    Abstract: 3009 Background: Aurora kinases A, B, and, C play essential roles in regulating cell division. Overexpression of aurora A and B in human tumors is associated with high proliferation rates and poor prognosis. AMG 900 is an investigational, orally administered, highly selective inhibitor of aurora A, B, and C that demonstrated activity in drug-resistant cell lines and human tumor xenografts. This study evaluated the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics of AMG 900. Methods: Key eligibility criteria: ≥ 18 years old, advanced solid tumors, measurable disease, ECOG ≤ 2, and adequate organ function. AMG 900 was administered orally daily for 4 consecutive days (D) every 2 weeks (Q2W). In the dose-escalation phase, the starting dose was 1 mg and was escalated by 100% in subsequent cohorts (1 pt/cohort) until dose limiting toxicity (DLT) or grade 2 (G2) AMG 900-related toxicity occurred in the first 28 D. Dose escalation continued in a standard 3+3 design at ≤ 25% if DLT occurred or ≤ 50% if G2 related toxicity occurred. The maximum tolerated dose (MTD) was determined without prophylactic G-CSF support. Results: As of OCT 2011, 19 pts (1 pt at 1, 2, 4, and 8 mg; 3 pts at 16 mg; and 6 pts at 24 and 30 mg) had received ≥ 1 dose of AMG 900. Demographics were 58% women, median age 60 (32-77) years, and ECOG 0/1, 63%/37%. There were 4 DLTs: G4 neutropenia 〉 7 days at 24 mg (n=1) and 30 mg (n=1); G4 neutropenia 〉 7 days + G4 thrombocytopenia at 30 mg (n=1); and febrile neutropenia (FN) at 30 mg (n=1). MTD without G-CSF support was 24 mg. 89% of pts had treatment-related adverse events (AEs). G≥3 treatment-related AEs were neutropenia, 8 (42%); leukopenia, 4 (21%); anemia, 2 (11%); thrombocytopenia, 1 (5%); and FN, 1 (5%). Preliminary PK showed no obvious departures from dose-proportionality with a half-life of ~16 h. Tumor-response data were available for 17 pts: stable disease, 13 pts (range 0.4 to 43.7 wks); progressive disease, 4 pts. One pt (16 mg cohort) with recurrent ovarian cancer had 16% tumor shrinkage and 45% decrease in CA-125 (SD 〉 6 months). Conclusions: AMG 900 administered at 24 mg daily for 4D Q2W is the recommended dose for phase 2 trials. Dose escalation is now ongoing to determine the MTD with prophylactic G-CSF.

    Abstract: 2578 Background: CZ48, the 20-O-propionate ester of camptothecin (CPT), is a prodrug of CPT first described by Cao et al. in 1998. The side-chain is enzymatically cleaved in tissues. This gives rise to CPT, a potent inhibitor of topoisomerase I. Methods: An open-label, single-arm, dose-escalation Phase I study was performed to determine the maximum tolerated dose (MTD) of CZ48 in patients with advanced solid tumors. Initial dosing started qd po 80mg/m 2 , advancing to 2560mg/m 2 for 21 consecutive days, followed by 7 days rest. Dosing was restarted in cohorts of 3 patients tid po at 18mg/m 2 and escalated to 1g/m 2 on a 5 days on, 2 days off schedule for 28 days. Patients were prescreened by measuring CPT levels in plasma following a single pilot dose of CZ48. Dose was doubled until occurrence of at least Grade 2 adverse event, at which time 3+3 patient cohorts with a dose escalation of 33%-100% were implemented. DLT in 2/6 patients defined the MTD as the preceding DLT dose. PK parameters were measured prior to dosing, days 1-5, and day 28 of Cycle 1. Results: Poor absorption led to initial qd dosing reaching 2560mg/m 2 with no signs of DLT. Subsequent tid dosing showed improved plasma levels and arrival at DLT. 34 patients were treated across 8 dose levels from 18 to 1000 mg/m2. The most frequent study-related adverse effects were cystitis, vomiting, diarrhea and fatigue. Grade IV toxicities observed were febrile neutropenia, anemia, and thrombocytopenia. Preliminary PK data in the qd dosing showed poor correlation between dose and C max or AUC, while PK in tid patients showed slightly improved correlation between dose and both CZ48 AUC (Pearson's correlation coefficient ϱ=0.476, p 〈 0.01) and CZ48 C max (ϱ =0.51, p 〈 0.01). Evidence of clinical activity with stable disease ≥ 6 months was observed in 2 heavily pre-treated colon and one breast cancer patient. Conclusions: The MTD of tid po CZ48 administered 5 days on, 2 days off of 28-day cycle is between 750 mg/m 2 and 576 mg/m 2 . Overall toxicity is relatively mild, with DLT being cystitis and myelosuppression. Even with tid dosing, PK values correlate poorly to dose. A new formulation with 3-5 fold higher preclinical absorption values is being considered for introduction into the trial. Clinical trial information: NCT00947739.

