|Official Title:||A Phase I/II Clinical Trial of Intravenous (IV) Calcitriol With Fixed Dose of Cisplatin and Docetaxel in Advanced Non-Small Cell Lung Cancer|
|Study Start Date :||December 2008|
|Actual Primary Completion Date :||October 2011|
|Actual Study Completion Date :||August 2013|
In the Phase I part of the study, we will test the safety of calcitriol along with standard chemotherapy. In addition, the goal is to see what effects (good and bad) it has on you and your type of Non-Small Cell Lung Cancer. This study is ongoing. In this portion of the study, we are testing increasing doses of calcitriol in combination with standard chemotherapy. If 2/3 patients at any dose level experience side effects that are limiting, we will call the dose level below that dose the maximum tolerated dose.
Escalating dose of Calcitriol will be infused IV over 1 hour every 21 days.
In the Phase II part of the study, we will find out the response of subjects' cancer has to the combination of a fixed dose of calcitriol (determined in the phase I study) with standard chemotherapy.
In this portion of the study, all patients will get the same dose of calcitriol (determined from the Phase I study) along with the standard chemotherapy
- MTD of Intravenous Calcitriol When Administered Prior to Fixed Dose Cisplatin 75mg/m2 and Docetaxel 75 mg/m2, Every 3 Weeks in Patients With Advanced Non-small Cell Lung Cancer (NSCLC) [ Time Frame: 5 years ]The primary objective was to determine the Maximum Tolerated Dose (MTD) of intravenous calcitriol when administered prior to fixed dose cisplatin 75mg/m2 and docetaxel 75 mg/m2, every 3 weeks in patients with advanced non-small cell lung cancer (NSCLC). Accrual duration for the study is 5 years.
- Number of Participants That Experience Grade 3 or Greater Neutropenia [ Time Frame: 30 days after last dose ]The second primary objective was to characterize the toxicity and response of patients treated with a combination of calcitriol, cisplatin and docetaxel. Toxicity was assessed, in part, by noting the number of participants that experience grade 3 or greater neutropenia in each phase of the trial. Toxicities were recorded using NCI CTCAE (Common Terminology Criteria for Adverse Events) version 3.0 and were followed for 30 days after the date of withdrawal from study drug.
- Median Time to Progression [ Time Frame: 5 years ]The second primary objective was to characterize the toxicity and response of patients treated with a combination of calcitriol, cisplatin and docetaxel. To assess the response, median time to progression was determined. Progression was defined as at least a 20% increase in the sum of the longest diameter of target lesions, taking as reference the smallest sum longest diameter recorded since the treatment started or the appearance of one or more new lesions.
- Median Overall Survival [ Time Frame: 5 years ]The second primary objective was to characterize the toxicity and response of patients treated with a combination of calcitriol, cisplatin and docetaxel. To assess the response, overall survival was determined.
- Mean AUC 1,25-D3 Concentration at 12 and 24 Hours [ Time Frame: 12 and 24 hours post dose ]The mean AUC (area under the curve) concentrations of 1,25-D3 from 0-12 hours and 0-24 hours will be calculated.
- To Correlate the Pharmacokinetic Parameters of Systemic Calcitriol Exposure (AUC) With SNPs of the 24-hydroxylase (CYP24), the Major Vitamin D3 Inactivating Enzyme. [ Time Frame: 3-6 months ]
