Radiation Therapy (XRT) and ZD6474 in Non-Small Cell Lung Cancer (NSCLC)

• Status: Terminated
• Trial end date: 2012-09-01
• Target enrollment: 0
• Participant gender: All

Summary

Primary Objectives:

• To assess the safety of oral therapy with ZD6474 by evaluating the frequency, severity, and duration of treatment-emergent adverse events in patients with poor prognosis lung cancer.

• To record the extent, frequency and duration of any tumor responses to this treatment regimen and assess whether ZD6474 augments the efficacy of radiation therapy in non-small cell lung cancer patients.

• To determine the recommended phase II dose of ZD6474 for future clinical studies with radiation therapy.

Secondary Objectives:

• To determine the effects on metabolism and angiogenic factors by positron emission tomography (PET) scan/computed tomography (CT) scan , vascular endothelial growth factor (VEGF), and circulating endothelial cell levels in patients treated with ZD6474 and radiation therapy.

• Phase: Phase 1
• Accepts Healthy Volunteers?: No

9. aspartate aminotransferase-alanine aminotransferase (AST/ALT) < 2.5 upper limit of normal (ULN) or alk phos (ALP) < 2.5 * ULN, or < 5* ULN if judged by the investigator to be related to liver metastases

10. Total bilirubin < 1.5 * ULN or <3 * ULN if related to liver metastases

11. Serum creatinine < 1.5 * Upper Limit of the Reference Range (ULRR) or creatinine clearance greater than or equal to 50 mL/minute (calculated by Cockcroft-Gault formula.)

14. Potassium must be within normal laboratory value range. Serum calcium and magnesium must be within normal range. Supplementation may be used to normalize.

15. Patients with distant metastases and life expectancy greater than or equal to 3 months are eligible.

16. Due to the experimental nature of ZD6474, female patients must be one year post-menopausal, surgically sterile, or using an acceptable method of contraception (oral contraceptives, barrier methods, approved contraceptive implant, long-term injectable contraception, intrauterine device or tubal ligation.) Male patients must be surgically sterile or using an acceptable method of contraception during their participation in this study.

17. A negative pregnancy test within 72 hours prior to administration of ZD6474 will be required for women of childbearing potential.

18. Patients must sign an informed consent indicating that they are aware of the investigational nature of the study in keeping with the policy of M.D. Anderson Cancer Center. Patients must also agree to study restrictions and return for required assessments. The only approved consent form is attached to this protocol.

19. Eligibility for Phase II: (A) Patients with medically inoperable stage I and II non-small cell lung cancer for whom definitive XRT alone is recommended (not candidate for combined chemo-XRT), or, (B) Patients who received previous induction chemotherapy off protocol, not candidates for other chemo-XRT protocols, or, (C) Patients with stage III NSCLC for whom definitive XRT alone is recommended, or, (D) Patients with any stage for whom palliative radiation therapy to 45 Gy/15 Fx is recommended.

20. Patients who are blood donors should not donate blood during the trial and for 3 months following their last dose of trial treatment.

Exclusion Criteria:

1. Pregnancy or breast feeding

2. Bronchoalveolar carcinoma

3. Oxygen saturation less than 90% on room air or requirement for oxygen supplementation

4. Any condition that is likely to interfere with regular follow-up

5. Patient cannot have participated in any clinical trial involving conventional or investigational drugs within 4 weeks prior to administration of ZD6474

6. Patient cannot have received radiation therapy or chemotherapy within 4 weeks prior to administration of ZD6474 (6 weeks for nitrosoureas and mitomycin)

12.
