The company expects to report pivotal data from this trial in 2025.\nPhase 2 portion of the ALKOVE-1 trial of NVL-655 for TKI-naïve and TKI pre-treated patients with advanced ALK-positive NSCLC and other solid tumors: Between February 2024 and September 1, 2024, 229 patients were enrolled in the ongoing single-arm, multi-cohort Phase 2 portion of the ALKOVE-1 trial, which is designed with registrational intent for TKI pre-treated patients. The company also expects to report pivotal data from this trial in 2025.\nALKAZAR Phase 3 randomized, controlled trial of NVL-655 for TKI-naïve patients with advanced ALK-positive NSCLC: The Phase 3 ALKAZAR trial will be a global, randomized, controlled trial designed to evaluate NVL-655 versus the current standard of care for the treatment of patients with TKI-naïve ALK-positive NSCLC. Patients will be randomized 1:1 to receive NVL-655 monotherapy or ALECENSA® (alectinib) monotherapy, reflecting input from collaborating physician-scientists and alignment with the U.S. Food and Drug Administration (FDA). The company plans to initiate the ALKAZAR study in the first half of 2025.\n\n\"The Phase 1 portions of our ARROS-1 and ALKOVE-1 studies have established preliminary clinical proof-of-concept for zidesamtinib and NVL-655 as selective, brain-penetrant, TRK-sparing TKIs that have the potential to move up the treatment paradigm, as demonstrated by the preliminary safety profile indicating favorable tolerability, and the durability of responses observed across patient subsets presented today at ESMO,\" said Christopher Turner, M.D., Chief Medical Officer at Nuvalent. \"We believe zidesamtinib and NVL-655 have the potential to not only address clear medical needs in the third line where no approved therapies have demonstrated clinical benefit, but also provide differentiated options in the second line including for patients who have experienced disease progression due to CNS metastases or resistance mutations, and ultimately deliver deep, durable responses in the front line.\"\n\"We are grateful for the strong investigator enthusiasm for our programs, exemplified by the accelerated Phase 2 enrollment in our ARROS-1 and ALKOVE-1 trials. We now anticipate reporting pivotal datasets from both Phase 2 trials in 2025,\" said Darlene Noci, A.L.M., Chief Development Officer at Nuvalent. \"With the announcement of our planned ALKAZAR randomized, controlled Phase 3 study, we are thrilled to also establish a potential registration path for TKI-naïve patients with advanced ALK-positive NSCLC. Through our multi-pronged strategies, our goal is to bring potential best-in-class therapies that can move up the treatment paradigm to patients as efficiently as possible. We look forward to initiating the ALKAZAR study in the first half of 2025.\"\nThe ALKAZAR trial is designed to enroll approximately 450 patients with TKI-naïve ALK-positive NSCLC. The primary endpoint is progression free survival (PFS) based on Blinded Independent Central Review (BICR). Secondary endpoints include PFS based on investigator's assessment, and BICR assessment of objective response rate (ORR), intracranial objective response rate (IC-ORR), overall survival (OS), and safety.\n\"At the outset of this year, we announced our OnTarget 2026 operating plan delineating our path towards a potential first approval in 2026 from our pipeline of novel kinase inhibitors. With today's updates, we have successfully achieved all of the supporting milestones laid out for 2024 and believe we are now on track to share pivotal datasets from both of our parallel-lead programs in 2025, a testament to the tireless dedication of our team,\" said James Porter, Ph.D., Chief Executive Officer at Nuvalent. \"I am incredibly proud of what we have accomplished thus far and am optimistic about the road ahead. With the foundation of encouraging Phase 1 proof-of-concept data, strong enrollment momentum in our global Phase 2 trials, alignment with the FDA on the design of our Phase 3 ALKAZAR study, and the dedication of our proven team, we are confident in our ability to continue advancing our programs towards our goal of delivering them as quickly as possible to the patients that need them.\"\nARROS-1 Phase 1 Update at ESMO 2024\nFrom January 2022 to August 2023, the Phase 1 portion of ARROS-1 enrolled 104 patients (99 NSCLC, 5 other solid tumors). Patients received zidesamtinib orally at dose levels ranging from 25 to 150 mg once daily (QD), and 100 mg QD was selected as the recommended Phase 2 dose (RP2D). No clinically significant exposure-response relationships for safety and efficacy were observed and data are reported across all doses.\nThe patient population was heavily pre-treated, with a median of 3 prior lines of therapy (range 1 – 11). 69% (72/104) of patients had ≥2 prior ROS1 TKIs, and 66% (69/104) had prior chemotherapy. Notably, 55% (57/104) of patients received prior lorlatinib and 21% (22/104) received prior repotrectinib, highlighting the differentiated nature of this population from prior trials of other ROS1 inhibitors. 