4559 Background: GC has a high overall response rate (ORR) but a high relapse rate in pts with untreated mUC. Inhibition of programmed death-ligand 1 (PD-L1) with A can lead to long-term survival, but single-agent ORR is modest. We report the outcomes of GC+A in a cohort pts with mUC. Methods: This study was designed to assess the safety of GC + A in 10 pts with untreated mUC prior to testing GC + A in a neoadjuvant study in pts with muscle-invasive disease. The primary endpoint was safety as assessed by a predefined dose limiting toxicity (DLT) rate during the first cycle in the first 6 pts. Total accrual goal was 10 pts to collect preliminary data on ORR and progression-free survival (PFS). RECIST 1.1 assessments were performed every 9 wks. Pts received 6 cycles of GC + A induction and then A maintenance every 3 wks. Results: No DLTs occurred during the first cycle in the first 6 pts. Grades 3-4 neutropenia and anemia occurred in 6/10 and 7/10 pts, respectively. Three pts required gemcitabine dose reductions for hematologic toxicity and 2 pts had febrile neutropenia. One pt discontinued cisplatin after 2 cycles for grade 3 hearing impairment but completed induction with gemcitabine and A. Only 1 pt discontinued study therapy due to treatment-related adverse events (AEs), including A-related grade 4 encephalopathy and grade 3 polyneuropathy. Three of 10 pts had visceral (liver or bone) metastases. Of the 10 pts, 1 pt is completing induction but meets initial criteria for partial response (PR), 8 pts had confirmed PR, and 1 pt had progressive disease (PD). Of 9 pts with confirmatory scans, the median PFS was 10.6 months (95% CI 6.7, N/A). Of 8 pts with confirmed PR, 5 eventually had PD, 1 has just completed induction, 1 remains without PD at 25 months, and 1 had consolidation surgery with a pathologic complete response and remains disease-free at 21 months. Conclusions: This 10 pt study met its primary safety endpoint. The neoadjuvant study is ongoing (NCT02989584). Although there were a substantial number of grade 3-4 toxicities, therapy was discontinued due to treatment-related AEs in only 1 pt. Immune correlative studies are ongoing. Clinical trial information: NCT02989584.

PurposeNovel approaches are needed for patients with metastatic urothelial cancer (UC). This trial assessed the efficacy and toxicity of bevacizumab in combination with cisplatin and gemcitabine (CGB) as first-line treatment for patients with metastatic UC.Patients and MethodsChemotherapy-naive patients with metastatic or unresectable UC received cisplatin 70 mg/m2on day 1, gemcitabine 1,000 to 1,250 mg/m2on days 1 and 8, and bevacizumab 15 mg/kg on day 1, every 21 days.ResultsForty-three patients with performance status of 0 (n = 26) or 1 (n = 17) and median age of 66 years were evaluable for toxicity and response. Grade 3 to 4 hematologic toxicity included neutropenia (35%), thrombocytopenia (12%), anemia (12%), and neutropenic fever (2%). Grade 3 to 5 nonhematologic toxicity included deep vein thrombosis/pulmonary embolism (21%), hemorrhage (7%), cardiac (7%), hypertension (5%), and proteinuria (2%). Three treatment-related deaths (CNS hemorrhage, sudden cardiac death, and aortic dissection) were observed. Best response by Response Evaluation Criteria in Solid Tumors was complete response in eight patients (19%) and partial response in 23 patients (53%), for an overall response rate of 72%. Stable disease lasting ≥ 12 weeks occurred in four patients (9%), and progressive disease occurred in six patients (14%). With a median follow-up of 27.2 months (range, 3.5 to 40.9 months), median progression-free survival (PFS) was 8.2 months (95% CI, 6.8 to 10.3 months) with a median overall survival (OS) time of 19.1 months (95% CI, 12.4 to 22.7 months). The study-defined goal of 50% improvement in PFS was not met.ConclusionCGB demonstrates promising OS and antiangiogenic treatment-related toxicities in the phase II setting of metastatic UC. The full risk/benefit profile of CGB in patients with metastatic UC will be determined by an ongoing phase III intergroup trial.

