Study Summary

This trial is studying a new vaccine, COH04S1, to see if it is better than the EUA SARS-CoV-2 vaccine in reducing the chances of contracting COVID-19 or developing a severe form of COVID-19 disease in patients with blood cancer who have received stem cell transplant or cellular therapy.

Who is the study for?
Adults with blood cancers who've had stem cell transplants or CAR T-cell therapy at least 3 months ago. They must be in good health, not pregnant, agree to birth control, and have normal organ function tests. Those who got a COVID-19 vaccine after their therapy or have certain medical treatments or conditions are excluded.Check my eligibility
What is being tested?
The trial is testing GEO-CM04S1, a synthetic MVA-based SARS-CoV-2 vaccine against standard mRNA vaccines in blood cancer patients post-transplant or cellular therapy. It aims to see if GEO-CM04S1 offers better protection from COVID-19.See study design
What are the potential side effects?
Potential side effects aren't specified but may include typical vaccine reactions like soreness at the injection site, fever, fatigue, muscle pain. Severe allergic reactions could occur but are rare.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

To what extent is the patient population engaged in this research project?

"Affirmative. According to the information available on clinicaltrials.gov, this medical trial is actively enrolling participants; it was initially posted on September 27th 2021 and its most recent update occurred on November 2nd 2021. The study intends to admit 240 patients across a single site."

Answered by AI

Are there other research initiatives studying the efficacy of a COVID-19 Vaccine?

"Currently, the research efforts on a COVID-19 Vaccine are extensive. 26 trials are in progress, with 5 of them reaching phase 3. Although Miami is the epicentre for this work, 180 other sites have been enlisted to participate as well."

Answered by AI

Are there any vacancies left in this trial for participants?

"As verified on clinicaltrials.gov, this trial is presently taking in patients. It was first made available to the public on September 27th 2021 and recently updated on November 2nd 2021."

Answered by AI

What risks could be associated with COVID-19 Vaccine administration?

"Our team at Power assigned a score of 2 to the safety profile of the COVID-19 Vaccine, as there is some evidence that it is safe but no data yet showing efficacy."
