Main objective

Scope: Safety, Dose response, Therapy, Efficacy

Determine the effectiveness of MTX in prevention of recurrence in dVIN by the time-to recurrence before and after the use of MTX in women with therapy resistant lichen sclerosus and recurrent dVIN lesions.

Secondary objectives 5

  1. Safety and tolerability of side effects with MTX use and foliac acid.
  2. Reduction of vulvar complaints since MTX use.
  3. Reduction of topical corticosteroid application since MTX introduction.
  4. Patient satisfaction with the use of MTX.
  5. Tumor microenvironment in recurrent dVIN lesions.

Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 3

  1. Age of 18 years or older.
  2. Failure to standard therapy with intensive clobetasol ointment either or not combined with tacrolimus 0,1% ointment. Failure to standard therapy is defined by complaints of lichen sclerosus which are insufficiently controlled by the topical therapy.
  3. Recurrent dVIN lesions, at least 1 previous dVIN, for which surgical treatment has been performed.

Exclusion criteria 13

  1. Concomitant diagnoses of vulvar cancer
  2. Severe decreased liver function with a serum bilirubin value >85,5umol/l or >5mg/dl
  3. Severe decreased kidney function with creatinine clearance of <30ml/min
  4. Bone marrow diseases (including leukopenia, thrombocytopenia, anemia, bone marrow hypoplasia)
  5. Acute or chronic infections (including HIV/AIDS, tuberculosis)
  6. Immunodeficiency or immunosuppressive medication
  7. Severe pulmonary disease
  8. Pregnancy or current pregnancy wish
  9. Legal incapability
  10. Insufficient knowledge of the Dutch or English language

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 2

  1. To assess effectiveness of MTX in prevention of recurrence in dVIN, recurrence rates with or without MTX will be compared within this prospective self-controlled pilot study, as each patient functions as its own control.
  2. Time-to recurrence of dVIN in women with lichen sclerosus and recurrent dVIN lesions with- and without the use of MTX will also be assessed by determination of clinical responses at 1-3-6-9-12-15-18 months and will be identified as stable disease (SD) or progressive disease (PD).

Secondary endpoints 2

  1. Safety and tolerability of side effects, reduction of vulvar complaints, reduction of topical corticosteroid application and patient satisfaction with the use of MTX will be evaluated by patient reported use and documentation of side effects using a questionnaire. Severity of side effects will be evaluated according to the CTCEA version 5.0 2017.
  2. Pre-treatment and, when performed, current- or post-treatment biopsies will be identified and central blinded pathology revision will be performed. To explore microenvironment in recurrent dVIN with and without the use of MTX immunohistochemistry staining, including p53 will be performed.
