Polatuzumab vedotin plus bendamustine and rituximab (pola+BR) received regulatory approvals in relapsed/refractory diffuse large B-cell lymphoma (R/R DLBCL) based on primary results from the randomized arms of the GO29365 study. Following the randomized phase, 106 additional patients received pola+BR in a single-arm extension cohort. We report updated results from the randomized arms, and results of the extension cohort. In this phase Ib/II study, patients with R/R DLBCL who were transplant-ineligible received up to six 21-day cycles of pola+BR or BR. The primary endpoint of the randomized arms was complete response (CR) rate at end of treatment. Primary objectives of the extension cohort were safety, pharmacokinetics, and efficacy of pola+BR. As of July 7, 2020, 192 patients with R/R DLBCL were enrolled into pola+BR cohorts (n=152 [safety run-in: n=6; randomized: n=40; extension cohort: n=106]) or the BR cohort (n=40). Significant survival benefit with pola+BR versus BR persisted in the randomized arms (median progression-free survival [PFS]: 9.2 vs 3.7 months, hazard ratio [HR]: 0.42, 95% confidence interval [CI] 0.25-0.71 months; median overall survival [OS]: 12.4 vs 4.7 months, HR: 0.42, 95% CI 0.24-0.72 months). In the extension cohort, the independent review committee (IRC)-assessed objective response rate was 41.5% and CR rate was 38.7%; median IRC-assessed PFS and OS were 6.6 months and 12.5 months, respectively. No new safety signals with pola+BR were identified. Pola+BR is an effective treatment option for patients with R/R DLBCL, with a well-characterized and manageable safety profile.

PURPOSE Patients with relapsed or refractory primary mediastinal large B-cell lymphoma (rrPMBCL) have a poor prognosis, and their treatment represents an urgent and unmet need. Because PMBCL is associated with genetic aberrations at 9p24 and overexpression of programmed cell death-1 (PD-1) ligands (PD-L1), it is hypothesized to be susceptible to PD-1 blockade. METHODS In the phase IB KEYNOTE-013 (ClinicalTrials.gov identifier: NCT01953692 ) and phase II KEYNOTE-170 (ClinicalTrials.gov identifier: NCT02576990 ) studies, adults with rrPMBCL received pembrolizumab for up to 2 years or until disease progression or unacceptable toxicity. The primary end points were safety and objective response rate in KEYNOTE-013 and objective response rate in KEYNOTE-170. Secondary end points included duration of response, progression-free survival, overall survival, and safety. Exploratory end points included association between biomarkers and pembrolizumab activity. RESULTS The objective response rate was 48% (7 complete responses; 33%) among 21 patients in KEYNOTE-013 and 45% (7 complete responses; 13%) among 53 patients in KEYNOTE-170. After a median follow-up time of 29.1 months in KEYNOTE-013 and 12.5 months in KEYNOTE-170, the median duration of response was not reached in either study. No patient with complete response experienced progression, including 2 patients with complete response for at least 1 year off therapy. Treatment-related adverse events occurred in 24% of patients in KEYNOTE-013 and 23% of patients in KEYNOTE-170. There were no treatment-related deaths. Among 42 evaluable patients, the magnitude of the 9p24 gene abnormality was associated with PD-L1 expression, which was itself significantly associated with progression-free survival. CONCLUSION Pembrolizumab is associated with high response rate, durable activity, and a manageable safety profile in patients with rrPMBCL.

Abstract Background To examine the effect of prior use of cetuximab and neck dissection on the effectiveness of nivolumab, we conducted a large-scale subgroup analysis in Japanese patients with recurrent/metastatic head and neck cancer. Methods Data on the effectiveness of nivolumab were extracted from patient medical records. All patients were analyzed for effectiveness by prior cetuximab use. In the analyses for prior neck dissection, only patients with locally advanced disease were included. Results Of 256 patients analyzed, 155 had received prior cetuximab. Nineteen of 50 patients with local recurrence underwent neck dissection. The objective response rate was 14.7 vs 17.2% (p = 0.6116), median progression-free survival was 2.0 vs 3.1 months (p = 0.0261), and median overall survival was 8.4 vs 12 months (p = 0.0548) with vs without prior cetuximab use, respectively. The objective response rate was 23.1 vs 25.9% (p = 0.8455), median progression-free survival was 1.8 vs 3.0 months (p = 0.6650), and median overall survival was 9.1 vs 9.9 months (p = 0.5289) with vs without neck dissection, respectively. Conclusions These findings support the use of nivolumab for patients with recurrent/metastatic head and neck cancer regardless of prior cetuximab use or neck dissection history.

