Study Description

Brief Summary:

This research study is examining the effect of adding a fixed duration of copanlisib to ibrutinib or acalabrutinib in select participants who have been on ibrutinib or acalabrutinib for at least six months for relapsed/refractory chronic lymphocytic leukemia (CLL).

The names of the study drugs involved in this study are:

• Copanlisib
• Ibrutinib
• Acalabrutinib

Condition or disease	Intervention/treatment	Phase
Chronic Lymphocytic Leukemia (CLL)	Drug: Ibrutinib; Drug: Copanlisib; Drug: Acalabrutinib	Phase 2

Detailed Description:

This is an open-label, phase II study, adding copanlisib to ibrutinib or acalabrutinib in select participants who are receiving ibrutinib for relapsed/refractory CLL.

Copanlisib has not been approved by the U.S. Food and Drug Administration (FDA) for CLL, but it has been approved for use in relapsed/refractory follicular lymphoma. Ibrutinib and acalabrutinib are approved by the FDA as a treatment option for CLL.

This research study is:

• Trying to understand what effects, good or bad, treatment with copanlisib in combination with ibrutinib or acalabrutinib has in select participants who are receiving ibrutinib for relapsed/refractory CLL
• Determining if this approach is better or worse than the usual approach for this type of cancer
• Determining whether genomic changes in CLL cells and changes in immune response make treatment with the study drugs more or less effective

The research study procedures include screening for eligibility and study treatment including evaluations and follow up visits.

Participants will receive combination therapy for six months before resuming ibrutinib alone. They will continue therapy for as long as they do not have serious side effects and their disease does not get worse and will be followed for up to 5 years.

It is expected that about 30 people will take part in this research study.

Bayer HealthCare Pharmaceuticals is supporting this research study by providing the study drug, copanlisib. Ibrutinib and acalabrutinib will be obtained from commercial supply.

Experimental: Ibrutinib + Copanlisib/Acalabrutinib; During 28 day study treatment cycle, participants will: Take Ibrutinib (daily) or Acalabrutinib (twice a day) at predetermined dose for as long as there are no serious side effects and disease progression; Receive intravenous infusion of Copanlisib at a predetermined dose days 1, 8 and 15 for cycles 1-6.

Outcome Measures

Primary Outcome Measures :

1. Complete response (CR) Rate [ Time Frame: 6 months ]
   Rate of complete response (CR) by 2018 IWCLL criteria following the addition of six months of copanlisib to the therapy of patients with SD or PR or PR-L on ibrutinib or acalabrutinib in the relapsed/refractory setting.

Secondary Outcome Measures :

1. Number of Participants with Treatment Related Adverse Events as Assessed by CTCAE ver. 5.0. [ Time Frame: 6 months ]
   Adverse events will be collected and reported as percentages
2. Duration of Response (DOR) [ Time Frame: 3 years ]
   Legnth of time the patients respond to therapy
3. Progression-free Survival (PFS) [ Time Frame: 3 years ]
   The time from registration to progression or death due to any cause. Participants alive without disease progression are censored at date of last disease evaluation.
4. Overall Survival (OS) [ Time Frame: 3 years ]
   The time from registration to death due to any cause or censored at date last known alive.
