Abstract Abstract 1024 Background: The MMRC is a non-profit, disease-focused consortium founded in 2004. Sixteen North American member institutions with expertise in multiple myeloma (MM) work collaboratively with the MMRC Inc. (Norwalk, CT) and numerous pharmaceutical partners to speed development of new treatment options to MM patients. In December 2007, MMRC Inc. implemented business solutions to address barriers to rapid activation of phase I-II trials and established benchmarks for initiating and conducting these studies. In December 2010, we reported significantly faster trial start up and accrual data from previous years1,2. Today, we update and expand on MMRC performance data and analysis of progress. Methods: Twenty-five (25) trials conducted within the Consortium from May 2006 to July 2011 had sufficient start up trial data for review. FPFD was defined as the time from the member institutions' receipt of the final protocol (FP) from the trial sponsor, to the time the first patient was dosed on the trial at any participating MMRC member institution. With respect to enrollment, pre-study enrollment commitment (EC) established between MMRC and the study sponsor was defined as the total number of subjects committed to receive at least one dose of study drug across all participating MMRC centers on a trial; baseline enrollment timeline (BET) was prospectively defined as the target time period to attain EC. Results: Mean time to FPFD in the recent group of trials (RG; n=18; Sept 08-Jul 11) held steady at 131 calendar days from receipt of FP as compared to 181 days for the early group of trials (EG; n=7; Jun06-Sept08) representing a 28% reduction in time to FPFD. More importantly, there was a 20% decrease in time to FPFD by all participating MMRC centers on any MMRC trial from 189 days in the RG compared to 236 days in the EG representing an important achievement especially in the Phase I/II arena. MMRC trial accrual data was available for 17/25 trials (2 EG trials were missing data and 6 RG trials continue enrolling). The pre-study mean MMRC EC was 44 subjects per trial (n=19 trials; 849 patients); the mean actual MMRC enrollment was 49 subjects per trial (n=19; 935 patients through July 11) representing a 10% over enrollment versus committed enrollment. A total of 17/19 evaluable trials (89%) met their EC; 12/19 trials met EC within BET (71%) of which 8/12 trials (67%) reached EC 34% faster than their BET (representing a mean reduction of 4.5 months). The overall pre-study mean BET for 19 trials was 13.6 months. MMRC's actual mean enrollment timeline was 12.8 months for the group of 17 evaluable trials representing improvement over the original BET by a mean of 10%. Discussion: MMRC's acceleration of clinical trials provides physicians and patients with rapid access to novel compounds; industry with data for important drug development decisions; and academic institutions with more trials of high scientific interest. Even so, our data uncovered opportunities for improvement. The submission time from receipt of the final protocol from the trial sponsor to Scientific Review Committee (SRC) took an average 30 calendar days across all trials. A reduction to half this time could make a difference to patients and therefore warrants further exploration. Conclusion: Today, drug development in multiple myeloma is fast-paced and highly competitive. MMRC's frequent review of trial metrics provides valuable insight to continually speed answers to physicians, patients and industry.

Abstract Abstract 3803 Background: The MMRC is a non-profit, disease-focused consortium founded in 2004 comprised of 13 North American centers with expertise in multiple myeloma (MM). The MMRC Inc. (Norwalk, CT), MMRC's member institutions, and several pharmaceutical partners work closely to speed early development of new treatment options for MM patients. In December 2007, MMRC headquarters staff implemented multiple project management (PM) business solutions to address trial barriers that delay activation of our phase I-II clinical trials and established trial metric benchmarks considered attainable at our member institutions. In November 2009, we reported initial data1 on trial activation: MMRC trials initiated between Sep08-Jul09 (n=5) demonstrated a 38% decrease in mean time to first patient dosed (FPFD), compared with the Early Group trials (EG) initiated before PM solutions (Jun06-Sept08; n=7 trials). These results also confirmed improvement over published metrics from Dilts et al 2,3. We present additional data on time to FPFD and now enrollment, to assess impact of the MMRC PM resources and processes on trial efficiency. Methods: Twenty-one (21) trials conducted within the MMRC from May 2006 to June 2010 had sufficient trial data for review. Data were collected by MMRC-funded project managers at the clinical centers using a web-based clinical trial management system (CTMS). FPFD was defined as the time from the member institutions' receipt of the final protocol (FP) from the trial sponsor, to the time the first patient was dosed on the trial at any participating MMRC member institution. With respect to enrollment, pre-study enrollment commitment (EC) established between MMRC and the study sponsor was defined as the total number of subjects committed to receive at least one dose of study drug across all participating MMRC centers on a trial; baseline enrollment timeline (BET) was prospectively defined as the target time period to attain EC. Results: Mean time to FPFD was 181 calendar days for the early group trials (EG, n=7) and 122 days for the recent group (RG) trials (n=14, Sep08 – Jun10), representing a 32% reduction of time to FPFD in the RG. Additionally, time from final protocol to first patient dosed at all MMRC centers on a trial decreased 18% from a mean of 7.7 months (EG) to 6.3 months (RG). With respect to MMRC trial enrollment, data was available for 16/21 trials (5 EG and 11 RG). 