Insights

The pooled data from TRUST-I and TRUST-II studies demonstrate taletrectinib's impressive efficacy in ROS1+ NSCLC patients. With a 89% tumor shrinkage rate in TKI-naïve patients and 56% in TKI-pretreated patients, these results are highly encouraging. The median DOR of 44 months and PFS of 46 months in TKI-naïve patients are particularly noteworthy, suggesting durable responses and long-term disease control. The drug's efficacy against brain metastases (77% intracranial cORR in TKI-naïve) addresses a critical unmet need in NSCLC treatment. Moreover, its activity against the G2032R mutation (62% cORR) indicates potential in overcoming resistance mechanisms. These results position taletrectinib as a promising option in the ROS1+ NSCLC treatment landscape.

Taletrectinib's safety profile is a key highlight of this data. The low incidence of neurologic TEAEs and treatment discontinuations (7%) suggest better tolerability compared to existing ROS1 inhibitors. While liver enzyme elevations were common, severe cases (≥ Grade 3) were relatively infrequent. The 29% dose reduction rate due to TEAEs indicates manageable toxicity. This favorable safety profile, combined with its efficacy, could potentially allow for longer treatment duration, contributing to improved outcomes. The data support taletrectinib's potential as a best-in-class ROS1 TKI, offering a balance of efficacy and tolerability that could significantly impact treatment strategies for ROS1+ NSCLC patients.

The positive pooled data significantly strengthen Nuvation Bio's position in the competitive oncology market. With plans to submit an NDA in Q4 2024 and potential U.S. launch in 2025, taletrectinib could become a major revenue driver for the company. The global NSCLC market, valued at $19.3 billion in 2023, is projected to grow substantially. While ROS1+ cases represent a niche (1-2% of NSCLC), taletrectinib's potential best-in-class profile could capture a significant market share. Investors should note the planned transition to a commercial-stage organization, which could impact financial metrics and valuation. However, the path to commercialization will require significant investment in marketing and distribution infrastructure. The stock may see increased interest as the NDA submission approaches, but investors should remain cautious of regulatory risks and potential competition in this space.

Tumors shrank in 89% of taletrectinib-treated patients with advanced ROS1-positive (ROS1+) non-small cell lung cancer (NSCLC) who were tyrosine kinase inhibitor (TKI)-naïve and 56% of those who were TKI-pretreated in the study

Taletrectinib demonstrated durable responses and prolonged progression-free survival (PFS) with long-term follow up; median duration of response (DOR) and median PFS in TKI-naïve patients were 44 months and 46 months, respectively

Taletrectinib demonstrated a favorable safety and tolerability profile, including low incidence of neurologic treatment-emergent adverse events (TEAEs) and low rate of treatment discontinuation

Nuvation Bio plans to submit a New Drug Application (NDA) for taletrectinib to the U.S. Food and Drug Administration (FDA) in the fourth quarter of 2024

NEW YORK--(BUSINESS WIRE)-- Nuvation Bio Inc. (NYSE: NUVB), a late clinical-stage, global biopharmaceutical company tackling some of the greatest unmet needs in oncology, today announced positive pooled data from the pivotal Phase 2 TRUST-I and TRUST-II studies evaluating taletrectinib, an investigational next-generation ROS1 TKI. The findings will be highlighted in a poster presentation on September 14, 2024, at the European Society of Medical Oncology (ESMO) Congress 2024 in Barcelona, Spain.

Maurice Perol, M.D., TRUST-II study investigator and Head of Thoracic Oncology at Léon Bérard Cancer Center, commented on the results: “The unmet need for more effective and tolerable treatments for patients with advanced ROS1-positive NSCLC remains critical. The pooled analysis from the TRUST-I and TRUST-II studies reinforces taletrectinib’s potential to offer clinically meaningful advancements in efficacy combined with a favorable safety profile, including reported median duration of response of 44 months and progression-free survival of 46 months in patients who were TKI-naïve.”

“We are excited to present compelling pooled data from the TRUST-I and TRUST-II studies at ESMO, which highlight taletrectinib’s durable response, prolonged disease control, and favorable safety profile. We believe these results position taletrectinib as a potential best-in-class treatment option for people living with advanced ROS1-positive NSCLC,” said David Hung, M.D., Founder, President, and Chief Executive Officer of Nuvation Bio. “These pivotal data will support our planned NDA submission in the fourth quarter of 2024 and, assuming regulatory approval, will enable us to launch taletrectinib in the U.S. in 2025. We are committed to making a positive impact on the lung cancer community and look forward to sharing updates as we continue toward becoming a commercial stage organization.”

Summary of Pivotal Pooled Data

The pooled efficacy and safety data from the TRUST-I and TRUST-II studies presented at ESMO are as of June 7, 2024; both studies remain ongoing. The ESMO data set includes 337 patients with advanced ROS1+ NSCLC who received 600mg of taletrectinib orally once daily in 21-day cycles.

The primary endpoint of these registrational studies is confirmed objective response rate (cORR) as assessed by an independent review committee (IRC). Key secondary endpoints include intracranial cORR, DOR, PFS, and safety.

Significant Tumor Shrinkage and Durability

The pooled efficacy analyses included 160 patients with advanced ROS1+ NSCLC who had not previously been treated with a ROS1 TKI (TKI-naïve) and 113 patients who had previously been treated with crizotinib or entrectinib (TKI-pretreated).

Among these two populations, 94% of patients had stage IV NSCLC. In addition, 20% of TKI-naïve and 37% of TKI-pretreated patients received prior chemotherapy, while 23% of TKI-naïve and 49% of TKI-pretreated patients had brain metastases at baseline.

The efficacy results, independently assessed by an IRC, showed:

In TKI-naïve patients (n=160):

  • Tumors shrank in 89% of taletrectinib-treated patients (cORR).
  • Measurable brain metastases shrank in 77% (13/17) of taletrectinib-treated patients (intracranial cORR).
  • After median follow-up of 21 months, the median DOR and the median PFS were 44 months and 46 months, respectively.

In TKI-pretreated patients (n=113):

  • Tumors shrank in 56% of taletrectinib-treated patients (cORR).
  • Measurable brain metastases shrank in 66% (21/32) of taletrectinib-treated patients (intracranial cORR).
  • Tumors shrank in 62% (8/13) of taletrectinib-treated patients with G2032R mutations (cORR).
  • After median follow-up of 21 months, the median DOR and the median PFS were 17 months and 10 months, respectively.

Favorable and Consistent Safety Profile Across Studies

The pooled safety analysis included 337 patients with advanced ROS1+ NSCLC. The results demonstrated a favorable safety and tolerability profile, with a low incidence and a limited spectrum of neurologic TEAEs and a low rate of treatment discontinuation.

The most frequent TEAEs were increased aspartate aminotransferase (72%; 8% ≥ Grade 3), alanine aminotransferase (68%; 10% ≥ Grade 3), diarrhea (63%; 2% ≥ Grade 3), and nausea (47%; 2% ≥ Grade 3).

The incidence of neurologic TEAEs was low; the most common were dizziness (21%) and dysgeusia (15%), most of which were Grade 1. The rate of treatment discontinuation due to TEAEs was 7% and the rate of dose reduction due to TEAEs was 29%.

Data Presentation and Availability

The data in the ESMO poster from the Response Evaluable Population, which includes all patients with measurable disease who received at least one dose of taletrectinib as of June 7, 2024, form the primary efficacy analysis that will support Nuvation Bio’s planned NDA submission in the United States.

The data in the ESMO abstract represent clinical results from patients enrolled at least 14 months before the data cutoff of March 29, 2024.
