Study summary

This is a single arm seamless phase I/II prospective cohort study. Patients with early stage Non-Small Cell Lung Cancer (T1-T2N0M0) or those with a single pulmonary metastasis of a known malignancy (either following radical treatment or systemic therapy) will be offered participation in this study. Participants will have three tumor locator beacons placed with a flexible bronchoscope in the small bronchial airways in proximity (\<3cm) from their lung tumors. These tumor locator beacons will provide real-time positional data and will allow for smaller treatment volumes of Stereotactic Ablative Radiosurgery (SABR) and also allow for a specialized form of treatment delivery known as respiratory gated SABR. This is expected to result in higher precision radiotheapy delivery with less radiotherapy dose to healthy tissues which are in close proximity to the lung tumours.

Read the detailed description

This trial is a seamless phase I/II prospective, single arm, cohort study.

Phase I of the trial will consist of two patients and will serve to conduct quality assurance assessments and to familiarize thoracic surgeons, radiation oncologists, and medical physicists at CancerCare Manitoba and Health Sciences Center in the use and work flow of the Health Canada approved endobronchial implanted real-time tumor tracking transponder beacons. Patients in phase I will undergo standard stereotactic ablative radiotherapy (SABR) of a lung tumor with prior endobronchial transponder beacon placement. For phase I, the transponder beacons will be used for comparative localization analyses and SABR treatment setup procedures will be carried out independent of transponder beacon data, however, transponder data will be collected in order to conduct, post-treatment, in vivo quality assurance assessments of beacon performance characteristics. Otherwise, the SABR treatment for phase I will consist of the currently accepted standard internal target volume based and standard image guided SABR.

Phase II of this trial will consist of 26 patients who will undergo a specialized form of SABR radiotherapy specifically designed to take full advantage of the real-time tumor tracking ability of the transponder beacons. Specifically, SABR in phase II will consist of smaller radiotherapy treatment volumes employing respiratory gating and smaller planning target volume expansion margins given the superior tumor location telemetry afforded by the beacons. Comparative dosimetric analyses contrasting the traditional ITV/PTV style treatments to those with reduced ITV/PTV margins achieved via Calypso guided SABR will be performed. Patient self-reported quality of life and toxicity assessments will be collected with the goal of facilitating power and sample size calculations for the design of a larger phase III randomized controlled trial of Calypso guided SABR treatment in the future

    2. Minimum DLCO of 35% predicted.
  9. Able to provide written and understand verbal instructions necessary for radiotherapy treatments.

Exclusion criteria

Exclusion Criteria:

  1. Tumors located \< 1cm from the chest wall based on CT imaging.
  2. Tumors located ≤ 2 cm from the proximal bronchial tree (see figure 7)
  3. Patients who require supplemental oxygen at rest.

Terms in these criteria, in plain language(8)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

FEV1

From a breathing test (spirometry): how much air you can blow out in the first second. Often given as a percentage of what is expected for your age, height and sex.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Study arms

  • Experimental
    Real-Time Position Transponder Beacons

    Patients in this arm will each be receiving 3 implanted real-time position transponder beacons (Calypso beacons)

    Device: Real-Time Position Transponder Beacons

Interventions

  • DeviceReal-Time Position Transponder Beacons

    The anchored lung tracking beacons are passive electromagnetic transponder beacons which are placed immediately adjacent to a lung tumor using a bronchoscope. Three beacons will be placed in the small airways of the lung adjacent to the target tumor (within 3 cm of the tumor). Each beacon measures 2 mm in diameter and 8 mm in length and consists of a miniature electrical circuit that is encapsulated in a biocompatible glass capsule. Each beacon has an affixed five-legged anchoring system which expands to 5mm diameter once deployed. The Calypso transponder beacon is placed endobronchially using the working channel of a bronchoscope. Navigational bronchoscopy can be used to pre-plan the optimal location for each beacon to be placed within the airways by using a pre-bronchoscopy CT scan.
