9 Background: The Z9001 study revealed adjuvant imatinib for 1 year significantly improved RFS in GIST patients (pts). The SSGXVIII study compared 3 years with 1 year of adjuvant imatinib for high risk GIST pts, but there was no study to evaluate shorter period of imatinib administration than 1 year. We conducted a randomized phase II study to compare 6 months (6-mo) with 12 months (12-mo) adjuvant imatinib for intermediate or high risk GIST pts. Methods: Inclusion criteria included ECOG-PS of 0 or 1, age between 20 and 79 years, and primary KIT-positive GIST with intermediate or high risk according to the Fletcher criteria. Pts were randomized assigned to the 6-mo or 12-mo treatment of imatinib 400 mg/day after complete resection. The primary endpoint was recurrence-free survival (RFS). The study was designed as a randomized screening trial to evaluate non-inferiority with margin of hazard ratio 1.67, 1-sided alpha 0.2 and power 0.8. Results: Ninety-two pts were randomly allocated the 6-mo group (n=45) or the 12-mo group (n=47) between Dec 2007 and Aug 2011, which was well balanced for baseline characteristics. One patient was ineligible due to non-GIST (desmoid) tumor at a central review. The proportions of pts completed their assigned adjuvant treatment were 80% in the 6-mo and 70% in the 12-mo group. The first interim analysis was conducted at Sep 2012 with the median follow-up time of 33 months. The 1- and 2-year RFS were 82% and 65% in the 6-mo group and 96% and 86% in the 12-mo group, respectively. Hazard ratio of recurrence was 1.81 (95%CI: 0.84-3.91), and the 2-sided log-rank p value was 0.12. Adjuvant imatinib was well tolerated, with one patient of Gr. 4 rash and no treatment-related death. Because of the lower efficacy of the 6-mo group than expected, the Data and Safety Monitoring Committee recommended the early release of first interim analysis results. Conclusions: Adjuvant Imatinib for 6-mo was inferior in efficacy to that for 12-mo in terms of RFS. Shortening of the adjuvant imatinib duration is not recommended for intermediate or high risk GIST pts. Clinical trial information: UMIN000000950.

128 Background: To report initial response, acute treatment-related toxicity and patient-reported quality of life (QoL) after 24Gy SDRT derived from a randomized Phase II study of patients with intermediate-risk adenocarcinoma of the prostate (NCCN definition). Methods: Between November 2015 and December 2016, 30 hormone-naïve patients were enrolled in an IRB-approved prospectively randomized phase II study to receive either 45Gy in 5 consecutive daily fractions (Hypo-SBRT) or 24Gy SDRT. Treatment was based on VMAT-IGRT with urethral sparing via a dose-painting technique and real-time motion management with beacon transponders. The PTV included the MR-delineated prostate gland and seminal vesicles with 2 mm margin. Precise PTV targeting and anatomical reproducibility was achieved via placement of an endorectal air-filled balloon (150 cc) and a Foley catheter. This setup also conferred organ motion mitigation, and online tracking ensured treatment delivery within the 2 mm PTV margin.. Genito-urinary (GU) and gastro-intestinal (GI) toxicity were graded according to the NCI CTCAE v.4, and QoL was assessed by EPIC and IPSS questionnaires. Tumor response was assessed biochemically (PSA) and by follow-up MRI at 3 months after treatment and at 6 months intervals thereafter. Results: With a median follow-up of 16 months (range, 11-24), no grade ≥2 acute GI or GU toxicities were observed in either group. There were no significant differences in mean EPIC scores in all domains. An initial 6% and 8% drop in the EPIC urinary domain score occurred in the hypo and SDRT arm respectively, returning to baselines by 3 months. . PSA reduction kinetics were similar between the two regimens, reaching ≤1 ng/mL by 18 months. Of note, all cases, regardless of treatment regimen, converted to non-detectable disease on MRI at 6 months. Patients in this trial will receive a planned 24 months post-treatment biopsy to validate treatment outcome. Conclusions: These early trial outcomes indicate that 24Gy SDRT can be consistently and safely delivered, yielding the same low acute toxicity as demonstrated with the hypo 5x9Gy schedule, and is associated with excellent QoL measures. Clinical trial information: NCT02570919.

2017 Background: The optimal use of bevacizumab (bev) in recurrent glioblastoma (GBM) remains uncertain including the choice between monotherapy or combination therapy as well as the role of continuing bev beyond disease progression. Methods: This was a sequential stratified two part randomized phase II study. Eligibility criteria included: recurrent GBM after radiotherapy and temozolomide, no other chemotherapy for GBM, ECOG PS 0-2. The primary objective (Part 1) was to determine the effect of bev plus carboplatin versus bev alone on 6 month progression-free survival (6PFS) using modified RANO criteria. Bev was given 2-weekly 10mg/kg, carboplatin 4-weekly AUC5. On progression, patients (pts) able to continue treatment were randomized to continue or cease bev (Part 2). Secondary endpoints included response rate (RR); cognitive function; quality of life; toxicity and overall survival (OS). Results: 122 pts (median age 55) were enrolled from 18 Australian sites. 87 (71.3%) were PS 0-1. The current median follow up is 14.7 months with median on-treatment time 3.7 months. 6PFS was 26% (combination) versus 24% (monotherapy) (HR 0.96, 95%CI (0.66, 1.39), p = 0.82). RR (CR+PR) was 15% versus 13%. Median OS was 6.9 versus 6.4 months (HR 1.08, 95%CI (0.74, 1.59), p = 0.68). There were 2 treatment (bev) related deaths in the combination arm (one GI perforation, one CNS hemorrhage). To date, overall incidence of bev-related AEs is similar to prior literature with 10 (8.3%) venous thromboembolic events and 5 (4.2%) hemorrhages (all grades) reported. There were 3 episodes of G3-4 neutropenia, all in the combination arm (5%) and 9 episodes of G3-4 thrombocytopenia. As of January 14, 2013, 47 pts have continued on to Part 2. Data for bev beyond progression is not yet available. Conclusions: In this study of patients with recurrent GBM, the addition of carboplatin to bev did not result in additional clinical benefit compared to bev monotherapy. This large multicentre population-based study demonstrated that clinical outcomes in patients with recurrent GBM treated with bev were inferior to previously reported studies. Ongoing follow-up of patients on bev beyond progression, and novel secondary and exploratory endpoints continues. Clinical trial information: ACTRN12610000915055.
