Abstract Background The phase 3 JAVELIN Bladder 100 trial showed significantly prolonged overall survival (OS) with avelumab as first-line (1L) maintenance therapy + best supportive care (BSC) vs BSC alone in patients with advanced urothelial carcinoma (UC) that had not progressed with 1L platinum-containing chemotherapy. Efficacy and safety were assessed in patients enrolled in Japan. Methods Patients with locally advanced or metastatic UC that had not progressed with 4–6 cycles of 1L platinum-containing chemotherapy were randomized to avelumab (10 mg/kg intravenously every 2 weeks) + BSC or BSC alone. The primary endpoint was OS, and secondary endpoints included progression-free survival (PFS) and safety. Results In Japanese patients (n = 73) randomized to avelumab + BSC (n = 36) or BSC alone (n = 37), median OS was 24.7 months (95% CI, 18.2-not estimable) vs 18.7 months (95% CI, 12.8–33.0), respectively (HR, 0.81 [95% CI, 0.41–1.58]), and median PFS was 5.6 months (95% CI, 1.9–9.4) vs 1.9 months (95% CI, 1.9–3.8), respectively (HR, 0.63 [95% CI, 0.36–1.11]). In the avelumab + BSC and BSC-alone arms, grade ≥ 3 treatment-emergent adverse events (AEs) occurred in 50.0% vs 8.1%, including grade ≥ 3 treatment-related AEs in 13.9% vs 0%, respectively. Efficacy and safety results in Japanese patients were generally consistent with findings in the overall trial population. Conclusion Avelumab 1L maintenance treatment showed a favorable benefit-risk balance in Japanese patients, supporting avelumab 1L maintenance as a new standard of care in Japanese patients with advanced UC that has not progressed with 1L platinum-containing chemotherapy. Trial registration Clinicaltrials.gov NCT02603432.

425 Background: A randomized phase III trial (JAVELIN Bladder 100; NCT02603432) to investigate avelumab (anti–PD-L1) as 1L maintenance therapy in patients with advanced UC met its primary objective, demonstrating significantly prolonged overall survival (OS) with Ave + BSC vs BSC alone in all randomized patients and in patients with PD-L1+ tumors. We report efficacy and safety in Japanese patients enrolled in this study. Methods: Eligible patients with unresectable locally advanced or metastatic UC that had not progressed with 4-6 cycles of gemcitabine with either cisplatin or carboplatin were randomized 1:1 to receive maintenance Ave (10 mg/kg IV every 2 weeks) + BSC or BSC alone, stratified by best response to 1L chemotherapy (complete/partial response vs stable disease) and by visceral vs nonvisceral disease when initiating 1L chemotherapy. The primary endpoint was OS, assessed from randomization in all randomized patients and in patients with PD-L1+ tumors (Ventana SP263 assay). Secondary endpoints included progression-free survival (PFS) per blinded independent central review and safety. Results: Japanese patients (n=73) were randomized to receive Ave + BSC (n=36) or BSC alone (n=37); 52.8% vs 62.2% had PD-L1+ tumors, respectively. Median OS (95% CI) was 24.7 months (18.2-not estimable [NE]) with Ave + BSC vs 18.7 months (12.8-33.0) with BSC alone (HR, 0.81 [95% CI; 0.409-1.585]) in all randomized patients and 18.6 months (9.4-NE) with Ave + BSC vs 19.4 months (11.7-33.0) with BSC alone (HR, 1.00 [95% CI, 0.413-2.412]) in patients with PD-L1+ tumors. Median PFS (95% CI) was 5.6 months (1.9-9.4) with Ave + BSC vs 1.9 months (1.9-3.8) with BSC alone (HR, 0.63 [95% CI, 0.358-1.113]) in all randomized patients and 5.6 months (1.8-11.2) with Ave + BSC vs 1.9 months (1.9-3.8) with BSC alone (HR, 0.62 [95% CI, 0.298-1.301]) in patients with PD-L1+ tumors. The most common treatment-emergent adverse events (all grade; grade ≥3) in the Ave + BSC arm were pyrexia (10 [27.8%]; 0), nasopharyngitis (7 [19.4%]; 0), and anemia (7 [19.4%]; 4 [11.1%]). Conclusions: Ave 1L maintenance + BSC was efficacious and tolerable in Japanese patients with advanced UC, and results were generally consistent with those in the overall population.

