5 Warnings And Precautions

•Risk of Infections: Do not initiate OJJAARA in patients with an active infection. Monitor for signs and symptoms of infection, including reactivation of hepatitis B, and initiate appropriate treatment promptly. (5.1)

•Thrombocytopenia and Neutropenia: Manage by dose reduction or interruption. (5.2)

•Hepatotoxicity: Obtain liver tests before initiation of and periodically throughout treatment with OJJAARA. (5.3)

•Major Adverse Cardiovascular Events (MACE): Monitor for symptoms, evaluate and treat promptly. (5.4)

•Thrombosis: Evaluate and treat symptoms of thrombosis promptly. (5.5)

•Malignancies: Monitor for development of secondary malignancies, particularly in current or past smokers. (5.6)

5.1 Risk of Infections

Serious (including fatal) infections (e.g., bacterial and viral, including COVID-19) occurred in 13% of patients treated with OJJAARA. Infections regardless of grade occurred in 38% of patients treated with OJJAARA [see Adverse Reactions (6.1)]. Delay starting therapy with OJJAARA until active infections have resolved. Monitor patients receiving OJJAARA for signs and symptoms of infection and initiate appropriate treatment promptly.

Hepatitis B Reactivation

Hepatitis B viral load (HBV-DNA titer) increases, with or without associated elevations in alanine transaminase (ALT) or aspartate transaminase (AST), have been reported in patients with chronic hepatitis B virus (HBV) infection taking Janus Kinase (JAK) inhibitors, including OJJAARA. The effect of OJJAARA on viral replication in patients with chronic HBV infection is unknown. In patients with HBV infections, check hepatitis B serologies prior to starting OJJAARA. If HBsAg and/or anti-HBc antibody is positive, consider consultation with a hepatologist regarding monitoring for reactivation versus prophylactic hepatitis B therapy. Patients with chronic HBV infection who receive OJJAARA should have their chronic HBV infection treated and monitored according to clinical HBV guidelines.

5.2 Thrombocytopenia and Neutropenia

OJJAARA can cause thrombocytopenia and neutropenia [see Adverse Reactions (6.1)].

New or worsening thrombocytopenia, with platelet count less than 50 × 10⁹/L, was observed in 20% of patients treated with OJJAARA. Eight percent of patients treated with OJJAARA had baseline platelet counts less than 50 × 10⁹/L.

Severe neutropenia, absolute neutrophil count (ANC) less than 0.5 × 10⁹/L, was observed in 2% of patients treated with OJJAARA.

Assess complete blood counts (CBC), including platelet and neutrophil counts, before initiating treatment and periodically during treatment as clinically indicated. Interrupt dosing or reduce the dose for thrombocytopenia or neutropenia [see Dosage and Administration (2.4)].

5.3 Hepatotoxicity

Two of the 993 patients with MF who received at least one dose of OJJAARA in clinical trials experienced reversible drug-induced liver injury. Overall, new or worsening elevations of ALT and AST (all grades) occurred in 23% and 24%, respectively, of patients treated with OJJAARA; Grade 3 and 4 transaminase elevations occurred in 1% and 0.5% of patients, respectively. New or worsening elevations of total bilirubin occurred in 16% of patients treated with OJJAARA. All total bilirubin elevations were Grades 1-2. The median time to onset of any grade transaminase elevation was 2 months, with 75% of cases occurring within 4 months.

Delay starting therapy in patients presenting with uncontrolled acute and chronic liver disease until apparent causes have been investigated and treated as clinically indicated. When initiating OJJAARA, refer to dosing in patients with hepatic impairment [see Dosage and Administration (2.3)].

Monitor liver tests at baseline, every month for 6 months during treatment, then periodically as clinically indicated. If increases in ALT, AST or bilirubin related to treatment are suspected, modify OJJAARA dosage based upon Table 1 [see Dosage and Administration (2.4)].

5.4 Major Adverse Cardiovascular Events (MACE)

Another JAK inhibitor increased the risk of MACE, including cardiovascular death, myocardial infarction, and stroke [compared with those treated with tumor necrosis factor (TNF) blockers] in patients with rheumatoid arthritis, a condition for which OJJAARA is not indicated.

