Abstract INTRODUCTION Despite advances in treatment modalities, the overall prognosis of GBM remains dismal, particularly for patients with unmethylated MGMT promoter. Thus, alternative treatment strategies are warranted. Our group has previously shown that addition of Sunitinib (SU11248) to standard therapy significantly improved the response of unmethylated MGMT cells through decreased angiogenicity and tumorigenicity. In this phase II trial, we tested for the first time the combination of Sunitinib with RT and Temozolomide in newly diagnosed MGMT unmethylated GBM patients. METHODS Patients with histologically confirmed WHO Grade IV GBM and MS-PCR confirmed unmethylated MGMT promoter, age 18-70, KPS ≥70, life expectancy ≥6 months were eligible. 41 patients treated between 2012 and 2017 were screened, 37 of which were eligible. Patients received 12.5 mg of daily Sunitinib for 7 days, followed by concurrent RT, Temozolomide and 12.5 mg Sunitinib for 6 weeks, then adjuvant Temozolomide x6 cycles. RT and Temozolomide doses were as per standard of care. Primary objective was PFS as assessed by RANO criteria, secondary objectives were OS and safety. RESULTS Median follow-up time was 15 months. Median PFS was 7 months (95%CI, 6.7-7.2) and 6-month PFS was 59.3%. Median OS was 13 months (95%CI, 12.62-13.37) and 2-year OS was 17.8%. Two patients had OS >50 months, with one surviving 71 months. Having received >3 cycles of adjuvant Temozolomide, surgery at progression or age ≤65 significantly predicted for better OS, with hazard ratios of 0.184 (p=0.001), 0.402 (p=0.026) and 10.017 (for age >65, p=0.002) respectively. Grade ≥3 thrombocytopenia occurred in 18.9% of patients, grade ≥3 neutropenia in 10.8% and grade ≥3 thromboembolic events in 13.5%. There were no grade 5 evens. CONCLUSION Addition of Sunitinib to RT and Temozolomide was well tolerated and survival outcomes compared favorably to the current standard of care for GBM patients with unmethylated MGMT promoter status.

Objective: To determine morphological and biological control as well as toxicity and quality of life (QoL) of men with localized prostate cancer (PCa) treated with MRI-guided focal boost radiotherapy. Material and Methods: 30 patients with PCa and a visible dominant intraprostatic lesion (DIL) identified on mpMRI were included in a prospective Phase II trial. Matching point registration of planning CT and T2W, diffusion-weighted and a gradient-recalled echo (GRE) MRI images made in treatment position was used for prostate and tumour delineation. Treatment consisted on 35 daily fractions of 2.17 Gy with a concomitant focal boost to the DIL of 2.43 Gy using volumetric modulated arc therapy (VMAT) and image-guided radiation therapy (IGRT) with intraprostatic fiducial markers. Biochemical failure was analysed using PSA nadir +2 ng/mL criteria and local control using mpMRI evaluation at 6–9 months following RT. Acute and late toxicity were defined according to CTCAE v.4.0 and RTOG/EORTC scales and QoL was assessed using IPSS, EPIC short-form and UCLA-PCI questionnaires. Results: The median radiation dose to the prostate was 77.6 Gy (IQR 77.3–78.1), and to the DIL was 85.5 Gy (IQR 85.0–86.0). With a median follow up of 30.0 months (IQR 25.5–40.27), all patients remain free of biochemical relapse. An mpMRI complete response was observed in 25 patients during the first post-treatment evaluation at 6 months. The remaining five patients achieved a complete disappearance of the DIL both on T2 and DWI on the second mpMRI performed at 9 months following treatment. Six out of 30 (20%) patients presented acute Grade 2 urinary toxicity with no Grade 3 acute complications. Acute rectal toxicity was only found in 2 (6.6%) patients (both Grade 1). Only late Grade 1 urinary and rectal complications were observed in 3/30 patients, respectively, with no Grade 2 or more late toxicity. The urinary, bowel and sexual bother EPIC scores were slightly and insignificantly increased in the first 3 months post-treatment, returning to normal afterwards. Conclusions: mpMRI-guided focal boost using VMAT hypofractionated technique is associated with an excellent morphological and functional response control and a safe toxicity profile. Advances in knowledge: In the present trial, we examined the potential role of mpMRI for radiological assessment (functional and morphological) of treatment response in high-risk prostate cancer patients treated with MRI-guided focal radiotherapy dose intensification to dominant Intraprostatic lesion.

Aim: Evaluate the utility of glutamate dehydrogenase (GLDH) and cardiac troponin I as safety biomarkers, and creatine kinase and muscle injury panel as muscle health biomarkers in Duchenne muscular dystrophy. Patients & methods: Data were collected during a Phase II trial of domagrozumab. Results: GLDH was a more specific biomarker for liver injury than alanine aminotransferase. Cardiac troponin I elevations were variable and not sustained, limiting its applicability as a biomarker. Muscle injury panel biomarkers were no more informative than creatine kinase as a muscle health biomarker. Conclusion: Results support the use of GLDH as a specific biomarker for liver injury in patients with Duchenne muscular dystrophy. Clinical trial registration: ClinicalTrials.gov , NCT02310763 .

We hypothesized that combining adoptively transferred autologous T cells with a cancer vaccine strategy would enhance therapeutic efficacy by adding anti-myeloma idiotype-keyhole limpet hemocyanin (Id-KLH) vaccine to vaccine-specific co-stimulated T cells. In this randomized, phase II trial, eligible patients received either the control (KLH only) or Id-KLH vaccine, an auto-transplant, vaccine-specific co-stimulated T-cells expanded ex-vivo, and two booster doses of the assigned vaccine. In 36 patients (20 in KLH, 16 in Id-KLH) enrolled, no dose-limiting toxicity was seen in either arm. At last evaluation, 6 (30%) and 8 (50%) had achieved complete remission in KLH-only and Id-KLH, respectively (p=0.22) and no difference in 3-year progression-free survival was observed (59% and 56%, respectively; p=0.32). In a 594 Nanostring nCounter gene panel analyzed for immune reconstitution (IR), compared with KLH-only patients, there was a greater change in IR genes in T-cells in Id-KLH patients relative to baseline. Specifically, upregulation of genes associated with activation, induction of effector function, and generation of memory CD8+ T cells after Id-KLH, but not after KLH control vaccination, was observed. Similarly, responding patients across both arms were associated with upregulation of genes associated with T-cell activation. At baseline, all patients had greater expression of CD8+ T-cell exhaustion markers. These changes were associated with functional Id-specific immune responses in a subset of Id-KLH patients analyzed. In conclusion, in this combination immunotherapy approach, we observed a significantly more robust IR in CD4+ and CD8+ T cells in the Id-KLH arm, supporting further investigation of vaccine and adoptive immunotherapy strategies.
