The complete, corrected release follows, with additional details at the end: Nuvation Bio Announces IBTROZI® (Taletrectinib) Showed Highly Durable Responses in Longer-Term Follow-up Data from Pivotal Studies Presented at AACR 2026Analysis of longer-term pooled data from TRUST-I and TRUST-II demonstrated nearly 50 months median duration of response and 46.1 months median progression-free survival in TKI-naïve patients IBTROZI also demonstrated a high overall response rate in TKI-naïve patients at 89.8% Long-term pooled data highlighted in oral and poster presentations at AACR, and TRUST-I data simultaneously published in the Journal of Clinical Oncology, reinforce IBTROZI's manageable safety profile, with low rates of neurologic side effects and no new safety signals IBTROZI demonstrated robust CNS activity, with an intracranial response rate of 76.5% in TKI-naïve patients and 65.6% in TKI-pretreated patients with brain metastases Preclinical data presented at AACR showed taletrectinib's potential for suppressing TRKB-mediated lung cancer cell migration NEW YORK, April 21, 2026 /PRNewswire/ -- Nuvation Bio Inc. (NYSE: NUVB), a global oncology company focused on tackling some of the toughest challenges in cancer treatment, today announced results from a pooled analysis of long-term follow-up data from the pivotal TRUST-I and TRUST-II trials for IBTROZI® (taletrectinib) in patients with advanced ROS1-positive (ROS1+) non-small cell lung cancer (NSCLC). The updated efficacy and safety results for both TKI-naïve and TKI-pretreated patients were presented at the American Association for Cancer Research (AACR) Annual Meeting 2026 in oral and poster presentations. The long-term pooled results in TKI-naïve patients demonstrated a confirmed objective response rate (cORR) of 89.8%, a median duration of response (mDOR) of 49.7 months and a median progression-free survival (mPFS) of 46.1 months. Updated results from the TRUST-I study were also simultaneously published in the Journal of Clinical Oncology, demonstrating robust ORR, mDOR and mPFS in TKI-naïve patients, with a median follow up of 51 months.
"Achieving durable responses is a primary goal in treating ROS1-positive lung cancer. These extensive follow-up data with this next-generation ROS1 inhibitor show high rates of responses that last more than four years for many patients, and a median progression-free survival that's nearly just as long," stated Lyudmila Bazhenova, M.D., Medical Oncologist at UC San Diego Health, Professor of Medicine at University of California San Diego School of Medicine and investigator for the TRUST-II study. "Critically, the data demonstrated robust intracranial activity without the significant central nervous system toxicities that often limit the long-term use of other brain-penetrant therapies, and a favorable safety profile that allowed patients to stay on treatment and continue to benefit." The new pooled analysis presented at AACR demonstrated robust efficacy with IBTROZI for both TKI-naïve and TKI-pretreated patients in TRUST-I and TRUST-II.
A pooled safety analysis demonstrated a favorable and manageable safety profile for IBTROZI, consistent with its prescribing information. Adverse events (AEs) of clinical interest (diarrhea, nausea, vomiting and dizziness) were generally low-grade and resolved quickly. Treatment discontinuations due to treatment-emergent AEs (TEAEs) were low (8.5%). No new safety signals were identified with the longer follow-up. In another poster session at AACR, new preclinical data showed that taletrectinib inhibited the migration of lung cancer cells, suggesting the ability of taletrectinib to reduce the invasive capacity of lung cancer cells based on its tropomyosin receptor kinase B (TRKB) inhibition profile. In mechanistic studies, taletrectinib reduced the expression of key markers associated with the epithelial to mesenchymal transition pathway. The data also suggested that TRKB-sparing agents may not reduce the migration of TRKB expressing lung cancer cells and may lack the potential CNS-protective effects of TRKB inhibition. "Our objective was to redefine the standard of care for advanced ROS1-positive NSCLC, and we believe IBTROZI is delivering on that promise," said David Hung, M.D., Founder, President and Chief Executive Officer of Nuvation Bio. "In these updated long-term clinical data presented at AACR and published in the prestigious Journal of Clinical Oncology, IBTROZI demonstrated remarkable durability, underscored by the long mDOR and mPFS seen in ROS1+ TKI-naïve patients. And new preclinical data suggest that taletrectinib inhibits critical pathways that can lead to metastasis. When you combine these benefits with its favorable safety profile, you have a treatment that we believe addresses the disease from all angles." Nuvation Bio announced in June 2025 that the U.S. Food and Drug Administration (FDA) approved IBTROZI for the treatment of adult patients with locally advanced or metastatic ROS1+ NSCLC. IBTROZI is also approved for patients with advanced ROS1+ NSCLC in Japan, where it is marketed by Nippon Kayaku, and in China, where it is marketed by Innovent Biologics under the brand name DOVBLERON®. Additionally, Nuvation Bio, along with its partner Eisai, announced in March 2026 that the Marketing Authorisation Application (MAA) for taletrectinib was validated by the European Medicines Agency and accepted for full approval consideration with a standard review timeline.

