|Adult Solid Neoplasm||Dietary Supplement: Calcitriol Drug: Cisplatin Drug: Gemcitabine Hydrochloride Other: Pharmacological Study||Phase 1|
I. To determine the maximum tolerated dose of oral calcitriol when combined with a standard dose of gemcitabine (gemcitabine hydrochloride) and cisplatin in a 28-day cycle.
I. Describe the toxicity of this combination using Common Terminology Criteria for Adverse Events (CTCAE) version 4.0.
II. Study the pharmacokinetics of calcitriol at the maximum tolerated dose (MTD) in an expanded cohort of 6 patients.
III. Describe the clinical activity associated with this regimen in this advanced solid tumor population.
Patients receive calcitriol orally (PO) on days 1, 2, 8, 9, 15 and 16; cisplatin intravenously (IV) over 2 hours on day 2; and gemcitabine hydrochloride IV over 30 minutes on days 2, 9, and 16. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days.

Experimental: Treatment (calcitriol, cisplatin, gemcitabine hydrochloride)
Patients receive calcitriol PO on days 1, 2, 8, 9, 15 and 16; cisplatin IV over 2 hours on day 2; and gemcitabine hydrochloride IV over 30 minutes on days 2, 9, and 16. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Dietary Supplement: Calcitriol
Drug: Gemcitabine Hydrochloride
Other: Pharmacological Study
Other Name: pharmacological studies
- MTD of oral calcitriol when combined with a standard dose of gemcitabine hydrochloride and cisplatin, determined according to incidence of dose-limiting toxicity, graded using the National Cancer Institute (NCI) CTCAE version 4.0 [ Time Frame: 28 days ]A standard 3+3 with de-escalation will be used to estimate the MTD.
- Toxicity of this combination, graded according to NCI CTCAE version 4.0 [ Time Frame: Up to 30 days after last dose of study drug ]Tabulated overall or by dose level (as appropriate).
- Pharmacokinetic (PK) analyses of calcitriol at the MTD in an expanded cohort of 6 patients, including peak levels, area under the concentration-time curve from time 0-72 hours, terminal half-life, volume of distribution, and total body clearance [ Time Frame: Days 1-3 of course 1 ]PK data will be presented as plots of serum calcitriol concentration over time for each patient. An assessment of whether systemic calcitriol exposure associated with antitumor activity in preclinical models is achieved in these patients will be made.
- Objective tumor response, described using Response Evaluation Criteria in Solid Tumors 1.1 [ Time Frame: Up to 5 years ]Responses tabulated as appropriate.
