About this study
Official title: A Prospective, Randomized, Controlled Phase Ⅱ Study of Preventively Use of Methylprednisolone After Split-course Chemoradiotherapy to Reduce the Risk of Radiation-induced Pulmonary Injury For Bulky Local Advanced None-small Cell Lung Cancer
This Phase II randomized controlled study is to determine the efficacy of the preventively use of methylprednisolone after split-course chemoradiotherapy (CCRT) in locally advanced non-small cell lung cancer with bulky tumor.
Read the detailed description
This study is to determine the efficacy of the preventively use of methylprednisolone after split-course chemoradiotherapy(CCRT) in locally advanced non-small cell lung cancer with bulky tumor.
All patients received four cycles of weekly docetaxel (25mg/㎡) and nedaplatin (25mg/㎡)(DP), each of 1 day's duration, combined with split-course thoracic radiotherapy, with one-month break. In the experimental arm, patients were treated with methylprednisolone after the first course of radiation, once a day, 32 milligram (mg) for 7 days, 24 mg for the next 7 days,then 16mg for 7 days, and 8 mg for the last 7 days. Toxicities will be graded according to National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) v. 4.0.

What is being measured
The primary outcome is the main question the study is designed to answer.
rate of grade≥2 radiation pneumonia(NCI-CTC4.0)
radiation-induced pulmonary injury is classified into 1-5 grades according to NCI-CTC4.0. The incidence of symptomatic radiation-induced pulmonary injury: the ratio of grade 2 and above radiation-induced pulmonary injury cases in 1 year after radio therapy to all cases can be evaluated .
Measured: 1 year from the end of radiotherapy
Secondary outcomes (2)
the rate of grade≥2 pulmonary ventilation and diffusion capacity decline
It is divided into grade 1-4 according to SOMA.
Measured: 1 year from the end of radiotherapy
the rate of grade≥2 visible change in CT after radiation
It is divided into grade 1-4 according to SOMA.
Measured: 1 year from the end of radiotherapy

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing chest radiation, concurrent chemotherapy and Methylprednisolone in people with Non-small Cell Lung Cancer, run by Sun Yat-sen University at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 13 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 30 Nov 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was stopped early (reason given: slow enrollment). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
rate of grade≥2 radiation pneumonia(NCI-CTC4.0) (time frame: 1 year from the end of radiotherapy). 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 NCT03661567, which also lists 16 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Nov 2022.
