About 70% of patients with large B-cell lymphoma (LBCL) treated with axicabtagene ciloleucel (axi-cel) who achieve a partial response (PR) or a stable disease (SD) on day 30 (D30) PET-CT scan progress, but predictive factors of progression are unknown. This a retrospective study of patients with LBCL treated with axi-cel at MD Anderson Cancer Center between 01/2018 and 02/2021. Among 50 patients with D30 PR/SD, 13 (26%) converted to complete response (CR). Among 95 patients with D30 CR, 72 (76%) remained in CR. On univariate analysis, the only day -5 characteristic associated with conversion from D30 PR/SD to subsequent CR was a higher platelet count (p=0.05). The only D30 factor associated with conversion from D30 PR/SD to subsequent CR was lower D30 SUVmax (p<0.001), and all patients with and D30 SUVmax ≥10 progressed. After a median follow-up of 12 months, no significant difference in median progression-free survival was observed when comparing patients who converted from D30 PR/SD to subsequent CR to those who had been in CR since D30 (p=0.19). Novel predictive and prognostic markers based on tissue biopsy and non-invasive diagnostic assays are needed to more effectively identify these patients and characterize the biology of their residual disease.

OBJECT Adenoid cystic carcinoma (ACC) is a locally aggressive tumor of salivary gland origin. Little data exist to guide treatment when this tumor extends to involve the structures of the skull base. METHODS Fifty-one patients with a diagnosis of ACC affecting the skull base were identified from a prospective database at MD Anderson Cancer Center (from 1992 to 2010). RESULTS Median follow-up for study patients was 6.75 years. The 5- and 10-year overall survival (OS) rates were 78% and 50%, respectively. Sixty-six percent of patients had progression of their disease. The 5- and 10-year progression-free survival (PFS) rates were 46.7% and 21.0%, respectively. Gross-total resection was achieved in 75% of patients, with 49% having microscopically negative margins at the time of first operation. On univariate analysis, resections with microscopically negative margins were associated with a significant OS advantage (20.1 ± 3.3 years) compared with resections that left residual disease, even if microscopic (10.3 ± 1.6 years, p = 0.035). In patients who underwent reoperation, the effect persisted, with improved OS in those with negative margins (21.4 ± 0.0 vs 16.7 ± 4.0 years, p = 0.06). The use of adjuvant radiotherapy was associated with an OS advantage (16.2 ± 2.5 vs 5.5 ± 2.2 years, p = 0.03) at initial diagnosis and improved PFS (7.8 ± 1.0 vs 2.1 ± 0.62 years, p = 0.005), whereas repeat irradiation provided no benefit. The use of adjuvant chemotherapy at diagnosis or at recurrence was not associated with any significant advantage. Multivariate analysis revealed margin-negative resection at initial operation and at recurrence retained OS significance, even after controlling for age, radiation therapy, and T stage. CONCLUSIONS ACC of the skull base is best treated with a multidisciplinary approach aimed at maximal, safe resection. Adjuvant radiotherapy should be offered, whereas chemotherapy does not confer benefit.

Chimeric antigen receptor (CAR) T-cell therapy is a rapidly developing method for adoptive immunotherapy of tumours in recent years. CAR T-cell therapies have demonstrated unprecedented efficacy in the treatment of patients with haematological malignancies. A 90% complete response (CR) rate has been reported in patients with advanced relapse or refractory acute lymphoblastic leukaemia, while >50% CR rates have been reported in cases of chronic lymphocytic leukaemia and partial B-cell lymphoma. Despite the high CR rates, a subset of the patients with complete remission still relapse. The mechanism of development of resistance is not clearly understood. Some patients have been reported to demonstrate antigen-positive relapse, whereas others show antigen-negative relapses. Patients who relapse following CAR T-cell therapy, have very poor prognosis and novel approaches to overcome resistance are required urgently. Herein, we have reviewed current literature and research that have investigated the strategies to overcome resistance to CAR T-cell therapy.

