Komatsu, Ph.D., RAC, Eric F. Donaldson, Ph.D. & Anamaris M. Colberg Poley, Ph.D. CLINICAL VIROLOGY REVIEW ADDENDUM 1. Introduction and Background The purpose of this review addendum is to document the following: Final agreed labeling for Section 12.4 Microbiology Final agreed PMRs/PMCs related to Clinical Virology 2. Final Agreed Labeling for Section 12.4 Microbiology The final agreed Microbiology section of the label (12.4 Microbiology) is shown below. Note that additional Clinical Virology-related edits such as the highlights and section 12.1 have been suggested and incorporated into other sections of the label as appropriate (reviewed in SDN 000). 12.4 Microbiology Mechanism of Action Letermovir inhibits the CMV DNA terminase complex (pUL51, pUL56, and pUL89) which is required for viral DNA processing and packaging. Biochemical characterization and electron microscopy demonstrated that letermovir affects the production of proper unit length genomes and interferes with virion maturation. Genotypic characterization of virus resistant to letermovir confirmed that letermovir targets the terminase complex. Antiviral Activity The median EC50 value of letermovir against a collection of clinical CMV isolates in a cell-culture model of infection was 2.1 nM (range = 0.7 nM to 6.1 nM, n = 74). There was no significant difference in EC50 value by CMV gB genotype (gB1=29; gB2=27; gB3=11; and gB4=3). Combination Antiviral Activity No antagonism of the antiviral activity was seen when letermovir was combined with CMV DNA polymerase inhibitors (cidofovir, foscarnet, or ganciclovir). Viral Resistance In Cell Culture CMV mutants with reduced susceptibility to letermovir have been selected in cell culture and the resistance mutations map to UL56. Resistance-associated substitutions occur between amino acid positions pUL56 231 and 369 (V231A/L, V236L/M, E237D, L241P, T244K/R, L257I, F261C/L/S, Y321C, C325F/R/Y, M329T, R369G/M/S). EC50 values for virus expressing these substitutions are 13- to 5,870- fold higher than those for the wild-type reference virus. In Clinical Studies In a Phase 2b trial evaluating letermovir or placebo in 131 HSCT recipients, DNA sequence analysis of a select region of UL56 (amino acids 231 to 369) was performed on samples obtained from 12 letermovir- treated subjects who experienced prophylaxis failure and for whom on-treatment samples were available for analysis. One subject had a letermovir resistance substitution, pUL56 V236M. In a Phase 3 trial (P001), DNA sequence analysis of the entire coding regions of UL56 and UL89 was performed on samples obtained from 28 letermovir-treated subjects who had received at least one dose of study drug and experienced prophylaxis failure and for whom samples were available for analysis. Two subjects were identified as having a letermovir-resistance substitution, pUL56 V236M or C325W. 3 Reference ID: 4177492 DIVISION OF ANTIVIRAL PRODUCTS (HFD-530) VIROLOGY REVIEW NDA: 209939 SDN: 000 Addendum DATE REVIEWED: September 22, 2017 Clinical Virology Reviewers: Takashi E.

During admission, the patient was continued on daily oral posaconazole for antifungal prophylaxis and was found to have subtherapeutic posaconazole and deficient vitamin levels, likely secondary to his gastrojejunostomy and increased gastric transit time. The oral posaconazole was altered to twice-daily dosing in an effort to increase serum drug levels and prevent IFIs. Conclusion. Patients with a history of gastric bypass are at increased risk for malabsorption of oral posaconazole and nutrients, especially following HSCT with suspected GI GVHD.

Typically, HCMV causes asymptomatic infection in the immunocompetent population, while in immunocompromised individuals or when transmitted vertically from the mother to the fetus it leads to systemic disease with severe complications and high mortality rate. Following primary infection, HCMV establishes a state of latency primarily in myeloid cells, from which it can be reactivated by various inflammatory stimuli. Several studies have shown that HCMV, despite being a DNA virus, is highly prone to genetic variability that strongly influences its replication and dissemination rates as well as cellular tropism. In this scenario, the few currently available drugs for the treatment of HCMV infections are characterized by high toxicity, poor oral bioavailability, and emerging resistance.

  • Drugs/Medications Known to Cause Diaphoresis
    Drugs/Medications Known to Cause Diaphoresis Certain prescription and non-prescription medications can cause diaphoresis (excess perspiration or sweating) as a side effect. A list of potentially sweat-inducing medications is provided below. Medications are listed alphabetically by generic name. U.S. brand names are given in parentheses, if applicable. This list is provided as a resource and a service. It is not exhaustive and is in no way meant to replace consultation with a medical professional.
