As part of this plan, Nuvalent anticipates the following 2025 milestones:

• Report pivotal data for tyrosine kinase inhibitor (TKI) pre-treated patients with advanced ROS1-positive non-small cell lung cancer (NSCLC) from its ARROS-1 Phase 1/2 trial of zidesamtinib in the first half of 2025;

• Submit a New Drug Application (NDA) for zidesamtinib with initial target indication of TKI pre-treated patients with advanced ROS1-positive NSCLC by mid-year 2025;

• Report pivotal data for TKI pre-treated patients with advanced ALK-positive NSCLC from its ALKOVE-1 Phase 1/2 trial of neladalkib (NVL-655) by year-end 2025;

• Initiate the ALKAZAR Phase 3 randomized, controlled trial of neladalkib for TKI-naïve patients with ALK-positive NSCLC in the first half of 2025; and

• Progress the HEROEX-1 Phase 1a/1b trial of NVL-330 for patients with advanced HER2-altered NSCLC.

With the achievement of these milestones, the company anticipates that the first potential approval from its pipeline of novel kinase inhibitors will be for zidesamtinib for the treatment of TKI pre-treated ROS1-positive NSCLC in 2026.

"2025 marks our opportunity to transition to becoming a fully integrated commercial-stage biopharmaceutical company. Throughout this period of growth and evolution, our strategy remains rooted in our commitment to our core value of Patient Impact, and our responsibility to the patients and treating physicians who continue to support our clinical trials," said James Porter, Ph.D., Chief Executive Officer at Nuvalent. "Enrollment momentum in the Phase 2 portions of our ARROS-1 and ALKOVE-1 clinical trials has further accelerated following our presentation of updated Phase 1 data at ESMO (Free ESMO Whitepaper) 2024, reinforcing our plan to report pivotal data from both programs this year. We believe this enthusiasm is a clear demonstration of the medical need for patients with ROS1- and ALK-positive NSCLC, and of our responsibility to bring new treatment options to TKI pre-treated patients as quickly as possible."

"Parallel development paths are in place towards our ultimate goal to provide new, potential best-in-class treatment options to all patients with ROS1- or ALK-positive NSCLC," said Darlene Noci, A.L.M., Chief Development Officer at Nuvalent. "For zidesamtinib, we plan to submit an NDA this year with an initial target indication for TKI pre-treated patients with ROS1-positive NSCLC, where we believe zidesamtinib has demonstrated the potential to address a medical need. We expect to report topline pivotal data from this population in the first half of 2025. In parallel, we continue a collaborative dialogue with the FDA on accelerated opportunities towards a potential line-agnostic indication supported by our ongoing TKI-naïve cohort in the Phase 2 portion of our ARROS-1 trial."

Ms. Noci continued, "Similarly for neladalkib, we expect our initial NDA submission to be for TKI pre-treated patients with ALK-positive NSCLC, supported by topline pivotal data from the ALKOVE-1 trial that we expect to report by year-end 2025. Additionally, we remain on-track to initiate the Phase 3 randomized, controlled ALKAZAR trial for TKI-naïve patients in the first half of this year, a critical step towards our ultimate goal of moving neladalkib up the treatment paradigm."

"We believe we have the right team in place and are well resourced with cash runway into 2028 to support the advancement of our clinical programs and ongoing buildout of a commercial infrastructure," said Alexandra Balcom, Chief Financial Officer at Nuvalent. "Beyond our parallel-lead programs, we remain committed to advancement of our HEROEX-1 Phase 1a/1b trial and robust discovery pipeline for sustainable long-term growth."