Consider the benefits and risks for the individual patient prior to initiating or continuing therapy with OJJAARA, particularly in patients who are current or past smokers and patients with other cardiovascular risk factors. Inform patients receiving OJJAARA of the symptoms of serious cardiovascular events and the steps to take if they occur.

5.5 Thrombosis

Another JAK inhibitor increased the risk of thrombosis, including deep venous thrombosis, pulmonary embolism, and arterial thrombosis (compared with those treated with TNF blockers) in patients with rheumatoid arthritis, a condition for which OJJAARA is not indicated.

Evaluate patients with symptoms of thrombosis and treat appropriately.

5.6 Malignancies

Another JAK inhibitor increased the risk of lymphoma and other malignancies excluding nonmelanoma skin cancer (NMSC) (compared with those treated with TNF blockers) in patients with rheumatoid arthritis, a condition for which OJJAARA is not indicated. Current or past smokers were at increased risk.

Consider the benefits and risks for the individual patient prior to initiating or continuing therapy with OJJAARA, particularly in patients with a known malignancy (other than a successfully treated NMSC), patients who develop a malignancy, and patients who are current or past smokers.

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The safety of OJJAARA was evaluated in 215 patients in 2 clinical trials (MOMENTUM and SIMPLIFY-1 anemic subgroup [hemoglobin (Hb) <10 g/dL]) [see Clinical Studies (14)].

MOMENTUM

Patients in the MOMENTUM trial had been previously treated with a JAK inhibitor and were randomly assigned 2:1 to receive double-blind OJJAARA 200 mg orally once daily (n = 130) or danazol 300 mg orally twice daily (n = 65) for 24 weeks, after which they were eligible to receive open-label OJJAARA in an extended treatment phase. Among patients who received OJJAARA, 72% were exposed for 24 weeks or longer and 52% were exposed for 48 weeks or longer [see Clinical Studies (14)].

Serious adverse reactions occurred in 35% of patients who received OJJAARA during the randomized treatment period of the MOMENTUM trial; the most common serious adverse reactions (≥2%) included bacterial infection (8%), viral infection (5%), hemorrhage (4%), acute kidney injury (3%), pneumonia (3%), pyrexia (3%), thrombosis (3%), syncope (2%), thrombocytopenia (2%), and renal and urinary tract infection (2%). Fatal adverse reactions occurred in 12% of patients who received OJJAARA; the most common (≥2%) fatal adverse reaction was viral infection (5%).

Permanent discontinuation of OJJAARA due to an adverse reaction occurred in 18% of patients during the randomized treatment period of the MOMENTUM trial. Adverse reactions that resulted in permanent discontinuation (≥2%) included viral infection (2%) and thrombocytopenia (2%). Dosage reduction or treatment interruption due to an adverse reaction occurred in 34% of patients. Adverse reactions requiring dosage reduction and/or treatment interruption (≥2%) included thrombocytopenia (13%), bacterial infection (2%), diarrhea (2%), and neutropenia (2%).

Among the 130 patients treated with OJJAARA during the randomized treatment period of MOMENTUM, the most common adverse reactions (≥20%) were thrombocytopenia, diarrhea, hemorrhage, and fatigue (Table 2).

SIMPLIFY-1

Patients in the SIMPLIFY-1 trial were JAK inhibitor naïve and randomly assigned 1:1 to receive double-blind OJJAARA 200 mg orally once daily (n = 215) or ruxolitinib 5 to 20 mg orally twice daily (n = 217). Upon completion of the double-blind treatment phase, all patients were eligible to receive OJJAARA during the open-label phase. The safety of OJJAARA was evaluated in the population of patients with MF who were anemic at study entry. SIMPLIFY-1 enrolled 180 anemic patients who received OJJAARA (n = 85) or ruxolitinib (n = 95). Among these anemic patients who received OJJAARA, 78% were exposed for 24 weeks or longer and 61% were exposed for 48 weeks or longer [see Clinical Studies (14)].

Serious adverse reactions occurred in 28% of the anemic patients who received OJJAARA during the randomized treatment period of the SIMPLIFY-1 trial; the most common serious adverse reactions (≥2%) included bacterial infection (7%), pneumonia (6%), heart failure (4%) arrhythmia (2%), and respiratory failure (2%). A fatal adverse reaction (bacterial infection) occurred in 1 patient who received OJJAARA.

