NHMRC Clinical Trials Centre ANZGOG AGM, 2 April 2009, Noosa NHMRC Clinical Trials Centre Symptom Benefit Study Measuring the Benefit of Palliative Chemotherapy in women with platinum refractory/ resistant ovarian cancer ANZGOG – 0701
2
NHMRC Clinical Trials Centre ANZGOG AGM, 2 April 2009, Noosa NHMRC Clinical Trials Centre Study Background The aim is to develop a method to measure the benefit of chemotherapy, which takes into account BOTH subjective and objective responses Document time to symptom progression as an additional endpoint as well as symptom benefit Better insight into patterns of care and reasons for treatment with platinum resistant or refractory ovarian cancer Develop a prognostic index that better defines outcomes and test in a separate group
3
NHMRC Clinical Trials Centre ANZGOG AGM, 2 April 2009, Noosa NHMRC Clinical Trials Centre Objective Stage 1: To determine the symptoms and aspects of HRQL that are rated most severe, troublesome in patients and identify best instruments to use in stage 2 Stage 2: To determine the proportion of women benefiting from palliative chemotherapy as defined by a clinically significant improvement in HRQL scores and improvement of symptoms and time to symptom progression.

ANZGOG AGM, Noosa 2 April 2009 NHMRC Clinical Trials Centre Ovarian Symptom Benefit Study (OSBS) Initial results and rationale for choosing the FACT-O and revising the Patient DATA Form – Ovarian as the patient reported outcome measures (PRO) for stage 2 Prepared by Madeleine King and Martin Stockler on behalf of the Ovarian Symptom Benefit Study Team 6 October 2009
21
ANZGOG AGM, Noosa 2 April 2009 NHMRC Clinical Trials Centre Background: What’s the problem? OSBS stage 1 uses 4 questionnaires to measure symptoms and/or quality of life: items 1.Symptom Representation Questionnaire (SRQ)66 2.Pt Disease & Treatment Assessment (Pt DATA Form) 48 3.FACT-O (including 8 items of FOSI)39 4.QLQ-C30 + Ov28 58 The booklet was deliberately long and repetitive to corroborate findings and help determine the best subset of items for future studies Interviews with 10 patients indicated that they neither preferred nor disliked any particular questionnaires
22
ANZGOG AGM, Noosa 2 April 2009 NHMRC Clinical Trials Centre Substitutability of candidate questionnaires SRQ vs. Patient DATA Form –designed to measure clinically important aspects of QOL –similar layouts, 0 to 10 scales –single-item scoring (rather than multi-item or domain scoring) QLQ-C30/Ov28 vs. FACT-O –designed to measure quality of life (QOL) in cancer clinical trials –similar format and layout, similar response scales –multi-item domains & scoring (QLQ-C30 incl. some single items) We decided to choose for OSBS stage 2 –Either SRQ or Pt-DATA Form for individual symptoms –Either QLQ-C30/Ov28 or FACT-O for multi-dimensional QOL
23
ANZGOG AGM, Noosa 2 April 2009 NHMRC Clinical Trials Centre ‘First filter’ analysis: aims & methods Aim D etermine which 4 PRO questionnaires to retain for stage 2 Analysis 1.Prevalence of each possible symptom in the ‘Top Three Most Noticed Symptoms in the last week’ (as asked by the Symptom Representation Questionnaire). 2.Summary statistics and histograms describing the frequency distributions of items and domain scores for each symptom at baseline 3.Changes from baseline in item and domain scores Data 31 patients who completed QOL questionnaires at baseline (pre-C1) AND (pre-C2 (AND/OR) pre-C3) by Jul ‘09

27
ANZGOG AGM, Noosa 2 April 2009 NHMRC Clinical Trials Centre Results at baseline (pre-cycle 1) For each of the top 10 symptoms: –we compared distributions and summary statistics for similar items –No major ceiling or floor effects –Similar distributions for similar items Nothing to choose between questionnaires
28
ANZGOG AGM, Noosa 2 April 2009 NHMRC Clinical Trials Centre Change at Cycles 2 and 3 For each of the top 10 symptoms: –we compared distributions and summary statistics of change scores on similar items –Mean change ~0 with large SD reflecting improvements in some women and deteriorations in others –Comparable results across q’aires Nothing to choose between questionnaires
29
ANZGOG AGM, Noosa 2 April 2009 NHMRC Clinical Trials Centre Decisions Retain modified Pt DATA Form – Ovarian to measure key symptoms Enhance coverage of the Top 10 Allow measurement of both current status and change Modifications by developer and OSBS investigators OSBS Recent Status Form (after each cycle) OSBS Change Form(after every 2 nd cycle) Develop a separate Side Effects Form for net clinical benefit Retain FACT-O (including FOSI) to measure QOL FACT-O Has fewer items: 39 (incl. 8 for FOSI) vs. 58 in the QLQ- C30/Ov28 Provides summary scores: overall QOL, Trial Outcome Index, FOSI Overall QOL based on all items QLQ-C30 22 sub scales Duplication of single-item symptoms with Pt DATA Form Global QOL based on 2 items
