"This quarter, we built momentum with achievement of key milestones advancing azenosertib in our registration-intended Phase 2 and Phase 3 trials for patients with Cyclin E1-positive platinum-resistant ovarian cancer (PROC)," said Julie Eastland, Chief Executive Officer of Zentalis. "Our core focus is on bringing a convenient, oral, non-chemotherapy treatment option to approximately 50% of PROC patients who are Cyclin E1-positive and may experience poorer prognosis and limited benefit from standard-of-care therapies. Pivotal dose selection supports our regulatory strategy, positioning us to pursue accelerated approval through the DENALI Part 2 trial while simultaneously advancing ASPENOVA as our confirmatory trial—together charting a pathway to bring a potential first-in-class therapy to market for this underserved patient population. Following dose selection, we initiated pre-commercial launch preparedness activities to add commercial capabilities to the organization, scale manufacturing capacity and advance Cyclin E1 companion diagnostic market development. Beyond the lead indication, we see substantial opportunity for strategic expansion of azenosertib into platinum-sensitive or first-line maintenance settings of ovarian cancer, additional tumor types, and combination approaches."

"With a cash position of $211.8 million as of March 31, 2026, we have runway into late 2027 and the resources to support execution of key milestones, most importantly the DENALI Part 2 topline readout, and ongoing trials," Ms. Eastland continued.

Clinical Development Progress
•Pivotal Dose Selected for Registration-Intended Azenosertib Monotherapy Program in Cyclin E1-Positive PROC: In April 2026, selected 400mg once daily on a 5-days-on, 2-days-off schedule (400mg QD 5:2) as the pivotal study dose for azenosertib monotherapy in patients with Cyclin E1-positive PROC based on a pre-specified interim analysis from DENALI Part 2a that showed a meaningful, clearly differentiated response rate at 400mg QD 5:2 and comparable safety profiles across both dose groups. The analysis revealed observed improvements in several key measures, including a discontinuation rate due to adverse events at approximately half the rate reported in DENALI Part 1b and no treatment-related deaths. Concurrently, the Company expanded DENALI Part 2 to include Part 2c, a new cohort broadening inclusion to approximately 40 patients previously treated with a taxane-containing regimen for PROC, to maintain alignment between the study population and the evolving treatment landscape. DENALI Parts 2b and 2c are currently enrolling. DENALI Part 2 is designed to support a potential accelerated approval pathway in the Cyclin E1 biomarker-selected patient population, subject to regulatory review. The Company expects to complete enrollment in all cohorts of DENALI Part 2 and provide a topline readout by year-end 2026.
•ASPENOVA Phase 3 First Patient Dosed: In May 2026, announced the first patient was dosed in the Phase 3 ASPENOVA confirmatory trial designed to satisfy FDA requirements for potential conversion to full approval and to support approval in major ex-US markets. ASPENOVA is a randomized, controlled Phase 3 trial that is expected to enroll approximately 420 patients and compare azenosertib monotherapy at 400mg QD 5:2 to investigator’s choice of standard-of-care single-agent chemotherapy (paclitaxel, pegylated liposomal doxorubicin, gemcitabine, or topotecan) in patients with Cyclin E1-positive PROC. The trial is currently enrolling.
•MUIR Part 2 dose expansion evaluating azenosertib in combination with bevacizumab as maintenance therapy in ovarian cancer. MUIR is a multi-part, open-label Phase 1b clinical trial evaluating the safety, efficacy and preliminary clinical activity of azenosertib as a combination therapy in patients with ovarian cancer. The dose expansion cohort of Part 2 is currently open for enrollment of azenosertib in combination with bevacizumab in second-line platinum-sensitive ovarian cancer (PSOC) patients for maintenance treatment, whose disease progressed while on a PARP inhibitor.

