Dapolsertib is a first-in-class oral dual PIM/FLT3 kinase inhibitor that has demonstrated preclinical antitumor activity and synergy with anti-CD20-directed therapies. The abstract reports the first clinical results from Group 2 of the JASPIS-01 study, which evaluates dapolsertib monotherapy (125 mg orally once daily on days 1-14 of 21-day cycles) in adults with r/r aggressive B-NHL who have exhausted available standard treatment options following at least two prior systemic therapies. Clinical activity was observed in heavily pretreated patients. The safety profile was manageable and allowed dosing of dapolsertib at the intended dose level.

"Patients with aggressive B-cell lymphoma whose disease progresses after CAR-T cell therapy and bispecific antibodies have limited treatment options and face very poor outcomes," said Elcin Barker Ergun, CEO of the Menarini Group. "The encouraging initial findings in heavily pretreated patients support the continued clinical development of dapolsertib, a first-in-class oral dual PIM/FLT3 inhibitor, as a potential option for this grim disease, and we look forward to further results from the ongoing study."

"We are very pleased that the first clinical data from JASPIS-01 will be presented at ASH (Free ASH Whitepaper), a leading hematology meeting. The activity seen in the JASPIS-01 study are particularly encouraging, given the highly aggressive biology of the disease in this population," said Hendrik Nogai, M.D., Chief Medical Officer of Ryvu Therapeutics. "As dapolsertib inventors and Menarini’s operational partner for the study, we remain committed to advancing dapolsertib for patients with aggressive B-cell lymphoma, who urgently need new treatment options."

Details on the poster presentation are as follows:

"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 profile that 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) (Free ESMO Whitepaper) 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.

Conference Call and Webcast
Nuvation Bio will host a conference call and webcast today, November 4, 2026, at 4:30 p.m. ET to discuss its financial results for the third quarter of 2026 and provide business updates.

Investors and the general public are invited to listen to the live webcast and may register on the Investor Relations section of the Nuvation Bio website.

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.

In the randomized, double-blind, multicenter Phase III registrational study HARMONi-GI1 (AK112-309), ivonescimab plus chemotherapy demonstrated superior survival benefit for patients versus durvalumab plus chemotherapy, the current global standard for the first-line treatment of BTC. In a prespecified interim analysis reviewed by the Independent Data Monitoring Committee (IDMC), HARMONi-GI1 met its primary endpoint of overall survival (OS), with the ivonescimab plus chemotherapy arm demonstrating statistically significant and clinically meaningful improvement over the control arm. The trial also met all key secondary endpoints, including progression-free survival (PFS) and objective response rate (ORR).

The HARMONi-GI1 results were presented as a Late-Breaking Abstract in an oral presentation at the ESMO (Free ESMO Whitepaper) Presidential Symposium in October 2026. HARMONi-GI1 is the first Phase III trial in BTC to show statistically significant overall survival benefit against the established PD-L1 inhibitor plus chemotherapy standard of care.

On October 21, 2026, Summit announced a clinical trial collaboration with ECOG-ACRIN Cancer Research Group (ECOG-ACRIN) to evaluate the safety and efficacy of ivonescimab with chemotherapy compared to pembrolizumab or durvalumab plus chemotherapy in a registration-enabling Phase II/III study (EA2251), in the first-line treatment of patients with advanced BTC.

About Revuforj (revumenib)

Revuforj (revumenib) is the first and only menin inhibitor that is FDA approved for the treatment of adult and pediatric patients one year and older with relapsed or refractory (R/R) acute myeloid leukemia (AML) with a susceptible NPM1 mutation who have no satisfactory alternative treatment options or R/R acute leukemia with a KMT2A translocation as determined by an FDA-authorized test.

Multiple trials of revumenib are underway across the acute leukemia treatment continuum, including in combination with standard of care therapies in newly diagnosed patients with NPM1m or KMT2Ar AML.

