PURPOSE: Ipilimumab is an effective treatment for melanoma; however, toxicity rates remain high. The objective of this study was to describe the rates of adverse events (AEs), emergency room (ER) visits, hospitalizations, and nursing resource utilization for patients enrolled in a nurse-led telephone toxicity monitoring program. METHODS: Patients received weekly telephone calls from nursing to review a toxicity checklist during ipilimumab treatment and for 8 weeks after completion. To evaluate this program, a single-center retrospective review was performed for patients treated between July 2012 and September 2017 with single agent ipilimumab for advanced melanoma. Data were collected up to 3 months post-ipilimumab. RESULTS: A total of 67 patients were included, with a mean (standard deviation) age of 61 (14.6) years. Thirty-three (49%) patients received four doses of ipilimumab, and 17 (25%) had one dose delay. The median (IQR) of any AEs reported per patient was 11 (8-17). There were 44 (66%) patients with AEs deemed to be definitely or probably related to ipilimumab, and of those, 3 (4%) experienced a grade 3 AE, whereas 4 (6%) experienced grade 4 AEs. Twenty patients (30%) had ER visits, and 31 (46%) were hospitalized during follow-up (9% ER visits and 6% hospitalizations were related to drug toxicity). CONCLUSION: Ipilimumab is associated with high rates of toxicity; however, a proactive nurse-led monitoring program was feasible and patients had low rates of grade 3-4 toxicity. Hospitalization rates and ER visits remained high; however, the minority of those were related to drug toxicity.

e16184 Background: Hepatic derangement commonly accompanies advanced HCC (aHCC) and limits the use of systemic therapies. We aimed to evaluate the use of single agent anti-PD-1 nivolumab or pembrolizumab in Child-Pugh (CP) grade B or C patients with aHCC. Methods: Consecutive aHCC patients with CP grade B (CPB) or C (CPC) liver function who received single agent nivolumab or pembrolizumab were analysed. Objective response rate (ORR), time-to-progression (TTP), overall survival (OS), and treatment-related adverse events (TRAEs) were assessed. Results: Between May 2015 and June 2020, 61 patients were included. The median age was 60 (range 28-82). 81% and 4.8% had hepatitis-B and hepatitis-C related HCCs respectively. 72.1% (n = 44) were of CPB and 27.9% (n = 17) were of CPC. Amongst CPB patients, 19 (31.1% of all patients) had CP score 7 (CP7) and 25 (41.0% of all patients) had CP score 8 or 9. The median follow-up was 2.3 months. The ORR of CPB and CPC patients were 6.8% and 0% respectively (p = 0.553). The TTP of CPB and CPC patients were 2.1 months (95% C.I. 1.4-2.8) and 1.4 months (95% C.I. 0.6-2.1) respectively (p = 0.204). CPB patients had significantly better OS than CPC patients (3.1 months (95% C.I. 1.4-4.7), vs. 1.7 months (95% C.I. 1.0-2.4), p = 0.041). Compared to CP score ≥8 (CP≥8) patients, CP7 patients had significantly better OS (median OS CP7 6.7 months (95% C.I. 4.0-9.3), vs. CP≥8 1.8 months (1.2-2.4), p = 0.002). Patients with diuretic-refractory ascites had significantly worse OS compared to those without (1.7 months (95% C.I. 1.0-2.5) vs. 3.7 months (95% C.I. 0.1-7.3), p = 0.004). Portal vein (PV) thrombosis was also significantly associated with inferior survival, with median OS of patients with any PV thrombosis being 1.8 months (95% C.I. 1.0-2.5), compared to 5.3 months (95% C.I. 2.4-8.1) of those without (p = 0.004). The median number of doses given was 3 (range 1-34). Median treatment duration was 5.0 weeks (range 0-77). Overall, 25.4% of patients experienced TRAEs and 4.8% experienced grade ≥3 TRAEs. The most common TRAEs were skin-related (13.1%) and constitutional symptoms (6.6%). Conclusions: Nivolumab/pembrolizumab had acceptable safety in CPB/C patients with aHCC. CP7, absence of diuretic-refractory ascites and lack of PV thrombosis were associated with better survival.

