Phase I Study of PI3(Phosphoinositol 3)-Kinase Inhibitor BAY80-6946 With Paclitaxel in Patients With Advanced Cancer
- Registration Number
- NCT01411410
- Lead Sponsor
- Bayer
- Brief Summary
This open label Phase 1 study involves treating subjects with advanced cancer with BAY80-6946 in combination with paclitaxel. It will determine the maximum tolerated dose (MTD) and the recommended Phase 2 dose (RP2D) of BAY80-6946 in combination with paclitaxel. The trial will involve multiple participating sites from the US. Following determination of the MTD, an expansion cohort of 20 evaluable subjects with breast cancer was planned. Finally, 16 patients have been enrolled to treatment (Cohort 3). A new expansion cohort with modified dosing cohort is now introduced (Cohort 4: breast cancer expansion cohort with modified dosing) in which another 20 subjects are planned to be enrolled to treatment.

Inclusion Criteria
- Subjects must have defined tumor classification (ie, TNBC, HER2+ or Luminal) for enrollment. If tumor classification is not available the subject cannot be enrolled. Tumor classification can be based on analysis of archived tumor tissue, or analysis of tumor tissue collected at any time proximal to screening. Subject profile can also be derived from analysis of fresh tumor tissue obtained during screening. Shipment of specimens (archival or fresh tumor tissue, blood, and plasma) to a central lab can take place after subject enrollment.
- No prior paclitaxel treatment for subjects in the dose escalation phase. MTD cohort expansion subjects may have had prior paclitaxel, but must not have experienced moderate or severe hypersensitivity reactions to the drug. Peripheral neuropathy must be Grade ≤ 1.
- Histological or cytological documentation of non-hematologic malignant solid tumor, excluding primary brain or spinal tumors. Patients with prior central nervous system metastases are eligible if all of the following apply: -- Definitive treatment for all lesions (eg, surgery, radiation) was completed at least three months prior to enrollment -- All lesions must be stable or improving on MRI scan performed within one month of enrollment -- All symptoms of the prior CNS metastases are stable.
- At least one measurable lesion or evaluable disease, as per RECIST 1.1
- ECOG Performance Status Assessment of 0 or 1
- Life expectancy of at least 12 weeks

- History of cardiac disease; congestive heart failure (CHF) >NYHA Class II; active coronary artery disease, myocardial infarction within 6 months prior to study entry; new onset angina within 3 months prior to study entry or unstable angina, or ventricular cardiac arrhythmias requiring anti-arrhythmic therapy

Group Intervention Description Copanlisib (BAY80-6946) Copanlisib (BAY80-6946) The treatment of consists of repetitive cycles, each over 4 weeks. It continues until disease progression or limiting toxicity. If paclitaxel is discontinued for toxicity, BAY80-6946 may continue at the discretion of the investigator if a clinical benefit (response or stable disease for 6 months) is noted.
