Phase 1

Completed

• Conditions: Lung Diseases; Cancer
• Interventions: Drug: Combination Treatment - Cohort 1; Drug: Combination Treatment - Cohort 2; Drug: Combination Treatment - Cohort 3; Drug: Combination Treatment - Cohort 4

• Registration Number: NCT00249964
• Lead Sponsor: New Mexico Cancer Care Alliance

Brief Summary

The purpose of this study is to determine the maximum tolerable dose of temozolomide in combination with fixed dose of paclitaxel and carboplatin and to determine the overall tumor response rate with this combination and to determine the duration of response.

Detailed Description

The objective of the research study is to test a combination of drugs to treat small cell lung cancer which has spread beyond the lungs (extensive cancer) or come back after earlier treatment (recurrent cancer).

Exclusion Criteria

1. No recovery from all active toxicities of prior therapies.
2. Subjects who are poor medical risks because of non-malignant systemic disease as well as those with acute infection treated with intravenous antibiotics.
3. Frequent vomiting or medical condition that could interfere with oral medication intake (eg, partial bowel obstruction).
4. Concurrent malignancies at other sites with the exception of surgically cured carcinoma in-site of the cervix and basal or squamous cell carcinoma of the skin. Prior malignancies which have not required anti-tumor treatment within the preceding 24 months are eligible.

8. Men who are not advised to use an effective method of contraception.
9. Progression of disease on prior chemotherapy with paclitaxel and carboplatin, either as single agent or in combination.
10. Known hypersensitivity reaction to taxoid or platinum compound.

Primary Outcome Measures

Name	Time	Method
Maximum Tolerated Dose of Temozolomide in Combination with Fixed Doses of Paclitaxel and Carboplatin	4 months	Temozolomide was administered at different dose levels (see Cohorts 1-4) until the maximum tolerated dose (MTD) was reached. MTD is the dose at which 0/6 or 1/6 patients in the cohort experience dose limiting toxicity (DLT) during the first 4 week cycle with the next higher dose having at least 2/3 or 2/6 patients experiencing DLT. DLT will have occurred when the patient has 1 or more Grade 4 hematologic or nonhematologic toxicities. A DLT must occur in the first cycle of the combination and must be at least possibly attributed to the treatment regimen. Toxicities will be graded according to the NCI CTCAE Version 3.0.

Secondary Outcome Measures

Name	Time	Method
Tumor response rate	7 months	Tumor response is evaluated according to Response Evaluation Criteria In Solid Tumors (RECIST) version 1.0 as determined by the investigator. Complete response (CR): Disappearance of all evidence of target and non-target lesions. Partial response (P): \>= 30% reduction from baseline in the sum of the longest diameter of all lesions. CR and PR criteria should be met again after 4 weeks and before 6 weeks after initial assessment. Stable Disease (SD): Neither sufficient increase to qualify for PD nor sufficient shrinkage to qualify for PR. Progressive disease (PD) for target lesions: \>= 20% increase in the sum of diameters of the target lesions taking as reference the smallest sum on study, and an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered . PD for non-target lesions is defined as unequivocal appearance of one or more new malignant lesions or unequivocal progression of existing non-target lesions.