52% (54/104) had history of CNS metastases, including cases of disease progression following treatment with the brain-penetrant TKIs lorlatinib and/or repotrectinib.\nAs of the cut-off date of July 1, 2024, 71 pre-treated patients with ROS1-positive NSCLC were response-evaluable. The median follow-up for the all-treated population was 12.1 months (range, 0.8 – 29.4).\nTreatment with zidesamtinib resulted in durable clinical responses (ORR by RECIST 1.1) across key subgroups of response-evaluable patients. As of the data cut-off date:\n\n\n\n\nROS1-positive NSCLC response-evaluable  \nZidesamtinib, All Doses  \n\n\nORR \nmDOR(months) \nDOR ≥  6 months* \nDOR ≥  12 months* \n\n\nAny Prior Therapies (1 – 4 prior ROS1 TKIs ± chemotherapy) \n44%  (31/71, 2 CRs) \nNR \n83 % \n67 % \n\n\nRepotrectinib-naive \n51%  (27/53) \nNR \n88 % \n71 % \n\n\n≥2 prior ROS1 TKIs** (≥ 3rd Line; ± chemotherapy) \n41% (21/51) \n12.1 \n75 % \n54 % \n\n\nPrior crizotinib only  (2nd Line; ± chemotherapy) \n73% (8/11) \nNR*** \n100%*** \n100%*** \n\n\nNR = not reached * Analyses of DOR based on Kaplan-Meier estimates. ** Zidesamtinib has received FDA breakthrough therapy designation for the treatment of patients with ROS1-positive metastatic NSCLCwho have been previously treated with 2 or more ROS1 TKIs. *** No disease progression among responders. \n\n\n\n\nIn the subset of patients with confirmed ROS1 G2032R resistance mutation, the ORR was 72% (13/18) for repotrectinib-naïve patients.\nIC-ORR was 50% (4/8) in intracranial response-evaluable patients with measurable CNS lesions, of which 7/8 patients had been previously treated with the brain-penetrant TKIs lorlatinib and/or repotrectinib. The mIC-DOR was not reached, with no CNS progression observed among confirmed CNS responders.\nZidesamtinib was well-tolerated with a preliminary safety profile that was favorable and consistent with its ROS1-selective, TRK sparing design. Among the 104 treated patients at all doses, the most frequent treatment-related adverse events (TRAEs) were oedema peripheral (19%), ALT increase, AST increase, and weight increase (each 11%). Among these most frequent TRAEs, there was a single grade 3 event of weight increase. No discontinuation due to TRAEs occurred. Dose reductions due to TRAEs occurred in 8% of patients. A maximum tolerated dose was not identified.\nThe company believes these preliminary data demonstrate the potential for zidesamtinib to address a medical need for the third-line treatment of ROS1-positive NSCLC where no approved therapies have demonstrated clinical benefit, and to provide a differentiated option in the second line where there also remains a medical need. Additionally, the company believes that these data in heavily pre-treated patients could have the potential to translate to deep, durable responses in the front-line setting.\nFurther investigation of zidesamtinib for both TKI-naïve and TKI pretreated patients with ROS1-positive NSCLC is underway in the Phase 2 portion of the ARROS-1 clinical trial, designed with registrational intent. The company expects to report pivotal data in 2025.\nALKOVE-1 Phase 1 Update at ESMO 2024\nFrom June 2022 to February 2024, the Phase 1 portion of ALKOVE-1 enrolled 133 patients (131 NSCLC, 2 other solid tumors). Patients received NVL-655 orally at dose levels ranging from 15 to 200 mg QD, and 150 mg QD was selected as the RP2D.\nThe patient population was heavily pre-treated, with a median of 3 prior lines of therapy (range 1 – 9). 46% (61/133) of patients had ≥3 prior ALK TKIs, and 56% (74/133) had prior chemotherapy. Notably, 84% (111/133) of patients received prior lorlatinib and 51% (68/133) had any secondary ALK resistance mutation including 26% (34/133) with compound (≥2) ALK mutations, highlighting the differentiated nature of this population from prior trials of investigational ALK inhibitors. 56% (75/133) had history of CNS metastases, including cases of disease progression following treatment with the brain-penetrant TKI lorlatinib.\nAs of the cut-off date of June 15, 2024, 103 heavily pre-treated patients with ALK-positive NSCLC treated across all doses were response-evaluable, of whom 39 were treated at the RP2D. The median follow-up for the all-treated population was 8.0 months (range 0.2, 22.5).\nTreatment with NVL-655 resulted in durable clinical responses (ORR by RECIST 1.1) across key subgroups of response-evaluable patients treated at the RP2D and across all dose levels. As of the data cut-off date:\n\n\n\n\nALK-positive NSCLC response-evaluable \nNVL-655 at RP2D \nNVL-655, All Doses \n\n\nORR \nmDOR(months) \nDOR ≥ 6 months* \nORR \nmDOR(months) \nDOR ≥ 6 months* \n\n\nAny Prior Therapies (1 – 5 prior ALK TKIs ± chemotherapy) \n38% (15/39) \nNR \n100 % \n38% (39/103) \n14.4 \n78 % \n\n\nLorlatinib pre-treated  (≥ 3rd Line**; ± chemotherapy) \n35% (11/31) \nNR \n100 % \n35% (30/85) \n9.2 \n75 % \n\n\nWith compound ALK resistance mutations \n64% (7/11) \nNR \n100 % \n54% (15/28) \n14.4 \n80 % \n\n\nLorlatinib-naïve  (≥ 2nd Line; ± chemotherapy) \n57% (4/7) \nNR \n100 % \n53% (9/17) \nNR \n88 % \n\n\nWith ALK resistance mutation(s) \n80% (4/5) \nNR*** \n100%*** \n88% (7/8) \nNR*** \n100%*** \n\n\nNR = not reached * Analyses of DOR based on Kaplan-Meier estimates. ** NVL-655 has received FDA breakthrough therapy designation for the treatment of patients with locally advanced or metastatic ALK-positive NSCLCwho have been previously treated with 2 or more ALK TKIs *** No disease progression among responders. \n\n\n\n\nCNS responses were observed in patients with either measurable or unmeasurable CNS lesions across all doses, including complete intracranial responses in patients who previously received the brain-penetrant TKI lorlatinib. No CNS progression was observed among all confirmed CNS responders.