About this study
Official title: A Phase II, Open Label, Multicenter Trial of Venetoclax (ABT-199/GDC-0199) as Single Agent in Patients With Relapsed/Refractory BCL-2 Positive Peripheral T Cell Lymphoma Not Otherwise Specified (PTCL-NOS), Angioimmunoblastic T-cell Lymphoma (AITL) and Other Nodal T-cell Lymphomas of T-follicular Helper Origin (TFH)
The FIL_VERT study is a phase II, open label, multicenter clinical trial. The primary of objective of the Study is to evaluate the efficacy of Venetoclax ABT-199/GDC-0199) in terms of overall response rate (ORR) in patients with relapsed/refractory BCL-2 positive peripheral T cell lymphoma not otherwise specified (PTCL-NOS), angioimmunoblastic T-cell lymphoma (AITL) and other nodal T-cell lymphomas of T-follicular helper origin (TFH)
Read the detailed description
This is an open-label, multi-center, single arm phase II trial, with a two-stage design, to evaluate the activity and safety of ABT-199 single agent in patients with BCL-2 pos R/R PTCL-NOS, AITL, TFH.
A pre-screening evaluation of immunohistochemical positivity of BCL-2 will be performed in the relapse biopsy, if available, or otherwise in the initial biopsy. BCL-2 evaluation will be centralized (FIL Laboratories). Only patients with a percentage of BCL-2 positive tumor cells ≥ 25% will be included onto the study. Patients will receive ABT-199 until disease progression, unacceptable toxicity, withdrawal of consent and/or the investigator determines that further therapy is not in the patient's best interest. The primary objective of the study is ORR which will be evaluated after 3 cycles of treatment.
ABT-199 will be administered orally at the dose of 800 mg once daily. Patients will receive ABT-199 until disease progression, unacceptable toxicity, withdrawal of consent and/or the investigator determines that further therapy is not in the patient's best interest (e.g., due to non-compliance, toxicity...) Response evaluation will be performed initially after 3 cycles from the beginning of treatment with ABT-199 (Response Assessment 1) and then every 3 cycles during the first 12 cycles, every 4 cycles from cycle 13 to 24; for those patients still on therapy after 24 cycles, the response evaluation, after this time, will be performed every 6 cycles.
Response will be evaluated according to the Lugano 2014 classification.
TLS is an important identified risk for ABT-199 in oncology studies, especially in CLL. Since there are no available data on the risk of TLS in PTCL, the risk of TLS development should be closely monitored during the study.
TLS prophylaxis includes:
- ABT-199 will be administered according the following ramp up:
- week 1 day 1: 20 mg
- week 1 day 2-3: 50 mg
- week 1 day 4-7: 100 mg
- week 2: 200 mg
- week 3: 400 mg
- week 4 and following: 800 mg
- Hospitalization and monitoring of the subject should occur for a minimum of 72 hours after the initial dose. Discharge of the subject is dependent upon review of chemistry labs 72 hours after the first dose of ABT-199
- IV hydration (150 cc/hr, as tolerable) must be started upon admission and continued during hospitalization at least for 72 hours after the initial dose of ABT-199. Urine output must be monitored
- Allopurinol 300 mg daily to be initiated 3 days before treatment and continued for up to 5 weeks based on the ongoing risk of TLS development. Subjects allergic to allopurinol must use another anti-hypeuricemic drug. Consider use of rasburicase if subjects baseline uric acid level is elevated
- The investigator decision to proceed with ABT-199 treatment initiation and subsequent ramp up will be after having evaluated the normal value of the following biochemistry (potassium, uric acid, phosphorus, calcium and creatinine).
Biohemistry labs (potassium, uric acid, phosphorus, calcium and creatinine) must be performed as follow:
- week 1 (ABT-199 dose from 20 to 100 mg/daily): at timepoints 0 (pre-dose, within 4 hours from ABT-199 administration), 6-8, 24, 48, 72, 96 hours after the first dose of ABT-199. Day 2 dose should not be administered until the 24 hours post-dose labs are reviewed by the investigator;
- week 2 (ABT-199 dose 200 mg/daily): at timepoints 0 (pre-dose, with-in 4 hours from ABT-199 administration), 6-8, 24 hours after. Day 2 dose should not be administered until the 24 hours post-dose labs are reviewed by the investigator;
- week 3 (ABT-199 dose 400 mg/daily): at timepoints 0 (pre-dose, with-in 4 hours from ABT-199 administration), 6-8, 24 hours after. Day 2 dose should not be administered until the 24 hours post-dose labs are reviewed by the investigator;
- week 4 (ABT-199 dose 800 mg/daily): at timepoints 0 (pre-dose, with-in 4 hours from ABT-199 administration), 6-8, 24 hours after. Day 2 dose should not be administered until the 24 hours post-dose labs are reviewed by the investigator Nephrology (or other acute dialysis service) must be consulted/contacted on admission (per institutional standards to ensure emergency dialysis is available).
The efficacy interim analysis will be performed after enrollment of 18 patients. It is to be planned a stop in recruitment of at least 3 months to have the results of response assessment. The primary efficacy analysis will consist of an estimate of ORR on the efficacy population after the first 3 cycles of therapy, with 90% confidence intervals (according to 1-sided alpha error of 0.05). To proceed to the second stage, the minimum number of patients with an ORR is 3/18.

