    Review, Journal:  Moving Past Ganciclovir and Foscarnet: Advances in CMV Therapy. (Pubmed Central) -  Dec 23, 2020   
    Maribavir, an inhibitor of the CMV UL97 kinase, is currently in two phase 3 treatment studies...Vaccine development continues, with several promising candidates currently under study. No longer limited to DNA polymerase inhibitors, the prevention and treatment of CMV infections in the HCT recipient is a rapidly evolving field which should translate into improvements in CMV-related outcomes.

    Review, Journal, IO Biomarker:  Potential Therapeutic Approaches Against Brain Diseases Associated with Cytomegalovirus Infections. (Pubmed Central) -  Dec 1, 2020   
    Fortunately, letermovir which targets the HCMV terminase complex rather than DNA polymerase with fewer adverse reactions has been approved to treat CMV infections in humans...For the treatment of glioblastoma, vaccine therapy through targeting specific CMV antigens has improved patients' survival outcomes significantly and immunotherapy has also emerged as an alternative modality. The advanced research for developing anti-CMV agents and approaches is promising to obtain significant outcomes and expecting to have a great impact on the therapy of brain diseases associated with CMV infections.

    Moreover, CMV DNAemia at the time of PET in the 12 patients with a clinically significant CMV infection was higher in WB vs. PL (5.202 vs. 4.981 copies/ml, p = 0.1). Our real-life experience confirms that: (i) letermovir is highly effective, leading to a significant drop in CMV clinically significant infections and CMV-related complications by day + 100 and + 180 after allo-SCT; (ii) WB may be an effective alternative to PL as a source for CMV DNA monitoring, as a linear correlation of DNAemia was confirmed between WB and PL, even if the CMV DNAemia at PET initiation was comparable in the two sources.

    [VIRTUAL] Impact of Letermovir Prophylaxis on Voriconazole Exposure in Allogeneic Hematopoietic Cell Transplant Recipients () -  Nov 5, 2020 - Abstract #ASH2020ASH_4950;    
    Notably, patients receiving the 300 mg dose upfront may not require an additional dose increase to achieve a voriconazole trough within the recommended range despite the concomitant use of letermovir. Our group is collaborating with other centers to corroborate these findings, particularly in patients receiving the standard voriconazole prophylactic dose of 200 mg.

    [VIRTUAL] Healthcare Resource Utilization in Transplant Patients Who Are at a Higher-Risk to Develop Cytomegalovirus Infection during Their Primary Transplant-Related Hospitalization (Poster Hall (Virtual Meeting)) -  Nov 5, 2020 - Abstract #ASH2020ASH_1269;    
    Together, this knowledge of epidemiology and resource utilization may be used to inform preventive strategies to minimize CMVi, e.g., use of antiviral agent letermovir...Most commonly used graft-versus-host disease prophylaxis consisted of post-transplant cyclophosphamide (100%), Tacrolimus/sirolimus (83%), and cyclosporine/cellcept (78%) in Haplo, MUD, and CB-HCT recipients, respectively...CMVi during primary HCT admission was associated with significantly higher health care resource utilization; longer hospital LOS and supportive care utilization (CMV specific antiviral usage, transfusion and growth factors use). Prophylactic strategies to prevent early CMVi in alloHCT should be considered to decrease NRM and improve value based care delivery.

    Journal:  Palladium-Catalyzed Asymmetric Allylic C-H Functionalization: Mechanism, Stereo- and Regioselectivities, and Synthetic Applications. (Pubmed Central) -  Oct 4, 2020   
    In particular, the asymmetric allylic C-H alkylation of 1,4-dienes with azlactones offers highly enantioenriched α,α-disubstituted α-amino acid derivatives that are capable of serving as key building blocks for the enantioselective synthesis of lepadiformine alkaloids. In addition, a tachykinin receptor antagonist and (-)-tanikolide are also synthesized with chiral molecules generated from the corresponding allylic C-H alkylation reactions.

    Journal:  The terminase complex, a relevant target for the treatment of HCMV infection (Pubmed Central) -  Oct 3, 2020   
    A new terminase inhibitor, letermovir, recently proved effective against HCMV in phase III clinical trials. However, its mechanism of action is unclear and it has no significant activity against other herpesvirus or non-human CMV.

    Clinical, Journal:  Letermovir as Salvage Therapy for Cytomegalovirus Infection in Transplant Recipients. (Pubmed Central) -  Oct 1, 2020   
    Letermovir was well tolerated and effective in treating CMV-infections in lung transplant recipients failing on currently available antiviral agents. We demonstrate mixed efficacy in patients with refractory CMV infection suggesting that letermovir may be a useful therapeutic adjunct, potentially in combination with other antivirals.

    Review, Journal:  Antiviral Agents as Therapeutic Strategies Against Cytomegalovirus Infections. (Pubmed Central) -  Sep 30, 2020   
    Fortunately, letermovir which targets the human CMV (HCMV) terminase complex has been recently approved to treat CMV infections in humans...Additionally, adoptive T cell therapy (ACT) has been experimentally used to combate drug-resistant and recurrent CMV in patients after cell and/or organ transplantation. Developing antiviral agents is promising in this area to obtain fruitful outcomes and to have a great impact on humans for the therapy of CMV infections.

    Journal:  Validation and characterization of five distinct novel inhibitors of human cytomegalovirus. (Pubmed Central) -  Sep 26, 2020   
    Drug combination studies revealed that all five compounds were additive with ganciclovir or letermovir. Future studies will determine the potential for development of these new compounds as anti-HCMV drugs and their use as probes to study virus-host interaction.

    Journal:  DNA Encapsidation and Capsid Assembly Are Underexploited Antiviral Targets for the Treatment of Herpesviruses. (Pubmed Central) -  Sep 11, 2020   
    Acyclovir is the drug of choice for HSV encephalopathy, yet there is an estimated 6-19% mortality rate with half of the survivors experiencing moderate to severe chronic neurological deficits...Drug resistance is a concern for HCMV, HSV, and VZV since approved drugs share common mechanisms of action. Targeting DNA encapsidation or capsid assembly provide additional options for the development of non-nucleoside, small molecule anti-herpesviral drugs.
