About this study

Official title: A Phase I, First-in-human, Dose Finding Study of High Dose Rate Radiotherapy in Patients With Skin Metastases From Melanoma

This is a single center phase I, first-in-human, dose escalation study of FLASH therapy in patients with metastases of melanoma.

The trial is based on escalating single doses of FLASH therapy administered to skin melanoma metastases using the Mobetron® with high dose rate (HDR) functionality.

The aim of the study is to evaluate a dose escalation of high dose rate radiotherapy (FLASH therapy) as single dose treatment for skin melanoma metastases that progress locally despite systemic treatments. Melanoma is a typically radio-resistant tumor type, which can justify such a dose escalation with a new type of radiotherapy that appears much better tolerated than conventional radiotherapy.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • FLASH therapyDevice

    Also called high dose rate radiotherapy

    Dose escalation of high dose rate radiotherapy (FLASH therapy) as single dose treatment for skin melanoma metastases that progress locally despite systemic treatments.

Study groups in NCT04986696
Study groupRoleWhat they receive
Dose escalation of FLASH therapy in skin metastases of small volume (≤ 30 cc)Experimental7 dose levels (22 Gy; 24 Gy; 26 Gy; 28 Gy, 30 Gy, 32 Gy and 34 Gy)
Receives: Device: FLASH therapy
Dose escalation of FLASH therapy in skin metastases of large volume (> 30 and ≤ 100 cc)Experimental7 dose levels (22 Gy; 24 Gy; 26 Gy; 28 Gy, 30 Gy, 32 Gy and 34 Gy)
Receives: Device: FLASH therapy

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Determination of maximum tolerated dose (MTD) or recommended phase II dose (RP2D), separately for skin metastases of small and large volumes.

    Acute safety (dose limiting toxicity, DLT) of the high dose rate radiotherapy (RT) procedure (for each dose level) will be evaluated during the 4 weeks post-treatment using National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE v5.0).

    Measured: from Day 1 to Day 28

Secondary outcomes (8)
  1. Percentage of patients with Hemorrhage related to the treated lesions, assessed visually by the investigator

    Hemorrhage will be visually assessed (presence/abscence)

    Measured: At each visit, from screening to 12 months post-treatment

  2. Percentage of patients with Skin ulceration related to the treated lesions, assessed visually by the investigator

    Skin ulceration will be visually assessed (presence/abscence)

    Measured: At each visit, from screening to 12 months post-treatment

  3. Percentage of patients with Pain related to the treated lesions, assessed with analogic visual pain scale

    Pain will be assessed using an analogic visual pain scale (score from 1 to 10)

    Measured: At each visit, from screening to 12 months post-treatment

  4. Local response of metastases "in the radiation field", measured with calipers

    Irradiated lesions will be measured with calipers. Local response of metastases in the radiation field will be calculated as rate over all treated lesions and will be compared between small versus large volume lesions within each dose level.

    Measured: At screening, Day 1, at weeks 1, 3, 4, and 6 post-treatment; at months 3, 6, and 12 post-treatment; and at local progression

  5. Frequency of Late side effects observed "in radiation field"

    Measured: ≥ 6 months post-treatment

  6. Blinded Imaging Central Review (BICR) of photographs evaluating both tumor response and "in radiation field" normal tissue responses around the treated tumors

    A baseline photograph will be taken the day of the treatment in a pre-therapeutic setting with skin delineation of the lesion. Then photos will be repeated at 1 (+/-2d), 3 (+/-2d), 4 (+/-3d), 6 (+/-3d) weeks after treatment, then at 3 (+/-7d), 6 (+/-14d), 12 (+/-14d) months and at progression.

    Measured: From Day 1 up to 12 months post-treatment

  7. Optical coherence tomography (OCT) examination of the irradiated skin compared to the normal non-irradiated skin

    Epidermis thickness and roughness; plexus depth; number and size of vessels; number and size of hairs, will be compared between irradiated skin and normal non-irradiated skin

    Measured: at 4 weeks, 6 months and 12 months post-treatment

  8. Frequency of late adverse events (within 12 months post-treatment) for each dose

    Long-term safety of RT procedure will be measured as recording of late adverse events (CTCAE v5.0)

    Measured: within 12 months post-treatment

What does the primary outcome measure?

Determination of maximum tolerated dose (MTD) or recommended phase II dose (RP2D), separately for skin metastases of small and large volumes. (time frame: from Day 1 to Day 28). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04986696, which also lists 1 linked publication.