About Zidesamtinib

Zidesamtinib is a novel brain-penetrant ROS1-selective inhibitor created with the aim to overcome limitations observed with currently available ROS1 inhibitors. Zidesamtinib is designed to remain active in tumors that have developed resistance to currently available ROS1 inhibitors, including tumors with treatment-emergent ROS1 mutations such as G2032R. In addition, zidesamtinib is designed for central nervous system (CNS) penetrance to improve treatment options for patients with brain metastases, and to avoid inhibition of the structurally related tropomyosin receptor kinase (TRK) family. Together, these characteristics have the potential to avoid TRK-related CNS adverse events seen with dual TRK/ROS1 inhibitors and to drive deep, durable responses for patients across all lines of therapy. Zidesamtinib has received breakthrough therapy designation for the treatment of patients with ROS1-positive metastatic non-small cell lung cancer (NSCLC) who have been previously treated with 2 or more ROS1 tyrosine kinase inhibitors and orphan drug designation for ROS1-positive NSCLC.

About Neladalkib (NVL-655)

Neladalkib is a novel brain-penetrant ALK-selective inhibitor created with the aim to overcome limitations observed with currently available ALK inhibitors. Neladalkib is designed to remain active in tumors that have developed resistance to first-, second-, and third-generation ALK inhibitors, including tumors with single or compound treatment-emergent ALK mutations such as G1202R. In addition, neladalkib is designed for central nervous system (CNS) penetrance to improve treatment options for patients with brain metastases, and to avoid inhibition of the structurally related tropomyosin receptor kinase (TRK) family. Together, these characteristics have the potential to avoid TRK-related CNS adverse events seen with dual TRK/ALK inhibitors and to drive deep, durable responses for patients across all lines of therapy. Neladalkib has received breakthrough therapy designation for the treatment of patients with locally advanced or metastatic ALK-positive non-small cell lung cancer (NSCLC) who have been previously treated with 2 or more ALK tyrosine kinase inhibitors and orphan drug designation for ALK-positive NSCLC.

About NVL-330

NVL-330 is a novel brain-penetrant HER2-selective tyrosine kinase inhibitor designed to address the combined medical need of treating HER2-mutant tumors, including those with HER2 exon 20 insertion mutations, avoiding treatment related adverse events due to off-target inhibition of wild-type EGFR, and treating brain metastases.

The approval by the NMPA was based on data from the confirmatory Phase IIIb clinical trial in patients with MET exon 14 skipping alteration NSCLC (NCT04923945). Preliminary efficacy and safety data from the first-line cohort were presented during the IASLC World Conference on Lung Cancer (WCLC) in September 2023. Final data from the confirmatory Phase IIIb trial were presented at the European Lung Cancer Congress in March 2024.

In treatment-naïve patients, objective response rate ("ORR") was 62.1%, disease control rate ("DCR") was 92.0% and median duration of response ("DoR") was 12.5 months, as assessed by an independent review committee. Median progression free survival ("PFS") was 13.7 months and median overall survival ("OS") was not reached with median follow-up of 20.8 months. In previously treated patients, ORR was 39.2%, DCR was 92.4% and median DoR was 11.1 months, as assessed by an independent review committee. Median PFS was 11.0 months and median OS was not mature with median follow-up of 12.5 months. Responses occurred early (time to response 1.4-1.6 months) in both treatment-naïve and previously treated patients. The safety profile was tolerable and no new safety signals were observed. The most common drug-related treatment-emergent adverse events of Grade 3 or above (5% or more of patients) were abnormal hepatic function (16.9%), increased alanine aminotransferase (14.5%), increased aspartate aminotransferase (12.0%), peripheral oedema (6.0%) and increased gamma-glutamyltransferase (6.0%).

"This Phase IIIb confirmatory study of ORPATHYS is one of the largest Phase III clinical trials conducted in China for this patient population to date. ORPATHYS has demonstrated clear efficacy and tolerability in both first-line and second-line settings, underscoring its potential as a standard treatment option for NSCLC with MET exon 14 skipping alterations," said Prof. Shun Lu, Chief of the Shanghai Lung Cancer Center at Shanghai Chest Hospital, School of Medicine, Shanghai Jiaotong University, and Principal Investigator of the confirmatory Phase IIIb study. "By making ORPATHYS available as a first-line treatment, we are able to provide our patients with an effective targeted therapy earlier in their treatment journey. We look forward to introducing this novel treatment and optimizing the treatment strategy for this challenging patient population to improve their outcomes and quality of life."

