17569 Background: Lenalidomide is an immunomodulatory drug of the IMiD class that has activity in multiple myeloma, myelodysplastic syndromes and chronic lymphocytic leukemia. We report preliminary results of two Phase II studies assessing the safety and efficacy of lenalidomide monotherapy in subjects with relapsed/refractory indolent or aggressive non-Hodgkin’s lymphoma (NHL). Methods: Subjects with indolent (study NHL-001) or aggressive (study NHL-002) relapsed/refractory NHL following ≥ 1 prior treatment regimen with measurable disease are eligible. Subjects receive 25 mg lenalidomide orally once daily on Days 1–21 every 28 days and continue therapy for 52 weeks as tolerated until disease progression. Response and progression are evaluated using cross sectional imaging by the NCI criteria. Results: 10 subjects (2 indolent (I), 8 aggressive (A)) of a planned 80 (40 in each study) have enrolled thus far. Median age is 66 (45–80) and 7 subjects are female. Indolent histology is follicular center lymphoma grade 1, 2 (n = 2) and aggressive histology diffuse large cell lymphoma (n = 7) and follicular center lymphoma grade 3 (n = 1). Median time from diagnosis to lenalidomide monotherapy is 2.9 years (1.1–10) and median number of prior treatment regimens per subject is 3 (1–6). Median duration of follow-up is 2 months. Of eight subjects (2 I, 6 A) evaluable for response at two months, three demonstrated a decrease in their tumor burden by 72% (I), 68% (A) and 52% (A), two subjects (2 A) exhibited stable disease and three subjects (1 I, 2 A) had disease progression. Six of the ten subjects (2 I, 4 A) demonstrated no Grade 3 or 4 adverse events. Grade 3 or 4 hematological adverse events (neutropenia, thrombocytopenia) occurred in four subjects including one febrile neutropenia and one of these four subjects also exhibited Grade 3 cellulitis. No tumor flare or tumor lysis has been observed to date. Conclusions: Preliminary data of lenalidomide monotherapy in relapsed and refractory NHL are encouraging. [Table: see text]

e19540 Background: Bendamustine plus rituximab (B+R) was established as a preferred first line therapy for patients with previously untreated indolent non-Hodgkin’s lymphoma based on the BRIGHT and STIL trials. However, only few reports on efficacy and safety data of this combination in the real-world setting are available to-date. Methods: We conducted a retrospective review of patients who received therapy with standard doses of B+R in our cancer center from June 2013 to January 2021. Patients with indolent non-Hodgkin’s lymphoma (iNHL) and mantle cell lymphoma (MCL) who received more than one cycle of B+R were evaluated. Results: Amongst a total of 201 patients 56% were males and 44% females. Median age at B+R initiation was 72 years (range 34-94). Follicular lymphoma (FL) (50.3%), marginal zone lymphoma (MZL) (19.4%), and lymphoplasmacytic lymphoma (LPL) (14.5%) were the most common iNHL. Stage 3 and 4 diseases represented 19.9% and 68.6% of patients. Extranodal disease was found in 35.8%. The proportion of patients with high risk disease was 48.5% for FL (FLIPI ≥3), 86.6% for LPL (WMISS score ≥2), and 80.5% for MCL (MIPI score ≥6.2). Prior history of secondary malignancy had 23.4% of patients; 11.4% patients had ECOG 3. Most common indications for B+R initiation were bulky symptomatic lymphadenopathy (69.1%), cytopenia (36.8%) and constitutional symptoms (36.8%). Fifty-eight percent of patients had more than one indication for therapy. Median number of B+R cycles delivered was 6 (range: 1-6), median dose of bendamustine was 90 mg/m2 (range 45-90). Full doses of treatment were given in 66.7% of patients, reduced in 33.3% with mean dose 78.3 mg/m2. A total of 50.8% completed 6 cycles with no delays, in 49.2% treatment was delayed (mean delay time 1.8 weeks). Overall response was 94.5%, with 77.6% complete and 16.9% partial remission. Median duration of follow-up was 35 months (range: 4-91). At the end of follow-up, event free survival (EFS) was 77.1% and overall survival (OS) was 79.6%. Six percent of patients relapsed, 8% developed secondary hematological malignancies, including 14 cases of aggressive B-cell lymphoma and 2 cases of MDS. 16.9% of patients required support with G-CSF. Grade 3-4 neutropenia was recorded in 22.4%, febrile neutropenia in 7.5%, grade 3-4 anemia in 7.9%, and grade 3-4 thrombocytopenia in 3.9% of patients. Rituximab-associated infusion reactions, skin rash, thrombophlebitis, and infection were the most common non-hematological adverse events. A total of 80.6% of patients proceeded to rituximab maintenance. Conclusions: B+R chemoimmunotherapy is feasible to administer in non-clinical trial setting. Despite more dose reduction as compared to STIL trial, B+R retained its efficacy with comparable EFS and OS. No new adverse events or increase in secondary malignancies were found.