BackgroundThe indoleamine 2,3-dioxygenase (IDO) pathway is a key counter-regulatory mechanism that, in cancer, is exploited by tumors to evade antitumor immunity. Indoximod is a small-molecule IDO pathway inhibitor that reverses the immunosuppressive effects of low tryptophan (Trp) and high kynurenine (Kyn) that result from IDO activity. In this study, indoximod was used in combination with a checkpoint inhibitor (CPI) pembrolizumab for the treatment for advanced melanoma.MethodsPatients with advanced melanoma were enrolled in a single-arm phase II clinical trial evaluating the addition of indoximod to standard of care CPI approved for melanoma. Investigators administered their choice of CPI including pembrolizumab (P), nivolumab (N), or ipilimumab (I). Indoximod was administered continuously (1200 mg orally two times per day), with concurrent CPI dosed per US Food and Drug Administration (FDA)-approved label.ResultsBetween July 2014 and July 2017, 131 patients were enrolled. (P) was used more frequently (n=114, 87%) per investigator’s choice. The efficacy evaluable population consisted of 89 patients from the phase II cohort with non-ocular melanoma who received indoximod combined with (P).The objective response rate (ORR) for the evaluable population was 51% with confirmed complete response of 20% and disease control rate of 70%. Median progression-free survival was 12.4 months (95% CI 6.4 to 24.9). The ORR for Programmed Death-Ligand 1 (PD-L1)-positive patients was 70% compared with 46% for PD-L1-negative patients. The combination was well tolerated, and side effects were similar to what was expected from single agent (P).ConclusionIn this study, the combination of indoximod and (P) was well tolerated and showed antitumor efficacy that is worth further evaluation in selected patients with advanced melanoma.

Abstract To study and observe the safety and efficacy of anlotinib in the treatment of advanced osteosarcoma with metastases. We retrospectively studied patients with advanced osteosarcoma and metastases who received anlotinib treatment in our hospital from June 2018 to April 2020. All patients had received standard multimodal therapies, before taking anlotinib. Therapeutic doses of anlotinib were 12 mg for adults and 10 mg for children and adolescents once a day for 2 consecutive weeks, followed by a week of withdrawal. This 3-week cycle of treatment was continued until the tumor progressed rapidly or the patients failed to tolerate the side effects. Adverse drug reactions were recorded, and therapeutic efficacy was evaluated based on progression free survival (PFS), disease control rate (DCR), overall survival (OS), and objective response rate (ORR). The median PFS was 9.81 ± 0.9 months, and the 6-month and 10-month PFS rates were 73.3% and 33.3%, respectively. The median OS was 11.43 ± 0.58 months. No patients achieved complete response. After 6 months of treatment, the DCR and ORR were 80% and 13.3%, respectively. No drug-related deaths or Grade 4 adverse events occurred in the patients. Five patients (33.3%) had Grade 3 adverse events. The most common drug-related adverse events were hand-food syndrome, fatigue, high blood pressure, anorexia, and pneumothorax. Anlotinib had a certain curative effect on patients with advanced osteosarcoma and metastases after failure of standard treatment. The adverse events were mostly tolerable or relieved after treatment.

PURPOSE: To assess the safety and efficacy of vinorelbine in patients with AIDS-related Kaposi’s sarcoma (KS). PATIENTS AND METHODS: From December 1994 to May 1997, within the Italian Cooperative Group on AIDS and Tumors, we enrolled 36 patients with AIDS-related KS who experienced disease progression after one or more regimens of systemic chemotherapy. Patients were treated with vinorelbine 30 mg/m2 every 2 weeks by intravenous bolus. RESULTS: Of 35 assessable patients, three (9%) had a clinical complete response and 12 (34%) had a partial remission, for an overall objective response rate of 43% (95% confidence interval, 26% to 61%). For the 15 patients with objective responses, the median duration of response from the beginning of therapy until the development of progression was 176 days, whereas the median progression-free survival and the median survival durations for 35 assessable patients were 151 days and 216 days, respectively. Vinorelbine also induced responses in patients who had become resistant to regimens that included other vinca alkaloids. Overall, vinorelbine was well tolerated. Toxicity, including neurologic toxicity, was mild and reversible. Neutropenia was the most frequent dose-limiting toxicity. CONCLUSION: Vinorelbine is safe and effective in the treatment of patients with advanced KS who have been previously treated with one or more chemotherapy regimens.