404 Background: To evaluate the clinical impact of gemcitabine (GEM) monotherapy after 1st line GEM with platinum in patients with metastatic urothelial carcinoma. Methods: We retrospectively reviewed the medical records of 113 patients who showed with radiological response or stabilization after 4-6 cycles of GEM with platinum.61 patients received maintenance of GEM-mono (GEM group) as 1000 mg/m2 on day 1 and 8 every three weeks until progression or development of unacceptable toxicity. And 52 patients received best supportive care (BSC) with regular radiologic evaluation (BSC group). Progression free survival (PFS) and overall survival (OS) from start date of GEM-mono or BSC was examined. Results: After a median follow-up of all population of 8.21 months, 43 (70%) patients had progressed and 32 (52%) died in the GEM-mono arm, compared to 45 (86%) and 39 (76%) in the BSC arm, respectively. Maintenance of GEM-mono was for a median 6 cycles (2-19). Median PFS was 7–12 months (range 1.5-13.0) in the GEM-mono arm and 4–8 months (range 1.4-8.6) in the BSC arm (Hazard Ratio 0.580, 95%CI 0.38-0.95, p=0.032). Most common grade 3/4 adverse events in the GEM arm were neutropenia (n=11; 18%) and fatigue (n=13; 21%). After progression, 42 (68%) patients received treatment at the GEM and 30 (58%) at the BSC arm. Conclusions: Our data suggest that maintenance of GEM-mono therapy in patients who responded to 1st line GEM with platinum provides a significant prolongation of PFS, and with a manageable toxicity profile.

LBA1 Background: Platinum-based chemotherapy is an active 1L regimen for advanced UC; however, progression-free survival (PFS) and overall survival (OS) are generally short because of chemotherapy resistance. This randomized, phase 3 trial (JAVELIN Bladder 100; NCT02603432) evaluated avelumab (anti–PD-L1) as maintenance therapy following response or stable disease with 1L platinum-based chemotherapy in patients with advanced UC. Methods: Eligible patients with unresectable locally advanced or metastatic UC without disease progression after 4-6 cycles of gemcitabine with either cisplatin or carboplatin were randomized 1:1 to receive maintenance avelumab (10 mg/kg IV every 2 weeks) + best supportive care (BSC) or BSC alone, stratified by best response to 1L chemotherapy (complete/partial response vs stable disease) and by visceral vs nonvisceral disease when initiating 1L chemotherapy. The primary endpoint was OS, assessed from randomization in 2 primary populations: all randomized patients and patients with PD-L1+ tumors (Ventana SP263 assay). Secondary endpoints included PFS, objective response, and safety. Results: 700 patients were randomly assigned to maintenance avelumab + BSC (n=350) or BSC alone (n=350) and were followed for a median of 19.6 and 19.2 months, respectively. Overall, 358 (51%) had PD-L1+ tumors. Avelumab + BSC significantly prolonged OS vs BSC alone in all randomized patients (hazard ratio [HR] 0.69; 95% CI 0.56, 0.86; 1-sided p=0.0005); median OS with avelumab + BSC vs BSC alone was 21.4 vs 14.3 months, respectively. Avelumab + BSC also significantly prolonged OS vs BSC alone in patients with PD-L1+ tumors (HR 0.56; 95% CI 0.40, 0.79; 1-sided p=0.0003); median OS was not reached vs 17.1 months, respectively. An OS benefit was also observed across all prespecified subgroups. The HR for PFS based on blinded independent central review with avelumab + BSC vs BSC alone was 0.62 (95% CI 0.52, 0.75) in all randomized patients and 0.56 (95% CI 0.43, 0.73) in patients with PD-L1+ tumors. In treated patients in the avelumab + BSC (n=344) vs BSC alone (n=345) arms, respectively, all-causality adverse events (AEs) were reported at any grade in 98.0% vs 77.7% and at grade ≥3 in 47.4% vs 25.2%, and the most frequent grade ≥3 AEs were urinary tract infection (4.4% vs 2.6%), anemia (3.8% vs 2.9%), hematuria (1.7% vs 1.4%), fatigue (1.7% vs 0.6%), and back pain (1.2% vs 2.3%). Conclusions: JAVELIN Bladder 100 met its primary objective, demonstrating significantly prolonged OS with 1L maintenance avelumab + BSC vs BSC alone in advanced UC in all randomized patients and patients with PD-L1+ tumors. Efficacy benefits were seen across all prespecified subgroups, and the safety profile of avelumab was consistent with previous studies of monotherapy. Clinical trial information: NCT02603432 .

PurposeTo evaluate trastuzumab (H) and docetaxel (T) with or without capecitabine (X) as first-line combination therapy for human epidermal growth factor receptor 2 (HER2) -positive advanced breast cancer.Patients and MethodsPatients with HER2-positive locally advanced or metastatic breast cancer were randomly assigned to H (8 mg/kg loading; 6 mg/kg every 3 weeks) plus T (75 mg/m2in HTX arm, 100 mg/m2in HT arm, every 3 weeks) with or without X (950 mg/m2twice per day on days 1 to 14 every 3 weeks). The primary end point was overall response rate (ORR).ResultsIn 222 patients, median follow-up was approximately 24 months. ORR was high with both regimens (70.5% with HTX; 72.7% with HT; P = .717); complete response rate was 23.2% with HTX compared with 16.4% with HT. HTX demonstrated significantly longer progression-free survival: median 17.9 months compared with 12.8 months with HT (hazard ratio, 0.72; P = .045), which translates to a gain of around 5 months. Two-year survival probability was 75% with HTX compared with 66% with HT. Febrile neutropenia (27% v 15%) and grade 3/4 neutropenia (77% v 54%) incidences were higher with HT than HTX. Treatment-related grade 3 hand-foot syndrome (17% v < 1%) and grade 3/4 diarrhea (11% v 4%) occurred more commonly with HTX than HT. One case of congestive heart failure occurred in each arm.ConclusionHTX is an effective and feasible first-line therapy for HER2-positive locally advanced or metastatic breast cancer, although it should be reserved for patients with good performance status who are not receiving long-term steroids.