Abstract Langerhans-cell histiocytosis (LCH) results from the accumulation of tissue histiocytes derived from the same progenitor cells as monocytes. Because cladribine is potently toxic to monocytes, we conducted a phase II trial of cladribine. Cladribine was administered to 13 LCH patients at 0.14 mg/kg per day by 2-hour intravenous infusion for 5 consecutive days, every 4 weeks for a maximum of six courses. Median age was 42 years (range, 19 to 72) and median pretreatment disease duration was 99 months (range, 6 to 252). One patient was untreated, one had received prior prednisone only, one prior radiation only, six prior radiation and chemotherapy, and four prior surgery, radiation, and chemotherapy. Seven patients had cutaneous involvement, six multifocal osseous, six pulmonary, two each with soft tissue and nodal involvement, and four had diabetes insipidus. Of 13 patients, 12 were evaluable for response and all for toxicity. After a median of three courses (range, 1 to 6), seven (58%) patients achieved complete responses (two pathologic and five clinical) and two (17%) patients achieved partial responses; overall response rate, 75%. Median response follow-up duration was 33 months (range, 1 to 65). Seven patients experienced grade 3 to 4 neutropenia. Only one patient had a documented infection, dermatomal herpes zoster. At a median follow-up of 42 months (range, 5 to 76), 12 patients remain alive and one patient has died. Thus, cladribine has major activity in adult LCH and warrants further investigation in both pediatric and adult LCH as a single agent and in combination with other drugs.

4519 Background: INDUCE-1 is a first-in-human trial evaluating fela, an IgG4 ICOS agonist non-T-cell depleting mAb, as monotherapy (mono) and in combo with P. ECs include tumor types, such as UC, with high ICOS expression and immunotherapy-favorable features. Fela induced IFNγ, increased PD-1/L1 expression, and enhanced antitumor activity in combo with PD-1 blockade nonclinically. We report preliminary efficacy, safety, and biomarker data of fela ± P in INDUCE-1 UC ECs. Methods: Eligible patients (pts) had recurrent/metastatic (R/M) UC of the upper or lower urinary tract, ≤6 prior systemic therapy lines in the advanced setting, measurable disease, and no active autoimmune disease. Pts received 0.3 or 1 mg/kg fela (mono EC; anti-PD-1/L1–experienced [exp] pts) or 0.3 mg/kg fela + 200 mg P (combo EC; anti-PD-1/L1–naïve pts) every 3 wks, up to 35 cycles until disease progression or unacceptable toxicity. Disease was assessed every 9 wks through wk 54, then every 12 wks. Archival and/or fresh biopsy tumor tissue was collected for biomarker analyses and safety assessed. Results: By Nov 6 2020, 13 anti-PD-1/L1–exp and 32 anti-PD-1/L1–naïve pts were evaluable in the mono and combo ECs, respectively. In the mono EC, median age was 69 yrs (range: 47–82), 92% of pts were male, and 85% received ≥2 prior therapy lines in the metastatic setting. In the combo EC, median age was 70 yrs (range: 42–84), 75% of pts were male, and 72% received ≥1 prior therapy line in the metastatic setting. In the mono EC, median duration of follow-up (mDoF) was 10.6 mo (range: 1.1–22.8); overall response rate (ORR) was 8% (1 partial response [PR]; 95% CI: 0.2, 36.0) with a duration of response (DoR) of 6.1 mo; disease control rate (DCR [response or stable disease for ≥9 wks]) was 23% (95% CI: 5.0, 53.8), and median overall survival (mOS) was 14.5 mo (95% CI: 2.8, NR), with 74% of pts alive at 6 mo. In the combo EC, mDoF was 9.6 mo (range: 0.9–28.3); ORR was 22% (7 PRs; 95% CI: 9.3, 40.0) with a median DoR of 8.3 months (range: 3.5–23.3+); DCR was 63% (95% CI: 43.7, 78.9), and mOS was 10.7 mo (95% CI: 5.2, 18.1), with 64% of pts alive at 6 mo. Grade ≥3 treatment-related AEs were reported for 0% and 9% of pts in the mono (N = 16) and combo (N = 44) safety populations, respectively. PD-L1 expression and ICOS-specific biomarkers are being evaluated, with promising trends observed in enrichment of clinical activity in preliminary analyses. Conclusions: Fela is the first ICOS agonist with reported single-agent activity in anti-PD-1/L1–exp relapsed/refractory UC. Fela + P in combo shows promising clinical activity and manageable safety in PD-1/L1–naïve R/M UC. Further study is warranted. Updated data to be presented.

