5 Warnings and Precautions

5.8 Potential Risks Related to JAK Inhibition

Additions and/or revisions underlined:

It is not known whether 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.

Hypoglycemia, including severe hypoglycemia, has been reported following initiation of JAK inhibitors in patients with diabetes. Advise diabetic patients to notify their healthcare provider(s) if they develop signs or symptoms of hypoglycemia.

MEDICATION GUIDE

Additions and/or revisions underlined:

Before taking SOTYKTU, tell your healthcare provider about all of your medical conditions, including if you:

  • have diabetes

What are the possible side effects of SOTYKTU? SOTYKTU may cause serious side effects, including:

  • Potential risks from Janus kinase (JAK) inhibition. SOTYKTU is a tyrosine kinase 2 (TYK2) inhibitor. TYK2 is in the JAK family. It is not known whether taking SOTYKTU has the same risks as taking JAK inhibitors. Increased risk of death (all causes) has happened in people who were 50 years of age and older with at least 1 heart disease (cardiovascular) risk factor who were taking a JAK inhibitor used to treat rheumatoid arthritis (RA) compared to people taking another medicine in a class of medicines called TNF blockers. SOTYKTU is not for use in people with RA. Low blood sugar (hypoglycemia) in people with diabetes has happened after taking JAK inhibitors. Tell your healthcare provider if you have any problems with low blood sugar.

PATIENT COUNSELING INFORMATION

Additions and/or revisions underlined:

Potential Risks Related to JAK Inhibition

5 Warnings and Precautions

5.1 Hypersensitivity Reactions

Subsection title revised

Hypersensitivity reactions, such as angioedema, have been reported in subjects receiving SOTYKTU. If a clinically significant hypersensitivity reaction occurs, institute appropriate therapy and discontinue SOTYKTU [see Contraindications (4)].

5.2 Infections

Additions and/or revisions underlined:

. . .

Consider the risks and benefits of SOTYKTU prior to initiating treatment 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 with SOTYKTU. Patients who develops a new infection during treatment with SOTYKTU should undergo prompt and complete diagnostic testing, have appropriate antimicrobial therapy be initiated, and be closely monitored. Interrupt SOTYKTU if a serious infection occurs. 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 [see Adverse Reactions (6.1)]. In the 16-week placebo-controlled period of Trials PSO-1 and PSO-2, herpes simplex infections were reported in 17 subjects (6.8 per 100 patient-years) treated with SOTYKTU, and 1 subject (0.8 per 100 patient-years) treated with placebo. Multidermatomal herpes zoster was reported in an immunocompetent subject who received SOTYKTU.

The clinical implications of SOTYKTU on viral hepatitis reactivation are unknown. Subjects with positive screening tests for hepatitis B or C, or chronic hepatitis B, or untreated hepatitis C were excluded from clinical trials or closely monitored for evidence of reactivation. Consider viral hepatitis screening and monitoring for reactivation in accordance with clinical guidelines before starting therapy 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.

5.3 Tuberculosis

Additions and/or revisions underlined:

In Trials PSO-1 and PSO-2, of 4 subjects with latent tuberculosis (TB) who were treated with SOTYKTU and received appropriate TB prophylaxis, no subjects developed active TB (during the mean follow-up of 34 weeks). One subject, who did not have latent TB, developed active TB after receiving 54 weeks of SOTYKTU.

. . .

5.6 Laboratory Abnormalities

Additions and/or revisions underlined:

. . .

Liver Enzyme Elevations - Treatment with SOTYKTU has been associated with liver enzyme elevation. Liver serum transaminase elevations greater than or equal to 3 times the ULN have been reported in subjects treated with SOTYKTU [see Adverse Reactions (6.1)]. Evaluate liver enzymes at baseline and during treatment SOTYKTU in patients with known or suspected liver disease according to routine patient management. If increases in liver enzymes occur and drug-induced liver injury is suspected, interrupt SOTYKTU until a diagnosis of liver injury is excluded.

5.7 Immunizations

Additions and/or revisions underlined:

Prior to initiating therapy with SOTYKTU, complete 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.


6 Adverse Reactions

Additions and/or revisions underlined:

The following adverse reactions are discussed in greater detail in other sections of labeling:

. . .

  • Elevated CPK [see Warnings and Precautions (5.5)]

6.1 Clinical Trials Experience

Additions and/or revisions underlined:

. . .

