  Description
Phase 1

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.

Calcitriol: Escalating dose of Calcitriol will be infused IV over 1 hour every 21 days.

Phase 2

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.

Calcitriol: 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

  Baseline Characteristics

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
Thirty-four patients were enrolled (18 in phase I and 16 in phase II).

Reporting Groups
  Description