Permanent discontinuation of OJJAARA due to an adverse reaction occurred in 19% of the anemic patients during the randomized treatment period of the SIMPLIFY-1 trial. Adverse reactions that resulted in permanent discontinuation of OJJAARA (≥2%) included bacterial infection (2%), dizziness (2%), fatigue (2%), hypotension (2%), and thrombocytopenia (2%). Dosage reductions or treatment interruptions of OJJAARA due to an adverse reaction occurred in 21% of patients. Adverse reactions requiring dosage reduction and/or treatment interruption (≥2%) were thrombocytopenia (8%), pneumonia (4%), bacterial infection (2%), abdominal pain (2%), elevated liver enzymes (2%), and hypotension (2%).

Among the 85 anemic patients treated with OJJAARA during the randomized treatment period of SIMPLIFY-1, the most common adverse reactions (≥20%) were dizziness, fatigue, bacterial infection, hemorrhage, thrombocytopenia, diarrhea, and nausea (Table 3).

Other Adverse Reactions

Clinically relevant adverse reactions occurring in <5% of anemic patients in the MOMENTUM and SIMPLIFY-1 studies include:

Eye Disorders: Blurred vision.

Infections and Infestations: Fungal infection (excludes opportunistic infections).

Nervous System Disorders: Neuralgia, peripheral neuropathy, peripheral motor neuropathy, polyneuropathy.

Vascular Disorders: Flushing.

7 Drug Interactions

•Organic Anion Transporting Polypeptide (OATP)1B1/B3 inhibitors: Monitor for adverse reactions. (7.1)

•Breast Cancer Resistance Protein (BCRP) substrates: Reduce rosuvastatin (BCRP substrate) dosage. Follow approved product information recommendations for other BCRP substrates. (7.2)

7.1 Effect of Other Drugs on OJJAARA

Organic Anion Transporting Polypeptide (OATP)1B1/B3 Inhibitors

Momelotinib is an OATP1B1/B3 substrate. Concomitant use with an OATP1B1/B3 inhibitor increases momelotinib maximal concentrations (C_max) and area under the concentration-time curve (AUC) [see Clinical Pharmacology (12.3)], which may increase the risk of adverse reactions with OJJAARA. Monitor patients concomitantly receiving an OATP1B1/B3 inhibitor for adverse reactions and consider OJJAARA dose modifications [see Dosage and Administration (2.4)].

7.2 Effect of OJJAARA on Other Drugs

Breast Cancer Resistance Protein (BCRP) Substrates

Momelotinib is a BCRP inhibitor. OJJAARA may increase exposure of BCRP substrates, which may increase the risk of BCRP substrate adverse reactions [see Clinical Pharmacology (12.3)]. When administered concomitantly with OJJAARA, initiate rosuvastatin (BCRP substrate) at 5 mg and do not increase to more than 10 mg once daily. Dose adjustment of other BCRP substrates may also be needed. Follow approved product information recommendations for other BCRP substrates.

8 Use In Specific Populations

•Pregnancy: May cause fetal harm. (8.1)

•Lactation: Advise not to breastfeed. (8.2)

8.1 Pregnancy

Risk Summary

Available data on the use of OJJAARA in pregnant women are insufficient to determine whether there is a drug-associated risk for major birth defects or miscarriage. Based on animal reproduction studies conducted in rats and rabbits, momelotinib may cause embryo-fetal toxicity at exposures lower than the expected exposure in patients receiving 200 mg once daily (see Data). OJJAARA should only be used during pregnancy if the expected benefits to the mother outweigh the potential risks to the fetus.

The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Data

Animal Data: In an embryofetal development study, pregnant rats received momelotinib 2, 6 or 12 mg/kg/day orally, during the period of organogenesis (Gestation Day 6 to 17). Embryo-fetal toxicity (embryonic death, soft tissue anomalies, skeletal variations, and lower mean fetal body weights) was observed at 12 mg/kg (in the presence of maternal toxicity). Skeletal variations were observed (in the absence of maternal toxicity) at 6 mg/kg/day at exposures 3.5 times the exposure at the recommended human dose of 200 mg daily based on combined momelotinib and M21 (a major human metabolite) AUC. No developmental toxicity was observed at 2 mg/kg/day at exposures equivalent to the recommended dose (based on combined momelotinib and M21 AUC).

