Full Description

This study is an open-label, multicenter, 2-part study of 1A46 in adult patients with advanced relapsed/refractory (r/r) CD20 and/or CD19 positive B-cell non-Hodgkin lymphoma (NHL) and B-cell acute lymphoblastic leukemia (ALL) who do not have effective standard treatment available. This FIH study will include a dose escalation part and a dose expansion part in 4 cohorts.

Eligibility Criteria

Inclusion Criteria:

Dose Escalation Part:

Aggressive NHL Patients:

Aggressive NHL including mantle cell lymphoma and DLBCL histologies, NOS and/or BCL2, BCL6, and or MY B-cell lymphoma with intermediate features between DLBCL, FL grade 3B, and aggressive B-cell lymphoma unclassifiable
have previously R-CHOP, R-EPOCH or equivalent anti-CD20 containing therapy
with ≥ 2 prior lines of systemic therapy
received or ineligible for autologous stem cell transplant (ASCT)
have received or been intolerant of all other standard therapies thought to confer clinical benefit.

Indolent NHL Patients:

including FL of Grades 1-3A and marginal zone lymphoma (MZL)
refractory or relapsed after ≥ 2 prior lines of systemic therapy who have received or been intolerant of all other standard therapies thought to confer clinical benefit.
Patients must require systemic therapy based on disease-specific criteria.

NHL patients should meet the following requirements:

The following considerations pertain to prior treatment regimens for NHL:

Preinduction salvage chemotherapy and ASCT should be considered 1 therapy.
Patients with gastric extranodal MZL, should have failed H. pylori eradication therapy (when H. pylori positive).
NHL patients must have expression of CD20 and/or CD19-expression
NHL patients in the dose escalation part of the study must have ≥ 1 measurable target lesion as defined by Lugano 2014 criteria ALL Patients:

Ph-positive or Ph-negative B-cell ALL refractory to or relapsed after frontline treatment and 1 salvage regimen, have received or been intolerant of all other standard therapies thought to confer clinical benefit. ALL patients should meet the following requirements:

Relapsed after or not a candidate for allogeneic SCT.
No active acute or chronic graft-versus-host disease for 2 months prior to enrollment and currently receiving no immunosuppressive therapy.
persistent CD19 staining of ≥ 50% of blasts.

Exclusion Criteria:

Patient has brain metastasis or other significant neurological conditions.
Female patients who are lactating and breastfeeding or have a positive serum pregnancy test during the screening period.
Active serious infection requiring antibiotics within 14 days before study entry.

Treatment with corticosteroids (> 10 mg daily prednisone or equivalent) or immunosuppressive medication ≤ 7 days before the first dose of 1A46, with the following exceptions:

Topical, ocular, intra-articular, intranasal, or inhalational corticosteroids.
Dexamethasone used to reduce peripheral blast counts in ALL patients.
Active hepatitis B or C.
Known human immunodeficiency virus (HIV) infection.

Major surgery < 4 weeks or minor surgery < 2 weeks prior to screening.
Live virus vaccines < 30 days prior to screening.
Inflammatory chronic diseases, or any other diseases the investigator considers can be exacerbated in the setting of immune activation.
History of Grade 3-4 allergic reaction to treatment with another mAb, or known to be allergic to protein drugs or recombinant proteins or excipients in 1A46 drug formulation.
Active infection with coronavirus disease 2019 (COVID-19). Patients who have quarantined and have a negative test for virus may enroll.
Concurrent malignancy < 5 years prior to entry other than adequately treated cervical carcinoma in situ, localized squamous cell cancer of the skin, basal cell carcinoma, localized prostate cancer, ductal carcinoma in situ of the breast, or < T1 urothelial carcinoma.
History of Grade 3-4 immune-related adverse events (irAEs) or irAEs requiring discontinuation of prior therapies.
Pleural effusion, pericardial effusion or ascites requiring frequent drainage or medical intervention.
QTc > 480 msec using Fredericia's QT correction formula
Patients in the dose escalation part who weigh < 40 kg.
