Clinical Trial Summary
: Treatment of chronic, recalcitrant HS presents significant challenges and frustration to
both the patient and the provider. In chronic, recalcitrant HS, wide surgical excision is
considered the treatment of choice.13 In 2016, Join-Lambert et al investigated the use of
intravenous (IV) ertapenem in 30 patients with severe, refractory HS.14 One gram of ertapenem
daily for 6 weeks followed by consolidation antibiotics for 6 months demonstrated promising
results in severe, recalcitrant HS.14 These patients reported significant improvements in
pain, purulent drainage, and a decrease in handicap score.14 Additionally, this technique is
less invasive than surgical excision.
Description:
Hidradenitis suppurativa (HS) is a chronic, socially and cosmetically debilitating disease
characterized by recurrent abscesses, draining sinus tracts, and scarring with a predilection
for intertriginous skin folds.1 The lesions are painful and can drain malodorous fluid,
leaving patients uncomfortable and self-conscious.1 It is not surprising that HS has a high
degree of morbidity or that these patients have among the lowest quality of life scores of
all skin disease.2-5
The pathophysiology of HS is not fully understood. It is thought to be multifactorial.1 The
primary insult is believed to be follicular occlusion with hyperkeratinization and rupture of
the follicle followed by bacterial colonization and biofilm formation.1 Most cultures of HS
lesions are polymicrobial and commonly grow gram positive bacteria and anaerobes.6,7 A recent
study observed evidence of biofilms in chronic HS lesions.8 Lesions with bacterial biofilms
respond to antibiotics initially then demonstrate resistance as the bacteria develop
metabolic adaptations and produce a protective layer, the extracellular matrix.1,8 This
results in persistent, recalcitrant lesions.6 Lesions are difficult to treat and present
significant frustration to both the patient and the provider.
The efficacy of antibiotics in HS has been explored. Antibiotics are commonly first line
therapy in HS.1,9 Rifampicin, clindamycin, and tetracycline have successfully treated HS
lesions.10,11 Other effective antibiotics include: carbapenems, fluoroquinolones, and
penicillins with β-lactamase inhibitors.9 Triple therapy with oral rifampin, moxifloxacin,
and metronidazole has been proposed.12 Although frequently successful in early stage disease,
this regimen is less effective in Hurley stage II and III HS.12 Patients with Hurley stage II
and III HS rarely experience remission on antibiotics alone. In chronic, recalcitrant HS,
wide surgical excision is considered the treatment of choice.13 The Hurley Staging system is
commonly utilized to classify the severity of a patient's hidradenitis suppurativa. Stage 1
disease consists of one or more abscesses with no sinus tract formation or scarring. Stage 2
disease involves one or more widely separated recurrent abscesses, with formation of a sinus
tract and/or scarring. Stage 3 involves multiple interconnected sinus tracts and/or abscesses
throughout an anatomical area.
In 2016, Join-Lambert et al investigated the use of intravenous (IV) ertapenem in 30 patients
with severe, refractory HS.14 One gram of ertapenem daily for 6 weeks followed by
consolidation antibiotics for 6 months demonstrated promising results in severe, recalcitrant
HS.14 These patients reported significant improvements in pain, purulent drainage, and a
decrease in handicap score.14 In this study, we propose the use of ertapenem for management
of Hurley stage 2 and 3 hidradenitis suppurativa as a less invasive means of treating HS. The
primary endpoint will be to determine the role of ertapenem in achieving Hidradenitis
Suppurativa clinical response (HiSCR) at 6 weeks. HiSCR is defined as HS Clinical Response
with ≥ 50% reduction from baseline in AN (total abscess and inflammatory nodule) count with
no increase in abscess or in draining fistula counts. Secondary endpoints include a change in
DLQI score from baseline to the end of week, work productivity and activity impairment (WPAI)
outcome from baseline to the end of week six, C- reactive protein and hemoglobin from
baseline to the end of 6 weeks, the change in HS-LASI from baseline to the end of week 6, and
ultrasound changes from baseline to the end of week 6.
Study Synopsis
1. PURPOSE: To determine the clinical efficacy of ertapenem for the treatment of Hurley stage
2 and 3 hidradenitis suppurativa (HS). We will be assessing safety and tolerability of this
medication. We will be evaluating the effect this medication has on patient's quality of
life.
2. SPECIFIC AIMS:
1. To determine the role of ertapenem in achieving Hidradenitis Suppurativa clinical
response (HiSCR) at 6 weeks. HiSCR is defined as HS clinical response of ≥ 50% reduction
from baseline in AN (total abscess and inflammatory nodule) count with no increase in
abscess or in draining fistula counts.
2. To determine the change in DLQI score from baseline to the end of week 6.
3. To determine work impairment using the questionnaire work productivity and activity
impairment- specific health problem (WPAI-SHP)
4. To determine the mean change in C- reactive protein and hemoglobin from baseline to the
end of week 6.
5. To determine the change in modified HS-LASI from baseline to the end of week 6.
6. To determine ultrasound changes from baseline to the end of week 6.
3. RATIONALE FOR THE PROJECT: Treatment of chronic, recalcitrant HS presents significant
challenges and frustration to both the patient and the provider. In chronic, recalcitrant HS,
wide surgical excision is considered the treatment of choice.13 In 2016, Join-Lambert et al
investigated the use of intravenous (IV) ertapenem in 30 patients with severe, refractory
HS.14 One gram of ertapenem daily for 6 weeks followed by consolidation antibiotics for 6
months demonstrated promising results in severe, recalcitrant HS.14 These patients reported
significant improvements in pain, purulent drainage, and a decrease in handicap score.14
Additionally, this technique is less invasive than surgical excision.
4. SIGNIFICANCE: This study will provide insight into the utility of ertapenem which can
serve as a therapeutic, less invasive option to treat patients with refractory, Hurley stage
2 and 3 hidradenitis suppurativa.
