Clinical Trial Summary

Multicenter, open-label, single-arm, phase II, pilot study. The screening period was up to 4 weeks and treatment took place over 20 weeks per patient. Five visits per patient were performed including: Visit 1 at week -4 to -1 (screening), Visit 2 at week 0 (baseline), Visit 3 at week 4, Visit 4 at week 12, and Visit 5 at week 20 (end of study). There was no follow-up period.


Description:

This was a multicenter, open-label, single-arm, phase II, pilot study to evaluate the efficacy and safety of apremilast involving 21 patients with PPP. The screening period was up to 4 weeks and treatment took place over 20 weeks per patient. No follow up period took place. No extension was done. Recruitment period was 4 months; hence study duration from first patient in to last patient out was approximately 9 months. About 4-6 patients per center were recruited, assuming enrolment of both genders with distribution according to prevalence of condition. Patient recruitment took place at 5 centers in Germany. The investigators had relevant expertise in diagnosing and treating PPP or were specialized in dermatology. Patients were enrolled until approximately 20 patients were included into the study. One drop-out was replaced during the recruitment phase. Five visits per patient were performed including: - Visit 1 at week -4 to -1 (screening) - Visit 2 at week 0 (baseline) - Visit 3 at week 4 - Visit 4 at week 12 - Visit 5 at week 20 (end of study) After the end of study participation the investigator ensured that the patient received a suitable therapy appropriate to patient's condition.

Intervention

Drug:
Apremilast
Apremilast was taken orally twice daily (except Day 1). Patients received tablets in blister/bottles sufficient for one month. To mitigate potential gastrointestinal side effects (primarily mild-to-moderate nausea and diarrhoea), dose titration was implemented in this study in accordance with the Summary of Product Characteristics (SmPC). A titration pack included tablets of 10, 20 and 30 mg for a period of one month. During the first 5 days, the dosage was up-titrated. The initial dose on day 1 was 10 mg in the morning; this was increased to 10 mg in the morning and evening on day 2. The evening dose was further increased by 10 mg (to 20 mg) on day 3. On day 4, the morning dose was increased to 20 mg, so that 20 mg was taken twice daily, and on day 5 the evening dose was increased to 30 mg. From Day 6 onwards, patients received the 30 mg dose twice a day. Subsequent packs included only tablets of 30 mg strength.

Outcome

Type Measure Description Time frame Safety issue
Other Hand and Feet Physician Global Assessment (H&F PGA) The H&F PGA describes the severity of psoriasis on the hands and/or feet using five categories ranging from 0 (clear) to 4 (severe). At Visit 2 (Baseline), Visit 3 (Week 4) , Visit 4 (Week 12) and Visit 5 (Week 20).
Other Pustules Count Percent Change From Baseline Percentage change from baseline in Pustules count after 20 weeks of treatment with Apremilast At Visit 2 (Baseline) and Visit 5 (End of Study - Week 20)
Other Number of Participants With Pustules Count 50 and 75 Response Patients experiencing a 50% and 75% decrease in Pustules count from baseline At Visit 3 (Week 4), Visit 4 (Week 12) and Visit 5 (End of Study-Week 20).
Other Visual Analogue Scale (VAS) Discomfort/Pain VAS was used to assess discomfort/pain. The patient was asked to place a vertical stroke on a 100 mm VAS on which the left-hand boundary represented no discomfort/pain (at 0 mm), and the right-hand boundary (at 100 mm) represented discomfort/pain as severe as can be imagined. The distance from the mark to the left-hand boundary was recorded, with higher values indicating more discomfort/pain (worse conditions). At Visit 2 (Baseline), Visit 3 (Week 4), Visit 4 (Week 12) and Visit 5 (End of Study - Week 20).
Other Visual Analogue Scale (VAS) Pruritus/Itch VAS was used to assess pruritus/itch. The patient was asked to place a vertical stroke on a 100 mm VAS on which the left-hand boundary (at 0 mm) represented no pruritus/itch, and the right-hand boundary (at 100 mm) represented pruritus/itch as severe as can be imagined. The distance from the mark to the left-hand boundary was recorded, with higher values indicating more pruritus/itch (worse outcomes). At Visit 2 (Baseline), Visit 3 (Week 4), Visit 4 (Week 12) and Visit 5 (End of Study - Week 20).
Other Psoriasis Area and Severity Index (PASI) The PASI is a measure of psoriatic disease severity taking into account qualitative lesion characteristics (erythema, thickness, and scaling) and degree of skin surface area involvement on defined anatomical regions. PASI scores range from 0 to 72, with higher scores reflecting greater disease severity. Erythema, thickness, and scaling are scored on a scale of 0 (none) to 4 (very severe) on 4 anatomic regions of the body: head, trunk, upper limbs, and lower limbs. Degree of involvement on each of the 4 anatomic regions is scored on a scale of 0 (no involvement) to 6 (90% to 100% involvement). The total qualitative score (sum of erythema, thickness, and scaling scores) is multiplied by the degree of involvement for each anatomic region and then multiplied by a constant. These values for each anatomic region are summed to yield the PASI score. At Visit 2 (Baseline), Visit 3 (Week 4), Visit 4 (Week 12) and Visit 5 (End of Study - Week 20).
Other Dynamic H&F PGA The dynamic H&F PGA describes the global improvement compared with baseline. It relies on the physician's memory of the baseline severity to evaluate the level of alteration. The categories vary between 0 (cleared) and 6 (worse). At Visit 3 (Week 4), Visit 4 (Week 12) and Visit 5 (End of Study - Week 20).
Primary Palmoplantar Pustulosis Psoriasis Area and Severity Index (PPPASI) at Week 20 Compared With Baseline The PPPASI assess palms of hands and soles of feet for psoriasis involvement. The PPPASI score range from 0-72, with higher scores indicating more severe disease. PPPASI Score at baseline and Week 20.
Secondary Number of Participants With PPPASI 50 Response PPPASI 50 response defined as a 50% decrease in PPPASI from baseline. At Visit 3 (Week 4), Visit 4 (Week 12) and Visit 5 (Week 20).
Secondary Number of Participants With PPPASI 75 Response PPPASI 75 response defined as a 75% decrease in PPPASI from baseline. At Visit 3 (Week 4), Visit 4 (Week 12) and Visit 5 (Week 20).
Secondary Dermatology Life Quality Index (DLQI) The DLQI is a dermatology-specific quality of life instrument designed to assess the impact of a disease on the patient's daily life which is also validated for PPP. It is a 10-item questionnaire and can be used to assess 6 different aspects: symptoms and feelings, leisure, daily activities, work or school performance, personal relationship and treatment. The DLQI was calculated by summing the score of each question resulting in a maximum of 30 and a minimum of 0. The higher the score, the more quality of life was impaired.
Meaning of DLQI scores:
0 to 1 = No effect at all on patient's life
2 to 5 = Small effect on patient's life
6 to 10 = Moderate effect on patient's life
11 to 20 = Very large effect on patient's life
21 to 30 = Extremely large effect on patient's life
At Visit 2 (Baseline), Visit 4 (Week 12) and Visit 5 (Week 20).
