Abstract
Purpose Antifungal prophylaxis with posaconazole has demonstrated a reduction in the risk of death due to Invasive fungal infections (IFI)in patients with acute myeloid leukemia (AML) during induction therapy. However, various factors affect the plasma levels of posaconazole and can potentially limit its efficacy. Therapeutic drug monitoring (TDM) can help optimize the dose, but literature is scant from centers with a high IFI burden. This study aimed to evaluate the proportion of de-novo AML patients on induction who could achieve the target level of 700ng/mL with posaconazole prophylaxis,factors that can influence the plasma levels, and the impact of plasma posaconazole levels on incidence of IFI. Methods Patients with AML on induction therapy with no baseline IFI were enrolled at our tertiary cancer center which has high prevalence of IFI. These patients received posaconazole suspension as prophylaxis. Daily plasma levels were measured from Day 4 till Day 12 of posaconazole prophylaxis. All patients were monitored for the development of IFI. The data on adverse events, concomitant drugs, mucositis, vomiting, and diarrhea were recorded. Results A total of 411 samples from fifty patients were collected. Only 177 out of 411 samples had levels > 700 ng/mL. The median trough level was 610 ng/mL (range30-3000 ng/mL). The median time to achieve target trough concentration was four days (range 4-12 days) from the start of induction.Thirty-eight (76%) patients achieved target plasma levels by day 12 of induction.The median plasma level on day 12 was 690 ng/mL (range,30-1270) in patients who achieved target levels as compared to 340 (50-560) ng/mL in those who did not. Twenty-six (52%) patients had IFI in our study, and the median time to develop breakthrough IFI was 14 days (range 4-24 days). Median and range of plasma levels were 690 ng/ml (30-2410; n = 22) in those who developed IFI, while 590 ng/mL (50-2300 n = 24) in those who did not. The odds of developing IFI in patients who did not achieve the threshold trough concentration of 700 ng/mL was 7.14 (95% CI; 1.35-37.75, p = 0.0206). Occurrence of vomiting (p = 0.02), diarrhea (p = 0.0008), mucositis (p = 0.003) had adverse impact on achievement of target plasma posaconazole levels. Conclusion A significant proportion of patients receiving posaconazole prophylaxis fail to achieve target plasma levels which can result in high risk of development of IFI. Occurrence of diarrhea, vomiting and mucositis can adversely affect the achievement target plasma levels.

Deciphering the Relationship Between the Trough Concentration of Posaconazole and Its Efficacy and Safety in Chinese Patients With Hematological Disorders. Front Pharmacol 2020; 11:575463. [PMID: 33154724 PMCID: PMC7586309 DOI: 10.3389/fphar.2020.575463] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2020] [Accepted: 09/15/2020] [Indexed: 01/24/2023] Open
Abstract
Posaconazole (PCZ) is effective in preventing and salvage treatment invasive fungal infections in patients with hematologic disorders. However, PCZ displays highly variable individual pharmacokinetics affecting its efficacy and safety. To investigate the correlation between PCZ concentration and efficacy and safety, the following key influencing factors were explored. A total of 285 trough plasma concentrations (Cmin) of 81 Chinese patients receiving PCZ oral suspension for prophylaxis or treatment of invasive fungal infections were collected in this study. The relationships between Cmin values and clinical response and hepatotoxicity were investigated as well as the incidence of clinical response under different Cmin values of PCZ with a logistic regression model. The concentration of PCZ showed remarkable differences among patients with haematologic disorders. PCZ Cmin values of 0.76 and 1.0 µg/mL were both associated with an over 80% probability of successful response to prophylaxis and treatment of fungal infections, respectively. No association between Cmin values and hepatotoxicity was noted (P > 0.05). Gender, albumin, and co-administration of proton pump inhibitor (PPI) were identified as independent factors influencing PCZ Cmin by multiple linear regression analysis. Furthermore, patients’ C-reactive protein (CRP), albumin, and co-administration of PPI exhibited significant effects on the therapeutic window of patients receiving PCZ for prophylaxis. The plasma concentration is closely associated with therapeutic efficacy of PCZ. It is necessary to adjust the dosing regimens based on PCZ Cmin to obtain an optimal therapeutic response.

