed to selectively degrade disease-causing proteins by harnessing the body’s own natural protein degradation system, with an initial focus on immune-inflammatory diseases and oncology.


IRAK4 Degrader Program

IRAK4 is a key protein involved in inflammation mediated by the activation of toll-like receptors (TLRs) and IL-1 receptors (IL-1Rs). Aberrant activation of these pathways is the underlying cause of multiple immune-inflammatory conditions. KT-474, a potential first-in-class, orally bioavailable IRAK4 degrader, is being developed for the treatment of TLR/IL-1R-driven immune-inflammatory diseases with high unmet medical need, such as atopic dermatitis, hidradenitis suppurativa, rheumatoid arthritis, and potentially others. KT-474 is designed to block TLR/IL-1R-mediated inflammation more broadly compared to monoclonal antibodies targeting single cytokines, and to enable pathway inhibition that is superior to IRAK4 kinase inhibitors by abolishing both the kinase and scaffolding functions of IRAK4. Kymera is collaborating with Sanofi on the development of degrader candidates targeting IRAK4, including KT-474 (SAR444656), outside of the oncology and immuno-oncology fields.







Recent Updates:


In May 2021, Kymera presented preclinical data demonstrating KT-474’s superiority compared to a clinically active small molecule IRAK4 kinase inhibitor across a wide variety of immune-inflammatory preclinical in vivo models. The late-breaking data were presented at the American Association of Immunologists’ Virtual IMMUNOLOGY2021™ annual meeting.


In June 2021, Kymera announced positive interim results from the Single Ascending Dose (SAD) portion of the Phase 1 clinical trial of KT-474, demonstrating the first degrader proof-of-mechanism in targeted protein degradation in a randomized, placebo-controlled healthy volunteer study. KT-474 achieved and exceeded the Phase 1 degradation goal of 85%, with maximal degradation of 94%, within the SAD portion of the Phase 1 trial dosed to date, with profound IRAK4 degradation after a single oral dose that lasted for at least six days at all dose levels (25, 75, 150 and 300 mg), with no treatment-related adverse events observed. Additionally, the partial clinical hold on the Multiple Ascending Dose (MAD) portion of the Phase 1 trial of KT-474 was lifted following review by the U.S. Food and Drug Administration (FDA) of interim safety, pharmacokinetic and pharmacodynamic data from the first three cohorts of the SAD healthy volunteer portion of the Phase 1 study.


In July 2021, Kymera initiated dosing of healthy volunteers in the MAD portion of the Phase 1 trial of KT-474. The multiple ascending dose portion of the trial is designed to evaluate repeat daily dosing of KT-474 for 14 days, beginning with the 25 mg dose, in healthy volunteers randomized 9:3 to KT-474 or placebo. Kymera expects to present updated results from the healthy volunteer SAD and MAD portions of the trial in 4Q21, including IRAK4 degradation in both skin and PBMC and effects on inflammatory biomarkers, establishing the first proof-of-biology.


Expected Milestones:


Presentation of Phase 1 proof-of-biology in healthy volunteers (4Q21)


Presentation of Phase 1 proof-of-biology in AD and HS patient cohort (1H22)


IRAKIMiD Degrader Program

IRAKIMiDs are novel heterobifunctional degraders designed to degrade both IRAK4 and IMiD substrates, including Ikaros and Aiolos, with a single small molecule. IRAKIMiDs synergistically target both the MYD88-NFkB and IRF4-Type 1 interferon pathways to enhance and broaden anti-tumor activity in multiple contexts, such as MYD88-mutant diffuse large B-cell lymphoma (DLBCL). KT-413 is being developed initially for the treatment of relapsed/refractory MYD88-mutant DLBCL, with the potential to expand into other MYD88-mutant indications and IL-1R/NFkB-driven malignancies. Kymera plans to submit an Investigational New Drug Application (IND) to the FDA in the second half of 2021 and, if cleared, initiate a Phase 1 clinical trial in patients thereafter.


Recent Updates:


In June 2021, Kymera presented new preclinical data on its IRAKIMiD degrader KT-413’s potential as both a monotherapy and in combination with other anticancer agents. KT-413 showed profound single-agent activity and synergistic activity in driving deep tumor regressions in combination with other therapies in preclinical models, suggesting the potential for therapeutically relevant drug combinations in MYD88-mutant DLBCL. The data were featured in an oral presentation at the 16th Annual International Conference on Malignant Lymphoma (ICML) virtual meeting.