Abstract Background Immunomodulatory drugs (IMiD), such as thalidomide and lenalidomide (LEN) and its newest derivative pomalidomide (POM), have shown great promise for the treatment of multiple myeloma (MM) patients (pts). POM has in vitro anti-MM potency and has shown efficacy for the treatment of relapsed/refractory (RR) MM pts. POM with dexamethasone (DEX) induces responses even for MM pts who are refractory to bortezomib (BORT) and LEN (Richardson et al, 2012). Pegylated liposomal doxorubicin (PLD) with BORT is FDA-approved for the treatment of MM pts who have received one prior therapy not containing BORT. The combination of PLD and LEN or thalidomide has shown efficacy for both RR and frontline MM pts (Offidani et al, 2006; 2007). We have also demonstrated that both the efficacy and tolerability of LEN in combination with DEX, PLD and BORT (DVD-R) may be improved by changing the doses and schedules of these drugs (Berenson et al, 2012). Based on these results, we hypothesized that the combination of POM, DEX and PLD would be effective for the treatment of RRMM pts. Thus, we conducted the first study investigating the safety and efficacy of POM in combination with intravenous (IV) DEX and PLD as a phase 1/2 trial using a modified dose, schedule and longer 28-day cycles for pts with RRMM. Methods The phase 1 portion enrolled MM pts w/ progressive disease whereas those enrolled in phase 2 also had to be refractory to LEN (single-agent or in combination), as demonstrated by progressive disease while receiving their last LEN-containing regimen or relapsed within 8 weeks of their last dose of this IMiD. Pts who have previously received POM treatment were ineligible. In the phase 1 portion, POM was administered at 2, 3 or 4 mg daily in three cohorts on days 1-21 of a 28-day cycle and DEX (40 mg) and PLD (5 mg/m2) were fixed and given intravenously on days 1, 4, 8, and 11. Results As of June 20th, 2014, 48 pts were enrolled in the trial and a total of 47 pts had received study drug. Pts had received a median of 4 prior treatments (range 1-18), with a median of 2 prior IMiD-containing regimens (range, 0-8). Fifty-three percent of the pts had received a prior PLD-containing regimen and 21% had received a prior IMiD and PLD combination treatment. Among all enrolled pts, 40 pts discontinued treatment and seven remain active. Pts completed a median of 3 cycles (range: 1-8), with a median follow-up time of 5.4 months (range: 0-22). During the phase 1 portion of the trial, the maximum tolerated dose (MTD) of POM was established at 4 mg. Enrollment of pts into the phase 2 portion of the trial began at the MTD. However, neutropenia ≥ grade 3 was observed at this dose in 10/17 (58.8%) phase 2 pts; and, as a result, the protocol was amended so that the MTD was lowered to 3 mg for all pts subsequently enrolled. Among the 36 pts enrolled in phase 2, 78% percent were refractory to LEN and steroids with or without other agents and 47% had previously received PLD. A median of 2 cycles (range, 1 to 8) were administered among the pts enrolled in phase 2. Thirty-five pts were evaluable for response as one pt was active but had not yet had any post-baseline disease assessments. Among all pts enrolled in phase 2, the overall response rate (ORR) and clinical benefit rate (CBR) were 29% and 49%, respectively, with 6 pts (17%) showing stable disease and 12 pts (34%) demonstrating progressive disease. For all pts enrolled in phase 2, the median follow-up time was 4.7 months (range 0-12) and the median PFS was 5.3 months. ORR and CBR for pts in the phase 2 were higher among pts receiving POM at 3 mg (32% and 58%, respectively) than among pts receiving POM at 4 mg (25% and 37%, respectively). Pts receiving the 4 mg dose of POM experienced more toxicities resulting in discontinuations, which likely explains the lower ORR and CBR observed among pts receiving this POM dose. Common ≥ grade 3 adverse events observed throughout the trial were neutropenia (21 pts; 44.7%), lymphopenia (10 pts; 21.3%), and hyponatremia (4 pts; 8.5%). One pt died of grade 5 sepsis. Conclusions This phase 1/2 trial is the first evaluating POM with PLD and DEX and demonstrates that the combination of POM at 3 mg, PLD and DEX using a modified 28-day cycle schedule is safe and effective for the treatment of MM pts refractory to LEN.

