About
This is an investigator-initiated industry-supported phase 1 clinical trial conducted in the phase 1 clinic at The University of Texas MD Anderson Cancer Center who will hold the Investigational New Drug (IND). Lvygen Biopharma will provide as investigational supply LVGN3616, LVGN6051 and LVGN7409 at no cost to the patients on this study. This study will explore antitumor activity of four LVGN3616 and LVGN6051 based regimens in seven selected tumor types:
Full description
Primary Objectives:

- To evaluate antitumor activity of LVGN3616 and LVGN6051 ± LVGN7409 in combination with nab-paclitaxel or bevacizumab and cyclophosphamide (16 specific cohorts according to disease type and regimen).

Patients must have histologically confirmed metastatic solid tumors with pre-identified molecular profiling in a Clinical Laboratory Improvement Amendments (CLIA)-certified laboratory, either refractory to standard therapy or for which no effective standard therapy that increases survival for at least 3 months is available, or they declined standard of care therapy (the treating physician needs document reasons for a patient to decline standard of care therapy and provide justification for participating this study in the medical record, which will be recorded in eCRF).

Women of child-bearing potential (WOCBP) must have a negative serum pregnancy test within 3 days prior to initiation of therapy (C1D1) and must agree to use effective birth control during the study prior to the first dose and for at least 6 months after the last dose. Female patients are not considered to be of child-bearing potential if they are post-menopausal (no menses for 12 months without an alternative medical cause) or permanently sterile (hysterectomy, bilateral salpingectomy, or bilateral oophorectomy).

For remote and In-person consenting, we will follow the Office of Clinical Research SOP:04 Informed Consent Process.
-

-
Fridericia's corrected QT interval (QTcF =QT/∛(60/HR) ) ≤ 460 milliseconds (ms) for males and ≤ 480 ms for females on ECG conducted at rest during Screening.
Note: Patients with an atrioventricular pacemaker or other condition (for example, right bundle branch block) that renders the QT measurement invalid are an exception and this criterion does not apply.
- Agreeing to provide an archival tissue block, or 10 formalin-fixed paraffin-embedded (FFPE) slides if available.
- Prior treatment with immunotherapy, taxane, VEGF inhibition or cyclophosphamide is allowed. However, prior immunotherapy with anti-PD1/PD-L1 plus a CD137 agonist or a CD40 agonist is not allowed.
Exclusion criteria
Patients who meet any of the following criteria will be not eligible for the study:
-
Any treatment specifically for systemic tumor control given within 3 weeks before the initiation of therapy; within 2 weeks if cytotoxic agents were given weekly, within 6 weeks for nitrosoureas or mitomycin C; within 5 half-lives for targeted agents with half-lives and pharmacodynamic effects lasting < 5 days; or failure to recover from toxic effects of any previous therapy.
