Rulicent 10 mg is a selective inhibitor of the Janus Associated Kinases (JAKs) JAK1 and JAK2 (IC 50 values of 3.3 nM and 2.8 nM for JAK1 and JAK2 enzymes, respectively). These mediate the signalling of a number of cytokines and growth factors that are important for haematopoiesis and immune function.MF and PV are myeloproliferative neoplasms known to be associated with dysregulated JAK1 and JAK2 signalling. The basis for the dysregulation is believed to include high levels of circulating cytokines that activate the JAK-STAT pathway, gain-of-function mutations such as JAK2V617F, and silencing of negative regulatory mechanisms. MF patients exhibit dysregulated JAK signalling regardless of JAK2V617F mutation status. Activating mutations in JAK2 (V617F or exon 12) are found in >95% of PV patients.Rulicent 10 mg inhibits JAK-STAT signalling and cell proliferation of cytokine-dependent cellular models of haematological malignancies, as well as of Ba/F3 cells rendered cytokine-independent by expressing the JAK2V617F mutated protein, with IC 50 ranging from 80-320 nM.

Myclofibrosis: The recommended starting dose of Rulicent 10 mg is based on platelet count. A complete blood count (CBC) and platelet count must be performed before initiating therapy, every 2 to 4 weeks until doses are stabilized, and then as clinically indicated. Doses may be titrated based on safety and efficacy. Platelet count greater than 200 X 10 9 /L: Starting dose 20 mg orally twice daily. Platelet count 100 X 10 9 /L to 200 X 10 9 /L: Starting dose 15 mg orally twice daily. Platelet count 50 X 10 9 /L to less than 100 X 10 9 /L: Starting dose 5 mg orally twice daily. Polycythemia Vera: The recommended starting dose of Rulicent 10 mg is 10 mg twice daily. Doses may be titrated based on safety and efficacy. Consider decreasing the dose to 5 mg twice daily if the hemoglobin count 8 to less than 12g/dL and the platelet count 50 to less than 75 X 10 9 L.Acute Graft-Versus-Host Disease: The recommended dose of Rulicent 10 mg is 5 mg twice daily. Consider increasing the dose to 10 mg twice daily after at least 3 days of treatment if the ANC and platelet counts are not decreased by 50% or more relative to the first day of dosing with Rulicent 10 mg. Or as directed by the registered physician.

Rulicent 10 mg is to be taken orally, with or without food. If a dose is missed, the patient should not take an additional dose, but should take the next usual prescribed dose.

Fluconazole: Concomitant administration of Rulicent 10 mg with fluconazole greater than 200 mg daily may increase Rulicent 10 mg exposure due to inhibition of both the CYP3A4 and CYP2C9 metabolic pathways. Increased exposure may increase the risk of exposure-related adverse reactions. Avoid the concomitant use of Rulicent 10 mg with fluconazole doses of greater than 200 mg daily except in patients with acute GVHD.Strong CYP3A4 Inhibitors: Concomitant administration of Rulicent 10 mg with strong CYP3A4 inhibitors increases Rulicent 10 mg exposure. Increased exposure may increase the risk of exposure-related adverse reactions. Consider dose reduction when administering Rulicent 10 mg with strong CYP3A4 inhibitors. In patients with acute GVHD, reduce Rulicent 10 mg dose as recommended only when coadministered with ketoconazole, and monitor blood counts more frequently for toxicity and adjust the dose if necessary when coadministered with itraconazole.Strong CYP3A4 Inducers: Concomitant administration of Rulicent 10 mg with strong CYP3A4 inducers may decrease Rulicent 10 mg exposure. No dose adjustment is recommended; however, monitor patients frequently and adjust the Rulicent 10 mg dose based on safety and efficacy.

It is contraindicated in patients with a history of hypersensitivity to Rulicent 10 mg or any other components of this product.

The most common side effects are- Thrombocytopenia, Anemia and Neutropenia Risk of Infection, bruising, dizziness, headache Symptom Exacerbation Following Interruption or Discontinuation of treatment with Rulicent 10 mg Non-Melanoma Skin Cancer

Contraindicated in pregnancy & lactation. There are no data from the use of Rulicent 10 mg in pregnant women. Animal studies have shown that Rulicent 10 mg is embryotoxic and foetotoxic. Rulicent 10 mg must not be used during breast-feeding and breast-feeding should therefore be discontinued when treatment is started. It is unknown whether Rulicent 10 mg and/or its metabolites are excreted in human milk. A risk to the breast-fed child cannot be excluded. Available pharmacodynamic/toxicological data in animals have shown excretion of Rulicent 10 mg and its metabolites in milk Fertility: There are no human data on the effect of Rulicent 10 mg on fertility. In animal studies, no effect on fertility was observed.

