Achieved $45.0 million in third quarter 2026 total revenue, including $27.5 million in net product revenue for IBTROZI ® (taletrectinib) IBTROZI continues to be the most prescribed ROS1 TKI and established as the ROS1 market leader in new patient starts and total active patients for both first-line and all lines of therapy combined, based on IQVIA claims data FDA approved a supplemental New Drug Application (sNDA) for IBTROZI, updating label to reflect median duration of response of 49.7 months in TKI-naïve ROS1+ NSCLC patients in TRUST-I FDA granted Fast Track Designation to safusidenib for the treatment of IDH1-mutant glioma Cash, cash equivalents, and marketable securities of $663.4 million as of September 30, 2026 Company to host a conference call today at 4:30 p.m. ET NEW YORK , Nov. 4, 2026 /PRNewswire/ -- Nuvation Bio Inc. (NYSE: NUVB), a global oncology company focused on tackling some of the toughest challenges in cancer treatment, today reported financial results for the third quarter ended September 30, 2026, and provided a business update. "Just over one year after launch, IBTROZI was established as the market leader in advanced ROS1+ NSCLC, for both new patient starts and active patients across all lines of therapy combined, based on IQVIA claims data," said David Hung, M.D., Founder, President, and Chief Executive Officer of Nuvation Bio. "Our rapid rise to market leadership reflects growing provider confidence in IBTROZI's durability of more than four years in TKI-naïve patients and a generally favorable safety pro helps patients stay on therapy. With our recent sNDA approval, the label now reflects IBTROZI's 49.7-month median duration of response in TRUST-I, giving physicians clear data to guide treatment decisions and supporting its use early in a patient's care." Dr. Hung continued, "The FDA's recent Fast Track Designation for safusidenib underscores both the significant unmet need in IDH1 -mutant glioma and the potential of this investigational medicine to address it. We are moving quickly to advance our comprehensive development program, with two Phase 2 and two pivotal Phase 3 studies spanning multiple IDH1 -mutant glioma subpopulations, designed to reach a broad spectrum of patients with this disease." Third Quarter 2026 and Recent Highlights: IBTROZI ® (taletrectinib), ROS1 inhibitor: Advanced ROS1+ NSCLC In the third quarter of 2026, Nuvation Bio reported $27.5 million in net product revenue for IBTROZI, an 18% quarter-over-quarter growth that reflects the continued adoption and durability of treatment. New patient starts in Q3 remained consistent with the prior quarter at approximately 160 patients, despite an approximately 15% quarter-over-quarter decline in new patient starts across the overall ROS1-positive non-small cell lung cancer (ROS1+ NSCLC) tyrosine kinase inhibitor (TKI) market, based on IQVIA claims data. Of these starts, 65% were TKI-naïve, demonstrating that IBTROZI is becoming standard of care in the first-line treatment setting. The remaining starts, in TKI-pretreated patients, show that physicians also continue to prescribe IBTROZI in later lines. In September 2026, Nuvation Bio announced that the U.S. Food and Drug Administration (FDA) approved a supplemental New Drug Application (sNDA) for IBTROZI, four months ahead of the January 4, 2027, target action date. The updated label reflects a median duration of response (mDOR) of 49.7 months in TKI-naïve patients, based on a median patient follow-up of 51 months from the pivotal TRUST-I study. No changes were made to the safety sections of the label. In September 2026, Nuvation Bio announced new subgroup analyses from the pivotal TRUST-I and TRUST-II studies, presented at the IASLC 2026 World Conference on Lung Cancer (WCLC), showing consistent efficacy across key patient subgroups. In October 2026, Nuvation Bio presented updated TRUST-II efficacy and safety data for IBTROZI in patients previously treated with entrectinib at the European Society for Medical Oncology (ESMO) Congress 2026 in Madrid, Spain. Safusidenib, mIDH1 inhibitor: IDH1-mutant glioma In August 2026, Nuvation Bio announced that the FDA granted Fast Track Designation to safusidenib for the treatment of IDH1 -mutant glioma. The designation was supported by favorable data from the safusidenib clinical program, including updated long-term results from the Phase 2 J201 study, and provides for more frequent interactions with the FDA throughout development. In July 2026, Nuvation Bio announced updated