2 A very special thank you to our partners

3 Hope through advances in lung cancer treatments Lung cancer continues to be the single largest cancer killer of men and women in the US 1 Research remains very much underfunded BUT, there is HOPE Important advances are being made in lung cancer diagnosis and treatment 1. American Cancer Society. Cancer Facts & Figures Atlanta: American Cancer Society; American Cancer Society. Cancer Facts & Figures 2018.

4 Research is the driver of change in the treatment of lung cancer Basis for changing clinical practice and improving outcomes: FDA approvals New drugs New ways to use existing drugs Removal of approval of drugs or specific uses of drugs Changes to the National Comprehensive Cancer Network (NCCN) Guidelines Help determine clinical practice, ie, how patients are treated Usually quickly updated in response to FDA approvals FDA approvals, NCCN guidelines, and other recommendations are driven by research

30 Immunotherapy

31 Immune Cells Types of WBCs Neutrophils Important in fighting bacteria Macrophages Important in fighting any foreign substance Lymphocytes The generals of the immune system Several different types of lymphocytes Tell other immune cells what to do B-lymphocytes: Make antibodies Joan s oversimplified version of immunity and cancer Lymphocytes Lymphocytes Lymphocytes Lymphocytes T-Lymphocytes or T cells are important in fighting any foreign substance, such as cancer cells

32 What s supposed to happen: T-lymphocytes (T cells) monitor the body for things that aren t supposed to be there *Joan s embarrassingly overly simplified version of the immune system

33 What s supposed to happen: When T-cells recognize cancer cells as foreign = PD-1 *Joan s embarrassingly overly simplified version of the immune system

34 And become activated, allowing the T-cells to attack the tumor = PD-1 *Joan s embarrassingly overly simplified version of the immune system

35 What sometimes happens: Cancer cells make checkpoint proteins such as PD-L1 to mask the T- cells, by binding to PD-1 on the T cells, = PD-1 = PDL1 *Joan s embarrassingly overly simplified version of the immune system

36 What sometimes happens: Cancer cells make checkpoint proteins such as PD-L1 to mask the T-cells, by binding to PD-1 on the T cells, = PD-1 = PDL1 *Joan s embarrassingly overly simplified version of the immune system

37 What sometimes happens: Thus rendering the cancer cell invisible to the T cell* = PD-1 = PDL1 *Joan s embarrassingly overly simplified version of the immune system

38 What to do??? Anti-PD-1 antibodies stop the PD-L1 from binding to the PD-1 on T-cells Nivolumab, Pembrolizumab = PD-1 = Anti PD-1 *Joan s embarrassingly overly simplified version of the immune system

39 Anti-PD-L1 antibodies also stop PD-L1 from Binding to PD-1 on T-cells Atezolizumab, Durvalumab = PD-1 = Anti PD-L1 *Joan s embarrassingly overly simplified version of the immune system

40 Thus allowing the T-cells to see the cancer cell and attack = PD-1 = Anti PD-L1 *Joan s embarrassingly overly simplified version of the immune system

46 FDA-approved immunotherapies Type Drug Use in first-line therapy? PD-1 inhibitor PD-L1 inhibitor Use with chemo? Use after chemo stops working? Requires PD-L1 testing? Nivolumab/ Opdivo No No Yes No Pembrolizumab/ Keytruda Yes Yes* Yes No** Yes Atezolizumab/ Tecentriq No No Yes No *Pembrolizumab is approved in combination with chemotherapy (pemetrexed and carboplatin) in patients with non-squamous NSCLC **When used with chemotherapy When used by itself for initial therapy (PD-L1 expression 50%) or after chemo stops working (PD-L1 expression 1%) These are not all of the FDA-approved indications FDA.gov.

