Alignment with US Food and Drug Administration on a Recommended Phase 2 Dose for NVL-655 of 150 mg once daily Phase 2 Designed with Registrational Intent for TKI Pre-Treated Patients with ALK-Positive NSCLC and Enables Preliminary Evaluation in the TKI-naïve Setting CAMBRIDGE, Mass., Feb. 12, 2024 /PRNewswire/ -- Nuvalent, Inc. (Nasdaq: NUVL), a clinical-stage biopharmaceutical company focused on creating precisely targeted therapies for clinically proven kinase targets in cancer, today announced the initiation of the Phase 2 portion of ALKOVE-1, its Phase 1/2 clinical trial of NVL-655 for patients with ALK-positive non-small cell lung cancer (NSCLC) and other solid tumors, following alignment with the US Food and Drug Administration (FDA) on a recommended Phase 2 dose (RP2D) of 150 mg once daily (QD). NVL-655 is a novel brain-penetrant ALK-selective tyrosine kinase inhibitor (TKI) created with the aim to simultaneously overcome the clinical challenges of emergent treatment resistance, brain metastases, and off-target central nervous system (CNS) adverse events associated with inhibition of the structurally-related tropomyosin receptor kinase (TRK) family that may limit the use of currently available ALK TKIs. In the Phase 1 portion of ALKOVE-1, six dose levels (15 mg to 200 mg QD) of NVL-655 were evaluated in heavily pre-treated patients with ALK-positive solid tumors, and a maximum tolerated dose was not reached. The RP2D of 150 mg QD maintained steady state plasma levels above target efficacy thresholds (ALK wild type fusions and ALK single and compound mutations in both the periphery and in the CNS). "The transition of our NVL-655 program into Phase 2 advances a second, parallel opportunity towards our goal of bringing potential best-in-class therapies to patients as efficiently as possible," said Darlene Noci, A.L.M., Chief Development Officer at Nuvalent. "This sense of urgency is reflected in the thoughtful design of the Phase 2 portion of the ALKOVE-1 trial which aims to accelerate the clinical investigation that may support a potential marketing application towards an initial approval for previously treated patients with ALK-positive NSCLC. The Phase 2 portion also includes a TKI-naïve cohort which may provide an opportunity to generate early data, and could be conducted in parallel with a front-line registration-directed trial." Ms. Noci continued, "Support for the design of the Phase 2 cohorts includes the broad clinical activity and favorable tolerability observed to date in heavily pre-treated patients in the Phase 1 portion of ALKOVE-1. Combined with the demonstrated nonclinical activity of NVL-655 in the periphery and in the CNS, and its selective inhibition of ALK and ALK single and compound drug-resistance mutations over the structurally-related TRK kinases, we believe there is the potential for NVL-655 to provide durable responses while minimizing adverse events and dose limiting toxicities for patients with ALK-positive cancers throughout the treatment paradigm." "With today's announcement, we've delivered on the first of the key 2024 milestones laid out in our OnTarget 2026 operating plan, an achievement made possible by the tireless dedication of our team to our mission of delivering precisely targeted therapies to patients with cancer," said James Porter, Ph.D., Chief Executive Officer at Nuvalent. "With all of our programs, our goal is to not only address the existing medical needs for later-line patients but to ultimately deliver therapies that can move up the treatment paradigm, and our multi-pronged development strategy for NVL-655 exemplifies this approach. We look forward to sharing an update from the ALKOVE-1 trial as well as more detail on our broader front-line development strategy for ALK later this year." ALKOVE-1 Phase 2 Design The Phase 2 portion of the ALKOVE-1 trial will be conducted globally across North America, Europe, Asia, and Australia. The 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. The Phase 2 cohorts are designed to evaluate NVL-655 in: TKI Pre-Treated ALK-Positive NSCLC 2 – 3 Prior TKIs: Patients with locally advanced or metastatic NSCLC harboring an ALK rearrangement, who have received 2-3 prior ALK TKIs. Up to 2 prior lines of chemotherapy and/or immunotherapy are allowed. 1 Prior 2G TKI: Patients with locally advanced or metastatic NSCLC harboring an ALK rearrangement who have received 1 prior second-generation (2G) ALK TKI (ceritinib, alectinib, or brigatinib). Up to 2 prior lines of chemotherapy and/or immunotherapy are allowed. 