    Notes: Abstract Cyclosporin (CsA) is currently the main immunosuppressive agent used in organ transplantation with considerable improvement in graft survival. Oral CsA solution is highly lipophilic, and its bioavailability may be reduced in cystic fibrosis (CF) heart-lung transplant recipients with pancreatic, gastrointestinal, and hepatic insufficiency. The bioavailability of oral CsA solution in 7 CF transplant recipients (5 male and 2 female with a mean age of 27 years and a mean weight of 49 kg) and 3 non-CF heart-lung recipients (1 male and 2 female with a mean age of 41 years and a mean weight of 60 kg) was studied. Following intravenous CsA administration, the kinetic curves were similar with no significant difference in the volume of distribution and clearance of CsA demonstrated between the CF and non-CF groups. The mean daily dose of oral CsA in 7 CF subjects (23.3 mg·kg−1) was significantly higher than the 3 non-CF heart-lung recipients (4.8 mg·kg−1). The mean maximum blood concentration of CsA for the oral dose was 776 ng·ml−1 for the 7 CF subjects, which was comparable with the mean peak values of 789 ng·ml−1 for the 3 non-CF control subjects. Poor enteral absorption of CsA probably accounts for the significantly lower mean bioavailability in the 7 CF subjects (14.9%) compared with the 3 non-CF control subjects (39.4%). The effects on the bioavailability of oral CsA solution by pancreatic enzymes (Creon) and histamine-2 antagonist (ranitidine) were also evaluated in the 7 CF subjects. No significant difference was demonstrated.

    Notes: Summary Carboplatin (Cb) is an active drug in ovarian carcinoma that has fewer visceral side effects than cisplatin (CDDP) but higher myelotoxicity, which makes it difficult to combine at efficient doses with other myelotoxic drugs. In a preliminary study in advanced ovarian carcinoma, Rosso et al. [4] showed the maximum tolerated dose of Cb given in combination with cyclophosphamide (C) and adriamycin (A) to be 200 mg/m2. Since the efficacy of Cb may be dose-dependent, as is that of CDDP, we started a feasibility study of a CACb-300 regimen, that is, using Cb at 300 mg/m2 with lower C and A doses. Our data shows that the CACb-300 combination can safely be given in previously untreated patients for at least six 28-day cycles.
