New analysis of the pivotal Phase 3 SOLOIST-WHF trial demonstrates INPEFA cost-effectiveness Findings consistent with another study recently published in the Journal of Comparative Effectiveness Research THE WOODLANDS, Texas, June 18, 2024 (GLOBE NEWSWIRE) -- Lexicon Pharmaceuticals, Inc. (Nasdaq: LXRX) today announced that the peer-reviewed Journal of the American College of Cardiology: Heart Failure has published a research paper concluding that INPEFA® (sotagliflozin) is cost-effective for people with diabetes and recent worsening heart failure using commonly accepted willingness-to-pay thresholds. “Our research team believes that this study is an important contribution to the economic evaluation of sotagliflozin, a novel SGLT inhibitor, from the perspective of the U.S. healthcare system. Our results demonstrated that in people with diabetes and recent worsening heart failure, sotagliflozin is cost-effective at commonly accepted willingness-to-pay thresholds,” said William S. Weintraub, MD, MACC, FAHA, FESC, director of Population Health Research at MedStar Health Research Institute, and the lead author of the research paper. The analysis was conducted from a U.S. healthcare sector perspective, in accordance with Consolidated Health Economic Evaluation Reporting Standards. Results from this study showed that lifetime quality-adjusted life-years (QALYs) were 4.43 and 4.04 in the INPEFA and placebo groups, respectively. In another study, “Cost-effectiveness of sotagliflozin for the treatment of patients with diabetes and recent worsening heart failure,” recently published in the Journal of Comparative Effectiveness Research, the research team used published real-world data to derive baseline event frequencies and SOLOIST-WHF study data to estimate the efficacy of INPEFA. According to the research results, the use of INPEFA led to a net gain in QALYs of 0.425 for INPEFA versus standard of care. The investigators concluded that INPEFA is a cost-effective addition to standard of care for patients hospitalized with heart failure and comorbid diabetes. “The data published in these two peer-reviewed journals reinforce our position that in addition to providing meaningful clinical benefits to heart failure patients, INPEFA provides significant financial value for payors and the U.S. healthcare system,” said Craig Granowitz, M.D., Ph.D., Lexicon’s senior vice president and chief medical officer.

Lexicon has commercially launched one of these medicines, INPEFA® (sotagliflozin) in the United States, and has a pipeline of other promising drug candidates in discovery and clinical and preclinical development in neuropathic pain, diabetes and metabolism and other indications. For additional information, please visit www.lexpharma.com.  About INPEFA® (sotagliflozin) Discovered using Lexicon’s unique approach to gene science, INPEFA® (sotagliflozin) is an oral inhibitor of two proteins responsible for glucose regulation known as sodium-glucose cotransporter types 2 and 1 (SGLT2 and SGLT1). SGLT2 is responsible for glucose and sodium reabsorption by the kidney and SGLT1 is responsible for glucose and sodium absorption in the gastrointestinal tract. Sotagliflozin has been studied in multiple patient populations encompassing heart failure, diabetes, and chronic kidney disease in clinical studies involving approximately 20,000 patients. INDICATION INPEFA is indicated to reduce the risk of cardiovascular death, hospitalization for heart failure, and urgent heart failure visit in adults with: heart failure or type 2 diabetes mellitus, chronic kidney disease, and other cardiovascular risk factors IMPORTANT SAFETY INFORMATION Dosing: Assess renal function and volume status and, if necessary, correct volume depletion prior to initiation of INPEFA. INPEFA dosing for patients with decompensated heart failure may begin when patients are hemodynamically stable, including when hospitalized or immediately upon discharge. Contraindications: INPEFA is contraindicated in patients with hypersensitivity to INPEFA or any of its components. Ketoacidosis: INPEFA increases the risk of ketoacidosis in patients with type 1 diabetes mellitus (T1DM).  Type 2 diabetes Mellitus (T2DM) and pancreatic disorders are also risk factors.  The risk of ketoacidosis may be greater with higher doses.  There have been postmarketing reports of fatal events of ketoacidosis in patients with type 2 diabetes using sodium glucose transporter 2 (SGLT2) inhibitors.  Before initiating INPEFA, assess risk factors for ketoacidosis. Consider ketone monitoring in patients with T1DM and consider ketone monitoring in others at risk for ketoacidosis and educate patients on the signs/symptoms of ketoacidosis.  Patients receiving INPEFA may require monitoring and temporary discontinuation of therapy in clinical situations known to predispose to ketoacidosis.  