About ROS1+ NSCLC About IBTROZI About the TRUST Clinical Program U.S. Indication IMPORTANT SAFETY INFORMATION FOR IBTROZI® (taletrectinib) WARNINGS AND PRECAUTIONS Hepatotoxicity: Hepatotoxicity, including drug-induced liver injury and fatal adverse reactions, can occur. 88% of patients experienced increased AST, including 10% Grade 3/4. 85% of patients experienced increased ALT, including 13% Grade 3/4. Fatal liver events occurred in 0.6% of patients. Median time to first onset of AST or ALT elevation was 15 days (range: 3 days to 20.8 months). Increased AST or ALT each led to dose interruption in 7% of patients and dose reduction in 5% and 9% of patients, respectively. Permanent discontinuation was caused by increased AST, ALT, or bilirubin each in 0.3% and by hepatotoxicity in 0.6% of patients. Concurrent elevations in AST or ALT ≥3 times the ULN and total bilirubin ≥2 times the ULN, with normal alkaline phosphatase, occurred in 0.6% of patients. Interstitial Lung Disease (ILD)/Pneumonitis: Severe, life-threatening, or fatal ILD or pneumonitis can occur. ILD/pneumonitis occurred in 2.3% of patients, including 1.1% Grade 3/4. One fatal ILD case occurred at the 400 mg daily dose. Median time to first onset of ILD/pneumonitis was 3.8 months (range: 12 days to 11.8 months). ILD/pneumonitis led to dose interruption in 1.1% of patients, dose reduction in 0.6% of patients, and permanent discontinuation in 0.6% of patients. QTc Interval Prolongation: QTc interval prolongation can occur, which can increase the risk for ventricular tachyarrhythmias (e.g., torsades de pointes) or sudden death. IBTROZI prolongs the QTc interval in a concentration-dependent manner. In patients who received IBTROZI and underwent at least one post baseline ECG, QTcF increase of >60 msec compared to baseline and QTcF >500 msec occurred in 13% and 2.6% of patients, respectively. 3.4% of patients experienced Grade ≥3. Median time from first dose of IBTROZI to onset of ECG QT prolongation was 22 days (range: 1 day to 38.7 months). Dose interruption and dose reduction each occurred in 2.8% of patients. Significant QTc interval prolongation may occur when IBTROZI is taken with food, strong and moderate CYP3A inhibitors, and/or drugs with a known potential to prolong QTc. Administer IBTROZI on an empty stomach. Avoid concomitant use with strong and moderate CYP3A inhibitors and/or drugs with a known potential to prolong QTc. Hyperuricemia: Hyperuricemia can occur and was reported in 14% of patients, with 16% of these requiring urate-lowering medication without pre-existing gout or hyperuricemia. 0.3% of patients experienced Grade ≥3. Median time to first onset was 2.1 months (range: 7 days to 35.8 months). Dose interruption occurred in 0.3% of patients. Myalgia with Creatine Phosphokinase (CPK) Elevation: Myalgia with or without CPK elevation can occur. Myalgia occurred in 10% of patients. Median time to first onset was 11 days (range: 2 days to 10 months). Concurrent myalgia with increased CPK within a 7-day time period occurred in 0.9% of patients. Dose interruption occurred in 0.3% of patients with myalgia and concurrent CPK elevation. Skeletal Fractures: IBTROZI can increase the risk of fractures. ROS1 inhibitors as a class have been associated with skeletal fractures. 3.4% of patients experienced fractures, including 1.4% Grade 3. Some fractures occurred in the setting of a fall or other predisposing factors. Median time to first onset of fracture was 10.7 months (range: 26 days to 29.1 months). Dose interruption occurred in 0.3% of patients. Embryo-Fetal Toxicity: Based on literature, animal studies, and its mechanism of action, IBTROZI can cause fetal harm when administered to a pregnant woman. ADVERSE REACTIONS Among patients who received IBTROZI, the most frequently reported adverse reactions (≥20%) were diarrhea (64%), nausea (47%), vomiting (43%), dizziness (22%), rash (22%), constipation (21%), and fatigue (20%). The most frequently reported Grade 3/4 laboratory abnormalities (≥5%) were increased ALT (13%), increased AST (10%), decreased neutrophils (5%), and increased creatine phosphokinase (5%).