In an embryofetal developmental study, pregnant rabbits received momelotinib at 7.5, 30 or 60 mg/kg/day orally during the period of organogenesis (Gestation Day 7 to 20). Momelotinib was associated with maternal toxicity at 60 mg/kg/day, which resulted in reduced mean fetal weight, delayed bone ossification, and an abortion at less than the exposure at the recommended dose (based on combined momelotinib and M21 AUC). No developmental toxicity was observed at lower doses tested in rabbits.

In a pre- and post-natal development study, pregnant rats received momelotinib 2, 6 or 12 mg/kg/day orally from organogenesis through lactation (Gestation Day 6 to lactation Day 20). Decreased pup body weights and embryo-lethality were observed in the dams administered 6 and 12 mg/kg/day. Pup survival was significantly reduced in the 12 mg/kg/day group from birth to Day 4 of lactation. Momelotinib exposure in dams at 12 mg/kg and 6 mg/kg were approximately 2 times the exposure at the recommended dose (based on combined momelotinib and M21 AUC). The exposure in dams at the No Observed Adverse Effect Level (NOAEL) dose of 2 mg/kg was less than the exposure at the recommended dose (based on combined momelotinib and M21 AUC).

8.2 Lactation

Risk Summary

There are no data on the presence of momelotinib or its metabolites in human milk, the effects on the breastfed child, or the effects on milk production. It is not known whether OJJAARA is excreted in human milk. Momelotinib was present in rat pups following nursing from treated dams with adverse effects observed in the offspring. When a drug is present in animal milk, it is likely that the drug will be present in human milk. Because of the potential for serious adverse reactions in a breastfed child, patients should not breastfeed during treatment with OJJAARA, and for at least 1 week after the last dose of OJJAARA.

Data

Animal Data: In a pre- and postnatal development study, momelotinib was administered orally to rats during the lactation period; the drug was detected in plasma of nursing pups, which adversely affected pup survival.

8.3 Females and Males of Reproductive Potential

Contraception

Advise females of reproductive potential who are not pregnant to use highly effective contraception during therapy and for at least 1 week after the last dose of OJJAARA.

8.4 Pediatric Use

The safety and effectiveness of OJJAARA in pediatric patients have not been established.

8.5 Geriatric Use

There were 275 patients aged 65 years and older in the clinical studies for MF [see Clinical Studies (14)]. Of the total number of OJJAARA-treated patients in these studies, 163/216 (75%) were aged 65 years and older, and 63/216 (29%) were aged 75 years and older. No overall differences in safety or effectiveness of OJJAARA have been observed between patients aged 65 years and older and younger adult patients.

8.6 Hepatic Impairment

The recommended starting dose of OJJAARA in patients with severe hepatic impairment (Child-Pugh C) is 150 mg orally once daily [see Dosage and Administration (2.3)]. No dose modification is recommended for patients with mild hepatic impairment (Child-Pugh A) or moderate hepatic impairment (Child-Pugh B).

Momelotinib is extensively metabolized [see Clinical Pharmacology (12.3)]. Momelotinib exposure increased with severe hepatic impairment (Child-Pugh C). No clinically significant changes in momelotinib exposure were observed in subjects with mild hepatic impairment (Child-Pugh A) or moderate hepatic impairment (Child-Pugh B) [see Clinical Pharmacology (12.3)].

10 Overdosage

There is no known antidote for overdose with OJJAARA. If overdose is suspected, the patient should be monitored for signs or symptoms of adverse reactions or effects, and appropriate supportive treatment should be instituted immediately. Further management should be as clinically indicated. Hemodialysis is not expected to enhance the elimination of momelotinib.

11 Description

12 Clinical Pharmacology

12.1 Mechanism of Action

Momelotinib is an inhibitor of wild type Janus Kinase 1 and 2 (JAK1/JAK2) and mutant JAK2^V617F, which contribute to signaling of a number of cytokines and growth factors that are important for hematopoiesis and immune function. Momelotinib and its major human circulating metabolite, M21, have higher inhibitory activity for JAK2 compared to JAK3 and tyrosine kinase 2 (TYK2). Momelotinib and M21 additionally inhibit activin A receptor type 1 (ACVR1), also known as activin receptor like kinase 2 (ALK2), which produces subsequent inhibition of liver hepcidin expression and increased iron availability resulting in increased red blood cell production. MF is a myeloproliferative neoplasm associated with constitutive activation and dysregulated JAK signaling that contributes to inflammation and hyperactivation of ACVR1. JAK signaling recruits and activates STAT (signal transducers and activation of transcription) proteins resulting in nuclear localization and subsequent regulation of gene transcription.

