Objectives
1.Review the current status of immunotherapy
2. Identify determinants of response
3.Discuss strategies to enhance efficacy

Patient achieved a PR but 4 months later a surveillance scan revealed liver metastases. His sister is a nurse and they want to know about immunotherapy.
Case PresentationDW is a 54-year-old white male with a T2aN3M0, Stage III-B squamous carcinoma of the left lung diagnosed in December 2013. The patient received concurrent chemoradiation therapy with weekly pacltaxel and carboplatin followed by two cycles of full dose paclitaxel + carboplatin.

I informed the patient that an immune checkpoint inhibitor (ICI) was not FDA approved. I evaluated him for an ICI clinical trial but he was ineligible due to lack of tissue and he was too anxious to wait for a biopsy to be performed and analyzed.
What would you recommend?1.Gemcitabine and carboplatin2.Docetaxel3.Docetaxel and ramicirumab4.Gemcitabine5.RFA to the two liver lesions

The patient was treated with docetaxel for 4 cycles and progressed in the liver with multiple new lesions. He underwent a liver biopsy and was placed on a phase I trial of an PDL-1 inhibitor. He is s/p 2 cycles with a MR

Basic Immunology
The innate response is the rapidrecognition and eradication of invading pathogens (macrophages, monocytes, eosinophils, NK cells) and soluble mediators (activation of the complement cascade and acute phase reactants)
Activation of the innate response triggers the expression of costimulatory molecules and cytokines that allows for the specific adaptive response by cellular (T and B cells) andhumoral elements.
Activation requires antigenic fragments be presented by MHC to antigen specific receptors on cytotoxic (CD8) T cells

Comparison: RECIST-irRC Criteria*
Complete Response (CR)
Disappearance of all extranodal target lesions. All pathological lymph nodes must have decreased to <10 mm in short axis
Disappearance of all lesions in two consecutive observations not less than 4 weeks apart
Partial Response (PR) At least a 30% decrease in the SLD of target lesions, taking as reference the baseline sum diameters
≥50% decrease in tumor burden compared with baseline in two observations at least 4 weeks apart
Stable Disease (SD) Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD
50% decrease in tumor burden compared with baseline cannot be established nor 25% increase compared with nadir
Progressive Disease (PD)
SLD increased by at least 20% from the smallest value on study (including baseline, if that is the smallest)The SLD must also demonstrate an absolute increase of at least 5 mm (two lesions increasing from 2 mm to 3mm, for example, does not qualify)
At least 25% increase in tumor burden compared with nadir (at any single time point) in two consecutive observations at least 4 weeks apart
*Total Burden=SPD index lesions + SPD new, measurable lesions
RECIST irRCNew, measurable lesions (i.e. ≥5 x 5 mm)
Always represent PD Incorporated into tumor burden
New, nonmeasurable lesions (i.e. <5 x 5 mm)
Always represent PD Do not define progression (but preclude irCR)
Non-index lesions Changes contribute to defining BOR of CR, PR, SD, and PD
Contribute to defining irCR (complete disappearance required)

• Anti- PD1 vs. Anti-PDL1?• Ideal schedule/duration of therapy?• Will/should PDL1 status guide treatment?• Sequencing/Maintenance Therapy? • Optimal Combinations?• Mechanisms of Resistance?

• Immune checkpoint inhibitors represent a new class of agents that are showing great promise for the treatment of advanced NSCLC.
• Immune checkpoint inhibitors have a distinct toxicity profile and response assessment that must be taken into account in treating patients with these agents.
• Immune checkpoint inhibitors represent the first of several strategies targeting the immune system for therapeutic benefit.