LBA2 Background: Gemcitabine-cisplatin (GP) chemotherapy is the standard 1st line treatment for locally advanced, recurrent or metastatic (r/m) NPC. Toripalimab, a humanized IgG4K monoclonal antibody specific for PD-1, provided durable responses in patients (pts) with r/m NPC as monotherapy in the ≥2nd line setting (POLARIS-02 study). The results of JUPITER-02, a randomized, placebo-controlled, double-blinded Phase III trial of toripalimab in combination with GP chemotherapy as first-line treatment for r/m NPC are summarized. Methods: Pts with advanced NPC with no prior chemotherapy in the r/m setting were randomized (1:1) to receive toripalimab 240 mg or placebo d1 in combination with gemcitabine 1000 mg/m2 d1, d8 and cisplatin 80 mg/m2 d1 every 3 weeks (Q3W) for up to 6 cycles, followed by monotherapy with toripalimab or placebo Q3W until disease progression, intolerable toxicity, or completion of 2 years of treatment. Stratification factors were ECOG PS (0 vs. 1) and extent of disease (recurrent vs. primary metastatic) at enrollment. Progression-free survival (PFS) and response were assessed by independent review committee (IRC) per RECIST v1.1. The primary endpoint was PFS by IRC in the ITT population. Secondary end points included ORR, DOR and OS. There was one prespecified interim analysis of PFS at 130 PFS events with a planned final analysis at 200 PFS events. Results: 289 pts were randomized: 146 to the toripalimab arm and 143 to the placebo arm. By May 30, 2020 as the interim analysis cutoff date, the median treatment duration was 39 weeks in the toripalimab arm and 36 weeks in the placebo arm. A significant improvement in PFS was detected for the toripalimab arm compared to the placebo arm (HR = 0.52 [95% CI: 0.36-0.74] two-sided p = 0.0003), with median PFS of 11.7 vs. 8.0 months. The 1-year PFS rates were 49% and 28% respectively. An improvement in PFS was observed across relevant subgroups, including all PD-L1 subgroups. The ORR was 77.4% vs. 66.4% (P = 0.033) and the median DOR was 10.0 vs. 5.7 months (HR = 0.50 [95% CI: 0.33-0.78]). As of Jan 15, 2021, OS was not mature, with 25 deaths in the toripalimab arm and 35 in the placebo arm (HR = 0.68 [95% CI: 0.41-1.14], P = 0.14). The incidence of Grade ≥3 adverse events (AEs) (89.0% vs 89.5%); AEs leading to discontinuation of toripalimab/placebo (7.5% vs 4.9%); and fatal AEs (2.7% vs 2.8%) were similar between two arms; however, immune-related (irAEs) (39.7% vs. 18.9%) and Grade ≥3 irAEs (7.5% vs. 0.7%) were more frequent in the toripalimab arm. Conclusions: The addition of toripalimab to GP chemotherapy as 1st-line treatment for pts with advanced NPC provided superior PFS and ORR and longer DOR than GP alone with a manageable safety profile. These results support the use of toripalimab with GP chemotherapy as the new standard care for this population. Clinical trial information: NCT03581786.

Background Combined androgen blockade (cab) is a promising treatment modality for prostate cancer (pca). In the present meta-analysis, we compared the efficacy and safety of first-line cab using an antiandrogen (aa) with castration monotherapy in patients with advanced pca.Methods PubMed, embase, Cochrane, and Google Scholar were searched for randomized controlled trials (rcts) published through 12 December 2016. Hazard ratios (hrs) with 95% confidence intervals (cis) were determined for primary outcomes: overall survival (os) and progression-free survival (pfs). Subgroup analyses were performed for Western compared with Eastern patients and use of a nonsteroidal aa (nsaa) compared with a steroidal aa (saa).Results Compared with castration monotherapy, cab using an aa was associated with significantly improved os (n = 14; hr: 0.90; 95% ci: 0.84 to 0.97; p = 0.003) and pfs (n = 13; hr: 0.89; 95% ci: 0.80 to 1.00; p = 0.04). No significant difference in os (p = 0.71) and pfs (p = 0.49) was observed between the Western and Eastern patients. Compared with castration monotherapy, cab using a nsaa was associated with significantly improved os (hr: 0.88; 95% ci: 0.82 to 0.95; p = 0.0009) and pfs (hr: 0.85; 95% ci: 0.73 to 0.98; p = 0.007)—a result that was not achieved with cab using a saa. The safety profiles of cab and monotherapy were similar in terms of adverse events, including hot flushes, impotence, and grade 3 or 4 events, with the exception of risk of diarrhea and liver dysfunction or elevation in liver enzymes, which were statistically greater with cab using an aa.Conclusions Compared with castration monotherapy, first-line cab therapy with an aa, especially a nsaa, resulted in significantly improved os and pfs, and had an acceptable safety profile in patients with advanced pca.
