About

The purpose of this study is to determine whether TH-302 in combination with pemetrexed is safe and effective in the treatment of non-squamous non-small cell lung cancer.

Full description

TH-302 is designed to target the hypoxic regions of tumors which are generally located distant from tumor vessels. Pemetrexed has poor tissue penetration and targets the regions of tumors that are located in proximity to the tumor vessels. The presence of hypoxia in solid tumors is associated with a more malignant phenotype and resistance to chemotherapy. The hypoxia-activated prodrug, TH-302, is designed to selectively target the hypoxic microenvironment. There is evidence supporting the presence of hypoxia in NSCLC lesions based on a hypoxia PET study. Combining pemetrexed with TH-302 may enable the targeting of both the normoxic and hypoxic regions of NSCLC lesions.

Inclusion criteria

Men and women ≥ 18 years of age.
Histologically or cytologically confirmed stage IIIB or IV NSCLC with non-squamous histology
Recurrent or progressive disease after one prior platinum-based non-pemetrexed chemotherapy treatment for advanced disease with or without maintenance
Neoadjuvant/adjuvant cytotoxic chemotherapy initiated < 12 months prior to study randomization will be counted as one prior treatment
Neoadjuvant/adjuvant cytotoxic chemotherapy initiated ≥ 12 months prior to study randomization will not be counted as one prior chemotherapy treatment
Use of targeted agents (e.g., monoclonal antibodies or kinase inhibitors) will not be counted as a prior chemotherapy treatment
Patients with known EGFR-activating mutations or ALK rearrangements should have received treatment with a targeted kinase inhibitor (e.g., erlotinib, crizotinib) and no longer be considered as a candidate for such treatment
Measurable disease according to RECIST 1.1
ECOG performance status 0-1
Resolution to Grade ≤ 1 Adverse Events, of all clinically significant toxic effects of prior therapy
Adequate hematologic, hepatic, cardiac, and renal function
Female patients of childbearing potential must have a negative serum or urine pregnancy test, whichever is considered standard by the institution