1 Prior 3G TKI: Patients with locally advanced or metastatic NSCLC harboring an ALK rearrangement, who have received lorlatinib (third-generation, 3G) as the only prior ALK TKI therapy. Up to one prior line of chemotherapy and/or immunotherapy received prior to lorlatinib is allowed. TKI-Naïve ALK-Positive NSCLC Patients with locally advanced or metastatic NSCLC harboring an ALK rearrangement, who are naïve to ALK TKI therapy. Up to one prior line of chemotherapy and/or immunotherapy is allowed. Other Other ALK-Positive NSCLC: Patients with locally advanced or metastatic NSCLC harboring an ALK rearrangement, not eligible for other Phase 2 cohorts. Other ALK-Positive Solid Tumors: Patients with other solid tumors harboring an ALK rearrangement or activating ALK mutation, who have received ≥1 prior systemic anticancer therapy, or for whom no satisfactory standard therapy exists. Additional details can be found on (NCT05384626). Selection of NVL-655 RP2D The selection of 150 mg QD as the RP2D for NVL-655 was supported by the FDA based on clinical data from the Phase 1 dose escalation portion of the ALKOVE-1 trial. The company believes that the preliminary Phase 1 data support the opportunity for NVL-655 as a potential best-in-class therapy that may be able to move up the treatment paradigm for patients with ALK-positive NSCLC. The selection was based on the following considerations: The dose level of 150 mg QD maintained steady state plasma levels above target efficacy thresholds (ALK wild type fusions and ALK single and compound mutations in both the periphery and in the CNS). Favorable tolerability of NVL-655 was observed at the 150 mg QD dose level, continuing to suggest the potential for a highly ALK-selective, TRK sparing safety profile. Early anti-tumor activity was observed in ALK-positive NSCLC patients across a broad range of doses, including 150 mg QD. Objective responses (RECIST 1.1) were observed in heavily pre-treated patients including patients who had received one or more second-generation TKIs (alectinib, brigatinib, or ceritinib) plus lorlatinib, patients who were lorlatinib-naïve, patients with ALK single and compound resistance mutations, and patients with CNS metastases. Preliminary Phase 1 data were presented in October 2023, and the company expects to share an update from the ALKOVE-1 trial at a medical meeting in 2024. About NVL-655 NVL-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 both 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 orphan drug designation for ALK-positive non-small cell lung cancer (NSCLC) and is currently being investigated in the ALKOVE-1 clinical trial (NCT05384626), a first-in-human Phase 1/2 clinical trial for patients with advanced ALK-positive NSCLC and other solid tumors.

Encouraging preliminary signs of activity observed in heavily pre-treated patients with ALK-positive NSCLC, including in subgroups of patients who have previously received a 2nd generation ALK TKI and lorlatinib, have brain metastases, or have single or compound ALK resistance mutations Favorable preliminary safety pro consistent with an ALK-selective, TRK sparing design Company to host a conference call today, October 13, at 8:00am EDT CAMBRIDGE, Mass., Oct. 13, 2023 /PRNewswire/ -- Nuvalent, Inc. (Nasdaq: NUVL), a clinical-stage biopharmaceutical company focused on creating precisely targeted therapies for clinically proven kinase targets in cancer, today announced updated preliminary data from the Phase 1 dose-escalation portion of its ongoing ALKOVE-1 Phase 1/2 clinical trial of NVL-655 for patients with advanced ALK-positive non-small cell lung cancer (NSCLC) and other solid tumors. These data will be presented today at the 35th AACR-NCI-EORTC (ANE) Symposium in Boston, Massachusetts. NVL-655 is a novel brain-penetrant ALK-selective tyrosine kinase inhibitor (TKI) created with the aim to simultaneously overcome the clinical challenges of emergent treatment resistance, brain metastases, and off-target central nervous system (CNS) adverse events associated with tropomyosin receptor kinase (TRK) inhibition that may limit the use of currently available ALK TKIs. "Significant advancements have been made with the development of three generations of ALK TKIs, and the five ALK inhibitors that are currently FDA-approved provide important treatment options for patients with advanced ALK