New Four-Year Sotyktu (deucravacitinib) Data Demonstrate Durable Response Rates and Consistent Safety in Moderate-to-Severe Plaque Psoriasis

Business Wire 16-May-2024 10:26 AM

Following four years of continuous Sotyktu treatment, clinical response was maintained in more than seven out of 10 patients for Psoriasis Area and Severity Index (PASI) 75 in the POETYK PSO long-term extension trial

No new safety signals observed at Year 4 in the POETYK PSO long-term extension trial, consistent with the established Sotyktu safety profile

Bristol Myers Squibb (NYSE:BMY) today announced new four-year results from the POETYK PSO long-term extension (LTE) trial of Sotyktu (deucravacitinib) treatment in adult patients with moderate-to-severe plaque psoriasis. After four years of continuous treatment, Week 208 responses for Psoriasis Area and Severity Index (PASI) 75 and 90 were 71.7% and 47.5%, respectively, and 57.2% for static Physician's Global Assessment (sPGA) 0/1 (clear/almost clear), using modified nonresponder imputation (mNRI). The safety profile of Sotyktu at Year 4 remained consistent with the established safety profile, with no new safety signals identified.

These data were presented at the European Academy of Dermatology and Venereology (EADV) Spring Symposium in St. Julian's, Malta taking place May 16-18, 2024.

"These four-year results further validate the safety profile, efficacy and key role of once-daily Sotyktu, the first and only TYK2 inhibitor available, for adults with moderate-to-severe plaque psoriasis," said April Armstrong, MD, MPH, clinical investigator in the POETYK PSO clinical trial program and professor and chief of dermatology at the University of California, Los Angeles. "Many patients and their healthcare providers are looking for an efficacious, convenient oral treatment option that provides sustained relief from this chronic disease, allowing patients to prioritize other aspects of their daily lives. These findings further reinforce that we are able to offer a potential oral standard of care to meet patients' needs."

The efficacy analysis included 513 patients who received continuous Sotyktu treatment from Day 1 in the pivotal POETYK PSO-1 and POETYK PSO-2 trials and transitioned to the POETYK PSO-LTE trial. Clinical efficacy outcomes were maintained in patients who were continuously treated with Sotyktu from baseline through Year 4, with sustained response rates for PASI 75 of 71.7% at Year 4 (Year 1, 72.0%; Year 3, 73.8%), PASI 90 of 47.5% (Year 1, 45.6%; Year 3, 49.0%) and sPGA 0/1 of 57.2% (Year 1, 57.7%; Year 3, 55.2%).  

The safety analysis included 1,519 patients who received at least one dose of Sotyktu across POETYK PSO-1, POETYK PSO-2 and POETYK PSO-LTE. Cumulative exposure from parent trial randomization was 4,392.8 patient-years (PYs) for the safety analyses. With increased exposure to Sotyktu, the exposure-adjusted incidence rates (EAIRs)/100 PYs at Year 4 decreased or remained the same as those at Year 1 for adverse events (AEs) (Year 1, 229.2; Year 4, 131.7), serious AEs (Year 1, 5.7; Year 4, 5.0), discontinuation due to AEs (Year 1, 4.4; Year 4, 2.2), herpes zoster (Year 1, 0.8; Year 4, 0.6), malignancies (Year 1, 1.0; Year 4, 0.9), major adverse cardiovascular events (Year 1, 0.3; Year 4, 0.3), venous thromboembolism (Year 1, 0.2; Year 4, 0.1) and deaths (Year 1, 0.2; Year 4, 0.3). EAIRs/100 PYs were calculated as the number of patients with an AE over the total exposure time for all patients at risk (time to an initial AE occurrence for patients with an AE and time of total exposure for patients without an AE). 