\nNVL-655 was well-tolerated with a preliminary safety profile that was favorable and consistent with its ALK-selective, TRK sparing design. Among the 133 patients treated at all doses, the most frequent TRAEs were ALT increase (34%), AST increase (30%), constipation (16%), dysgeusia (13%), and nausea (12%). Among these most frequent TRAEs, 13% of patients experienced grade 3 ALT increase, one patient experienced grade 4 ALT increase, and 9% of patients experienced grade 3 AST increase. Transaminase elevations were generally transient and reversible.\nDiscontinuations due to TRAEs occurred in 2% of patients and dose-reductions occurred in 15% of patients. A maximum tolerated dose was not identified.\nThe company believes these preliminary data demonstrate the potential for NVL-655 to address a medical need for the third-line treatment of ALK-positive NSCLC where no approved therapies have demonstrated clinical benefit, and to provide a differentiated option in the second line. The ongoing Phase 2 portion of the ALKOVE-1 clinical trial is designed with registrational intent for TKI pre-treated patients with ALK-positive NSCLC, and the company expects to report pivotal data in 2025.\nAdditionally, the company believes that these data in heavily pre-treated patients could have the potential to translate to deep, durable responses in the front-line setting. The company plans to initiate the Phase 3 randomized, controlled, ALKAZAR study with registrational intent for TKI-naïve patients in the first half of 2025.\nConference Call Information\nFollowing oral presentations at the ESMO Congress 2024 in Barcelona, Spain, management will host a live webcast and conference call on Saturday, September 14, 2024 at 8:30 a.m. ET/2:30 p.m. CEST.\nTo access the call, register online here for the live webcast or dial +1 (800) 836-8184 (domestic) or +1 (646) 357-8785 (international) at least 10 minutes prior to the start time and ask to be joined to the Nuvalent call.

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.\nZidesamtinib is currently being investigated in the ARROS-1 trial (NCT05118789), a first-in-human Phase 1/2 clinical trial for patients with advanced ROS1-positive NSCLC and other solid tumors. The completed Phase 1 portion enrolled ROS1-positive NSCLC patients who previously received at least one ROS1 TKI, or patients with other ROS1-positive solid tumors who had been previously treated. The Phase 1 portion of the trial was designed to evaluate the overall safety and tolerability of NVL-520, with additional objectives including determination of the recommended Phase 2 dose (RP2D), characterization of the pharmacokinetic profile, and evaluation of preliminary anti-tumor activity. The ongoing global, single arm, open label Phase 2 portion is designed with registrational intent for TKI naïve and TKI pre-treated patients with ROS1-positive NSCLC.\nAbout NVL-655 and the ALKOVE-1 Phase 1/2 Clinical Trial\nNVL-655 is a novel brain-penetrant ALK-selective inhibitor created with the aim to overcome limitations observed with currently available ALK inhibitors. NVL-655 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, NVL-655 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. NVL-655 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. \nNVL-655 is currently being evaluated in the Phase 2 portion of the ALKOVE-1 Phase 1/2 clinical trial, a first-in-human study of NVL-655 in patients with advanced ALK-positive NSCLC and other solid tumors (NCT05384626). The completed Phase 1 portion enrolled ALK-positive NSCLC patients who previously received at least one ALK TKI and patients with other ALK-positive solid tumors who had been previously treated with at least one prior systemic anticancer therapy. The primary objectives were to determine the recommended Phase 2 dose (RP2D) and if applicable, the maximum tolerated dose (MTD) of NVL-655 in patients with ALK-positive solid tumors. Additional objectives included characterization of the overall safety, tolerability, and pharmacokinetic profile, and evaluation of the preliminary anti-tumor activity of NVL-655. The ongoing global, single arm, open label Phase 2 portion is designed with registrational intent for TKI pre-treated patients with ALK-positive NSCLC and to enable preliminary investigation for patients with ALK-positive NSCLC who are TKI naïve.\nAbout NuvalentNuvalent, Inc.
