Proton Beam Radiation With Concurrent Chemotherapy and Nelfinavir for Inoperable Stage III Non Small Cell Lung Cancer (NSCLC)
Condition: Non Small Cell Lung Cancer
MeSH terms: Lung Neoplasms; Carcinoma, Non-Small-Cell Lung
Intervention: Nelfinavir
Intervention description: Two dose levels of Nelfinavir will be evaluated in each concurrent chemotherapy group (carboplatin/paclitaxel and cisplatin/etoposide) at the RPTD does of proton beam radiotherapy: 625 and 1250 mg PO bid.
Intervention MeSH terms: Nelfinavir
Phase: Phase 2
Study type: Interventional
Primary purpose: Treatment
Intervention model: Single Group Assignment
Masking: None (Open Label)
Enrollment: 7.0
Sex: All
Minimum age: 18 Years
Healthy volunteers: No
Keywords: Stage IIIA or IIIB NSCLC

Summary:

      Seventy two patients are being asked to take part in this research study because they have
      been diagnosed with Stage IIIA or IIIB non-small cell lung cancer (NSCLC). This study is
      being done to determine the highest safe dose of proton beam radiotherapy and/or study drug
      (called Nelfinavir) that can be given with concurrent chemoradiotherapy to patients with
      cancer without causing bad side effects; and to develop biomarker for clinical outcome. This
      study will be done in two phases. In the first phase, feasibility will be established. We
      will follow patients treatment courses and record side effects at the standard proton
      radiation dose that can be given together with Cisplatinum + Etoposide or Carboplatin +
      Paclitaxel. In the second phase, we will see if it is possible to increase the total proton
      radiation dose or study drug without increasing the number of bad side effects while treated
      together with chemotherapy drugs.
