Parsaclisib Plus the Standard Drug Therapy in Patients With Newly Diagnosed, High Risk Diffuse Large B-cell Lymphoma

United States50 participantsStarted 2020-06-15

Plain-language summary

This phase I/Ib trial studies the side effects and best dose of parsaclisib with or without polatuzumab-vedotin (Pola) plus the standard drug therapy (rituximab, cyclophosphamide, doxorubicin hydrochloride, vincristine sulfate, and prednisone \[PaR-CHOP\]) and to see how well they work compared with R-CHOP alone in treating patients with newly diagnosed, high risk diffuse large B-cell lymphoma. Parsaclisib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Rituximab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Polatuzumab-vedotin is a monoclonal antibody, called polatuzumab, linked to a chemotherapy drug, called vedotin. Polatuzumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as anti-CD79b receptors, and delivers vedotin to kill them. Drugs used in chemotherapy, such as cyclophosphamide, doxorubicin hydrochloride, and vincristine sulfate, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Anti-inflammatory drugs, such as prednisone, lower the body's immune response and are used with other drugs in the treatment of some types of cancer. It is not yet known if giving parsaclisib and R-CHOP together works better than R-CHOP alone in treating patients with high risk diffuse large B-cell lymphoma.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Age \>= 18 years * Newly diagnosed, untreated, histologically confirmed diffuse large B-cell lymphoma expressing the CD20 antigen, with ANY of the following: * Non-germinal center B-cell (GCB) subtype by Hans algorithm * Myc expression \>= 40% by immunohistochemistry (IHC) * Bcl-2 expression \>= 50% by IHC * Myc expression \>= 40% AND Bcl-2 expression \>= 50% by IHC (double expressor) * MYC rearrangement by fluorescence in situ hybridization (FISH) * Or high-grade B-cell lymphoma with MYC rearrangement AND BCL2 and/or BCL6 rearrangement (double-hit or triple-hit lymphoma) but not a candidate for more aggressive chemotherapy (such as cyclophosphamide, Oncovin \[vincristine\], doxorubicin, \[CODOX\]-methotrexate \[M\]- ifosfamide, Vepesid \[etoposide\], Ara-C \[cytarabine\] \[IVAC\]) * NOTE: Patients with a new diagnosis of concurrent DLBCL and an indolent lymphoma (previously undiagnosed, such as follicular lymphoma or marginal zone lymphoma) are eligible. However, patients with a known prior diagnosis of indolent lymphoma with new transformation to DLBCL (i.e., transformed lymphoma) are not eligible * Ann Arbor stages II (bulky disease, i.e., \>= 5 cm, or not a candidate for combined modality treatment with R-CHOP plus radiotherapy), III, or IV * Measurable disease (at least 1 lesion of \>= 1.5 cm in one diameter) as detected by computed tomography (CT) or the CT images of PET/CT. Skins lesions can be used if the area is \>= 2 cm in at…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
