Comparisons of Radiographic and Clinical Definitions of Disease Progression in Pediatric Patients with Newly Diagnosed Intrinsic Diffuse Brainstem Gliomas (BSG) Treated on a PBTC Phase II trial of Tipifarnib and Radiation

TPS367 Background: Inhibitors of the programmed death-1 pathway (PD-1) are effective in clear cell renal cell cancer (ccRCC). Preclinical data and case reports suggest that denosumab, an inhibitor of Receptor Activator of Nuclear Factor κ-B Ligand (RANKL) signaling, could potentiate the anti-tumour effects of anti-PD1 inhibitors without overlapping toxicities. We aim to determine the activity and safety of combining denosumab and pembrolizumab in advanced ccRCC. Methods: This single arm, multi-center, phase II trial will recruit 70 participants with metastatic or unresectable ccRCC, progressing during or after treatment with vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitors, and with no prior treatment with immunotherapy or denosumab. Participants will receive pembrolizumab 200mg IV every 3 weeks plus denosumab 120mg SC on days 1, 8 and 22 and then every 3 weeks until disease progression, prohibitive toxicity or maximum treatment of 24 months. Response will be assessed at weeks 12, 18, 24, then every 12 weeks until disease progression. Bloods for translational studies are collected at baseline, week 6 and on disease progression. The primary endpoint is objective tumour response rate (OTRR) per RECIST 1.1. Secondary endpoints include OTRR per iRECIST, progression free survival (PFS), time to OTRR, time to first skeletal related event, adverse events, and frequency of treatment delays/discontinuations. Correlative studies will include identification of prognostic and/or predictive biomarkers relating to immune and RANKL signaling. A sample size of 70 provides 90% power with a 1-sided type 1 error rate of 10% to distinguish the observed OTRR (and PFS at 6 months) from an OTRR of 40% (worthy of pursuit) versus 25% (not worthy of pursuit). 15 sites are open across Australia. As of September 23, 2020, 40 patients have been recruited. Clinical trial information: NCT03280667 .

