Loncastuximab Tesirine and Venetoclax for Relapsed/ Refractory Non-Hodgkin Lymphoma
Study Details
Study Description
Brief Summary
The purpose of this study is to determine the correct dose and safety of combining two new cancer drugs, loncastuximab tesirine and venetoclax, as a treatment for relapsed or refractory B cell lymphoma.These drugs are used to treat some lymphomas, but have not yet been tested in combination for the treatment of lymphoma. The main goal of this study is to determine the safety of the combination.

Phase 1 |
Detailed Description
This is a phase I trial designed to evaluate the safety and tolerability of loncastuximab tesirine given in combination with venetoclax for treatment of relapsed/refractory non - Hodgkin lymphoma.
Loncastuximab tesirine is an investigational (experimental) drug that works by targeting a protein in cancer cells (called CD19) and delivering a small amount of chemotherapy directly to the cancer cells. Loncastuximab tesirine is experimental because it is not approved by the Food and Drug Administration (FDA). Venetoclax, is a targeted anti-cancer drug, which works by imitating a particular protein produced by the tumor and interrupting its normal processes, ultimately causing the tumor cells to die. Adding venetoclax to the loncastuximab tesirine regimen is believed to increase the chance of getting relapsed or refractory B cell lymphoma cancer in remission. Venetoclax is approved by the FDA for treatment in some types of cancer, but is not approved by the FDA for the treatment of lymphoma soit is considered experimental in this study. Up to 36 subjects will take in this phase I research study.
The primary objective for this study: To determine the safety and tolerability of the combination of loncastuximab tesirine and venetoclax to identify the recommended phase 2 dose (RP2D) of these agents.
Secondary objectives are:
-
To describe the adverse event profile of the combination of loncastuximab tesirine and venetoclax.
-
To describe the overall response rate (ORR) and complete response rate (CRR) of relapsed/refractory non-Hodgkin lymphoma treated with the combination of loncastuximab tesirine and venetoclax.
-
To describe the overall survival (OS) and progression free survival (PFS) of subjects with relapsed / refractory non-Hodgkin lymphoma treated with the combination of loncastuximab tesirine and venetoclax.
-
To describe the disease-free survival, the disease specific survival and time to treatment failure of subjects with relapsed/refractory non-Hodgkin lymphoma treated with the combination of loncastuximab tesirine and venetoclax.

Loncastuximab tesirine 50 - 150 μg/kg will be administered as a 30 minutes IV infusion on Day 1 of each cycle for 6 cycles. On doses over 100 μg/kg, subsequent dosing (i.e. beyond 100 μg/kg) will be done at 50% of the dose that is administered on the first 2 cycles.
Other Names:
Drug: Venetoclax
Participants will receive venetoclax at target doses of 400 - 800mg orally on days 1 - 5 of each (21 day) cycle.
On cycle 1, venetoclax dose will be escalated to reach the target dose over the course of 5 days for target dose 400mg, 6 days for target dose 600mg and 7 days for target dose 800mg
Venetoclax should preferably be given after a meal and on cycle 1 should be preceded by prophylaxis for tumor lysis syndrome (TLS).

- Overall survival (OS) [At end of follow-up (1 year)]
OS is defined as the time from the date of study entry to the date of death, with censoring done on live patients at the time of last follow up. OS will be estimated using the Kaplan Meier method
- Progression free survival (PFS) [At end of follow-up (1 year)]
PFS is defined as the time from entry onto study until lymphoma progression or death from any cause. PFS will be estimated using the Kaplan Meier method The precise date of progression is generally unknown. It may be defined as the first date of documentation of a new lesion or enlargement of a previous lesion, or the date of the scheduled clinic visit immediately after radiologic assessment has been completed. Where there is missing information, censoring of the data may be defined as the last date at which progression status was adequately assessed or the first date of unscheduled new anti-lymphoma treatment.
- Median disease-free survival [At end of follow-up (1 year)]
Disease-free survival is measured from the time of occurrence of disease-free state (e.g. the adjuvant setting following surgery or radiation therapy) or attainment of a complete remission) to disease recurrence or death from lymphoma or acute toxicity of treatment.
- Median disease-specific survival [At end of follow-up (1 year)]
Disease-specific survival is defined as death from lymphoma, or from toxicity from the drug. Death from unknown causes should be attributed to the drug
- Time-to-treatment failure [At end of follow-up (1 year)]
Time to treatment failure (event-free survival) is measured from the time from study entry to any treatment failure including discontinuation of treatment for any reason, such as disease progression, toxicity, patient preference, initiation of new treatment without documented progression, or death.

TTP as measured by median time in months from treatment to death or relapse
- Partial response rate (PRR) [At end of follow-up (1 year)]

-
A woman is considered to be of childbearing potential if she is postmenarcheal, has not reached a postmenopausal state (< 12 continuous months of amenorrhea with no identified cause other than menopause), and has not undergone surgical sterilization (removal of ovaries and/or uterus).
Examples of contraceptive methods with a failure rate of < 1% per year include bilateral tubal ligation, male sterilization, hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine devices, and copper intrauterine devices.
The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception.
-For men: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures, and agreement to refrain from donating sperm, as defined below:
--With female partners of childbearing potential, men must remain abstinent or use a condom plus an additional contraceptive method that together result in a failure rate of < 1% per year during the treatment period and for at least 6 months after the last dose of loncastuximab. Men must refrain from donating sperm during this same period.
With pregnant female partners, men must remain abstinent or use a condom during the treatment period and for at least 6 months after the last dose of loncastuximab to avoid exposing the embryo.
The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception.
