Uno studio per verificare se il delgocitinib può aiutare a ridurre i sintomi nelle persone con lichen sclerosus (DELTA CARE 1)
Uno studio di fase 3, in doppio cieco, controllato con veicolo, per valutare l'efficacia e la sicurezza della crema di delgocitinib due volte al giorno in partecipanti adulti con lichen scleroatrofico durante un periodo di trattamento iniziale di 12 settimane seguito da un periodo di trattamento di continuazione di 40 settimane
The main objective of the study is to evaluate the efficacy of twice daily applications of delgocitinib cream compared with cream vehicle in the treatment of adult participants with mild to severe lichen sclerosus (LS). The researchers are focusing on female participants because LS is more likely to affect females compared to males.
The trial is conducted in 2 parts. Part 1 of the trial enrolls female participants with LS and results in the selection of the optimal dose for Part 2. The selected dose will then be evaluated in Part 2, which will enroll both female and male participants. Assessment of efficacy and safety of delgocitinib cream in male participants with LS will be evaluated in a substudy.
For each participant, the trial will last at least 55 weeks and up to 60 weeks.

Descrizione
Inclusion Criteria
-
Signed and dated informed consent has been obtained prior to any protocol-related procedures.
-
Age ≥18 years at the time of signing informed consent.
-
Participant is able to comply with clinic visits and trial requirements and procedures, as assessed by the investigator.
-
Female participants or male participants (assigned sex at birth and has not had any gender affirming medical procedures to their genital area) with LS in the anogenital area, regardless of treatment history. The diagnosis must be based on typical clinical features and supported by biopsy. A biopsy must be taken if there is no previous documented biopsy to support the diagnosis.
Note: Participants who also have LS-affected areas outside the anogenital area are allowed to be enrolled but these areas will not be treated with investigational medicinal product (IMP). Participants with newly diagnosed LS can be included, as well as participants who have progressive LS (including existing architectural changes).
-
Disease severity graded as mild to severe at screening and baseline according to IGA-LS score (ie, an IGA-LS score of ≥2).
-
Female participants: A woman of childbearing potential (WOCBP) must agree to use a highly effective or acceptable form of birth control throughout the trial up until the last application of IMP. Male participants: Contraceptive requirements are not applicable for male participants.
Exclusion Criteria
-
Participants with atypical presentation of LS in the anogenital area where the diagnosis is uncertain, or the suspicion of malignancy exists.
-
Female participants: History of vulvar squamous cell carcinoma (SCC), including precursor lesions (eg, human papillomavirus-independent [HPV-I] vulvar intraepithelial neoplasia [VIN] and high-grade squamous intraepithelial lesion). Male participants: History of penile SCC, including precursor lesions.
-
Female participants only: Participants with any abnormal cytology result at screening following a positive high-risk human papillomavirus (hrHPV) screening test.
-
Active dermatologic or gynecologic conditions that could confound the diagnosis of LS or interfere with assessment of the IMP (eg, urinary incontinence-associated dermatitis, genital lichen planus, and genital psoriasis), as assessed by the investigator.
-
Participants with severe urinary incontinence. Incontinence is considered severe if it occurs on most days and more than a few drops at a time.
-
Female participants: Suspected clinically (or confirmed diagnostically) of having active infection in the anogenital area, including candidiasis, Chlamydia trachomatis, Trichomonas vaginalis, Neisseria gonorrhoeae, Mycoplasma genitalium, bacterial vaginosis, or herpes simplex. Participants who test positive for sexually transmitted disease (STD)/bacterial vaginosis (BV)/anogenital candidiasis during screening can be treated, and if repeat testing is negative, these participants can be enrolled. If treatment is needed, the screening period can be extended to 6 weeks to accommodate the treatment and washout requirements.
Male participants: Suspected clinically (or confirmed diagnostically) of having active infection in the anogenital area, including candidiasis, Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, or herpes simplex. Participants who test positive for STD/anogenital candidiasis during screening can be treated, and if repeat testing is negative, these participants can be enrolled. If treatment is needed, the screening period can be extended to 6 weeks to accommodate the treatment and washout requirements.
-
Clinically significant infection within 4 weeks prior to baseline which, in the opinion of the investigator, may compromise the safety of the participant in the trial, interfere with evaluation of the IMP, or reduce the participant's ability to participate in the trial.
Clinically significant infections are defined as:
- A systemic infection.
- A serious skin infection requiring parenteral (intravenous or intramuscular) antibiotics, antiviral, or antifungal medication.
-
History of any known primary immunodeficiency disorder including a positive human immunodeficiency virus test at screening, or the participant taking antiretroviral medications as determined by medical history and/or participant's verbal report.
-
Major surgery within 8 weeks prior to screening or planned in-patient surgery or hospitalization during the trial period.
-
History of cancer:
• Female participants: Participants who have had basal cell carcinoma or localized SCC of the skin (outside the anogenital area), or in situ carcinoma of the cervix are eligible provided that curative therapy was successfully completed at least 12 months prior to screening.
Participants who have had other malignancies (except vulvar SCC) are eligible provided that the participant is in remission and curative therapy was completed at least 5 years prior to screening.
• Male participants: Participants who have had basal cell carcinoma or localized SCC of the skin (outside the anogenital area) are eligible provided that curative therapy was successfully completed at least 12 months prior to screening.
Participants who have had other malignancies (except penile SCC) are eligible provided that the participant is in remission and curative therapy was completed at least 5 years prior to screening.
-
Positive hepatitis B surface antigen and/or hepatitis B core antibody and positive for hepatitis B virus deoxyribonucleic acid (participants who have tested positive for hepatitis B core antibody are eligible if tests for hepatitis B surface antigen and hepatitis B virus deoxyribonucleic acid are negative), or positive hepatitis C virus antibody serology confirmed by hepatitis C virus ribonucleic acid (RNA) at screening.
-
Known or suspected hypersensitivity to any component(s) of the IMP(s).
-
Any disorder which is not stable and according to the investigator could:
- Affect the safety of the participant throughout the trial.
- Hinder the participant's ability to complete the trial.
Examples include, but are not limited to, cardiovascular, gastrointestinal, hepatic, renal, neurological, musculoskeletal, infectious, endocrine, metabolic, hematological, immunological, and psychiatric disorders, and major physical impairment.
-
Any abnormal finding which according to the investigator may:
- Put the participant at risk because of their participation in the trial.
- Influence the participant's ability to complete the trial.
The abnormal finding must be clinically significant and observed during the screening period. Examples include abnormal findings in physical examination, vital signs, electrocardiogram (ECG), hematology, or biochemistry.
-
Current or recent chronic alcohol or drug abuse, or any other condition associated with poor compliance as judged by the investigator.
-
Female participants only: Women who are pregnant or lactating. For women of childbearing potential, a negative pregnancy test is required at screening.
-
Systemic treatment with immunosuppressive drugs (eg, methotrexate, cyclosporine), immunomodulating drugs, retinoids, or corticosteroids within 4 weeks prior to baseline.
-
Cutaneously applied treatment with immunomodulators (eg, topical calcineurin inhibitor [TCI]) or topical corticosteroid (TCS) on the anogenital area within 2 weeks before baseline.
-
Use of systemic or topical Janus kinase (JAK) inhibitors (including delgocitinib) within 4 weeks before baseline.
-
Systemic or cutaneous (applied in the anogenital area) use of antibiotics, antiparasitics, antivirals, or antifungals within 1 week before baseline.
-