Background Pomalidomide is an immunomodulatory drug that has been approved for the treatment of relapse refractory myeloma. A previous small randomized phase 2 study in the United States showed that combination of Pomalidomide, cyclophosphamide and dexamethasone induce a greater response rate than pomalidomide and dexamethasone1. In our prior study, AMN0012, we should that in patients with sub-optimal response to pomalidomide and dexamethasone, the addition of cyclophosphamide can increase response resulting in improvement of progression free survival. In the current study, we seek to randomize Asian patients with RRMM between PCD and PD to confirm the benefit of PCD. Method We conducted a prospective randomized trial of pomalidomide (4mg daily for 21 days followed by 7 days rest) plus dexamethasone 40mg once weekly for 4 weeks with or without cyclophosphamide (400mg once a week) in patients with relapse and refractory myeloma that has to be refractory to lenalidomide and has prior exposure to proteasome inhibitors. Each cycle is 4 weeks. Patients from Singapore, Japan and Korea (NCT03143049) were included in this Asian Myeloma Network trial. The trial was started in Sep 2017 and is still ongoing. To date, 53 patients have been recruited so far. This interim report presents data available up till the data cut-off date of 24 June 2020. Results Forty-six patients have available base line information and safety data and is included in this interim analysis. 50% of patients are male and median age of the cohort is 68 years old. 39% and 28% of patients are International Stage System (ISS) stage 2 and 3 respectively. 20% of patients have abnormal creatinine clearance. Median prior line of treatment is 3. All patients are refractory to lenalidomide and 96% have prior exposure to bortezomib. In addition, 12 patients (26%) and 5 (11%) have been treated with Carfilzomib and Ixazomib respectively. 15 (33%) patients had prior high dose melphalan and autologous stem cell transplant. 20 (44%) patients required dose reduction of pomalidomide, cyclophosphamide or dexamethasone. 89% of patients experience adverse events (AEs) of any grade. Of the 297 episodes of AEs, 43% are grade 3 or higher, with 50% of these episodes related to the study drugs. 57% of patients experienced serious AEs (SAEs) of any grade. Of the 74 episodes of SAE, 89% are grade 3 or higher, with 49% of these episodes related to the study drugs. Almost all of these events are related to cytopenias and infections. 20 (44%) of the patients develop grade 3 neutropenic fever and 9 (20%) patients have grade 3 or higher pneumonia. Only 1 patient experienced grade 3 peripheral neuropathy, 1 patient develop grade 3 pulmonary embolism, 1 patient developed grade 3 venous thromboembolism, and 1 patient experienced grade 3 renal impairment. At a median follow-up of 10.9 months, 9 of the 46 patients have died, and 21 have progressed. Three patients withdrew due to toxicity. While the overall response of the study population is not part of this interim analysis, we assessed the response of patients from the National University Cancer Institute, Singapore which has the highest number of patients recruited to get an idea of the therapeutic efficacy. Of the 14 patients recruited at NCIS, 1 patient achieved CR, 3 VGPR, 7 PR, producing a response rate of 79%. Conclusion In this interim analysis of a prospective randomized study of pomalidomide and dexamethasone with or without cyclophosphamide in Asian patients, we demonstrated the feasibility and efficacy of this combination. Longer follow-up and final analysis of the study will be needed to ascertain the therapeutic advantage of PCD over PD in relapse and refractory myeloma that is refractory to lenalidomide.