"The approval marks an exciting step forward in addressing the unmet needs of NSCLC patients with MET exon 14 skipping alteration. It not only validates our research but also emphasizes our dedication to addressing unmet medical needs through targeted drug development," said Dr. Michael Shi, Head of R&D and Chief Medical Officer of HUTCHMED. "We are focused on advancing our research and expanding access to ORPATHYS, ultimately improving the treatment landscape for those affected by this challenging form of lung cancer. We also remain committed to further exploring ORPATHYS in other MET driven diseases in order to help more patients who may benefit from this targeted treatment."

"Today’s approval reinforces ORPATHYS as a transformative option for the treatment of biomarker-driven lung cancer, and we are proud that we can now offer this therapy to both first-line and second-line patients in China with advanced NSCLC with MET exon 14 skipping alterations," said Ms. Mary Guan, General Manager of AstraZeneca China Oncology Business. "Through our partnership with HUTCHMED, we are advancing ORPATHYS to address resistance to EGFR-TKIs1, unlocking new possibilities for treating MET-altered and amplified cancers, and expanding the reach of this innovative therapy to even more patients with this form of lung cancer."

Savolitinib was launched and is marketed under the brand name ORPATHYS by our partner, AstraZeneca, for this patient population, representing the first selective MET inhibitor approved in China.

About NSCLC and MET aberrations

Lung cancer is the leading cause of cancer death, accounting for about one-fifth of all cancer deaths.2 More than a third of the world’s lung cancer patients are in China. Lung cancer is broadly split into NSCLC and small cell lung cancer, with 80-85% classified as NSCLC.3 The majority of NSCLC patients (approximately 75%) are diagnosed with advanced disease, and approximately 10-15% of NSCLC patients in the US and Europe and 30-40% of patients in Asia have EGFR-mutated NSCLC.4,5,6,7

MET is a tyrosine kinase receptor that has an essential role in normal cell development.8 MET overexpression and/or amplification can lead to tumor growth and the metastatic progression of cancer cells, and is one of the mechanisms of acquired resistance to EGFR TKI for metastatic EGFR-mutated NSCLC.8,9 Approximately 2-3% of NSCLC patients have tumors with MET exon 14 skipping alterations, a targetable mutation in the MET gene.10 MET aberration is a major mechanism for acquired resistance to both first/second-generation EGFR TKIs as well as third-generation EGFR TKIs like osimertinib. Among patients who experience disease progression post-osimertinib treatment, approximately 15-50% present with MET aberration.11,12,13,14,15 The prevalence of MET aberration depends on the sample type, detection method and assay thresholds used.16

About ORPATHYS (savolitinib)

ORPATHYS is an oral, potent and highly selective MET TKI that has demonstrated clinical activity in advanced solid tumors. It blocks atypical activation of the MET receptor tyrosine kinase pathway that occurs because of mutations (such as exon 14 skipping alterations or other point mutations), gene amplification or protein overexpression.

ORPATHYS was previously granted conditional approval in China in June 2021 for the treatment of patients with NSCLC with MET exon 14 skipping alterations who have progressed following prior systemic therapy or are unable to receive chemotherapy. ORPATHYS is the first selective MET inhibitor approved in China. It has been included in the National Reimbursement Drug List of China (NRDL) since March 2023. It is also currently under clinical development for multiple tumor types, including lung, kidney and gastric cancers, as a single treatment and in combination with other medicines.

In 2011, AstraZeneca and HUTCHMED entered a global licensing and collaboration agreement to jointly develop and commercialize ORPATHYS. Joint development of ORPATHYS in China is led by HUTCHMED, while AstraZeneca leads development outside of China. HUTCHMED is responsible for the marketing authorization, manufacturing and supply of ORPATHYS in China. AstraZeneca is responsible for the commercialization of ORPATHYS in China and worldwide. Sales of ORPATHYS are recognized by AstraZeneca.

On January 14, 2025 Greenwich LifeSciences, Inc.

