    Abstract: 152 Background: Prostate cancer (PC) is considered an immunologically ‘cold’ tumor and therefore patients are generally not considered good candidates for immunotherapy. Tumors arising in germline (g) BRCA1/2 mutation carriers are associated with higher genomic instability and levels of immune infiltration in breast and ovarian cancer. We investigated how germline mutations in DNA repair genes affect the tumor immune microenvironment (TME) of PC. Methods: Archival primary tumor samples from 26 patients with g BRCA2 mutations, 5 with g BRCA1, 5 with mutations in other DNA repair genes ( ATM, CHEK2, FANCI, PALB2 or BRCA2+ MSH2), and 26 sporadic patients were analyzed. OPAL multiplex immunohistochemistry was used to detect 7 markers (CD3, CD4, CD8, FOXP3, PDL1, AMACR, DAPI) to identify immune subsets and provide the X,Y coordinates of single cells. We developed novel computational distance-based methods to characterize the spatial distribution of cells. Gene expression was evaluated with the Nanostring panel of 770 immune genes. Results: g BRCA1/2 carriers showed lower levels of T cells (9.73% of the tumor stroma) compared to sporadic tumors (14.8%). In in both cothors the T cell population was dominated by CD4+ cells (69.5%), with CD8+ cells representing only 25.6%. Sporadic PCs displayed aggregation of T cells into large clusters in the stroma dominated by CD4+ cells and few CD8+ cells, while 77% of high-grade g BRCA2 patients were enriched in high levels of free, non-aggregated CD8+ T-cells in the tumor area. HLA-A expression was 2.37 times higher in g BRCA2 patients ( p = 3.4x10 −8 ), who also showed higher expression of genes associated with a present but suppressed immune system ( p = 1.4x10 −4 ). gBRCA2 patients with larger T-cell aggregates had an overall poorer prognosis compared to patients without (time to metastasis 55.1 vs. 85.3 months, survival time 67.3 vs. 85.0 months). Conclusions: g BRCA2 carriers displayed higher levels of HLA-A, more free CD8+ T cells infiltrating tumor regions and higher inflammatory signatures, suggesting an immune system that could potentially be harnessed. The degree of clustering of T cells (free vs. aggregated) within the TME may provide valuable prognostic information that warrants further validation.

    Abstract: Systemic Therapy for Advanced or Metastatic Prostate Cancer: Evaluation of Drug Efficacy is a randomized controlled trial using a multiarm, multistage, platform design. It recruits men with high-risk, locally advanced or metastatic prostate cancer who were initiating long-term hormone therapy. We report survival data for two celecoxib (Cel)-containing comparisons, which stopped accrual early at interim analysis on the basis of failure-free survival. Patients and Methods Standard of care (SOC) was hormone therapy continuously (metastatic) or for ≥ 2 years (nonmetastatic); prostate (± pelvic node) radiotherapy was encouraged for men without metastases. Cel 400 mg was administered twice a day for 1 year. Zoledronic acid (ZA) 4 mg was administered for six 3-weekly cycles, then 4-weekly for 2 years. Stratified random assignment allocated patients 2:1:1 to SOC (control), SOC + Cel, or SOC + ZA + Cel. The primary outcome measure was all-cause mortality. Results were analyzed with Cox proportional hazards and flexible parametric models adjusted for stratification factors. Results A total of 1,245 men were randomly assigned (Oct 2005 to April 2011). Groups were balanced: median age, 65 years; 61% metastatic, 14% N+/X M0, 25% N0M0; 94% newly diagnosed; median prostate-specific antigen, 66 ng/mL. Median follow-up was 69 months. Grade 3 to 5 adverse events were seen in 36% SOC-only, 33% SOC + Cel, and 32% SOC + ZA + Cel patients. There were 303 control arm deaths (83% prostate cancer), and median survival was 66 months. Compared with SOC, the adjusted hazard ratio was 0.98 (95% CI, 0.80 to 1.20; P = .847; median survival, 70 months) for SOC + Cel and 0.86 (95% CI, 0.70 to 1.05; P =.130; median survival, 76 months) for SOC + ZA + Cel. Preplanned subgroup analyses in men with metastatic disease showed a hazard ratio of 0.78 (95% CI, 0.62 to 0.98; P = .033) for SOC + ZA + Cel. Conclusion These data show no overall evidence of improved survival with Cel. Preplanned subgroup analyses provide hypotheses for future studies.

