About this study

Official title: A Phase II, Open Label, Multicenter Trial of Daratumumab in Combination With Gemcitabine, Dexamethasone and Cisplatin (D-GDP) in Patients With Relapsed/Refractory CD38 Positive Peripheral T-cell Lymphoma Not Otherwise Specified (PTCL-NOS), Angioimmunoblastic T-cell Lymphoma (AITL) and Other Nodal Lymphomas of TFH Cell Origin

FIL_Dara-GDP is a phase II, open label, multicenter clinical trial. The sponsor of this clinical trial is Fondazione Italiana Linfomi (FIL). The primary objective is to evaluate the efficacy of 4 courses of D-GDP (Daratumumab in combination with Gemcitabine, Cisplatin, Dexamethasone) in terms of complete response in patients with peripheral T-cell lymphoma not otherwise specified (PTCL-NOS), angioimmunoblastic T-cell lymphoma (AITL) and other nodal lymphomas of T follicular helper cells (TFH cells) origin refractory/relapsed after at least one and no more than two previous lines of therapy.

Read the detailed description

This is an open-label, multicenter, single arm, single-stage phase II trial. After the patient signs the written informed consent the patient will enter the screening phase planning baseline assessments and a concomitant upfront confirmation of diagnosis of Peripheral T-Cell Lymphoma Not Otherwise Specified (PTCL-NOS), Angioimmunoblastic T-cell lymphoma (AITL) or Nodal Lymphoma of T Follicular Helper cells (TFH cells) origin and a central evaluation of immunohistochemical positivity of CD38 (cluster of differentiation 38) on bioptic material used to perform local diagnosis of relapsed disease, or that used for the more recent biopsy in the case of refractory patients. A core needle biopsy is considered sufficient for review and CD38 evaluation. Evaluation at central laboratory can be performed in bone marrow sections in those patients with only bone marrow lymphoma infiltration.

Only patients with confirmed eligible diagnosis and a percentage of CD38 positive tumor cells ≥ 5% will be considered eligible for study treatment.

The treatment consists of an induction phase and a maintenance phase.

Induction phase:

4-6 courses (according to response after cycle 4 and to patient compliance) of D-GDP (Daratumumab in combination with Gemcitabine, Cisplatin, Dexamethasone) every 21 days pursuant to the following schedule:

  • Daratumumab cycle 1: 8 mg/kg i.v. on day 2 and on day 9; cycle 2-6: 16 mg/kg i.v. on day 2 and day 9)
  • Gemcitabine 1000 mg/sm i.v. day 1 and day 8 (gemcitabine on day 8 to be skipped in case of grade 3-4 toxicity)
  • Cisplatin 75 mg/sm i.v. day 1
  • Dexamethasone 40 mg i.v. or po days 1-2-3-4-9
  • Granulocyte-colony stimulating factor (G-CSF) from day 3 to 6, and from day 10 to 13 (to be prolonged if necessary) After 4 courses of D-GDP (Daratumumab in combination with Gemcitabine, Cisplatin, Dexamethasone), patients in Complete Remission/Partial Remission (CR/PR) and eligible for allogeneic stem cell transplantation (allo-SCT) will be addressed to allo-SCT consolidation.

Otherwise, patients in Complete Remission (CR) will enter the maintenance phase at this point of the study.

Patients in Partial Remission (PR) (not eligible for allogeneic stem cell transplantation) or in Stable Disease (SD) after D-GDP x 4 cycles can receive 2 additional courses of D-GDP before maintenance or can move directly to maintenance, according to center choice (based on patient condition, performance status and quality of response).

Patients who respond (Complete Remission/Partial Remission) after 6 courses of induction phase (end of induction, EOI) and eligible to allogeneic stem cell transplantation (allo-SCT) will be addressed to allo-SCT consolidation.

Patients who respond to the induction phase (Complete Remission/Partial Remission) and are not eligible for allogeneic stem cell transplantation (allo-SCT) and patients in stable disease (SD) at the End Of Induction (EOI), will move to the maintenance phase.

Patients in Progressive disease (PD) at any time will discontinue treatment, as well as patients experiencing at any time unacceptable toxicity.

Maintenance phase:

starting 28 days after the beginning of cycle 4 or 6 (or, in case of toxicity grade > 1, after toxicity is resolved) and up to 24 cycles from start of D-GDP (Daratumumab in combination with Gemcitabine, Cisplatin, Dexamethasone) according to the following schedule:

  • Daratumumab 16 mg/kg single administration every 28 days

Treatment with D-GDP (Daratumumab in combination with Gemcitabine, Cisplatin, Dexamethasone) or daratumumab single agent will be discontinued before completion of 24 cycles in case of:

  • decision of the investigator to consolidate D-GDP (Daratumumab in combination with Gemcitabine, Cisplatin, Dexamethasone) response with allogeneic stem cell transplant
  • disease progression
  • unacceptable toxicity
  • withdrawal of consent
  • investigator determines that further therapy is not in the patient's best interest (e.g., due to non-compliance, toxicity, etc.) Adverse events ("Common Terminology Criteria for Adverse Events", CTCAE v. 5.0) will be monitored from the first study-related procedure, throughout treatment, maintenance and for 30 days after the end of treatment with the study drug.

Safety monitoring and stopping rules:

In order to monitor the safety and the activity of the treatment in small cohorts of patients, the Bayesian approach of Thall et al. (1995), as extended by Thall and Sung (1998) will be used.