Purpose The benefit of salvage chemotherapy is modest in metastatic urothelial cancer. We conducted a randomized, noncomparative phase II study to measure the efficacy of cetuximab with or without paclitaxel in patients with previously treated urothelial cancer. Patients and Methods Patients with metastatic urothelial cancer who received one line of chemotherapy in the perioperative or metastatic setting were randomly assigned to 4-week cycles of cetuximab 250 mg/m2 with or without paclitaxel 80 mg/m2 per week. We used early progression as an indicator of futility. Either arm would close if seven of the initial 15 patients in that arm progressed at the first disease evaluation at 8 weeks. Results We enrolled 39 evaluable patients. The single-agent cetuximab arm closed after nine of the first 11 patients progressed by 8 weeks. The combination arm completed the full accrual of 28 patients, of whom 22 patients (78.5%) had visceral disease. Twelve of 28 patients had progression-free survival greater than 16 weeks. The overall response rate was 25% (95% CI, 11% to 45%; three complete responses and four partial responses). The median progression-free survival was 16.4 weeks (95% CI, 12 to 25.1 weeks), and the median overall survival was 42 weeks (95% CI, 30.4 to 78 weeks). Treatment-related grade 3 and 4 adverse events that occurred in at least two patients were rash (six cases), fatigue (five cases), and low magnesium (three cases). Conclusion Although it had limited activity as a single agent, cetuximab appears to augment the antitumor activity of paclitaxel in previously treated urothelial cancers. The cetuximab and paclitaxel combination merits additional study to establish its role in the treatment of urothelial cancers.

10622 Background: NSABP B-18 randomized women with operable breast cancer to receive chemotherapy either pre- or postoperatively; OS and DSF rates at 9 years were identical. Importantly, pathologic complete response (pCR) was directly proportional to DFS and OS. Recently, dose dense adjuvant chemotherapy has shown a statistically significant improvement in DFS and OS. However, no data is available for the use of dose dense preoperative chemotherapy at this time. Methods: Women enrolled in the I-SPY correlative trial with newly diagnosed breast cancer, T ≥ 3cm, any N, M0 were evaluated to assess response rates and safety to dose dense neoadjuvant chemotherapy (doxorubicin 60 mg/m2 IV Q2 wks × 4, paclitaxel 175 mg/m2 IV Q2 wks × 4, and cyclophosphamide 600 mg/m2 IV Q2 wks × 4). Results: Since 02/2003, 43 pts have been treated with dose dense neoadjuvant chemotherapy on the I-SPY trial at UAB (mean age 47.9). 47% of the pts were ER+, 37% were PR+ and 5% were Her2+ by FISH. 2 pts dropped out for personal reasons and 9 pts are actively undergoing treatment. Overall, 32 pts received dose dense chemotherapy and proceeded to surgery. Of those, 31 received dose dense sequential ATC and 1 received dose dense concurrent AC followed by T. 34% had a pCR (breast & nodes) while an additional 10% had a pCR in the breast but residual disease in lymph nodes; 41% had a PR; 9% had SD; and 6% had PD. Hematologic toxicity consisted of grade 3 anemia in 2 pts, febrile neutropenia in 2 pts and no grade 4 thrombocytopenia. Non-hematologic grade 3–4 toxicity consisted of mediport-associated thrombosis in 2 pts, hyperglycemia in 2 pts, syncope in 1 pt, neuropathy in 1 pt, and disseminated varicella in 1 pt. Conclusion: Our results show that dose dense neoadjuvant chemotherapy achieves a pCR (breast & nodes) in about 1/3 of patients (34%) with tolerable toxicity. No significant financial relationships to disclose.

e15144 Background: There is strong interest in the development of novel agents to further improve the therapeutic ratio of neoadjuvant chemoradiotherapy for rectal cancer. CRLX101 is an investigational nanoparticle-drug conjugate with a camptothecin payload. The purpose of this Phase Ib/II study is to assess toxicity and to evaluate whether the addition of CRLX101 to chemoradiotherapy can improve pathologic complete response (pCR) for rectal cancer. Methods: This is a single-arm multicenter Phase Ib/II study examining the addition of CRLX101 to a standard capecitabine-based chemoradiotherapy regimen. Phase Ib employs a 3+3 dose escalation design with starting dose of 12 mg/m2 every other week (QOW). Dose level +1 was 15 mg/m2 (MTD for CRLX101 single agent QOW). Upon reaching MTD for QOW dosing, protocol was modified to evaluate QW CRLX101 dosing starting at 12 mg/m2 and 15 mg/m2as +1 level. Secondary endpoints included pCR and clinical outcome. Results: A total of 32 patients were enrolled on the trial. 26/32 had T3-4, 9/32 had N2 and 16/32 had N1 disease. For QOW dosing, 9 patients completed treatment without DLT and MTD was identified as 15 mg/m2 QOW. 14 patients were treated on the Phase II portion of the study at 15 mg/m2 QOW prior to the initiation of weekly dosing Phase Ib cohorts. For QW dosing, 0/3 patients experienced DLT at 12 mg/m2 and 1/6 patients experienced DLT at 15 mg/m2. The DLT was skin desquamation requiring treatment delay. QW MTD was identified as 15 mg/m2. Toxicities (all grade 3 except lymphopenia) that could possibly be attributed to CRLX101 are in Table 1. Full clinical and pathologic staging were available for 29/32 patients. Mean neoadjuvant rectal (NAR) score was 19 with standard deviation of 15. At the weekly MTD, 3/6 patients had pCR. Conclusions: CRLX101 weekly at 15 mg/m2+ standard capecitabine-based chemoradiotherapy appears to be well tolerated, with promising pCR rates that warrants further evaluation. A larger PhII trial should be considered with this regimen. Clinical trial information: NCT02010567. [Table: see text]