    Abstract: Patients with relapsed or refractory chronic lymphocytic leukemia (CLL) have profound immune defects and limited treatment options. Given the dramatic activity of lenalidomide in other B-cell malignancies and its pleotropic immunomodulatory effects, we conducted a phase II trial of this agent in CLL. Patients and Methods Patients with relapsed or refractory B-cell CLL (B-CLL) were eligible if they required treatment as per the National Cancer Institute Working Group 1996 guidelines. Lenalidomide was administered orally at 25 mg on days 1 through 21 of a 28-day cycle. Response was assessed after each cycle. Patients were to continue treatment until disease progression, unacceptable toxicity, or complete remission. Rituximab was added to lenalidomide on disease progression. Results Forty-five patients were enrolled, with a median age of 64 years. Sixty-four percent of the patients had Rai stage III or IV disease, and 51% were refractory to fludarabine. The overall response rate was 47%, with 9% of the patients attaining a complete remission. Fatigue, thrombocytopenia, and neutropenia were the most common adverse effects noted in 83%, 78%, and 78% of the patients, respectively. Conclusion Lenalidomide is clinically active in patients with relapsed or refractory B-CLL. These findings are encouraging and warrant further investigation of this agent in the treatment of this disorder.

    Abstract: 162 Background: STAMPEDE is a randomised controlled trial using a multi-arm multi-stage design. It recruits men (pts) with high-risk locally advanced or metastatic prostate cancer (PCa) starting long-term hormone therapy (HT) for the first time. The trial initially assessed adding one or two of three treatment approaches to standard-of-care (SOC). We report comparative survival data for the two original comparisons that stopped accrual early at pre-planned lack-of-activity analysis based on failure-free survival (FFS): celecoxib (Cox) and celecoxib + zoledronic acid (Cox+ZA). Methods: SOC was HT for at least 2yrs; RT was encouraged for men with M0 disease. Stratified randomisation allocated pts 2:1:1 to SOC (control), SOC+Cox or SOC+Cox+ZA. Celecoxib (400mg) was given twice daily until 1yr. Zoledronic acid (4mg) was given for six 3-weekly cycles then 4-weekly until 2yrs. The primary outcome measure was death from any cause. This pre-planned analysis is triggered by analysis of the “original comparisons” that continued accrual through all activity stages. Analyses use Cox proportional hazards model and flexible parametric models, all adjusted for stratification factors. Results: 1,245 men were contemporaneously randomised to these 3 arms (Oct2005-Apr2011). Groups were well balanced: median age 65yrs; 61% metastatic, 14% N+/X M0, 25% N0M0; 94% newly-diagnosed; median PSA 66ng/ml. Median follow-up was 62m. Grade 3-5 adverse events were seen in 35% SOC, 32% SOC+Cox, 32% SOC+Cox+ZA. There were 295 control arm deaths (82% PCa); median survival 68m. The adjusted HR was 1.00 (95% CI 0.82-1.22; p=0.99; median OS 69m) for SOC+Cox vs SOC; and 0.86 (95%CI 0.70-1.06; p=0.16; median OS 74m) for SOC+Cox+ZA vs SOC. Pre-planned analyses in men with metastatic disease showed HR 0.78 (95%CI 0.62-0.99) for SOC+Cox+ZA vs SOC. Further data will be shown. Conclusions: These data show no survival advantage for the addition of celecoxib alone for men starting long-term HT for the 1 st time. However, the addition of celecoxib combined with ZA demonstrated a survival advantage for men with metastatic disease, in a pre-planned analysis, and requires further investigation. Clinical trial information: NCT00268476.

    Abstract: 5503 Background: The combination of cisplatin and radiotherapy is a standard treatment for patients with locally advanced SCCHN. Cetuximab-radiotherapy is superior to radiotherapy alone in this population, validating EGFR as a target. Erlotinib, a small molecule inhibitor of EGFR, has activity in recurrent/metastatic disease. Adding EGFR inhibition to standard cisplatin-radiotherapy may improve efficacy. Methods: Patients with locally advanced SCCHN were randomized to receive cisplatin 100mg/m 2 on days 1,22 and 43 combined with 70Gy of radiotherapy (arm A) or the same chemoradiotherapy combined with erlotinib 150mg/day, starting one week prior to radiotherapy and continued to its completion (arm B). Randomizing 204 patients had 80% power to compare a 60% complete response rate (CRR) to a 40% null rate. Available tumors were tested for p16, ERCC1 and EGFR FISH. Results: Between June 2006 and October 2011, 204 patients were randomized. Results presented are based on intention to treat. There were more females on arm A however no other differences in patient characteristics, including p16 positivity. Patients on arm B had more rash and gastrointestinal adverse events, but treatment arms did not differ for rates of other grade III/IV toxicities or serious adverse events (SAEs). Arm A had a CRR of 61% and arm B had a CRR of 68% (p=0.3). With a median follow-up of 23 months, there were only 29 events in the overall survival analysis and 46 in the progression-free survival (PFS) analysis. The 2 and 3 year PFS were 71% and 63% for arm A and 78% and 73% for arm B (p=0.61). Conclusions: The addition of erlotinib did not increase the rate of SAEs but failed to significantly increase CRR. As seen in other recent trials, our results in both arms are superior to historical comparisons. Updated PFS data will be presented. Supported by a grant from the investigator-initiated trial program of Genentech/OSI.

