[0002] This application relates to methods of treating a patient having a B-cell proliferative disorder with a therapeutically effective amount of a chimera degradation activating compound (CDAC) that targets Bruton’s Tyrosine Kinase (BTK) .BACKGROUND
[0003] BTK is a non-receptor intracellular kinase that is a member of the Tec (tyrosine kinase expressed in hepatocellular carcinoma) family. As part of the B-cell receptor signaling pathway, BTK plays a crucial role in the survival and proliferation of malignant cells and in their interaction with the tumor microenvironment. BTK inhibitors have been approved for treating patients with certain B-cell proliferative disorder, including, for example, chronic lymphocytic leukemia (CLL) , macroglobulinemia (WM) , mantle cell lymphoma (MCL) , and marginal zone lymphoma (MZL) .
[0004] However, many patients experience disease progression in part due to resistance mutations within BTK that arise during treatment with both covalent or non-covalent BTK inhibitors. Therapeutic agents that can overcome BTK inhibitor resistance are needed. It could be an important advance to treat patients who have developed BTK inhibitor resistance with an agent that inhibits BTK-mediated signaling via an alternative mechanism.

[0032] As described in Example 1, Compound 1 is being studied in an on-going multicenter, Phase 1 / 2, open-label, and first-in-human trial in patients with relapsed / refractory B-cell proliferative disorders. Preliminary results from this on-going clinical trial demonstrate meaningful clinical responses with a short time to response in high-risk, heavily pretreated population of patients with a range of B-cell malignancies. These B-cell malignancies including, for example, chronic lymphocytic leukemia (CLL) , small lymphocytic lymphoma (SLL) , macroglobulinemia (WM) , mantle cell lymphoma (MCL) , marginal zone lymphoma (MZL) , and follicular lymphoma (FL) . The prior treatment the patients had received included a covalent BTK inhibitor, non-covalent BTK inhibitor, BCL-2 inhibitor, and / or chimeric antigen receptor (CAR) T-cell therapy (or CAR-T therapy) . The covalent BTK inhibitor was selected from zanubrutinib, ibrutinib, acalabrutinib, orelabrutinib, spebrutinib, and TG-1701. The noncovalent BTK inhibitor was selected from pirtobrutinib, nemtabrutinib, vecabrutinib, and LP-168. The BCL2 inhibitor was selected from venetoclax, lisaftoclax, LP-108, sonrotoclax, and gossypol. The CAR-T therapy was selected from axicabtagene ciloleucel, brexucabtagene autoleucel, tisagenlecleucel, and lisocabtagene maraleucel. Some of the patients who responded had a BTK mutant form.
[0033] Further among the responsive patients, they were either previously treated with a covalent BTK inhibitor, with a non-covalent BTK inhibitor, with a CAR-T therapy, with both covalent and non-covalent BTK inhibitors, with a covalent BTK inhibitor and a BCL-2 inhibitor, with a covalent BTK inhibitor and a CAR-T therapy, with a covalent BTK inhibitor, non-covalent BTK inhibitor, and BCL-2 inhibitor, or with a covalent BTK inhibitor, a non-covalent BTK inhibitor, and a CAR-T therapy.
[0034] Moreover, responses occurred starting at the lowest dose level (2 / 4 patients receiving 50 mg); at the 100 mg level (5 / 10 patients receiving 100 mg) , at the 200 mg level (8 / 9 patients receiving 200 mg) , and at the 500 mg level (1 / 1 patients receiving 500 mg) .
[0035] In a high-risk, heavily pretreated population of patients with CLL / SLL all treated with covalent BTK inhibitors, the ORR was 70%. A complete response (CR) was observed in the lowest dose group (i.e., 50 mg daily dose) of a MCL patient.
[0036] Preliminary data also showed substantial reductions in BTK protein (mutant or non-mutant form) levels in peripheral blood and tumor tissue, even at the lowest dose (See FIG. 1A and 1B) , demonstrating proof-of-concept of a strong, on-target effect.
[0037] The safety profile of Compound 1 collected from the 50 patients appears tolerable to date with a single DLT (rash) reported. Discontinuations due to treatment-emergent AEs (TEAEs) were low (2 of 50 patients) and no atrial fibrillation or hypertension has been reported so far. IV. Embodiments

Patients ranged in age from 25 to 91 years, with an overall median age of 70.5 years. Median number of prior therapies were 4 (range 2-10) : 80%were previously treated with a covalent BTK inhibitor selected from zanubrutinib, ibrutinib, acalabrutinib, orelabrutinib, spebrutinib, and TG-1701, 14%a noncovalent BTK inhibitor selected from pirtobrutinib, vecabrutinib, nemtabrutinb, and LP-168, 56%a BCL2 inhibitor selected from venetoclax, lisaftoclax, LP-108, sonrotoclax, and gossypol, and 56%discontinued BTK inhibitor due to PD. In CLL / SLL, del17p (17p deletion) / TP53 mutation (n=11) and unmutated IGHV (n = 16) were frequent.
[0233] Compound 1 was dosed daily by mouth in 28-day cycles. The aforementioned 50 patients were enrolled at 5 dose levels (50 mg, 4; 100 mg, 14; 200 mg, 15; 350 mg, 13; 500 mg, 4; once daily, QD) . Results
[0234] BTK protein levels were measured at steady state (Week4 / Week 5, day 1) in whole blood lysates by ELISA (FIG. 1A) . Percentage of BTK-positive neoplastic B-cells were also measured by immunohistochemistry in paired pretreatment and steady state tumor tissue collected from lymph nodes or bone marrow (FIG. 1B, Week 13 were shown) . Both FIG. 1A and 1B showed deep, sustained reductions in BTK protein levels in peripheral blood and tumor tissue, even at the lowest dose.
[0235] Responses by dose and responses by histology in evaluable patients were summarized in Table 1 and Table 2, respectively.