PURPOSE: Two phase I studies of the oxaliplatin and irinotecan combination were performed in advanced gastrointestinal cancer patients to characterize the safety and pharmacokinetics of the regimen. PATIENTS AND METHODS: Patients with a performance status (PS) of ≤2 and normal hematologic, hepatic, and renal functions received oxaliplatin (2-hour intravenous infusion) followed 1 hour later by irinotecan administered over a 30-minute period, every 3 weeks. Dose levels that were explored ranged from 85 to 110 mg/m2 for oxaliplatin and 150 to 250 mg/m2 for irinotecan. Plasma pharmacokinetics of total and ultrafiltrable platinum, irinotecan, SN-38, and its glucuronide, SN-38G, were determined. RESULTS: Thirty-nine patients with gastrointestinal carcinomas (24 with colorectal cancer [CRC], four with pancreas cancer, four with gastric cancer, three with hepatocarcinoma, and four with other) received 216 treatment cycles. Median age was 54 years (range, 21 to 72 years); 95% had PS of 0 to 1; all but six had failed fluorouracil (5-FU) chemotherapy. The maximum-tolerated dose was oxaliplatin 110 mg/m2 plus irinotecan 200 mg/m2 in one study and oxaliplatin 110 mg/m2 plus irinotecan 250 mg/m2 in the other study. Grade 3 to 4 diarrhea and febrile neutropenia were dose-limiting toxicities; other toxicities included emesis and dose-cumulative neuropathy. Recommended dose for phase II studies is oxaliplatin 85 mg/m2 and irinotecan 200 mg/m2. At this dose (12 patients, 65 cycles), grade 3 and 4 toxicities per patient included the following: emesis in 42% of patients, neutropenia in 33% (febrile episodes in 17%), peripheral neuropathy in 25%, delayed diarrhea in 17%, and thrombocytopenia in 8%. Two patients with Gilbert's syndrome experienced severe irinotecan toxicity. No plasmatic pharmacokinetic interactions were detected. Seven partial responses were observed in 24 CRC patients. CONCLUSION: This combination is feasible, with activity in 5-FU–resistant CRC patients. Phase I studies that explore the every-2-weeks schedule, in addition to phase II studies of this schedule (as well as in combination with 5-FU) as second-line therapy of metastatic CRC, are ongoing.