47 Possible side effects of immunotherapy Part of the body Possible side effects Possible symptoms Lung Inflammation of the lungs (pneumonitis) Shortness of breath Cough Chest pain Intestine Inflammation of the colon (colitis) Diarrhea Pain in the stomach area Liver Inflammation of the liver (hepatitis) Dark urine Feeling less hungry Thyroid or other hormone glands Thyroid problems, such as underactive thyroid (hypothyroidism) Feeling cold Headaches Weight loss or gain Kidney Inflammation of the kidney (nephritis) Change in the amount or color of your urine Infusion reactions Skin or other organs Rash Eye problems Muscle problems Side effects related to IV administration Chills Fever These are not all the possible side effects of immunotherapy Rash or itching Rash Changes in eyesight Muscle pain or weakness Information obtained from Full Prescribing Information for approved immunotherapies available at FDA.gov.

48 Many more trials of immunotherapy Combinations Awaiting full results of KEYNOTE-189 trial of frontline pembrolizumab with pemetrexed (Alimta ) and either cisplatin or carboplatin New ways to use immunotherapy Neoadjuvant and adjuvant studies eg, LCMC 3 trial of atezolizumab before and after surgery New drugs under FDA review Durvalumab (Imfinzi ) after chemoradition in patients with stage 3 disease (Pacific trial) Studies of immunotherapy in small cell lung cancer (discussed in next sections)

49 PACIFIC trial may change clinical practice Active monitoring after chemoradiation was the standard of care for patients with locally advanced (Stage III) lung cancer whose tumors could not be removed by surgery PACIFIC trial looked at benefit of immunotherapy after chemoradiation Immunotherapy Patients with Stage III, locally advanced, unresectable NSCLC Chemoradiation treatment (CRT) Placebo Antonia SJ, et al.

51 Practical issues in immunotherapy How best to select patients likely to respond Biomarkers: Does the amount of PD-1 or PD-L1 in a tumor matter? Measure them or not? Logistical issues with obtaining biomarkers What about tumor mutation burden? Optimal dosing How long to give? Understanding hyperprogression Cost

52 Tumor mutation burden (TMB) TMB is a measure of mutations carried by a tumor Determined by the number of mutations in a specific area of genetic material, such as mutations: In a single cell In an entire tumor Per area of building blocks of DNA Potential marker of sensitivity to immunotherapy Higher TMB may mean more likely to respond to immunotherapy Hot off the press (2/2018): CheckMate-227 showed that TMB is a predictive biomarker that can identify people with NSCLC who may benefit from the nivolumab + ipilimumab combination Full results of the study to follow

53 Small cell lung cancer

60 CAR-T cell therapy

61 What s supposed to happen: T-cells recognize cancer cells as foreign But how do they do that? = PD-1 *This was one of Joan s many over-simplifications

62 What s supposed to happen: T-cells recognize cancer cells as foreign But how do they do that? = PD-1 *How they recognize the cancer cells was one of Joan s many over-simplifications

63 By recognizing proteins on the tumor cell as abnormal, or foreign. To do this, they need to have the proper receptor, like a hook and chain = PD-1 *This was one of Joan s many over-simplifications

64 T-cells need BOTH to see the cancer cell they need to have their PDL1 receptors open, AND they need to hook up to the cancer cell = PD-1 *This was one of Joan s many over-simplifications

65 But what happens if the T cells don t have the proper receptor? = PD-1 *This was one of Joan s many oversimplifications

66 CAR-T makes the proper receptor on the patient s T cells Image from MSKCC; available online at: mskcc.org/blog/car-t-cell-therapy-growing-area-research

67 CAR-T is an exciting new approach to treating cancer Cells are taken from the patient, filtered, and reprogramed to express the correct hook to target the cancer cell They are then grown and multiplied in the lab, and then returned to the patient Once returned to the patient, the cells can continue multiplying and could fight disease for months or years Two CAR-T cell therapies are FDA approved for blood cancers (2017) CAR=chimeric antigen receptor

68 Key take-aways Advances in treatments for lung cancer Happened through research! Incredible advances have been made But, more research is needed to improve survival!

69 Building a movement WE CANNOT DO IT WITHOUT YOU There is strength in numbers!! Participating in this conference is a first step.
