SIB Accelerated Hyperfractionated RT for High-Proliferation NSCLC (HP-SIB-AHFRT)

September 13, 2026 updated by: Second Affiliated Hospital, Zhejiang University, School of Medicine

A Single-arm Phase I/II Clinical Study of Simultaneous Integrated Boost Accelerated Hyperfractionated Radiotherapy for High-proliferation Non-small Cell Lung Cancer

This is a prospective, single-arm, single-center phase I/II clinical trial evaluating the safety, objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) of simultaneous integrated boost accelerated hyperfractionated radiotherapy in patients with high-proliferation non-small cell lung cancer (NSCLC).

Description

Inclusion Criteria:

  1. Age ≥ 18 years, male or female;
  2. Histologically or cytologically confirmed high-proliferation non-small cell lung cancer (NSCLC);
  3. Assessed by a multidisciplinary team (MDT) and planned to receive thoracic radiotherapy (either curative or palliative), regardless of stage.

Exclusion Criteria:

  1. Small cell histology;
  2. Severe cardiac disease (New York Heart Association [NYHA] functional class ≥ III, uncontrolled arrhythmia, or myocardial infarction within the past 6 months);
  3. Pregnant or breastfeeding women, or patients of childbearing potential who are unwilling to use effective contraceptive measures;
  4. Concurrent participation in other interventional clinical trials;
  5. Other conditions deemed by the investigator to make the patient unsuitable for enrollment (e.g., severe mental illness).

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Incidence of Acute Treatment-Related Toxicity
Time Frame: From the start of radiotherapy through 90 days after completion of radiotherapy.
The incidence and severity of acute treatment-related toxicities will be assessed and graded according to the Common Terminology Criteria for Adverse Events (CTCAE), version 5.0.
From the start of radiotherapy through 90 days after completion of radiotherapy.
Incidence of Late Treatment-Related Toxicity
Time Frame: From more than 90 days after completion of radiotherapy through 2 years after completion of radiotherapy.
The incidence and severity of late treatment-related toxicities will be assessed and graded according to the Common Terminology Criteria for Adverse Events (CTCAE), version 5.0.
From more than 90 days after completion of radiotherapy through 2 years after completion of radiotherapy.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Objective Response Rate (ORR)
Time Frame: Every 3 months after completion of radiotherapy, up to 2 years.
Objective response rate is defined as the proportion of participants who achieve a best overall response of complete response (CR) or partial response (PR), as assessed according to Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1.
Every 3 months after completion of radiotherapy, up to 2 years.
Progression-Free Survival (PFS)
Time Frame: From enrollment until documented disease progression or death from any cause, up to 2 years.
Progression-free survival is defined as the time from enrollment to the first documented disease progression or death from any cause, whichever occurs first. Disease progression will be assessed according to RECIST version 1.1.
From enrollment until documented disease progression or death from any cause, up to 2 years.
Overall Survival (OS)
Time Frame: From enrollment until death from any cause, up to 2 years.
Overall survival is defined as the time from enrollment to death from any cause.
From enrollment until death from any cause, up to 2 years.