Abstract
Posaconazole prophylaxis is recommended for patients with acute myeloid leukaemia during induction chemotherapy. Although a tablet formulation with better oral bioavailability is available, some patients have to rely on the oral suspension in clinical routine. Therefore, effectiveness of posaconazole oral suspension under real-life clinical conditions and impact of patient education about the correct intake on its plasma concentrations were assessed in this study. Altogether 96 patients receiving 160 cycles of induction chemotherapy were retrospectively (40 patients) and prospectively (56 patients) analysed. Patients were assigned into two groups for each chemotherapy cycle according to the application of antifungal prophylaxis (A: posaconazole oral suspension, 200 mg three times a day ≥7 days; B: intake <7 days, fluconazole or no prophylaxis). Antifungal prophylaxis and therapy were analysed for each cycle. Additionally, plasma concentrations were determined from prospectively included subjects of group A who were intensively educated to perform a correct drug intake. Systemic antifungal therapy was statistically started less often in group A (26% vs 53%; P = 0.002). Posaconazole prophylaxis was associated with a lower risk of proven invasive fungal infection (P = 0.003). Median plasma concentration apparently increased between the first and second time of determination effected by an initial intensive on-site patient education. The clinical effectiveness of posaconazole oral suspension was confirmed. A detailed patient education at the beginning of the treatment with posaconazole oral suspensions seems to be of primary importance for efficient plasma concentrations.

Utility of posaconazole therapeutic drug monitoring and assessment of plasma concentration threshold for effective prophylaxis of invasive fungal infections: a meta-analysis with trial sequential analysis.

[PMID: 29609553 PMCID: PMC5879730 DOI: 10.1186/s12879-018-3055-3] [Citation(s) in RCA: 26] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2017] [Accepted: 03/21/2018] [Indexed: 12/13/2022] Open
Abstract
Background Posaconazole therapeutic drug monitoring (TDM) is increasingly used in clinical practice. However, the utility of posaconazole TDM and the target of posaconazole plasma concentration for clinical successful prophylaxis remain uncertain and controversial. The aim of this study was to evaluate posaconazole exposure-response relationship and determine an optimum posaconazole concentration for prophylaxis against invasive fungal infections (IFIs). Methods Bibliographic databases were searched (from inception to September 2017) to select studies including the clinical outcomes below and above concentration cut-off value of 0.5 mg/L and 0.7 mg/L. The reliability of the results were evaluated with trial sequential analysis (TSA). Results Twenty-eight studies with 1930 patients included were analyzed. The results of our pooled analysis demonstrated that patients with posaconazole plasma concentrations over 0.5 mg/L were twice more likely to achieve successful responses compared with those with lower concentrations (odds ratio, OR = 1.98, 95% confidence interval, CI 1.09–3.58, P = 0.02) while the threshold, 0.7 mg/L showed no significant difference (OR = 1.84, 95% CI 0.94–3.63, P = 0.08). The TSA results showed that there was sufficient information to support these findings. Conclusions An optimal posaconazole concentration target of 0.5 mg/L is suggested to ensure the clinical prophylactic efficacy and may help reduce the dosage and dose-dependent toxicity comparing with the target of 0.7 mg/L.

Abstract
OBJECTIVE To study the efficacy and safety of micafungin for prophylaxis of invasive fungal infections in patients undergoing induction chemotherapy for acute myeloid leukemia. PATIENTS AND METHODS A prospective observational single-center study of 41 patients from the hematology department between May 2012 and April 2015. Micafungin was administered once daily from the first day of induction chemotherapy to the end of the neutropenic phase. RESULTS Neither Candida nor Aspergillus infection was documented in our 41 patients from the first day of micafungin infusion to the end of the neutropenic phase. Patients were followed for three months after discontinuation of micafungin and none of them contracted an invasive fungal infection. Only one patient presented with grade III-IV hepatic and ionic toxicities. CONCLUSION Micafungin is associated with a good safety profile and is an interesting option for preventing invasive fungal infections in the high-risk population of patients presenting with hematological disorders.
