Background. Invasive aspergillosis (IA) is an important cause of morbidity and mortality among immunocompromised patients. Echinocandins are novel antifungal molecules with in vitro and in vivo ...activity against Aspergillus species. Methods. We investigated the efficacy and safety of caspofungin in the treatment of IA. Ninety patients with IA who were refractory to or intolerant of amphotericin B, lipid formulations of amphotericin B, or triazoles were enrolled to receive caspofungin. Results. Efficacy was assessed for 83 patients who had infection consistent with definitions of IA and who received ⩾1 dose of study drug. Common underlying conditions included hematologic malignancy (48% of patients), allogeneic blood and marrow transplantation (25% of patients), and solid-organ transplantation (11% of patients). Seventy-one patients (86%) were refractory to and 12 patients (14%) were intolerant of previous therapy. A favorable response to caspofungin therapy was observed in 37 (45%) of 83 patients, including 32 (50%) of 64 with pulmonary aspergillosis and 3 (23%) of 13 with disseminated aspergillosis. Two patients discontinued caspofungin therapy because of drug-related adverse events. Drug-related nephrotoxicity and hepatotoxicity occurred infrequently. Conclusion. Caspofungin demonstrated usefulness in the salvage treatment of IA.

DTaP5-IPV-Hib-HepB is a fully liquid investigational hexavalent vaccine directed against 6 diseases.
This multicenter, open-label, comparator-controlled, phase III study randomly assigned healthy ...infants 2-to-1 as follows: group 1 received DTaP5-IPV-Hib-HepB, PCV13, and RV5 at 2, 4, and 6 months of age followed by DTaP5, Hib-OMP, and PCV13 at 15 months of age; group 2 received DTaP5-IPV/Hib, PCV13, and RV5 at 2, 4, and 6 months of age, with HepB at 2 and 6 months of age, followed by DTaP5, Hib-TT, and PCV13 at 15 months of age.
Overall, 981 participants were vaccinated in group 1 and 484 in group 2. Immune responses in group 1 to all antigens contained in DTaP5-IPV-Hib-HepB 1 month after dose 3 and for concomitant rotavirus vaccine were noninferior to those in group 2, with the exception of antipertussis filamentous hemagglutinin (FHA) geometric mean concentrations (GMCs). Vaccine response rates for FHA were noninferior to control. After the toddler dose, group 1 immune responses were noninferior to group 2 for all pertussis antigens. Solicited adverse event rates after any dose were similar in both groups, with the exceptions of increased injection-site erythema, increased fever, and decreased appetite in group 1. Fever was not associated with hospitalization or seizures.
The safety and immunogenicity of DTaP5-IPV-Hib-HepB are comparable with the analogous licensed component vaccines. Decreased FHA GMCs and increased injection-site reactions and fever are unlikely to be clinically significant. DTaP5-IPV-Hib-HepB provides a new combination vaccine option aligned with the recommended US infant immunization schedule.
We evaluated the safety, tolerability, and efficacy of caspofungin in pediatric patients with invasive aspergillosis, invasive candidiasis, or esophageal candidiasis.
This was a multicenter, ...prospective, open-label study in children 3 months to 17 years of age with proven or probable invasive aspergillosis, proven invasive candidiasis, or proven esophageal candidiasis. All of the patients received caspofungin 70 mg/m(2) on day 1, followed by 50 mg/m(2) per day (maximum: 70 mg/day), as primary or salvage monotherapy. Favorable response was defined as complete resolution of clinical findings and microbiologic (or radiographic/endoscopic) eradication (complete response) or significant improvement in these parameters (partial response). Efficacy was assessed at the end of caspofungin therapy in patients with a confirmed diagnosis who received >/=1 dose of caspofungin. The primary safety evaluation was the proportion of patients with clinical or laboratory drug-related adverse events.
Of the 49 patients enrolled, 3 were <2 years of age, 30 were 2 to 11 years of age, and 16 were 12 to 17 years of age. Forty-eight patients had confirmed disease: invasive aspergillosis (10), invasive candidiasis (37), and esophageal candidiasis (1). Eight of 10 patients with invasive aspergillosis had pulmonary involvement; 34 of 37 patients with invasive candidiasis had candidemia. Caspofungin was given for 2 to 87 days. Success at end of therapy was achieved in 5 of 10 patients with invasive aspergillosis, 30 of 37 with invasive candidiasis, and 1 of 1 with esophageal candidiasis. One patient (invasive candidiasis) relapsed during the 28-day follow-up period. Drug-related clinical or laboratory adverse events occurred in 27% and 35% of patients, respectively. There were no serious drug-related adverse events or discontinuations of caspofungin because of toxicity.
Caspofungin was generally well tolerated in pediatric patients aged 6 months through 17 years. Efficacy outcomes in patients with invasive aspergillosis or invasive candidiasis were consistent with previous adult studies in these indications.
Abstract Safety experience is available from 32 completed clinical studies (17 Phase I and 15 Phase II–III) of caspofungin (CAS) conducted between 1995 and 2010 in adult and paediatric patients. ...Clinical and laboratory adverse events (AEs) were collected from all enrolled subjects and patients. Investigators identified the seriousness, causality and result of all AEs noted during study therapy and for up to 28 days post therapy. Up to 31 December 2010, full safety data are available from 1951 individuals who have received at least one dose of CAS in Phase I–III clinical studies, including 171 paediatric patients, 394 volunteer adult subjects and 1386 adult patients (276 with oropharyngeal/oesophageal candidiasis, 366 with invasive candidiasis, 180 with invasive aspergillosis and 564 with persistent fever and neutropenia). CAS was administered for up to 196 days at daily doses ranging from 5 mg to 210 mg. Overall, 41.8% of CAS recipients had an AE that was classified as drug-related. The most frequently reported drug-related AEs were fever (9.3%), chills (5.2%), increased alanine aminotransferase (6.5%), increased aspartate aminotransferase (6.0%) and increased alkaline phosphatase (5.2%). Serious AEs were reported in 27.3% of CAS recipients overall but were attributed to CAS in only 0.8%, and discontinuation of CAS due to a drug-related AE was infrequent (2.7%). Dose-related CAS toxicity was not observed. In conclusion, CAS has demonstrated a favourable safety profile in 1951 adult and paediatric patients enrolled in clinical trials.