Medical Meeting Presentations Supporting Pipeline Strategy
•AACR 2026: Presented two posters at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting featuring: (1) compelling preclinical data showing azenosertib combinations can induce complete tumor responses in a model resistant to emerging antibody-drug conjugate (ADC) therapies in triple-negative breast cancer (TNBC), supporting the potential for pipeline expansion beyond ovarian cancer; and (2) real-world data from two independent cohorts demonstrating that Cyclin E1-positive ovarian cancer patients experience significantly worse clinical outcomes, independent of CCNE1 gene amplification status, reinforcing the potential for azenosertib to address the unmet need for these patients.
•ASCO 2026 Abstract Acceptance: Announced that the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) has accepted an abstract for presentation at the 2026 ASCO (Free ASCO Whitepaper) Annual Meeting featuring results from Part 1 of the Phase 1b MUIR trial, focusing on an evaluation of azenosertib in combination with paclitaxel in platinum-resistant ovarian cancer (PROC). The data will showcase combinability and activity in an all-comer setting, demonstrating the broad potential for azenosertib in multiple lines of ovarian cancer and other tumor types.

First Quarter 2026 Financial Results
•Cash Position: Cash, cash equivalents and marketable securities were $211.8 million as of March 31, 2026, compared to $245.9 million as of December 31, 2025. The Company believes that its existing cash, cash equivalents and marketable securities as of March 31, 2026 will be sufficient to fund its operating expenses and capital expenditure requirements into late 2027.
•Research and Development Expenses: Research and development (R&D) expenses for the three months ended March 31, 2026 were $28.7 million, compared to $27.2 million for the three months ended March 31, 2025. The increase of $1.5 million was primarily due to an increase of $6.8 million related to clinical expenses and drug manufacturing, including costs associated with advancing the DENALI and ASPENOVA trials. This increase was partially offset by decreases of $3.9 million for personnel expense, of which $1.2 million was non-cash stock-based compensation, a decrease of $1.2 million related to a one-time impairment charge recorded in Q1 2025, and a decrease of $0.2 million for allocated overhead.
•General and Administrative Expenses: General and administrative expenses for the three months ended March 31, 2026 were $9.1 million, compared to $10.6 million during the three months ended March 31, 2025. This decrease of $1.5 million was attributable to a decrease of $2.0 million in personnel expense, of which $1.2 million was non-cash stock-based compensation. The decrease was partially offset by an increase of $0.5 million related to consulting, outside services and other allocated costs.
•Total Operating Expenses: Total operating expenses were $37.9 million for the three months ended March 31, 2026, compared to $45.6 million for the three months ended March 31, 2025. Total operating expenses for the first quarter of 2025 included a non-recurring $7.8 million expense associated with the strategic restructuring announced in January 2025.
About Azenosertib
Azenosertib is an investigational, potentially first-in-class, selective, and orally bioavailable inhibitor of WEE1 currently being evaluated in clinical studies in ovarian cancer and additional tumor types. WEE1 acts as a master regulator of the G1-S and G2-M cell cycle checkpoints, through negative regulation of both CDK1 and CDK2, to prevent replication of cells with damaged DNA. By inhibiting WEE1, azenosertib enables cell cycle progression, despite high levels of DNA damage, thereby resulting in the accumulation of DNA damage and leading to mitotic catastrophe and cancer cell death.

Azenosertib is in late-stage development as a potential treatment for Cyclin E1-positive platinum-resistant ovarian cancer (PROC). There is currently no approved treatment option specifically for this biomarker-selected population which comprises approximately 50% of PROC patients. Cyclin E1 protein overexpression has been established as a sensitive and specific predictive biomarker for identifying patients who could potentially derive benefit from azenosertib treatment, based on retrospective analysis of azenosertib studies in PROC. Validation of the Cyclin E1 companion diagnostic assay is ongoing in the DENALI and ASPENOVA trials.

Azenosertib has been granted Fast Track Designation by the U.S. FDA for the treatment of patients with Cyclin E1-positive platinum-resistant ovarian cancer. Fast Track Designation is intended to facilitate the development and expedite the review of therapies that have the potential to treat serious conditions and address unmet medical needs.

About DENALI Clinical Trial
DENALI is a multi-part Phase 2 registration-intended clinical trial (NCT05128825) studying azenosertib in PROC patients.

