A Study of CA-4948 in Patients With Relapsed or Refractory Hematologic Malignancies
- for people ages 18 years and up (full criteria)
- at UCLA
- study startedestimated completion
This is a multi-center, open-label trial to evaluate oral administration of emavusertib (CA-4948) in adult patients with relapsed/refractory hematologic malignancies. Part A will evaluate escalating doses of emavusertib either as monotherapy (Part A1) or in combination with ibrutinib for non- Hodgkin's Lymphoma (NHL) (Part A2). Once the combination dose has been determined, Part B will comprise an expansion phase to assess efficacy (CR rate or ORR) and safety of the RP2D of emavusertib and ibrutinib in 4 Non-Hodgkin Lymphoma (NHL) disease-specific cohorts: - Cohort 1 - Marginal zone lymphoma (MZL) - Cohort 2 - activated B-cell (ABC) diffuse large B-cell lymphoma (DLBCL) or extranodal subtypes: Leg-, testicular-, or not otherwise specified (NOS)-type - Cohort 3 - Primary central nervous system lymphoma (PCNSL) - Cohort 4 - Patients receiving ibrutinib monotherapy who have developed adaptive, secondary resistance. Indications include: - Mantle Cell Lymphoma (MCL), MZL - Indications for which ibrutinib is National Comprehensive Cancer Network (NCCN)-listed (e.g., PCNSL) - Patients with NHL and known myddosome mutations - Patients may be candidates for maintaining ibrutinib while emavusertib will be added for resistance reversal. A brief gap of ibrutinib therapy of <3 weeks is acceptable.

Open to people ages 18 years and up
- Males and females greater than or equal to 18 years of age
- Life expectancy of at least 3 months
- Eastern Cooperative Oncology Group (ECOG) Performance Status of ≤ 1
- For Part A1: Diagnosis of histopathologically confirmed B-cell hematological malignancy (as per the World Health Organization [WHO] 2016 classification; Swedow 2016); eligible subtypes include follicular lymphoma, MZL, DLBCL, mantle cell lymphoma, and WM/LPL without the urgent need for treatment hyperviscosity.
For Part A2: Diagnosis of histopathologically confirmed B-cell NHL, as per the WHO 2016 classification (Swerdlow et al. 2016). Eligible NHL subtypes include follicular lymphoma, MZL, mantle cell lymphoma, DLBCL(including extranodal lymphomas of leg-, testicular-, or NOS type), and primary or secondary CNS lymphoma.
For Part B: Diagnosis of histopathologically confirmed B-cell NHLs, including applicable confirmation as per the WHO 2016 classification (Swerdlow et al. 2016):
- Cohort 1: Marginal zone lymphoma
- Cohort 2: ABC-DLBCL, or extranodal subtypes: Leg-, testicular-, or NOS-type. The population will be enriched for MYD88 L265P mutations. As this occurs more frequently in the ABC-DLBCL(activated B-cell (Hans et al. 2004) subtype, all patients with this subtype qualify for enrollment. If the MYD88 mutation status is unknown at baseline, the lymphoma will be tested for MYD88 mutations.
- Cohort 3: Primary CNS Lymphoma (PCNSL) only. If the MYD88 mutation status is unknown at baseline, the lymphoma will be tested for MYD88 mutations.
- Cohort 4: Patients receiving ibrutinib monotherapy who have developed adaptive, secondary resistance. Indications include:
- MCL, MZL
- Indications for which ibrutinib is NCCN-listed (e.g., PCNSL)
- Patients with NHL and known myddosome mutations
- Patients may be candidates for maintaining ibrutinib while emavusertib will be added for resistance reversal. A brief gap of ibrutinib therapy of <3 weeks is acceptable.