    Abstract: This open-label, phase I, dose-escalation study assessed the maximum-tolerated dose (MTD), safety, pharmacokinetics, and antitumor activity of sunitinib in combination with capecitabine in patients with advanced solid tumors. Patients and Methods Sunitinib (25, 37.5, or 50 mg) was administered orally once daily on three dosing schedules: 4 weeks on treatment, 2 weeks off treatment (Schedule 4/2); 2 weeks on treatment, 1 week off treatment (Schedule 2/1); and continuous daily dosing (CDD schedule). Capecitabine (825, 1,000, or 1,250 mg/m 2 ) was administered orally twice daily on days 1 to 14 every 3 weeks for all patients. Sunitinib and capecitabine doses were escalated in serial patient cohorts. Results Seventy-three patients were treated. Grade 3 adverse events included abdominal pain, mucosal inflammation, fatigue, neutropenia, and hand-foot syndrome. The MTD for Schedule 4/2 and the CDD schedule was sunitinib 37.5 mg/d plus capecitabine 1,000 mg/m 2 twice per day; the MTD for Schedule 2/1 was sunitinib 50 mg/d plus capecitabine 1,000 mg/m 2 twice per day. There were no clinically significant pharmacokinetic drug-drug interactions. Nine partial responses were confirmed in patients with pancreatic cancer (n = 3) and breast, thyroid, neuroendocrine, bladder, and colorectal cancer, and cholangiocarcinoma (each n = 1). Conclusion The combination of sunitinib and capecitabine resulted in an acceptable safety profile in patients with advanced solid tumors. Further evaluation of sunitinib in combination with capecitabine may be undertaken using the MTD for any of the three treatment schedules.

    Abstract: CMB305 is a heterologous prime-boost vaccination regimen created to prime NY-ESO-1–specific CD8 T-cell populations and then activate the immune response with a potent TLR-4 agonist. This open-label randomized phase II trial was designed to investigate the efficacy and safety of adding the CMB305 regimen to atezolizumab (anti–programmed death ligand-1 therapy) in comparison with atezolizumab alone in patients with synovial sarcoma or myxoid liposarcoma. PATIENTS AND METHODS Patients with locally advanced, relapsed, or metastatic synovial sarcoma or myxoid liposarcoma (any grade) were randomly assigned to receive CMB305 with atezolizumab (experimental arm) or atezolizumab alone (control arm). The primary end points were progression-free survival (PFS) and overall survival (OS) analyzed using the Kaplan-Meier method. Safety and immune responses were assessed. RESULTS A total of 89 patients were enrolled; 55.1% had received ≥ 2 prior lines of chemotherapy. Median PFS was 2.6 months and 1.6 months in the combination and control arms, respectively (hazard ratio, 0.9; 95% CI, 0.6 to 1.3). Median OS was 18 months in both treatment arms. Patients treated with combination therapy had a significantly higher rate of treatment-induced NY-ESO-1–specific T cells ( P = .01) and NY-ESO-1–specific antibody responses ( P 〈 .0001). In a post hoc analysis of all dosed patients, OS was longer (36 months) in the subset who developed anti-NY-ESO-1 T-cell immune response (hazard ratio, 0.3; P = .02). CONCLUSION Although the combination of CMB305 and atezolizumab did not result in significant increases in PFS or OS compared with atezolizumab alone, some patients demonstrated evidence of an anti-NY-ESO-1 immune response and appeared to fare better by imaging than those without such an immune response. Combining prime-boost vaccines such as CMB305 with anti–programmed death ligand-1 therapies merits further evaluation in other clinical contexts.

