Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

A study to evaluate ALVR106; an allogeneic, off-the-shelf multi-virus specific T cell therapy that targets four community acquired respiratory viruses: respiratory syncytial virus (RSV), influenza, human metapneumovirus (hMPV), and/or parainfluenza virus (PIV) following hematopoietic cell transplant (HCT) and solid organ transplant (SOT).

Read the detailed description

The study hypothesis is that the administration of ALVR106, multi-virus specific T cells, plus standard of care, to post HCT or SOT patients suffering from infection with any of the four targeted viruses (RSV, influenza, hMPV, and/or PIV) will be safe and demonstrate shorter time to resolution of the respiratory viral infection (as measured by resolution of symptoms and viral load clearance in nasal swab) compared to patients treated with placebo.

This trial will consist of two parts: Part A is Dose Escalation and Part B is Cohort Expansion.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Undergone hematopoietic cell transplantation (HCT) ≥21 days or solid organ transplantation (SOT) ≥28 days prior to study treatment administration
  • Detection of at least 1 target virus of interest (ie, RSV, influenza, hMPV, and/or PIV)
  • Diagnosis of Upper or mild Lower Respiratory Tract Infection

Exclusion criteria

Exclusion Criteria:

  • Ongoing therapy with high-dose systemic (ie, prednisone equivalent dose >0.5 mg/kg/day)
  • Infection by novel coronavirus disease 2019 (COVID-19)
  • For HCT patients, evidence of Grade >2 ; and for SOT patients, any history or evidence of GVHD
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

GVHD (graft-versus-host disease)

After a transplant from a donor, the donor’s immune cells attack the recipient’s body, often the skin, gut or liver.

What researchers measure

Primary outcomes

  1. Number of Participants With Treatment-emergent Adverse Events (TEAEs) (Part A)

    A TEAE was defined as an adverse event (AE) with a start date and time on or after the first dose of study treatment. A serious AE (SAE) was an AE that met at least one of the following serious criteria: fatal, life-threatening, requires in-patient hospitalization or prolongation of existing hospitalization; resulted in persistent or significant disability/incapacity; was a congenital anomaly/birth defect; or other important medical event. TEAEs of special interest (AESI) included new/worsening graft versus host disease, graft failure or rejection, cytokine release syndrome, infusion related reactions, new/worsening pneumonitis, and progressive dyspnea. Treatment-related refers to the assessment of a relationship between study treatment and the event by the investigator.

    Time frame: Day 1 up to 12 months

  2. Change in Viral Load From Baseline to Day 28 (Part B)

    Change from Baseline in viral load as measured by quantitative PCR of nasal swab

    Time frame: Baseline and Day 28 (Part B)

Secondary outcomes

  1. Identify the Recommended Phase 2 Dose (RP2D) (Part A)

    The RP2D was to be determined after the maximum tolerated dose was reached in Part A.

    Time frame: Day 1 up to 12 months

  2. Change in Viral Load Cycle Threshold From Baseline to Day 28 (Part A)

    Viral load was measured by quantitative polymerase chain reaction (PCR) of nasal swab specimens. The cycle threshold value categorizes the concentration of viral genetic material in a participant's swab specimen, and the cycle threshold value represents the number of PCR cycles required to amplify the viral genetic material (as measured by fluorescence) to a detectable level that is distinguishable from baseline fluorescence, providing an estimate of viral load. Lower cycle threshold values indicate higher viral load and high values indicate lower viral load. A positive change from baseline indicates a decrease in the viral load. The baseline measurement was from a pre-dose nasal swab.

    Time frame: Baseline and Day 28

  3. Number of Participants With Treatment-emergent Adverse Events (TEAEs) (Part B)

    Time frame: Day 1 up to 12 months

  4. Percentage Reduction in Viral Load From Baseline to Month 6 (Part B)

    Time frame: Day 1 and Month 6

Baseline characteristics

The modified intent-to-treat population for Part A which included all randomized participants who received any amount of ALVR106 or placebo and had confirmed virologic infection of interest at baseline (detectable viral load). One participant randomized to the placebo cohort did not receive study treatment and is not included. Due to early study termination, no participants were enrolled into Part B and therefore Part B is not included in the baseline analysis population.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 6, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
