Could longer infusions make chemo safer for frail patients?
NCT ID NCT05183126
First seen Jun 25, 2026 · Last updated Jul 02, 2026 · Updated 2 times
Summary
This study looks at whether giving the chemotherapy drug paclitaxel over a longer period (2-3 hours instead of 1 hour) can help cancer patients with low muscle mass achieve safer drug levels. Researchers will compare drug concentrations in 22 women with breast, stomach, or esophageal cancer. The goal is to see if adjusting infusion time based on muscle mass normalizes exposure to the drug.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Paclitaxel (Taxol)
- What this could lead to
- If successful, this could lead to safer and more effective dosing of paclitaxel for cancer patients with low muscle mass.
- What could go wrong
- This is a small, early-phase pharmacokinetic study with only 22 participants. It focuses on drug levels, not direct treatment outcomes, so benefits for patients are uncertain.

Inclusion Criteria: * Planned paclitaxel 80 mg/m\^2, 1-hour infusion * Evaluable computed tomography (CT) scan, positron emission tomography computed tomography (PET-CT) scan, or MRI scan (e.g. scan of the chest, abdomen, or pelvis for any indication w/in 1 year) * Female * ≥ 18 years old * Adequate organ function to receive paclitaxel treatment as defined in the protocol * Ability to understand and the willingness to sign a written informed consent Exclusion Criteria: * Concomitant administration of any moderate or strong inducer or inhibitor of CYP2C8, including rifampin or clopidogrel. * History of hypersensitivity reaction to paclitaxel or any components of paclitaxel (e.g., Cremophor EL) that precludes continued treatment with standard dose and infusion length * Pregnant or nursing * Receiving any other dose (i.e., not 80 mg/m2) or infusion rate (i.e., not 60 minute infusion) either due to toxicity during a previous cycle or any other reason
