Phase 2a Clinical Trial to Evaluate the Efficacy and Safety of HL301 on Radiation Pneumonitis in Non-small Cell Lung Cancer Patients

A Multicenter, Randomized, Double-blinded, Placebo-controlled, Phase 2a Clinical Trial to Evaluate the Efficacy and Safety of HL301 Versus Placebo on Radiation Pneumonitis in Unresectable Non-small Cell Lung Cancer Patients Treated With Curative Concurrent Chemoradiotherapy Using Paclitaxel and Carboplatin

The purpose of this clinical trial is to evaluate the safety when HL301 is administered to unresectable non-small cell lung cancer patients who receive chemoradiotherapy with Paclitaxel and Carboplatin and to search for a clinically appropriate dose by evaluating the efficacy by comparing the radiation pneumonia incidence rate with the control group.

Inclusion Criteria:

• Male or Female, age ≥ 19 years

• Stage III non-small cell lung cancer(NSCLC) patient who without surgical treatment

• Patients scheduled for curative concurrent chemoradiotherapy

  • chemotherapy : paclitaxel and carboplatin
  • radiation therapy : IMRT, total 60~70Gy

• Eastern Cooperative Oncology Group(ECOG) performance status of 0 to 2 at the screening visit

• Subject whose remaining life expectancy is more than 6 months according to the judgment of investigator

• Volunteer, be willing and able to provide written informed consent for the trial

Exclusion Criteria:

• Subjects with pleural effusion

• Subjects with a weight loss of 10% or more within the last 6 months from the screening visit

• Subjects who administered systemic steroids within 4 weeks prior to the date of randomization (except for cases when administered to prevent hypersensitivity reaction of paclitaxel)

• Subjects who are hypersensitive to investigational products and standard anticancer treatments

• Subjects who participate in other clinical trials within 30 days prior to the screening visit and administer investigational drugs or apply clinical trial medical devices
