Locally Advanced NSCLC Hyperfractionated RT (ADAPT)

May 5, 2021 updated by: Duke University

Phase II Study of Accelerated and Adaptive Radiation Therapy for Locally-Advanced Non-Small Cell Lung Cancer (NSCLC)

This is a prospective phase II study designed to evaluate an accelerated and adaptive RT approach for locally-advanced non-small cell lung cancer (NSCLC). All eligible subjects will have an interim PET-CT during radiation therapy to determine the metabolic complete response rate. Radiation therapy will be given in an accelerated fashion (2 Gy/fraction, 6 fractions/week) with concurrent chemotherapy. Interim responses will be assessed using PERCIST criteria.

Despite concurrent chemotherapy and radiation therapy, local/regional failure occurs in ~50% of patients with locally-advanced NSCLC. Clinical studies have demonstrated that accelerated fractionation (giving the same total dose in a shorter period of time) improves outcomes in several malignancies, including lung cancer. Administering higher than conventional doses of RT to all sites of original disease leads to inferior outcomes. Adapting the RT approach, giving a higher dose to slowly responding disease as assessed with interim PET has been shown to be feasible. PERCIST (Positron Emission Tomography Response Criteria in Solid Tumors) provides guidelines on how to report responses to therapy based on PET-CT. PET-CT response has been shown to be prognostic in a variety of clinical scenarios in lung cancer including after induction therapy. In one study, PET was performed after neoadjuvant chemoradiotherapy (40-50.4 Gy). Complete or partial metabolic response using PERCIST criteria was predictive of loco-regional, distant, and overall progression-free survival.

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

Experimental: Carboplatin/Paclitaxel with radiation therapy
Single arm, non randomized, open label study. Eligible subjects will receive standard of care Carboplatin IV once a week, Paclitaxel IV once a week given concurrently with daily hyperfractionated radiation therapy (RT). RT will be delivered as 6 fractions weekly.
Drug: Carboplatin

All subjects will receive 6 fractions(2Gy per fraction) of radiation therapy weekly. All subjects will complete an interim PET-CT after 48Gy-54Gy of RT . Subjects with a complete response on PET will complete RT at 60 Gy; subjects who have residual disease on interim PET and meet strict planning constraints eligibility will proceed to boost RT for a total RT dose of 72Gy. Interim PET-CT response will be measured using PERCIST criteria.
