The Report
- Whole-exome sequencing of tumor and normal tissue
- Whole tumor transcriptome
- Identification of tumor-specific nonsynonymous mutations (mutations that may lead to altered protein sequences)
- Compilation of a clinical report including treatment recommendations
- Genotyping of the patient’s HLA molecules
- Prediction of which tumor-specific mutated peptides are most probably presented on the tumor cell surface by the patient-specific HLA types using novel computational methods
- Database analysis to investigate the expression of the respective genes in this tumor type
- Analysis of which peptides can be synthesized and dissolved in an injectable solution
- Selection and recommendation of peptides which are predicted to elicit the most powerful immune response against the tumor: compilation of report.
Based on these analyses, to manufacture the personalized tumor neoantigen-specific peptide vaccine, the following steps have been performed:
- Synthesis of the desired number of peptides
- Preparation and quality control of the injectable multi-peptide vaccines (sufficient doses for one year)
The personalized vaccine is applied along with an adjuvant (typically GM-CSF, Leukine® or Aldara®) to increase the stimulation of the immune system.
Repeated vaccinations are now being performed regularly according to a fixed treatment plan. The plan includes
- A priming phase (4 vaccinations within 10 to 12 days) and
- Subsequent monthly injections for about 10 months.
First vaccination: 23.08.2021
Application of the personalized vaccine together with Aldara® and Leukine® and blood draw for immune monitoring
Second vaccination: 24.08.2021
Application of the personalized vaccine together with Aldara® and Leukine®
Third vaccination: 25.08.2021
Application of the personalized vaccine together with Aldara® and Leukine®
Fourth vaccination: 26.08.2021
Application of the personalized vaccine together with Aldara® and Leukine®
After these priming injections, we recommend administering boosting vaccinations every 4 to 6 weeks. To the best of our knowledge and according to our experience, the treatment is in general well-tolerated. We were happy to see that you tolerated the first four vaccinations very well.
Monitoring the immune response to the treatment is important for gauging its success and can help prevent potentially more severe side effects. As such immune monitoring is strongly recommended as an important
monitoring mechanism along with the vaccine treatment. We recommend doing the monitoring when Mohammed Banat will be here for the seventh vaccination.
For immune monitoring, blood is collected during the first injections and every 3 to 4 months thereafter. Immune cells (T cells and antigen presenting cells) are isolated and incubated with peptides of the vaccination cocktail. T cells specifically activated by a peptide will be identified by intracellular cytokine staining and FACS analysis. The patient receives a report highlighting the vaccine peptides that induced a significant immune (T cell) response. This information can in turn be used to control the immunogenicity of the vaccination regime and to further adjust the treatment plan.
From a clinical perspective immune monitoring is the only way to monitor the immune system. It is also the only way to quantitatively gauge the efficacy of the vaccine therapy. This information is also critical for effectively timing and spacing the vaccine injections for maximum impact.
My Experience
Second Trip (6th Vaccination)

These were ones that I never had before (and never had afterwords in the following scheduled vacccines).
- Around 1 PM:

My whole body is in pain almost everywhere- lack back pain
- back of chest pain
- back of knee pain
- back of neck pain
- heel of foot pain

- Around 3:00
- Loss of energy (fatigue): It was difficult to stay standing (not
enough power + feeling cold). I had to sit to take
rest.

- I had to run to the hotel and take a hot shower (that calmed down the
“chill” feeling). - I decided to continue to be in bed for now.
- The rest of the pain continues but is reduced. The remaining
pain is focusing on the lower back (the rest is easier).

There is a list of things that I did not have at any point in time:
- Headaches
- Losing further focus
- Seizures or auras
- Sore throats
