Monitoring paclitaxel levels in cancer patients

Pilot Feasibility Study of Paclitaxel Therapeutic Drug Monitoring in Cancer Patients

Wake Forest University Health Sciences · NCT03987555

This study is testing if checking the levels of the cancer drug paclitaxel in the blood can help doctors better manage treatment and reduce nerve damage in cancer patients with solid tumors.

What this trial studies

This observational cohort study aims to assess the feasibility of monitoring paclitaxel drug levels in the blood of cancer patients with solid tumors. It will explore the relationship between paclitaxel exposure and the development of neuropathic symptoms, a common side effect of the drug. The study will involve blood draws and surveys to evaluate chemotherapy-induced peripheral neuropathy and mitochondrial function. By measuring drug levels, the goal is to optimize paclitaxel dosing to effectively treat cancer while minimizing nerve damage.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older receiving paclitaxel treatment for solid tumors such as breast, lung, cervical, or ovarian cancers.

Not a fit: Patients not receiving paclitaxel or those with non-solid tumors may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more effective and safer chemotherapy regimens for cancer patients.

How similar studies have performed: While the specific approach of monitoring paclitaxel levels is novel, similar studies have shown the importance of drug monitoring in optimizing chemotherapy outcomes.

* Patients considered for curative or palliative chemotherapy with paclitaxel 60-175 mg/m2 with or without cisplatin, carboplatin, or bevacizumab
* Ability to understand and the willingness to sign an IRB-approved informed consent document (either directly or via a legally authorized representative)
* Patients with prior radiation treatment or surgery will not be disqualified from enrollment into the study, unless the aforementioned interventions resulted in peripheral neuropathy as a complication

Exclusion Criteria:

* Prior treatment with PTX, for any duration or indication
* Prior treatment with neurotoxic chemotherapy including any taxane, vinca alkaloid, platinum-containing agent, bortezomib, or thalidomide that has resulted in clinical symptoms of persistent, CTCAE grade II or higher peripheral neuropathy
* Concurrent enrollment in a clinical study of a neuroprotective intervention at the time of study initiation
* Any contraindication to Paclitaxel (e.g. history of allergic reaction to paclitaxel or Kolliphor EL)
* Current signs or symptoms of peripheral neuropathy at the time of enrollment, e.g. due to diabetes, HIV, or other conditions
* Known personal or family history of hereditary peripheral neuropathy (e.g. Charcot-Marie-Tooth disease)
