Merkel Positron Emission Tomography (PET) Protocol (MP3)

November 17, 2022 updated by: Trans Tasman Radiation Oncology Group

A Phase II Efficacy Study of Chemo-Radiotherapy in PET Stage II and III Merkel Cell Carcinoma of the Skin

A Phase II Study designed to evaluate the efficacy of Chemo-Radiotherapy in achieving loco-regional control in patients with Merkel Cell Carcinoma (MCC) of the skin. Patients will undergo PET scans to assist in staging and planning the patient's treatment as well as assessing response at the conclusion of treatment.

Intervention / Treatment

Intervention / Treatment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Arm A
Conventional radical radiotherapy in this trial means that those patients with microscopic disease receive a dose of 50Gy using daily incremental fractions of 2Gy over 25 fractions and those with macroscopic disease receive 54Gy in 27 fractions.
Drug: Carboplatin

During radiotherapy: Carboplatin (AUC2) commences on day 1 of radiation and is repeated at weekly intervals on days 8, 15, 22 and 29 (of radiation).

After radiotherapy: 3 weeks after completing radiotherapy, 3 cycles of 3 weekly carboplatin (AUC4.5) intravenously on day 1.

Drug: Etoposide
After Radiotherapy: 3 weeks after completing the radiation therapy, 3 cycles of 3 weekly etoposide (80mg/M2/day) intravenously days 1-3
Radiation: Radiotherapy

Microscopic Disease: 50Gy delivered in 2Gy doses over 25 fractions

Macroscopic Disease: 54Gy delivered in 2Gy doses over 27 fractions

  • RT
  • Radiation Therapy

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
