Isavuconazole and Liposomal Amphotericin B as Successful Combination Therapy of Refractory Invasive Candidiasis in a Liver Transplant Recipient: A Case Report and Literature Review.
Invasive fungal infections in liver transplant recipients are associated with elevated morbidity and mortality and pose a challenge to the treating physicians. Despite of lacking clinical data, the use of antifungal combination therapy is often considered to improve response rates in an immunocompromised patient population. We herein report a case of refractory invasive candidiasis in a liver transplant recipient treated successfully with a combination of isavuconazole und high-dose liposomal amphotericin B. The antimycotic combination treatment was able to clear a bloodstream infection with C. glabrata and led to regression of bilomas among tolerable side effects. The use of the above-mentioned antifungal combination therapy in a liver transplant recipient has not been reported previously. This case highlights the efficacy and safety of antifungal combination therapy in immunocompromised patients with refractory invasive candidiasis.

New Perspectives on Antimicrobial Agents: Isavuconazole.
Isavuconazole is the newest of the clinically available advanced generation triazole antifungals and is active against a variety of yeasts, molds, and dimorphic fungi. Its current FDA-approved indications include the management of invasive aspergillosis as well as mucormycosis, though the latter indication is supported by limited clinical data. Isavuconazole did not achieve noninferiority to caspofungin for the treatment of invasive candidiasis and therefore lacks an FDA-approved indication for this invasive disease. Significant advantages of isavuconazole, primarily over voriconazole but in some circumstances posaconazole as well, make it an appealing option for the management of complex patients with invasive fungal infections. These potential advantages include lack of QTc interval prolongation, more predictable pharmacokinetics, a less complicated drug interaction profile, and improved tolerability, particularly when compared to voriconazole. This review discusses these topics in addition to addressing the Topics: Antifungal Agents; Candidiasis, Invasive; Caspofungin; Fungi; Humans; Invasive Fungal Infections; Nitriles; Pyridines; Triazoles; Voriconazole | 2022 |
Clinical research advances of isavuconazole in the treatment of invasive fungal diseases.
Invasive fungal diseases (IFD) are a major global public health concern. The incidence of IFD has increased the demand for antifungal agents. Isavuconazole (ISA) is a new triazole antifungal agent that has shown promising efficacy in the prophylaxis and treatment of invasive fungal diseases. The aim of this review is to summarize the recent real-world experiences of using ISA for the treatment and prevention of IFD.. We performed a comprehensive literature search of the MEDLINE, PubMed, Embase, and Cochrane databases for clinical applications of ISA in the real world. Tables and reference lists are presented for this systematic review.. IFD poses a major threat to public health and causes high mortality rates. ISA may provide a good treatment. For example, the efficacy of ISA in the treatment of invasive aspergillosis (IA) is comparable to that of voriconazole, and its efficacy in the treatment of invasive mucormycosis (IM) is similar to that of liposomal amphotericin B (L-AmB); therefore, ISA is recommended as the first-line treatment for IA and IM. ISA can also achieve good efficacy in the treatment of invasive candidiasis (IC) and can be used as an alternative to de-escalation therapy after first-line drug therapy. In addition, most studies have shown the efficacy and safety of ISA for the prophylaxis of IFD.. Taken together, ISA are expected to become a new choice for the treatment and prevention of IFD because of their good tolerability, high bioavailability, and few drug interactions.

Dosing of antifungal agents in obese people.
Obesity is a worldwide epidemic associated with multiple comorbidities that increase the risk of hospitalization. Very little pharmacokinetic data are available for antifungal agents in obesity, as this population is often excluded from drug development studies and these agents are less commonly used than other antimicrobials. Systemic antifungal therapy for invasive candidiasis continues to have a high failure rate, and dose optimization in obesity provides an opportunity for improvement. Based on currently available data, some antifungals should be dosed based on total body weight (i.e. fluconazole), while others should not be adjusted for increased body weight (i.e. posaconazole). More studies are needed to determine if and when dosing changes are needed for many of the antifungal agents. Therefore, drug therapy regimens should be individually evaluated for dose optimization due to body weight.

Isavuconazole: A New Option for the Management of Invasive Fungal Infections.
To review the pharmacology, chemistry, in vitro susceptibility, pharmacokinetics, clinical efficacy, safety, tolerability, dosage, and administration of isavuconazole, a triazole antifungal agent.. Studies and reviews were identified through an English language MEDLINE search (1978 to March 2015) and from http://www.clinicaltrials.gov, Food and Drug Administration (FDA) briefing documents, program abstracts from international symposia, and the manufacturer's Web site.. All published and unpublished trials, abstracts, in vitro and preclinical studies, and FDA briefing documents were reviewed.. Isavuconazole has activity against a number of clinically important yeasts and molds, including Candida spp, Aspergillus spp, Cryptococcus neoformans, and Trichosporon spp and variable activity against the Mucorales. Isavuconazole, available for both oral and intravenous administration, is characterized by slow elimination allowing once-daily dosing, extensive tissue distribution, and high (>99%) protein binding. The most commonly reported adverse events, which are mild and limited in nature, include nausea, diarrhea, and elevated liver function tests. Its drug interaction potential appears to be similar to other azole antifungals but less than those observed with voriconazole. Comparative trials are under way or have been recently completed for the treatment of candidemia, invasive candidiasis and aspergillosis, and rare mold infections.. Isavuconazole has a broad spectrum of activity and favorable pharmacokinetic properties, providing an advantage over other currently available broad-spectrum azole antifungals and a clinically useful alternative to voriconazole for the treatment of invasive aspergillosis. It may also prove useful for the treatment of candidemia and invasive mold infections; however, these indications await the results of clinical trials.

