A Phase 3 Trial to Compare IV BCV Versus IV CDV for Treatment of Adenovirus Infection After Allo-HCT
(ENOVIA)
What this study is about
This randomly assigned, where both patients and doctors know the treatment given, parallel group, two-treatment group$1, multi-center assessment will compare IV BCV with IV CDV in adult and pediatric allogeneic HCT recipients with AdV viremia.
View original scientific description
This randomized, open-label, parallel group, two-arm, multi-center assessment will compare IV BCV with IV CDV in adult and pediatric allogeneic HCT recipients with AdV viremia. A virologic response-driven approach to duration of treatment will be evaluated, in which randomized subjects are treated with either BCV or CDV until AdV viremia is confirmed as undetectable or until a maximum of 12 weeks of therapy, whichever occurs first. All subjects will be followed for a total of 24 weeks post-randomization, regardless of treatment assignment. Subjects will be assessed on a weekly basis through the end of treatment visit (EOT). Additional assessments will be performed at the test of cure (TOC) visit, which is 4 weeks after the last dose of study drug and at Weeks 12 and 24 post W1D1.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Male and female, post-allo HCT within last 180 days, aged 2 months and older at time of signing informed consent form.
- Subject/Guardian willing and able to understand and provide written informed consent to participate in the study.
- In the investigator's judgement, the subject's clinical condition justifies treatment with IV BCV or IV CDV for AdV infection.
- Has adenoviremia, based on any of:
- AdV viremia DNA ≥10,000 IU/mL, OR
- Two consecutive and rising AdV viremia DNA results of ≥1,000 IU/mL at screening, OR
- AdV viremia DNA of ≥1,000 IU/mL, AND 1\. Lymphocyte count \<180/mm3, OR 2. Received T cell depletion, cord blood, or haploidentical transplant, OR 3. prior alemtuzumab, OR 4. anti-thymocyte globulin (ATG)
Exclusion criteria
- Subject received an allo-HCT with a matched sibling donor
- Subject received more than 5 mg/kg of CDV for any reason in the 21 days prior to first dose of study drug.
- Subject is allergic or hypersensitive to IV BCV or IV CDV or any of their components.
- Subject received anti-AdV-specific cell-based therapy within 3 weeks prior to W1D1 or an anti-AdV vaccine at any time.
- Subject has participated in any other investigational study within 30 days (or within 5.5 half-lives of the investigational product, whichever is longer) before signing the informed consent form (ICF), is currently participating in another interventional treatment trial with an investigational agent or is using an investigational device at the time of Screening.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