41 Background: Sorafenib is a tyrosine kinase inhibitor targeting VEGFr, PDGFr, Raf and other pathways. Encouraging response and survival were observed in a phase II trial combining sorafenib with chemotherapy in GE cancer (J Clin Oncol 27:2947;2010). We are studying single agent sorafenib in a phase II trial with the primary endpoint to assess progression free survival (PFS). Secondary endpoints include response and therapy tolerance. Methods: Patients (pts) with measurable metastatic E and GEJ cancer with no more than 3 prior chemotherapy regimens were treated with sorafenib 400 mg BID. CT scans were performed monthly for the first 2 months, then every 2 months. Results: Sixteen of 35 pts have been accrued and 14 are currently evaluable. 13 male, 3 female, median KPS 80%, age 58, GEJ 7, E 9, squamous 2, adenocarcinoma (AC)14. An ongoing complete response (11+ months) was observed in a pt with biopsy proven metastatic neck lymphadenopathy (E primary AC, recurrence after prior chemoradiotherapy and surgery). A second pt (GEJ AC) had protracted stable disease in bulky celiac node disease (15+ months). Grade 3 toxicity was limited to skin rash (1 pt), hand foot reaction (1 pt), and fatigue (1 pt). Only 3 of 14 pts (21%) had early disease progression at 2 months or less. Median PFS 4 mos, 4 patients (29%) continue on therapy for more than 7 months. The majority of tumors tested positive for phospho-erk by immunohistochemistry (11/14, 79%). Conclusions: The observation of a durable complete response and protracted stable disease to sorafenib in E cancer is remarkable. Further accrual continues to define PFS.

4526 Background: Standard methotrexate, vinblastine, doxorubicin and cisplatin (MVAC) demonstrates a survival benefit in the neoadjuvant setting for patients (pts) with muscle invasive bladder cancer (MIBC). Compared with standard MVAC, AMVAC yielded higher response rates with less toxicity in the metastatic setting. Methods: Pts with MIBC, cT2-T4a, and N0-N1 with CrCl >=50 and adequate hepatic and marrow function were eligible. Pts received 3 cycles of AMVAC (methotrexate 30 mg/m2, vinblastine 3 mg/m2, doxorubicin 30 mg/m2, cisplatin 70mg/m2) on day 1, with pegfilgrastim 6 mg day 2 or 3, every 2 weeks. Pts with CrCl < 60 could receive cisplatin split over 2 days. Radical cystectomy (RC) with lymph node dissection was performed 4-8 weeks after the last dose of chemotherapy. Primary endpoint was pathologic complete response (pCR) rate. Results: Accrual is complete with 44 MIBC pts enrolled at 2 institutions (FCCC, TJU) over a 25 month period. Median age 64 (range 45-83). Three withdrew from study early and are not evaluable for response (2 physician discretion, 1 withdrawal of consent). An additional 8 are currently receiving treatment on study with toxicity and response data pending. Of the 33 evaluable pts for whom final data is available, 30 received all 3 cycles of AMVAC at full dose. Three pts received < 3 cycles due to grade 3 fatigue (1), low platelets (1), and disease progression precluding RC (1). 32/33 pts underwent RC, all within 8 weeks of last chemotherapy. Median time from start of chemotherapy to RC was 9.7 wks (range 4.6-13 wks). 13/33 pts (39.4%, 95% CI, 22.7-56.1%) had a pCR. An additional 3 (9.1%) were downstaged to non muscle invasive disease. For the intent to treat cohort (n=36) 8 pts had grade 3-4 AMVAC related adverse events, the most common being anemia (3), fatigue (3) and neutropenia (2) and overall pCR rate was 36.1%. (95% CI, 20.4-51.8%). All pts will have completed study treatment by April 2012. Final results will be presented. Conclusions: Neoadjuvant AMVAC is well tolerated and preliminary results show a pCR rate similar to that reported for standard 12-week MVAC, suggesting that AMVAC for three cycles (6 weeks) is a safe and efficient alternative.

