VoxSCAN Trial Summary

This trial will test whether the new drug Voxelotor can improve hemoglobin levels and reduce the incidence of worsening anemia in patients with sickle cell disease.

Who is the study for?
Children aged 4-17 with sickle cell anemia can join this trial if they have stable doses of hydroxyurea, no severe heart issues, and are not on chronic transfusion therapy. They must be able to take oral meds and follow the study plan. Girls who can get pregnant need a negative pregnancy test and agree to use birth control.Check my eligibility
What is being tested?
The trial is testing Voxelotor's effect on brain blood flow in kids with sickle cell disease. It checks if higher hemoglobin from the drug lowers stress in the brain. Participants will regularly take Voxelotor orally and undergo special assessments.See study design
What are the potential side effects?
Possible side effects of Voxelotor include headache, diarrhea, abdominal pain, nausea, fatigue, rash, fever; however specific side effects related to cerebral hemodynamics are being studied.

Frequently Asked Questions

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

Is this investigation into a new therapeutic approach?

"Ever since 2016, Voxelotor has been subject to rigorous medical research. Global Blood Therapeutics were the first sponsor of a study in 2016 that involved 155 participants and granted it Phase 2 drug approval. Currently, 7 studies are being conducted around 39 cities and 14 countries worldwide."

Answered by AI

Has there been any prior research on the efficacy of Voxelotor?

"Presently, there are seven investigations into the efficacy of Voxelotor. Of those studies, three occupy their final phase in the clinical trial process. Whilst Philadelphia is a hub for this research, 139 other sites across America also facilitate trials with this medication."

Answered by AI

Is enlistment currently available for this trial?

"Affirmative. The records provided by clinicaltrials.gov suggest that the recruitment for this medical study is ongoing, with an initial posting on March 28th 2022 and most recent update on August 23rd 2022. A total of 12 patients are needed from two distinct sites to complete the trial."

Answered by AI

Has Voxelotor received clearance from the FDA?

"Limited clinical data exists to attest to the safety of Voxelotor, thus it received a rating of 2. This Phase 2 trial has yet to reveal any evidence that supports its efficacy."

Answered by AI

Is this research program open to participants under the age of seventy?

"Eligible candidates for this investigation must be aged between 4 and 17 years old. Additionally, there are 212 trials involving minors and 239 studies dedicated to patients above the age of 65."

Answered by AI

How many participants have enrolled in this research project?

"Affirmative. Clinicaltrials.gov confirms that, as of August 23rd 2022, this medical experiment is actively recruiting patients to fill 12 positions in 2 different locations since its commencement on March 28th 2022."

Answered by AI

Is there an opportunity for me to join this investigation?

"This medical trial is accepting up to twelve participants between the ages of four and seventeen who have been diagnosed with anemia, sickle cell. Several criteria must be met for consideration including: written informed parental/guardian consent and participant assent acquired in accordance with International Conference on Harmonization (ICH) guidelines, stability of hydroxyurea therapy dosage within three months preceding study commencement, ability to orally ingest medications combined with willingness to adhere to daily voxelotor administration and scheduled DCS/NIRS assessments, negative pregnancy test at screening if female patient is sexually active or barriers methods such as contraception required by male patients during their participation"