According to the latest data collected by the European Cancer Information System (click here), a total of 75,267 new cases of breast cancer were diagnosed in Germany in 2022, which is the most common cancer diagnosed in women, representing approximately 29% of all cancers in women. Breast cancer is the leading cause of death from cancer in women in Germany with 20,601 deaths in 2022.

Professor Sibylle Loibl, who serves on the FLAMINGO-01 Steering Committee, expressed her excitement about the partnership, stating "We are pleased to collaborate with Greenwich LifeSciences on this important immunotherapy study. With a focus on HER2+ high-risk patients who have not achieved a pathologic complete response (pCR), but also those pCR patients who are having a high-risk of relapse despite achieving a pCR, based on GBG data (von Mackelenbergh 2023), this trial has the potential to further improve our understanding of preventing breast cancer recurrences and improving patient outcomes. We are also very pleased that the first patient from Germany was randomized and treated in October 2024."

Dr. Sibylle Loibl serves as Professor (apl) Goethe University Frankfurt/M, Clinical Consultant Centre for Haematology and Oncology/Bethanien Frankfurt/M, CEO of GBG Forschungs GmbH, and Chair of the German Breast Group. She is one of the founding members of GBG. She is well known for her leadership in developing new treatments and organizing large international clinical trials. By 2023, she had written over 1000 original articles, reviews and book chapters and reached an audience of over 13,000 followers in the last year.

Dr. Marcus Schmidt, the national Principal Investigator (PI) for Germany for FLAMINGO-01 and Professor of Molecular Oncology at the University Medical Center Mainz, highlighted the significance of the study in advancing cancer immunotherapy: "The FLAMINGO-01 trial presents a unique opportunity to evaluate GLSI-100’s efficacy in preventing recurrence among HER2-positive breast cancer patients. This trial could pave the way for new treatment paradigms and further the potential of immunotherapies in breast cancer care."

Jaye Thompson, VP of Clinical and Regulatory Affairs, commented, "Adding FLAMINGO-01 sites in Germany will provide access to the largest number of patients in Europe, and GBG has an excellent reputation of providing high quality data. We are fortunate to have a relationship with GBG and the opportunity to offer FLAMINGO-01 to patients in Germany."

Snehal Patel, CEO of Greenwich LifeSciences, added, "Our collaboration with GBG reflects the strength of our mutual commitment to reducing metastatic breast cancer with the latest scientific advancements. By working with one of the world’s leading breast cancer research groups, and with Dr. Loibl’s active participation on our Steering Committee, we are confident that this partnership will accelerate progress and bring life-saving innovations to the forefront."

About FLAMINGO-01 and GLSI-100

FLAMINGO-01 (NCT05232916) is a Phase III clinical trial designed to evaluate the safety and efficacy of GLSI-100 (GP2 + GM-CSF) in HER2 positive breast cancer patients who had residual disease or high-risk pathologic complete response at surgery and who have completed both neoadjuvant and postoperative adjuvant trastuzumab based treatment. The trial is led by Baylor College of Medicine and currently includes US clinical sites from university-based hospitals and cooperative networks with plans to expand into Europe and to open up to 150 sites globally. In the double-blinded arms of the Phase III trial, approximately 500 HLA-A*02 patients will be randomized to GLSI-100 or placebo, and up to 250 patients of other HLA types will be treated with GLSI-100 in a third arm. The trial has been designed to detect a hazard ratio of 0.3 in invasive breast cancer-free survival, where 28 events will be required. An interim analysis for superiority and futility will be conducted when at least half of those events, 14, have occurred. This sample size provides 80% power if the annual rate of events in placebo-treated subjects is 2.4% or greater.

About Breast Cancer and HER2/neu Positivity

One in eight U.S. women will develop invasive breast cancer over her lifetime, with approximately 300,000 new breast cancer patients and 4 million breast cancer survivors. HER2 (human epidermal growth factor receptor 2) protein is a cell surface receptor protein that is expressed in a variety of common cancers, including in 75% of breast cancers at low (1+), intermediate (2+), and high (3+ or over-expressor) levels.
