      <textblock>
        The study is a randomized, proof of concept study. 30 patients aged 18 and over with HS will&#xD;
        be included in this single center, randomized, double-blind, parallel-group study. Dosage of&#xD;
        deucravacitinib will be given according to the investigational regimen as follows: 6 mg po&#xD;
        bid for 16 weeks. The study compromises a 4-week screening period, a 16-week study period,&#xD;
        and a 4-week follow-up period. The follow-up period consists of a follow-up phone call 4&#xD;
        weeks after the last study drug dose.&#xD;

    <detailed_description>
      <textblock>
        The objective of this study is to investigate the efficacy of Deucravacitinib (BMS- 986165)&#xD;
        in the treatment of Hidradenitis Suppurativa.&#xD;
  &#xD;
        Subjects will be randomly assigned to receive either Deucravacitinib (6 mg twice daily) or&#xD;
        placebo for 16 weeks. Assessments will be performed at Baseline and weeks 4, 8, 12, and 16 by&#xD;
        a blinded investigator. During this visits, subjects will also be asked to complete a quality&#xD;
        of life questionnaire (DLQI) and Visual Analog Scale (VAS) for pain.&#xD;
  &#xD;
        A total enrollment of 30 subjects (20 study drug, 10 placebo) is anticipated in this single-&#xD;
        center, randomized, double-blind, parallel-group study. This study powered to show a&#xD;
        significant difference in efficacy of treatment using the following assumptions based on&#xD;
        other clinical trials: baseline average inflammatory lesion count of 12, improvement of 7 in&#xD;
        the treatment group and 3 in the placebo group, with a power of 0.87, SD of 3.25 and alpha&#xD;
        level of 0.05. The HiSCR will be a secondary endpoint (reduction of inflammatory lesions by&#xD;
        50% with no increase in fistulas or abscesses).&#xD;

      <time_frame>Baseline and Week 16</time_frame>
      <description>The number and proportion of participants who achieve a HiSCR at Weeks 16 will be summarized and compared to placebo. HiSCR is a validated, binary outcome and is defined as at least a 50% reduction from baseline in the total abscess and inflammatory- nodule count, with no increase in the abscess or draining fistula count.&#xD;
  HiSCR Assessment Relative to baseline, all three criteria must be met.&#xD;
  &gt;50% reduction in the total number of inflammatory nodules and abscesses&#xD;
  No increase in abscess count&#xD;
  No increase in draining fistula count</description>

      <time_frame>Baseline, weeks 4, 8, 12, and 16</time_frame>
      <description>The novel IHS4 is a validated tool to dynamically assess HS severity and can be used both in real-life and the clinical trials setting.&#xD;
  The resulting IHS4 score is arrived at by the number of nodules (multiplied by 1) plus the number of abscesses (multiplied by 2) plus the number of draining tunnels (multiplied by 4). A total score of 3 or less signifies mild, 4-10 signifies moderate and 11 or higher signifies severe disease.</description>

      <measure>Changes in Hurley Stage scores at weeks 4, 8, 12, and 16 compared to baseline.</measure>
      <time_frame>Baseline, weeks 4, 8, 12, and 16</time_frame>
      <description>Hurley Staging is a surgical staging system used to describe disease severity. No improvement in Hurley scoring is expected with medical management alone. Pre- and post-study drug scores will be compared.&#xD;
  The Hurley clinical staging system is used to classify patients with HS into three disease severity groups.&#xD;
  Stage I - abscess formation (single or multiple), no sinus tracts or cicatrization/scarring.&#xD;
  Stage II - recurrent abscesses with sinus tracts and scarring, single or multiple separated lesions.&#xD;
  Stage III - diffuse or almost diffuse involvement, or multiple interconnected sinus tracts and abscesses across the entire area</description>