Monitoring of relevant toxicity after 4 cycles of D-GDP (Daratumumab in combination with Gemcitabine, Cisplatin, Dexamethasone) will be done to ensure that it is not higher than an acceptable toxicity of 30% (as defined in the safety endpoints) and the monitoring of activity after 4 cycles of D-GDP (Daratumumab in combination with Gemcitabine, Cisplatin, Dexamethasone) will be done to ensure that Complete Remission (CR) proportion is not lower than 40%.

The prior probability of toxicity and activity are modeled by beta distributions [Beta (0.6,1.4) and Beta (0.8,1.2), respectively].

The enrolment will be stopped if the posterior probability of the treatment being more toxic or less active than expected is greater than 95%.

The primary efficacy analysis will be performed after enrolment of 35 patients. The primary efficacy analysis will consist of an estimate of Complete Remission Rate (CRR) on the efficacy population after 4 cycles of D-GDP (Daratumumab in combination with Gemcitabine, Cisplatin, Dexamethasone) therapy, with 90% confidence intervals (according to 1-sided alpha error of 0.05). To conclude that the new treatment is promising, the minimum number of patients with a Complete Remission (CR) is 12/35.

The time-to-event functions (Overall Survival (OS) and Progression Free Survival (PFS)) will be estimated by the Kaplan-Meier product-limit method.

Subgroup analyses on primary efficacy parameter (Complete Remission Rate (CRR)) will be performed to assess the role of daratumumab maintenance and to explore potential prognostic role of CD38 expression. A logistic regression model will be used and the effect (Complete Remission Rate (CRR)) and its 95% Interval of Confidence (CI) will be presented.

For safety analysis, both at patient level and at therapy cycle level, summaries of incidence rates (frequencies and percentages) and intensity of individual adverse events by CTCAE (Common Terminology Criteria for Adverse Events (CTCAE)) v. 5.0 will be reported.

The results of this study will support the rationale of a phase III randomized trial if both efficacy and safety endpoints will be considered promising.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Complete Response Rate (CRR)

    The Complete Response Rate is defined as the percentage of patient in Complete Remission (according to Lugano classification response Criteria). It will be assessed after the first 4 cycles of D-GDP chemotherapy. In case of early discontinuation, efficacy will be assessed at the End Of Treatment (EOT) visit. Patients without response assessment (due to whatever reason) will be considered as non-responders. CR: complete radiological response, no extralymphatic sites, no new lesions, organ enlargement regress to normal and normal morphology of bone marrow; PR: >=50% decrease of sum of the product of perpendicular diameter of up to 6 dominant, measurable nodes and and extranodal sites.

    Measured: the endpoint will be assessed from the start date of therapy to the end of the first four cycles of therapy (cycles of 21 days).

Secondary outcomes (4)
  1. Overall Response Rate (ORR)

    Overall Response Rate is defined as the percentage of patients in complete remission or in partial remission (according to the Lugano 2014 criteria) after the first 4 cycles of therapy (cycles of 21 days). Patients without response assessment (due to whatever reason) will be considered as non-responders. CR: complete radiological response, no extralymphatic sites, no new lesions, organ enlargement regress to normal and normal morphology of bone marrow; PR: >=50% decrease of sum of the product of perpendicular diameter of up to 6 dominant, measurable nodes and and extranodal sites.

    Measured: the endpoint will be assessed from the start date of therapy to the end of the first four cycles of therapy (cycles of 21 days) and at each restaging

  2. Overall Survival (OS)

    Overall Survival, the percentage of patients alive, is defined from the start date of therapy to the date of death from any cause. Patients alive and those who are lost to follow-up at the time of the final analysis will be censored at the date of the last contact.

    Measured: The end point will be assessed from the start date of therapy up to 3 months.

  3. Progression-Free Survival (PFS)

    The length of time during and after the treatment that patients live with the disease, but it does not get worse. Progression-Free Survival (PFS) will be defined from the date of starting therapy and the date of disease progression, relapse or death from any cause.

    Responding patients, according to the Lugano classification response Criteria, and patients who are lost to follow-up will be censored at their last assessment date.

    Measured: The endpoint will be assessed from the start date of therapy up to 3 months.

  4. Toxicity - Frequency of Relevant Toxicities

    Frequency of relevant toxicities. Toxicities will be classified according to Common Terminology Criteria for Adverse Events (CTCAE), version 5.0. This endpoint will be evaluated from the start date of therapy and at any time during therapy and follow-up.

    Measured: the endpoint was assessed after 26 months from the date of starting therapy in place of the planned 42 months, due the early interruption of the study

Model description
Prospective, multicenter, single arm, single-stage phase II trial in patients with refractory/relapsed CD38 positive PTCL-NOS, AITL and TFH with centrally assessed CD38 expression ≥ 5%. It is expected for the current trial that D-GDP will improve the CR rate to 40% with an absolute improvement of 20%, while the toxicity rate is maintained at 30%. Sample size: A'Hern's Single-Stage Phase II design will be used. The sample size was calculated according to the primary efficacy endpoint. Based on literature, the null hypothesis that the true proportion of CR after four courses of D-GDP is 0.20 will be tested against an alternative CR proportion of 0.40 with an absolute improvement of 0.20, considered clinically promising with the experimental treatment. Assuming a type I error rate of 5% and a power of 80% when the CR proportion is 40% overall 35 patients will be accrued. The null hypothesis will be rejected if 12 or more CR out of 35 patients are observed after four courses of D-GDP.

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 20 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 28 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 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?

Yes. Results are posted in the registry (first posted 28 Mar 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Complete Response Rate (CRR) (time frame: the endpoint will be assessed from the start date of therapy to the end of the first four cycles of therapy (cycles of 21 days).). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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?