What is being measured
The primary outcome is the main question the study is designed to answer.
Overall response rate (ORR)
Overall response rate (ORR) will be defined as the proportion of patient in CR or PR according to Re-sponse Criteria (Lugano 2014) after the first 3 cycles. Efficacy will be assessed after the first 3 cycles or, in case of discontinuation, at the EoT visit. Patients without response assessment (due to whatever reason) will be considered as non-responders.
Measured: After the first 3 cycles (each cycle is 28 days)
Secondary outcomes (9)
Complete remission (CR)
CR rate will be defined according to Lugano criteria21 after the first 3 cycles and at each restaging. The best overall response will be defined as the best response between the date of begin-ning of therapy and the last restaging. Patients without response assessment (due to whatever rea-son) will be considered as non-responders
Measured: After the first 3 cycles (each cycle is 28 days)
Partial response (PR)
PR rate will be defined according to Lugano criteria21 after the first 3 cycles and at each restaging. The best overall response will be defined as the best response between the date of begin-ning of therapy and the last restaging. Patients without response assessment (due to whatever rea-son) will be considered as non-responders.
Measured: After the first 3 cycles (each cycle is 28 days)
Stable Desease (SD)
SD rate will be defined according to Lugano criteria21 after the first 3 cycles and at each restaging. The best overall response will be defined as the best response between the date of begin-ning of therapy and the last restaging. Patients without response assessment (due to whatever rea-son) will be considered as non-responders.
Measured: After the first 3 cycles (each cycle is 28 days)
Time To Response (TTR)
TTR will be defined for all patients who achieved a response (CR or PR) and is measured from the date of beginning of therapy until the date of response. Patients in relapse or progression will be cen-sored at their last assessment date. Patients death due to any cause will be consider censored or competing event according to different analysis plan
Measured: 1 year from the date of the first dose
Duration of Remission (DoR)
DoR will be defined for all patients who achieved a response (CR or PR) and it is measured from the time of response until the date of progression or relapse. Patients without relapse or progression will be censored at their last assessment date; Patients death due to any cause will be consider censored or competing event according to different analysis plan;
Measured: 6 months from the first 3 cycles (each cycle is 28 days)
Progression free Sruvival (PFS)
PFS will be defined as the time from beginning of therapy until lymphoma relapse or progression or death as a result of any cause; responding patients and patients who are lost to follow up will be cen-sored at their last assessment date;
Measured: 1 year from the date of the first dose
Overall Survival (OS)
OS will be defined as the time from beginning of therapy until death as a result of any cause; patients alive will be censored at their last assessment date;
Measured: 1 year from the date of the first dose
Duration of treatment (DoT)

Interventions
| Intervention | Type | Arms |
|---|---|---|
| VenetoclaxAlso: ABT-199/GDC-0199Venetoclax (ABT-199) will be administered orally (800 mg daily). Patients will receive ABT-199 until disease progression, unacceptable toxicity, withdrawal of consent and/or the investigator determines that further therapy is not in the patient's best interest. Tumor Lysis Syndrome (TLS) is an important identified risk for Venetoclax in oncology studies. Since there are no available data on the risk of TLS in PTCL, the risk of TLS development should be closely monitored during the study. to avoid TLS ABT-199 will be administered according the following ramp up: W eek 1 day 1: 20 mg W 1 day 2-3: 50 mg W 1 day 4-7: 100 mg W 2: 200 mg W 3: 400 mg W 4 and following: 800 mg | Drug | ARM1 - Venetoclax (ABT-199) |
Primary outcome
Overall response rate (ORR)
Time frame: After the first 3 cycles (each cycle is 28 days)
Overall response rate (ORR) will be defined as the proportion of patient in CR or PR according to Re-sponse Criteria (Lugano 2014) after the first 3 cycles. Efficacy will be assessed after the first 3 cycles or, in case of discontinuation, at the EoT visit. Patients without response assessment (due to whatever reason) will be considered as non-responders.
9 secondary outcomes
Complete remission (CR)
Time frame: After the first 3 cycles (each cycle is 28 days)
Partial response (PR)
Time frame: After the first 3 cycles (each cycle is 28 days)
Stable Desease (SD)
Time frame: After the first 3 cycles (each cycle is 28 days)
Time To Response (TTR)
Time frame: 1 year from the date of the first dose
Duration of Remission (DoR)
Time frame: 6 months from the first 3 cycles (each cycle is 28 days)
Progression free Sruvival (PFS)
Time frame: 1 year from the date of the first dose
Overall Survival (OS)
Time frame: 1 year from the date of the first dose
Duration of treatment (DoT)
Time frame: 1 year from the date of the first dose
Toxicity - Incidence of Adverse Events
Time frame: Through study completion, up to 30 months
Results and safety
The study was stopped early (reason given: efficacy lower than expected). Results are not available in the source record.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Venetoclax in people with T-Cell Lymphoma Relapsed and T-Cell Lymphoma Refractory, run by Fondazione Italiana Linfomi - ETS at 13 sites in Italy.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 26 inclusion and 28 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 12 Dec 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 13 sites in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was stopped early (reason given: efficacy lower than expected). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Overall response rate (ORR) (time frame: After the first 3 cycles (each cycle is 28 days)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03552692, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Dec 2023.
