e602 Background: The clinical experience with CBZ in mCRPC patients (pts) has enriched notably since its approval for clinical use, but there is still a lack of well-defined prognostic/predictive factors to better characterize the profile of pts that could achieve the best therapeutic benefit. Analysis of the final expanded cohort and mature long-term follow-up are presented. Methods: Medical records from mCRPC pts progressing during or after docetaxel and treated with CBZ at 21 centres in Spain were reviewed retrospectively. Baseline characteristics, overall survival (OS), radiographic progression-free survival (rPFS), and toxicity were collected. Univariate and multivariate analysis of a variety of factors predicting OS were conducted. Results: 187 consecutive pts (median age 69) with intermediate-poor prognostic baseline characteristics (Table 1) received a median of 6 cycles (range 2-59) of CBZ. Median OS from first CBZ cycle was 15.3 [CI: 11.7; 18.0] months (mo) and median clinical and/or rPFS was 7.9 mo [CI: 6.8; 10.3]. Gleason score (GS) < 8 (vs ≥ 8), time under first-line androgen deprivation therapy (ADT) ( > 16.1 (median) vs < 16.1 mo) and the number of chemotherapy lines before CBZ did not significantly influence OS. Median follow-up was 9.5 mo. Febrile neutropenia occurred in 4 pts and 1 pt had neutropenic infection. Main nonhematologic grade ≥ 3 toxicities were asthenia (2.7%) and diarrhea (1.6%). Alopecia, nails disorders and peripheral neuropathy were uncommon. Conclusions: CBZ administered in the daily clinical practice is associated with consistent OS, similar to that observed in pivotal clinical trials. GS, median time under first-line ADT and number of chemotherapy lines before CBZ did not influence clinical benefit. CBZ has an acceptable safety profile. Funding: Sanofi [Table: see text]

246 Background: STRIDE (NCT01981122) is the first study comparing concurrent (con) vs sequential (seq) enzalutamide (enz) with sipuleucel-T (sip-T) in patients (pts) with metastatic castration-resistant prostate cancer. Pts were followed until death or for 3 years. Methods: Fifty-two pts were randomized 1:1 to 3 sip-T infusions and enz started 2 wks before (n = 25, con) or 10 wks after (n = 27, seq) sip-T. Enz was continued for 52 wks or until disease progression (DP)/toxicity. Time to clinical outcomes was estimated by Kaplan-Meier analysis. Results: Median age (years): con 66; seq 72 (p = 0.01). Baseline characteristics and laboratory values were similar between arms. K-M estimated median follow up: 40.2 months. Clinical trial information: NCT01981122. Conclusions: Long-term follow-up suggests sip-T+enz is well-tolerated with no new safety concerns. Though not powered for such, con vs seq rx did not result in differences in OS or DP; differences in PSA responses cannot be excluded. Larger studies could better evaluate the clinical impact of combining immunotherapy with hormonal agents.[Table: see text]

Abstract Objective: To evaluate the efficacy and long-term outcome of the total treatment of induction therapy, ASCT and consolidation and maintenance therapy. Methods: A retrospective analysis was made on in multiple myeloma patients in our center between April 1, 2003 and February 1, 2016. The 157 patietns received autologous hematopoietic stem cell transplantation and review the autologous transplantation of long-term follow-up results. Analysis of the effect of transplantation efficacy, the impact on survival remission of different transplantation depth, transplantation in first line or not, salvage transplantation, prognosis of different staging system and other factors. Results: The baseline characteristics of the patients were shown in table 1. Overall patient ASCT before total effective rate (ORR) was 93.6%, in which the complete remission (CR) ratio was 33.1%. After ASCT, the best treatment response rate of PR was 80.3%, and the rate of CR was 58.6%. 91.69 months of median follow-up, patients with an overall survival (OS) and progression free survival (PFS) respectively 91.69 and 50.76 months; in 2005 before the median OS and PFS 39.0m and 23.0m. In 2005 after respectively and 56.41m 120.90m, P = 0.000. The median OS and PFS in the first line transplantation group and salvage transplantation group were vs 54.21m 39.0m and vs 7.09m 119.0m (P value was 0). 136 cases of patients with R-ISS stage, I, II, III of the patients with the median survival time were 120.90m (n=46), 86.43m (n=69), 35.65m (n=21), there were significant differences between groups, p=0.000. Each period of PFS were 72.11m, 51.84m, 28.09m, I and II, III,, p=0.001 and p=0.03, while there was no significant difference between II and III, p=0.122. The received autologous transplantation as first-line and salvage treatment of patients with subgroup survival analysis, median OS of the R-ISS stage III patients and different 15.84m 35.65m, P = 0.031; two groups of patients the median PFS (phase I: 91.69m vs18.92m; II: vs 16.69m 53.42m; phase III: vs 5.91m 28.52m) have difference (P = 0.000). In the first-line transplantation group, transplantation is more than or equal to PR and did not get effective PR group between OS were significantly different; before transplantation achieved CR, PR but did not obtain Cr and did not get effective PR group between PFS were significantly different; after transplantation and achieved CR CR did not get the patients had a median PFS were 65.57m 48.13m, P = 0.039 and median OS no difference. Accept any kind of noval agent- based chemotherapy were significantly longer OS and PFS than traditional chemotherapy (P = 0.001, P = 0.004) .There was no obvious difference on median OS between based regimen (bortezomib group median OS: NR; thalidomide group:120.90m); PFS in thalidomide group (median PFS : NR vs 54.21m) significantly prolonged (P = 0.010). By comparing the baseline characteristics of the two groups, it was found that the PFS was significantly shorter in the bortezomib group with an extra medullary lesion. Multivariate analysis showed that only R-ISS and the depth of remission before transplantation had effect on OS (p=0.003) and PFS (p=0.036) respectively. Conclusion: The total treatment of novel agent-based chemotherapy and ASCT for transplantation-eligible multiple myeloma patients is effective, further improve the remission rate and remission depth, prolong PFS and OS, the overall median survival up to 120.9m. First line transplantation can significantly prolong the OS and PFS compared with salvage transplantation. R-ISS and pre-transplant remission depth are prognostic factors influencing survival of patients. The total treatment to thalidomide based without extramedullary perhaps makes patients get long-term survival. Disclosures No relevant conflicts of interest to declare.

