Purpose: This study evaluated the clinical relevance of the dual-targeting strategy involving PI3K/AKT/mTOR and RAF/MEK/ERK pathways.
Experimental Design: We investigated safety, efficacy, and correlations between tumor genetic alterations and clinical benefit in 236 patients with advanced cancers treated with phase I study drugs targeting phosphoinositide 3-kinase (PI3K) and/or mitogen-activated protein kinase (MAPK) pathways in our Phase I Clinical Trials Program.
Results: Seventy-six (32.
Purpose: The purpose of this study was to assess the feasibility of administering Ad5CMV-p53, an adenoviral vector containing the wild-type p53 gene to patients with advanced malignancies, characterize the pertinent pharmacokinetic parameters, identify evidence of viral uptake in both normal and tumor tissue, and seek evidence of antitumor activity.
Methods: Patients were treated with escalating doses of Ad5CMV-p53 intravenously over 30 minutes on days 1, 2, and 3, every 28 days. The clearance of circulating Ad5CMV-p53 (INGN 201) DNA was characterized in the plasma and paired tumor and skin biopsies were performed in patients treated at the two highest dose levels to assess vector uptake into tissues.
Purpose: To assess the feasibility of administering oblimersen sodium, a phosphorothioate antisense oligonucleotide directed to the Bcl-2 mRNA, with docetaxel to patients with hormone-refractory prostate cancer; to characterize the pertinent pharmacokinetic parameters, Bcl-2 protein inhibition in peripheral blood mononuclear cell(s) (PBMC) and tumor; and to seek preliminary evidence of antitumor activity.
Experimental Design: Patients were treated with increasing doses of oblimersen sodium administered by continuous i.v.
Purpose: This study was conducted to assess the feasibility of administering the oral diarylsulfonylurea (DSU) ILX-295501 on a weekly for 3 weeks every 4-week schedule. The study also sought to determine the maximum tolerated dose (MTD) of ILX-295501 on this schedule, characterize its pharmacokinetic behavior, and seek preliminary evidence of anticancer activity.
Experimental Design: The initial starting dose of ILX-295501 was 100 mg/m(2), which was equivalent to one-sixth of the highest dose that did not induce irreversible toxicity in dogs, and, using a modified Fibonnaci search scheme to guide dose level selection, the following dose levels were evaluated: 100, 200, 400, 600, 900, 1350, and 1800 mg/m(2).
