Can a genetic trait stop chemotherapy from working? a trial aims to fix that
NCT ID NCT07743086
First seen Aug 03, 2026 · Last updated Aug 28, 2026 · Updated 2 times
Summary
This trial is testing whether a new dosing algorithm can help people with a genetic trait called Duffy-null get the full benefit of chemotherapy. Many people of African or Middle Eastern descent naturally have lower white blood cell counts (Duffy-null neutropenia), which can lead doctors to reduce or delay chemo doses. The study first develops an algorithm to guide dosing, then tests it in a larger group to see if it keeps treatment on track without increasing risks.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Standard of care chemotherapy with dose adjustment according to a new algorithm for Duffy-null positive patients
- What this could lead to
- If successful, this could lead to a personalized chemotherapy dosing approach that helps people with Duffy-null neutropenia receive full, effective doses without increased risk.
- What could go wrong
- The trial is early (Phase 1/2) and the algorithm is new, so it may not work as hoped. There are also risks from chemotherapy itself, such as infection or low blood counts.

Inclusion Criteria: * Participant must self-identify as being of Middle Eastern or African descent. * Participant must be diagnosed with histologically or cytologically confirmed solid organ cancer and be treatment naive. * Melanoma is allowed; sarcoma is not eligible. * Secondary malignancies are allowed. * Participants who have received only surgery alone as treatment are eligible * Participant must be between the ages of 18-80. * Participant or their legally authorized representative (LAR) must be able to understand a written informed consent document and be willing to sign it. Exclusion Criteria: * Participants with active and uncontrolled bacterial, viral, or fungal infection requiring IV antibiotics. • Participants may be eligible for the study if the infection is deemed to be under control per investigator's discretion. * Participants who have ever received cytotoxic chemotherapy. • Those who have already started a chemotherapy regimen with moderate likelihood of developing neutropenia will be considered for enrollment at the principal investigator's discretion. * Participants who are receiving concurrent chemo-radiation treatment. * Participants who are taking any other investigational drugs. * Participants who are pregnant or breastfeeding. * Participants that do not agree to be followed according to the study protocol or have cognitive or physical inability to follow the treatment plan.
