(Nasdaq: RIGL) today announced a peer-reviewed publication in Leukemia & Lymphoma on data from an analysis of the Phase 2 study evaluating REZLIDHIA® (olutasidenib), a potent, selective, oral, small-molecule inhibitor of mutant isocitrate dehydrogenase-1 (mIDH1)1, in patients with mIDH1 acute myeloid leukemia (AML) who were relapsed/refractory (R/R) to prior venetoclax-based regimens.\n\"Venetoclax in combination with a hypomethylating agent is currently standard treatment for patients with newly diagnosed AML who are unfit for intensive chemotherapy, including those with mIDH1. When this therapy fails, patients historically have had limited treatment options and poor prognoses,\" said Jorge E. Cortes, M.D., Director, Georgia Cancer Center, Cecil F. Whitaker Jr., GRA Eminent Scholar Chair in Cancer, and Phase 2 trial investigator. \"The findings from these analyses suggest that REZLIDHIA may provide an effective treatment for patients with AML following failure of venetoclax combination therapy. REZLIDHIA induced durable remissions consistent with those observed in the pivotal trial and had a favorable tolerability profile in this challenging to treat patient population, representing a valuable treatment option.\"\n\"These data support REZLIDHIA's efficacy and well-characterized safety profile in patients with mIDH1 R/R AML who had previously been treated with venetoclax combination regimens,\" said Raul Rodriguez, Rigel's president and CEO. \"These analyses are important because they provide valuable insights into the potential benefit of REZLIDHIA in different segments of the mIDH1 R/R AML patient population.\"\nKey points from the paper are summarized below:\n\nOlutasidenib alone or in combination with azacitidine demonstrated potential efficacy in patients with AML following failure of venetoclax combination therapy\nOf the 18 patients with prior venetoclax treatment, 10 were relapsed, 6 were refractory, and 2 had complete remission with incomplete hematologic recovery (CRi) to a venetoclax combination\nOf the 16 R/R patients, 7 (43.8%) achieved a composite complete remission (CRc), 4 (25%) achieved complete remission (CR), and 1 (6.3%) achieved CR with partial hematologic recovery (CRh). Both patients with CRi at study entry achieved CR\nMedian time to CRc was 1.9 months (range 1-2.8). As of the data cut-off (June 18, 2021), median duration of CRc was not reached (range, 1.2-NR, ongoing at 30.4+ months)\nRed blood cell and platelet transfusion independence was achieved in 2/12 (17%) and 2/7 (29%) transfusion-dependent R/R patients at baseline, respectively\nSafety was consistent with the overall profile of olutasidenib\n\nThe paper, titled \"Olutasidenib in post-venetoclax patients with mutant isocitrate dehydrogenase 1 (mIDH1) acute myeloid leukemia (AML),\" was published online in Leukemia & Lymphoma and can be accessed here.\nAbout AMLAcute myeloid leukemia (AML) is a rapidly progressing cancer of the blood and bone marrow that affects myeloid cells, which normally develop into various types of mature blood cells. AML occurs primarily in adults and accounts for about 1 percent of all adult cancers. The American Cancer Society estimates that there will be about 20,800 new cases in the United States, most in adults, in 2024.2\nRelapsed AML affects about half of all patients who, following treatment and remission, experience a return of leukemia cells in the bone marrow.3 Refractory AML, which affects between 10 and 40 percent of newly diagnosed patients, occurs when a patient fails to achieve remission even after intensive treatment.4 Quality of life declines for patients with each successive line of treatment for AML, and well-tolerated treatments in relapsed or refractory disease remain an unmet need.\nAbout REZLIDHIA®\nINDICATIONREZLIDHIA is indicated for the treatment of adult patients with relapsed or refractory acute myeloid leukemia (AML) with a susceptible isocitrate dehydrogenase-1 (IDH1) mutation as detected by an FDA-approved test.