Plaque Psoriasis Clinical Trials

The safety of SOTYKTU was evaluated in two placebo- and active-controlled trials (Trial PSO-1 and Trial PSO-2) and an open-label extension trial in which subjects who completed Trial PSO-1 or Trial PSO-2 could enroll [see Clinical Studies (14.1)]. In these clinical trials, a total of 1,519 subjects with moderate-to-severe plaque psoriasis who were candidates for systemic therapy or phototherapy received SOTYKTU 6 mg orally once daily. Of these, 1,141 subjects were exposed to SOTYKTU for at least one year.

In Trials PSO-1 and PSO-2, 1,681 subjects were randomized to receive SOTYKTU 6 mg once daily (840 subjects), placebo (419 subjects), or apremilast 30 mg twice daily (422 subjects). All subjects randomized to placebo switched to SOTYKTU at Week 16. All other subjects remained in their original treatment group until Week 24, at which point subjects could have continued on the same treatment or be switched to SOTYKTU or placebo. The mean age of subjects was 47 years. The majority of subjects were White (87%) and male (67%).

. . .

Specific Adverse Reactions

Exposure adjusted incidence rates are reported for all the adverse reactions presented below.

Infections

In the 16-week placebo-controlled period, infections occurred in 29% of subjects in the SOTYKTU group (116 events per 100 patient-years) compared to 22% of subjects in the placebo group (83.7 events per 100 patient-years). The majority of infections were non-serious and mild to moderate in severity and did not lead to discontinuation of SOTYKTU.

. . .

Psoriatic Arthritis Clinical Trials

The safety of SOTYKTU was evaluated in two placebo-controlled clinical trials in adults with active psoriatic arthritis, Trials PsA-1 and PsA-2 [see Clinical Studies (14.2)].

The overall safety profile of SOTYKTU observed in subjects with active psoriatic arthritis was generally consistent with the safety profile observed in subjects with plaque psoriasis.


8 Use in Specific Populations

8.1 Pregnancy

Additions and/or revisions underlined:

Risk Summary

. . .

In animal reproduction studies, no effects on embryo-fetal development were observed with oral administration of deucravacitinib to rats and rabbits during organogenesis at doses that were at least 72 times the maximum recommended human dose (MRHD) of 6 mg once daily (see Data).

. . .

Data

Animal data

Deucravacitinib was administered orally during the period of organogenesis at doses of 5, 15, or 75 mg/kg/day in rats and 1, 3, or 10 mg/kg/day in rabbits. Deucravacitinib was not associated with embryo-fetal lethality or fetal malformations in either species. These doses resulted in maternal exposures (AUC) that were 211 times (rat) or 72 times (rabbit) the exposure at the MRHD.

In a pre- and post-natal development study in rats, deucravacitinib was administered orally from gestation day 6 through lactation day 20, at doses of 5, 15, or 50 mg/kg/day. At 50 mg/kg/day, F1 offspring had reduced body weight gains during the pre-weaning period. After weaning, body weights of affected F1 offspring gradually normalized to control levels. No maternal effects were observed at 50 mg/kg/day (87 times the MRHD based on AUC comparison). No deucravacitinib-related effects on postnatal developmental, neurobehavioral, or reproductive performance of offspring were noted at doses up to 15 mg/kg/day (15 times the MRHD based on AUC comparison).

8.5 Geriatric Use

Additions and/or revisions underlined:

Plaque Psoriasis

In clinical trials of SOTYKTU in adults with moderate to severe plaque psoriasis, of the 1,519 subjects, 152 (10%) subjects were 65 years or older and 21 (1.4%) subjects were 75 years or older.

During the Week 0-16 period of the clinical trials 80 subjects greater than or equal to 65 years old, including 12 subjects greater than or equal to 75 years old, who received SOTYKTU without switching treatment arms, had a higher incidence of overall serious adverse reactions, including serious infections, and discontinuations due to adverse reactions compared with younger adult subjects.

No overall differences in effectiveness of SOTYKTU have been observed between patients 65 years of age and older and younger adult patients.

Psoriatic Arthritis

In clinical trials of SOTYKTU in adults with active psoriatric arthritis, of the 1312 subjects treated with SOTYKTU, 171 (13%) patients were 65 years or older and 22 (1.7%) subjects were 75 years or older. No overall differences safety or effectiveness of SOTYKTU or exposure of deucravacitinib were observed between subjects 65 years of age and older and younger adult subjects.
