Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Postmenopausal women with estrogen receptor positive (ER+), human epidermal growth factor receptor 2 (HER2) negative metastatic breast cancer (MBC) who have progressed on combination therapy with an aromatase inhibitor and cyclin-dependent kinase 4/6 (CDK 4/6) inhibitor
  • Note: Postmenopausal females are considered of childbearing potential unless they are surgically or permanently sterile (have undergone a hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or they are naturally postmenopausal for at least 12 consecutive months. A high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a post-menopausal state in women not using hormonal contraception or hormonal replacement therapy. Documentation of postmenopausal status must be provided
  • Measurable disease per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST1.1)
  • Patients must have had tumor sequencing for evaluation of actionable PIK3CA or PTEN mutations performed in a Clinical Laboratory Improvement Act (CLIA) certified, College of American Pathologist (CAP) tested and bioinformatics-validated testing lab PRIOR to enrollment in this current protocol. If available patient tumor sequencing status must be provided to University of North Carolina (UNC) principal investigator (PI) at consent, and prior to any additional screening procedures. The testing may have been done at any time prior to enrollment. For patients who have not yet had tumor genomic assessment, after consultation with the PI, tumor specimens will be sent to the UNC Hospitals Clinical Molecular Genetics Laboratory for assessment of the Solid Tumor Mutation Panel. In this case, results of genetic testing by the UNC lab must be available prior to the first on study disease assessment (i.e., prior to day 1 of cycle 4). In this case, the study will cover the cost of the Solid Tumor Panel
  • Female subjects who are not of childbearing potential
  • Note: Because no dosing or adverse event data are currently available on the use of copanlisib in combination with fulvestrant in patients <18 years of age, and only postmenopausal women with ER+/HER2 negative MBC are eligible or appropriate for treatment with fulvestrant, children and pregnant or pre-menopausal women are excluded from this study

  • Subjects with moderate or severe hepatic impairment (ie, Child-Pugh B or C)
  • 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
  • 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; short-term (up to 7 days) systemic corticosteroids above 15 mg prednisolone or equivalent will be allowed for the management of acute conditions (e.g., treatment non-infectious pneumonitis); the use of corticosteroids as antiemetics prior to copanlisib administration will not be allowed
  • Uncontrolled intercurrent illness, including but not limited to, psychiatric illness/social situations that would limit compliance with study requirements
  • Major surgical procedure or significant traumatic injury (as judged by the investigator) within 28 days prior to start of treatment, or not recovered from major side effects, or open biopsy within 7 days before start of study treatment

  • Congestive heart failure > New York Heart Association (NYHA) class 2
  • Note: Class III NYHA Heart failure classification: Patients with cardiac disease resulting in marked limitation of physical activity. They are comfortable at rest. Less than ordinary activity causes fatigue, palpitation, dyspnea, or anginal pain
  • Note: Class IV NYHA Heart failure classification: Patients with cardiac disease resulting in the inability to carry on any physical activity without discomfort. Symptoms of heart failure or the anginal syndrome may be present even at rest. If any physical activity is undertaken, discomfort is increased.
  • Other cardiovascular-related abnormalities or therapy that prohibit study participation are:
  • Myocardial infarction less than 6 months before start of study medications
  • Unstable angina (angina symptoms at rest), new onset angina (begun within the last 3 months)
  • Uncontrolled arterial hypertension despite optimal medical management
  • Anti-arrhythmic therapy (exceptions: beta blockers or digoxin are permitted)
  • Pregnant or lactating (Pregnant women or women who are breastfeeding are excluded from this study because copanlisib is a PI3K inhibitor agent with the potential for teratogenic or abortifacient effects; there is no safety data in pregnancy; 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 and/or fulvestrant; fulvestrant may also cause fetal harm and based on animal studies, may impair fertility in females of reproductive potential)
  • Hepatitis B virus (HBV) or hepatitis C virus (HCV). All patients must be screened for HBV and HCV up to 28 days prior to study drug start using the routine hepatitis virus lab panel; patients positive for hepatitis B virus surface antigen (HBsAg) and/or hepatitis B virus core antibody (HBcAb) will be eligible if they are negative for deoxyribonucleic acid (DNA), these patients should receive prophylactic antiviral therapy; patients positive for anti-HCV antibody will be eligible if they are negative for HCV ribonucleic acid (RNA)

