Efficacy and Safety of Trastuzumab as a Single Agent in First-Line Treatment of -Overexpressing Metastatic Breast Cancer.

Purpose: To evaluate the efficacy and safety of first-line, single-agent trastuzumab in women with -overexpressing metastatic breast cancer.

Patients And Methods: One hundred fourteen women with -overexpressing metastatic breast cancer were randomized to receive first-line treatment with trastuzumab 4 mg/kg loading dose, followed by 2 mg/kg weekly, or a higher 8 mg/kg loading dose, followed by 4 mg/kg weekly.

Results: The objective response rate was 26% (95% confidence interval [CI], 18.

An open label, single-arm, phase II multicenter study of the safety and efficacy of CG0070 oncolytic vector regimen in patients with BCG-unresponsive non-muscle-invasive bladder cancer: Interim results.

Objectives: CG0070 is a replication-competent oncolytic adenovirus that targets bladder tumor cells through their defective retinoblastoma pathway. Prior reports of intravesical CG0070 have shown promising activity in patients with high-grade non-muscle invasive bladder cancer (NMIBC) who previously did not respond to bacillus Calmette-Guérin (BCG). However, limited accrual has hindered analysis of efficacy, particularly for pathologic subsets.

Phase I/II study of the hypoxia-activated prodrug PR104 in refractory/relapsed acute myeloid leukemia and acute lymphoblastic leukemia.

We previously demonstrated vast expansion of hypoxic areas in the leukemic microenvironment and provided a rationale for using hypoxia-activated prodrugs. PR104 is a phosphate ester that is rapidly hydrolyzed in vivo to the corresponding alcohol PR-104A and further reduced to the amine and hydroxyl-amine nitrogen mustards that induce DNA cross-linking in hypoxic cells under low oxygen concentrations. In this phase I/II study, patients with relapsed/refractory acute myeloid leukemia (n=40) after 1 or 2 prior treatments or acute lymphoblastic leukemia (n=10) after any number of prior treatments received PR104; dose ranged from 1.

PR-104 plus sorafenib in patients with advanced hepatocellular carcinoma.

Purpose: PR-104 is activated by reductases under hypoxia or by aldo-keto reductase 1C3 (AKR1C3) to form cytotoxic nitrogen mustards. Hepatocellular carcinoma (HCC) displays extensive hypoxia and expresses AKR1C3. This study evaluated the safety and efficacy of PR-104 plus sorafenib in HCC.

A phase I trial of PR-104, a nitrogen mustard prodrug activated by both hypoxia and aldo-keto reductase 1C3, in patients with solid tumors.

Purpose: PR-104 is a "pre-prodrug" designed to be activated to a dinitrobenzamide nitrogen mustard cytotoxin by nitroreduction in hypoxic regions of tumors. This study was conducted to establish the maximum tolerated dose (MTD), dose-limiting toxicity (DLT), safety, and pharmacokinetics (PK) of PR-104 in patients with advanced solid tumors.

Methods: Patients with solid tumors refractory or not amenable to conventional treatment were evaluated in a dose-escalation trial of PR-104 administered as a 1-h intravenous (IV) infusion every 3 weeks.

Palifermin reduces the incidence of oral mucositis in patients with metastatic colorectal cancer treated with fluorouracil-based chemotherapy.

Purpose: To characterize the efficacy and safety of palifermin in reducing the incidence of oral mucositis (OM) and diarrhea when administered to patients with metastatic colorectal cancer (CRC) receiving fluorouracil/leucovorin (FU/LV) chemotherapy.

Patients And Methods: Patients (N = 64) were randomly assigned to receive either placebo or palifermin (40 microg/kg for 3 consecutive days) before each of two consecutive cycles of chemotherapy with FU/LV. The incidence of OM and diarrhea, safety, disease progression, and survival were evaluated.

Phase II trial of idiotype vaccination in previously treated patients with indolent non-Hodgkin's lymphoma resulting in durable clinical responses.

Purpose: To evaluate idiotype (Id) vaccination as a single agent in previously treated patients with indolent non-Hodgkin's lymphoma.

Patients And Methods: Patients underwent biopsy for determination of their lymphoma-specific Id sequence. Recombinant Id protein was manufactured and covalently linked with keyhole limpet hemocyanin (KLH) to generate Id/KLH.

Randomized phase I trial of recombinant human keratinocyte growth factor plus chemotherapy: potential role as mucosal protectant.

Purpose: To evaluate the safety of recombinant human keratinocyte growth factor (KGF) when administered with fluorouracil (FU) in patients with metastatic colorectal cancer.

Patients And Methods: Patients (N = 81) received KGF by intravenous (IV) bolus on days 1 to 3, followed by FU 425 mg/m2/d IV bolus plus leucovorin 20 mg/m2/d IV on days 4 to 8. KGF dose levels were 1, 10, 20, 40, 60, and 80 microg/kg/d.

An open label trial of sustained-release cytarabine (DepoCyt) for the intrathecal treatment of solid tumor neoplastic meningitis.

Drugs currently available for intrathecal administration are cleared rapidly from the CSF. DepoCyt is a slow-release formulation of cytarabine that maintains cytotoxic concentrations of free cytarabine in the CSF for >14 days following a single injection. DepoCyt was administered to 110 patients with a diagnosis of neoplastic meningitis based on either a positive CSF cytology (76) or neurologic and CT or MRI scan findings sufficient to document neoplastic meningitis (34).

Phase II trial of weekly paclitaxel in patients with previously treated advanced urothelial cancer.

Purpose: We evaluated the efficacy and toxicity of weekly paclitaxel in patients with previously treated advanced urothelial cancer.

Patients And Methods: Patients with urothelial cancer who had received one prior systemic chemotherapy regimen for advanced disease and had evidence of disease progression were eligible for enrollment. Patients received paclitaxel 80 mg/m(2) by 1-hour intravenous infusion weekly.

Efficacy and safety of trastuzumab as a single agent in first-line treatment of HER2-overexpressing metastatic breast cancer.

Purpose: To evaluate the efficacy and safety of first-line, single-agent trastuzumab in women with HER2-overexpressing metastatic breast cancer.

Patients And Methods: One hundred fourteen women with HER2-overexpressing metastatic breast cancer were randomized to receive first-line treatment with trastuzumab 4 mg/kg loading dose, followed by 2 mg/kg weekly, or a higher 8 mg/kg loading dose, followed by 4 mg/kg weekly.

Results: The objective response rate was 26% (95% confidence interval [CI], 18.

Results from a randomized phase III study comparing combined treatment with histamine dihydrochloride plus interleukin-2 versus interleukin-2 alone in patients with metastatic melanoma.

Purpose: Reactive oxidative species (ROS) produced by phagocytic cells have been ascribed a role in the localized suppression of lymphocyte function within malignant tumors. Histamine has been shown to inhibit ROS formation and possibly synergize with cytokines to permit activation of natural killer cells and T cells. This study was designed to determine whether the addition of histamine to a subcutaneous (SC) regimen of interleukin-2 (IL-2) would improve the survival of metastatic melanoma patients.