long-term data and new clinical studies for safusidenib: Updated Phase 2 J201 data in patients with chemotherapy- and radiotherapy-naïve grade 2 IDH1 -mutant glioma showed a centrally assessed ORR of 51.9% at a median follow-up of 38.8 months. Median progression-free survival (PFS) was not reached; the 36-month PFS rate was 79.1%. No new safety signals were identified. Initiation of a pivotal Phase 3 study (G307) in patients with grade 2 IDH1 -mutant glioma outside the U.S. Initiation of a Phase 2 study (G209) in patients with IDH1 -mutant glioma that has progressed after prior treatment with vorasidenib in the U.S. In October 2026, Nuvation Bio announced expansion of the pivotal Phase 3 SIGMA study of investigational safusidenib to include study sites in the United Kingdom, France, Sweden, Germany, Italy and Spain. These additional countries extend SIGMA's global footprint beyond the U.S., Australia, China, Canada and Japan, where the study is currently enrolling or will soon begin enrolling. In November 2026, Nuvation Bio announced four posters to be presented at the 2026 Society for Neuro-Oncology Annual Meeting taking place November 12–15, 2026, in Philadelphia, PA, including additional updated data from the Phase 2 J201 study beyond the topline results shared in July 2026. Drug-drug conjugate (DDC) platform: Solid tumors Nuvation Bio continues to explore new preclinical candidates for this novel modality and aims to provide further updates by year-end 2026. Corporate Update: In July 2026, Nuvation Bio announced the full exercise of the greenshoe option in its offering of 0.75% Convertible Senior Notes due 2032. The underwriters purchased an additional $37.5 million aggregate principal amount of notes, bringing the aggregate principal amount sold in the offering to $287.5 million, with net proceeds of approximately $279.1 million after deducting underwriting discounts and commissions and offering expenses. Third Quarter 2026 Financial Results As of September 30, 2026, Nuvation Bio had cash, cash equivalents, and marketable securities of $663.4 million, which includes an additional $36.5 million in net proceeds secured in July 2026 from exercise of the convertible senior notes overallotment option. Product Revenue, Net To date, Nuvation Bio's product revenue comes exclusively from U.S. sales of IBTROZI, which Nuvation Bio began distributing to its U.S. customers in June 2025. Net product revenue from U.S. sales of IBTROZI was approximately $27.5 million for the three months ended September 30, 2026. Collaboration and License Agreements Revenue For the three months ended September 30, 2026, collaboration and license agreements revenue was $17.5 million, compared to $5.4 million for the three months ended September 30, 2025. The increase is due to a $7.6 million increase in product supply revenue, a $5.0 million sales milestone received from Innovent, and a $2.4 million increase in royalty revenue, offset by a $2.9 million decrease in research and development service revenue under the collaboration agreements with Innovent and Nippon Kayaku. Taletrectinib was included in China's National Reimbursement Drug List effective January 1, 2026. Royalty revenue for the quarter from collaboration agreements for China and Japan was $2.7 million. Research and Development Expenses For the three months ended September 30, 2026, research and development expenses were $32.7 million, compared to $28.8 million for the three months ended September 30, 2025. The increase was primarily due to a $3.3 million increase in third-party costs related to clinical trial expense and a $0.5 million increase in personnel costs driven by the increase in headcount and stock-based compensation. Selling, General and Administrative Expenses For the three months ended September 30, 2026, selling, general and administrative expenses were $42.6 million, compared to $37.4 million for the three months ended September 30, 2025. The increase was due to a $2.5 million increase in salaries and other benefits driven by the increase in headcount and stock-based compensation, a $1.8 million increase in sales and marketing expenses and a $1.6 million increase in miscellaneous expense, offset by a $0.7 million decrease in legal fees. Net Loss For the three months ended September 30, 2026, Nuvation Bio reported a net loss of $41.9 million, or $(0.12) per share on a basic and diluted basis. The net loss for the comparable period in 2025 was $55.8 million, or $(0.16) per share on a basic and diluted basis.