12.2 Pharmacodynamics

Momelotinib inhibited STAT3 phosphorylation in whole blood from patients with MF. Maximal inhibition of STAT3 phosphorylation occurred 2 hours after momelotinib dosing and inhibition persisted for at least 6 hours [see Clinical Pharmacology (12.1)]. Iron availability and erythropoiesis was assessed by analysis of circulating hepcidin concentrations. An acute and sustained reduction of circulating hepcidin was observed for the duration of the 24-week administration of momelotinib to patients with MF [see Clinical Pharmacology (12.1)].

Cardiac Electrophysiology

Momelotinib did not prolong the QT interval to any clinically relevant extent at 4 times the highest recommended dosage of 200 mg.

12.3 Pharmacokinetics

Momelotinib pharmacokinetic parameters are presented as mean (%CV) and were derived in patients with MF unless otherwise specified.

The momelotinib steady-state C_max is 479 ng/mL (61%) and AUC is 3,288 ng•h/mL (60%) at the maximum recommended dosage. Momelotinib exposure (i.e., C_max and AUC) increases dose proportionally from 100 mg to 300 mg (0.5 to 1.5 times the maximum recommended dosage), but less than dose‑proportional at doses from 400 mg to 800 mg (2 to 4 times the maximum recommended dosage). There is no clinically significant accumulation.

Absorption

Median time to momelotinib C_max (T_max) at steady state is 2 hours (Q1: 1 hour; Q3: 3 hours) post dose.

Effect of Food

No clinically significant differences in momelotinib pharmacokinetics were observed following administration of either a high-fat meal (800 kcal; 50% fat) or low-fat meal (400 kcal; 20% fat) in healthy subjects.

Distribution

Momelotinib steady state apparent volume of distribution is 984 L (118%). Momelotinib plasma protein binding is approximately 91% in healthy volunteers.

Elimination

The elimination half-life of momelotinib and the M21 metabolite is 4 to 8 hours. Momelotinib clearance is 103 L/h (87%).

Metabolism: Momelotinib is metabolized by multiple cytochrome P450 (CYP) enzymes including CYP3A4 (36%), CYP2C8 (19%), CYP2C9 (17%), CYP2C19 (19%), and CYP1A2 (9%).

M21 is an active human metabolite that has approximately 40% of the pharmacological activity of the parent. M21 is formed by CYP followed by aldehyde oxidase metabolism of momelotinib. The mean M21 to momelotinib ratio for AUC ranged from 1.4 to 2.1.

Excretion: Following a single oral dose of radiolabeled momelotinib, 69% (13% unchanged) of radioactivity was excreted in feces and 28% (<1% unchanged) in urine. Approximately 12% of the administered dose was excreted in urine as M21.

Specific Populations

No clinically significant differences in momelotinib and M21 pharmacokinetics were observed based on age (range: 28 to 92 years), race (83% White, 6% Asian, 2% Black), sex (60% male), weight (range: 34 kg to 138 kg), renal impairment (eGFR: 16.4 mL/min/1.73 m² to above 120 mL/min/1.73 m²), or mild or moderate hepatic impairment (Child-Pugh A or B). The effect of end stage renal disease receiving dialysis on momelotinib pharmacokinetics is unknown.

Patients with Hepatic Impairment: Momelotinib C_max increased by 13% and AUC increased by 97% in subjects with severe hepatic impairment (Child-Pugh C). The M21 metabolite C_max decreased by 76% and AUC decreased by 48% in subjects with severe hepatic impairment (Child-Pugh C).

Drug Interaction Studies

Clinical Studies

OATP1B1/1B3 Inhibitors: Momelotinib C_max increased by 40% and AUC increased by 57% following concomitant use with a single dose of a OATP1B1/1B3 inhibitor (rifampin). The M21 metabolite C_max increased by 6% and AUC increased by 12%.

