Alpha Radiation Emitters Device for the Treatment of Primary and Recurrent Squamous Cell Carcinoma of the Vulva (DaRT).

Официальное название

A Feasibility and Safety Study of Intratumoral Diffusing Alpha Radiation Emitters for the Treatment of Primary and Recurrent Squamous Cell Carcinoma of the Vulva

Обзор

A unique approach for cancer treatment employing intratumoral diffusing alpha radiation emitter device for the treatment of Primary and Recurrent Squamous Cell Carcinoma of the Vulva.

Подробное описание

This is an prospective Open label, single arm, multi center, interventional study treatment of Primary and Recurrent Squamous Cell Carcinoma of the Vulva .The study objectives are to collect data on the Feasibility and Safety of DaRT among patients who do not fit the entry of existing investigational trials.

The primary endpoint of the study is to evaluate the feasibility and safety of the Alpha DaRT sources for the treatment of vulva SCC. Feasibility will be determined according to the rate of successful placement of Alpha DaRT . Safety will be determined according to the overall incidence of device related AEs and SAE's graded according to CTCAE v5.0 criteria.

The Secondary endpoint of the study will be to evaluate efficacy, as determined by local control evaluation according to RECIST v1.1

Вмешательства

• Устройство DaRT seeds
  An intratumoral insertion of a seed(s), loaded with Radium-224, securely fixed in the seeds. The seeds release by recoil into the tumor short-lived alpha-emitting atoms

Первичные конечные точки

• Feasibility - DaRT seed placement [Срок оценки: immediately following the insertion procedure]
• Safety - Adverse events [Срок оценки: From day 0]

Вторичные конечные точки (1)

• Efficacy -Alpha DaRT seeds [Срок оценки: 1, 3, and 6 months post DaRT insertion].]

Критерии исключения

• Patients with uncontrolled intercurrent illnesses including, but not limited to an active infection requiring systemic therapy (not including cholangitis) or a known psychiatric or substance abuse disorder(s) that would interfere with cooperation with the requirements of the trial or interfere with the study endpoints.
• Has a known additional malignancy that is progressing or requires active treatment. Exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy or in situ cervical cancer.
• Patient requires treatment not specified in this protocol which may conflict with the endpoints of this study including evaluation of response or toxicity of Alpha DaRT.
• Volunteers participating in another interventional study in the past 30 days which might conflict with the endpoints of this study or the evaluation of response or toxicity of Alpha DaRT.
• High probability of protocol non-compliance (in opinion of investigator).
• Breastfeeding women or women of childbearing potential unwilling or unable to use an acceptable contraceptive method to prevent pregnancy for 3 months after RT.