Expected Milestones:


Submission of IND application to evaluate KT-413 in Phase 1 clinical trial in relapsed/refractory B cell lymphomas, including MYD88-mutant DLBCL and subsequent initiation of Phase 1 clinical trial (2H21)


Presentation of additional KT-413 preclinical data and potential indication expansion strategies (2H21)





Establish Phase 1 proof-of-biology and initial clinical proof-of-concept in patients (2022)


STAT3 Degrader Program

Kymera is developing selective STAT3 degraders for the treatment of hematological malignancies and solid tumors, as well as autoimmune diseases and fibrosis. STAT3 is a transcription factor activated through a variety of different cytokine and growth factor receptors via Janus kinases (JAKs), as well as through oncogenic fusion proteins and mutations in STAT3 itself. Long considered an “undruggable” target, STAT3 hyperactivation is prominent in numerous liquid and solid tumors, including clinically aggressive lymphomas. Kymera’s STAT3 degraders have demonstrated strong anti-tumor effects in mouse xenograft and syngeneic models of liquid and solid tumors. Kymera’s lead STAT3 degrader candidate, KT-333, is currently in preclinical development. Kymera plans to submit an IND to the FDA in the fourth quarter of 2021 and, if cleared, initiate a Phase 1 clinical trial in patients thereafter.


Recent Updates:


In July 2021, Kymera presented new preclinical data demonstrating the therapeutic potential of its STAT3 degraders for the treatment of peripheral T-cell lymphoma (PTCL). The data demonstrate Kymera’s ability to degrade mutant and wild-type STAT3 and the broad therapeutic potential for the treatment of peripheral T-cell lymphoma subtypes with aberrant STAT3 activation, including subtypes of PTCL such as ALK-positive anaplastic large cell lymphoma (ALCL), ALK-negative ALCL, and NK/T cell lymphoma. The data were featured in a presentation at the virtual 13th Annual T-Cell Lymphoma Forum.


Expected Milestones:


Presentation of additional preclinical data in liquid and solid tumors (2H21)


Submission of IND application to evaluate KT-333 in a Phase 1 clinical trial in relapsed/refractory liquid and solid tumors and subsequent initiation of a Phase 1 clinical trial (4Q21)


Establish Phase 1 proof-of-biology and initial clinical proof-of-concept in patients (2022)


Platform and Discovery Programs

Kymera is also actively advancing a broad pipeline of preclinical programs across a wide variety of diseases, both internally and in collaboration with existing partners Vertex Pharmaceuticals and Sanofi. The internal programs continue to be focused on undrugged or inadequately drugged nodes within highly validated pathways in immune-inflammatory and oncology indications. Kymera is also developing a new generation of tissue-selective or -restricted degrader medicines with the goal of drugging an entirely new set of protein targets.


Recent Updates:


In May 2021, Kymera presented new data demonstrating proof-of-concept for its PegasusTM platform, including the identification and characterization of a novel and previously unliganded E3 ligase with restricted expression in healthy tissues while broadly expressed in cancer cells, as determined by proteomics. Kymera discovered novel ligands for this ligase using state-of-the-art hit finding techniques and subsequently designed a novel proof-of-concept STAT3 degrader compound based on this novel E3 ligase. The degrader demonstrated potent and dose-dependent degradation of STAT3 across multiple cancer and immune cell lines. The data were presented at the inaugural Ligase Targeting Drug Development Summit.


Expected Milestones:


Continue pipeline expansion by advancing discovery programs toward Development Candidate nomination and subsequent IND-enabling studies






Corporate Updates


In June 2021, the Company appointed Elaine Caughey, MBA, as Chief Business Officer. Ms. Caughey joins Kymera with over 20 years of experience in the biotechnology industry, including leadership roles in corporate development, business and commercial operations, new product strategy, and investing.


In July 2021, the Company announced the appointments of Karen Weisbach, as Vice President, People and Culture and Jolly Bhatia as Vice President, Quality.



Ms. Weisbach joins Kymera with over 15 years of experience in human resources and operations, designing values-based initiatives to enhance company culture, improve employee experience and manage change in dynamic, innovative organizations in the biopharmaceutical industry.



Mr. Bhatia joins Kymera with approximately 25 years in quality oversight of manufacturing and clinical trial lifecycle activities including process and product development, clinical and commercial supply chains, and new product launch.


In July 2021, Kymera announced the closing of its upsized underwritten public offering of 5,468,250 shares of common stock at a public offering price of $47.00 per share, which included 713,250 shares issued upon the exercise in full by the underwriters of their option to purchase additional shares of common stock. The net proceeds to Kymera from the offering were approximately $243.1 million, after deducting underwriting discounts, commissions and offering expenses.


Kymera plans to host its inaugural R&D Day in 4Q21 to unveil its next pathways/programs approaching clinical development, and expanded view of platform capabilities, as well as to outline the Company’s vision and goals for the next five years.


Second Quarter 2021 Financial Results

Collaboration Revenues: Collaboration revenues were $18.5 million for the second quarter of 2021, compared to $3.3 million for the same period of 2020. Collaboration revenues in 2021 include revenue from our Sanofi and Vertex collaborations.


Research and Development Expenses: Research and development expenses were $35.2 million for the second quarter of 2021, compared to $13.8 million for the same period of 2020.