Part 1b enrolled patients with PROC regardless of Cyclin E1 protein expression, all treated at 400mg QD 5:2. Part 2 is prospectively enrolling PROC patients with Cyclin E1 protein overexpression based on Zentalis’ proprietary immunohistochemistry cutoff.

Part 2, in total, is designed to support accelerated approval, pending positive study outcomes and further discussions with the FDA. The study design consists of the following parts:
•Part 2a: Dose confirmation evaluated two doses, 300mg QD 5:2 and 400mg QD 5:2, with approximately 30 patients enrolled per dose group. 400mg QD 5:2 was selected as the optimal monotherapy dose. Recruitment at the 300mg QD 5:2 dose level has been discontinued. All patients enrolled in Part 2a will contribute to the overall safety database submitted to the FDA.
•Part 2b: Enrollment expansion at the selected 400mg QD 5:2 dose up to approximately 100 patients, including patients at this dose in Part 2a. This cohort is currently enrolling.
•Part 2c: Broadening study population, which is expected to include approximately 40 patients previously treated with a taxane-containing regimen for PROC. This cohort is currently enrolling.

Zentalis expects to complete enrollment in all cohorts of DENALI Part 2 (2a, 2b, 2c) and provide a topline readout by year-end 2026.

About ASPENOVA Clinical Trial
ASPENOVA is a Phase 3 randomized, confirmatory clinical trial designed to support full approval of azenosertib in patients with Cyclin E1-positive PROC. The trial is expected to enroll approximately 420 patients and compare azenosertib monotherapy at 400mg QD 5:2 to investigator’s choice of standard-of-care single-agent chemotherapy (paclitaxel, pegylated liposomal doxorubicin [PLD], gemcitabine, or topotecan) in this biomarker-selected population. The primary endpoint is progression-free survival (PFS); key secondary endpoints include overall survival (OS) and overall response rate (ORR). The trial design was based on feedback from the U.S. FDA regarding requirements for seeking approval under the accelerated approval pathway and requirements to support potential conversion to full approval.

About MUIR Clinical Trial
MUIR (NCT04516447) is a multi-part, open-label Phase 1b clinical trial evaluating the safety, efficacy and preliminary clinical activity of azenosertib combinations in patients with ovarian cancer.
Part 1 enrolled patients with platinum-resistant ovarian cancer (PROC) treated with azenosertib in combination with one of four chemotherapy regimens: carboplatin, gemcitabine, pegylated liposomal doxorubicin, or paclitaxel. Primary objectives are safety and tolerability, with key secondary objectives including clinical activity assessed by objective response rate, duration of response, and progression-free survival per RECIST v1.1.

Part 2 is evaluating azenosertib plus bevacizumab as maintenance regimen (first [1L] or second line [2L]) in patients with advanced ovarian, peritoneal, or fallopian tube cancer following platinum-based chemotherapy. The dose expansion portion will evaluate azenosertib at the recommended dose in combination with bevacizumab in patients with platinum-sensitive ovarian cancer in 2L who progressed while on a PARP inhibitor for 1L maintenance. The primary objective is safety and tolerability; secondary objectives include preliminary clinical activity of the combination as assessed by progression-free survival for the dose expansion portion. The dose expansion portion is currently open for enrollment.

"We ended the first quarter of 2026 with strong momentum across our pipeline of highly differentiated I-O therapies leveraging our best-in-class masking technology," said René Russo, Pharm.D., president and chief executive officer of Xilio. "XTX501 has the potential to be a foundational backbone therapy for combination regimens across a broad range of solid tumors, and we are on track to advance this program into the clinic this year. In addition, our recent data for our CLDN18.2 program presented at AACR (Free AACR Whitepaper) further demonstrate the power of our masking technology to unlock the potential of T cell engagers. This progress, together with the recent achievement of another financial milestone under our AbbVie collaboration, highlights the productivity of our pipeline and underscores our ability to maximize the value of our clinically-validated masking technology."

