Safety profile (in patients who received ≥1 dose of study drug)
Current analysis 3rd April Dr. Larkin AACR 2017:
• Per protocol, a total of 644 deaths were projected to occur at 28 months
(99% power to detect a HR of 0.65 for each NIVO-containing arm vs IPI)
-> However, the actual number of deaths was 28% lower than anticipated (95%
power to detect a HR of 0.65 vs IPI)
• The study was not powered for a comparison between NIVO+IPI and
NIVO
1. Claro racional biológico y consistencia de los
datos a lo largo de los diferentes ensayos clínicos
Rationale
• PD-1 and CTLA-4 are non-redundant immune checkpoints in T cell differentiation and function
• Anti-tumor synergy demonstrated in several murine models
• Both agents are active in metastatic melanoma
Study Population Results
Phase 1 study (CA209-004)
Treated and untreated melanoma
BRAF WT/MT
• ORR with NIVO+IPI up to 53% • CR with NIVO+IPI of 18% • 2-year OS rate of 79% • 3 year OS rate of 68%
Phase 2 study (CheckMate 069)
Untreated melanoma
BRAF WT/MT
• Compared with IPI alone, NIVO+IPI significantly improved ORR and PFS • ORR of 59% with NIVO+IPI vs 11% with IPI alone • Higher OS rate at 2 years: 69% for NIVO+IPI vs. 53% for IPI alone • Treatment-related grade 3-4 Aes: 54% with NIVO+IPI vs 24% with IPI alone
Phase 3 study (CheckMate 067)
Untreated melanoma
BRAF WT/MT
• Nivo alone and NIVO+IPI significantly improves OS, PFS and ORR vs IPI alone
• ORR of 59% with NIVO+IPI vs 19% with IPI alone • Higher OS rate at 2 years: 64% for NIVO+IPI vs. 45% for IPI alone • OS, PFS and ORR are numerically greater with NIVO+IPI vs NIVO • Treatment-related grade 3-4 Aes: 58% with NIVO+IPI vs 27% with IPI alone • Most AES managed and resolved in 3-4 weeks (85-100%) • ORR 70% for those patients who discontinued NIVO+IPI for toxicity

Safety Summary• With an additional 19 months of follow-up, safety was consistent with the initial report1
• Most select AEs were managed and resolved within 3-4 weeks (85–100% across organ categories)
• ORR was 70.7% for pts who discontinued NIVO+IPI due to AEs, with median OS not reached

Manejo de los efectos adversos INMUNOMEDIADOS
• Educación del paciente y del personal sanitario que interacciona con él.
• El paciente debe ser evaluado antes de cada dosis de tratamiento.
• Laboratorio: TSH, LDH, bioquímica con perfil hepático
• Repaso de la sintomatología más frecuente.
• Manejo de efectos adversos en función de la gravedad de los mismos y de
los ALGORITMOS establecidos.
• Inicio precoz de del tratamiento de soporte en todos los eventos
adversos y del tratamiento con corticoterapia (en caso de toxicidad
moderada/grave)
• Leve: tratamiento de soporte, monitorización
estrecha
• Moderado: parar el tratamiento, valorar
corticoides
• Grave: discontinuar permanentemente el
tratamiento, inicio de corticoides
DC = patients who discontinued due to an AE; no DC = patients who did not discontinue due to an AE; NR = not recorded.

• La combinación IPI+NIVO presenta de manera estadísticamente significativa un
mayor beneficio en cuanto a OS y PFS respecto a IPI en pacientes afectos de
melanoma metastásico.
• En un análisis descriptivo:
• NIVO+IPI obtiene numéricamente un mayor beneficio en cuanto a OS, PFS y
ORR vs NIVO
• Dichos resultados son superiores para IPI+NIVO incluso en aquellos subgrupos
de pacientes más relevantes: BRAF mutados, LDH elevada, M1 SNC (ORR
50%), PD-L1 bajo expresores (<5% o <1%):
• Aunque la curvas de OS son parecidas para la población alta expresora de
PD-L1 (>5% o >1%), IPI+NIVO presentó una mayor tasa de ORR vs NIVO
independientemente del nivel de expresión de PD-L1
• La mediana de duración de respuesta resulta ser mayor para IPI+NIVO
• El tiempo medio a segunda línea de tratamiento no se ha alcanzado para
IPI+NIVO
• El perfil de toxicidad de IPI+NIVO es consistente en todos los estudios, con un 58% de
eventos grado3-4, una tasa de discontinuación del 40% pero un 70% de los
pacientes que discontinúan el tratamiento se siguen beneficiando del mismo.
• El 50-60% precisan tratamiento inmunosupresor, el 85-100% de los efectos
adversos se resuelven en 3-4 semanas con tratamiento médico.
