Tumor Infiltrating Lymphocytes

• Utiliza células T endógenas encontradas em

tumores sólidos, no contexto do paciente

• Se beneficia de um microambiente tumoral rico em

TILs

• Seleção tímica – menos células auto-reativas

• Múltiplos antígenos

• TILs tendem a expressar altos níveis de

checkpoints, como PD-L1 (inibição em conjunto?)

• Tratamento autólogo apenas

• 5-7 semanas de confecção

TIL rest REP

Pre-REP

•Tumor excised, an attempt is

made to grow TILs (5 week

culture)

•Successful TIL culture will

grow a minimum of 50 million

TIL

•Current success rate of

around 65%

•TILs are cryopreserved

•TILs are thawed, rested and rapidly

expanded over 14 days

•Patient is admitted to hospital on day 7 of

the REP and undergoes lymphodepletion •Patient is infused

•2 cycles of HD IL-2 completed

Conclusões

• Terapia celular pode levar à respostas profundas e

duradouras em população refratária a tratamentos

convencionais

• Comercialização é viável

• Melhor compreensão de antígenos e mecanismos

de resistência são necessários