\nIMPORTANT SAFETY INFORMATION \n\n\n\n\nWARNING: DIFFERENTIATION SYNDROME Differentiation syndrome, which can be fatal, can occur with REZLIDHIA treatment. Symptoms may include dyspnea, pulmonary infiltrates/pleuropericardial effusion, kidney injury, hypotension, fever, and weight gain. If differentiation syndrome is suspected, withhold REZLIDHIA and initiate treatment with corticosteroids and hemodynamic monitoring until symptom resolution. \n\n\n\n\nWARNINGS AND PRECAUTIONS\nDifferentiation SyndromeREZLIDHIA can cause differentiation syndrome. In the clinical trial of REZLIDHIA in patients with relapsed or refractory AML, differentiation syndrome occurred in 16% of patients, with grade 3 or 4 differentiation syndrome occurring in 8% of patients treated, and fatalities in 1% of patients. Differentiation syndrome is associated with rapid proliferation and differentiation of myeloid cells and may be life-threatening or fatal. Symptoms of differentiation syndrome in patients treated with REZLIDHIA included leukocytosis, dyspnea, pulmonary infiltrates/pleuropericardial effusion, kidney injury, fever, edema, pyrexia, and weight gain. Of the 25 patients who experienced differentiation syndrome, 19 (76%) recovered after treatment or after dose interruption of REZLIDHIA. Differentiation syndrome occurred as early as 1 day and up to 18 months after REZLIDHIA initiation and has been observed with or without concomitant leukocytosis.\nIf differentiation syndrome is suspected, temporarily withhold REZLIDHIA and initiate systemic corticosteroids (e.g., dexamethasone 10 mg IV every 12 hours) for a minimum of 3 days and until resolution of signs and symptoms. If concomitant leukocytosis is observed, initiate treatment with hydroxyurea, as clinically indicated. Taper corticosteroids and hydroxyurea after resolution of symptoms. Differentiation syndrome may recur with premature discontinuation of corticosteroids and/or hydroxyurea treatment. Institute supportive measures and hemodynamic monitoring until improvement; withhold dose of REZLIDHIA and consider dose reduction based on recurrence.\nHepatotoxicityREZLIDHIA can cause hepatotoxicity, presenting as increased alanine aminotransferase (ALT), increased aspartate aminotransferase (AST), increased blood alkaline phosphatase, and/or elevated bilirubin. Of 153 patients with relapsed or refractory AML who received REZLIDHIA, hepatotoxicity occurred in 23% of patients; 13% experienced grade 3 or 4 hepatotoxicity. One patient treated with REZLIDHIA in combination with azacitidine in the clinical trial, a combination for which REZLIDHIA is not indicated, died from complications of drug-induced liver injury. The median time to onset of hepatotoxicity in patients with relapsed or refractory AML treated with REZLIDHIA was 1.2 months (range: 1 day to 17.5 months) after REZLIDHIA initiation, and the median time to resolution was 12 days (range: 1 day to 17 months). The most common hepatotoxicities were elevations of ALT, AST, blood alkaline phosphatase, and blood bilirubin. Monitor patients frequently for clinical symptoms of hepatic dysfunction such as fatigue, anorexia, right upper abdominal discomfort, dark urine, or jaundice. Obtain baseline liver function tests prior to initiation of REZLIDHIA, at least once weekly for the first two months, once every other week for the third month, once in the fourth month, and once every other month for the duration of therapy. If hepatic dysfunction occurs, withhold, reduce, or permanently discontinue REZLIDHIA based on recurrence/severity.\nADVERSE REACTIONSThe most common (≥20%) adverse reactions, including laboratory abnormalities, were aspartate aminotransferase increased, alanine aminotransferase increased, potassium decreased, sodium decreased, alkaline phosphatase increased, nausea, creatinine increased, fatigue/malaise, arthralgia, constipation, lymphocytes increased, bilirubin increased, leukocytosis, uric acid increased, dyspnea, pyrexia, rash, lipase increased, mucositis, diarrhea and transaminitis.\nDRUG INTERACTIONS\n\nAvoid concomitant use of REZLIDHIA with strong or moderate CYP3A inducers.\nAvoid concomitant use of REZLIDHIA with sensitive CYP3A substrates unless otherwise instructed in the substrates prescribing information. If concomitant use is unavoidable, monitor patients for loss of therapeutic effect of these drugs.\n\nLACTATIONAdvise women not to breastfeed during treatment with REZLIDHIA and for 2 weeks after the last dose.\nGERIATRIC USENo overall differences in effectiveness were observed between patients 65 years and older and younger patients. Compared to patients younger than 65 years of age, an increase in incidence of hepatotoxicity and hypertension was observed in patients ≥65 years of age.\nHEPATIC IMPAIRMENTIn patients with mild or moderate hepatic impairment, closely monitor for increased probability of differentiation syndrome.\nClick here for Full Prescribing Information, including Boxed WARNING.\nTo report side effects of prescription drugs to the FDA, visit www.fda.gov/medwatch or call 1-800-FDA-1088 (800-332-1088).\nREZLIDHIA is a registered trademark of Rigel Pharmaceuticals, Inc.\nAbout RigelRigel Pharmaceuticals, Inc.
