Study of TJ011133 in Participants With Relapsed/ Refractory Advanced Solid Tumors and Lymphoma

Overview

About this study

The purpose of this study is to assess the safety and tolerability of TJ011133 in participants with solid tumors and lymphoma.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria: 

Part 1 Dose Escalation:

  • Histological or cytological diagnosis of solid tumor or Hodgkin’s Lymphoma who have relapsed or progressed and who are ineligible for all therapies with demonstrated clinical benefit.
    • Note: there is no limit to the number of prior treatment regimens; or
  • Relapsed/refractory CD20 positive, B-cell NHL who have progressed following at least 2 prior systemic therapies. For aggressive histologies, frontline treatment must have included an alkylating agent; or
  • Relapsed/refractory classical Hodgkin’s Lymphoma who have progressed following at least 2 prior systemic therapies and have progressed on checkpoint inhibitors (for Part 1B only);
  • In Part 1A (45 mg/kg dose cohort only), Part 1B or Part 1C, archival tumor tissue and fresh post-treatment tumor biopsy obtained that allows preparation of the number of slides required in the separate study-specific specimen preparation instructions. Samples will be collected, processed and stored according to a separate laboratory manual.

Part 2 Dose Expansion for Combination Therapy with Rituximab:

  • Relapsed/refractory DLBCL including histologically confirmed de novo (NOS) or transformed DLBCL (including transformation from follicular lymphoma of any grade, gastric MALT lymphoma and non-gastric MALT lymphoma) expressing CD20 by IHC (immunohistochemistry) or flow cytometry, primary mediastinal large B‐cell lymphoma, or T‐cell rich large B cell lymphoma, which are relapsed after at least 2 prior lines of systemic therapy including at least one rituximab-containing regimen or refractory disease to rituximab without better available choices.
  • Confirmed marginal zone or follicular lymphoma (Grade 1-3a) expressing CD20+ by IHC or flow cytometry, relapsed after at least 2 prior line of systemic therapy including at least one rituximab-chemotherapy combination regimen or refractory to rituximab-containing regimen without better available choices; for indolent NHL histology, progression following prior treatment with an alkylating agent is allowed but not required.
    • NOTE: Refractory disease is defined as progression within 6 months of last dose of therapy. Relapsed disease is defined as disease recurrence or PD following a response after more than 6 months after last dose. Patients who received CAR-T therapy are allowed but cannot have progressive disease within 3 months of CAR-T therapy.
    • At least one measurable lesion as defined by Lugano criteria (version 2014).
    • Available fresh metastatic biopsy sample prior to study entry and one mandatory on-treatment tumor biopsy in US clinical sites, unless there is difficulty obtaining the sample (e.g., hard to reach tumors or biopsies requiring surgical intervention). Waiver of biopsy samples must be discussed with the medical monitor. Tumor biopsy samples collected should allow for sample preparation as detailed in the separate study-specific specimen preparation instructions. Mandatory archival pre-treatment or optional ontreatment FFPE tumor tissue that allow for sample preparation as detailed in the separate study-specific specimen preparation instructions will be collected from subjects enrolled at sites in China in the NHL cohort of Part 2.

Part 2 Dose Expansion for Combination Therapy with Pembrolizumab:

  • Locally advanced or metastatic NSCLC that expresses PD-L1 (Tumor Proportion Score (TPS) ≥1%) as determined by an FDA-approved test, with disease progression on or after platinum containing chemotherapy and checkpoint therapy.
  • Patients with NSCLC must have progressed on treatment with one prior PD1/L1 inhibitor administered either as monotherapy or in combination with other checkpoint inhibitors or other therapies.
  • Patients who have had more than 1 prior PD-(L)1 inhibitor may be considered after discussion with the Medical Monitor. PD-1/L1 inhibitor treatment progression is defined by meeting all of the following criteria:
    • has received at least 2 doses of the PD-1/L1 inhibitor (must be an approved PD-1/L1 inhibitor);
    • has been on a continuous regimen of the PD-1/L1 inhibitor for at least 4 months without disease progression;
    • has demonstrated radiographic disease progression after PD-1/L1.
  • Epithelial ovarian cancer, fallopian tube, or primary peritoneal cancer with any high-grade serous component and immune-oncology (IO) treatment naive subjects with metastases progressed on or after platinum-containing therapy and are not eligible for further platinum-containing treatment. Patients must meet the following criteria:
    • platinum-refractory, platinum-resistant disease defined by progression of disease on a platinum-containing regimen or recurrence of disease within 180 days of receiving the last dose of platinum-based treatment;
    • must not have progressed during the first 3 months of first line platinum-based therapy or must not have progressed within 3 months after completing first line platinum-based therapy;
    • must not have evidence of bowel obstruction requiring hospitalization and decompression within the past 30 days;
    • must not have ascites that requires therapeutic paracentesis in the last 30 days;
    • must not have tumors with low malignant potential (ie. borderline tumors) or mucinous tumors.
    • Prior lines of therapy to include:
      • Patients must have had 1 to 3 prior lines of therapy including at least one bevacizumab-containing regimen or ineligible for all other available therapies; Or
      • Patients must be in the 4th or 5th line of treatment, irrespective of bevacizumab or who are ineligible for all therapies with demonstrated clinical benefit; Or
      • Patients with known BRCA-positive associated cancer or mutation, prior therapy must include PARP inhibitors (unless contraindicated)
    • At least one measurable lesion as defined by RECIST 1.1 solid tumors.
    • Available fresh metastatic biopsy sample prior to study entry and one mandatory on-treatment tumor biopsy, unless there is difficulty obtaining the sample (e.g., hard to reach tumors or biopsies requiring surgical intervention). Waiver of biopsy samples must be discussed with the medical monitor. Tumor biopsy samples collected should allow for sample preparation as detailed in the separate study-specific specimen preparation instructions.