Introduction: Patients with newly diagnosed multiple myeloma (NDMM) who are ineligible for autologous stem cell transplant (ASCT) tend to have comorbidities and/or advanced age that make this subset of patients difficult to manage with current drug regimens. Methods: A comprehensive literature search of PubMed, Embase, Clinicaltrials.gov and Web of Science was performed from inception and completed on 07/17/2019. Studies focusing on efficacy and tolerability of 3-drug regimens in patients with NDMM were included for the review. Results: Out of 3579 studies, a total of 10 (08 phase II and 03 phase III) clinical trials in last ten years (2010-2019) using 3-drug regimens in NDMM elderly pts (893M/807F) ineligible for ASCT (determined by investigators) were selected. A total of 1703/1740 NDMM pts were evaluated. Proteasome inhibitors (PIs) such as carfilzomib (C), bortezomib (V) and ixazomib (I) showed promising results in elderly transplant-ineligible NDMM pts. CLARION trial (phase III, n=955) compared two PIs (C and V) with melphalan (M) and prednisone. There was no statistically significant difference in progression-free survival (PFS) between two groups (median: 22.3 vs 22.1 months; HR: 0.91; 95% CI, 0.75-1.10, p = 0.159) as well as overall survival (OS) (HR: 1.08; 95% CI: 0.82-1.43). Difference in the least square means of the HR-QoL (Health related- quality of life) was 4.99 (p<.0001) favoring C-group. M may not be an ideal drug to combine with carfilzomib in this setting given more AEs.(Facon et al 2019). V as 3-drug regimen in combination with lenalidomide (L) in 242 pts achieved statistically significant prolonged PFS (median 43 mo) and OS (median 75 mo) with great efficacy and acceptable risk-benefit profile. (Durie et al 2017; phase III). Multinational phase II trial (n=70) by Dimopoulos et al (2019) evaluated I, with different fixed doses of cyclophosphamide (Cy). Median duration was 19 cycles, indicating the long-term tolerability of regimen. With favorable toxicity profile and maintained QoL scores, trial concluded that this therapy is tolerable in elderly transplant-ineligible NDMM pts. Tuchman et al (2017) in phase II trial (n=14) investigated (V-Cy-d) and achieved ORR of 64%, with ≥VGPR of 57%. Low dose V showed great efficacy with M yielding ORR of 86% and VGPR or better of 49% in phase II trial (n=101) that also evaluated Cy as 3-drug combination but results were more productive with M with longer PFS and OS which reduced when impact of frailty was examined on outcomes. Since toxicity was higher with M, trial suggested that 2-drug combination should be preferred in elderly frail patients. (Larocca et al 2015). Efficacy was quite promising when Bringhen et al (2014) trialed C with Cy-d; 87% OS and 76% PFS at 1 y in phase II trial (n=58) with much favorable safety profile. Monoclonal antibodies (mAb) such as elotuzumab (E) and pembrolizumab (Pe) are also tested in elderly. First study conducted on NDMM pts using humanized mAb; E, in phase II trial (n=40) by Takezako et al (2017) attained primary endpoint of the study (ORR) of (88%) and VGPR or better of 45% in Japanese pts with tolerable toxicities in elderly. No subjects on this study experienced severe peripheral neuropathy. KEYNOTE-185; a phase III multinational trial by Usmani et al (2019) evaluated Pe with Ld in 151 pts. FDA halted this study due to unfavorable benefit-risk profile; 19 deaths, 6 due to disease progression (PD), and 13 due to treatment-related AEs. Median PFS and median OS were not reached in either group. Immunomodulators such as L achieved one of the longest PFS reported in a trial of transplant ineligible patients (35 mo) by using LVd regimen in phase II multicenter trial (n=50). (O'Donnell et al 2018) Alkylating agents like bendamustine (ben) and M have been tested in different novel regimens. Decreasing intensity and increasing duration of ben resulted in better outcomes in phase II trial (n=59) by Berdeja et al (2016) and can be given as first line treatment. Ben yielded great results with low dose dexa as compared to high dose achieving 92% ORR. Original regimen was effective but relatively more toxic. Incidence of herpes and neuropathy decreased dramatically with the treatment modifications. Conclusion: Three-drug regimens having PIs, mABs, immunomodulators and alkylating agents have shown desirable results in NDMM transplant (ASCT)-ineligible elderly patients and are likely the emerging standard of care for NDMM.

Abstract PURPOSE Anlotinib, an orally multi-target tyrosine kinase inhibitor, inhibits tumor angiogenic and proliferative signal pathways. We performed a phase II trial of anlotinib in combination with the STUPP regimen in patients with newly diagnosed glioblastoma multiforme（GBM）to determine whether the combination therapy would safely improve outcomes in this group of patients. An initial pilot study assessed interim safety and tolerability. METHODS AND MATERIALS Ten newly diagnosed GBM patients were included in this study. All patients received standard radiation of 60 Gy in 30 fractions starting within 4–6 weeks after surgery with concurrent TMZ (daily, 75 mg/m2) and anlotinib (8mg per day, from day 1 to 14, every 3 weeks). After a 4-week break, adjuvant therapy including 6 cycles of TMZ (150–200 mg/m², from day 1 to 5, every 4 weeks) and 8 cycles of anlotinib (8mg per day, from day 1 to 14, every 3 weeks) was given. For patients completing adjuvant therapy, anlotinib alone (8mg per day, from day 1 to 14, every 3 weeks) was administrated until disease progression. RESULTS All patients completed concurrent chemo-radiotherapy without interruption. One patient developed grade 3 weight loss at 56th week and grade 3 presumed radiation-induced cognitive disturbance at 60th week. Fatigue and hypertension were frequently observed during treatment, which potentially be related to the treatment. No severe toxicity was observed in other patients. Up to this writing, none of these patients developed disease progression. CONCLUSION Anlotinib combined with the STUPP regimen is a potential choice for newly diagnosed GBM patients. It is well tolerated and the toxicity is manageable. It’s acceptable to continue enrolling of this Phase II study.
