Non-profit, open-licence lentiviral vectors and producer cell lines for CAR-T

The engineered virus that delivers the CAR gene costs tens of thousands of dollars per patient and is controlled by a few suppliers. A non-profit supplier with open licences would cut that cost sharply.

Vector is often the single largest material cost in autologous CAR-T and a frequent cause of manufacturing delay; capacity is concentrated among a few contract suppliers and licences are restrictive. Caring Cross and several academic centres have shown that non-profit vector production can supply clinical programmes at a fraction of the cost. The proposal is a foundation-funded vector consortium with stable producer cell lines, a shared plasmid bank for common CARs (CD19, BCMA, CD22) under open licences for non-commercial and low-income-country use, and GMP production at cost.

Hypothesis
Consortium vector supplied at cost reduces vector cost per CAR-T dose to below $5,000 and enables at least ten new academic or LMIC CAR-T programmes to reach the clinic within five years.
Rationale
Vector production is a mature process whose price reflects concentration and licensing more than inherent cost; stable producer lines remove the plasmid transfection step that drives variability and expense.
What would test it
Fund the consortium to produce GMP vector for three academic CD19 programmes, audit cost per dose and release success rate against commercial contract supply, and count new programmes enabled.