PurposeThe major cause of death in aggressive lymphoma is relapse or nonresponse to initial therapy. Lenalidomide has activity in a variety of hematologic malignancies, including non-Hodgkin's lymphoma (NHL). We report the results of a phase II, single-arm, multicenter trial evaluating the safety and efficacy of lenalidomide oral monotherapy in patients with relapsed or refractory aggressive NHL.Patients and MethodsPatients were treated with oral lenalidomide 25 mg once daily on days 1 to 21, every 28 days, for 52 weeks, until disease progression or intolerance. The primary end point was response; secondary end points included duration of response, progression-free survival (PFS), and safety.ResultsForty-nine patients with a median age of 65 years received lenalidomide in this study. The most common histology was diffuse large B-cell lymphoma (53%), and patients had received a median of four prior treatment regimens for NHL. An objective response rate of 35% was observed in 49 treated patients, including a 12% rate of complete response/unconfirmed complete response. Responses were observed in each aggressive histologic subtype tested (diffuse large B-cell, follicular center grade 3, mantle cell, and transformed lymphomas). Of patients with stable disease or partial response at first assessment, 25% improved with continued treatment. Estimated median duration of response was 6.2 months, and median PFS was 4.0 months. The most common grade 4 adverse events were neutropenia (8.2%) and thrombocytopenia (8.2%); the most common grade 3 adverse events were neutropenia (24.5%), leukopenia (14.3%), and thrombocytopenia (12.2%).ConclusionOral lenalidomide monotherapy is active in relapsed or refractory aggressive NHL, with manageable side effects.

Abstract Objective: The objective of this study was to evaluate the efficacy and safety of bendamustine HCl (TREANDA®) in combination with rituximab in patients with relapsed non-Hodgkin’s lymphoma (NHL). Background: Bendamustine is a novel hybrid, alkylating agent with single-agent activity in multiple hematologic and solid tumors. It induces cell death via both apoptosis and the apoptosis-independent pathway of mitotic catastrophe. The combination of bendamustine and rituximab has been shown to exhibit a synergistic antitumor effect on NHL cells. Methods: This Phase II, multicenter study enrolled adult patients with relapsed, indolent B-cell or mantle-cell NHL who were not refractory to rituximab (defined as progression ≤6 months of last rituximab dose). Patients received rituximab 375 mg/m2 intravenously (IV) on day 1 and bendamustine 90 mg/m2 IV on days 2 and 3 of a 28-day cycle for 4 to 6 cycles. An additional dose of rituximab 375 mg/m2 IV was given 1 week before the first cycle of bendamustine and 4 weeks after the last cycle. Results: The intent-to-treat (ITT) population included 66 patients (59% men) with a median age of 60 years (range, 40–84). Indolent histologic phenotype was seen in 54 patients with the following histologic subtypes: follicular center cell (61%), small lymphocytic (15%), lymphoplasmacytic (3%), and marginal zone (3%); 18% had mantle-cell lymphoma (MCL). A total of 85% of patients had stage III/IV disease. These patients relapsed from a median of 1 prior chemotherapy (range: 0–5), with 56% having had prior treatment with rituximab. Patients with no prior chemotherapy relapsed following biologic therapy. In the ITT population, the overall objective response rate (ORR) was 94% (complete response [CR]/complete response unconfirmed [CRu], 41%; partial response [PR], 53%); 6% had stable disease. The ORR for the 12 MCL patients was 92% (CR/CRu, 42%; PR 50%). For all patients, the median duration of response and progression-free survival has not been reached after a median follow-up of 8.3 months (range, 0.14–31 months). Grade 3/4 neutropenia was seen in 41% of patients (7%, febrile neutropenia). Common nonhematologic toxicities (grade 1/2, grade 3, grade 4) were nausea (68%, 0%, 0%) and fatigue (53%, 5%, 0%); one patient had grade 3 sepsis. No alopecia was observed. Conclusions: Bendamustine administered in combination with rituximab produced a high objective response rate and was generally well tolerated in patients with relapsed indolent and mantle-cell NHL who were not refractory to rituximab. These results suggest that the combination of bendamustine and rituximab may be comparable in activity to R-CHOP, and further studies of this combination are warranted.