"The data from our robust POETYK PSO clinical program continue to reinforce the potential of the first-in-class Sotyktu as an oral standard of care for individuals living with moderate-to-severe plaque psoriasis," said Alyssa Johnsen, MD, PhD, senior vice president and head of clinical development, Immunology, Cardiovascular and Neuroscience, Bristol Myers Squibb. "Our leadership in TYK2 innovation highlights our transformational science that is advancing care for immune-mediated diseases."

Bristol Myers Squibb thanks the patients and investigators involved in the POETYK PSO clinical trial program.

About the POETYK PSO Clinical Trial Program

PrOgram to Evaluate the efficacy and safety of Sotyktu (deucravacitinib), a selective TYK2 inhibitor (POETYK) PSO-1 (NCT03624127) and POETYK PSO-2 (NCT03611751) were global Phase 3 studies designed to evaluate the efficacy of Sotyktu compared to placebo and Otezla® (apremilast), and the safety of Sotyktu, in patients with moderate-to-severe plaque psoriasis. Both POETYK PSO-1, which enrolled 666 patients, and POETYK PSO-2, which enrolled 1,020 patients, were multicenter, randomized, double-blind trials that evaluated Sotyktu (6 mg once daily) compared to placebo and Otezla (30 mg twice daily). POETYK PSO-2 included a randomized withdrawal and retreatment period after Week 24.

The co-primary endpoints of both POETYK PSO-1 and POETYK PSO-2 were the percentage of patients who achieved Psoriasis Area and Severity Index (PASI) 75 response and those who achieved static Physician's Global Assessment (sPGA) score of 0 or 1 (clear/almost clear) at Week 16 versus placebo. Key secondary endpoints of the trials included the percentage of patients who achieved PASI 75 and sPGA 0/1 compared to Otezla at Week 16 and other measures evaluating Sotyktu versus placebo and Otezla.

Across both clinical trials and timepoints, significantly more Sotyktu-treated patients achieved a sPGA score of 0/1, PASI 75 response and PASI 90 response. Responses persisted through Week 52, as 82% (187/228) of patients who achieved PASI 75 with Sotyktu at Week 24 maintained their response at Week 52 in POETYK PSO-1. In POETYK PSO-2, 80% (119/148) of patients who continued Sotyktu maintained PASI 75 response compared to 31% (47/150) of patients who were withdrawn from Sotyktu.

Following the 52-week POETYK PSO-1 and POETYK PSO-2 trials, patients could enroll in the ongoing POETYK PSO long-term extension (LTE) trial (NCT04036435) and receive open-label Sotyktu 6 mg once-daily. In the LTE trial, 1,221 patients were enrolled and received at least one dose of Sotyktu. Efficacy was analyzed utilizing treatment failure rules (TFR) method of imputation, along with sensitivity analyses using modified non-responder imputation and as-observed analysis, which have been used in similar analyses with other agents.

In addition to POETYK PSO-1, POETYK PSO-2 and POETYK PSO-LTE, Bristol Myers Squibb has evaluated Sotyktu in two other Phase 3 studies in psoriasis: POETYK PSO-3 (NCT04167462) and POETYK PSO-4 (NCT03924427).

About Psoriasis

Psoriasis is a widely prevalent, chronic, systemic immune-mediated disease that substantially impairs patients' physical health, quality of life and work productivity. Psoriasis is a serious global problem, with at least 100 million people worldwide impacted by some form of the disease, including around 14 million people in Europe and approximately 7.5 million people in the United States. Nearly one-quarter of people with psoriasis have cases that are considered moderate-to-severe. Up to 90 percent of patients with psoriasis have psoriasis vulgaris, or plaque psoriasis, which is characterized by distinct round or oval plaques typically covered by silvery-white scales. Despite the availability of effective systemic therapy, many patients with moderate-to-severe plaque psoriasis remain undertreated or even untreated and are dissatisfied with current treatments. People with psoriasis report an impact on their emotional well-being, straining both personal and professional relationships and causing a reduced quality of life. Psoriasis is associated with multiple comorbidities that may impact patients' well-being, including psoriatic arthritis, cardiovascular disease, metabolic syndrome, obesity, diabetes, inflammatory bowel disease and depression.

