Strongly recommended by AAD as a systemic therapy for moderate-to-severe atopic dermatitis in adult patients1
Kalvin, a real Adbry patient. Individual results may vary.
The efficacy and safety of Adbry were assessed in 3 randomized, double-blind, placebo-controlled trials8
q2w=every 2 weeks; q4w=every 4 weeks; TCS=topical corticosteroid.
Adbry was administered via subcutaneous injection.
*Responders defined as achieving the primary endpoints of IGA 0 or 1 or EASI-75 at Week 16.
Nonresponders at Week 16 and subjects who lost clinical response during the maintenance period were placed on open-label treatment with Adbry 300 mg every other week and optional use of TCS.
†Placebo responders continued on placebo to maintain blind participation and were not included in analyses after Week 16.
Adbry was administered via subcutaneous injection.
*Responders defined as achieving the primary endpoints of IGA 0 or 1 or EASI-75 at Week 16. Subjects who did not achieve clinical response at Week 16 received Adbry 300 mg every other week + TCS for another 16 weeks.
†A midpotency TCS (ie, mometasone furoate 0.1% cream) was dispensed at each dosing visit. The subjects were instructed to apply a thin film of the dispensed TCS as needed, once daily, to active lesions from Week 0 to Week 32, and were to discontinue treatment with TCS when control was achieved. An additional, lower-potency TCS or TCI could be used at the investigator’s discretion on areas of the body where use of the supplied TCS was not advisable, such as areas of thin skin.
‡Placebo responders continued on placebo to maintain blind participation and were not included in analyses after Week 16.
Example of improvement in EASI from baseline to Week 16 in a patient receiving Adbry in the INJECZTRA study.12 Individual patient results may vary.
In ECZTRA 1 and 2, a percentage of responders at Week 16 who were re-randomized to placebo maintained their response at Week 52 without any TCS use in a pooled analysis10*†
In some patients who achieved response at Week 16, a remittive effect was seen at Week 52 after Adbry withdrawal.
Q2W=every 2 weeks; Q4W=every 4 weeks; TCS=topical corticosteroid.
*Responders were defined as subjects with an IGA 0 or 1 (“clear” or “almost clear”) or EASI-75 at Week 16. At Week 16, responders were re-randomized to Adbry 300 mg Q2W, Adbry Q4W, or placebo every other week for another 36 weeks.
†Subjects who received rescue treatment or with missing data were considered nonresponders.
The ECZTEND OLE (open-label extension) study demonstrated long-term results with up to 4 years of data14
EASI=Eczema Area and Severity Index.
*Median EASI score at pivotal trial baseline: 26.7; at ECZTEND baseline: 4.7; at week 152: 1.4.10
†Variable time between last treatment in parent trial and first treatment in ECZTEND (maximum 26 weeks).
‡A total of 2666 patients from the ECZTRA 1, 2, 3, 5, 6, 7, and 8 parent trials were enrolled in ECZTEND as of data cutoff. Data presented from a post-hoc interim analysis of an ongoing OLE trial represent a selected subgroup of patients (n=347) from the parent trials ECZTRA 1 and 2 who elected to enter the ECZTEND trial and had consistently received Adbry for a total of up to 4 years at data cutoff (April 30, 2022). As such, data may not be generalizable to the full Adbry population.
Limitations:
Limitations and context associated with the open-label study design and data are described above and include decreasing sample size, potential continued involvement of responders, and attrition of nonresponders. Data presented are descriptive in nature and no statistical comparisons are made.
ECZTEND is an ongoing Phase 3, long-term, five-year, open-label, single-arm extension trial to evaluate the safety and efficacy of Adbry in patients with AD who participated in the previous Adbry parent trials. Patients were permitted to enter ECZTEND after completion of the parent trial regardless of their treatment response or whether they were treated with Adbry or placebo. Patients received a loading dose followed by 300 mg q2w plus optional TCS as needed.14
ADBRY® (tralokinumab-Idrm) injection is indicated for the treatment of moderate-to-severe atopic dermatitis in patients aged 12 years and older whose disease is not adequately controlled with topical prescription therapies or when those therapies are not advisable. ADBRY can be used with or without topical corticosteroids.