Purpose Venetoclax is an orally bioavailable B-cell lymphoma 2 inhibitor. US Food and Drug Administration and European Medicines Agency approval for patients with 17p deleted relapsed/refractory chronic lymphocytic leukemia [del(17p) CLL] was based on results from 107 patients. An additional 51 patients were enrolled in a safety expansion cohort. Extended analysis of all enrolled patients, including the effect of minimal residual disease (MRD) negativity on outcome, is now reported. Patients and Methods Overall, 158 patients with relapsed/refractory or previously untreated (n = 5) del(17p) CLL received venetoclax 400 mg per day after an initial dose ramp up. Responses were based on 2008 International Workshop on Chronic Lymphocytic Leukemia criteria, with monthly physical exams and blood counts. Computed tomography scan was mandatory at week 36, after which assessment made was by clinical evaluation. Marrow biopsy was performed when complete remission was suspected. MRD was assessed by flow cytometry. Results Patients had a median of two prior therapies (range, zero to 10 therapies), 71% had TP53 mutation, and 48% had nodes that were ≥ 5 cm. Median time on venetoclax was 23.1 months (range, 0 to 44.2 months) and median time on study was 26.6 months (range, 0 to 44.2 months). For all patients, investigator-assessed objective response rate was 77% (122 of 158 patients; 20% complete remission) and estimated progression-free survival at 24 months was 54% (95% CI, 45% to 62%). For 16 patients who received prior kinase inhibitors, objective response rate was 63% (10 of 16 patients) and 24-month progression-free survival estimate was 50% (95% CI, 25% to 71%). By intent-to-treat analysis, 48 (30%) of 158 patients achieved MRD below the cutoff of 10−4 in blood. Common grade 3 and 4 adverse events were hematologic and managed with supportive care and/or dose adjustments. Conclusion Venetoclax achieves durable responses and was well tolerated in patients with del(17p) CLL. A high rate of blood MRD < 10−4 was achieved in this high-risk population.

Abstract This study evaluated the efficacy and safety of single-agent bortezomib in indolent B-cell lymphoma that had relapsed from or was refractory to rituximab. Sixty patients enrolled: 59 were treated with bortezomib 1.3 mg/m2 on days 1, 4, 8, and 11 for up to eight 21-day cycles; responders could receive 4 additional cycles; maintenance was optional. Fifty-three evaluable patients completed more than 2 cycles. The median age was 70 years, 53% female, Ann Arbor stage III-IIIE (28%) and IV (65%); 43 patients (72%) had more than 2 prior regimens; and 6 patients went on to maintenance. Overall responses are as follows: 1 complete response (1.9%), 3 unconfirmed complete response (5.7%), 3 partial response (5.7%), 34 stable disease (64.2%), and 12 progressive disease (22.6%). Median time to response = 2.2 months (range, 1.2-5.3 months); duration of response = 7.9 months (2.8-21.3 months); 1-year survival was 73% and 2-year survival was 58%; median survival = 27.7 months (range, 1.4-30.9 months); median progression-free survival = 5.1 months (range, 0.2-27.7 months), median time to progression = 5.1 months (range, 0.2-27.7 months), and median event-free survival = 1.8 months (range, 0.2-27.7 months). Treatment-related grade 3 or 4 adverse events included: thrombocytopenia (20%), fatigue (10%), neutropenia (8.5%), and neuropathy and diarrhea (6.8% each). This study demonstrates that bortezomib has modest activity against marginal zone and follicular lymphoma; it has the potential for combination with other agents in low-grade lymphomas. Maintenance therapy should be explored further.

