Clinical trial enrollment is impeded by the significant time burden placed on research coordinators screening eligible patients. With 50,000 new cancer cases every year, the Veterans Health Administration (VHA) has made increased access for Veterans to high-quality clinical trials a priority. To aid in this effort, we worked with research coordinators to build the MPACT (Matching Patients to Accelerate Clinical Trials) platform with a goal of improving efficiency in the screening process.

The COVID-19 pandemic posed unprecedented strain on enrollment to cancer clinical trials and their conduct. Here, we highlight an analysis using information from the National Cancer Institute (NCI) Clinical Trials Reporting Program database to describe enrollment patterns to interventional cancer treatment trials at NCI-Designated Cancer Centers during the pandemic. Enrollment to cancer treatment trials at NCI-Designated Cancer Centers decreased precipitously early in the pandemic and has not yet fully returned to the 2019 baseline as of mid-2021.

Methods: Patients with stage III/IV EOC received cyclophosphamide 750 mg/m(2), followed by a 24-hour infusion of paclitaxel 250 mg/m(2) and cisplatin 75 mg/m(2) on Day 2. Filgrastim began on Day 3 at 10 microg/kg daily for 9 days.
Background: We previously reported preliminary results of our phase I study of continuous daily sorafenib with bevacizumab every other week for solid tumours. Toxicity was moderate, leading to additional dose levels (DL) testing intermittent sorafenib dosing.
Methods: Seventeen patients with advanced solid tumours were treated on three additional DLs testing sorafenib days 1-5 per week.
Background: Carboxyamido-triazole (CAI) is a calcium influx inhibitor with anti-angiogenic and anti-invasive properties and stabilizes tumor progression in patients. We hypothesized daily oral micronized CAI with q3 week paclitaxel would be well-tolerated and active.
Results: Twenty-nine heavily pretreated patients [median 3 [0-7]] were enrolled on five dose levels.
Purpose: Sorafenib inhibits Raf kinase and vascular endothelial growth factor (VEGF) receptor. Bevacizumab is a monoclonal antibody targeted against VEGF. We hypothesized that the complementary inhibition of VEGF signaling would have synergistic therapeutic effects.

Experimental Design: Colony-forming assays were used to test the activity of CAI plus PAX on A2780 human ovarian cancer. The sequence of CAI followed by PAX (CAI>Pax) was modeled in nude mice to test for potential additive toxicity.
Despite the known association of these malignancies, the incidence of a synchronous presentation of breast and ovarian cancer is low, and the current literature does not address an approach to this clinical problem directly. We report a greater than 2.5 year disease-free survival in a patient treated for synchronous stage IIIB inflammatory breast cancer and stage IIIC epithelial ovarian cancer.

The use of taxanes in the current gynecologic-oncologic clinical setting is reviewed with special consideration given to the pharmacokinetics of taxane in relation to dose intensity and length of administration.

Methods: The authors treated 26 consecutive, newly diagnosed patients with International Federation of Gynecology and Obstetrics (FIGO) Stage III/IV AOC with carboplatin, 600 mg/m2, on Day 1; cyclophosphamide, 250 mg/m2, on Day 1; and cisplatin, 100 mg/m2, on Day 8 every 4 weeks with or without pretreatment with amifostine (range, 740-1140 mg/m2). Platinum dose intensity was estimated using a 4:1 conversion for equipotent doses of cisplatin and carboplatin for expression as cisplatin dose equivalents (CDE).
Purpose: Cytostatic agents targeted against angiogenesis and tumor cell invasive potential form a new class of investigational drugs. Orally administered carboxyamidotriazole (CAI) (NSC609974) is both antiangiogenic and antimetastatic. An encapsulated micronized powder formulation has been developed to optimize CAI administration.

Based on these data we initiated a phase I clinical trial in patients with refractory metastatic cancer. This report characterizes the pharmacokinetic profile of both the total plasma concentrations of elemental platinum and the unbound ultrafiltrate concentrations of elemental platinum, following a 30 min intravenous infusion of ormaplatin.

This tumor often is associated with a significantly better prognosis than epithelial ovarian cancer. Most tumors are either serous or mucinous in histology and present as early stage lesions.

We investigated the addition of dose-intense paclitaxel to cisplatin and cyclophosphamide for patients with FIGO III/IV epithelial ovarian cancer. Paclitaxel dose was intensified from 135 to 250 mg/m2 and administered in combination with cisplatin at > or = 75 mg/m2 and cyclophosphamide at 750 mg/m2.

This was done to take advantage of the cellular and molecular synergism between paclitaxel and DNA-damaging agents, with the hope of avoiding paclitaxel-cisplatin toxicities. Paclitaxel was given as a 24-hr CIVI, after which cyclophosphamide was given as a 60-min infusion.

Inhibition of calcium influx and calcium-dependent events is a potential common mechanism underlying these effects of CAI. The cytostatic and antiangiogenic properties of CAI led to its development for clinical investigation.

We have analyzed available phase II data in these two diseases, to assess the possibility that paclitaxel dose intensity may be important in the induction of disease response. When analyzed by the methods developed by Hrynuik and Levin, available data suggest that the relationship between objective disease response and paclitaxel dose intensity in recurrent cancer of the ovary is strongly statistically significant with a two-sided p value of 0.
View Article and Find Full Text PDFThe three most active types of agents in the treatment of cancer of the ovary are platinum compounds (cisplatin or carboplatin), bifunctional alkylating agents (cyclophosphamide, melphalan, etc), and the recently developed natural product paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ). In an effort to improve long-term disease-free survival in patients with advanced disease, we have developed a three-drug regimen consisting of cisplatin, paclitaxel, and cyclophosphamide. Granulocyte-colony stimulating factor is given as bone marrow support using a flexible dosing approach.
View Article and Find Full Text PDFTaxol is a novel chemotherapeutic agent that has produced substantial responses in early clinical studies [1]. Taxol has excellent activity in a number of malignancies based on recently completed clinical trials, including a 30% response rate in platinum-refractory ovarian cancer patients [2-5]. We are currently conducting trials of dose-intense taxol with granulocyte colony stimulating factor (G-CSF) support in relapsed or refractory ovarian cancer patients.
View Article and Find Full Text PDFAs has been reported with other chemotherapeutic agents, evidence is emerging to suggest that increased taxol dose intensity is associated with improved therapeutic efficacy. Granulocyte colony-stimulating factor (G-CSF) effectively protects the bone marrow from taxol-induced neutropenia and allows for higher taxol dose administration. This report addresses the optimal use of G-CSF as a supportive agent for dose-intense taxol therapy.

Background: Paclitaxel (Taxol), a diterpene plant product that promotes tubulin polymerization, has documented activity against a number of solid tumors, including ovarian cancer and breast cancer.
Purpose: Our purpose was to conduct a phase II clinical trial investigating the response of patients with advanced recurrent ovarian carcinoma to high-dose paclitaxel combined with granulocyte colony-stimulating factor (G-CSF).
Methods: A prospective phase II clinical trial of patients with advanced-stage, recurrent ovarian cancer was undertaken.
Taxol is one of the more significant advances in cancer chemotherapy in the last 10-15 years with a 30-50% response rate in both breast and ovarian cancers. The toxicity profile of taxol is still evolving as changes in the dosing and scheduling of the drug are instituted. We herein present the first evidence of taxol-induced quantifiable, objective autonomic neuropathy in two patients, one with and one without diabetes.
