|Tumors Unknown Primary Tumors Adenocarcinoma||Drug: Capecitabine Drug: Carboplatin Drug: Paclitaxel||Phase 1 Phase 2|
Rationale: The combination of the chemotherapy drugs paclitaxel and carboplatin is one of the most common combination regimens used in clinical practice for cancer. These agents are used for a variety of cancers. The current study builds on previous research about treatment schedules for administering these agents to reduce toxicity and optimize efficacy. The phase I and II portions of the current study combine paclitaxel and carboplatin with capecitabine in patients. Researchers are seeking to identify the highest dose of capecitabine and paclitaxel in combination with carboplatin for this patient population, as well as to gather information about preliminary efficacy.
Purpose: The phase I portion of this study will evaluate the maximum tolerated dose of capecitabine and paclitaxel in combination with carboplatin for patients. The phase II portion of this study will assess the objective response rate in patients using the same treatment combination. Toxicities will be closely measured in both phases of the study.
Treatment: Patients in this study will be given capecitabine, carboplatin, and paclitaxel. Capecitabine will be given through oral pills. Carboplatin and paclitaxel will be given through intravenous infusions. Treatment drugs will be given on a four-week cycle. Carboplatin will be administered on day 1, paclitaxel weekly for the first 3 weeks, and capecitabine twice daily on days 8 through 21 of each cycle. No treatments will be given during the fourth week of each treatment cycle. During the phase I portion of the study, patients may receive different doses of capecitabine and paclitaxel since the purpose is to identify the maximum tolerated dose of each drug in combination with carboplatin. Once the maximum tolerated dose of these agents is identified during phase I, the phase II portion of the study will begin. Treatments will be discontinued due to disease growth or unacceptable side effects. Several tests and exams will be given throughout the study to closely monitor patients.

|Official Title:||A Phase I Dose Escalation Study of Capecitabine, Carboplatin and Weekly Paclitaxel and a Phase II Trial of the Same Combination in Patients With Adenocarcinoma of Unknown Primary|
|Study Start Date :||June 2005|
|Actual Primary Completion Date :||November 2007|
|Actual Study Completion Date :||June 2013|
Experimental: Arm I
Patients receive paclitaxel IV over 60 minutes on days 1, 8, and 15, carboplatin IV over 1-2 hours on day 1, and capecitabine PO BID on days 8-21. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Level 1: 500 mg/m2 orally twice daily Days 8 - 21 of each cycle. Level 2: 750 mg/m2 orally twice daily Days 8 - 21 of each cycle. Level 3 - 5: 1000mg/m2 orally twice daily Days 8 - 21 of each cycle.
Other Name: Xeloda
Levels 1-5: AUC of 6 every 4 weeks.
Level 1-3: 60 mg/m2/week. Level 4: 80 mg/m2/week. Level 5: 100 mg/m2/week.
- Maximum Tolerated Dose in Phase I Portion of Study [ Time Frame: Every 3 weeks, for up to 24 weeks ]Determine the maximum tolerated dose of the triplet combination of capecitabine that can be administered in combination with weekly paclitaxel and every four weeks carboplatin.
- Objective Response Rate (ORR) for the Phase II Portion of the Study. CR+PR Per RECIST v1.0 Criteria Using a Single Arm , Two Stage Minimax Design. [ Time Frame: Every 3 weeks, for up to 24 weeks ]Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR
- Phase I: To Determine Side Effects [ Time Frame: Every 3 weeks, for up to 24 weeks ]The common clinically significant grade 3 and 4 toxicities graded using the National Cancer Institutes Common Toxicity Criteria version 3.0
- Progression-Free Survival at 6 Months for Patients [ Time Frame: up to 6 years ]For patients enrolled on the Phase II portion of the trial Progression Free Survival (PFS) was measured from the percentage of patients that were still alive, without evidence of disease progression for 6 months following the initiation of treatment. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions
- One Year Survival for Patients [ Time Frame: Up to 1 year ]For patients enrolled on the Phase II portion of the trial the One-year survival was measured as the percentage of patients alive 1 year after their treatment in the trial.
- Time to Tumor Progression for Patients [ Time Frame: Up to 6 years ]For patients enrolled on the Phase II portion of the trial the time to progression was measured as the time from when the patient started treatment to the time the patient is first recorded as having disease progression or the date of death if the patient dies due to causes other than disease progression.