Abstract Background: We previously reported substantial activity with single-agent bortezomib (VELCADE®; Vc) in patients (pts) with relapsed or refractory MCL in the PINNACLE study (JCO2006;24:4867–74), which resulted in approval of Vc for MCL pts following ≥1 prior therapy. All pts have now completed treatment. Here we report updated time-to-event data in all pts, and by response category, with extended follow-up. Methods: 155 pts (median age 65 yrs; 55%/41%/4% with 1/2/≥3 prior therapies; 77% Stage IV MCL; 55% positive bone marrow) received Vc 1.3 mg/m2 on days 1, 4, 8, and 11 of 21-day cycles; of these, 141 were response-evaluable. Response and progression were determined by modified International Workshop Response Criteria using independent radiology review. Results: After a median follow-up of 26.4 mo, 55 pts (35%) remained in follow-up; 93 (60%) had died, 2 (1%) had withdrawn consent, and 5 (3%) were lost to follow-up. Pts received a median of 4 treatment cycles (range 1–21; 8 in responding pts). Median time to first response was 1.3 months. Median duration of response (DOR) was 9.2 mo in all responders and has not been reached in pts achieving CR/CRu. Median time to progression (TTP), time to next therapy (TTNT; first Vc dose to start of next therapy), and overall survival (OS) are shown in the table for all pts and by response. Survival rate at 12-mo was 69% overall and 91% in responding pts. In pts refractory to their last therapy (no response or response with TTP <6 mo; n=58), median DOR was 5.9 mo, median TTP was 3.9 mo, median TTNT was 4.6 mo, and median survival was 17.3 mo. Safety profile was similar to previously reported; most common grade ≥3 AEs were peripheral neuropathy (13%), fatigue (12%), and thrombocytopenia (11%). The most common AE resulting in Vc discontinuation was peripheral neuropathy (10%). Twelve (8%) pts died on-study, including 5 (3%) considered related to Vc. Conclusions: Vc provides durable responses plus prolonged time off-therapy and survival in responding pts, suggesting substantial clinical benefit in relapsed/refractory MCL.

