Axicabtagene Ciloleucel Cell Therapy Release Quality Checker — CAR-T Therapy Release Control

ℹ️ Utility checks critical parameters for CAR-T therapy product release:
• Viability: ≥70%
• Total Viable Cells: 2–10 x 10^6/kg
• CAR Positive Cells: ≥50%
• CD3+ Cells: ≥90%
• CD4/CD8 Ratio: 0.5–5.0
• Endotoxin: ≤5 EU/mL
• Mycoplasma: Not Detected
• Sterility: Not Detected
• Vector Copy Number (VCN): ≤10

⚠️ CRITICAL: This is a live autologous product. Contamination or low viability is unacceptable.
Low level of CAR-positive cells reduces therapy efficacy.

Usage:
AxicabtageneCiloleucel_CellTherapyReleaseQualityChecker.exe → demo mode
AxicabtageneCiloleucel_CellTherapyReleaseQualityChecker.exe input.csv output.json → evaluate data

Input format:
BatchNumber,ViabilityPercent,TotalViableCellsPerKg,CARPositivePercent,CD3PositivePercent,CD4CD8Ratio,EndotoxinEUPerMl,MycoplasmaDetected,SterilityDetected,VectorCopyNumber

Example (0=Neg, 1=Pos):
AXI-CTL-2026-001,85.0,4.5,65.0,95.0,1.8,2.5,0,0,3.2

— WHY IS THIS NEEDED?
Axicabtagene ciloleucel (Yescarta) is an autologous CAR-T immunotherapy for lymphoma:
• Patient's T-cells are modified with Chimeric Antigen Receptor (CAR)
• Targets CD19 antigen on tumor B-cells
• Manufacturing process is individual for each patient
• Requires strict control of viability, potency, and safety

⚠️ CRITICAL:
• Viability ≥70% — necessary for cell survival after infusion
• Dose 2–10 x 10^6 cells/kg — therapeutic window
• CAR Positive ≥50% — indicator of successful transduction and potency
• CD3+ ≥90% — confirmation of T-cell identity
• CD4/CD8 Ratio — balance of immune response
• Endotoxin ≤5 EU/mL — safety for IV administration
• Mycoplasma/Sterility — absence of contamination is mandatory
• VCN ≤10 — limitation of genotoxicity risk (insertional mutagenesis)

Key features:
• Potency assessment via CAR-positive cell percentage
• Identity (CD3+) and subset (CD4/CD8) control
• Strict microbiological criteria for live cell product
• Genetic modification safety assessment (VCN)

Critical parameters:
• Viability: ≥70%
• Total Viable Cells: 2–10 x 10^6/kg
• CAR Positive: ≥50%
• CD3 Positive: ≥90%
• CD4/CD8 Ratio: 0.5–5.0
• Endotoxin: ≤5 EU/mL
• Mycoplasma: Not Detected
• Sterility: Not Detected
• Vector Copy Number: ≤10 copies/cell

💡 Usage tips:
1. Viability determined by flow cytometry or automated counter
2. CAR expression measured using specific anti-CAR antibodies
3. VCN determined by qPCR
4. Sterility and mycoplasma tests may take several days (rapid methods used for release)
5. Product stored cryopreserved until thawing at bedside
6. Any deviation in sterility leads to immediate batch destruction

⚠️ Note: Unlike traditional drugs, each batch is unique (autologous product). Release criteria are adapted to individual patient characteristics (dose per kg body weight). Safety is the absolute priority due to risk of cytokine release syndrome and neurotoxicity, which can be exacerbated by impurities or contamination.

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.