INPEFA is not indicated for glycemic control. Assess patients who present with signs and symptoms of metabolic acidosis or ketoacidosis, regardless of blood glucose level.  If suspected, discontinue INPEFA, evaluate, and treat promptly.  Monitor patients for resolution of ketoacidosis before restarting INPEFA. Volume Depletion: INPEFA can cause intravascular volume depletion which may sometimes manifest as symptomatic hypotension or acute transient changes in creatinine.  There have been post-marketing reports of acute kidney injury, some requiring hospitalization and dialysis, in patients with type 2 diabetes mellitus receiving SGLT2 inhibitors.  Patients with impaired renal function (eGFR < 60 mL/min/1.73 m2), elderly patients, or patients on loop diuretics may be at increased risk for volume depletion or hypotension.  Before initiating INPEFA in patients with one or more of these characteristics, assess volume status and renal function, and monitor for signs and symptoms of hypotension during therapy. Urosepsis and Pyelonephritis: Treatment with SGLT2 inhibitors, including INPEFA, increases the risk for urinary tract infections.  Serious urinary tract infections including urosepsis and pyelonephritis requiring hospitalization have been reported. Evaluate patients for signs and symptoms of urinary tract infections and treat promptly. Hypoglycemia with Concomitant Use with Insulin and Insulin Secretagogues: Insulin and insulin secretagogues are known to cause hypoglycemia.  INPEFA may increase the risk of hypoglycemia when combined with insulin or an insulin secretagogue.  Therefore, a lower dose of insulin or insulin secretagogue may be required to minimize the risk of hypoglycemia when used with INPEFA. Necrotizing Fasciitis of the Perineum (Fournier’s Gangrene): Reports of Fournier’s Gangrene, a rare but serious and life-threatening necrotizing infection requiring urgent surgical intervention, have been identified in post-marketing surveillance in patients with diabetes mellitus receiving SGLT2 inhibitors.  Assess patients who present with pain, tenderness, erythema, or swelling in the genital or perineal area, along with fever or malaise. If suspected, start treatment immediately with broad-spectrum antibiotics and, if necessary, surgical debridement.  Discontinue INPEFA, closely monitor patient signs and symptoms, and provide appropriate alternative therapy for heart failure. Genital Mycotic Infections: INPEFA increases the risk of genital mycotic infections.  Monitor and treat as appropriate. Urinary Glucose Test and 1,5-anhydroglucitol (1,5-AG) Assay: these are not reliable for patients taking SGLT2 inhibitors.  Use alternative testing methods to monitor glucose levels.  Common Adverse Reactions: the most commonly reported adverse reactions (incidence ≥ 5%) were urinary tract infection, volume depletion, diarrhea, and hypoglycemia. Drug Interactions: Digoxin: Monitor patients appropriately as there is an increase in the exposure of digoxin when coadministered with INPEFA 400 mg.Uridine 5'-diphospho-glucuronosyltransferase (UGT) Inducer: The coadministration of rifampicin, an inducer of UGTs, with sotagliflozin resulted in a decrease in the exposure of sotagliflozin.  Lithium: Concomitant use of an SGLT2 inhibitor with lithium may decrease serum lithium concentrations.  Monitor serum lithium concentration more frequently during INPEFA initiation and with dosage changes. Use in Specific Populations: Pregnancy and Lactation: INPEFA is not recommended during the second and third trimesters of pregnancy, nor while breastfeeding. Geriatric Use: No INPEFA dosage change is recommended based on age.  No overall differences in efficacy were detected between these patients and younger patients, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.  Elderly patients may be at increased risk for volume depletion adverse reactions, including hypotension. Renal Impairment: INPEFA was evaluated in patients with chronic kidney disease (eGFR 25 to 60 mL/min/1.73 m2) and in patients with heart failure with eGFR < 60 mL/min/1.73 m2.  The safety profile of INPEFA across eGFR subgroups in these studies was consistent with the known safety profile.  There was an increase in volume-related adverse events (e.g., hypotension, dizziness) in patients with eGFR < 30 mL/min/1.73m2  relative to the overall safety population.  Efficacy and safety studies with INPEFA did not enroll patients with an eGFR less than 25 mL/min/1.73 m2 or on dialysis.  After starting therapy in the studies, patients were discontinued if eGFR fell below 15 mL/min/1.73 m2 or were initiated on chronic dialysis. Hepatic Impairment: INPEFA is not recommended in patients with moderate or severe hepatic impairment.