About Niktimvo (axatilimab-csfr)

Niktimvo (axatilimab-csfr) is a first-in-class colony stimulating factor-1 receptor (CSF-1R)-blocking antibody approved for use in the U.S. for the treatment of chronic graft-versus-host disease (GVHD) after failure of at least two prior lines of systemic therapy in adult and pediatric patients weighing at least 40 kg (88.2 lbs).

In 2016, Syndax licensed exclusive worldwide rights to develop and commercialize axatilimab from UCB. In September 2021, Syndax and Incyte entered into an exclusive worldwide co-development and co-commercialization license agreement for axatilimab in chronic GVHD and any future indications.

Axatilimab is being studied in frontline combination trials in chronic GVHD – a Phase 2 combination trial with ruxolitinib (NCT06388564) and a Phase 3 combination trial with steroids (NCT06585774) are underway.

Revuforj (revumenib)

IMPORTANT SAFETY INFORMATION

WARNING: DIFFERENTIATION SYNDROME, QTc PROLONGATION, and TORSADES DE POINTES

Differentiation syndrome, which can be fatal, has occurred with Revuforj. Signs and symptoms may include fever, dyspnea, hypoxia, pulmonary infiltrates, pleural or pericardial effusions, rapid weight gain or peripheral edema, hypotension, and renal dysfunction. If differentiation syndrome is suspected, immediately initiate corticosteroid therapy and hemodynamic monitoring until symptom resolution.

QTc prolongation and Torsades de Pointes have occurred in patients receiving Revuforj. Correct hypokalemia and hypomagnesemia prior to and during treatment. Do not initiate Revuforj in patients with QTcF > 450 msec. If QTc interval prolongation occurs, interrupt, reduce, or permanently discontinue Revuforj.

WARNINGS AND PRECAUTIONS

Differentiation Syndrome: Revuforj can cause fatal or life-threatening differentiation syndrome (DS). Symptoms of DS, including those seen in patients treated with Revuforj, include fever, dyspnea, hypoxia, peripheral edema, pleuropericardial effusion, acute renal failure, rash, and/or hypotension.

In clinical trials, DS occurred in 60 (25%) of 241 patients treated with Revuforj at the recommended dosage for relapsed or refractory acute leukemia. Among those with a KMT2A translocation, DS occurred in 33% of patients with acute myeloid leukemia (AML), 33% of patients with mixed-phenotype acute leukemia (MPAL), and 9% of patients with acute lymphoblastic leukemia (ALL); DS occurred in 18% of patients with NPM1m AML. DS was Grade 3 or 4 in 12% of patients and fatal in 2 patients. The median time to initial onset was 9 days (range 3-41 days). Some patients experienced more than 1 DS event. Treatment interruption was required for 7% of patients, and treatment was withdrawn for 1%.

Reduce the white blood cell count to less than 25 Gi/L prior to starting Revuforj. If DS is suspected, immediately initiate treatment with systemic corticosteroids (e.g., dexamethasone 10 mg IV every 12 hours in adults or dexamethasone 0.25 mg/kg/dose IV every 12 hours in pediatric patients weighing less than 40 kg) for a minimum of 3 days and until resolution of signs and symptoms. Institute supportive measures and hemodynamic monitoring until improvement. Interrupt Revuforj if severe signs and/or symptoms persist for more than 48 hours after initiation of systemic corticosteroids, or earlier if life-threatening symptoms occur such as pulmonary symptoms requiring ventilator support. Restart steroids promptly if DS recurs after tapering corticosteroids.

QTc Interval Prolongation and Torsades de Pointes: Revuforj can cause QT (QTc) interval prolongation and Torsades de Pointes.

Of the 241 patients treated with Revuforj at the recommended dosage for relapsed or refractory acute leukemia in clinical trials, QTc interval prolongation was reported as an adverse reaction in 86 (36%) patients. QTc interval prolongation was Grade 3 in 15% and Grade 4 in 2%. The heart-rate corrected QT interval (using Fridericia’s method) (QTcF) was greater than 500 msec in 10%, and the increase from baseline QTcF was greater than 60 msec in 24%. Revuforj dose reduction was required for 7% due to QTc interval prolongation. QTc prolongation occurred in 21% of the 34 patients less than 17 years old, 35% of the 146 patients 17 years to less than 65 years old, and 46% of the 61 patients 65 years or older. One patient had a fatal outcome of cardiac arrest, and one patient had non-sustained Torsades de Pointes.

