11 High-Dose IL-2 Therapy: Durable Responses Seen
High-dose IL-2 produces durable responses in 16% of pts with advanced melanoma Few relapses in pts responding for over 2.5 yrs (likely cured) FDA approval in 1998 for melanoma Metastatic Melanoma (N = 270) 1.0 CR (n = 17) PR (n = 26) CR + PR (n = 43) 0.8 0.6 Probability of Continuing Response HD, high-dose; IL-2, interleukin-2; RCC, renal cell carcinoma; FDA, US Food and Drug Administration. Speaker notes: To show and emphasize the potential of immunotherapy with the prolonged responses. Also it was unclear why few patients were responding at the time of these studies. 0.4 0.2 10 20 30 40 50 60 70 80 90 100 110 120 130 Duration of Response (Mos) Atkins MB, et al.

12 High-Dose IL-2 Therapy in Melanoma
High-dose IL-2 appears to benefit pts, but: Toxic Complex; must be delivered as an inpatient regimen Use remains limited to selected pts treated at experienced centers Efforts to develop more tolerable regimens unsuccessful Efforts to better select pts who might benefit from high- dose IL-2 therapy have produced modest advances Proof of principle that immunotherapy can produce durable benefit in pts with cancer, but newer immunotherapies are needed HD, high-dose; IL-2, interleukin-2; RCC, renal cell carcinoma.

16 Ipilimumab, gp100, or Both in Advanced Melanoma (MDX010-20): irAEs
All Grades (Grade 3/4) Ipi + gp100 (n = 380) Ipi + Placebo (n = 131) gp100 + placebo (n = 132) Any 58 (9.7/0.5) 61 (12.2/2.3) 32 (3.0/0) Dermatologic 40 (2.1/0.3) 44 (1.5/0) 17 (0/0) Gastrointestinal 32 (5.3/0.5) 29 (7.6/0) 14 (0.8/0) Endocrine 4 (1.1/0) 8 (2.3/1.5) 2 (0/0) Hepatic 2 (1.1/0) 4 (0/0) 5 (2.3/0) Ipi, ipilimumab; irAEs, immune-related adverse events. Speaker notes: Immune-related AEs are those that are inflammatory in nature and cannot be attributed to non-immune causes (e.g. infection is ruled out). These are the most common side effects, as has been reported. This automated computer-generated count is based on a pre-specified list of inflammatory-type AEs (“itis”)…..and, as such, may be an OVER-estimate of the number of truly immune-related events that occurred in each arm. Here, the rate of all irAEs (all grades) is 32% in the gp100 arm and about 60% in the ipi arms. Grade 3 events are uncommon: % compared to 3% in the gp100 arm. The most common type of event is skin-based with rare grade 3 events (~2% GI irAEs, most notably diarrhea and colitis, occurs (at any grade) in approximately 30% of subjects. 6-8% are grade 3. Endocrinopathy, most commonly central adrenal insufficiency occurs rarely. Well-defined treatment algorithms have been established for these. The mainstay of treatment is systemic immunosuppressive agents which lead to complete resolution of the events in most cases and do not appear to interfere with the anti-cancer effect of ipilimumab. Endocrinopathy is the exception. While patients feel better quickly with hormone replacement, the ipilimumab effect on the endocrine system appears to be long-lasting and lifelong hormone replacement is likely required.

18 Ipilimumab: Key to Optimal Patient Management
First Dose: baseline assessment; review medical history, check standard of care lab values including LFTs, TFTs Subsequent doses: before each infusion or as needed, check lab values including AST, ALT, total bilirubin, and thyroid function Conduct thorough assessment of immune-mediated symptoms Educate on importance of detecting and prompt reporting of symptoms Discuss key points about immune-mediated adverse events and importance of prompt medical intervention Confirm patient’s ability to verbalize important symptoms Emphasize that symptoms may be intermittent and can occur wks to mos after treatment is complete A stepwise approach to recommendations for proper and thorough review prior to patients first administration of Ipilimumab. Insuring full standard of care labs profile plus thyroid functions be evaluated. A comprehensive teaching session or follow up to teaching session should be conducted, patient resources such as patient medication hand out and wallet card should be provided. Most importantly, contact information for the office 24/7/365 should be reviewed, what to do during off hours.,Holidays or in the need of seeking emergent care. Patients should be instructed to call at the onset of symptoms and not delay reporting as that may complicate management and interfere with quality of life.

System Symptoms Management GI tract Diarrhea Abdominal pain Dark, bloody stools Moderate enterocolitis: hold ipilimumab, administer antidiarrheal. Persistent diarrhea (> 1 wk): systemic corticosteroids. 7+ stools/day: start methylprednisone, permanently discontinue ipilimumab. Consider infliximab for corticosteroid-refractory pts.

The final edited version in the manuscript is: “All the patients who underwent randomization were followed up for up to 16.7 months at the time of database lock on August 5, 2014, which was 5.2 months after the first visit of the last patient who had undergone randomization.” History: At one point, we have “minimum follow-up was 5.2 months” in the manuscript abstract. This was subsequently removed for word count reason. The mention of minimum follow-up (from last randomization to data cut, 5 Aug 2014) replaced the median follow-up data (8.9 mo for nivo; 6.8 mo for DTIC; not calculated for overall [N=418] population) due to concern that the imbalance in medians might be misinterpreted as greater loss to follow-up in the DTIC arm while in reality this was due to more death. The final version is the result of multiple rounds of edits, including changes by journal editors. 40 Pts who died, n/N Median OS, mo (95% CI) 30 20 Nivolumab 50/210 NR 10 Dacarbazine 96/208 10.8 ( ) 3 6 9 12 15 18 Robert C, et al.

46 Patient Education on Novel Therapies
Patient education should include information on: Adverse reaction profiles that differs from standard chemotherapy Early recognition of irAEs essential for effective treatment irAEs are infrequent, treatable and respond well to steroids Who and when to call for adverse reactions Evaluate pt and caregiver for continued educational needs related to the therapy and disease process Reinforce teaching points at every point of contact, office and treatment visits, and phone contact Patient education should start from prior to therapy onset and through out therapy at every contact point the clinician has with the patient. Patients and their care partner(s) should be included to be active participants in the patients care especially if an adverse effect develops. Emphasis on the importance of maintaining a treatment schedule to optimize the best outcomes and conversly to intervene when an adverse effect develops and interferes with quality of life and potential for continuing treatment.

51 Issues With PD-L1 as a Biomarker
PD-L1 negativity an unreliable biomarker in certain settings Assays are technically difficult, imperfect; results may differ depending on the antibody/assay (tumor vs immune cells) Expression cut-off, tumor heterogeneity, and inducible gene = sampling error (false negative) Archived tissue different than recent biopsy May be more useful in determining which tumors rather than which pts to treat PD-L1 expression may be less relevant for combination therapies PD-L1 expression may be constitutive (no immune infiltrate) PD-L1, programmed death-ligand 1.

53 Conclusions Immunotherapy for melanoma induces responses of long duration and results in prolonged OS Novel patterns of response with checkpoint protein inhibition require new types of response criteria that accommodate progression followed by regression Immune-related adverse events are a unique spectrum of adverse events with checkpoint protein inhibition that require learning new ways to manage toxicity The best is yet to come!
