A Study of DPX-Survivac Vaccine Therapy in Patients With Recurrent Survivin-expressing DLBCL

June 16, 2021 updated by: ImmunoVaccine Technologies, Inc. (IMV Inc.)

Phase 2 Study of an Immunotherapeutic Vaccine, DPX-Survivac With Low Dose Cyclophosphamide in Patients With Recurrent Survivin-Expressing Diffuse Large B-Cell Lymphoma (DLBCL)

This phase 2 study was designed to assess the efficacy and safety of DPX-Survivac plus low dose cyclophosphamide in up to 24 subjects with recurrent diffuse large B-cell lymphoma (DLBCL) who are not eligible for transplant. However, with the evolving field of immunotherapy Immunovaccine has begun to focus on combination therapies, combining DPX-Survivac treatment with checkpoint inhibitors and other immune modulators. This phase 2 study was therefore terminated with fewer subjects than planned to allow the progress of other studies, such as NCT03349450.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

A multi-center treatment study assessing the efficacy and safety of an immunotherapeutic vaccine (DPX-Survivac) combined with low dose cyclophosphamide. Subjects with measurable, histologically proven DLBCL expressing survivin will be treated in this open-label, single arm study. Survivin is a protein commonly over-expressed in many types of cancer, including DLBCL.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Genders Eligible for Study

Description

Main Inclusion Criteria:

  • Subjects with histologically proven recurrent DLBCL. Subjects may have recurrence after primary or second treatment regimens for DLBCL. Subjects with recurrence at least 90 days post-autologous stem cell transplantation (ASCT) are eligible. Patients with partial response or measurable disease after first line therapy (who are not candidates for ASCT) or after second line therapy without disease progression may also be eligible.
  • Previous localized surgery, radiotherapy, and chemotherapy more than 21 days prior to SD0.
  • Subjects may have received previous courses of an investigational biologic therapy including active or passive immunotherapy (e.g. rituximab), other B cell depleting antibody therapy, or radioimmunotherapy (e.g. tositumomab or ibritumomab) if last administration is greater than 77 days prior to SD0.
  • Subjects must have at least one measurable site of disease.
  • Willing to undergo a pre-treatment and post-treatment tumor biopsy.
  • Subjects must have evidence of survivin expression in pre-treatment tumor sample.
  • A screening Eastern Cooperative Oncology Group Performance Status (ECOG) of 0-1.
  • A life expectancy > 6 months.

Main Exclusion Criteria:

  • Patients eligible for possible curative therapies such as ASCT.
  • Patients undergoing concurrent chemotherapy, radiation therapy, or immunotherapy or who are currently on an investigational product/trial are excluded. There must be at least 21 days since completion of prior chemotherapy/radiation and at least 77 days since completion of immunotherapy until study treatment begins (SD0). Subjects must have recovered from all acute toxicities from prior treatment; peripheral neuropathy must be < grade 2.
  • Lactate dehydrogenase (LDH) greater than 2 times the upper limit of normal.
  • Patients with refractory disease after their last treatment (i.e. progression within 90 days).
  • Patients who have received prior survivin based vaccines.
  • Progressive CNS lymphoma requiring treatment within 84 days prior to SD0.
  • History of active autoimmune disease, such as but not restricted to, inflammatory bowel disease, systemic lupus erythematosus, ankylosing spondylitis, scleroderma, or multiple sclerosis requiring treatment within the last two years.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
