As applicable, a parent/both parents or legally authorized representative (LAR) must provide signature of informed consent and there must be documentation of assent by the participant before completing any study-related procedures.
  2. The participant must be a recipient of hematopoietic stem cell or solid organ transplant.
  3. The participant must have a documented CMV infection in whole blood or plasma, with a screening value of greater than or equal to (>=) 2730 international units per milliliter (IU/mL) in whole blood or >= 910 IU/mL in plasma in 2 consecutive assessments, separated by at least 1 day, as determined by local or central specialty laboratory quantitative polymerase chain reaction (qPCR) or comparable quantitative CMV DNA results.

The same laboratory and same sample type (whole blood or plasma) must be used for these assessments.
  4. The participant must have a current CMV infection that is refractory to the most recently administered of the four anti-CMV treatment agents. Refractory is defined as documented failure to achieve greater than (>) 1 log10 (common logarithm to base 10) decrease in CMV DNA level in whole blood or plasma after a 14 day or longer treatment period with intravenous (IV) ganciclovir/oral valganciclovir, IV foscarnet, or IV cidofovir.

  5. The Investigator must be willing to treat the participant with at least one of the available anti-CMV drugs (ganciclovir, valganciclovir, foscarnet, or cidofovir). Note: Combination therapy with foscarnet and cidofovir is not permitted in the investigator-assigned anti-CMV treatment (IAT) arm due to the potential for serious nephrotoxicity.
  6. The participant must be >= 12 years of age at the time of consent.
  7. The participant must weigh >= 35 kilogram (kg).
  8. The participant must have all of the following results as part of screening laboratory assessments (results from either the central laboratory or a local laboratory can be used for qualification):

Additional urine pregnancy tests may be done per institutional requirements. Sexually active females of child bearing potential must agree to comply with any applicable contraceptive requirements of the protocol. If male, must agree to use an acceptable method of birth control, as defined in the protocol, during the study treatment administration period and for 90 days afterward if treated with maribavir, ganciclovir, valganciclovir, or cidofovir and for 180 days afterward if treated with foscarnet.

  2. Require ganciclovir, valganciclovir, foscarnet, or cidofovir administration for conditions other than CMV when study treatment is initiated (example: herpes simplex virus (HSV) coinfection requiring use of any of these agents after the randomization) or would need a coadministration with maribavir for CMV infection. NOTE: A participant who is not continuing with the same anti-CMV drug(s) (ganciclovir, valganciclovir or foscarnet) for the study treatment (if randomized to the investigator assigned anti-CMV treatment arm), must discontinue their use before the first dose of study drug. If participant is currently being treated with cidofovir and is assigned another anti-CMV therapy by the investigator, the participant must discontinue its use at least 14 days prior to randomization at Visit 2/Day 0 and the first dose of study treatment.
