Tisagenlecleucel Cell Therapy Release Checker — Tisagenlecleucel (CAR-T therapy)

ℹ️ Utility checks critical release parameters of tisagenlecleucel (Kymriah):
• Viability (≥70%)
• % CAR-positive cells (20-60%)
• Total viable CAR+ cells (≥1.0E6)
• % CD3+ T-cells (≥60%)
• B-cell contamination (≤5%)
• Mycoplasma (Negative)
• Endotoxins (≤5 EU/dose)
• Vector copy number (0.5-5.0)
• Potency (IFN-gamma ≥1000 pg/mL)

⚠️ CRITICAL: This is a personalized product! Error is unacceptable.
Mycoplasma or low viability leads to batch rejection.

Usage:
TisagenlecleucelQualityChecker.exe → demo mode (console output)
TisagenlecleucelQualityChecker.exe input.csv output.json → evaluate your data

— WHY IS THIS NEEDED?
Tisagenlecleucel (Kymriah) is the first approved CAR-T gene therapy:
• Uses patient's own T-cells modified to attack CD19+ tumor cells
• Used for relapsed/refractory B-cell acute lymphoblastic leukemia (ALL) and lymphoma
• Manufacturing process is individual for each patient (autologous)
• Requires strictest quality control due to risks of cytokine release syndrome and neurotoxicity

⚠️ CRITICAL:
• Viability ≥70% — dead cells do not work and may cause inflammation
• CAR+ cells 20-60% — determines product specificity against tumor
• Dose (cell count) — must be sufficient to achieve remission
• Absence of mycoplasma — absolute safety requirement
• VCN (vector copies) — too high increases oncogenesis risk, too low reduces efficacy
• Potency (functional activity) — confirms cells can kill tumor

Key features:
• Identity check (CAR+, CD3+)
• Purity check (B-cell removal)
• Safety check (mycoplasma, endotoxins, VCN)
• Potency check (functional assay)
• Link to Patient ID (personalized medicine)

Critical parameters:
• Viability: ≥70.0%
• CAR-positive cells: 20.0–60.0%
• Total viable CAR+ cells: ≥1.0E6
• CD3+ cells: ≥60.0%
• B-cell contamination: ≤5.0%
• Mycoplasma: Negative (0)
• Endotoxins: ≤5.0 EU/dose
• VCN: 0.5–5.0 copies/cell
• Potency (IFN-gamma): ≥1000 pg/mL

💡 Usage tips:
1. Analysis performed by Flow Cytometry
2. VCN determined by qPCR
3. Potency measured in co-culture assay with target cells
4. Product stored cryopreserved in liquid nitrogen
5. Any deviation in sterility leads to immediate rejection, as there is no alternative batch for this patient

⚠️ Note: Unlike traditional drugs, CAR-T therapy is a "living drug". Quality depends not only on chemical composition but also on biological activity and cell viability. Each product is unique and intended for only one specific patient.

QA/QC and change control

  • Do not rename columns without updating validator, documentation and test set.
  • Retain input.csv, output.json, executable version and checksum.
  • Before production use, perform IQ/OQ/PQ or equivalent CSV/CSA verification.
  • Critical limits shall be verified against the approved specification, registration dossier and local SOPs.
  • For combination products, document whether the specialized FDC utility or fallback component checks were used.
  • The utility provides structured QC decision support; final release decision remains with QA/QP and approved procedures.