BCRP Substrates: A BCRP substrate (rosuvastatin) C_max increased by 220% and AUC increased by 170% following concomitant use of a single dose of rosuvastatin at 10 mg with multiple doses of momelotinib (200 mg once daily).

Other Drugs: No clinically significant differences in momelotinib and M21metabolite pharmacokinetics were observed when used concomitantly with a strong CYP3A4 inducer (tested with multiple-dose rifampin), a strong CYP3A4 inhibitor (ritonavir), or an acid reducing agent (omeprazole, a proton pump inhibitor).

No clinically significant differences in the pharmacokinetics of a CYP3A4 substrate (midazolam) were observed when used concomitantly with momelotinib.

In Vitro Studies

Cytochrome P450 (CYP) Enzymes: Momelotinib is a weak, reversible, time-independent inhibitor of CYP2B6 but does not inhibit CYP1A2, 2C8, 2C9, 2C19, 2D6, or 3A4/5. The M21 metabolite does not inhibit any of these CYP enzymes.

Momelotinib and M21 do not induce CYP3A4, CYP2C8, CYP2C9, or P-glycoprotein (P-gp).

Uridine diphosphate-glucuronosyltransferase (UGT): Momelotinib is an inhibitor of UGT1A1 and UGT1A9. The M21 metabolite is an inducer of UGT1A1.

Transporter Systems: Momelotinib and M21 are substrates in vitro for efflux transporters, P-gp and BCRP, and hepatic uptake transporters, OATP1B1/1B3. Momelotinib is an inhibitor of BCRP.

13 Nonclinical Toxicology

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

The carcinogenicity potential of momelotinib was assessed in rasH2 transgenic mice and Sprague-Dawley rats. There was no evidence of tumorigenicity in male or female mice that received momelotinib doses up to 100 mg/kg/day for 26 weeks. In a 2-year oral carcinogenicity study in Sprague-Dawley rats, momelotinib caused benign Leydig cell tumors at a dose of 15 mg/kg/day (17 times the maximum recommended dose based on combined momelotinib and M21 AUC). The increase in Leydig cell adenomas was considered related to a rat-specific phenomenon (i.e., prolactin-dependent Leydig cell tumorigenesis).

Momelotinib was not mutagenic in a bacterial reverse mutation assay, or clastogenic in an in vitro chromosomal aberration assay with human peripheral blood lymphocytes or in vivo in a rat bone marrow micronucleus assay.

In fertility studies in rats, momelotinib was administered for at least 70 days (males) and 14 days (females) prior to cohabitation and up to the implantation day (gestation Day 7) at doses of 5, 25, and 68 mg/kg/day. Momelotinib reduced sperm concentration and motility and reduced testes and seminal vesicle weights at 25 mg/kg/day or greater (approximately 13 times the recommended dose based on combined momelotinib and M21 AUC) leading to reduced fertility at 68 mg/kg/day. In females, momelotinib reduced ovarian function (reproductive cycles and ovulation) at 68 mg/kg/day and decreased the number of pregnant females and increased pre- and post-implantation loss with most pregnant rats having total litter loss at 25 mg/kg/day or greater. Exposures at the NOAEL in male and female rats at 5 mg/kg/day are approximately 3-times the recommended dose (based on combined momelotinib and M21 AUC).

14 Clinical Studies

The efficacy of OJJAARA in the treatment of adults with intermediate 1, intermediate 2, or high-risk MF, including primary MF, post-PV MF or post-ET MF, as defined by the Dynamic International Prognostic Scoring System (DIPSS) or International Prognostic Scoring System (IPSS) for MF, was established in the MOMENTUM trial and in a subpopulation of adults with anemia in the SIMPLIFY-1 trial. All patients received a starting dosage of OJJAARA 200 mg once daily. Eligible patients had baseline platelet count of ≥25 × 10⁹/L in MOMENTUM and ≥50 × 10⁹/L in SIMPLIFY-1.

MOMENTUM

MOMENTUM (NCT04173494) was a double-blind, 2:1 randomized, active-controlled trial in 195 symptomatic and anemic adults with MF who had previously received an approved JAK inhibitor therapy. Patients were treated with OJJAARA 200 mg once daily or danazol 300 mg twice daily for 24 weeks, then switched to open-label treatment with OJJAARA.

