Letermovir reduces the risk of CMV reactivation after allogeneic stem cell transplantation (A5) - Sep 20, 2021 - Abstract #DGHO2021DGHO_416; Although ganciclovir and valganciclovir are well known prophylaxis for CMV reactivation in solid-organ transplantation, the use of these drugs induces unacceptable side effects like myelosuppression in stem cell recipients...Letermovir was applied at a dose of 480 mg once a day or 240 mg once a day if cyclosporine was used as an initial immunosuppressive drug... The use of letermovir prophylaxis is associated with a significant lower risk of CMV reactivation after allogeneic stem cell transplantation.

[VIRTUAL] The significant drug-drug interaction between tacrolimus and letermovir in allogeneic hematopoietic stem cell transplantation recipients. (CHANNEL B) - Sep 12, 2021 - Abstract #ICBMT2021ICBMT_303; LET is classified as a weak-moderate CYP3A4 inhibitor and the reduction of LET dosage to half is recommended upon coadministration with cyclosporine...All patients received methotrexate at day1, 3, and 6 in combination with TAC for the prophylaxis of GVHD...Setting an appropriate TAC initial dosage can relieve the patient’s distress by reducing the frequency of blood sampling, while avoiding the complication from high TAC blood concentration such as thrombotic microangiopathy. Further studies in larger cohort are warranted.

Pseudomelanosis Duodeni: A Rare and Incidental Endoscopic Finding (Shoreline Exhibit Hall) - Sep 8, 2021 - Abstract #ACG2021ACG_613; His home medications included hydralazine, metoprolol, doxazosin, famciclovir, letermovir, atovaquone, posaconazole, prednisone, montelukast, and famotidine...His symptoms resolved after several days, and he was discharged on oral levofloxacin and vancomycin...Upper endoscopy demonstrates diffuse speckled dark pigmentation throughout the duodenal bulb (A). Histological examination of duodenal biopsies reveals pigment deposition within the lamina propria (B, hematoxylin and eosin stain) that stains negatively for iron (C, Prussian blue stain).

Journal: Letermovir for the compassionate therapeutic use of cytomegalovirus infection. (Pubmed Central) - Jul 28, 2021 This study confirms efficacy and safety of LET for prophylaxis of CS-CMVi after alloHCT in a real-world setting, resulting in a significant patient benefit by reducing hospitalization needs and exposure to potentially toxic antiviral drugs for treatment of CMV reactivation. Letermovir may be an effective and well tolerated option in the compassionate treatment of CMV infections, although recurrence of CMV and emergence of resistance may be issues.

Review, Journal: CMV Infection in Hematopoietic Stem Cell Transplantation: Prevention and Treatment Strategies. (Pubmed Central) - Jul 27, 2021 The approval of the novel anti-CMV drug letermovir in 2017 has led to an increase in the use of antiviral prophylaxis as a preferred approach for prevention in many centers...Of the different CMV vaccine trials, PepVax has shown promising results in a phase 1 trial...Maribavir and adoptive T cell therapy are promising new therapies for treatment of CMV infections. CMV vaccine trials for prevention are also under way.

Clinical, Journal, Real-world evidence: Efficacy of prophylactic letermovir for cytomegalovirus reactivation in hematopoietic cell transplantation: a multicenter real-world data. (Pubmed Central) - Jul 10, 2021 By comparing 114 patients who received LMV prophylaxis for a median 92 days to 571 patients without prophylaxis, we observed that prophylactic LMV could significantly (1) reduce the 180-day cumulative incidence of csCMV infection (44.7 vs. 72.4%, p < 0.001), (2) delay the median time until initiation of CMV antigenemia-guided preemptive therapy (90 vs. 36 days, p < 0.001), (3) shorten the duration of anti-CMV preemptive treatment (21 vs. 25 days, p = 0.006), and (4) improve the overall survival rate at 180 days after transplant (80.4 vs. 73.0%, p = 0.033) with a trend of lower non-relapse mortality (8.9 vs. 14.9%, p = 0.052). Our findings demonstrate that prophylactic LMV treatment is highly effective in preventing the development of csCMV infection and ultimately reduces transplant-related mortality.