In Study 502, lumateperone 42 mg achieved statistically significant and clinically meaningful results in both the primary and the key secondary endpoints Lumateperone 42 mg met the primary endpoint of change from baseline at Week 6 on the Montgomery-Åsberg Depression Rating Scale (MADRS) total score versus placebo (4.5 point reduction v. placebo; p<0.0001; Cohen’s d effect size (ES)=0.56) Lumateperone 42 mg also met the key secondary endpoint of change from baseline at Week 6 on the Clinical Global Impression Scale for Severity of Illness (CGI-S) (p<0.0001; ES=0.51) Statistically significant efficacy was also seen in the Quick Inventory of Depressive Symptomatology Self-Report (QIDS-SR) scale, a patient self-reported measure of symptom severity of depression (p<0.0001) Favorable safety and tolerability pro consistent with prior lumateperone trials Supplemental NDA (sNDA) submission for the adjunctive treatment of major depressive disorder (MDD) anticipated in the second half of 2024 Conference call scheduled today at 8:30 a.m. ET NEW YORK, June 18, 2024 (GLOBE NEWSWIRE) -- Intra-Cellular Therapies, Inc. (Nasdaq: ITCI), a biopharmaceutical company focused on the development and commercialization of therapeutics for central nervous system (CNS) disorders, today announced positive topline results from Study 502 evaluating lumateperone 42 mg as an adjunctive therapy to antidepressants for the treatment of MDD. This trial, in conjunction with our previously reported positive Phase 3 study, Study 501, forms the basis for our lumateperone sNDA for the adjunctive treatment of MDD. We expect to submit this sNDA to the U.S. Food and Drug Administration (FDA) in the second half of 2024. “We are confident that the efficacy results from Studies 501 and 502, along with the favorable safety and tolerability profiles from these studies, will make lumateperone a drug of choice for patients suffering with MDD who are having an inadequate response to antidepressant therapy,” said Dr. Sharon Mates, Chairman and CEO of Intra-Cellular Therapies. “We are very pleased with the robust efficacy results from Study 502 which are consistent with the compelling results from Study 501. These results, further support our vision for CAPLYTA to become a leading option for patients and providers across mood disorders.” Lumateperone 42 mg given once daily as adjunctive therapy to antidepressants met the primary endpoint in Study 502 by demonstrating a statistically significant and clinically meaningful reduction in the MADRS total score compared to placebo at Week 6. In the modified intent-to-treat (mITT) study population, the least squares (LS) mean reduction from baseline for lumateperone 42 mg was 14.7 points, versus 10.2 points for placebo (LS mean difference = -4.5 points; p<0.0001; ES= 0.56). Numerical improvement versus placebo on the MADRS total score was seen as early as Week 1 (p=0.0504) and statistically significant separation starting at Week 2 and maintained throughout the study. Lumateperone 42 mg also met the key secondary endpoint in the study by demonstrating a statistically significant and clinically meaningful reduction in the CGI-S score compared to placebo at Week 6 (p<0.0001; ES= 0.51). Statistically significant separation on the CGI-S versus placebo was observed starting at Week 3 and maintained throughout the study. In this study, lumateperone 42 mg robustly improved depressive symptoms as reported by patients as measured by the Quick Inventory of Depressive Symptomatology Self Report (QIDS-SR-16) (p<0.0001). The QIDS-SR-16 is a 16-item patient-rated scale of symptom severity in depression. It assesses nine key symptoms of depression: insomnia/hypersomnia, low