Background:

Blood cancers that affect B cells are often treated with drugs that block or inhibit a protein in cancer cells called BTK. Some tumors become resistant to these drugs. Researchers want to learn if a new drug (NX-2127) that degrades BTK can help.

Objective:

To learn if NX-2127 can be used to treat certain B-cell blood cancers.

Eligibility:

Adults aged 18 and older with certain B-cell blood cancers who have received at least 2 prior treatments that failed (or 1 for people with Waldenstrom macroglobulinemia [WM]). Cancer types include diffuse large B-cell lymphoma, chronic lymphocytic leukemia/small lymphocytic lymphoma, follicular lymphoma, marginal zone lymphoma, mantle cell lymphoma, and WM.

Design:

Participants will be screened with:

Medical history

Physical exam

Blood and urine tests

PET and/or CT scans

Heart tests

Lymph node biopsy, if needed

Bone marrow biopsy/aspirate, if needed

Participants will take NX-2127 by mouth once daily or every-other day. They will fast for 2 hours before and after taking the drug. On some days, they will fast overnight. They will take the drug until they have bad side effects or their cancer gets worse.

Participants will have weekly study visits for the first 2 months of treatment. Some visits may last 8 hours or more. For the next 2 months, they will have visits every 2 weeks. After that, they will have monthly visits. At visits, they will repeat some screening tests.

Participants will have safety follow-up visits 7 and 30 days after treatment ends. Then they will have follow-up visits in person or by phone every 3 months for 1 year.

--Any other significant cardiac condition (e.g., pericardial effusion, restrictive cardiomyopathy, severe untreated valvular stenosis, or severe congenital heart disease)

-Any other medical or psychiatric condition or social situation that, in the opinion of the Investigator, would compromise patient safety, or interfere with the objectives or the protocol or completion of treatment per protocol

-Administration of any strong inducers or inhibitors of cytochrome P450 3A (CYP3A) for 14 days (or 5 half-lives, whichever is longer) prior to the first dose of study drug, any moderate inducers of CYP3A for 7 days (or 5 half-lives, whichever is longer), and inhibitors of P-glycoprotein for 2 days (or 5 half-lives, whichever is longer)

NOTE: Investigators should ensure that all study enrollment criteria have been met at Screening. If a patient's status changes (including laboratory results or receipt of additional medical records) after Screening but before the first dose of study drug is given such that he or she no longer meets all eligibility criteria, supportive treatment may be administered according to local standards of care, if necessary, so that eligibility criteria can be met and laboratory test(s) may be repeated to determine if the patient qualifies for the study. If rescreening occurs within 28 days of the signing of the original informed consent, it is only necessary to perform the procedure(s)/assessment(s) that did not originally meet the eligibility criteria; all other initial Screening procedures/assessments do not need to be repeated. If rescreening is delayed more than 28 days from the signing of the original informed consent, patients must be re-consented and repeat all Screening procedures/assessments that fall outside of a 28-day window prior to Cycle 1 Day 1. Patients may be rescreened more than once with Medical Monitor approval.

Be aware that many laboratory tests, including but not limited to cardiovascular diagnostic tests and hormone tests, which use biotin technology are potentially affected, and incorrect test results may be generated if there is biotin in the patient s specimen. Know that biotin is found in multivitamins, including prenatal multivitamins, biotin supplements, and dietary supplements for hair, skin, and nail growth in levels that may interfere with laboratory tests. A threshold high level biotin dose has not yet been defined by the Food and Drug Administration (FDA).

Study Investigators should discuss with study patients about any biotin supplements they may be taking. For patients taking biotin supplements at doses > 30 microg/day, the Investigator should assess if it is possible to discontinue use of these supplements. In cases where the Investigator believes a patient is taking high doses of biotin and discontinuation of this supplementation is not in the best interest of the patient, the Investigator should contact the Medical Monitor to assess the potential impact on study laboratory test results.

NOTE: Investigators should ensure that all study enrollment criteria have been met at Screening. If a patient's status changes (including laboratory results or receipt of additional medical records) after Screening but before the first dose of study drug is given such that he or she no longer meets all eligibility criteria, supportive treatment may be administered according to local standards of care, if necessary, so that eligibility criteria can be met and laboratory test(s) may be repeated to determine if the patient qualifies for the study. If rescreening occurs within 28 days of the signing of the original informed consent, it is only necessary to perform the procedure(s)/assessment(s) that did not originally meet the eligibility criteria; all other initial Screening procedures/assessments do not need to be repeated. If rescreening is delayed more than 28 days from the signing of the original informed consent, patients must be re-consented and repeat all Screening procedures/assessments that fall outside of a 28-day window prior to Cycle 1 Day 1. Patients may be rescreened more than once with Medical Monitor approval.

Be aware that many laboratory tests, including but not limited to cardiovascular diagnostic tests and hormone tests, which use biotin technology are potentially affected, and incorrect test results may be generated if there is biotin in the patient s specimen. Know that biotin is found in multivitamins, including prenatal multivitamins, biotin supplements, and dietary supplements for hair, skin, and nail growth in levels that may interfere with laboratory tests. A threshold high level biotin dose has not yet been defined by the Food and Drug Administration (FDA).

Study Investigators should discuss with study patients about any biotin supplements they may be taking. For patients taking biotin supplements at doses > 30 microg/day, the Investigator should assess if it is possible to discontinue use of these supplements. In cases where the Investigator believes a patient is taking high doses of biotin and discontinuation of this supplementation is not in the best interest of the patient, the Investigator should contact the Medical Monitor to assess the potential impact on study laboratory test results.
