简要总结

The goal of this clinical research study is to find the highest safe dose of AMG 531 that can be given to treat thrombocytopenia (low platelet counts) in patients who have received chemotherapy. Researchers will also look at the safety and effectiveness of AMG 531.

Primary Objectives:

  1. To determine the clinical safety and tolerability of AMG 531 administered following chemotherapy (R-HyperCVAD alternating with R-Ara-C/MTX) in patients with non-Hodgkin's lymphoma.
  2. To determine an optimal biologic dose (OBD) of AMG 531 in patients receiving R-HyperCVAD and R-Ara-C/MTX.
  3. To evaluate the effects of AMG 531 on the degree and duration of thrombocytopenia and platelet recovery following chemotherapy(chemo).

Secondary Objectives:

  1. To evaluate limited pharmacokinetics of AMG 531 administered by S.C. route with chemotherapy.

详细描述

Platelets are cells that help make the blood clot. A decrease in platelets can cause bleeding, which may prevent or delay a patient from receiving chemotherapy. R-HyperCVAD (rituximab, cyclophosphamide, vincristine, doxorubicin, and dexamethasone) and R-Ara-C/MTX (rituximab, cytarabine, and methotrexate) are two chemotherapy regimens that are known to increase the risk of lower platelet counts. Researchers want to find out if AMG 531 can lower the risk and severity of this side effect. AMG 531 is a protein that stimulates platelet production.

Before you can start treatment on this study, you will have what are called "screening tests." These tests will help the doctor decide if you are eligible to take part in the study. You will have a complete medical history and physical exam, including measurement of vital signs (temperature, pulse, breathing rate, and blood pressure). You will have blood collected (about 3 teaspoons) for routine tests. Radiologic tests such as CT or MRI scans will be done as needed. Women who are able to have children must have a negative blood pregnancy test.

You will also have about 1 teaspoon of blood drawn to see if the you have antibodies to the study drug.

If you are found to be eligible to take part in this study, you will be randomly assigned (as in the toss of a coin) to one of four treatment groups. These 4 groups will also be split into 2 separate subgroups (Arm A and Arm B). Participants in Arm A will either receive AMG 531 or placebo on Day -5 (5 days before chemotherapy starts) and Day 5 (5 days after chemotherapy starts). A placebo is a substance that looks like the study drug but which has no active ingredients. Every 2 out of 3 participants in Arm A will receive AMG 531. One out of every 3 participants in Arm A will receive placebo.

Participants in Arm B will receive either AMG 531 or placebo on Day 5 and 7. Every 2 out of 3 participants in Arm B will receive AMG 531. One out of every 3 participants in Arm B will receive placebo. The dose of AMG 531 that participants in both Arms A and B receive will depend on when they enroll on the study. There are 3 different dose levels of AMG 531 being studied. Each new group of participants will receive a higher dose than the previous group.

Patients whose therapy was switched to (R)Hyper-CVAD after initial treatment with (R)CHOP, because of aggressive disease will also be eligible for the study.
  • Patients age >/= 18 years.
  • Karnofsky Performance Scale >/=
  • Adequate hematologic (ANC >/= 1000/mm(3), platelet count >/= 100,000/mm(3) and Hgb >/= 8gm/dL), renal (serum creatinine < 2mg/dL), and hepatic functions (total bilirubin </= 2 times, serum glutamate pyruvate transaminase (SGPT) or serum glutamate oxaloacetate transaminase (SGOT) </= 3 times the upper limit of the respective normal range).

结局指标

主要结局

Platelet (PLT) Nadir

时间窗: Prior to start of treatment and then at least 2 times a week during treatment until end of cycle 2 (1 cycle = 21 days)

Blood counts were performed at least two times a week and when clinically indicated during the study and daily when PLT count is \< 50K/μL until recovery (two consecutive counts showing upward trend). The optimal biologic dose was defined as the dose of AMG 531 at which the greatest proportion of patients avoided grade 4 thrombocytopenia (Platelet nadir \< 25K/μL) in the absence of platelet transfusion in the blinded study cycle.

Days Platelets Count of < 100K/μL

时间窗: Prior to start of treatment and then at least 2 times a week during treatment until end of cycle 2 (1 cycle = 21 days)

The optimal biologic dose was defined as the dose of AMG 531 at which the greatest proportion of patients avoided grade 4 thrombocytopenia (Platelet nadir \< 25K/μL) in the absence of platelet transfusion in the blinded study cycle.