Isavuconazole: Pharmacology, Pharmacodynamics, and Current Clinical Experience with a New Triazole Antifungal Agent.
Coinciding with the continually increasing population of immunocompromised patients worldwide, the incidence of invasive fungal infections has grown over the past 4 decades. Unfortunately, infections caused by both yeasts such as Candida and molds such as Aspergillus or Mucorales remain associated with unacceptably high morbidity and mortality. In addition, the available antifungals with proven efficacy in the treatment of these infections remain severely limited. Although previously available second-generation triazole antifungals have significantly expanded the spectrum of the triazole antifungal class, these agents are laden with shortcomings in their safety profiles as well as formulation and pharmacokinetic challenges. Isavuconazole, administered as the prodrug isavuconazonium, is the latest second-generation triazole antifungal to receive U.S. Food and Drug Administration approval. Approved for the treatment of both invasive aspergillosis and invasive mucormycosis, and currently under investigation for the treatment of candidemia and invasive candidiasis, isavuconazole may have therapeutic advantages over its predecessors. With clinically relevant antifungal potency against a broad range of yeasts, dimorphic fungi, and molds, isavuconazole has a spectrum of activity reminiscent of the polyene amphotericin B. Moreover, clinical experience thus far has revealed isavuconazole to be associated with fewer toxicities than voriconazole, even when administered without therapeutic drug monitoring. These characteristics, in an agent available in both a highly bioavailable oral and a β-cyclodextrin-free intravenous formulation, will likely make isavuconazole a welcome addition to the triazole class of antifungals.

Evaluation of the pharmacokinetics and clinical utility of isavuconazole for treatment of invasive fungal infections.
Invasive fungal infections remain a leading cause of infectious morbidity and mortality in immunocompromised patients. There are relatively few effective antifungal agents, and currently available agents all have significant limitations. Isavuconazole is a novel second-generation triazole with broad-spectrum antifungal activity, and a favorable pharmacokinetic-pharmacodynamic profile. Isavuconazole is available as an oral and intravenous formulation. Phase III studies that are examining the efficacy of isavuconazole for invasive candidiasis and invasive aspergillosis are currently in progress.. This review provides a summary of the pharmacological characteristics of isavuconazole and the potential future use of this agent. The preclinical and clinical pharmacokinetics and pharmacodynamics are discussed. This review was constructed by searching isavuconazole, triazole, pharmacokinetics and pharmacodynamics in PubMed. References and abstracts that were not identified by this method were retrieved from the respective publications.. Isavuconazole has the potential to become an important agent for the treatment of invasive fungal infections, principally because of its relatively broad and potent in vitro antifungal activity, and its favorable pharmacokinetic profile. Further preclinical and clinical studies are required to define the clinical utility of this agent, especially for invasive candidiasis and invasive aspergillosis. Further information is required on the likely drug interactions, and in vitro susceptibility breakpoints for medically important invasive fungal pathogens. Further pharmacokinetic studies are also required in a range of patient populations to quantify the extent and sources of pharmacokinetic variability.

Newer antifungal agents.
The frequency and spectrum of fungal infections have been increasing steadily over the last several decades. The reason for this increase may be explained by the increase in the number of immunocompromised patients due to malignancies, AIDS, invasive surgical procedures and transplantation. In parallel with this increase, several therapeutic options have become available but problems such as intrinsic or acquired antifungal resistance have led researchers to develop new antifungal drugs with expanded effectiveness. Reduced toxicity, enhancement of bioavailability and counteraction of resistance are features desired by clinicians. The aim of this article is to summarize the studies involving isavuconazole, ravuconazole, albaconazole, aminocandin and some other investigational antifungal agents. Most data on the clinical use of ravuconazole, isavuconazole and albaconazole are mainly available as meeting abstracts or limited to animal studies or Phase I/II studies in humans. These new antifungal agents in development offer extended half-lives, possibly reduced drug interaction profiles and good tolerance. In addition to activity against Candida and Aspergillus spp., they have a broad spectrum of activity including activity against resistant and emerging pathogens. The real possibilities of these agents will only be fully understood after adequate randomized clinical trials.

