About this study

Official title: Phase I/II Study of Low-Dose Cyclophosphamide, Tumor Associated Peptide Antigen (TAPA)-Pulsed Dendritic Cell (DC) Therapy and Low Dose GM-CSF, as Consolidation Therapy in Patients With Metastatic Solid Malignancies

This study evaluates the effectiveness of Tumor Associated Peptide Antigens (TAPA) pulsed dendritic cell injections as a potential consolidation therapy for patients with metastatic solid malignancies (SM). The investigators hypothesize that treatment of patients with metastatic SM who demonstrate a tumor response, or whose disease remains stable, after conventional first-line systemic therapy AND who lack an available, potentially curative therapeutic intervention and whose tumor cells and/or blood express at least one (1) TAPA of a defined panel of TAPAs will result in TAPA-specific T-cell responses without significant toxicities. The investigators also hypothesize CD4+ and CD8+ T-cell responses generated against specific TAPAs may translate into clinical antitumor activity.

Read the detailed description

Patients diagnosed with metastatic solid malignancies (SM), who have responded or whose disease remains stable following first line systemic therapy, and without available, potential curative therapeutic options, will be candidates for this Phase I/II study. Potentially eligible patients who agree to participate and sign a consent form will have their neoplastic cells and/or blood analyzed for the expression of a specific panel of Tumor Associated Peptide Antigens (TAPAs), including Sp17, ropporin, AKAP-4, PTTG1, Span-xb, Her-2/neu, HM1.24, NY-ESO-1 and MAGE-1. Patients whose tumors express one (1) or more of these TAPAs will receive three (3) days of subcutaneous Granulocyte Macrophage Colony Stimulating Factor (GM-CSF) to increase bone marrow production of monocytes and dendritic cell (DC) precursors, and whole blood will be obtained by phlebotomy and/or leukapheresis for generation of autologous DCs. Patient's DCs will be generated in Kiromic's Cell Processing Good Manufacturing Process (GMP) facility, according to established Standard Operating Procedures, and activated by pulsing/loading them with the TAPA(s) relevant for each particular patient. Patients will receive five (5) days of low-dose cyclophosphamide prior to each vaccination with TAPA-pulsed DCs to decrease Treg activity. TAPA-pulsed DCs will be administered at a fixed dose of up to 1 X 107 DCs at least two (2) days following cyclophosphamide administration. DC vaccination schedule will be once every fourteen (14) days via subcutaneous (SC) and intradermal (ID) injections for a total of 6 vaccinations. Low dose GM-CSF will also be administered SC for five (5) consecutive days, starting three (3) to six (6) hours after each TAPA-pulsed DC treatment, to optimize immune responses. Patients will be followed on a weekly basis (or more frequently if required) to evaluate treatment-related toxicity. Immune responses and anti-tumor responses will be evaluated per protocol specifications. Continuation and stopping rules for the study will be defined based on toxicity/tolerability (Phase I) and/or immune responses (Phase II).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • TAPA-pulsed DC vaccineBiological

    A cycle of low-dose cyclophosphamide (100mg/day) by mouth for 5 days starting seven 7 days prior to the DC vaccine cycle to reduce Treg activity. Low-dose cyclophosphamide will be taken every 14 days for six 6 cycles. A total of 6 vaccines containing 1 x 10^7 TAPA-pulsed DC will be administered SQ every 14 days. The DC vaccine is given on Day 1 of the DCV cycle plus low-dose GM-CSF 50mcg/day SQ x 5 days (Day 1 to Day 4). GM-CSF is administered for 5 days to increase monocyte production and dendritic cell precursors to optimize immune responses.

TAPA-pulsed DC vaccineExperimentalThe subject will take low-dose cyclophosphamide by mouth for 5 days starting 7 days prior to the vaccine cycle. The vaccine contains 1 x 10^7 TAPA-pulsed dendritic cells and is administered SQ with low-dose GM-CSF following the low-dose cyclophosphamide cycle. A total of six (6) cycles of cyclophosphamide and six (6) DC vaccines cycles will be administered alternating every 14 days.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing TAPA-pulsed DC vaccine in people with Cancer and Metastatic Solid Malignancies, run by Kiromic BioPharma Inc..

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 16 inclusion and 16 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: withdrawn, as of the sponsor's last update on 28 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.

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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 withdrawn before enrolling participants, so there are no results.

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?

Number of adverse events due to administration of TAPA-pulse DC vaccine (time frame: every 7 days up to 5 months). 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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Aug 2018.
