A sample size of 270 (180 patients in the rigosertib group and 90 patients in BSC group), after 223 events (deaths) yields >90% statistical power to detect a significant difference in overall survival between the two groups. The trial is also well powered for other clinically relevant benefits of rigosertib over BSC.

Recombinant Erythropoietin Two recombinant human erythropoietins are available in the US: Erythropoietin and Darbepoetin Patients with lower-risk MDS without ring sideroblasts had a higher probability of response Responses in RARS no different than placebo

 


Erythropoietin in combination with other growth factors A Nordic phase II study showed that the addition of G-CSF could induce erythroid responses in patients resistant to Epo, especially those with RARS A US phase II study showed that patients responding to the combination could lose their response when G-CSF was withdrawn, and regain it when G-CSF was reintroduced Best Practice & Res Clin Haemato (2013) 1

 


Erythropoietin in MDS Mean response rate: 16% to 20% Predictors for good response were serum EPO level < 500 U/L and lack of previous need for transfusion Most responses to ESA occur within 8 weeks of treatment, some patients respond after 12 weeks Ludwig H.

 Twenty-two pts with MDS or AML who had failed treatment with hypomethylating agents were treated with rigosertib Study cohort comprised patients with a diagnosis of Intermediate-2 MDS (2 pts) High-risk MDS (6 pts) Chronic myelomonocytic leukemia (1 pt) AML (13 pts) Rigosertib in Patients with MDS or AML Relapsed or Refractory to a Hypomethylating Agent A Phase I/II Study Mount Sinai 04-05 Navada et al ASH abstr527 Blood 122:21 2013

 


 Responses according to IWG 2006 criteria observed in the BM and peripheral blood: Marrow Complete Response (4) Survival of these pts was 12, 15.7, 16.4, and 19.5 months Hematologic improvement (HI) (2); erythroid (1) platelet (1) An additional 2 pts had a >50% BM blast decrease from baseline but not to < 5% 10/19 evaluable pts (53%) demonstrated a bone marrow/peripheral blood response (6) or stable disease (4) Rigosertib in Patients with MDS or AML Relapsed or Refractory to a Hypomethylating Agent A Phase I/II Study Mount Sinai 04-05 Navada et al ASH abstr527 Blood 122:21 2013

 


 Early bone marrow response at 4-8 weeks correlates with improvement in overall survival Patients who did have a marrow complete or partial response responded early with a median time to response of 2-4 cycles Less than 20% blasts at study entry was a positive predictor of response (p=0.047). All 8 MDS pts in the study had <20%. Patients with proliferative disease with rapidly rising or high white blood cell counts did not respond Age, cytogenetic profile, prior response to hypomethylating agents were not predictors of response Rigosertib in Patients with MDS or AML Relapsed or Refractory to a Hypomethylating Agent A Phase I/II Study Mount Sinai 04-05 Navada et al ASH abstr527 Blood 122:21 2013

 


 Rigosertib has biologic activity with reduction in BM blasts associated with increased survival and improvement in peripheral blood counts in a subset of patients with MDS and AML who failed prior treatment with hypomethylating agents Patients with <20% blasts at study entry have a greater likelihood of response to rigosertib Early bone marrow response at 4-8 weeks in patients treated with rigosertib correlates with improvement in overall survival Combination studies with other agents, such as azacitidine, are ongoing Rigosertib in Patients with MDS or AML Relapsed or Refractory to a Hypomethylating Agent A Phase I/II Study Mount Sinai 04-05 Navada et al ASH abstr527 Blood 122:21 2013

1977 Clinical Trials Groups EORTC, Amsterdam began Quality of Life Committee - Aronson, QOL outcomes of trials (EORTC-QOL) CALGB, added Psychiatry Committee and we conducted the first clinical trials which measured “subjective improvement” as an outcome variable Cella, developed FACT (Functional Assessment for Cancer Therapy) scales for US trials

 


Psycho-Oncology in First Cancer Center Since 1977 Major research effort: to develop quantitative measurement of subjective symptoms with scales that were validated and reliable 2000 - evidence-based psychotropic and psycho through interventions

 


1980s - 90s Greater concern for ethics of Clinical trials Quality of consent to be informed Presented in patient non-terms Patient-centered “Humanistic” medicine

 


Health-related Quality of life (HRQOL) Assessment is more appropriately called Functional Assessment in all areas of living Cella, US and Aronson, EORTC Physical Social Sexual Psychological work

 


Health Related Quality of Life (HRQOL) “Extent to which one’s usual or expected physical, emotional, and social well being are affected by a medical condition or its treatment” Cella, 1994

 


EORTC and FACT Scales Have a core of questions common to function A module is added to assess function related to a particular organ / site (eg. prostate, breast)

 


Basic to Psycho-Oncology Research Developed validated quantitative measures of subjective dimensions QOL (Cella) Core and disease specific modules Pain Fatigue Distress Anxiety Depression Delirium

Recent Changes in Cooperative Trials Increasing use of directly using patients own symptom and side effects report, called Patient Report Outcomes (PROs) Patients participate in development of trials (Basch, CALGB/Alliance)

 


To Develop a specific QOL Assessment Literature search to identify primary toxicities expected Qualitative interviews with expert clinicians, patients receiving the treatment; traumatic content; analysis of common side-effects Collect poll of candidate items-related for importance reduce to most endorsed Pilot with patients for clarity, feed back, translatiblity and reading