8050 Background: Concurrent chemoradiotherapy has been regarded as one of the standard management for localized nasal NKTCL. However, its long-term efficacy and toxicity is not known. Methods: The JCOG0211 trial is a phase I/II study of concurrent chemoradiotherapy consisting of radiotherapy (RT) of 50 Gy and 3 cycles of DeVIC (carboplatin, etoposide, ifosfamide, dexamethasone) for newly diagnosed, localized nasal NKTCL (JCO 2009). Patients (Pts) with newly diagnosed, localized diseases (IE & contiguous IIE with cervical node involvement) who were 20-69 yrs of age with PS 0-2 were eligible. 3-D conformal RT planning with a wide margin (+ 2 cm to the gross tumor, the entire nasal cavity and the nasopharynx) and a 2-step cone down were required. 33 pts were enrolled in the study, 27 of whom were treated with RT and a 2/3-dose of DeVIC, which was selected as the recommended phase II dose in the preceding phase I portion of the trial. All pts completed RT without any protocol violations. Long-term follow-up results on overall survival (OS), progression-free survival (PFS) and toxicity were evaluated. Results: The median follow-up was 69 months (range, 62-96). The pt (N=33) characteristics were as follows: median age 54 yrs (range, 21-68); stage IIE 33%; B symptom (+) 36%; elevated serum LDH 21%. %5-yr OS and PFS were 73% (95%CI, 54-85%) and 67% (95%CI, 48-80%), respectively. 11 pts (33%) experienced disease recurrence. Two achieved a 2nd CR by salvage chemotherapies followed by allogeneic stem cell transplantation, and the remaining 9 pts died of disease. There was no observed death and disease progression after 34 and 31 months, respectively. One pt experienced Grade 3 irregular menstruation for 3 years. No other Grade 3 or 4 late non-RT-associated adverse events (AEs) were observed. One pt received plastic surgery due to Grade 4 RT dermatitis. No other Grade 3 or greater RT-associated late AEs were encountered. Conclusions: Both survival benefit and disease control from concurrent chemoradiotherapy with RT and DeVIC are maintained during a 5-yr follow-up, indicating the excellent efficacy of this approach as a first-line therapy for localized nasal NKTCL. Long-term toxicity is acceptable.

