Carboplatin in patients “unfit” for

cisplatin

• Data suggests that CDDP > carbo in terms of efficacy

– MA Galsky Annals 2011 : CDDP > Carbo wrt CR, ORR

– Multiple phase II studies reveal CDDP > Carbo in terms of ORR

• EORTC 30896 (ASCO 2010)

– G/Carbo vs M-CAVI (M, V and Carbo) in pts CCT 30-60, PS 2

– OS same (about 8.5 mths); G/Carbo better tolerated

• Definition of pts unfit for CDDP (Galsky, JCO June 2011)

– ECOG 2

– CCT < 60

– ≥ G2 hearing loss or ≥ G2 neuropathy

– NYHA III CCF

IMvigor 210: Study Design

• Single-arm phase II study with 2 cohorts

Rosenberg JE, et al. Lancet. 2016;387:1909-1920

Primary endpoints: confirmed ORR by RECIST v1.1 (per central review), ORR per immune-modified RECIST (per investigator)Secondary endpoints: DoR, PFS, OS, safety

12

Post platinum – Responses

• Responses seen in all PD-L1 IC subgroups; higher response seen with higher PD-L1 status

• After a median follow-up of 11·7 months, the median duration of response was not yet reached in

any of the PD-L1 subgroups (range 2·0–13·7 months)

• At the time of the updated data cutoff, ongoing responses were reported in 38 (84%) of the 45

responding patients

• The median time to response was 2·1 months (95% CI 2·0–2·2)

13

Post platinum – Conclusion

• Targeting PD-L1 with atezolizumab is effective in heavily pretreated

patients with locally advanced or metastatic urothelial carcinoma

• Responses were seen in all PD-L1 expression subgroups

• Higher response rates in patients with higher levels of PD-L1

expression on immune cells

• Data led to FDA accelerated approval of atezolizumab for advanced

or metastatic UC after PD during or following platinum-based

therapy

14

Cohort 1 (Previously untreated and

cisplatin ineligible)

• Many patients are cisplatin ineligible due to poor

performance status, impaired renal function, or

comorbidities

• Non-cisplatin–based regimens associated with short

response duration, lack of survival benefit, high

discontinuation rate

• Many patients do not end up receiving systemic

treatment

15

Cisplatin ineligible – Survival

• No clear difference in OS between PD-L1 subgroups

• Median OS was not reached in patients with no risk factors

• 13·4 months in patients with one risk factor (either visceral metastases or ECOG 2)

• 6·2 months in patients with two risk factors

• 19·1 months median OS reported in the stable disease subgroup

16

Cisplatin ineligible – Conclusion

• Durable responses to atezolizumab in previously untreated cisplatin-

ineligible patients metastatic urothelial carcinoma

– Responses seen in all PD-L1 subgroup

• Survival to date appears favourable

• Low incidence of AE despite numerous co-morbidities

17

Was the accelerated approval too early?

IMvigor211 – Conclusion

• The primary endpoint of OS was not met in the IC2/3 population

• Due to delayed separation of the Kaplan-Meier curves, the

differences in mOS and HR do not fully reflect the clinical activity

achieved with atezolizumab

• The safety data showed no new safety signals and demonstrated a

more favorable safety profile for atezolizumab than for

chemotherapy

Summary

• Chemotherapy still has an important role in the management of mBC

• We have 5 IO drugs with some data for use in mUC but only one with phase III trial data to support its use (Pembrolizumab)

• Biomarker studies seem to show a relationship but not clear

• Accelerated approval does not guarantee phase 3 trial success

• More IO drugs and combination trials are ongoing

• Cost will play a big role in its usage and access in non reimbursable markets

Outline

• Current standards

• Immunotherapy in mBC

• Immunotherapy in mRCC

• Summary

Rationale for Immunotherapy in RCC

• Spontaneous remissions attributed to the immune system of advanced RCC have been observed1

• RCC exhibits immune cell infiltrates, and several immune escape mechanisms have been reported in RCC2,3

• Historically, the mainstay of treatment for patients with mRCC was immunotherapy with interleukin-2 or interferon-α1

• Immuno-Oncology (I-O) is an evolving treatment modality encompassing agents designed to directly harness the patient’s own immune system to fight cancer7,8

Real world data: Treatment-related AEs in ≥1% of patients

• Treatment-related grade 3–4 AEs occurred in 27 (7%) patients• AEs were generally manageable with treatment according to protocol-specified guidelines• No treatment-related deaths were reported

Checkmate 025 - Conclusions

➢ Nivolumab significantly improved efficacy compared to everolimus in previously treated pts with advanced metastatic RCC.

▪ Median OS: 26 months (Nivolumab) vs 19.7 months (Everolimus) (hazard ratio, 0.73; P = 0.002).

▪ ORR 25% (nivolumab) vs 5% (Everolimus) (OR: 1.72; P = .0246)

➢ All-grade and grade 3/4 toxicity were lower with nivolumab compared to everolimus.

➢ The survival improvement and favorable safety profile demonstrated provides evidence for nivolumab as a potential new treatment option for previously treated patients with mRCC.

Real world data - Conclusions

• The EAP population included some subgroups that were poorly represented or

not represented at all in the pivotal CheckMate 025 study3

• Despite these differences, comparison of the survival curves suggests that the 9-

month OS rate (73%) in the EAP approached that observed in the nivolumab

arm of the CheckMate 025 trial3

• As in CheckMate 025,4 some patients treated beyond progression derived

further benefit with improved tumor response

• The safety profile of nivolumab appeared consistent with that reported in the

CheckMate 025 trial3

• Noting the limitations of this study type, preliminary data from this EAP appear to

confirm data from the pivotal trial and suggest that nivolumab is effective for the

treatment of metastatic RCC in routine clinical practice

Outline

• Current standards

• Immunotherapy in mBC

• Immunotherapy in mRCC

• Summary

61

Summary

• IO has an established role in the treatment of mRCC( Nivolumab)

• New standard established with recent IO data in first line mRCC ( int/ poor risk)

• A number of ongoing studies in the first line setting with IO combination studies show promise

• Cost and access present a major challenge which needs to be overcome