      <time_frame>Baseline, weeks 4, 8, 12, and 16</time_frame>
      <description>A Quality of Life Score will be calculated based upon the Dermatology Life Quality Index (DLQI).&#xD;
  The DLQI is a validated general dermatology questionnaire that consists of 10 items that assess subject health-related quality of life (daily activities, personal relationships, symptoms and feelings, leisure, work and school, and treatment). It has been extensively used in dermatology clinical trials for AD. The DLQI is a psychometrically valid and reliable instrument that has been translated into several languages, and the DLQI total scores have been shown to be responsive to change.&#xD;
  The minimally important difference for the DLQI has been estimated as a 2 to 5 point change from baseline.</description>

      <time_frame>Baseline, weeks 4, 8, 12, and 16</time_frame>
      <description>A Pain Score will be calculated based upon a 10-point visual analog pain scale, which has been widely used to rate pain in both children and adults and has also been used in dermatology clinical trials.&#xD;
  Response based on an improvement from baseline at all scheduled time points will be calculated. We will compare pre and post treatment pain values and categorize patients as (i) Resolved (ii) Improved (iii) Stable (iv) Worsened</description>

      <time_frame>Baseline and weeks 4, 8, 12 and 16</time_frame>
      <description>Secondary exploratory endpoints include change in ulceration and change in overall disease severity by clinical phenotype. No current scoring system exists in HS for ulcerations. Subjects with ulceration present at baseline visit will be assessed for change in ulceration number by anatomical region or size (&gt;25% decrease, &gt;50% decrease, 75% decrease, &gt;90% decrease).</description>

        weeks after the last study drug dose.
  The objective of this study is to investigate the efficacy of Deucravacitinib (BMS- 986165)
        in the treatment of Hidradenitis Suppurativa.
  
        Subjects will be randomly assigned to receive either Deucravacitinib (6 mg twice daily) or
        placebo for 16 weeks. Assessments will be performed at Baseline and weeks 4, 8, 12, and 16 by
        a blinded investigator. During this visits, subjects will also be asked to complete a quality
        of life questionnaire (DLQI) and Visual Analog Scale (VAS) for pain.
  