Pipeline Progress and Business Updates

XTX501: bispecific PD-1 / masked IL-2

XTX501 is a novel bispecific PD-1 / masked IL-2 that has the potential to be a foundational "backbone" therapy for combination treatment with other agents. XTX501 is designed to selectively stimulate PD-1 positive, antigen-experienced T cells and enhance their function while overcoming IL-2 receptor-mediated clearance, peripheral activity and tolerability issues associated with non-masked IL-2 agents. In preclinical studies, XTX501 demonstrated robust monotherapy activity (including in settings insensitive to PD-1 therapy) and tumor-selective pharmacodynamics consistent with its intended mechanism of action.


Xilio is currently advancing XTX501 through investigational new drug (IND)-enabling studies and plans to submit an IND application in the middle of 2026.

Xilio plans to initiate a Phase 1 trial for XTX501 in the second half of 2026 and report initial Phase 1 data in patients with metastatic non-small cell lung cancer in the second half of 2027, subject to clearance of the IND by the U.S. Food and Drug Administration.

Masked T Cell Engager Programs

Xilio is leveraging its proprietary, clinically-validated masking technology and modular T cell engager (TCE) architectures to advance two wholly-owned masked TCE programs, as well as an additional masked TCE program in collaboration with AbbVie Group Holdings Limited (AbbVie).

Xilio’s masked TCEs include a masked CD3 targeting domain and one or more tumor-associated antigen (TAA) binding domains (which may be masked) as part of the core molecule design. Depending on the desired properties that Xilio is seeking to achieve for a particular molecule, Xilio’s modular architecture enables the ability to incorporate a co-stimulatory domain designed to further enhance potency and durability of T cell response, include multiple TAA binding domains and/or also mask the TAA binding domain(s) and/or co-stimulatory signaling domain. Upon tumor-selective activation, Xilio’s TCE molecules are designed to release a potent, short half-life TCE in the tumor microenvironment.


Xilio is advancing XTX601, a potential first-in-class masked TCE targeting CLDN18.2, a TAA expressed in gastrointestinal cancers (gastric, pancreatic and esophageal). In parallel, Xilio is leveraging its modular design architecture to evaluate designs that incorporate masking of the CLDN18.2 binding domain and/or the addition of a co-stimulatory domain. Xilio initiated IND-enabling activities for its CLDN18.2 program in the first quarter of 2026.

In April 2026, Xilio presented new preclinical data for XTX601 at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting demonstrating protease-dependent, tumor-selective activation and potent anti-tumor activity in multiple preclinical models. In addition, XTX601 was well-tolerated in non-human primates with a favorable therapeutic index. For more information, read the press release here.

Xilio is also advancing a potential first-in-class multi-specific, masked TCE program targeting PSMA and STEAP1 with built-in co-stimulatory signaling. PSMA and STEAP1 are expressed in most prostate cancer tumors, and targeting both TAAs with a single molecule has the potential to address tumor heterogeneity while minimizing the potential for resistance due to antigen escape. Xilio anticipates initiating IND-enabling activities for its PSMA+STEAP1 program in the second quarter of 2026.

Xilio plans to submit IND applications for its CLDN18.2 and PSMA+STEAP1 programs in 2027.

Efarindodekin alfa: masked IL-12


Xilio is evaluating efarindodekin alfa as a monotherapy in an ongoing Phase 2 clinical trial in patients with advanced solid tumors and expects to deliver an option data package to Gilead Sciences, Inc. (Gilead) in the first half of 2027.

Recent Corporate Updates

Xilio strengthened its board of directors with the appointment of Cheryl R. Blanchard, Ph.D., a renowned biopharmaceutical leader, in April 2026. Dr. Blanchard brings more than 30 years of leadership experience to Xilio, with deep scientific, operational and commercial leadership in life science companies.

In the second quarter of 2026, Xilio achieved a $6.0 million development milestone related to the masked antibody-based immunotherapy program under the company’s collaboration, license and option agreement with AbbVie.