Thrombocytopenia, Anemia And Neutropenia: Treatment with Rulicent 10 mg can cause thrombocytopenia, anemia and neutropenia. Manage thrombocytopenia by reducing the dose or temporarily interrupting Rulicent 10 mg. Platelet transfusions may be necessary.Patients developing anemia may require blood transfusions and/or dose modifications of Rulicent 10 mg.Severe neutropenia (ANC less than 0.5 X 109/L) was generally reversible by withholding Rulicent 10 mg until recovery.Perform a pre-treatment complete blood count (CBC) and monitor CBCs every 2 to 4 weeks until doses are stabilized, and then as clinically indicated.Risk of Infection: Serious bacterial, mycobacterial, fungal and viral infections have occurred. Delay starting therapy with Rulicent 10 mg until active serious infections have resolved. Observe patients receiving Rulicent 10 mg for signs and symptoms of infection and manage promptly.Tuberculosis: Tuberculosis infection has been reported in patients receiving Rulicent 10 mg. Observe patients receiving Rulicent 10 mg for signs and symptoms of active tuberculosis and manage promptly. Prior to initiating Rulicent 10 mg, patients should be evaluated for tuberculosis risk factors, and those at higher risk should be tested for latent infection. Risk factors include, but are not limited to, prior residence in or travel to countries with a high prevalence of tuberculosis, close contact with a person with active tuberculosis, and a history of active or latent tuberculosis where an adequate course of treatment cannot be confirmed. For patients with evidence of active or latent tuberculosis, consult a physician with expertise in the treatment of tuberculosis before starting Rulicent 10 mg. The decision to continue Rulicent 10 mg during treatment of active tuberculosis should be based on the overall risk-benefit determination.Progressive Multifocal Leukoencephalopathy: Progressive multifocal leukoencephalopathy (PML) has occurred with Rulicent 10 mg treatment. If PML is suspected, stop Rulicent 10 mg and evaluate.Herpes Zoster: Advise patients about early signs and symptoms of herpes zoster and to seek treatment as early as possible if suspected.Hepatitis B: Hepatitis B viral load (HBV-DNA titer) increases, with or without associated elevations in alanine aminotransferase and aspartate aminotransferase, have been reported in patients with chronic HBV infections taking Rulicent 10 mg. The effect of Rulicent 10 mg on viral replication in patients with chronic HBV infection is unknown. Patients with chronic HBV infection should be treated and monitored according to clinical guidelines.Symptom Exacerbation Following Interruption or Discontinuation Of Treatment With Rulicent 10 mg: Following discontinuation of Rulicent 10 mg, symptoms from myeloproliferative neoplasms may return to pretreatment levels over a period of approximately one week. Some patients with MF have experienced one or more of the following adverse events after discontinuing Rulicent 10 mg: fever, respiratory distress, hypotension, DIC, or multi organ failure. If one or more of these occur after discontinuation of, or while tapering the dose of Rulicent 10 mg, evaluate for and treat any intercurrent illness and consider restarting or increasing the dose of Rulicent 10 mg. Instruct patients not to interrupt or discontinue Rulicent 10 mg therapy without consulting their physician. When discontinuing or interrupting therapy with Rulicent 10 mg for reasons other than thrombocytopenia or neutropenia, consider tapering the dose of Rulicent 10 mg gradually rather than discontinuing abruptly.Non-Melanoma Skin Cancer: Non-melanoma skin cancers including basal cell, squamous cell, and Merkel cell carcinoma have occurred in patients treated with Rulicent 10 mg. Perform periodic skin examinations.Lipid Elevations: Treatment with Rulicent 10 mg has been associated with increases in lipid parameters including total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglycerides. The effect of these lipid parameter elevations on cardiovascular morbidity and mortality has not been determined in patients treated with Rulicent 10 mg. Assess lipid parameters approximately 8-12 weeks following initiation of Rulicent 10 mg therapy. Monitor and treat according to clinical guidelines for the management of hyperlipidemia.

There is no known antidote for overdoses with Rulicent 10 mg. Single doses up to 200 mg have been given with acceptable acute tolerability.

Pyrrolopyrimidines

Rulicent 10 mg, a kinase inhibitor, inhibits Janus Associated Kinases (JAKs) JAK1 and JAK2 which mediate the signaling of a number of cytokines and growth factors that are important for hematopoiesis and immune function. JAK signaling involves recruitment of STATs (signal transducers and activators of transcription) to cytokine receptors, activation and subsequent localization of STATs to the nucleus leading to modulation of gene expression. Myelofibrosis (MF) is a myeloproliferative neoplasm (MPN) known to be associated with dysregulated JAK1 and JAK2 signaling. Oral administration of Rulicent 10 mg prevented splenomegaly, preferentially decreased JAK2V617F mutant cells in the spleen and decreased circulating inflammatory cytokines (eg, TNF-α, IL-6).Absorption: Rulicent 10 mg is rapidly absorbed after oral Rulicent 10 mg administration with maximal plasma concentration (Cmax) achieved within 1 to 2 hours post-dose. Oral absorption of Rulicent 10 mg was estimated to be at least 95%. Distribution: The mean volume of distribution of Rulicent 10 mg at steady-state is 72 L in patient with MF and PV in myelofibrosis patients.Half-life: the mean half-life of Rulicent 10 mg & metabolites is approximately 5.8 hours. Elimination half-life: The mean elimination half-life of Rulicent 10 mg is approximately 3 hours AUC: Mean Rulicent 10 mg Cmax and total exposure (AUC) increased proportionally over a single dose range of 5 to 200 mg.The plasma protein binding: 97%, mostly to albumin. Metabolism: Rulicent 10 mg is metabolized by CYP3A4 and to a lesser extent by CYP2C9.Excretion: Following a single oral dose of radio labeled Rulicent 10 mg in healthy adult subjects, elimination was predominately through metabolism with 74% of radioactivity excreted in urine and 22% excretion via feces. Unchanged drug accounted for less than 1% of the excreted total radioactivity.

There are no adequate and well-controlled studies in pregnant women. It is not known whether Rulicent 10 mg is excreted in human milk. Because many drugs are excreted in human milk, breastfeeding should be discontinued during treatment with Rulicent 10 mg and for two weeks after the final dose.

Use in children: The safety and effectiveness of Rulicent 10 mg in pediatric patients have not been established.
