    Notes: Abstract Purpose: To determine the maximum tolerable dose (MTD), principal toxicity, and pharmacologic behaviour of Cemadotin—HCl, a novel antimitotic peptide. Patients and methods: Cemadotin—HCl (10.0 to 27.5 mg/m2/day every three weeks) was administered as a 24-hour intravenous (i.v.) continuous infusion to patients with advanced cancer. Pharmacokinetic analyses were performed during the first treatment cycle. Blood samples were taken over 48 hours and analyzed by radioimmunoassay. Results: Hypertension was the dose-limiting toxicity (DLT). This type of toxicity was observed at all dose levels, but grade 3 (CTC) was observed only at dose levels 20.0, 25.0 and 27.5 mg/m2. This effect was reversible but in three patients associated with signs of cardiac ischemia. Other significant toxic effects were neutropenia, asthenia, tumor pain and transient liver enzyme elevation. A linear pharmacokinetics was observed. The best curve fit was obtained with a two-compartment model with a terminal half-life of ≈10 hours at each dose level, a volume of distribution at steady state of ≈9 l/m2 and a total clearance of ≈0.6 l/hour/m2. Neither partial nor complete responses were observed although minor tumor regressions were seen in a patient with carcinoma of unknown primary (CUP) and in another patient with liver metastases from a colon cancer. Conclusions: Hypertension was the dose-limiting toxicity of Cemadotin—HCl administered as a continuous 24-hour infusion. The recommended dose for further evaluation of its anticancer efficacy in disease-oriented phase II studies with this schedule is 15.0 mg/m2. The nature of the principal cardio-vascular toxicity remains unclear. The observed toxicities appeared to be significant but manageable.

    Blut-Hirnschranke und Penetration von Zytostatika (1985)

    Notes: Summary The penetration of 12 commonly used anticancer agents through the blood-brain barrier (BBB) was measured in a rat model using a single-injection tissue-sampling technique. Two of the tested drugs penetrated the barrier, but only to a limited extent. Entry of the drugs into the brain tissue critically depends on molecular weight and lipophilia of the respective test compound. For drugs with a molecular weight of less than 500, BBB simply behaves like an oil/water interphase, whereas drugs with a molecular weight greater than 500 are practically excluded from transport through the BBB even if they show a favourable oil/water partition coefficient. However, permeability of cytostatics was strongly increased if short chain alkylglycerols, up to final concentrations of about 0.3 mol/l were added to the injected solution. Under these conditions the Brain-Uptake-Index (BUI) reached values up to about 50% (cyclophosphamide), depending on lipid solubility and molecular dimension of the respective test compound and the alkyl chain length of the glycerol derivative.
