Description of intervention(s) / exposure
Treatment: Drugs - GSK3845097
Treatment: Drugs - Cyclophosphamide
Treatment: Drugs - Fludarabine

Experimental: GSK3845097 - Eligible participants will be leukapheresed to manufacture engineered T-cells. Participants will then receive high dose of GSK3845097 after completing lymphodepleting chemotherapy. The first study participant receiving GSK3845097 will receive the total assigned dose as 2 separate infusions 7 days apart, in aliquots of 30% (first infusion) and 70% (second infusion) of the total target dose , respectively. Based on the dose limiting toxicities reported in the first participant, then all subsequent participants treated with GSK3845097 will receive the full dose as a single, i.e., one-time, infusion.


Treatment: Drugs: GSK3845097
GSK3845097 was administered.

Treatment: Drugs: Cyclophosphamide
Cyclophosphamide was administered as lymphodepleting chemotherapy.

Treatment: Drugs: Fludarabine
Fludarabine was administered as lymphodepleting chemotherapy.