"Our first quarter performance reflects accelerating growth in market demand for YCANTH as the new standard of care for the treatment of molluscum contagiosum, a condition that impacts approximately 6 million people in the United States alone," said Jayson Rieger, PhD, MBA, President and Chief Executive Officer of Verrica. "As the only FDA-approved, HCP-administered therapy for molluscum, YCANTH is a product that is uniquely positioned to address the unmet need of patients with molluscum, largely children under the age of 14. Demand for YCANTH grew sharply during the first quarter, as we set new records for dispensed applicator units during the quarter and in the month of March. April dispensed applicator units increased further from the record total in March, and the Company has achieved the milestone of over 100,000 total dispensed applicator units since launch. We have also achieved another significant milestone in expanding to new markets as our partner, Torii Pharmaceutical, launched YCANTH in Japan for patients with molluscum following regulatory approval last year."

"We are beginning to realize the traction from the efforts we began to implement last year to stabilize and grow our business. Alongside the growth in demand for YCANTH, we believe Verrica’s future growth is enhanced by the potential of our late-stage clinical programs in basal cell carcinoma and common warts, which we believe could represent multi-billion dollar opportunities if these programs successfully complete their development and are approved," Dr. Rieger continued. "The exciting data from the Phase 2 study of our novel oncolytic peptide, VP-315, for the treatment of basal cell carcinoma is generating strong interest within the dermatology and oncology communities and among patients faced with treating basal cell carcinoma. Further, last December the first patient was dosed in the first trial (COVE-2) of the global Phase 3 program evaluating YCANTH (VP-102) for the treatment of common warts, and we are happy to announce achievement of over 50% of the current targeted enrollment in the trial. We expect the second Phase 3 trial (COVE-3) in the common warts program, with sites in both the U.S. and Japan, will be initiated in mid-2026. If successful, the global Phase 3 program in common warts has the potential to greatly expand the market for YCANTH to an indication with an estimated 22 million patients in the United States. The efforts we are undertaking in commercializing YCANTH for molluscum lay the foundation for an efficient and rapid expansion into common warts, if approved, as there will be a significant overlap in the clinicians treating both indications who would have the ability to access the product for both patient populations through the same distribution channels."

Dr. Rieger concluded, "we are proud of our progress in establishing YCANTH as the new standard of care for molluscum and of our work to expand our products, indications and markets. Collectively, our commercially available asset and pipeline programs, if successful, could represent significant benefits for patients and value for our company and our shareholders."

Business Highlights and Recent Developments

YCANTH (VP-102)


During the first quarter of 2026, YCANTH dispensed applicator units totaled 15,302, representing a year-over-year increase of approximately 51.3% from the first quarter of 2025. On a sequential basis, YCANTH dispensed applicator units increased approximately 12.1% from the prior quarter. In the first quarter of 2026, while January was likely impacted by winter weather across the East Coast, dispensed applicator units per selling day rebounded sharply in February and March, setting a record monthly high since launch in March.


On February 9, 2026, the Company announced the commercial launch of YCANTH in Japan by its partner, Torii Pharmaceutical Co. Ltd. ("Torii"), a wholly-owned subsidiary of Shionogi & Co., Ltd., for the treatment of molluscum.


On January 7, 2026, the Company announced that the first patient was dosed in December 2025 in the first trial (COVE-2) of our global Phase 3 program evaluating YCANTH (VP-102) for the treatment of common warts. If the Phase 3 program is successful, YCANTH could become the first therapy approved in either the United States or Japan for the treatment of common warts, a condition that impacts over 22 million people in the United States alone. The Company has retained full commercial rights for all potential YCANTH indications outside of Japan and believes that YCANTH for common warts could represent a substantial commercial and licensing opportunity.

VP-315


On May 5, 2026, the Company announced that it will present data from its Phase 2 study of its novel oncolytic peptide, VP-315, for the treatment of basal cell carcinoma in a late-breaking abstract selected for oral presentation at the upcoming 2026 Society for Investigative Dermatology (SID) Annual Meeting, which will take place from May 13-16, 2026, in Chicago, Illinois. Data from the Company’s Phase 2 study will highlight an observed abscopal-like effect of VP-315 in non-treated basal cell carcinoma lesions.