Abstract Background: Lenalidomide (Revlimid®), an immunomodulatory drug (IMiD®), was recently approved in the US for treatment of relapsed/refractory multiple myeloma and myelodysplastic syndromes associated with a deletion 5q[31] cytogenetic abnormality. Lenalidomide also has demonstrated activity in chronic lymphocytic leukemia and cutaneous T-cell lymphoma while thalidomide, a less potent IMiD®, has activity in non-Hodgkin’s lymphoma as both monotherapy and in combination with rituximab. Aim: To assess the safety and activity of lenalidomide monotherapy in subjects with relapsed/refractory aggressive non-Hodgkin’s lymphoma (NHL). Methods: Subjects with relapsed/refractory aggressive NHL following at least 1 prior treatment regimen with measurable disease are eligible. Subjects receive 25 mg lenalidomide orally once daily on Days 1–21 every 28 days and continue therapy for 52 weeks as tolerated or until disease progression. Response and progression are evaluated using the IWLRC methodology. Results: As of July 25, 2006, 32 subjects of a planned 40 have enrolled and 31 have received drug. Twenty-two subjects are currently evaluable for tumor response. The median age of the 22 response-evaluable subjects is 65 (46–83) and 13 are female. Histology is diffuse large B-cell lymphoma [DLBCL] (n=12), follicular center lymphoma grade 3 [FL] (n=3), mantle cell lymphoma [MCL] (n=5) and transformed [TSF] (n=2). Median time from diagnosis to lenalidomide monotherapy is 2.3 (0.7–7) years and median number of prior treatment regimens per subject is 2 (1–6). Seven subjects (32%) exhibited an objective response (2 complete responses unconfirmed (CRu) and 5 partial responses (PR)), 6 had stable disease (SD) for a tumor control rate (TCR) of 59% and 9 progressive disease (PD). Responses were produced in each of the aggressive histologic subtypes studied: DLBCL (3/12), FL (1/3), MCL (2/5) and TSF (1/2). Five of 11 subjects (45%) with 1–2 prior treatment regimens had an objective response, as did 2 of 3 subjects (67%) who had received a prior stem cell transplant. Median time-to-response was 2 months. Grade 3 or 4 adverse events occurred in 18 of 31 (58%) subjects receiving drug. These were predominantly Grade 3 hematological events (neutropenia, thrombocytopenia) with only 4 subjects (13%) experiencing a Grade 4 adverse reaction. Conclusion: Preliminary results indicate that lenalidomide monotherapy is active with manageable side effects in relapsed/refractory aggressive NHL.

560 Background: The safety and efficacy of first-line XELIRI (capecitabine in combination with irinotecan) and XELIRI plus bevacizumab (BEV) have been evaluated in patients with metastatic colorectal cancer (mCRC). To date, however, no randomized studies comparing these regimens have been performed. This retrospective analysis compared efficacy and safety data for the two regimens from separate phase II studies performed at a single institution. Methods: Patients with histologically documented metastatic or recurrent CRC and no prior treatment for advanced disease received irinotecan 175 mg/m2 on day 1 and oral capecitabine 1,000 mg/m2 twice daily on days 2-8 every 2 weeks (XELIRI study). For patients age ≥65 years, the starting doses of irinotecan and capecitabine were reduced to 140 mg/m2 and 750 mg/m2, respectively. In the second study, patients received the same regimen plus BEV 5 mg/kg on day 1 (XELIRI + BEV study). Results: A total of 53 and 46 patients were entered into the XELIRI and XELIRI + BEV studies, respectively. Patient characteristics were generally similar in both groups. Efficacy results for the ITT populations are summarized in the Table. Patients treated with XELIRI + BEV had a significantly higher ORR and longer median TTP vs. XELIRI alone and a numerically longer median OS was observed (p=NS). The overall incidence of adverse events (all grades or grade 3/4) was similar in the two groups, although alopecia, mucositis, hand–foot syndrome, and haemorrhage were more common with XELIRI + BEV vs. XELIRI alone (all p<0.05). Conclusions: In this retrospective comparison of two studies, the addition of BEV to XELIRI appeared to improve outcome relative to XELIRI alone in the first-line treatment of patients with mCRC. The overall incidence of adverse events was similar in the two groups. [Table: see text] No significant financial relationships to disclose.

