Nuvation Bio Announces National Comprehensive Cancer Network® Adds Taletrectinib (IBTROZI™) as Preferred Option to Clinical Practice Guidelines in Oncology for Advanced ROS1+ Non-Small Cell Lung Cancers

Guidelines include the next-generation targeted therapy with Preferred status across all lines of therapy in advanced setting, including patients with brain metastases and acquired resistance mutations

Nuvation Bio Inc. (NYSE:NUVB), a global oncology company focused on tackling some of the toughest challenges in cancer treatment, today announced that taletrectinib (IBTROZI™) has been added as a Preferred Agent in the latest National Comprehensive Cancer Network^® Clinical Practice Guidelines (NCCN Guidelines^®) in Oncology for Non-Small Cell Lung Cancers (NSCLC), updated on June 20. Specifically, the NCCN Guidelines^® now include taletrectinib (IBTROZI) as a Preferred Agent for both first-line and subsequent therapy for ROS1-positive NSCLC, including specific recommendations for those with brain metastases and resistance mutations.

"We are very pleased the NCCN acted with such urgency to review and update the NCCN Guidelines to include taletrectinib (IBTROZI) as a preferred option for advanced ROS1-positive NSCLC across treatment lines, with particular recognition of benefit for patients with brain metastases and those with acquired resistance after first-line therapy," said David Hung, M.D., Founder, President and Chief Executive Officer of Nuvation Bio. "These updates address critical needs for patients across their treatment journeys, especially with the prevalence of CNS involvement for those living with ROS1+ NSCLC. Additionally, this version builds further upon a previous guideline update that importantly highlights preferred utilization of ROS1-targeted agents instead of immunotherapy and chemotherapy for these patients."

The U.S. Food and Drug Administration (FDA) approved taletrectinib (IBTROZI) on June 11 for the treatment of adult patients with locally advanced or metastatic ROS1+ NSCLC. Taletrectinib (IBTROZI) is a highly selective, next-generation oral ROS1 tyrosine kinase inhibitor (TKI) designed to address some of the outstanding challenges of treating the disease.

ROS1+ NSCLC is a rare and aggressive form of lung cancer, accounting for approximately 2% of new NSCLC cases, or about 3,000 new diagnoses of advanced disease annually in the U.S. The median age at diagnosis for patients with this type of lung cancer is approximately 50 years old, and the disease is more likely to occur in people who have never smoked. Brain metastases are common and a leading cause of disease progression and mortality in this population.

The NCCN is a not-for-profit alliance of 33 leading cancer centers devoted to patient care, research, and education. NCCN is dedicated to defining and advancing quality, effective, equitable, and accessible cancer care and prevention so all people can live better lives. NCCN makes no warranties of any kind whatsoever regarding their content, use or application and disclaims any responsibility for their application or use in any way.

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 CNS metastases. Despite recent progress for patients with ROS1+ NSCLC, there remains a need for more effective and tolerable treatment options.

About IBTROZI

IBTROZI is an oral, potent, central nervous system-active, selective, next-generation ROS1 inhibitor therapy approved for the treatment of adult patients with advanced ROS1-positive non-small cell lung cancer. Learn more at IBTROZI.com.

About the TRUST Clinical Program

The TRUST clinical program evaluating IBTROZI for the treatment of adult patients with advanced ROS1+ NSCLC included two Phase 2 single-arm pivotal studies: TRUST-I (NCT04395677) in China, which enrolled 173 patients, and TRUST-II (NCT04919811), a global study, which enrolled 164 patients. The primary endpoint of these registrational studies is confirmed objective response rate (cORR) as assessed by an independent review committee (IRC). Secondary endpoints include intracranial cORR, duration of response, progression-free survival, and safety.

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^TM (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.