e15060 Background: Microsatellite stable (MSI-S) RS mCRC patients (pts) have a worse prognosis relative to left sided tumors for overall survival (OS). The present analysis aims to test the hypothesis that a triplet-regimen is superior compared to doublet-regimens (DR; FOLFOX or FOLFIRI) for OS. Methods: Pts with treatment-naive RS mCRC at MD Anderson Cancer Center between January/2011 to December/2018 were selected. We compared the progression-free survival (PFS) and OS of mCRC pts treated with FOLFOXIRI versus DR. Pts treated with anti-EGFR therapy were excluded. Results: A total of 37 pts were treated with FOLFOXIRI and 111 pts with DR. There were no statistical difference between groups regarding gender, KRAS and BRAF mutations, peritoneal metastasis and bevacizumab use. There were statistical difference in age (median: 46y vs 59y) and metastasectomy rates (14% vs 32%) (p < 0.001). KRAS mutation was found in 65% of the population. Median follow-up was 55.3m. Median PFS was 6.5m vs 11.2m (HR: 1.30 95% CI 0.85 – 1.99) and median OS was 17.0m vs 26.3m (HR: 1.01 95% CI 0.60 – 1.68). By univariate analysis, pts who have undergone metastasectomy had superior PFS (14.9m vs 9.2m; p<0.001) and OS (32.4m vs 22.9m; p=0.003). By multivariate analysis adjusted for age, BRAF mutation, metastasectomy, bevacizumab use and, treatment regimen, only age and metastasectomy had prognostic influence for PFS (p=0.039 and p=0.026, respectively). Conclusions: Despite RS having a poor prognosis for OS, our study does not suggest that RS mCRC pts benefit from intensive treatment. Randomized clinical trials may suggest more individualized therapies.

Abstract Neurotoxicity is a common occurrence and a major form of morbidity in adult patients with relapsed or refractory (R/R) diffuse large B cell lymphoma (DLBCL) patients treated with anti-CD19 directed chimeric antigen receptor (CAR) T-cell therapy. Variables related to the incidence and severity of neurotoxicity have been relatively well delineated, but the association between neurotoxicity and the efficacy of CAR T-cell therapy has not been well studied. We performed a retrospective analysis of the outcomes of DLBCL patients who developed neurotoxicity following anti-CD19 CAR T-cell treatment. The analysis included 26 patients with R/R DLBCL who received commercial anti-CD19 CAR T-cell therapy. All patients received a lymphodepleting chemotherapy regimen consisting of fludarabine and cyclophosphamide. Twenty-five patients received axicabtagene ciloleucel, and 1 received tisagenlecleucel. The overall incidence of neurotoxicity was 88%; 31% developed severe neurotoxicity (Grade III-IV by CTCAE). Higher neurotoxicity was associated with better PFS by both CTCAE (CR 2.4 ± 1.1 vs. PD 1.4 ± 1.3, p = 0.051) and CARTOX-10 (CR 3.78 ± 4.6 vs. PD 7.7 ± 3.8, p = 0.044) grading systems. Higher neurotoxicity continued to show a trend at 6, 9, and 12 months by the CTCAE grading system (CR 2.4 ± 1.0 vs. PD 1.7 ± 1.3, p = 0.085), and no patients had disease recurrence after 6 months. In this limited cohort, neurotoxicity severity was paradoxically positively correlated with progression-free survival with commercial CAR T-cell therapy and may therefore indicate an effective therapeutic response.

