Outcome Measures

Primary Outcomes (1)

  • Assess the feasibility of DaRT by the safety of DaRT for the treatment of Primary and Recurrent Squamous Cell Carcinoma of the Vulva

    Measuring the feasibility of using the device by the treatment-related adverse events in the follow-up period (graded 1 'not significant' to 5 'death' with Common Terminology Criteria for Adverse Events v5.0)

    6 months

Secondary Outcomes (7)

  • Assess the efficacy of DaRT for the treatment of Primary and Recurrent Squamous Cell Carcinoma of the Vulva

    Day 28 (4 weeks)

  • To evaluate the effect DaRT on the immunological response

    4-6 weeks

Study Arms (1)

DaRT Diffusing Alpha-emitters Radiation Therapy

EXPERIMENTAL

DaRT Diffusing Alpha-emitters Radiation Therapy using the DaRT applicator and seeds, inserted for 14 days prior to removal.

Radiation: DaRT Diffusing Alpha-emitters Radiation Therapy

Interventions

DaRT is a brachytherapy treatment comprising stainless-steel 316LVM wires coated with radium-224 (Alpha DaRT seeds). The radioactive seeds are inserted directly into the tumour on the perineum and will be removed after 14 days.

Gender Eligibility DetailsEligibility based on sex assigned at birth
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Newly diagnosed or recurrent (local) vulva cancer with or without distant metastases
  • Histopathological confirmation of squamous cell carcinoma
  • Macroscopic tumour in situ (i.e. tumour not excised)
  • Age 18 years and over
  • ECOG performance status 0-2
  • Life expectancy more than 6 months
  • Willing and able to give written informed consent to participate
  • Measurable target according to RECIST v1.1
  • Tumour size ≤ 7 centimetres in the longest diameter
  • Target is technically amenable for full coverage by the DaRT seeds

You may not qualify if:

  • Non-squamous histology
  • Concomitant illnesses which may increase risk of radiation toxicity e.g. autoimmune diseases, vasculitis, etc.
  • Concomitant immunosuppressive and/or long-term corticosteroid treatment
  • Involvement in other studies that may affect evaluation of response or toxicity of DaRT in the past 30 days or 5 half-lives of the investigational product, whichever is longer
  • Pregnancy or breastfeeding
  • Women of child-bearing potential unwilling to use adequate contraception for the duration of the study and 6 months after completion (further details in CIP section 13)
  • Nodal recurrence without local recurrence
  • Previous diagnosis of other malignancy \< 3 years of enrolment (excluding non-melanomatous skin cancer)
  • No concurrent chemotherapy
  • Patients who have received prior chemotherapy or targeted therapy require a 1-month washout before DaRT insertion
  • Requirement to start chemotherapy within 6 weeks of DaRT insertion
