5 EMEA RECOMMENDATIONS Points to consider (CPMP/EWP/562/98) on clinical investigation of medicinal products in the chronic treatment of patients with COPD, 1999 In the major efficacy studies of symptomatic benefit the primary endpoint should reflect the clinical benefit the applicant wishes to claim in the future SPC (Summary of Product Characteristics) In the major efficacy studies of symptomatic benefit the primary endpoint should reflect the clinical benefit the applicant wishes to claim in the future SPC (Summary of Product Characteristics) It should include the FEV1 as a measure of lung function and include a measure of symptomatic benefit It should include the FEV1 as a measure of lung function and include a measure of symptomatic benefit A significant benefit for both endpoints, should be demonstrated so that no multiplicity adjustment to significance levels is indicated A significant benefit for both endpoints, should be demonstrated so that no multiplicity adjustment to significance levels is indicated The primary symptomatic benefit endpoint should be justified by referencing published data which supports its validity; one example is the St George’s Respiratory Questionnaire The primary symptomatic benefit endpoint should be justified by referencing published data which supports its validity; one example is the St George’s Respiratory Questionnaire There are number of secondary endpoints which may provide useful information. … e.g. symptom scales, … and quality of life assessment There are number of secondary endpoints which may provide useful information. … e.g. symptom scales, … and quality of life assessment In the major efficacy studies of symptomatic benefit the primary endpoint should reflect the clinical benefit the applicant wishes to claim in the future SPC (Summary of Product Characteristics) In the major efficacy studies of symptomatic benefit the primary endpoint should reflect the clinical benefit the applicant wishes to claim in the future SPC (Summary of Product Characteristics) It should include the FEV1 as a measure of lung function and include a measure of symptomatic benefit It should include the FEV1 as a measure of lung function and include a measure of symptomatic benefit A significant benefit for both endpoints, should be demonstrated so that no multiplicity adjustment to significance levels is indicated A significant benefit for both endpoints, should be demonstrated so that no multiplicity adjustment to significance levels is indicated The primary symptomatic benefit endpoint should be justified by referencing published data which supports its validity; one example is the St George’s Respiratory Questionnaire The primary symptomatic benefit endpoint should be justified by referencing published data which supports its validity; one example is the St George’s Respiratory Questionnaire There are number of secondary endpoints which may provide useful information. … e.g. symptom scales, … and quality of life assessment There are number of secondary endpoints which may provide useful information. … e.g. symptom scales, … and quality of life assessment

6 QOL: The big picture

7 Symptoms and QOL: Is there a difference? If you count the number of emetic episodes, you are assessing a symptom If you count the number of emetic episodes, you are assessing a symptom If you ask the patient how bad their nausea is, you are assessing QOL If you ask the patient how bad their nausea is, you are assessing QOL The measurement issues and analytical procedures are the same The measurement issues and analytical procedures are the same Literature is converging to the term patient-reported outcomes (PRO) Literature is converging to the term patient-reported outcomes (PRO) If you count the number of emetic episodes, you are assessing a symptom If you count the number of emetic episodes, you are assessing a symptom If you ask the patient how bad their nausea is, you are assessing QOL If you ask the patient how bad their nausea is, you are assessing QOL The measurement issues and analytical procedures are the same The measurement issues and analytical procedures are the same Literature is converging to the term patient-reported outcomes (PRO) Literature is converging to the term patient-reported outcomes (PRO)

48 SummarySummary Uniscale demonstrates greater variability than the multiple-item indices The Uniscale is better able to detect a CSD in QOL than the multiple item assessments, and captures a CSD earlier than the multiple item assessments Correlations and percent agreement between Uniscale and multiple-item assessments were modest Uniscale demonstrates greater variability than the multiple-item indices The Uniscale is better able to detect a CSD in QOL than the multiple item assessments, and captures a CSD earlier than the multiple item assessments Correlations and percent agreement between Uniscale and multiple-item assessments were modest

49 SummarySummary There is indication that a CSD in QOL occurs earlier than CTC AE reporting Consistent with a recent finding that single-item QOL assessments detect a patient-perceived problem in peripheral neuropathy more than six weeks earlier than CTC (Morton et al, ASCO 2005) The multiple-item assessments are in better agreement with occurrence or CSD in AE compared to the Uniscale There is indication that a CSD in QOL occurs earlier than CTC AE reporting Consistent with a recent finding that single-item QOL assessments detect a patient-perceived problem in peripheral neuropathy more than six weeks earlier than CTC (Morton et al, ASCO 2005) The multiple-item assessments are in better agreement with occurrence or CSD in AE compared to the Uniscale

52 The Visual Analogue Uniscale Please mark with an ‘X’ the appropriate place within the bar to indicate your rating of this person’s quality of life during the past week. Lowest quality applies to someone completely dependent physically on others, seriously impaired mentally, unaware of surroundings, and in a hopeless position. Highest quality applies to someone physically and mentally independent, communicating well with others, able to do most of the things enjoyed, pulling own weight, with a hopeful yet realistic attitude.

58 BackgroundBackground Some studies have suggested a psychosocial intervention has a positive effect on survival, while others have not demonstrated such an effect or suggested a negative effect on survival. (Spiegel, 1990; Goodwin NEJM 2001; Spiegel, Cancer, 2002) Some studies have suggested a psychosocial intervention has a positive effect on survival, while others have not demonstrated such an effect or suggested a negative effect on survival. (Spiegel, 1990; Goodwin NEJM 2001; Spiegel, Cancer, 2002) Most interventions are single - focus and have targeted mood (Fawzy, AGP,1993; Jacobsen JCO 2002; Kolden, Psycho-Onc. 2002) Most interventions are single - focus and have targeted mood (Fawzy, AGP,1993; Jacobsen JCO 2002; Kolden, Psycho-Onc. 2002) Some studies have suggested a psychosocial intervention has a positive effect on survival, while others have not demonstrated such an effect or suggested a negative effect on survival.

60 Study Schema Patients with Advanced Stage Disease scheduled to undergo radiation therapy R Arm A: Structured multi- disciplinary psychosocial intervention. 8 - 90 minute sessions over 4 weeks Arm B: Standard Care QOL assessed at baseline and week 4 (EOT) Stratification: tumor type, ECOG PS, age

61 Linear Analogue Self Assessment (LASA) items Profile of Mood States – Short Form (POMS) Symptom Distress Scale (SDS) FACIT – Spiritual Well-Being Secondary endpoint assessment tools

62 Which is the “real” symptom endpoint?

63 At week 4, overall QOL was 10 points higher in the intervention arm than in the standard care arm (80 versus 70 on the 100-point scale respectively, p=0.047). The treatment group improved 3.3 points from baseline, while the control group decreased 8.9 points on average, p=0.009. More than three times as many patients in the treatment group reported a 10-point improvement in QOL from baseline compared to the control group (30% versus 9%, p=0.004). Primary Result: Overall QOL at 4 weeks