4109 Background: Retrospective data in some cancer types suggested a possible different toxicity profile with chemotherapy and targeted therapies according to gender. However, data from prospective studies are still very limited, especially in infrequent tumors such as NETs. Methods: Pts with advanced pancreatic and gastrointestinal NETs treated with pazopanib or lenvatinib in the multicenter open-label phase II studies PAZONET and TALENT respectively, were included in the analysis. Both studies were performed by Spanish Task Force Group for Neuroendocrine Tumors (GETNE). All toxicity grades with an incidence higher than 5% were considered for univariate review. Additionally, all grade 3-4 toxicities were analyzed separately. Results: 155 pts (47.7% female) with 1213 adverse events (AEs) (20% G3-4) divided in 121 categories were included. In female patients, liver toxicity, headache, pyrexia, nausea/vomiting, hair/skin disorders and dizziness were significantly more common (table). The only toxicity with higher incidence in men was dysphonia (OR 0.42, 95% CI 0.2-0.9, p 0.02). There were no gender differences in grade 3-4 toxicities. Conclusions: We observed significant differences in toxicity AEs by gender in two prospective phase II studies with MKIs in NETs patients. Potential different approach to manage toxicity may be adopted based on gender. [Table: see text]

e19519 Background: Gemcitabine, vinorelbine and liposomal doxorubicin (GVD) is an effective regimen in relapsed/refractory Hodgkin’s lymphoma (RRHL). Conventional second-line chemotherapy is still required as the cost of immunotherapy and antibody-drug conjugates are prohibitive to Indian patients. We report the results of a phase II, open-label, single-arm, single centre interventional study in RRHL where dexamethasone replaced liposomal doxorubicin. Methods: Adult patients (≥18 years) with RRHL at first or second relapse were included. GVDex was delivered as outpatient once in 3 weeks (Gemcitabine 1000 mg/m2 IV over 30 min on D1,8; Vinblastine 25 mg/m2 IV fast infusion on D1,8; Dexamethasone 40 mg PO D1-4) for two cycles followed by interim PET CT assessment by Cheson’s criteria and Deauville scoring. The primary endpoint was the objective response rate (ORR = complete response + partial response). The sample size was calculated using Fleming’s 2-stage model (α error: 0.05 and power: 0.8). Twenty patients were required in the first stage. If there were ≥16 responses, the null hypothesis would be rejected and the study stopped. Results: Between May 2016, and December 2020, 26 patients with RRHL were screened, and 20 were enrolled: primary resistant HL-8 patients (40%) and relapsed HL- 12 patients (60%). The median age was 35 years (range:20-52). Six patients (30%) presented with limited stage and 14 patients (70%) with advanced stage HL at relapse. GVdex was delivered as a first salvage regimen in 18 patients (90%) and second in 2 patients. After 2 cycles of GVDex, 16 (80%) had responded [partial response: 12 (60%); complete response: 4 (20%)]. Median number of cycles of GVDex: 3 (range: 1-4). Five patients (25%) required dose reductions due to chemotherapy-related toxicities. The median duration of objective response was 13.4 months. Eleven patients (55%) underwent high-dose chemotherapy supported by autologous stem cell rescue. After a median follow-up of 25 months (95% CI: 5.9-44.5), the median progression-free survival (PFS) was 24.7 months, and the median overall survival (OS) has not been reached. The estimated 2-year PFS was 44%, and the 2-year OS was 79%. The most common treatment-related adverse events were anemia (100%), neutropenia (70%, 14/20) and fatigue (70%, 14/20). Grade 3 or 4 treatment-related AEs occurred in 14 patients (70%). Grade ≥3 neutropenia occurred in 9 patients (45%) and febrile neutropenia in 3 patients (15%). Serious adverse events were reported in 3 patients (15%). One patient developed Ficat and Arlet classification stage III avascular necrosis of the femoral head. One patient died due to suspected COVID-19 pneumonia (non-neutropenic fever) before cycle 2 of chemotherapy. Conclusions: GVDex it is an effective salvage regimen with acceptable toxicity in patients with RRHL. Clinical trial information: CTRI/2017/04/008361.