CORPORATE


On February 12, 2026, the Company announced the appointment of Chris Chapman as its Chief Commercial Officer. Mr. Chapman brings over 25 years of commercial experience in the pharmaceutical industry to Verrica, and most recently served as Chief Commercial Officer at Dermavant Sciences through its acquisition by Organon, where he played an instrumental role in launching VTAMA (tapinarof) cream, 1%, approved for adult plaque psoriasis in June 2022 and atopic dermatitis in December 2024.

First Quarter 2026 Financial Results


Total revenue for the three months ended March 31, 2026, was $5.0 million.


U.S. YCANTH product revenue, net was $4.3 million for the quarter ended March 31, 2026, compared to net product revenue of $3.4 million for the quarter ended March 31, 2025. The increase in product revenue, net was primarily related to an increase in deliveries of YCANTH to Verrica’s distribution partners commensurate with an increase in dispensed applicator unit volume.


License and collaboration revenue was $0.7 million for the quarter ended March 31, 2026, consisting primarily of commercial supply for Torii’s YCANTH launch in Japan. License and collaboration revenue was not material for the three months ended March 31, 2025.


Costs of product revenue were $0.5 million for the quarter ended March 31, 2026, compared to $0.4 million for the quarter ended March 31, 2025, consisting primarily of product costs related to the sale of YCANTH.


Selling, general and administrative expenses were $10.0 million for the quarter ended March 31, 2026, compared to $8.8 million for the same period in 2025. Excluding the impact of stock-based compensation, the increase of $1.3 million was primarily due to increased commercial spend, related to the expansion of the sales force.


Research and development expenses were $3.9 million for the quarter ended March 31, 2026, compared to $2.3 million for the same period in 2025. Excluding the impact of stock-based compensation, the increase was primarily attributable to costs associated with the Phase 3 program for common warts. The expense for the Phase 3 common warts program did not impact Verrica’s cash balance, as the first $40 million of payments for this program will be made by Torii under the Company’s collaboration and license agreement.


Interest income was $0.2 million for the quarter ended March 31, 2026, compared to $0.3 million for the quarter ended March 31, 2025. The decrease in interest income was primarily due to lower cash balances.


Interest expense was $0.2 million for the quarter ended March 31, 2026, compared to $2.2 million for the same period in 2025. The decrease of $2.0 million was related to the settlement and termination of the Company’s debt facility in November 2025.


For the quarter ended March 31, 2026, net loss was $9.7 million, or $0.45 per share, compared to a net loss of $9.7 million, or $1.03 per share, for the same period in 2025.


For the quarter ended March 31, 2026, non-GAAP net loss was $8.8 million, or $0.41 per share, compared to a non-GAAP net loss of $8.3 million, or $0.88 per share, for the same period in 2025.

About Revuforj (revumenib)

Revuforj (revumenib) is an oral, first-in-class menin inhibitor that is FDA approved for the treatment of relapsed or refractory (R/R) acute leukemia with a lysine methyltransferase 2A gene (KMT2A) translocation as determined by an FDA-authorized test in adult and pediatric patients one year and older. Revuforj is also indicated for the treatment of R/R acute myeloid leukemia (AML) with a susceptible nucleophosmin 1 (NPM1) mutation in adult and pediatric patients one year and older who have no satisfactory alternative treatment options.

Multiple trials of revumenib are ongoing or planned across the treatment landscape, including in combination with standard of care therapies in newly diagnosed patients with NPM1m or KMT2Ar AML.

Revumenib was previously granted Orphan Drug Designation for the treatment of AML, ALL and acute leukemias of ambiguous lineage (ALAL) by the U.S. FDA and for the treatment of AML by the European Commission. The U.S. FDA also granted Fast Track designation to revumenib for the treatment of adult and pediatric patients with R/R acute leukemias harboring a KMT2A rearrangement or NPM1 mutation and Breakthrough Therapy Designation for the treatment of adult and pediatric patients with R/R acute leukemia harboring a KMT2A rearrangement.

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.