    Abstract: e14592 Background: There are high rates of recurrence following definitive surgery in patients (pts) with biliary tract cancers (BTCs). Our aim was to review patterns of use and effectiveness of adjuvant therapy (AT) (chemotherapy (CT) +/- radiotherapy (RT)) in pts who underwent definitive surgery for BTC at a tertiary referral centre (Princess Margaret Hospital, Toronto). Methods: The clinical/pathological characteristics, treatment details and survival data of all pts with a diagnosis of BTC who had definitive surgery from Jan 1987 to Sept 2011 were reviewed. Results: The cohort includes 297 pts of which 42% were male, with a median age of 63 yrs, performance status 0-1 in 88%. 56 (19%) had well differentiated, 144 (48%) moderately and 60 (2%) poorly differentiated tumors, 37 (12%) data not available (NA). 125 (42%) and 41 (14%) had R0/R1 resection respectively, 131 (44%) NA. 122 (41%) were node positive, 72 (24%) NA. AT was given in 78 (27%) pts, 49 receiving adjuvant CT and 29 concurrent CT/RT; 34% receiving AT in distal bile duct, 14% in gallbladder, 12% in intrahepatic and 27% in klatskin. 179 (60%) pts recurred; 56/78 (72%) in the AT group (grp) and 123/179 (68%) in non-AT grp, 40 (13%) NA. In the AT and non-AT grps, local recurrence was seen in 7/56 (13%) and 26/123 (21%), distant in 32/56 (57%) and 73/123 (59%), and both in 176/56 (30%) and 24/123 (20%) respectively. In multivariate analysis, node positivity, HR 0.54, 95% CI 0.37 – 0.77, (p=0.001) was the only prognostic factor of DFS after definitive surgery. In node positive population (n=48 with AT, 50 without AT), median DFS was greater in AT grp; 13.8mo vs. 10.4mo (p=0.068). DFS and overall survival (OS) for entire cohort is detailed in Table. Conclusions: Given the limits of this retrospective cohort analysis and potential bias to treat higher risk pts, it does appear that pts receiving adjuvant therapy with node positive disease derived DFS advantage following definitive surgery, though not significant, and is probably an effective option for node positive, curative resected, BTC. However, larger prospective trials are paramount. [Table: see text]

    MASS-FIX versus standard methods to predict for PFS and OS among multiple myeloma patients participating on the STAMINA trial.
    American Society of Clinical Oncology (ASCO) ; 2021

    Abstract: 8009 Background: Measuring response among patients with multiple myeloma is essential for the care of patients. Deeper responses have been associated with better progression free survival (PFS) and overall survival (OS). Serum (SIFE) and urine immunofixation are the currently used markers for biochemical documentation of CR after which marrow is tested for plasma cell clearance. Next generation flow cytometry and sequencing are used to document the presence of minimal residual disease (MRD). Mass spectrometry of blood by MALDI (Mass-Fix) is a new simple, inexpensive, sensitive, and specific means of detecting monoclonal immunoglobulins. To better test the hypothesis that Mass-Fix is superior to existing methodologies to predict for survival outcomes—especially SIFE-- samples from the STAMINA trial (NCT01109004), a trial comparing 3 transplant approaches among patients who have already received induction, were employed. Methods: Five-hundred and seventy-five patients were included. Samples from enrollment post-induction (post-I) and 1-year post enrollment (1YR) were tested when available. Four response parameters were assessed univariately: Mass-Fix, SIFE, complete response, and MRD by next generation flow cytometry. Mass spectrometry spectra were evaluated in a blinded fashion. Complete response was according to the 2006 International Myeloma Working Group criteria. Multivariate Cox proportional hazard models using stepwise regression were developed to explore the independent effect of the different response parameters on PFS and OS and interactions with other risk factors. Results: Of the 4 response measures, only MRD and Mass-Fix predicted for PFS and OS at multiple testing points on multivariate analyses (Table). Of the 4 post-I measurements, only MRD predicted for PFS; however, Mass-Fix was the only post-I measurement to predict for OS. Of all the 1-year measures, both 1YR Mass-Fix and 1YR MRD positivity predicted for inferior PFS and OS. In models including MRD and Mass-Fix, SIFE and CR were not prognostic for PFS or OS. Conclusions: Mass-Fix is a powerful means to track monoclonal proteins. The full utility of Mass-Fix was not exploited given the absence of a diagnostic sample and the fact that only serum (and not urine) was tested. Despite these limitations, it performed well at pre-induction and at 1 year. Mass-Fix provides a convenient and non-invasive means of predicting for myeloma outcomes. Clinical trial information: NCT01109004. [Table: see text]