About ROS1+ NSCLC Each year, more than one million people globally are diagnosed with non-small cell lung cancer (NSCLC), the most common form of lung cancer. It is estimated that approximately 2% of patients with NSCLC have ROS1+ disease. About 35% of patients newly diagnosed with metastatic ROS1+ NSCLC have tumors that have spread to their brain. The brain is also the most common site of disease progression, with about 50% of previously treated patients developing central nervous system (CNS) metastases. About IBTROZI IBTROZI is an oral, potent, CNS-active, selective, next-generation ROS1 inhibitor therapy. In June 2025, following Priority Review and Breakthrough Therapy designations for both TKI-naive and TKI-pretreated disease, the U.S. Food and Drug Administration (FDA) approved taletrectinib for the treatment of adult patients with locally advanced or metastatic ROS1+ NSCLC. Learn more about taletrectinib in the U.S. at IBTROZI.com . About the TRUST Clinical Program The TRUST clinical program comprises three registrational studies evaluating the safety and efficacy of IBTROZI. TRUST-I ( NCT04395677 ) and TRUST-II ( NCT04919811 ) are Phase 2 single-arm studies evaluating IBTROZI for the treatment of adults with advanced ROS1+ NSCLC in China (N=173) and globally (N=189), respectively. The primary endpoint of both studies is confirmed objective response rate (cORR) as assessed by an independent review committee. TRUST-IV ( NCT07154706 ) is a Phase 3 placebo-controlled study evaluating IBTROZI for the adjuvant treatment of adults with resected early-stage ROS1+ NSCLC. The study will enroll approximately 180 patients in the U.S., Canada, Europe, Japan and China. The primary endpoint is disease-free survival as determined by investigator, and the primary completion date is estimated to be in 2030. Nuvation Bio is also sponsoring TRUST-III ( NCT06564324 ), a confirmatory randomized Phase 3 study evaluating IBTROZI versus crizotinib in 194 patients in China with advanced ROS1+ NSCLC who have not previously received ROS1 TKIs. Indication IBTROZI is indicated for the treatment of adult patients with locally advanced or metastatic ROS1+ non-small cell lung cancer (NSCLC). 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%). DRUG INTERACTIONS Strong and Moderate CYP3A Inhibitors/CYP3A Inducers and Drugs that Prolong the QTc Interval: Avoid concomitant use. Gastric Acid Reducing Agents: Avoid concomitant use with PPIs and H2 receptor antagonists. If an acid-reducing agent cannot be avoided, administer locally acting antacids at least 2 hours before or 2 hours after taking IBTROZI. OTHER CONSIDERATIONS Pregnancy: Please see important information in Warnings and Precautions under Embryo-Fetal Toxicity. Lactation: Advise women not to breastfeed during treatment and for 3 weeks after the last dose. Effect on Fertility: Based on findings in animals, IBTROZI may impair fertility in males and females. The effects on animal fertility were reversible. Pediatric Use: The safety and effectiveness of IBTROZI in pediatric patients has not been established. Photosensitivity: IBTROZI can cause photosensitivity. Advise patients to minimize sun exposure and to use sun protection, including broad-spectrum sunscreen, during treatment and for at least 5 days after discontinuation. Please see accompanying full Prescribing Information . About IDH1 -mutant Glioma Gliomas are the most common type of brain cancer in adults worldwide. In the U.S., nearly 2,500 people are diagnosed with IDH -mutant gliomas each year, of which more than 95% harbor a mutation in the IDH1 gene. Most patients are diagnosed in their 30s and 40s. While patients with IDH1 mutations generally have longer survival times than those with wild-type IDH1 , gliomas are not currently curable and prognosis worsens for those with high-risk features, including high-grade tumors. About Safusidenib Safusidenib is an investigational, oral, brain-penetrant, selective inhibitor of mutant IDH1. It is being studied in patient populations with significant unmet medical need, including settings where there are limited or no approved targeted treatment options. In Phase 1 and Phase 2 clinical studies, safusidenib demonstrated encouraging clinical activity, including delayed disease progression and durable responses across a range of tumor grades and risk groups, with a favorable risk-benefit profile. These early findings support further investigation of safusidenib in the currently enrolling Phase 3 SIGMA study, as well as in the Phase 3 G307 study in regions where vorasidenib is not yet approved or accessible and the Phase 2 G209 study in patients whose cancer has progressed on vorasidenib. In August 2026, the FDA granted Fast Track Designation to safusidenib for the treatment of IDH1 -mutant glioma. About the SIGMA (G203) Study SIGMA is a pivotal Phase 3 study that will evaluate safusidenib compared to placebo as a maintenance therapy after standard-of-care in IDH1 -mutant astrocytoma with high-risk features. The pivotal portion of the study will enroll approximately 300 patients. A separate, exploratory, non-pivotal cohort will evaluate safusidenib in participants with grade 3 IDH1 -mutant oligodendroglioma who have not yet received chemotherapy or radiotherapy. The primary endpoint is objective response rate. This cohort is expected to enroll approximately 40 patients.