Abstract Abstract 208 Background: Combined chemoimmunotherapy with fludarabine, cyclophosphamide and rituximab (FCR) has excellent clinical activity as frontline therapy for patients (pts) with chronic lymphocytic leukemia (CLL). In a subset of pts who exhibited high-risk features, such as serum beta-2 microglobulin (B2M) ≥4 mg/L; the complete remission (CR) was lower and time to progression (TTP) and overall survival (OS) were shorter; therefore characterizing these pts as high-risk. Alemtuzumab (A) has activity as a single-agent and in combination with F in pts with relapsed/refractory CLL. To improve the CR and OS for pts with high-risk CLL, we added A to the FCR regimen (CFAR) as frontline therapy in a Phase II clinical trial. Methods: All pts who met NCI-WG criteria to initiate therapy, were < 70 years and had a B2M ≥4 mg/L were eligible for the study. Frontline CFAR consisted of C-200 mg/m2 D3-5, F-20mg/m2 D3-5, A-30mg IV D1,3,5, and R-375–500 mg/m2 D2. Courses were repeated every 28 days for a total of 6 courses. All pts received pegylated filgrastim 6mg SC with each course of therapy. All pts received allopurinol for tumor lysis prophylaxis. Antibiotic prophylaxis with TMP/SMX DS and valacyclovir or valganciclovir was also given to all pts. CMV antigenemia was monitored before each course. Results: A total of 60 pts were enrolled from July 2005 through August 2008 (Table). One pt was lost to follow-up. The median age was 59 yrs (range 42–69) and 44 (75%) were male. Median B2M was 5.1 mg/L (4–11.6); HGB was 11.5gm/dL (5.5–15.1); PLT was 139 k/μL(41–446); WBC was 100k/μL (5–665); ALC was 92k/μL (4–619); and 30 pts (51%) were Rai stage III-IV. The median number of courses administered was 4 (2–6); reasons for not completing 6 courses included delayed recovery of counts (18), infection (8), AIHA (4), treatment failure (3) and pt. choice (2). CR was achieved in 70%, nPR in 3%, PR in 18%, and 7% pts did not respond, leading to an ORR of 92% (Table). There was no significant correlation between CR or OR with Rai Stage, IgVH mutation status, FISH status, ZAP70 and CD38 expression. After a median follow-up of 24 months (3–49), 19(32%) pts have progressive disease. Patients with 17p deletion and unmutated IgVH had significantly shorter TTP as shown in the >Table. Eleven (19%) pts have died: 4 with disease progression after achieving CR; 2 who did not respond; 2 with Richter's transformation; 1 transformed into AML; 1 due to metastatic lung cancer; and 1 due to severe pneumonia 8 months after achieving CR. Grade 3/4 neutropenia and thrombocytopenia occurred in 31% and 13% courses. Major infections, including pneumonia and sepsis, were reported for 10(17%) pts. Minor infectious such as bronchitis, urinary tract infections and herpes zoster were reported for 15(25%) pts. In a historic cohort of high-risk pts treated with FCR, grade 3/4 neutropenia and thrombocytopenia occurred in 31% and 10% courses; and major and minor infections were seen in 15% and 23% pts respectively, all comparable to that seen with frontline CFAR. A-associated infusion reactions occurred in 42 (71%) pts. CMV reactivation occurred in 7 (12%) pts, all of whom were on valacyclovir prophylaxis. There was 1 death due to CMV pneumonia; all other episodes of CMV reactivation were promptly treated with valaganciclovir leading to resolution of fever and/or antigenemia. The median OS for all pts has not been reached (49+mo) and the median TTP is 38 months. Conclusion: CFAR is an active frontline regimen in high-risk pts with CLL. Although CR rates in pts with other high-risk features such as 17p deletion and unmutated IgVH were >50%, TTP was significantly shorter for these pts than for pts without these features. With current follow-up, OS, TTP, infectious complications and grade 3/4 hematologic toxicity are comparable to historic high-risk pts treated with FCR.

