Description

Summary

This is a first-in-human Phase 1a/1b multicenter, open-label oncology study designed to evaluate the safety and anti-cancer activity of NX-2127 in patients with advanced B-cell malignancies.

Official Title

A Phase 1, Dose Escalation, Safety and Tolerability Study of NX-2127, a Bruton's Tyrosine Kinase (BTK) Degrader, in Adults With Relapsed/Refractory B-cell Malignancies

Details

Phase 1a (Dose Escalation) will evaluate the safety and tolerability of NX-2127 in adult patients with relapsed/refractory (R/R) B-cell malignancies, who have required and received at least 2 prior systemic therapies (or at least 1 prior therapy for patients with WM or PCNSL) and for which no other therapies are known to provide clinical benefit.

Phase 1b (Dose Optimization) will use a 2-stage design to further investigate the safety, tolerability, and preliminary efficacy of NX-2127 in R/R B-cell malignancies based on the dosage(s) selected in Phase 1a.

Stage 1 will enroll approximately 10 participants per group based on B-cell lymphoma/leukemia indication at a specific dose selected from the first part of the study. The Sponsor may decide to open Stage 2 for any given group after review of safety and anti-tumor activity data from Stage 1.

In Stage 2, an additional 10 participants will be enrolled at the dose from Stage 1 as well as 20 additional participants at a second alternative dose. Participants will be randomly assigned to one of the 2 dose levels in Stage 2.

Eligibility

You can join if…

Open to people ages 18 years and up

  • Patients must be ≥ 18 years of age
  • Patients must have measurable disease per disease-specific response criteria
  • Patients with indolent forms of NHL must meet the criteria requiring systemic treatment (i.e., iwCLL, IWG, Lugano Classification of Lymphoma response criteria, or International PCNSL Collaborative Group response criteria)
  • Patients with transformed lymphoma are eligible for the study with the exception of those detailed in

You CAN'T join if...

1: Prolymphocytic leukemia, MCL with blastoid

histology, MCL with pleomorphic morphology, or MCL with known TP53 mutation

  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 (non-PCNSL indications) or 0 - 2 (PCNSL patients)
  • Adequate organ and bone marrow function
  • Patients of child-bearing potential must use adequate contraceptive measures to avoid pregnancy for the duration of the study as defined in the protocol

Inclusion Criteria for Patients in Phase 1a:

  • Have histologically confirmed R/R CLL, SLL, WM, MCL, and MZL, FL, DLBCL, or PCNSL
  • Received at least 2 prior systemic therapies (or at least 1 prior therapy for patients with WM or PCNSL) and have no other therapies known to provide clinical benefit
  • Must require systemic therapy

Inclusion Criteria for Patients in Phase 1b:

  • Must have one of the following histologically documented R/R B-cell malignancies:
    • CLL/SLL whose disease has failed treatment with a BTKi;
    • MCL whose disease has failed treatment with BTKi and an anti-CD20 mAb-based regimen
    • FL or MZL whose disease has failed treatment with an anti-CD20 mAb-based regimen; or WM whose disease has failed treatment with a BTKi
    • PCNSL whose disease failed at least 1 prior line of treatment
    • DLBCL whose disease has failed treatment with an anti-CD20 mAb-based regimen and either: an anthracycline-based regimen; or an anti-CD19-based regimen, or another/ palliative regimen (either progressed post stem cell transplant or transplant-ineligible)

Exclusion Criteria:

  • Active, uncontrolled autoimmune hemolytic anemia or autoimmune thrombocytopenia
  • History of known/suspected other autoimmune disease (exception(s): patients with alopecia, vitiligo, resolved childhood atopic dermatitis, hypothyroidism, or hyperthyroidism that is clinically euthyroid at screening are allowed.)
  • Unable to swallow capsules or have a condition that may interfere in the delivery, absorption, or metabolism of the study drug
  • Bleeding diathesis, or other known risk for acute blood loss
  • Patients requiring ongoing treatment with warfarin or an equivalent vitamin K antagonist and within 7 days prior to the first dose of study drug
  • Prior radiotherapy within 2 weeks of planned start of study drug (excluding limited palliative radiation)
  • Toxicities from previous anticancer therapies must have resolved to baseline levels or to Grade 1 (except for alopecia, hypothyroidism with adequate replacement therapy, hypopituitarism with adequate replacement therapy, peripheral neuropathy or hematologic parameters meeting inclusion criteria).
  • Active known second malignancy. Exception: patients with non-metastatic, non-melanoma skin cancer are eligible
  • Patient has had major surgery (e.g. requiring general anesthesia) within 4 weeks before the planned first dose of study drug
  • Infection with human immunodeficiency virus (HIV)-1 or HIV-2. Exception: patients with well-controlled HIV (e.g., CD4 > 350/mm3 and undetectable viral load) are eligible.
  • Current active liver disease from any cause
  • Active viral reactivation (e.g., CMV or EBV)
  • Use of systemic corticosteroids exceeding 20 mg/day prednisone (or equivalent) for non-PCNSL indications within 15 days prior to the planned start of study drug. PCNSL patients may not exceed corticosteroid doses of 40 mg/day prednisone (or equivalent) and should be on a stable or decreasing dose for 7 days prior to planned study start.
  • Use of non-steroidal immunosuppressive drugs within 30 days prior to start of the study
  • Clinically significant, uncontrolled cardiac, cardiovascular disease, or history of myocardial infarction within 6 months of planned start of study drug
  • Administration of any strong cytochrome P450 3A (CYP3A) inducers or inhibitors for 14 days prior to the first dose of study drug, and any P-glycoprotein inhibitors (for 2 days) or moderate inducers of CYP3A for 7 days
