3-AP and Gemcitabine in Treating Patients With Advanced Solid Tumors or Lymphoma

National Cancer Institute (NCI)30 enrolled

Overview

This phase I trial is studying the best dose of 3-AP and the side effects of giving 3-AP together with gemcitabine in treating patients with advanced solid tumors or lymphoma. Drugs used in chemotherapy, such as 3-AP and gemcitabine (GEM), work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. 3-AP may help gemcitabine kill more cancer cells by making the cells more sensitive to the drug. 3-AP may also stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

PRIMARY OBJECTIVES: I. To determine the maximal tolerable dose (MTD) of 3-AP administered as a 24 hour infusion in combination with and fixed-dose gemcitabine hydrochloride (GEM) in patients with advanced solid tumors or lymphomas. SECONDARY OBJECTIVES: I. To define the qualitative and quantitative toxicities of the 3-AP/GEM combination in regard to organ specificity, time course, predictability, and reversibility. II. To document the therapeutic response of this combination in those patients when possible. III. To measure deoxycytidine triphosphate (dCTP) levels in peripheral blood mononuclear cells (PBMCs) before and after treatment at specified times and try to correlate findings to activity and toxicity of 3-AP. IV. To perform limited pharmacokinetic analysis. OUTLINE: This is a dose-escalation study of 3-AP (Triapine®).Patients receive 3-AP (Triapine®) IV over 24 hours followed by gemcitabine hydrochloride IV over 100-125 minutes on days 1 and 8. Treatment repeats every 3 weeks for 12 courses in the absence of disease progression or unacceptable toxicity. Patients achieving complete response (CR) receive 1 additional course of therapy beyond documented CR.Cohorts of 3-6 patients receive escalating doses of 3-AP (Triapine®) until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.After completion of study treatment, patients are followed periodically for 2 years.

Outcomes

Primary Outcomes

MTD as assessed by the number of patients with dose-limiting toxicity (DLT)

MTD is the maximum dose level with fewer than 2 of 3/6 patients experiencing DLT. The study uses standard method phase I design of dose escalation. DLT will be defined as greater or equal to Grade 3 non-hematologic or greater or equal to Grade 4 hematologic adverse event EXCEPT: greater or equal to Grade 3 nausea and greater or equal to Grade 3 vomiting that improves with antiemetic therapy; greater or equal to Grade 3 diarrhea that improves with Lomotil; and greater or equal to Grade 4 Neutropenia that recovers to less or equal to Grade 3 within 7 days of first identification.

Time frame: Observed clinically for 4 hours after each 3-AP infusion during the first cycle of treatment

Secondary Outcomes

Toxicity as assessed using the NCI Common Toxicity Criteria, Version 3.0

Toxicities include neutropenia grade 4 (\<500/mm3), neutropenic fever (grade 4 neutropenia and greater than or equal to grade 2 fever), thrombocytopenia Grade 3-4 (\<50000/mm3), and non-hematologic toxicities grades 3-4. The descriptions and grading scales found in the revised NCI Common Terminology Criteria for Adverse Events (CTCAE) version 3.0 will be utilized for adverse event reporting.

Time frame: Observed clinically for 4 hours after each 3-AP infusion during the first cycle of treatment and monitored until disease progression or for a maximum of 24 months following termination of treatment

Therapeutic response

Response and progression will be evaluated in this study using the new international criteria proposed by the Response Evaluation Criteria in Solid Tumors (RECIST) Committee. Complete Response (CR) is the disappearance of all target lesions. Partial Response (PR) requires at least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD. The results will be purely descriptive.

Time frame: Tumor and radiologic measurements every 8 weeks from start of treatment. In addition to a baseline scan, confirmatory scans will also be obtained 8 weeks following initial documentation of an objective response.

Duration of overall response

The duration of overall response is measured from the time measurement criteria are met for CR or PR (whichever is first recorded) until the first date that recurrent or progressive disease is objectively documented (taking as reference for progressive disease the smallest measurements recorded since the treatment started).

Time frame: Baseline until disease progression or for a maximum of 24 months following termination of treatment.

Duration of stable disease

Stable disease is measured from the start of the treatment until the criteria for progression are met, taking as reference the smallest measurements recorded since the treatment started.

Time frame: Baseline until disease progression or for a maximum of 24 months following termination of treatment.

Levels of dCTP in PBMCs correlated to activity and toxicity of 3-AP

If dCTP levels are diminished by 3-AP, there is a real possibility of ribonucleotide reductase (RR) inhibition in tumor cells with a higher growth fraction (known to have elevated RR levels). It will also be possible to correlate the steady state levels of 3-AP with the concentration of dCTP in circulating cells. The RT-PCR of PBMCs before and after infusion would be helpful to reassure that the change of dCTP pool is correlated with 3-AP inhibiting RR.

Time frame: PMBCs isolated immediately before and after 3-AP infusion (day 1), but before GEM is started on (day 2) on both course 1 and course 2 of treatment

Pharmacokinetics as assessed by steady state concentration (Css) of 3-AP in serum

Time frame: On the first day of infusion (course 1 only) during the last 4 hours of 3-AP infusion