6518 Background: P/G status has been suggested to be an important predictor of outcome in pts with LBCL who receive an ASCT. Newer conditioning regimens which include HDR have been shown to improve results (Khouri, JCO, 2005). The influence of HDR on the outcome of pts based on P/G status has not been determined. Methods: A retrospective review of pts with chemo-sensitive, LBCL who received an ASCT on a research protocol at MD Anderson between 1995 and 2005 was performed. Results: A total of 188 pts were identified. Median age was 49 yrs with 108 (57%) male pts. 147 (78%) had de novo LBCL and 41 (22%) had an LBCL of follicular origin (LBCL-F). 83 (39%) pts received HDR with ASCT. At transplantation 95 pts (50%) were in PR, 71 pts (38%) in CRU and 22 pts (12%) in CR. 142 (76%) pts were P/G negative, 37 (20%) pts P/G positive and 9 (4%) pts unknown. The median follow-up was 44 months. Factors that were considered for outcome included: Age, IPI, # of prior chemotherapies, B2-microglobulin, disease status at transplant, HDR and P/G status. On multivariate analysis, P/G status and HDR were the only predictors for progression and PFS. Pts who were P/G negative and those that received HDR had a hazard ratio (HR) of 0.3 (p<0.001) and 0.5 (p=0.02) for progression, respectively. The cumulative incidence (CI) of progression and progression free survival (PFS) at 54 months according to HDR and P/G status are shown in the table below. P/G Status and HDR were also found to be predictive for pts with LBCL- F on univariate analysis, however due to the small numbers in this subset of pts, multivariate analysis could not be performed. Conclusions: These results suggest that pre-transplant P/G positive status increases the risk of progression of LBCL after ASCT. The addition of HDR to the transplant regimen decreases this risk irrespective of P/G status. [Table: see text] No significant financial relationships to disclose.

Abstract Purine nucleoside analogues, cladribine(2-CdA) and fludarabine (FA), especially combined with cyclophosphamide (CY) are potent cytotoxic drugs for the treatment of chronic lymphocytic leukemia (CLL). In this randomized study we aimed to establish whether combination of 2-CdA plus CY (CC) with FA plus (FC) provide similar benefit to previously untreated patients with CLL. The trial was started in January 2004 and the recruitment was ended in May 2007. The study primary endpoints were overall response (OR) and complete response (CR). The secondary endpoints included progression free survival (PFS), overall survival (OS), minimal residual disease negativity (MRD/-/) and treatment related toxicity. Eligible patients were randomly assigned to receive 6 courses of either 2-CdA 0.12 mg/kg/d i.v. + CY 250 mg/m2/d i.v. or FA 25 mg/m2/d i.v. + CY 250 mg/m2/d, both combinations for 3 consecutive days. The treatment response and toxicity were evaluated according to NCI-WG guidelines. MRD was evaluated in patients with CR using four-color flow cytometry assay. There were no significant difference in the rates of OR, CR, MRD negativity, grade 3/4 neutropenia, thrombocytopenia and infections. PFS and OS were also similar in both groups. In conclusion, CC and FC regimens are similarly active and toxic in previously untreated CLL, however trend of longer OS in CC group is observed.

e12099 Background: The purpose of this retrospective case series was to assess pCR rate, progression-free survival and prognostic factors in TNBC. Methods: We reviewed medical records for 33 consecutive female patients with TNBC (41% node+) treated between July 2015 and April 2018 with neoadjuvant paclitaxel 80 mg/m2 IV weekly plus concurrent carboplatin (AUC 4) every 3 weeks for a total of 12 weeks followed by dose-dense doxorubicin 60 mg/m2 plus cyclophosphamide 600 mg/m2 every 2 weeks for a total of 4 cycles. Surgical pathology was studied to determine the presence or absence of residual disease at surgery. Age at treatment, tumor stage, subsequent hospitalizations, and genetic testing were recorded. Patients with residual disease were treated with adjuvant capecitabine 1500 mg PO BID, one week on, one week off, for 6 monthly cycles ± radiation; some patients with a complete pathological response also received postoperative radiation. Results: Among 33 patients, 17 patients had pCR (52%, median age 58 yrs), 10 had a partial response and 6 had no response or progression (median age 63.5). After surgery 24 patients received radiation therapy (XRT). There were 6 hospitalizations, 3 that were treatment related, 2 for neutropenic fever and one for renal failure induced by carboplatin; all 3 resulted in chemotherapy dose reductions; all 3 had pCR. 3 progressions/recurrences were recorded: 2 after treatment and 1 progression during treatment. Two deaths occurred, 1 secondary to progressive disease. Median progression free survival time was 8.5 months (range 0.1 to 24.0 mos). Median time since diagnosis is 16.7 months (range 8.1 to 37.6 mos). There was no significant difference in the median age of patients who had a pCR compared with patients with residual disease. Conclusions: We observed pCR in patients with TNBC treated with a pre-operative carboplatin-containing regimen (superior to historical pCR rates in patients receiving taxanes and anthracyclines only). Although there are insufficient data to demonstrate increased overall survival, we show an improvement in prognosis with a carboplatin-containing regimen for TNBC.