7528 Background: Previously in the COMPLEMENT 1 study, treatment with OFA and CHL in pts with untreated CLL had shown a significant improvement in the progression-free survival (PFS) compared with CHL alone, and was well tolerated. Here, we report the final overall survival (OS) analysis of the 5-year (y) follow-up, updated investigator-assessed PFS and safety from the study. Methods: Untreated pts, not fit for fludarabine-based therapy (due to advanced age or co-morbidities) were randomized 1:1 to OFA+CHL or CHL alone. Pts in OFA+CHL arm received OFA (Cycle 1: 300 mg day (d) 1, 1000 mg d8; subsequent cycles: 1000 mg d1) in addition to CHL (10 mg/m2, d1-7) for 3 to 12 cycles of 28 d each. Pts in CHL arm received CHL only. Results: Overall, 447 pts were randomized to OFA+CHL (n = 221) or CHL (n = 226); 168 (76%) and 164 (73%) pts completed the scheduled treatments, respectively. Baseline characteristics were similar in both arms. The investigator-assessed median PFS was 23.4 months (mos) in the OFA+CHL arm and 14.7 mos in the CHL arm (HR: 0.61 [95% CI 0.49, 0.76], p < 0.001). Median OS could not be estimated for the OFA+CHL arm and was 84.7 mos for the CHL arm (HR: 0.88 [95% CI 0.65, 1.17], p = 0.363). Estimated OS rate (95% CI) at 5 y was 68.5% (61.5%, 74.5%) in the OFA+CHL arm, and 65.7% (58.6%, 71.9%) in the CHL arm. Post-treatment anti-cancer therapy after discontinuation was received by a greater proportion of pts in the CHL (66%) vs. OFA+CHL (56%), and started earlier in the CHL arm (486 d) vs. OFA+CHL (743 d) arm. Overall, 84 (39%) pts in the OFA+CHL, and 99 (44%) pts in the CHL arms died during the study with 5 on-treatment deaths in each group. Grade ≥3 adverse events were seen in 64% and 48% of pts in the OFA+CHL vs. CHL arms, respectively, most common being (≥5% in either arm) neutropenia (26% vs. 15%), thrombocytopenia (5% vs. 10%), pneumonia (9% vs. 5%), and anemia (5% vs. 5%). Conclusions: This 5-y survival follow-up analysis supported the results from primary analysis with an estimated 12% (not significant) and 39% risk reduction in OS and PFS, respectively, in the OFA+CHL arm compared with the CHL arm. No new safety concerns were observed in the OFA+CHL arm. Clinical trial information: NCT00748189.

190 Background: The optimal sequence and combination of life-extending anticancer therapies in mCRPC pts remains unknown. Sipuleucel-T (sip-T), an autologous cellular immunotherapy approved for the therapy of asymptomatic or minimally symptomatic metastatic castration-resistant prostate cancer (mCRPC) pts, was evaluated in combination with abiraterone acetate and prednisone (abi) in the phase II STAMP trial (NCT01487863), with pts randomly assigned to receive CON sip-T + abi or SEQ sip-T followed by abi. The combination was well-tolerated and did not alter the immune response parameters that correlate with overall survival (OS) (Small Clin Can Res 2015). Here, we present long-term follow-up of clinical outcomes, including OS. Methods: mCRPC pts were randomized 1:1 to CON or SEQ therapy with sip-T and abi. Abi began 1 day after (CON) or at wk 10 (SEQ) after the first sip-T infusion and continued for 26 wk of therapy, after which continued abi therapy was permitted. Long-term clinical outcomes included OS, disease-specific death (DSS), progressive disease (PD), time to first anticancer intervention (tACI), and safety. Results: 69 pts were enrolled (35 CON; 34 SEQ). Median OS was 34.0 mo (95% CI, 24.4-not estimable [NE]; 30.0 mo CON; 34.2 mo SEQ; p = 0.921), and median time to DSS was not reached (CON vs SEQ; p = 0.733). Median time to PD was 17.3 mo (95% CI, 9.7–NE; 17.7 mo CON vs 13.9 mo SEQ; p = 0.914; consistent with higher rates of abi discontinuation due to PD in SEQ [26.5% vs 14.3% in CON]). tACI was similar between arms at 15.4 mo (95% CI, 11.0–19.9). No new safety signals were observed with the combination, and no discernable difference in clinical outcomes was observed with CON or SEQ treatments. Conclusions: Long-term follow-up data confirm that sip-T + CON or SEQ abi is well-tolerated, with no new safety signals. No clear differences were observed in clinical outcomes between arms, although the study was not powered to detect these differences. Future and more appropriately powered studies on the effect of sip-T + continuous abi for responding pts may provide further insights on the benefit of combination therapy. Clinical trial information: NCT01487863.

97 Background: Cabazitaxel rechallenge could be a more efficient therapy with an acceptable toxicity than docetaxel in the treatment of patients with a metastatic castration resistant prostate cancer (mCRPC). The aim of this study was to assess the feasibility and efficacy of cabazitaxel multiple rechallenge. Methods: This is a multicenter, retrospective cohort study including patients from 9 centers in France who received 3 lines or more of cabazitaxel from February 2012 to July 2020. Cabazitaxel schedule differed between patients: 25 mg/m2 q3w, 20 mg/m2 q3w, 16 mg/m2 q2w or 10 mg/m2 weekly. Efficacy was assessed by overall survival (OS) and progression-free survival (PFS) from each cabazitaxel line start. Only toxicities grade ≥ 3 were reported. Results: Twenty-two patients were included. The median follow-up from mCRPC was 94.7 months, median age at initial diagnosis was 59.5 years old, median ISUP score at diagnosis was 4 and median PSA at diagnosis was 55 ng/ml. Median number of cabazitaxel cycles was 7 at first-line, 6 at first rechallenge, and 5 for subsequent rechallenges. Median OS from mCRPC diagnosis was 105 months. Median PFS from cabazitaxel line start was 11.8 months at first use, 9.6 for first rechallenge and 5.6 in second rechallenge (table). Only one case of febrile neutropenia and 6 events of grade ≥ 3 toxicity were reported. Conclusions: Cabazitaxel multiple rechallenge could efficiently extend OS with manageable toxicities for patients. Even if anti-PARP therapy and immunotherapy are promising treatments, cabazitaxel rechallenge could be also a relevant therapeutic option for long responder patients. Specific biomarkers should be explored to predict the efficacy of cabazitaxel rechallenge. [Table: see text]