fusion-positive cancers. However, some limitations remain with the available therapies, ranging from association with TRK-related neurologic adverse events that can limit adequate coverage of ALK single resistance mutations to the emergence of refractory compound mutations following sequential treatment with ALK TKIs," said presenting investigator Jessica J. Lin, M.D., Assistant Professor of Medicine, Harvard Medical School and Attending Physician, Mass General Cancer Center. "These preliminary data support the potential for NVL-655 as an ALK-selective inhibitor that may combine, for the first time, potent and selective targeting of diverse ALK fusions and secondary ALK resistance mutations, including single and compound mutations involving G1202R and I1171N, brain penetrance, and the avoidance of TRK inhibition that can be dose limiting." As of the enrollment and data cut-off date of August 8, 2023 for the preliminary data, 93 patients have been enrolled in the Phase 1 portion of the ALKOVE-1 trial across six evaluated dose levels of NVL-655 ranging from 15 mg once daily (QD) to 200 mg QD. Enrollment in the Phase 1 portion of the trial is ongoing. Preliminary activity data as of the cut-off date were available from 51 heavily pre-treated response-evaluable NSCLC patients. The objective response rate (ORR) by RECIST 1.1 was 39% (20/51) of patients treated at all doses, of which all were partial responses (4 pending confirmation). In the subset of 41 patients treated at dose levels of 50 mg QD or higher, the ORR was 44% (18/41). To evaluate key target characteristics of NVL-655, activity was examined in subgroups of the 51 response-evaluable patients treated at all doses, including: Patients with any history of CNS metastases (ORR 52%, 15/29); Patients with any ALK resistance mutation (ORR 54%, 15/28), including those with compound ALK mutations (ORR 56%, 9/16) and those with ALK G1202R single or compound mutations (ORR 71%, 12/17); The most heavily pre-treated of patients, after receiving ≥3 prior ALK TKIs including at least one 2nd generation (2G) ALK TKI (alectinib, brigatinib, or ceritinib) plus lorlatinib, and prior chemotherapy (ORR 42%, 8/19); and, Lorlatinib-naïve patients who had received at least one 2G +/- 1G ALK TKI (ORR 71%, 5/7). Preliminary pharmacokinetic (PK) analyses were available for dose levels 15 mg QD to 150 mg QD. Treatment with NVL-655 resulted in exposure above target efficacy thresholds in both the periphery and in the CNS. These preliminary PK data suggest that dose levels of 50 mg QD and above may provide increased coverage of single and compound mutations in the CNS. Preliminary pharmacodynamic analysis showed that NVL-655 induced clearance of diverse ALK resistance mutation alleles across a wide dose range. As of the cut-off date for the preliminary data, 67% (34/51) of response-evaluable patients remained on treatment with NVL-655 with duration of treatment up to 12 months (median duration of treatment of 3.4 months). All patients with tumor response continued on treatment without disease progression. NVL-655 was well-tolerated with a preliminary safety pro was favorable and consistent with its ALK-selective, TRK sparing design. "We are excited to present the first look at the safety and clinical activity of NVL-655 from our ALKOVE-1 clinical trial, which we believe supports the potential for NVL-655 to address each key area of its desired target product profile," said Christopher Turner, M.D., Chief Medical Officer of Nuvalent. "Across a wide dose range, NVL-655 demonstrated activity in a heavily pre-treated patient population that uniquely includes patients in the post-lorlatinib setting, with a favorable preliminary safety pro with its ALK-selective, TRK sparing design. Importantly, all patients with tumor response remained on treatment without disease progression as of the data cut-off date, suggesting the potential for durable responses even in this late line population." Dr. Turner continued, "Ultimately, we view the ability to keep patients on therapeutically relevant dose levels as a key indicator of the potential for NVL-655 to drive clinically meaningful durable responses when used earlier in the treatment paradigm. In earlier lines of therapy, potent activity against ALK as well as single or compound ALK resistance mutations in both the periphery and the brain has the potential to delay or prevent the emergence of both treatment resistance and CNS progression. Furthermore, selective