    Abstract: Avelumab, an antiprogrammed death ligand-1 antibody, is approved as a monotherapy for treatment of metastatic Merkel cell carcinoma and advanced urothelial carcinoma, and in combination with axitinib for advanced renal cell carcinoma. We report the efficacy and safety of first-line avelumab in advanced non-small cell lung cancer (NSCLC). Methods In a phase I expansion cohort of the JAVELIN Solid Tumor trial, patients with treatment-naive, metastatic, or recurrent NSCLC received 10 mg/kg avelumab intravenously every 2 weeks. Endpoints included best overall response, duration of response (DOR), progression-free survival (PFS), overall survival (OS), and safety. Results Overall, 156 patients were enrolled and treated. Median duration of follow-up was 18.6 months (range, 15 to 23 months). The objective response rate was 19.9% (95% CI, 13.9 to 27.0), including complete response in 3 (1.9%) and partial response in 28 (17.9%). Median DOR was 12.0 months (95% CI, 6.9 to not estimable). Median PFS was 4.0 months (95% CI, 2.7 to 5.4) and the 6-month PFS rate was 38.5% (95% CI, 30.7 to 46.3). Median OS was 14.1 months (95% CI, 11.3 to 16.9) and the 12-month OS rate was 56.6% (95% CI, 48.2 to 64.1). Treatment-related adverse events (TRAEs) occurred in 107 patients (68.6%), including grade ≥3 TRAEs in 19 (12.2%). Immune-related adverse events and infusion-related reactions occurred in 31 (19.9%) and 40 patients (25.6%), respectively. No treatment-related deaths occurred. Conclusion Avelumab showed antitumor activity with a tolerable safety profile as a first-line treatment in patients with advanced NSCLC. These data support further investigation of avelumab in the phase III JAVELIN Lung 100 study. Trial registration details ClinicalTrials.gov NCT01772004 ; registered January 21, 2013.

    Abstract: Background: Translation of basic discoveries to clinical care for patients with cancer is a difficult process greatly enabled by physician-trained researchers. Three categories of physicians, with responsibilities spanning from laboratory and preclinical research to direct patient care, are involved in the translational research continuum: physician-scientist (PS), clinician investigator (CI), and academic clinician (AC). Methods: To define how protected time for research efforts is supported, the Association of American Cancer Institutes (AACI) conducted a survey of their member institutions, obtaining 56 responses documenting time spent in research and clinical activities across multiple cancer disciplines, and providing information about funding streams for the different categories of cancer physicians. Results: Responses showed that PSs and ACs are minimally involved in clinical research activities; the driver or clinical research in academic cancer centers is the CI. A significant concern was a lack of stable funding streams for nonbillable clinical research activities, putting the sustainability of the CI in jeopardy. Limited funding was derived from hospital sources, with most support derived from cancer center sources. Conclusions: This study highlights the importance of the CI in translational cancer medicine and represents a call to action for institutions and research funding agencies to develop new programs targeted toward CI support to ensure continued progress against cancer.

    Abstract: 11030 Background: In 2020, the NCI funded a new educational consortium, NASDC (NCI Awardee Skills Development Consortium, RFA-CA-19-010 and -011), through four institutionally granted UE5 awards to deliver a specific course each and a U24 award as a Coordinating Center. The goal is to teach current early-career faculty NCI grantees skills in areas critical for successful independent academic cancer research careers. Courses focus on leadership and socioemotional skills, health disparities, immuno-oncology, and cell and gene therapy. Teaching will initially be virtual, given the COVID pandemic. Methods: A steering committee and four working groups were established to build the consortium infrastructure, including the NASDC (osu.edu) website. Clientele are early-career faculty PD/PI of a current NCI-funded grant (K01, K07, K08, K22, K23, K25, R00, R21, DP1, DP2, DP5, R01, R23, R29, R37, R56, RF1, RL1, U01), of whom 454 were directly contacted. Blast emails and social media were also used. We are reporting the characteristics of 154 applicants, who completed the RedCap application online. Results: 85% of the applicants are within the first 5 years of a faculty appointment, 87% at the assistant professor rank, and 65% on tenure track. 40% hold an M.D. degree and 72% a Ph.D. 81% are US citizens, 52% females, and 45/33/16/2/4%-11% are White/Asian/Black/Native Americans/Other–Hispanics/Latino. 76% work at NCI-designated comprehensive cancer centers. Mean protected research time is 80%. Non-mutually exclusive fields of research interest are therapeutics (46%), basic science (37%), disparities (34%) prevention (32%), public health (28%), and pediatrics (10%). 66% have received a K-award grant, 13% each an R21 or R00, and 3% an R01. Additionally, 35% had a second NCI grant as PI, 10% a third grant, and 60% had non-NCI grants. Reasons for applying included (1) not quite ready to lead a research team (42%), (2) need for stronger career mentoring (37%), and (3) not being fully confident in research skills (21%). Conclusions: Applicants to the new NCI educational consortium (NASDC) have a successful start to their academic career with a third having obtained more than one NCI award. Most applicants work at NCI-designated comprehensive cancer centers. As cancer research continues to evolve and has the potential to address critical health care needs of the nation, NASDC will strive to equip scientists to be leaders, teach advances in technology, and impart confidence in research skills.
