Introduction Febrile neutropenia (FN) is a dreaded complication of cancer chemotherapy and frequently associated with respiratory infections. Flexible bronchoscopy (FB) serves as a useful diagnostic tool in this regard. Objective To determine the diagnostic yield, safety and clinical implications of
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
OBJECTIVE
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
OBJECTIVE
To determine the safety and tolerability of olaparib with cisplatin and gemcitabine, establish the maximum tolerated dose (MTD), and evaluate the pharmacodynamic and pharmacokinetic profile of the combination.
METHODS
We conducted a phase I study of olaparib with cisplatin and gemcitabine
Treatment failure from drug resistance is the primary reason for relapse in acute lymphoblastic leukemia. Improving outcomes by targeting mechanisms of drug resistance is a potential solution.We report results investigating the epigenetic modulators In previous anecdotal reports, treatment with granulocyte colony-stimulating factor has been associated with pulmonary toxicity. In 35 consecutive admissions for chemotherapy-induced febrile neutropenia, transient hypoxia occurred in 12. 10 of the 12 followed treatment with filgrastim to induce
Biosimilar products of filgrastim have become available for improved sustainability of cancer care; however, the real-world safety profile remains unknown. The purpose of this study was to clarify the adverse events associated with filgrastim originator and its biosimilar using the Japanese Adverse
OBJECTIVE
Tumor hypoxia confers chemotherapy resistance. Tirapazamine is a cytotoxin that selectively targets hypoxic cells and has supra-additive toxicity with platinums and taxanes in preclinical studies. We conducted a Phase I study of tirapazamine, carboplatin, and paclitaxel and assessed
High-risk acute promyelocytic leukemia (APL) remains a therapeutic challenge, with higher associated rates of early mortality and relapse than standard-risk APL. All-trans retinoic acid (ATRA) plus arsenic trioxide (ATO) is a well-established treatment for patients with standard-risk APL, but it is
OBJECTIVE
The primary goal was to identify the maximum tolerable dose (MTD) of thoracic radiation therapy (TRT) that can be given with chemotherapy and amifostine for patients with limited-stage small-cell lung cancer (LSCLC).
METHODS
Treatment began with two cycles of topotecan (1 mg/m(2)) Days 1
OBJECTIVE
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
OBJECTIVE
A SWOG pilot study (S0004) showed that tirapazamine (TPZ) when combined with concurrent chemoradiotherapy yielded a promising median survival of 22 months in limited-stage small-cell lung cancer (LSCLC). We report results of the phase II study designed to confirm this result.
METHODS
The
OBJECTIVE
Tumor hypoxia confers chemotherapy resistance. Tirapazamine is a cytotoxin that selectively targets hypoxic cells. We conducted a phase III clinical trial to determine whether the addition of tirapazamine to paclitaxel and carboplatin offered a survival advantage when used in the treatment
BACKGROUND
3-Aminopyridine-2-carboxaldehyde thiosemicarbazone (3-AP) is a novel small-molecule ribonucleotide reductase inhibitor. This study was designed to estimate the maximum tolerated dose (MTD) and oral bioavailability of 3-AP in patients with advanced-stage solid tumors.
METHODS
Twenty
OBJECTIVE
To determine the maximum-tolerated dose of tirapazamine when combined with cisplatin and radiation in patients with T3/4 and/or N2/3 squamous cell carcinoma of the head and neck.
METHODS
The starting schedule was conventionally fractionated radiotherapy (70 Gy in 7 weeks) with concomitant