        A total enrollment of 30 subjects (20 study drug, 10 placebo) is anticipated in this single-
        center, randomized, double-blind, parallel-group study. This study powered to show a
        significant difference in efficacy of treatment using the following assumptions based on
        other clinical trials: baseline average inflammatory lesion count of 12, improvement of 7 in
        the treatment group and 3 in the placebo group, with a power of 0.87, SD of 3.25 and alpha
        level of 0.05. The HiSCR will be a secondary endpoint (reduction of inflammatory lesions by
        50% with no increase in fistulas or abscesses).
  allocation: Randomized
  intervention model: Parallel Assignment
  primary purpose: Treatment
  masking: Double (Participant, Investigator)
  measure: Change from Baseline in Inflammatory lesion counts (including combined counts of inflammatory nodules (N) and abscesses (A)/AN count) at week 16.
  time frame: Baseline and Week 16
  description: We will assess the average change in inflammatory lesion count per subject following 16 weeks of treatment as compared to baseline. Inflammatory lesions are defined as inflammatory nodules or abscesses.
  measure: The population treatment effect on proportion of participants with Hidradenitis Suppurativa Clinical Response (HiSCR) at week 16 for the active treatment group relative to placebo without regard to IP compliance
  time frame: Baseline and Week 16
  description: The number and proportion of participants who achieve a HiSCR at Weeks 16 will be summarized and compared to placebo. HiSCR is a validated, binary outcome and is defined as at least a 50% reduction from baseline in the total abscess and inflammatory- nodule count, with no increase in the abscess or draining fistula count.
  HiSCR Assessment Relative to baseline, all three criteria must be met.
  >50% reduction in the total number of inflammatory nodules and abscesses
  No increase in abscess count
  No increase in draining fistula count
  measure: Changes in IHS4 scores at weeks 4, 8, 12, and 16 compared to baseline.
  time frame: Baseline, weeks 4, 8, 12, and 16
  description: The novel IHS4 is a validated tool to dynamically assess HS severity and can be used both in real-life and the clinical trials setting.
  The resulting IHS4 score is arrived at by the number of nodules (multiplied by 1) plus the number of abscesses (multiplied by 2) plus the number of draining tunnels (multiplied by 4). A total score of 3 or less signifies mild, 4-10 signifies moderate and 11 or higher signifies severe disease.
  measure: Changes in Hurley Stage scores at weeks 4, 8, 12, and 16 compared to baseline.
  time frame: Baseline, weeks 4, 8, 12, and 16
  description: Hurley Staging is a surgical staging system used to describe disease severity. No improvement in Hurley scoring is expected with medical management alone. Pre- and post-study drug scores will be compared.
  The Hurley clinical staging system is used to classify patients with HS into three disease severity groups.
  Stage I - abscess formation (single or multiple), no sinus tracts or cicatrization/scarring.
  Stage II - recurrent abscesses with sinus tracts and scarring, single or multiple separated lesions.
  Stage III - diffuse or almost diffuse involvement, or multiple interconnected sinus tracts and abscesses across the entire area
  measure: Changes in Dermatology Life Quality Index (DLQI) scores at weeks 4, 8, 12, and 16 compared to baseline.
  time frame: Baseline, weeks 4, 8, 12, and 16
  description: A Quality of Life Score will be calculated based upon the Dermatology Life Quality Index (DLQI).
  The DLQI is a validated general dermatology questionnaire that consists of 10 items that assess subject health-related quality of life (daily activities, personal relationships, symptoms and feelings, leisure, work and school, and treatment). It has been extensively used in dermatology clinical trials for AD. The DLQI is a psychometrically valid and reliable instrument that has been translated into several languages, and the DLQI total scores have been shown to be responsive to change.
  The minimally important difference for the DLQI has been estimated as a 2 to 5 point change from baseline.
  measure: Changes in Visual Analogue Scale (VAS) pain scores at weeks 4, 8, 12, and 16 compared to baseline.
  time frame: Baseline, weeks 4, 8, 12, and 16
  description: A Pain Score will be calculated based upon a 10-point visual analog pain scale, which has been widely used to rate pain in both children and adults and has also been used in dermatology clinical trials.
  Response based on an improvement from baseline at all scheduled time points will be calculated. We will compare pre and post treatment pain values and categorize patients as (i) Resolved (ii) Improved (iii) Stable (iv) Worsened
  measure: Change from baseline in draining fistula counts at week 16.
  time frame: Baseline and Week 16
  measure: Changes in lesion counts (A, N, AN) at weeks 4, 8, and 12 compared to baseline.
  time frame: Baseline and weeks 4, 8, and 12
  description: We will assess the average change in inflammatory lesion count per subject following 4, 8, 12, and 16 weeks of treatment as compared to baseline. Inflammatory lesions are defined as inflammatory nodules or abscesses.
  measure: Changes in ulceration at weeks 4, 8, 12, and 16 compared to baseline.
  time frame: Baseline and weeks 4, 8, 12 and 16
  description: Secondary exploratory endpoints include change in ulceration and change in overall disease severity by clinical phenotype. No current scoring system exists in HS for ulcerations. Subjects with ulceration present at baseline visit will be assessed for change in ulceration number by anatomical region or size (>25% decrease, >50% decrease, 75% decrease, >90% decrease).
  measure: Change in clinical phenotype at week 16 compared to baseline.
  time frame: Baseline and week 16
  description: Clinical phenotype of subject (Follicular nodular phenotype vs. infiltrating phenotype vs. comedonal phenotype vs. ulcerating phenotype) will be identified at baseline. Subjects will be reassessed every 4 weeks to identify any shifts in phenotype with therapy. At week 16, descriptive sub- analysis will be performed to identify any clinical phenotypes that are more or less likely to respond to TYK2 inhibition.
