FusionVAC22_01: Fusion Transcript-based Peptide Vaccine Combined with Immune Checkpoint Inhibition
Recruiting now · Phase 1
Conditions studied: Fibrolamellar Hepatocellular Carcinoma
In brief
The aim of this clinical trial is to evaluate the immunogenicity along with safety and toxicity as well as first efficacy of a DNAJB1-PRKACA fusion transcript-based peptide vaccine (Fusion-VAC-XS15) in combination with anti-programmed cell death-ligand 1 immune checkpoint inhibition (ICI) by Atezolizumab (TecentriqTM) in patients with Fibrolamellar hepatocellular carcinoma (FL-HCC) or other cancer entities carrying the DNAJB1-PRKACA fusion transcript.

You may qualify if…
- Ability to understand and willingness to sign a written informed consent document.
- Histologically confirmed FL-HCC or other malignant disease that is locally advanced or metastatic.
- Non-FL-HCC patients can be included
- in case of disease progression after therapy and fulfilling at least one of the following criteria: i. no further standard therapy is available. ii. patient is considered unsuitable for further available standard therapy. iii. patient is unwilling to receive treatment with available standard therapy.
- if no standard therapy exists.
- Presence of DNAJB1-PRKACA fusion transcript, assessed by RNA-based next-generation sequencing (NGS) or realtime-polymerase chain reaction amplification (RT-PCR).
- Age ≥18 years.
- Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1.
- Patients must have measurable disease per iRECIST (Response Evaluation Criteria in Solid Tumours).
- Negative SARS-CoV-2 rapid antigen test (as long as World Health Organization declares pandemic spread of SARS-CoV-2).
- Adequate organ function laboratory values
- Absolute Lymphocyte Count > 500/μl
- Platelets > 50.000/μl

- Female patients of child bearing potential (FCBP) and male patients with partners of child bearing potential, who are sexually active, must agree to the use of two effective forms (at least one highly effective method) of contraception. This should be started from the signing of the informed consent and be continued until 5 months (both female and male patients) after last dose of an Atezolizumab (TecentriqTM) or vaccination.
- For FCBP two negative pregnancy tests (sensitivity of at least 25 mIU/mL) prior to first application of a study drug (vaccination at visit V1), one at screening and the other one at visit V1 prior (<24h) to first vaccination.
- Postmenopausal or evidence of non-child-bearing status.
You may not qualify if…
- Pregnant or breastfeeding.
- Unwilling or unable to follow the study schedule for any reason.
- Chemotherapy or other systemic therapy or radiotherapy, up to 14 days prior to the first dose of study drug.
- Concurrent or previous treatment within 30 days in another interventional clinical trial with an investigational anticancer therapy or any other investigational therapy, which would interfere with the study's primary and secondary endpoints.
- Major surgery within 28 days of dosing of study drug.
- Have not recovered from adverse events to grade ≤ 2 or baseline due to previous agents administered excluding alopecia and neurotoxicity (≤ 2 grade).
- History of autoimmune phenomena due to treatment with immunotherapy agents (including, anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CTLA4 antibodies, etc.) (≥ grade 3).
- Treatment with immunotherapy agents (including, anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CTLA4 antibodies, etc.) within 28 days prior of dosing of study drug.
- Have received any live vaccine within 28 days prior to study treatment.
- Known sensitivity to or history of allergic reactions to any of the investigational drugs or known hypersensitivity to Chinese hamster ovary cell products.
- History of severe allergic anaphylactic reactions to chimeric, human or humanized antibodies, or fusion proteins.
- Has active autoimmune disease that requires or has required systemic immunosuppressive treatment in the past 2 years.
- Presence of any tissue or organ allograft, regardless of need for immunosuppression, including corneal allograft. Patients with a history of allogeneic hematopoietic stem cell transplant will be excluded.
- Has a diagnosis of immunodeficiency.
- Systemic treatment with either corticosteroids (>10 mg daily prednisone equivalents) or other immunosuppressive medications within 7 days prior to study drug administration.
- Symptomatic interstitial lung disease.
- Active or untreated brain metastases or leptomeningeal metastases.
- Uncontrolled intercurrent illness including, but not limited to, uncontrolled infection, symptomatic congestive heart failure, unstable angina, cardiac arrhythmia, different metastatic cancer than the one leading to study enrollment, or psychiatric illness/social
