Testing the Addition of an Anti-cancer Drug, Copanlisib, to the Usual Maintenance Treatment (Trastuzumab and Pertuzumab) After Initial Chemotherapy in a Phase Ib/II Trial for Advanced HER2 Positive Breast Cancer
Study Details
Study Description
Brief Summary
This phase Ib/II trial studies the side effects and best dose of copanlisib when given together with trastuzumab and pertuzumab and to see how well they work after induction treatment in treating patients with HER2 positive stage IV breast cancer with PIK3CA or PTEN mutation. Copanlisib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Trastuzumab is a form of "targeted therapy" because it works by attaching itself to specific molecules (receptors) on the surface of cancer cells, known as HER2 receptors. When trastuzumab attaches to HER2 receptors, the signals that tell the cells to grow are blocked and the cancer cell may be marked for destruction by the body's immune system. Monoclonal antibodies, such as pertuzumab, may kill tumor cells that are left after chemotherapy. The addition of copanlisib to the usual treatment (trastuzumab and pertuzumab) could shrink the cancer or stabilize it for longer duration as compared to the usual treatment alone.

(Phase Ib) II. To assess the benefit of adding copanlisib to trastuzumab and pertuzumab in HER2-positive metastatic breast cancer patients with PIK3CA mutations or PTEN mutation receiving maintenance therapy after induction treatment, as measured by progression free survival (PFS). (Phase II)
SECONDARY OBJECTIVES:

-
Prior exposure to any PI3K, AKT or mTOR inhibitors. History of allergic reactions attributed to compounds of similar chemical or biologic composition to copanlisib, PI3K inhibitors, or HER2 inhibitors
-
Copanlisib is primarily metabolized by CYP3A4. Therefore, the concomitant use of strong inhibitors of CYP3A4 (e.g., ketoconazole, itraconazole, clarithromycin, ritonavir, indinavir, nelfinavir and saquinavir), and strong inducers of CYP3A4 (e.g. rifampin, phenytoin, carbamazepine, phenobarbital, St. John's wort) are not permitted from 14 days prior to enrollment until the end of the study. Other medications that are prohibited while on copanlisib treatment:
-
Herbal medications/preparations (except for vitamins)
-
Anti-arrhythmic therapy other than beta blockers or digoxin
-
Because the lists of these agents are constantly changing, it is important to regularly consult a frequently-updated medical reference for a list of drugs to avoid or minimize use of. As part of the enrollment/informed consent procedures, the patient will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the-counter medicine or herbal product
-
Systemic corticosteroid therapy at a daily dose higher than 15 mg prednisone or equivalent is not permitted while on study. Previous corticosteroid therapy must be stopped or reduced to the allowed dose at least 7 days prior to the computed tomography (CT)/magnetic resonance imaging (MRI) screening. If a patient is on chronic corticosteroid therapy, corticosteroids should be de-escalated to the maximum allowed dose before the screening. Patients may be using topical or inhaled corticosteroids
-
Patients with non-healing wound, ulcer, or bone fracture
-
Pregnant women are excluded from this study because copanlisib is a PI3K inhibitor agent with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with copanlisib, breastfeeding should be discontinued if the mother is treated with copanlisib. These potential risks may also apply to other agents used in this study
-
Patients are eligible to receive standard of care therapy that would confer clinical benefit to the patient
