Brief summary

Approximately 60 patients will be enrolled with highly suspected lung cancer, or head and neck cancer. The patients must also be starting radiotherapy or a chemoradiotherapy regimen (except with 5-fluorouracil). The patients will undergo 3 visits. One screening, one pre therapy PET/CT imaging visit, and one (3-5 weeks after the start of therapy) post PET/CT imaging visit. This study will evaluate the FLT and FDG images for tumor proliferation rates for early assessment of tumor response to radiation or chemo-radiation combo.

Detailed description

PHASE: II/III OBJECTIVES: Primary: To investigate the clinical value of serial quantitative \[F-18\] FLT positron image assessment of tumor proliferation rates for early assessment of tumor response to radiation or chemoradiotherapy regimens (except with 5-fluorouracil) in comparison to serial quantitative \[F-18\] FDG images Secondary: To gain additional clinical information and experience with \[F-18\]FLT to guide the design of a future, pivotal, Phase III trial where changes in tumor proliferation from pre-treatment baseline values can be used as a early indicator of response to therapy regimens. DESIGN: Open label, nonrandomized, uncontrolled, single group assignment DURATION: Pre treatment \[F-18\] FLT PET scan following a clinical \[F-18\] FDG PET scan followed by post treatment \[F-18\] FLT PET scan and a post treatment, clinical \[F-18\] FDG PET scan at 4 weeks (±1 week) to monitor radiotherapy or chemoradiotherapy. PROCEDURES: Informed consent, collection of demographic information, medical history, physical examinations, vital signs, 12-lead ECGs, concomitant medication collection, monitor adverse events, pre treatment \[F-18\] FLT PET scan and post treatment \[F-18\] FLT PET scan SUBJECTS: Approximately 60 patients will be enrolled with confirmed lung cancer, or head and neck cancer. The patients must also be starting radiotherapy or a chemoradiotherapy regimen (except with 5-fluorouracil) to be eligible. This allows for approximately 40 evaluable patients to complete this study at approximately four to eight sites and conducted in the United States.

Interventions

DRUG[F-18]FLT

The individual doses of \[F-18\]FLT contain a maximum of 10 mCi. The single IP dose is administered to the study subject approximately 30 to 60 minutes prior to the start of PET imaging.

Inclusion criteria

* Patient provides written Informed Consent and is willing to comply with protocol requirements * Patient is at least 18 years of age on the day of dosing (male or female of any race or ethnicity) * Patient is capable of lying still in the PET scanner for the protocol required time frame(s) * Patient has a diagnosis of one of the following malignancies using the TNM Staging System: * Lung cancer (T3 grade up, node positive, but no metastatic disease) * Head and neck cancer (T3 grade up, node positive, but no metastatic disease) * Patient has undergone a comparative, diagnostic procedure with lesion(s) visible, other than ultrasound, that includes, but is not limited to computed tomography (CT), magnetic resonance imaging (MRI), nuclear medicine imaging, endoscopy, laparoscopy, standard abdominal x-ray, biopsy and/or surgery for one of the above mentioned areas * Patient is scheduled to start radiotherapy or a chemoradiotherapy regimen for curative intent * As a part of his/her standard radiotherapy or chemoradiotherapy regimen, patient is scheduled to have clinical \[F-18\]FDG PET scans pre treatment and post treatment (at about 4 weeks (±1 week) after the start of therapy) * Patient is scheduled to have the investigational, pre treatment \[F-18\] FLT PET scan recommended to be within ± 2 days of the clinical, pre treatment \[F-18\] FDG PET scan * Patient has not received or intends to receive 5-fluorouracil (chemotherapeutic agent) * Patient has a score of greater than or equal to (\>/=) 60% on the Karnofsky Performance Status Scale

Exclusion criteria

* Patient is a pregnant or lactating female. Exclude the possibility of pregnancy: * by testing on site at the institution (serum or urine βHCG) within 48 hours prior to the start of each investigational product administration * by surgical history (eg, tubal ligation or hysterectomy) * by patient's history of being post menopausal with a minimum 1 year without menses * Patient is undergoing treatment with palliative intent * Patient has received an investigational compound and/or medical device within 14 days before admission into this study * Patient has any medical condition or other circumstances which would significantly decrease the chances of obtaining reliable data, achieving study objectives, or completing the study and/or post-dose follow-up examinations * Patient is determined by the Investigator that he/she is clinically unsuitable for the study.
