How to progress in GI cancer treatmentBetter define subgroups

With different prognostic and different treatments

Combine different targeted agents in accordance with the molecular profile

of the patients tumor

Find predictive markers for precision medecine

Induce an efficient immune response from the host

against the tumor

FOR FIRST TISSUE/SITE-AGNOSTIC INDICATION

• Adult and pediatric patients with unresectable or metastatic, MSI-H or dMMR solid tumors that have

progressed following prior treatment and who have no satisfactory alternative treatment options

• or with MSI-H or dMMR colorectal cancer that has progressed following treatment with a

fluoropyrimidine, oxaliplatin, and irinotecan

Non MSI GI cancer will be treatable by anti-PD1 in the future => MSI testing has to be performed in daily practice

Safety SummaryCheckMate 142 Nivolumab alone

Overman M, Lancet Oncol 2017

Page 27: Immunotherapy in GI cancers - congres-sofog.com · Checkpoint blockers Efficacy signal in MSI-H colorectal cancer Le DT, et al. N Engl J Med. 2015;372(26):2509-2520 Radiographic responses*

ConclusionsCheckMate 142: nivolumab alone

• Nivolumab monotherapy provided durable responses and disease control in patients with dMMR/MSI-H CRC

• Responses and disease control were observed regardless of tumor PD-L1 expression, BRAF or KRAS mutation status, or a clinical history of Lynch syndrome

• Patient-reported outcome analyses showed clinically meaningful improvements in functioning, symptoms, and QOL

– Patients who continued treatment for ≥ 19 weeks attained a level of health that would be considered as equal to or exceeding the general health of many populations

• Nivolumab was well tolerated with no new safety signals observed

• These results suggest that nivolumab could be considered a new standard of care for patients with dMMR/MSI-H CRC and warrants further investigation in patients with other dMMR/MSI-H tumors

FDA grants nivolumab accelerated approval for MSI-H or dMMR colorectal cancer

On July 31, 2017, the U.S. Food and Drug Administration granted accelerated approval to nivolumab (OPDIVO, Bristol-Myers Squibb Company) for the treatment of patients 12 years and older with mismatch repair deficient (dMMR) and microsatellite instability high (MSI-H) metastatic colorectal cancer that has progressed following treatment with a fluoropyrimidine, oxaliplatin, and

irinotecan. The approval was based on data from Study CA209142 (CHECKMATE 142; NCT 02060188)

Page 29: Immunotherapy in GI cancers - congres-sofog.com · Checkpoint blockers Efficacy signal in MSI-H colorectal cancer Le DT, et al. N Engl J Med. 2015;372(26):2509-2520 Radiographic responses*

NIVO + IPI provided durable responses, sustained disease control,

and encouraging survival data in pretreated patients with dMMR/MSI-H mCRC

–ORR of 55%, with 79% of patients achieving disease control for ≥ 12 weeks

–85% of responses ongoing, and the median DOR was not yet reached

–88% of patients alive at 9 months, 77% without progression

NIVO + IPI demonstrated a manageable safety profile; 29% of patients had grade 3/4 TRAEs

This trial is ongoing and patients will continue to be followed for survival

41 patients in this study were treated in St Antoine hospital and translational research are planned (we have primary and metastatic tissue for

all)

A French study will began in Septempter 2017 (GERCOR group) with nivolumab and ipilumumab (55 patients) in the same population and we

will collect archival tissue for all patients

Conclusion• Trials are ongoing in mCRC and in the adjuvant setting (soon)

• Colon cancer probably less easy than others

• MSI-H tumors : a good target

• Others may be: PolE, PolD, MSS with immune infiltrates…

• Combination with targeted agents: • + chemotherapy, sequence?• + radiotherapy? • + targeted agents: anti-angiogenics; MEK…?

Rationale for immuno-oncology in GC• Pathology of GC associated

with immune system evasion

• Immunosuppressive proteins expressed on immune cells in patients with GC patients, including key checkpoint inhibitors:1–4

• Cytotoxic T-lymphocyte-associated protein-4 (CTLA-4)

• PD-1

Authors’ Conclusions

57

• Part 1 of this two-part randomized study met its primary and secondary endpoints; nivolumab + chemotherapy regimens (SOX or CapeOX)

had manageable safety profiles and demonstrated clinically meaningful antitumor activity

– Discontinuations due to treatment-related AEs were low (≤10% of patients) and no treatment-related deaths were reported

– The incidence and type of treatment-related AEs were consistent with AEs known to be associated with chemotherapy regimens and

with nivolumab5–9

– Objective responses were observed in more than two-thirds of patients, occurred early, and were durable, with encouraging PFS

• No substantial differences in clinical activity and safety were observed between the nivolumab + SOX and nivolumab + CapeOX treatment

regimens

• These results suggest that nivolumab in combination with SOX or CapeOX chemotherapy in patients with unresectable advanced or

recurrent gastric or gastroesophageal junction cancer may be a first-line therapy option

– Part 2 of this study is currently recruiting patients

Updated KEYNOTE-059 results

• Pembrolizumab continues to demonstrate, in patients with advanced G/GEJ cancer,

• Promising antitumor activity and durable response as monotherapy in patients whose disease hasprogressed after ≥2 prior lines of therapy

• Encouraging antitumor activity in combination with chemotherapy in previously untreated patients

• Encouraging antitumor activity as monotherapy in previously untreated patients with PD-L1-positive tumors

• Responses were regardless of PD-L1 expression, but higher in patients with PD-L1-positive tumors in cohorts 1 and 2

• Safety was manageable and consistent with that previous reports: no new safety signals

• Results support further development of pembrolizumab for advanced G/GEJ cancer

RESULTATS• Taux de réponse :

• 9/37 = 24% (IC95=15-33) en réponse dont 2 réponses complètes, et 1 réponse partielle chez un patient VIH

• 7/9 des répondeurs (78%) ont maintenu cette réponse jusqu'à l'analyse des données (temps médian 5.8mois IC95=3.9-8.1, durée la plus longue à 10.4mois)

• Réponse radiologique de -70% (IC95=57-90)

• Taux de stabilisation : • 17/37 = 47% (IC95=60-63) en maladie stable,

soit au total 72% (IC95=53-84) de contrôle de la maladie à la 1ère évaluation