About this study

Official title: A Phase 2 Study of Copanlisib (BAY 80-6946) in Combination With Fulvestrant in Patients With Metastatic Breast Cancer Progressing After Aromatase Inhibitor Plus CDK 4/6 Inhibitor

This phase I/II trial studies the side effects and how well copanlisib works when given together with fulvestrant in treating patients with estrogen receptor positive (ER+) and human epidermal growth factor receptor 2 negative (HER2-) breast cancer that has spread to other places in the body (advanced) and progressing after prior treatment. HER2 and ER are two types of proteins called receptors that can affect the growth of breast cancer cells. Additionally, investigators hope to learn from this study if tumor genetic information is important for predicting whether this type of breast cancer will respond to fulvestrant and copanlisib. Copanlisib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Hormone therapy using fulvestrant may fight breast cancer by blocking the use of estrogen by the tumor cells. Giving copanlisib and fulvestrant may work better in treating patients with ER+ and HER2- breast cancer compared to fulvestrant alone.

Read the detailed description

PRIMARY OBJECTIVES:

  1. Establish safety of the combination of copanlisib and fulvestrant (FC). II. Evaluate the response rate (RR) of the combination of copanlisib and fulvestrant in patients with estrogen-receptor positive (ER+)/human epidermal growth factor receptor 2 (HER2) negative metastatic breast cancer that has previously progressed on aromatase inhibitor (AI)/cyclin dependent kinase (CDK) 4/6 inhibitor therapy.

SECONDARY OBJECTIVES:

  1. Estimate progression-free survival (PFS) in patients treated with copanlisib and fulvestrant stratifying by actionable PIK3CA mutation, actionable PIK3CA or PTEN mutation, or wild type PIK3CA and PTEN.

II. Estimate the RR in subjects with PTEN loss by immunohistochemistry (IHC) analysis performed retrospectively.

III. Evaluate toxicity in patients treated with FC in Phase II.

EXPLORATORY OBJECTIVES:

  1. Evaluate copanlisib pharmacokinetics (PK) when given in combination with fulvestrant.

II. Explore association between intrinsic subtype and response to FC therapy. III. Assess baseline levels and treatment-induced proteomic changes and correlate with response to FC.

IV. Evaluate circulating tumor deoxyribonucleic acid (DNA) (ctDNA) mutations at baseline and over time for response predictors at baseline, clonal evolution associated with treatment, and resistance mechanisms at disease progression.

  1. Evaluate PFS in patients with baseline ctDNA PIK3CA actionable mutations versus (vs.) those with wild type PK3CA.

VI. To evaluate genomic and gene expression changes in tumor cells and in associated tumor microenvironment before and after administration of copanlisib in combination with fulvestrant and at the time of progression.

VII. Evaluate circulating markers of metabolism before and after PI3K inhibitor therapy which may predict treatment response and resistance mechanisms.

OUTLINE:

Patients receive copanlisib intravenously (IV) over 1 hour on days 1, 8, and 15 and fulvestrant intramuscularly (IM) over 1-2 minutes on days 1 and 15 of cycle 1 and on day 1 beginning cycle 2. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 30 days.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Copanlisib and Fulvestrant in people with Anatomic Stage IV Breast Cancer AJCC v8 and Metastatic Breast Carcinoma, run by National Cancer Institute (NCI) at 7 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 26 inclusion and 35 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 25 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Dose limiting toxicity (DLT) (time frame: Up to 30 days post treatment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03803761.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Sep 2023.