Correct electrolyte abnormalities, including hypokalemia and hypomagnesemia, prior to and throughout treatment with Revuforj. Perform an electrocardiogram (ECG) prior to initiation of Revuforj, and do not initiate Revuforj in patients with QTcF >450 msec. Perform an ECG at least once weekly for the first 4 weeks and at least monthly thereafter. In patients with congenital long QTc syndrome, congestive heart failure, electrolyte abnormalities, or those who are taking medications known to prolong the QTc interval, more frequent ECG monitoring may be necessary. Concomitant use with drugs known to prolong the QTc interval may increase the risk of QTc interval prolongation.

Interrupt Revuforj if QTcF increases >480 msec and <500 msec, and restart Revuforj at the same dose twice daily after the QTcF interval returns to ≤480 msec
Interrupt Revuforj if QTcF increases >500 msec or by >60 msec from baseline, and restart Revuforj twice daily at the lower-dose level after the QTcF interval returns to ≤480 msec
Permanently discontinue Revuforj in patients with ventricular arrhythmias and in those who develop QTc interval prolongation with signs or symptoms of life-threatening arrhythmia
Embryo-Fetal Toxicity: Revuforj can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential and males with female partners of reproductive potential to use effective contraception during treatment with Revuforj and for 4 months after the last dose of Revuforj.

ADVERSE REACTIONS

Fatal adverse reactions occurred in 9 (4%) patients who received Revuforj, including 4 with sudden death, 2 with differentiation syndrome, 2 with hemorrhage, and 1 with cardiac arrest.

Serious adverse reactions were reported in 184 (76%) patients. The most frequent serious adverse reactions (≥10%) were infection (29%), febrile neutropenia (20%), bacterial infection (15%), differentiation syndrome (13%), and hemorrhage (11%).

The most common adverse reactions (≥20%) including laboratory abnormalities, were phosphate increased (51%), hemorrhage (48%), nausea (48%), infection without identified pathogen (46%), aspartate aminotransferase increased (44%), alanine aminotransferase increased (40%), creatinine increased (38%), musculoskeletal pain (37%), febrile neutropenia (37%), electrocardiogram QT prolonged (36%), potassium decreased (34%), parathyroid hormone intact increased (34%), alkaline phosphatase increased (33%), diarrhea (29%), bacterial infection (27%), triglycerides increased (27%), phosphate decreased (25%), differentiation syndrome (25%), fatigue (24%), edema (24%), viral infection (23%), decreased appetite (20%), and constipation (20%).

DRUG INTERACTIONS

Drug interactions can occur when Revuforj is concomitantly used with:

Strong CYP3A4 inhibitors: reduce Revuforj dose
Strong or moderate CYP3A4 inducers: avoid concomitant use with Revuforj
QTc-prolonging drugs: avoid concomitant use with Revuforj. If concomitant use is unavoidable, obtain ECGs when initiating, during concomitant use, and as clinically indicated. Withhold Revuforj if the QTc interval is >480 msec. Restart Revuforj after the QTc interval returns to ≤480 msec
SPECIFIC POPULATIONS

Lactation: advise lactating women not to breastfeed during treatment with Revuforj and for 1 week after the last dose.

Pregnancy and testing: Revuforj can cause fetal harm when administered to a pregnant woman. Verify pregnancy status in females of reproductive potential within 7 days prior to initiating Revuforj.

Infertility: based on findings in animals, Revuforj may impair fertility. The effects on fertility were reversible.

Pediatric: monitor bone growth and development in pediatric patients.

Geriatric: no overall differences were observed in the effectiveness of Revuforj between patients who were 65 years and older, and younger patients. Compared to younger patients, the incidences of QTc prolongation and edema were higher in patients 65 years and older.