9013 Background: Dabrafenib is a selective BRAF inhibitor with demonstrated efficacy in BRAF V600E-positive mutation in MM. The primary analysis of BREAK-3 (NCT01227889) compared progression-free survival (PFS) in patients (pts) with BRAF V600E-positive mutation MM treated with dabrafenib or DTIC. Methods: Median PFS for dabrafenib of 5.1 months (mo) and study methods were previously described (Hauschild A, et al. Lancet. 2012,380:358–365). Independent review ended at the primary analysis. PFS was updated in Jun 2012 at median follow-up of 10.5 mo for dabrafenib (67% of PFS events), and 9.9 mo for DTIC. Median overall survival (OS) was not reached, so another analysis of OS and safety was performed with data as of Dec 2012, at which time the median follow-up was 15.2 (dabrafenib) and 12.7 (DTIC) mo. PFS of subjects who crossed over was also evaluated at that time. Results: PFS hazard ratio was 0.37 [95% CI; 0.23, 0.57]; median PFS was 6.9 mo dabrafenib and 2.7 mo DTIC. In Dec 2012, 36/63 DTIC pts crossed over; median PFS was 4.3 [95% CI; 4.1, 6.1] mos. OS is presented in the Table.The four most common adverse events (AE) on the dabrafenib arm were hyperkeratosis (39%), headache (35%), arthralgia (35%), and pyrexia (32%). Serious AEs ≥ 5% on the dabrafenib arm included cutaneous squamous cell carcinoma/keratoacanthoma (10%) and pyrexia (5%). Conclusions: Longer follow-up confirms the benefits of dabrafenib on PFS and response rate. Median OS in the dabrafenib arm was over 18 mo and over 15 mo in the DTIC arm. OS results are confounded by crossover of DTIC pts to dabrafenib and likely by subsequent therapy after progression. The effects of subsequent therapy results will be investigated. The safety profile had no significant changes. Clinical trial information: NCT01227889. [Table: see text]

613 Background: BMI has been explored as a prognostic factor in cancer pts and treatment-related toxicities have been associated with responses to VEGF-targeted therapy in mRCC pts. We investigated the association of BMI and adverse events (AEs) and CO in mRCC pts treated with cabo. Methods: A retrospective analysis of 65 pts with mRCC treated with cabo at Winship Cancer Institute from 2016 to 2018 was performed. Overall survival (OS), progression-free survival (PFS), and objective response (OR) were used to measure CO. OS and PFS were calculated from first cabo dose to death and radiographic or clinical progression, respectively. An OR was defined as a partial response (PR) or a complete response (CR) using RECISTv1.1. BMI was collected at baseline (BL) and 6 (±2) weeks after cabo initiation. AEs were obtained from clinic notes. Univariate analysis (UVA) of association between BMI and CO was carried out using logistic regression model for OR and proportional hazard model for OS and PFS. Results: The median age was 63 years and 26% were African American. The majority were either IMDC intermediate or poor-risk (59% and 34%, respectively). Most pts (67%) had a BMI ≥ 25 and the median BMI at BL was 26.6. There was no difference in incidence of AEs between pts with BMI < 25 and pts with BMI ≥ 25. Gastrointestinal (GI) AEs incidence was also comparable among pts with a BMI ≥ 25 (62%) and pts with BMI < 25 (57%, p = 0.666). Increased BMI at 6W was significantly associated with prolonged OS and increased baseline BMI at BL showed a trend towards longer OS (Table). Conclusions: Increased BMI may be associated with improved CO in mRCC pts treated with cabo, but there may not be a difference in AEs based on BMI. Larger analyses are needed to validate these findings. [Table: see text]

4040 Background: In the phase 2 CheckMate 142 trial, NIVO + low-dose IPI had robust, durable clinical benefit and was well tolerated as 1L therapy for MSI-H/dMMR mCRC (median follow-up 13.8 months [mo; range, 9–19]; Lenz et al. Ann Oncol 2018;29:LBA18). Longer follow-up is presented here. Methods: Patients (pts) with MSI-H/dMMR mCRC and no prior treatment for metastatic disease received NIVO 3 mg/kg Q2W + low-dose IPI 1 mg/kg Q6W until disease progression or discontinuation. The primary endpoint was investigator-assessed (INV) objective response rate (ORR) per RECIST v1.1. Results: In 45 pts with median follow-up of 29.0 mo, ORR (95% CI) increased to 69% (53–82) (Table) from 60% (44.3–74.3); complete response (CR) rate increased to 13% from 7%. The concordance rate of INV and blinded independent central review was 89%. Median duration of response (DOR) was not reached (Table). Median progression-free survival (PFS) and overall survival (OS) were not reached, and 24-mo rates were 74% and 79%, respectively (Table). Nineteen pts discontinued study treatment without subsequent therapy. An analysis of tumor response post discontinuation will be presented. Ten (22%) pts had grade 3–4 treatment-related adverse events (TRAEs); 3 (7%) had grade 3–4 TRAEs leading to discontinuation. Conclusions: NIVO + low-dose IPI continued to show robust, durable clinical benefit with a deepening of response, and was well tolerated with no new safety signals identified with longer follow-up. NIVO + low-dose IPI may represent a new 1L therapy option for pts with MSI-H/dMMR mCRC. Clinical trial information: NTC02060188 . [Table: see text]
