Amonafide (benzisoquinolinedione, NSC 308847) is a new synthetic imide antineoplastic agent with DNA intercalative properties that has been evaluated in a phase I clinical trial. The drug was administered as a single intravenous (IV) infusion over 30 to 120 minutes repeated every 28 days. Ninety-five courses of therapy at doses ranging from 18 to 1,104 mg/m2 were administered to 38 patients with refractory solid tumors. Granulocytopenia was dose limiting. Leukopenia was seen in 13 of 31 courses at doses of 690 mg/m2 or greater. Life-threatening granulocytopenia (less than or equal to 250 microliters) was noted in 1/6 patients treated at 800 mg/m2, 1/8 patients treated at 918 mg/m2, and 2/5 patients treated at 1,104 mg/m2. No definite relationship between myelotoxicity and prior treatment status was noted. Rate-of-infusion dependent, nonhematologic toxicities included diaphoresis, flushing, dizziness, and tinnitus, all of which were ameliorated by increasing the duration of drug infusion to 120 minutes. In addition, nausea and vomiting (grades 1 and 2) were seen in 29/56 courses at doses greater than or equal to 519 mg/m2, but were easily controlled by phenothiazine antiemetics. Amonafide plasma and urine concentrations were determined by high-pressure liquid chromatography (HPLC). Plasma concentrations declined biexponetially with a terminal harmonic mean terminal half-life (t 1/2) of 5.5 h. The mean apparent volume of distribution at steady-state and total body clearance were 532 L/m2 and 84 L/h/m2, respectively. Less than 5% of the total dose of amonafide was excreted unchanged in the urine. Antitumor activity has been noted in one patient with non-small-cell lung cancer (one complete response exceeding 29 months duration) and in one patient with prostatic cancer (complete pain relief and improvement in bone scan for 9 months). The recommended dose for phase II trials with this schedule of amonafide is 918 mg/m2 with dose escalation to amonafide is 918 mg/m2 with dose escalation to myelotoxicity.

Taxol inhibits cell division by promoting the assembly and stabilization of microtubules. This report describes the results of a phase I trial of taxol administered as a short iv infusion daily for 5 days every 4 weeks. Sixteen patients with refractory malignancy received 21 courses of taxol at five doses between 5 and 40 mg/m2/day X 5. The first nine patients received taxol as a 60-minute infusion. Two patients experienced anaphylactoid reactions, one at the 5-mg/m2/day and the second at the 15-mg/m2/day X 5 dose levels. These reactions were characterized by facial flushing, tachypnea, and hypotension within several minutes of drug administration. These anaphylactoid reactions occurred on the first day of treatment in the first patient and on the first day of the second course in the second patient. These reactions may be related to the rapid administration of the polyoxyethylated castor oil (Cremophor EL) vehicle in which taxol is formulated. No anaphylactoid reactions were observed in the seven patients who received taxol as a 6-hour infusion with antihistamine and prednisone premedication. Dose-related myelosuppression was seen; leukopenia (wbc count less than 1000/mm3) and granulocytopenia (granulocytes less than or equal to 200/mm3) occurred on Days 8 and 9 in two of two patients treated at the 40 mg/m2/day X 5 level. Thrombocytopenia was mild, with a platelet nadir of 87,000-95,000/mm3 at the highest dose level. Premedication with glucocorticoids and antihistamines coupled with a prolonged 6-hour infusion permitted taxol to be administered at 30 mg/m2/day X 5 safely without immediate life-threatening reactions.

Spontaneous reporting system (SRS) datais currently an important source of monitoring and finding ADRs signals throughout the world. This method can promptly and effectively discover ADR signals, thus preventing and avoiding ADRs effectively. Parenterally administered Shenmai has the functions of benefiting vital energy, nourishing Yin and generating body fluids, and activating the pulse. Clinically it is used in various diseases including shock, coronary heart disease, viral myocarditis, chronic pulmonary heart disease, and granulocytopenia. The large, national SRS database of ADRs needs effective evaluation methods. We report on the use of Bayesian confidence propagation neural network method (BCPNN) and proportional reporting ration (PRR) with propensity score to control for confounding variables. Early warning signs of an ADR are, a feeling of suffocation (difficulty exhaling), anaphylactoid reactions and flushing. Furthermore, relevant relationships between the different factors is analysed by association rules (AR). It is found that there is a close relationship between past history of ADRs, a family history of ADRs and itching.