We analyzed the caspofungin safety experience in 5 clinical registration studies in 171 pediatric patients, 1 week to 17 years of age. Caspofungin was administered for 1 to 87 (mean 12.1) days. The ...most common drug-related adverse events were fever, increased AST, increased ALT, and rash; few events were serious or required treatment discontinuation. Caspofungin was well tolerated in this pediatric population.
Eight hundred and twelve children, 12 months to 3.5 years of age, were enrolled in two clinical studies to evaluate the safety and immunogenicity of a live, attenuated combination vaccine for ...measles, mumps, rubella, and varicella (MMRV). Children were enrolled in one of two randomized, multicenter studies, involving administration of (1) MMRV and placebo vs. measles, mumps, and rubella vaccine (M-M-RII) and varicella-zoster virus vaccine (VARIVAX), given at separate anatomic sites at the same office visit; or (2) MMRV, DTaP (diphtheria, tetanus, and acellular pertussis vaccine) and OPV (oral polio vaccine) vs. M-M-RII, DTaP, and OPV, with VARIVAX given 6 weeks later. All vaccine regimens were generally well tolerated. More than 95% of vaccinees seroconverted for measles, mumps, rubella, and varicella, regardless of the vaccine or regimen used. In each study, the level of antibody titer to varicella virus was significantly lower in vaccinees receiving MMRV than in those who received VARIVAX in a separate syringe.

There has been minimal clinical experience with the use of the Aspergillus galactomannan enzyme-linked immunosorbent assay (ELISA) for patients receiving echinocandin therapy. We reviewed the ...experience with the galactomannan ELISA for 17 patients in a study of caspofungin treatment for invasive aspergillosis. The rate of successful outcomes for these patients was similar to that overall for participants in the study. Trends in antigenemia levels correlated with clinical and radiographic findings.

To approximate the effect of prolonged storage on safety and immunogenicity, healthy children were given a single dose of the currently marketed live attenuated varicella vaccine (3625 pfu) or of a ...partially heat-inactivated vaccine (1125 or 439 pfu), The 3 doses had similar antigen content (attenuated plus inactive virus particles). The vaccine was well tolerated. No significant differences in adverse reactions were observed. Although the seroconversion rates were excellent at each dose (⩾98%), the higher doses resulted in significantly greater geometric mean antibody titers at 6 weeks (10.5 and 10.6 ELISA U/mL) compared with the 439 pfu dose (5.7 ELISA U/mL), P ⩽ .01. One year after immunization, differences in antibodies were similar to the 6-week postimmunization results. Results indicate that until the date of expiry, the vaccine's immunogenicity will be preserved and there will be no clinically important changes in type or frequency of adverse events.