mood, appetite/weight changes, impaired self-perception, concentration difficulties, loss of interest/pleasure, suicidal ideation, psychomotor agitation and fatigue. Lumateperone was generally safe and well-tolerated in this study. The most common adverse events (≥5% and greater than twice placebo) were dizziness, somnolence, dry mouth, nausea, diarrhea and fatigue. Adverse events were mostly mild to moderate and resolved within the course of the study. These adverse events were generally similar to those seen in prior studies of lumateperone as a treatment for MDD, bipolar depression and schizophrenia. In this study, 480 patients were randomized (1:1) to lumateperone 42 mg plus antidepressant or placebo plus antidepressant to evaluate the efficacy and safety of lumateperone as an adjunctive treatment to antidepressants in patients with MDD. The baseline MADRS total score was 30.8 for lumateperone 42 mg and 31.5 for placebo. “MDD is the leading cause of disability in the world, where about two-thirds of patients fail to achieve remission with first-line treatment,” said Dr. Suresh Durgam, Executive Vice President, Chief Medical Officer of Intra-Cellular Therapies. “In both pivotal registrational studies, Study 501 and Study 502, lumateperone demonstrated a robust effect as an adjunctive treatment to antidepressants in patients with MDD who had inadequate response to antidepressant therapy. The consistent efficacy, safety and tolerability pro lumateperone has the potential to be a compelling treatment option for MDD.” About the Lumateperone Adjunctive MDD Program Studies 501 and 502 evaluated lumateperone 42 mg as an adjunctive treatment to antidepressants in patients with MDD who had inadequate response to antidepressant therapy. These are both multicenter, randomized, double-blind, placebo-controlled, parallel-group, fixed-dose studies conducted globally in patients with a primary diagnosis of MDD according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria who have had an inadequate response to ongoing anti-depressant therapy. Eligible patients had a minimum MADRS total score of 24, a minimum CGI-S score of 4 and an inadequate response to one or two SSRI/SNRIs (less than 50% improvement) following monotherapy treatment for at least 6 weeks duration. The primary endpoint results from Studies 501 and 502 are as follows: Primary Endpoint: Change from baseline vs. placebo on the MADRS Total Score at Week 6 (mITT study population) Least Squares (LS) Mean Reduction vs. Baseline1 LS mean difference1 p value Cohen's d effect size STUDY 501 Lumateperone 42 mg +ADT 14.7 -4.9 <0.0001 0.61 placebo +ADT 9.8 STUDY 502 Lumateperone 42 mg+ADT 14.7 -4.5 <0.0001 0.56 placebo +ADT 10.2 1 rounded to nearest tenth; ADT: Antidepressant therapy In the pooled safety data of Studies 501 and 502, the most common adverse events (≥5% and greater than twice placebo) with lumateperone versus placebo were: dizziness (16.6% v. 5.0%), dry mouth (12.6% v. 3.3%), somnolence (12.2% v. 2.3%), nausea (8.5% v. 4.0%) and fatigue (7.2% v. 1.2%). About Major Depressive Disorder Major Depressive Disorder (MDD) is a common mood disorder in the U.S. affecting an estimated 21 million adults each year. MDD represents the primary cause of disability in the world. Symptoms include sadness, hopelessness, helplessness, feelings of guilt, irritability, loss of interest in formerly pleasurable activities, cognitive impairment, disturbed sleep patterns, and suicide ideation or behavior. It can cause severe functional impairment, adversely affecting interpersonal relationships, and may impact quality of life. Approximately two-thirds of patients with depression fail to achieve remission with first-line treatment.

