Hidradenitis Suppurativa

Keywords

hidradenitis suppurativa, anakinra

Brief summary

This is an open-label, proof-of-concept research study to assess the effectiveness of anakinra in the treatment of patients with hidradenitis suppurativa (HS). The planned intervention is to provide about 6 HS patients with anakinra 100mg daily injections to administer subcutaneously for 8 weeks. Then, the study subjects will be followed for a further 8 weeks to monitor for relapse of HS.

Interventions

DRUGanakinra

Anakinra is supplied in individual pre-filled glass syringes 100mg/0.67mL each. It will be injected subcutaneously once daily for 8 continuous weeks.

Design outcomes

Primary

MeasureTime frameDescription
Change in Modified Sartorius ScoreBaseline, 8 weeksAt each study visit, the same physician (dermatologist) examined patients and recorded the following: (i) anatomical regions involved: axilla, groin, gluteal (left ⁄right) or other region, 3 points per region; (ii) numbers and scores of lesions (nodule 1 point, fistula 6 points) for each region; (iii) longest distance between two relevant lesions (or size of single lesion) in each region: \< 5 cm, 1 point; 5-10 cm, 3 points; \> 10 cm, 9 points; and (iv) whether all lesions are separated by normal skin: yes, 0; no (= Hurley III), 9 points. Regional scores were summed to a total score, ranging from 5 to indefinite. Smaller numbers are better scores and indicate less lesion involvement. Decreases (negative changes) from baseline indicate improvement in disease severity.

The Patient Global Assessment; The patients reported overall (global) disease activity of HS. Patients were asked What is the overall activity (pain, discharge, odor, and presence of new lesions) of hidradenitis at this visit? with a scale of 0=no acitivity to 100=maximal activity.

Outcome results

Primary

Change in Modified Sartorius Score

At each study visit, the same physician (dermatologist) examined patients and recorded the following: (i) anatomical regions involved: axilla, groin, gluteal (left ⁄right) or other region, 3 points per region; (ii) numbers and scores of lesions (nodule 1 point, fistula 6 points) for each region; (iii) longest distance between two relevant lesions (or size of single lesion) in each region: \< 5 cm, 1 point; 5-10 cm, 3 points; \> 10 cm, 9 points; and (iv) whether all lesions are separated by normal skin: yes, 0; no (= Hurley III), 9 points. Regional scores were summed to a total score, ranging from 5 to indefinite. Smaller numbers are better scores and indicate less lesion involvement. Decreases (negative changes) from baseline indicate improvement in disease severity.