Abstract The prognosis of patients with relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL) is poor. Chimeric antigen receptor (CAR) T-cell therapy has been approved for R/R DLBCL after 2 prior lines of therapy based on data from single-arm phase 2 trials, with complete responses (CRs) in 40% to 60% of patients. However, a direct comparison with other treatments is not available and, moreover, its true efficacy in real-world patients is unknown. In this single center, retrospective, observational study of 215 patients, we compared outcomes in patients treated with CAR T-cell therapy (n = 69) with a historical population treated with alternate therapies (n = 146). Patients treated with CAR T cell vs alternate therapies demonstrated a CR rate of 52% vs 22% (P &lt; .001), median progression-free survival (PFS) of 5.2 vs 2.3 months (P = .01), and median overall survival (OS) of 19.3 vs 6.5 months (P = .006), and this advantage appeared to persist irrespective of the number of lines of prior therapy. After adjusting for unfavorable pretreatment disease characteristics, superior overall response rate in the CAR T cohort remained significant; however, differences in PFS and OS between cohorts did not. In addition, patients who responded to alternate therapies demonstrated prolonged remissions comparable to those who responded to CAR T therapy. We contend that in select clinical scenarios alternate therapies may be as efficacious as CAR T therapy; thus, additional study is warranted, ideally with randomized prospective trials.

Abstract The phase 3 CLARION study compared carfilzomib-melphalan-prednisone (KMP) with bortezomib-melphalan-prednisone (VMP) in transplant-ineligible newly diagnosed multiple myeloma (NDMM) patients. Patients were randomized 1:1 to KMP or VMP for nine 42-day cycles (C). Patients received carfilzomib on days (D) 1, 2, 8, 9, 22, 23, 29, 30 (20 mg/m2: C1D1, C1D2; 36 mg/m2 thereafter) or bortezomib on D1, 4, 8, 11, 22, 25, 29, 32 (1.3 mg/m2; D4, 11, 25, 32 omitted for C5-9). Melphalan (9 mg/m2) and prednisone (60 mg/m2) were administered on D1-4. The primary endpoint was progression-free survival (PFS). Nine hundred fifty-five patients were randomized (intention-to-treat population: KMP, n = 478; VMP, n = 477). Median PFS was 22.3 months with KMP vs 22.1 months with VMP (hazard ratio [HR], 0.906; 95% confidence interval [CI], 0.746-1.101; P = .159). Median overall survival was similar and not reached in either group (HR, 1.08; 95% CI, 0.82-1.43). Overall response rate was 84.3% for KMP and 78.8% for VMP. Complete response rate was 25.9% for KMP and 23.1% for VMP. Minimal residual disease–negative rates were 15.7% (KMP) and 15.5% (VMP). Adverse events (AEs) of interest (any grade) occurring with a ≥5% higher patient incidence in the KMP arm were acute renal failure (13.9% [KMP] vs 6.2% [VMP]) and cardiac failure (10.8% vs 4.3%). Grade ≥3 AE rates were 74.7% (KMP) and 76.2% (VMP). Grade ≥2 peripheral neuropathy was lower for KMP vs VMP (2.5% vs 35.1%). Treatment with KMP in CLARION did not yield a statistically significant difference in PFS vs VMP. This trial was registered at www.clinicaltrials.gov as #NCT01818752.