CAPLYTA® (lumateperone) is indicated in adults for the treatment of schizophrenia and for the treatment of depressive episodes associated with bipolar I or II disorder (bipolar depression) as monotherapy and as adjunctive therapy with lithium or valproate. Important Safety Information Boxed Warnings: Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. CAPLYTA is not approved for the treatment of patients with dementia-related psychosis. Antidepressants increased the risk of suicidal thoughts and behaviors in pediatric and young adults in short-term studies. All antidepressant-treated patients should be closely monitored for clinical worsening, and for emergence of suicidal thoughts and behaviors. The safety and effectiveness of CAPLYTA have not been established in pediatric patients. Contraindications: CAPLYTA is contraindicated in patients with known hypersensitivity to lumateperone or any components of CAPLYTA. Reactions have included pruritus, rash (e.g., allergic dermatitis, papular rash, and generalized rash), and urticaria. Warnings & Precautions: Antipsychotic drugs have been reported to cause: Cerebrovascular Adverse Reactions in Elderly Patients with Dementia-Related Psychosis, including stroke and transient ischemic attack. See Boxed Warning above. Neuroleptic Malignant Syndrome (NMS), which is a potentially fatal reaction. Signs and symptoms include: high fever, stiff muscles, confusion, changes in breathing, heart rate, and blood pressure, elevated creatinine phosphokinase, myoglobinuria (and/or rhabdomyolysis), and acute renal failure. Patients who experience signs and symptoms of NMS should immediately contact their doctor or go to the emergency room. Tardive Dyskinesia, a syndrome of uncontrolled body movements in the face, tongue, or other body parts, which may increase with duration of treatment and total cumulative dose. TD may not go away, even if CAPLYTA is discontinued. It can also occur after CAPLYTA is discontinued. Metabolic Changes, including hyperglycemia, diabetes mellitus, dyslipidemia, and weight gain. Hyperglycemia, in some cases extreme and associated with ketoacidosis, hyperosmolar coma or death, has been reported in patients treated with antipsychotics. Measure weight and assess fasting plasma glucose and lipids when initiating CAPLYTA and monitor periodically during long-term treatment. Leukopenia, Neutropenia, and Agranulocytosis (including fatal cases). Complete blood counts should be performed in patients with pre-existing low white blood cell count (WBC) or history of leukopenia or neutropenia. CAPLYTA should be discontinued if clinically significant decline in WBC occurs in absence of other causative factors. Decreased Blood Pressure & Dizziness. Patients may feel lightheaded, dizzy or faint when they rise too quickly from a sitting or lying position (orthostatic hypotension). Heart rate and blood pressure should be monitored and patients should be warned with known cardiovascular or cerebrovascular disease. Orthostatic vital signs should be monitored in patients who are vulnerable to hypotension. Falls. CAPLYTA may cause sleepiness or dizziness and can slow thinking and motor skills, which may lead to falls and, consequently, fractures and other injuries. Patients should be assessed for risk when using CAPLYTA. Seizures. CAPLYTA should be used cautiously in patients with a history of seizures or with conditions that lower seizure threshold. Potential for Cognitive and Motor Impairment. Patients should use caution when operating machinery or motor vehicles until they know how CAPLYTA affects them. Body Temperature Dysregulation. CAPLYTA should be used with caution in patients who may experience conditions that may increase core body temperature such as strenuous exercise, extreme heat, dehydration, or concomitant anticholinergics. Dysphagia. CAPLYTA should be used with caution in patients at risk for aspiration. Drug Interactions: CAPLYTA should not be used with CYP3A4 inducers. Dose reduction is recommended for concomitant use with strong CYP3A4 inhibitors or moderate CYP3A4 inhibitors. Special Populations: Newborn infants exposed to antipsychotic drugs during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms following delivery. Dose reduction is recommended for patients with moderate or severe hepatic impairment. Adverse Reactions: The most common adverse reactions in clinical trials with CAPLYTA vs. placebo were somnolence/sedation, dizziness, nausea, and dry mouth. CAPLYTA is available in 10.5 mg, 21 mg, and 42 mg capsules. Please click here to see full Prescribing Information including Boxed Warning.