Abstract Abstract 427 Rituximab is effective as single agent therapy in the treatment of follicular lymphoma (FL), and when combined with chemotherapy has extended remissions and survival. Epratuzumab (Immunomedics), a humanized anti-CD22 monoclonal antibody, also has single agent activity in FL, and in combination with rituximab led to durable complete responses in the treatment of patients (pts) with relapsed and refractory indolent NHL. To evaluate the hypothesis that combining a second biological agent with rituximab might improve efficacy with good tolerability, the CALGB treated 60 previously untreated pts with epratuzumab and rituximab in a multicenter phase II trial and we report here the preliminary response and toxicity findings. Rituximab was administered at 375 mg/m2 iv weekly for four weeks, then every 8 weeks for four additional doses for a total of 8 doses over 9 months. Epratuzumab, was given at 360 mg/m2 two days before the first rituximab dose to assess toxicity. From week 2 on, epratuzumab was given before the rituximab on the same day for a total of 8 doses over 9 months. Fifty-seven evaluable pts were enrolled between May 2008 and September 2009. FLIPI scores at study entry were 13 (22%) low; 28 (47.5%) intermediate; and 18 (30.5%) high. Fifty-three pts completed all therapy through month 9. One pt was taken off therapy due to progression after month 5. One pt died during induction from line sepsis. Two pts were taken off study due to adverse events, 1 during induction (grade 4 thrombosis and MI), 1 following month 5 (dyspnea, hypoxia and pulmonary NOS). All other toxicities were grade 3 or lower, including fatigue (grade 3 3%, grade 2 17%), nodal pain (grade 3 5%, grade 2 8%), and cytokine release and pruritis (grade 2, 5% each). To date, there have been 19 CRs (33.3%), 29 PRs (50.9%)(ORR 84.2%); 9 (15.8%) had stable disease. All 19 CR patients completed all treatment. The mean time to CR was 9 months. Two patients progressed after a period of stable disease, and 25 of the 29 patients who achieved PR remain in response. All 19 CRs also remain in remission at this point with a median follow-up of 0.82 years (range 0.52 to 2.0). FLIPI score was not predictive of response. The CR rate in low risk pts was 31%, 44% in intermediate risk and 18% in high risk pts. There was a trend toward higher CR rate among patients with FcgR2A His (n=10, CR 60%) and to a lower CR rate among those with FcgR2A Arg (n=14, CR 14.3%). Correlations with PET scan at week 3, with tissue biomarkers and to statin use are being analyzed. Rituximab and epratuzumab is an effective and very well tolerated regimen with an ORR of 84% in previously untreated patients with follicular lymphoma.

Abstract Background The highly aggressive plasmablastic lymphoma (PBL), originally described almost exclusively in HIV+ patients, was nearly uniformly fatal in the pre-HAART era. We hypothesized that aggressive chemotherapy and HAART could result in cures. Methods We retrospectively analyzed baseline characteristics, treatment patterns and outcomes of patients (pts) with PBL treated at multiple centers within the AIDS Malignancy Consortium (AMC). HIV positivity was not required. 19 confirmed PBLs from 9 national AMC sites diagnosed between 1999 and 2008 were evaluated. Results 17/19 patients (pts) with confirmed PBL were HIV+. Data was captured at initial diagnosis on 12 pts (all HIV+) and 7 with relapsed/refractory disease (5 HIV+). HAART status at PBL initial diagnosis was 33% on, 58% off, and unknown 8%. Median CD4 count 110 (range 4-658). First line chemotherapy was given to 10/12 (83%) newly diagnosed patients with stage I/II (6) vs III/IV(6) disease. This was CHOP(4), CDE (1), EPOCH (2) and EPOCH with high dose methotrexate and zidovudine (2). Second line therapy was given to 5/7 relapsed/refractory patients with stage I (1) vs Stage III/IV (5) disease and a median CD4 83 (range 10-202): EPOCH alternate HD Mtx+AZT (n=1); Hyper-CVAD (n=2); High dose Mtx + AZT (n=1); VACOP-B(n=1). One pt underwent BEAM based autologous stem cell transplant. For both groups combined, 6 patients experienced grade 3/4 toxicity. Febrile neutropenia was the most common grade 3/4 toxicity (4 patients) followed by thrombocytopenia (3 patients). One patient with refractory disease experienced grade 5 toxicity. For the 12 newly diagnosed patients, 8 patients were alive at last follow-up and 4 had died. Median follow-up for survivors was 73 (range, 40-165) weeks. One-year survival was 66.7% (SE, 13.6). See Figure 1. For the 7 relapsed/refractory patients, 2 patients were alive at 24 and 54 weeks, and 1 was lost to follow-up. One-year survival was 53.6% (SE, 20.1%). Conclusions In the HAART era, aggressive treatment of PBL can result in significant survival times. However, determination of the superior treatment regimen could not be determined from this small patient sample. CTSU 9177 is prospectively studying PBL with EPOCH.