e19507 Background: Tislelizumab is a humanized IgG4 monoclonal antibody with high affinity/specificity for programmed cell death protein 1 (PD-1). It was engineered to minimize binding to Fc-γ receptors on macrophages, thereby decreasing antibody-dependent phagocytosis, a potential mechanism of T-cell clearance and resistance to anti–PD-1 therapy. Tislelizumab therapy was highly active in autologous stem cell transplant (ASCT)-failed or ineligible patients with R/R cHL ( Leukemia. 2020;34:533). Here we report results from up to 3 years follow-up. Methods: This asingle-arm, multicenter phase 2 study (NCT03209973) of 200 mg tislelizumab administered intravenously to patients (pts) with R/R cHL every 3 weeks until progressive disease (PD) or unacceptable toxicity. Patients were eligible if they: failed to achieve a response or progressed after ASCT, or: received ≥2 lines of prior systemic chemotherapy for cHL and were ineligible for ASCT. Primary endpoint was overall response rate (ORR) assessed by an independent review committee (IRC) per Lugano criteria ( J Clin Oncol. 2014;32:3059). Secondary endpoints were progression-free survival (PFS), duration of response (DOR), complete response (CR) rate, and time to response (TTR) per IRC, safety, and tolerability. Results: Pts (N=70) from 11 centers in China were enrolled and treated; characteristics have been previously reported. As of the data cutoff date (Nov 2, 2020), median follow-up was 33.8 months (range, 3.4-38.6). Pts still on treatment at the end of study (n=33; 47.1%) entered a long-term extension study. Efficacy data is presented in the Table below. In the 13 pts who received prior ASCT, 11 (84.6%) achieved CR. The most common treatment-emergent adverse events (AEs; ≥30%) were pyrexia (57.1%), upper respiratory tract infection (38.6%), hypothyroidism (37.1%), and increased weight (34.3%). Treatment-related grade ≥3 AEs (≥2 pts) were pneumonitis, hypertension, neutropenia, lipase increased, weight increased, and increased creatine phosphokinase (CPK; 2.9% each). Immune-related AEs were reported in 32 pts (45.7%), with grade ≥3 AEs in 8 pts (11.4%): pneumonitis (4) and skin adverse reactions, nephritis, lipase increased, and blood CPK increased (1 each). AEs led to treatment discontinuation in 6 pts (8.6%). Conclusions: Long-term follow-up of R/R cHL pts treated with tislelizumab further demonstrated the substantial therapeutic activity and continued PFS benefit. There were no new safety concerns identified for long-term treatment with tislelizumab. Clinical trial information: NCT03209973. [Table: see text]

13578 Background: Capecitabine is an oral fluoropyrimidine with superior activity and safety compared with bolus 5-FU/LV in metastatic colorectal cancer (CRC). The aim of this study was to evaluate the efficacy and safety of a combination of capecitabine and oxaliplatin as first-line chemotherapy in patients with advanced CRC. Methods: Fourty-six patients (26 men and 20 women) with metastatic CRC entered this study. All patients were treated with capecitabine (1,000mg/m2 p.o.twice daily, days 1–14) and oxaliplatin (130mg/m2 on day 1). Cycles were repeated every 21 days until disease progression or unacceptable toxicity. Baseline characteristics: Median age 61 years (range 32–74), main sites of metastasis: Liver 32 patients (70%), liver and lungs 4 patients (9%), lungs 3 patients (6%), other sites 7 patients (15%). Results: 2 patients (4%) achieved complete response (CR), 17 patients (37%) achieved partial response (PR) and 7 patients (15%) attained stable disease (SD). With a median follow-up of 22 months the progression free survival was 7.5 months and overall survival was 19.0 months. All patients were assessable for toxicities. The most commonly encountered adverse events were from the gastrointestinal system (all grades 48%, grade 3, 6%). Neither toxic death nor life-threatening febrile neutropenia were reported. Conclusions: The combination of capecitabine and oxaliplatin is a convenient regimen in patients with advanced CRC that is associated with considerable efficacy and limited toxicity. No significant financial relationships to disclose.