inhibition of wild-type ALK and its resistance variants may minimize TRK-related CNS adverse events and other off-target toxicities that can be dose limiting. We believe that the preliminary characteristics of NVL-655 observed in this heavily pre-treated patient population support its opportunity as a potential best-in-class therapy that can move up the treatment paradigm to deliver deep and durable responses for patients with ALK-positive cancers." "With today's data, Nuvalent has presented preliminary proof-of-concept data for both of its novel parallel lead programs in ROS1 and ALK-positive cancers in just over 5 years since the company's inception," said James Porter, Ph.D., Chief Executive Officer at Nuvalent. "We believe this achievement is a testament to the dedication of the Nuvalent team, and to our approach of collaboration with leading physician-scientists, identification of medical needs stemming from the limitations of existing therapies, and focused application of our innovative chemistry and deep expertise in structure-based drug design to develop precisely targeted therapies according to well-defined target product pro " Dr. Porter continued, "Most importantly, we recognize that this achievement is made possible by the patients, caregivers, and investigators who are participating in the ALKOVE-1 trial and offer our sincere gratitude. We look forward to discussions with investigators and regulators on the selection of a recommended Phase 2 dose (RP2D) and the transition to the planned Phase 2 portion of ALKOVE-1 for patients with lorlatinib-naïve and lorlatinib-treated ALK-positive NSCLC. We also look forward to using the preliminary data to guide discussions with physicians regarding potential development strategies for patients with TKI-naïve ALK-positive NSCLC as we work towards our goal of bringing new treatment options to all patients with ALK-positive cancers." NVL-655 First-in-Human Preliminary Phase 1 Data NVL-655 is currently being evaluated in 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 Phase 1 dose escalation portion is enrolling ALK-positive NSCLC patients who have previously received at least one ALK TKI and patients with other ALK-positive solid tumors who have been previously treated with at least one prior systemic anticancer therapy. The primary objectives are to determine the RP2D and if applicable, the maximum tolerated dose (MTD) of NVL-655 in patients with ALK-positive solid tumors. Additional objectives include characterization of the overall safety, tolerability, and pharmacokinetic profile, and evaluation of the preliminary anti-tumor activity and intracranial activity of NVL-655. As of the enrollment and data cut-off date of August 8, 2023 for the preliminary data, 93 patients were enrolled in the Phase 1 portion of the ALKOVE-1 trial, of which 91 patients had ALK-positive NSCLC and 58% (54/93) had a history of CNS metastases. The patient population was heavily pre-treated: 100% (93/93) had received a 2G ALK TKI or lorlatinib; 77% (72/93) had received two or more ALK TKIs, including a 2G ALK TKI and lorlatinib; 44% (41/93) had received three or more ALK TKIs, including a 2G ALK TKI and lorlatinib; and, 46% (43/93) had an identified secondary ALK mutation, including 26% (24/93) with any compound ALK mutation. Preliminary Activity Analysis As of the cut-off date for the preliminary data, patients were treated in six NVL-655 dose cohorts of 15 mg, 25 mg, 50 mg, 100 mg, 150 mg, and 200 mg QD. Fifty-one patients with NSCLC were response-evaluable by investigator assessment with duration of treatment up to 12 months (median duration of treatment of 3.4 months). Key findings include early anti-tumor activity in ALK-positive NSCLC patients, including partial responses (RECIST 1.1) in: Heavily pre-treated patients: An ORR of 39% (20/51) was observed in response-evaluable patients, and all patients with tumor response continued on treatment without disease progression as of the data cut-off date. For dose levels of 50 mg or greater, which may provide increased coverage of single and compound mutations in the CNS, an ORR of 44% (18/41) was observed. In patients who have likely exhausted all available treatment options (≥3 prior ALK TKIs including a 2G ALK TKI and lorlatinib), the observed ORR was 40% (10/25) regardless of prior chemotherapy and 42% (8/19) with prior chemotherapy. Patients with ALK single or compound resistance mutations: An ORR of 