Preclinical Evaluation of the Stability, Safety and Efficacy of CD101, a Novel Echinocandin

Fungal infections pose a significant public health burden with high morbidity and mortality. CD101 is a novel echinocandin under development for the treatment and prevention of systemic Candida infections. Preclinical studies were conducted to evaluate the metabolic stability, plasma protein binding, pharmacokinetics, toxicity, and efficacy of CD101 at various dose levels. CD101 was stable to biotransformation in rat/monkey/human liver microsomes and rat/monkey/dog/human hepatocytes.

Most systemic fungal infections are caused by opportunistic fungal pathogens in immunocompromised hosts. However, invasive disease can occur in immunocompetent individuals if the exposure dose is high or with primary (dimorphic) fungal pathogens (causes of endemic mycoses include Blastomyces, Coccidioides, Histoplasma, Paracoccidioides and Talaromyces spp.). Systemic fungal infections usually originate either in the lungs (Aspergillus, Cryptococcus, Mucorales spp., as a result of inhalation) or from endogenous flora (Candida spp.

Despite increasing rates of invasive fungal infections being reported globally, only a single antifungal drug has been approved during the last decade. Resistance, toxicity, drug interactions and restricted routes of administration remain unresolved issues. This review focuses on new antifungal compounds which are currently in various clinical phases of development. We discuss two azoles with a tetrazole moiety that allows selective activity against the fungal CYP: VT-1161 for Candida infections and VT-1129 for cryptococcal meningoencephalitis.

Abstract BackgroundProspective studies to determine associated risk factors and related outcomes for pulmonary fungal infection (PFI) after pediatric lung transplant (PLT) are lacking. MethodsNIH‐sponsored Clinical Trials in Organ Transplantation in Children enrolled PLT candidates, collecting data prospectively for 2 years post‐transplant. Demographics, signs/symptoms, radiology, pathology and microbiology were collected. Analyses evaluated for PFI‐related risks and outcomes. ResultsIn 59 PLT, pre‐transplant fungal colonization occurred in 6 donors and 15 recipients. Cystic fibrosis (CF) was associated with pre‐...

C Agrawal, V Sood, A Kumar, V RaghavanIndian Journal of Nephrology 2017 27(5):392-394 Invasive fungal infections (IFIs) are a significant cause of morbidity in solid organ transplant (SOT) recipients. Common causes among them are Aspergillus, Candida, and Cryptococcus. Antifungal prophylaxis has led to decrease in overall incidence of IFI; however, there is very little decline in the incidence of Cryptococcal infections of SOT recipients because effective prophylaxis is not available against this infectious agent. Spectrum of manifestation of Cryptococcal infection varies in immunocompetent and immunocompromised host with...

Critically ill patients and patients with haematological cancer are HIV-negative populations at high risk of invasive fungal infections. In intensive-care units, candidaemia and intra-abdominal candidiasis predominate, but aspergillosis has emerged as a lethal, under-recognised cause of pneumonia. In patients with haematological malignancies or who have undergone stem-cell transplantations, pulmonary disease due to aspergillus and other mould diseases predominate. In this Series paper, we provide an update on risk assessment, new diagnostic strategies, and therapeutic approaches.

Conclusion The findings of this descriptive cross-sectional study clearly indicate, in wards of the hospital that used wet cooling systems, there was considerable fungal contamination, particularly Aspergillus contamination. These results highlight a clear need for greater attention to the use of non-aqueous or closed circulation cooling systems, especially where susceptible patients receive medical care.

Summary Environmental conditions for swimming facilities may support fungal growth and also may represent a biological risk for users. However, since previously published studies both cleaning procedures and sanitary regulations are likely to have been improved. The aim of the study was to examine whether attendance to public swimming pools was still a risk factor for fungal infection of the skin in Poland. We investigated the occurrence of mycotic species, in a sample from Polish swimming pools. Detection and identification of isolated species were achieved by cultural and morphological methods. Study revealed high incide...

This study verified whether the water employed in the dental units of two dental clinics at the University of Franca was contaminated with fungi. This study also evaluated the ability of the detected fungi to form biofilms. The high-revving engine contained the largest average amount of fungi, 14.93 ± 18.18 CFU/mL. The main fungal species verified in this equipment belonged to the genera Aspergillus spp., Fusarium spp., Candida spp., and Rhodotorula spp. Among the isolated filamentous fungi, only one fungus of the genus Fusarium spp. did not form biofilms. As for yeasts, all the Candida spp. isolates grew as ...