Isavuconazole Versus Caspofungin in the Treatment of Candidemia and Other Invasive Candida Infections: The ACTIVE Trial.
Isavuconazole was compared to caspofungin followed by oral voriconazole in a Phase 3, randomized, double-blind, multinational clinical trial for the primary treatment of patients with candidemia or invasive candidiasis.. Adult patients were randomized 1:1 to isavuconazole (200 mg intravenous [IV] three-times-daily [TID] for 2 days, followed by 200 mg IV once-daily [OD]) or caspofungin (70 mg IV OD on day 1, followed by 50 mg IV OD [70 mg in patients > 80 kg]) for a maximum of 56 days. After day 10, patients could switch to oral isavuconazole (isavuconazole arm) or voriconazole (caspofungin arm). Primary efficacy endpoint was successful overall response at the end of IV therapy (EOIVT) in patients with proven infections who received ≥1 dose of study drug (modified-intent-to-treat [mITT] population). The pre-specified noninferiority margin was 15%. Secondary outcomes in the mITT population were successful overall response at 2 weeks after the end of treatment, all-cause mortality at days 14 and 56, and safety.. Of 450 patients randomized, 400 comprised the mITT population. Baseline characteristics were balanced between groups. Successful overall response at EOIVT was observed in 60.3% of patients in the isavuconazole arm and 71.1% in the caspofungin arm (adjusted difference -10.8, 95% confidence interval -19.9--1.8). The secondary endpoints, all-cause mortality, and safety were similar between arms. Median time to clearance of the bloodstream was comparable between groups.. This study did not demonstrate non-inferiority of isavuconazole to caspofungin for primary treatment of invasive candidiasis. Secondary endpoints were similar between both groups.. NCT00413218.

In vitro combination therapy with isavuconazole against Candida spp.
Combination therapy may be an alternative therapeutic approach for difficult-to-treat Candida infections with the aim of increasing efficacy of antifungal therapy. Whether isavuconazole, an extended-spectrum triazole, possesses synergistic activity in combination therapy with echinocandins or polyenes for the treatment of invasive candidiasis has not been studied. We used Bliss independence drug interaction analysis and time-kill assays to examine the in vitro interactions of isavuconazole with amphotericin B or micafungin, an echinocandin, against strains of Candida albicans, Candida parapsilosis, Candida glabrata, Candida tropicalis, and Candida krusei. The Bliss independence-based drug interactions modeling showed that the combination of isavuconazole and micafungin resulted in synergistic interactions against C. albicans, C. parapsilosis, and C. krusei. The degree of synergy ranged from 1.8% to 16.7% (mean %ΔΕ value) with the highest synergy occurring against C. albicans (⊙SYN% = 8.8%-110%). Time-kill assays showed that the isavuconazole-micafungin combination demonstrated concentration-depended synergy against C. albicans and C. parapsilosis. The combined interaction by Bliss analysis between isavuconazole and amphotericin B was indifferent for C. albicans, C. parapsilosis, and C. tropicalis while for C. glabrata was antagonistic (-2% to -6%) and C. krusei synergistic (3.4% to 7%). The combination of isavuconazole-amphotericin B by time-kill assay was antagonistic against C. krusei and C. glabrata. Collectively, our findings demonstrate that combinations of isavuconazole and micafungin are synergistic against Candida spp., while those of isavuconazole and amphotericin B are indifferent in vitro.

Determination of isavuconazole susceptibility of Aspergillus and Candida species by the EUCAST method.
Isavuconazole is a novel expanded-spectrum triazole, which has recently been approved by the FDA as an orphan drug to treat invasive aspergillosis and is currently being studied in phase III clinical trials for invasive candidiasis. The susceptibility of relatively few clinical isolates has been reported. In this study, the isavuconazole susceptibilities of 1,237 Aspergillus and 2,010 Candida geographically diverse clinical isolates were determined by EUCAST methodology at four European mycology laboratories, producing the largest multicenter data set thus far for this compound. In addition, a blinded collection of 30 cyp51A mutant Aspergillus fumigatus clinical isolates and 10 wild-type isolates was tested. From these two data sets, the following preliminary epidemiological cutoff (ECOFF) values were suggested: 2 mg/liter for Aspergillus fumigatus, Aspergillus terreus, and Aspergillus flavus; 4 mg/liter for Aspergillus niger; 0.25 mg/liter for Aspergillus nidulans; and 0.03 mg/liter for Candida albicans, Candida parapsilosis, and Candida tropicalis. Unfortunately, ECOFFs could not be determined for Candida glabrata or Candida krusei due to an unexplained interlaboratory MIC variation. For the blinded collection of A. fumigatus isolates, all MICs were ≤2 mg/liter for wild-type isolates. Differential isavuconazole MICs were observed for triazole-resistant A. fumigatus isolates with different cyp51A alterations: TR34/L98H mutants had elevated isavuconazole MICs, whereas isolates with G54 and M220 alterations had MICs in the wild-type range, suggesting that the efficacy of isavuconazole may not be affected by these alterations. This study will be an aid in interpreting isavuconazole MICs for clinical care and an important step in the future process of setting official clinical breakpoints.