2 EG trials were missing data and 3 RG trials were still enrolling as of June 2010. The mean MMRC pre-study EC was 39 subjects per trial (n=16 trials; 626 enrollment target); the mean actual MMRC enrollment was 49 subjects per trial (n=16; 783 enrolled through Jun 29, 2010) representing a 25% increase in actual versus committed enrollment. Two trials did not meet MMRC EC: MMRC investigators discontinued their involvement in these trials at approximately 30% target EC due to trial complexity or low patient enrollment. 14/16 evaluable trials (88%) met their EC; 11/16 trials met EC within BET (69%) of which 8/16 trials (50%) reached EC 34% faster than their BET (representing a mean reduction of 4.5 months). The overall pre-study mean BET for 16 trials was 13.1 months. MMRC's actual mean enrollment timeline was 11.3 months for the group of 14 evaluable trials representing improvement over the original BET by a mean of 1.9 months (14%). We believe FP to FPFD is a more meaningful metric beyond that of first patient consented. Moreover, we believe that if all participating trial centers focus their efforts on dosing the first patient and within a targeted timeframe, it may improve our research efforts overall. Conclusion: Development of drugs in the clinical setting has become time and resource intensive. Activating and enrolling trials promptly is a priority for drug development. The MMRC's standardization of processes and support for site-based PM resources results in improved trial metrics. MMRC member centers met or exceeded pre-specified enrollment targets in 88% of the trials analyzed to date. Ongoing monitoring of trial conduct continues to reveal areas where increased focus is needed to realize further trial efficiencies. These trial metrics and measures to improve efficiency may be applied with similar expected benefit in all oncology disciplines.

Abstract Abstract 1859 Genome wide RNA interference studies identified Aurora Kinase (AURK) A and B as lethal targets in Multiple Myeloma (MM) while suppression of these genes also sensitized MM to bortezomib (BTZ). MLN8237 is an oral inhibitor of AURKA. We therefore conducted a Phase I clinical trial of MLN8237 in combination with BTZ. The study enrolled a total of 19 patients at 5 institutions. 9 patients are still receiving active treatment as of the date of this report. Study Design: The phase I portion of this study uses a standard 3+3 design to determine the maximum tolerated dose (MTD) of MLN8237 and BTZ in patients with relapsed/refractory MM. Eligibility required a minimum of 1 and maximum of 4 lines of prior therapy. Patients who have received prior BTZ therapy were allowed on trial as long as they did not progress during prior BTZ or ≤ 60 days of therapy discontinuation. The following laboratory values were required £7 days prior to registration. ANC3 1000/mL, Hgb ≥9 g/dl, PLT3 100,000/mL, Total bilirubin £1.5 × upper limit of normal (ULN), Creatinine £ 2.5 × ULN, a baseline LVEF ≥45%. Patients were required to be able to take oral medication and to maintain a fast as required for 2 hours before and 1 hour after MLN8237 administration. Treatment Overview: The first 3 patients received MLN8237 at 25 mg po days 1–14 and BTZ at 1.3 mg/m2/dose iv. days 1, 4, 8, 11 on a 28 day schedule. Based on data from other concurrent trials an amendment changed dosing of MLN8237 to 20, 30, 40 or 50 mg po twice daily on days 1–7 and BTZ was given at 1.5mg/m2 iv weekly on a 28 day schedule. Results: Median age of patients was 64, 63% were male, 31% had high risk genetics, 84% had prior stem cell transplant, 53% of patients were relapsed and 47% were relapsed and refractory to therapy. No DLTs were observed even at the highest dose level tested. However, one patient at the highest dose level required a platelet transfusion in order to initiate treatment on time in Cycle 2. Thus, a further 3 patients accrued at the highest dose level before declaring the MTD and proceeding to phase II. The highest dose level (Dose Level 3: MLN8237 50 mg po twice daily on days 1–7; BTZ 1.5 mg/m2 iv. given on days 1, 8, 15, 22) was the final dose level tested (the MTD of single agent MLN8237 is 50mg as defined in other Phase I trials). The ORR was 26% (1 CR, 4 PR); when minor responses are included the ORR was 52%. Median follow up was 4.3 months (range 0.9–23.4) and PFS was 5.5 months. At last follow up 12 patients showed no progression and 7 had progressed. Toxicity: 63% of patients experienced a grade 3AE and 5% a grade 4 AE. Grade 3 or 4 toxicity seen in more than one patient was all hematologic with thrombocytopenia and neutropenia being common. Other toxicity of any grade regardless of attribution occurring in more than 20% of patients included neuropathy 63%, fatigue 63%, diarrhea 53%, nausea 47%,vomiting 26%, infection 32%, alopecia 21%, Conclusions: The MTD of the combination is MLN8237 50 mg po twice daily on days 1–7 and BTZ at 1.5mg/m2 iv weekly. Phase II testing is underway and updated results will be presented. Disclosures: Stewart: Millenium: Consultancy, Honoraria, Research Funding; Onyx: Consultancy; Celgene: Consultancy.