    Abstract: 323 Background: In CheckMate 9ER, patients (pts) with aRCC were randomized 1:1 to nivolumab 240 mg IV Q2W + cabozantinib 40 mg PO QD (N+C; n = 323) or sunitinib (S) 50 mg PO (4 weeks of 6-week cycles; n = 328). As reported previously, at a median follow-up of 18.1 months, N+C led to superior progression-free and overall survival and more favorable HRQoL than S. We report results of HRQoL analyses for 32.9-months follow-up. Methods: Disease-related symptoms (DRS) were evaluated using the FKSI-19 instrument and HRQoL with the EQ-5D-3L visual analogue scale (VAS). Change from baseline (BL) was assessed using mixed-model repeated measures (MMRM), adjusting for baseline scores and stratification factors, and included all common timepoints (at BL and every 6 wks) through week 151. Time to deterioration analysis was conducted for first (TFD), confirmed (TCD) and definitive (TDD) deterioration events using Kaplan-Meier estimates and Cox proportional hazards models. Bother with treatment side effects (item GP5 in FKSI-19) was assessed using a generalized estimating equations model with response dichotomized as minimal bother (not at all or a little bit) vs notable bother (somewhat, quite a bit, and very much). HRQoL endpoints were exploratory and P-values are nominal and descriptive. Results: Group mean scores over time show that HRQoL was maintained or improved from BL with N+C while reductions were observed with S. Overall changes from BL though week 151 favored N+C with nominal significant differences between treatments observed for all scores except functional well-being (FWB; Table). Similarly, decreased risk of deterioration was observed with N+C vs S for all scores except FWB, irrespective of the deterioration definition used (TFD, TCD, TDD). Pts in N+C arm were 48% (odds ratio: 0.52 [95% CI, 0.35-0.77]) less likely to be notably bothered by side effects than pts in S arm. Conclusions: Pts continued to report improved HRQoL with N+C compared to S. Treatment with N+C reduced the risk of meaningful deterioration in HRQoL scores, regardless of the definition of deterioration and showed a decreased risk of being bothered by treatment side effects in contrast to S. These results suggest that the superior efficacy of N+C over S with the additional benefit of improved HRQoL is maintained with longer follow-up. Clinical trial information: NCT03141177.

    Abstract: To test induction chemotherapy (IC) followed by concurrent chemoradiotherapy (CRT) or surgery/radiotherapy (RT) for advanced oropharyngeal cancer and to assess the effect of human papilloma virus (HPV) on response and outcome. Patients and Methods Sixty-six patients (51 male; 15 female) with stage III to IV squamous cell carcinoma of the oropharynx (SCCOP) were treated with one cycle of cisplatin (100 mg/m 2 ) or carboplatin (AUC 6) and with fluorouracil (1,000 mg/m 2 /d for 5 days) to select candidates for CRT. Those achieving a greater than 50% response at the primary tumor received CRT (70 Gy; 35 fractions with concurrent cisplatin 100 mg/m 2 or carboplatin (AUC 6) every 21 days for three cycles). Adjuvant paclitaxel was given to patients who were complete histologic responders. Patients with a response of 50% or less underwent definitive surgery and postoperative radiation. Pretreatment biopsies from 42 patients were tested for high-risk HPV. Results Fifty-four of 66 patients (81%) had a greater than 50% response after IC. Of these, 53 (98%) received CRT, and 49 (92%) obtained complete histologic response with a 73.4% (47 of 64) rate of organ preservation. The 4-year overall survival (OS) was 70.4%, and the disease-specific survival (DSS) was 75.8% (median follow-up, 64.1 months). HPV16, found in 27 of 42 (64.3%) biopsies, was associated with younger age (median, 55 v 63 years; P = .016), sex (22 of 30 males [73.3%] and five of 12 females [41.7%] ; P = .08), and nonsmoking status (P = .037). HPV titer was significantly associated with IC response (P = .001), CRT response (P = .005), OS (P = .007), and DSS (P = .008). Conclusion Although the numbers in this study are small, IC followed by CRT is an effective treatment for SCCOP, especially in patients with HPV-positive tumors; however, for patients who do not respond to treatment, alternative treatments must be developed.