The median age was 71 years (range 38 to 86 years) with 79% of patients aged 65 years and older, and 63% of patients were male. Overall, 81% of patients were White, 9% of patients were Asian, 2% of patients were Black, and 6% of patients were Hispanic or Latino. Sixty-four percent of patients had primary MF, 19% had post-PV MF, and 17% had post-ET MF. Five percent of patients had intermediate-1 risk, 57% had intermediate-2 risk, and 35% had high-risk disease. Within the 8 weeks prior to treatment, 79% of patients had received red blood cell (RBC) transfusions (median of 4 RBC units; interquartile range: 1-6). At baseline, 13% and 15% of patients were transfusion independent (defined as no red blood cell transfusions in the 12 weeks before the first dose and Hb ≥8 g/dL) in the OJJAARA and danazol groups, respectively. The baseline median Hb count was 8 g/dL and the median platelet count was 96 × 10⁹/L (range 24 × 10⁹/L to 733 × 10⁹/L). The baseline median palpable spleen length was 11 cm below the left costal margin; the median central spleen volume measured by magnetic resonance imaging (MRI) or computed tomography (CT) was 2,105 cm³ (range 609 cm³ to 9,717 cm³).

Symptoms were measured using the Myelofibrosis Symptom Assessment Form (MFSAF v4.0) diary. The MFSAF v4.0 patient diary, completed throughout the randomized treatment period, captured the core symptoms of MF: fatigue (weariness and tiredness), night sweats (or feeling hot or flushed), itching, abdominal discomfort (feeling pressure or bloating), pain under ribs on left side, feeling of fullness after beginning to eat, and bone pain. For each li, symptom scores, ranging from 0 (absent) to 10 (worst imaginable), were added to create a daily Total Symptom Score (maximum score of 70). At baseline, the mean MFSAF v4.0 Total Symptom Score was 28 in the OJJAARA group and 26 in the danazol group.

The efficacy of OJJAARA in the treatment of patients with primary or secondary MF and anemia was established based on a significantly higher percentage of patients treated with OJJAARA compared to danazol achieving a MFSAF v4.0 Total Symptom Score reduction of 50% or more at Week 24 compared with their own baseline score (Table 4). Other endpoints included transfusion independence, spleen volume response, MFSAF v4.0 Total Symptom Score change from baseline, and percentage of patients with no transfusions.

SIMPLIFY-1

SIMPLIFY-1 (NCT01969838) was a double-blind, randomized, active-controlled trial in 432 adults with MF who had not previously received a JAK inhibitor. Patients were treated with OJJAARA 200 mg once daily or ruxolitinib adjusted dose twice daily for 24 weeks. Patients were eligible to switch to open-label OJJAARA after 24 weeks (without tapering of the JAK inhibitor received during the randomization period). The baseline characteristics and efficacy results provided are for the subset of patients who had anemia (Hb <10 g/dL) at baseline (n = 181).

The median age was 68 years (range 25 to 86 years) with 67% of patients aged 65 years and older, and 59% of patients were male. Eighty-one percent of patients were White, 8% of patients were Asian, 1% of patients were Black, and 2% of patients were Hispanic or Latino. Sixty-three percent of patients had primary MF, 13% had post-PV MF, and 24% had post-ET MF. Four percent of patients had intermediate-1 risk, 25% had intermediate-2 risk, and 71% had high-risk disease. At baseline, 29% and 44% of patients were transfusion independent in the groups treated with OJJAARA or ruxolitinib, respectively. The baseline median Hb measurement was 8.8 g/dL and the median platelet count was 193 × 10⁹/L (range 54 × 10⁹/L to 2,865 × 10⁹/L). Median palpable spleen length at baseline was 12 cm below the left costal margin; the median spleen volume at baseline (measured by MRI or CT) was 1,843 cm³ (range 352 cm³ to 9,022 cm³).

The efficacy of OJJAARA in the treatment of patients with MF in SIMPLIFY-1 was based on spleen volume response (reduction by 35% or greater). A numerically lower percent of patients treated with OJJAARA (25%) achieved a Total Symptom Score reduction of 50% or more at Week 24 compared with ruxolitinib (36%).

The spleen volume reduction results are presented in Table 5.