About Sotyktu (deucravacitinib)

Sotyktu (deucravacitinib) is an oral, selective, allosteric tyrosine kinase 2 (TYK2) inhibitor with a unique mechanism of action, representing a new class of small molecules. It is the first selective TYK2 inhibitor in clinical studies across multiple immune-mediated diseases. Bristol Myers Squibb scientists designed Sotyktu to selectively target TYK2, thereby inhibiting signaling of interleukin (IL)-23, IL-12 and Type 1 interferons (IFN), key cytokines involved in the pathogenesis of multiple immune-mediated diseases. Sotyktu achieves a high degree of selectivity by binding to the regulatory domain of TYK2, resulting in allosteric inhibition of TYK2 and its downstream functions. Sotyktu selectively inhibits TYK2 at physiologically relevant concentrations. At therapeutic doses, Sotyktu does not inhibit JAK1, JAK2 or JAK3.

By building partnerships with researchers, patients and caregivers to deliver innovative treatments, Bristol Myers Squibb strives to elevate patient care to new standards and deliver what matters most – the promise of living a better life.

SOTYKTU U.S. INDICATION

SOTYKTU™ (deucravacitinib) is indicated for the treatment of moderate-to-severe plaque psoriasis in adults who are candidates for systemic therapy or phototherapy.

Limitations of Use:

SOTYKTU is not recommended for use in combination with other potent immunosuppressants.

IMPORTANT SAFETY INFORMATION

CONTRAINDICATIONS

SOTYKTU is contraindicated in patients with a history of hypersensitivity reaction to deucravacitinib or to any of the excipients in SOTYKTU.

WARNINGS AND PRECAUTIONS

Hypersensitivity: Hypersensitivity reactions such as angioedema have been reported. If a clinically significant hypersensitivity reaction occurs, institute appropriate therapy and discontinue SOTYKTU.

Infections: SOTYKTU may increase the risk of infections. Serious infections have been reported in patients with psoriasis who received SOTYKTU. The most common serious infections reported with SOTYKTU included pneumonia and COVID-19. Avoid use of SOTYKTU in patients with an active or serious infection. Consider the risks and benefits of treatment prior to initiating SOTYKTU in patients:

  • with chronic or recurrent infection
  • who have been exposed to tuberculosis
  • with a history of a serious or an opportunistic infection
  • with underlying conditions that may predispose them to infection.

Closely monitor patients for the development of signs and symptoms of infection during and after treatment. A patient who develops a new infection during treatment should undergo prompt and complete diagnostic testing, have appropriate antimicrobial therapy initiated and be closely monitored. Interrupt SOTYKTU if a patient develops a serious infection. Do not resume SOTYKTU until the infection resolves or is adequately treated.

Viral Reactivation

Herpes virus reactivation (e.g., herpes zoster, herpes simplex) was reported in clinical trials with SOTYKTU. Through Week 16, herpes simplex infections were reported in 17 patients (6.8 per 100 patient-years) treated with SOTYKTU, and 1 patient (0.8 per 100 patient-years) treated with placebo. Multidermatomal herpes zoster was reported in an immunocompetent patient. During PSO-1, PSO-2, and the open-label extension trial, the majority of patients who reported events of herpes zoster while receiving SOTYKTU were under 50 years of age. The impact of SOTYKTU on chronic viral hepatitis reactivation is unknown. Consider viral hepatitis screening and monitoring for reactivation in accordance with clinical guidelines before starting and during therapy with SOTYKTU. If signs of reactivation occur, consult a hepatitis specialist. SOTYKTU is not recommended for use in patients with active hepatitis B or hepatitis C.