54% (15/28) was observed in patients with any ALK resistance mutation, including an ORR of 56% (9/16) in patients with compound ALK mutations, and an ORR of 71% (12/17) in patients with ALK G1202R single or compound mutations. Patients with CNS metastases: An ORR of 52% (15/29) was observed in patients with any history of CNS metastases. All patients with tumor response who had a history of CNS disease continued on treatment without CNS progression. Lorlatinib-naïve patients: Of patients who received at least one 2G +/- 1G ALK TKI and had not previously received lorlatinib, 5 of 7 (71%) responded. Preliminary Safety, Pharmacokinetic, and Pharmacodynamic Analysis A favorable preliminary safety pro observed with NVL-655 treatment in the 93 patients enrolled across the dose-escalation portion of ALKOVE-1, consistent with an ALK-selective, TRK-sparing design. Most treatment-related adverse events (TRAEs) were low-grade and manageable, with the highest incidence of TRAEs being ALT increase (19%, 18/93 any grade; 6%, 6/93 ≥ Grade 3), AST increase (18%, 17/93 any grade; 4%, 4/93 ≥ Grade 3), and nausea (10%, 9/93 of which all were Grade 1 or 2). TRAEs requiring dose modification were infrequent, with 2% (2/93) discontinuations and 5% (5/93) dose reductions. There was one dose-limiting toxicity of transient asymptomatic Grade 4 CPK increase at the 200 mg QD dose level. An MTD was not reached, and the preliminary overall safety pro consistent with avoidance of TRK-related neurotoxicities. The observed favorable preliminary safety pro for achievement of NVL-655 exposure levels above target CNS efficacy thresholds for ALK, ALK single and compound G1202R mutations, and other recalcitrant ALK single mutations such as I1171N. Favorable PK and low intra-cohort patient PK variability were observed, with dose-proportional exposure and a half-life that is supportive of once daily dosing. This preliminary PK data suggest that dose levels of 50 mg QD or greater may provide increased coverage of single and compound mutations in the CNS. Preliminary pharmacodynamic findings by centrally confirmed ctDNA analysis showed that treatment with NVL-655 induced clearance of diverse ALK resistance mutation alleles across a wide dose range. Notably, 100% clearance was observed in 14 of 16 patients with centrally confirmed single or compound ALK G1202R or I1171X (X = N or T) mutations, of which 13 had received prior lorlatinib. Combined with the favorable preliminary activity observed as of the data cut-off date, these data suggest that NVL-655 has opportunity as a potential best-in-class therapy that may be able to move up the treatment paradigm for patients with ALK-positive NSCLC. The ALKOVE-1 clinical trial is continuing to enroll patients in the Phase 1 portion of the trial and is focused on further characterizing the safety, PK, and pharmacodynamic pro determining the RP2D, and if applicable, the MTD of NVL-655. Upon RP2D selection, the trial is designed to transition directly into the Phase 2 portion, which will evaluate the safety and activity of NVL-655 in several expansion cohorts of patients defined based on the number and type of prior anti-cancer therapies they have received. The Phase 2 cohorts are intended to support potential registration in patients with ALK-positive NSCLC who are both lorlatinib-naïve and lorlatinib-treated. In addition to the planned Phase 2 cohorts, Nuvalent intends to use these preliminary data in patients with heavily pre-treated ALK-positive NSCLC to guide discussions with physicians that will inform development strategies in TKI-naïve ALK-positive NSCLC.

About NVL-655 NVL-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 the solvent front G1202R mutation or compound mutations G1202R / L1196M ("GRLM"), G1202R / G1269A ("GRGA"), or G1202R/L1198F ("GRLF"). NVL-655 has been designed for CNS penetrance to improve treatment options for patients with brain metastases. NVL-655 has been observed in preclinical studies to selectively inhibit wild-type ALK and its resistance variants over the structurally related tropomyosin receptor kinase (TRK) family to potentially avoid TRK-related CNS adverse events seen with dual TRK/ALK inhibitors and drive more durable responses for patients. NVL-655 is currently being investigated in the ALKOVE-1 clinical trial (NCT05384626), a first-in-human Phase 1/2 clinical trial for patients with advanced ALK-positive non-small cell lung cancer (NSCLC) and other solid tumors.