Tuberculosis (TB): In clinical trials, of 4 patients with latent TB who were treated with SOTYKTU and received appropriate TB prophylaxis, no patients developed active TB (during the mean follow-up of 34 weeks). One patient, who did not have latent TB, developed active TB after receiving 54 weeks of SOTYKTU. Evaluate patients for latent and active TB infection prior to initiating treatment with SOTYKTU. Do not administer SOTYKTU to patients with active TB. Initiate treatment of latent TB prior to administering SOTYKTU. Consider anti-TB therapy prior to initiation of SOTYKTU in patients with a past history of latent or active TB in whom an adequate course of treatment cannot be confirmed. Monitor patients for signs and symptoms of active TB during treatment.

Malignancy including Lymphomas: Malignancies, including lymphomas, were observed in clinical trials with SOTYKTU. Consider the benefits and risks for the individual patient prior to initiating or continuing therapy with SOTYKTU, particularly in patients with a known malignancy (other than a successfully treated non-melanoma skin cancer) and patients who develop a malignancy when on treatment with SOTYKTU.

Rhabdomyolysis and Elevated CPK: Treatment with SOTYKTU was associated with an increased incidence of asymptomatic creatine phosphokinase (CPK) elevation and rhabdomyolysis compared to placebo.

Discontinue SOTYKTU if markedly elevated CPK levels occur or myopathy is diagnosed or suspected. Instruct patients to promptly report unexplained muscle pain, tenderness or weakness, particularly if accompanied by malaise or fever.

Laboratory Abnormalities: Treatment with SOTYKTU was associated with increases in triglyceride levels. Periodically evaluate serum triglycerides according to clinical guidelines during treatment. SOTYKTU treatment was associated with an increase in the incidence of liver enzyme elevation compared to placebo. Evaluate liver enzymes at baseline and thereafter in patients with known or suspected liver disease according to routine management. If treatment-related increases in liver enzymes occur and drug-induced liver injury is suspected, interrupt SOTYKTU until a diagnosis of liver injury is excluded.

Immunizations: Prior to initiating therapy with SOTYKTU, consider completion of all age-appropriate immunizations according to current immunization guidelines including prophylactic herpes zoster vaccination. Avoid use of live vaccines in patients treated with SOTYKTU. The response to live or non-live vaccines has not been evaluated.

Potential Risks Related to JAK Inhibition: It is not known whether tyrosine kinase 2 (TYK2) inhibition may be associated with the observed or potential adverse reactions of Janus Kinase (JAK) inhibition. In a large, randomized, postmarketing safety trial of a JAK inhibitor in rheumatoid arthritis (RA), patients 50 years of age and older with at least one cardiovascular risk factor, higher rates of all-cause mortality, including sudden cardiovascular death, major adverse cardiovascular events, overall thrombosis, deep venous thrombosis, pulmonary embolism, and malignancies (excluding non-melanoma skin cancer) were observed in patients treated with the JAK inhibitor compared to those treated with TNF blockers. SOTYKTU is not approved for use in RA.

ADVERSE REACTIONS

Most common adverse reactions (=1% of patients on SOTYKTU and more frequently than with placebo) include upper respiratory infections, blood creatine phosphokinase increased, herpes simplex, mouth ulcers, folliculitis and acne.

SPECIFIC POPULATIONS

Pregnancy: Available data from case reports on SOTYKTU use during pregnancy are insufficient to evaluate a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Report pregnancies to the Bristol-Myers Squibb Company's Adverse Event reporting line at 1-800-721-5072.

Lactation: There are no data on the presence of SOTYKTU in human milk, the effects on the breastfed infant, or the effects on milk production. SOTYKTU is present in rat milk. When a drug is present in animal milk, it is likely that the drug will be present in human milk. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for SOTYKTU and any potential adverse effects on the breastfed infant from SOTYKTU or from the underlying maternal condition.

Hepatic Impairment: SOTYKTU is not recommended for use in patients with severe hepatic impairment.

SOTYKTU is available in 6 mg tablets.