373 Background: There is no standard chemotherapy regimen for PC patients who have progressed on G and fluoropyrimidine-based therapy. Single agent nab-P had limited activity on a second-line phase II trial in PC. Synergistic preclinical studies with G and taxanes have been reported. Nab-P targets stromal cells and leads to improved delivery of chemotherapy to PC cells. The combination of G + nab-P might be an effective approach in pretreated PC. Methods: A retrospective analysis of advanced refractory PC patients treated from Sep 2010 to Aug 2011 with the combination of G + nab-P was performed at the Sylvester Comprehensive Cancer Center. Patients received G 1000mg/m2 and nab-P 100mg/m2 on D1, 8 and 15 of a 28 day cycle. Treatment response was assessed by review of imaging studies using the RECIST criteria, CA19-9 response and symptomatic improvement. The progression-free survival (PFS) and overall survival (OS) were calculated from time of commencement of G + nab-P until documented progression or death respectively. Results: 10 patients were treated with G + nab-P; 60%, 30% and 10% of patients had received 3, 2 and 1 prior chemotherapy regimen. 90% and 80% received prior G or fluoropyrimidine-based regimen respectively. Therapy was discontinued in one patient following only one dose of G + nab-P (Cycle 1, day 1) due to grade 2 thrombocytopenia. The remaining 9 patients received a median of 4 cycles. Two (22.2%) patients had confirmed PR, 3(33.3%) patients had confirmed stable disease while 4 (44.4%) patients progressed on therapy. The median PFS was 13.7 weeks. The median PFS was 20 weeks in patients with PR or SD and 9.9 weeks in patients with PD. Recurrent malignant ascitis resolved in a patient with peritoneal carcinomatosis. Treatment was well tolerated; grade 3-4 hematologic toxicity included anemia, thrombocytopenia and neutropenia in 2, 1 and 2 patients respectively. 70% of patients required G-CSF support. Non hematologic Grade 3-4 toxicities included fatigue, peripheral neuropathy; nausea and vomiting in 3, 2 and 1 patient respectively. Conclusions: G + nab-P resulted in clinical benefit in half of this group of advanced PC patients who had previously progressed on G and fluoropyrimidine-based regimens.

503 Background: Dual trastuzumab plus pertuzumab (HP) has shown promising pathologic complete response (pCR) rates in HER2[+] EBC although lower to CT regimens. Identification of new markers of sensitivity to HP could help to de-escalate CT. PHERGain assessed early metabolic response by F-PET to neoadjuvant HP and the opportunity of CT de-escalation with a response-adapted strategy in patients (pts) with HER2[+] EBC. Methods: PHERGain randomized (1:4 ratio) centrally-confirmed HER2[+] stage I-III EBC pts to receive either docetaxel (T), carboplatin (C), and HP (cohort A) or HP ± endocrine therapy (ET) (cohort B). Randomization was stratified by hormone receptor (HR) status. Pts with subclinical metastases by F-PET were included in a different cohort (cohort C). Centrally-reviewed F-PET was performed prior to randomization and after 2 cycles of TX (cohorts A/B). Cohort A pts completed a total of 6 cycles regardless of F-PET results. Cohort B/PET-responder (RX) pts continued with HP ± ET for 6 cycles, while PET-non-RX pts were switched to receive 6 cycles of TCHP. After surgery, cohort B/PET-RX pts who did not achieve a pCR received 6 cycles of TCHP and all pts from cohorts A/B completed 18 cycles of HP. Cohort C pts received 6 cycles of TCHP. Co-primary endpoints were breast/axilla pCR rate (ypT0/isN0) among cohort B/PET-RX pts and 3-year invasive disease-free survival (iDFS) in pts allocated to cohort B. Results: A total of 376 pts were included (71 pts in cohort A, 285 pts in cohort B, and 20 pts in cohort C). In cohort B, median age was 50 years, 49.2% had node-positive disease, and 67.4% had HR+ tumors. pCR in cohort A was achieved in 41 pts (57.7%, 95% CI 47.4-69.4%) and it was observed in 101 pts included in cohort B (35.4%, 95% CI 29.9-41.3%). Among cohort B pts, 227 (79.6%) were PET-RX; 86 of them (37.9%, 95% CI 31.6-44.5%) obtained a pCR. Among PET-non-RX pts, 15 (25.9%, 95% CI 15.3-39%) achieved a pCR after adding CT (TCHP). PET-RX pCR by HR status was 44.3% for HR[-] and 35% for HR[+] (p = 0.184). The incidence of commonly reported adverse events (AEs) was higher in pts allocated to cohort A (grade≥3 AEs 58.8 vs 12%; serious AEs 29.4 vs 4.6%). The rate of pts with a ≥10% global health status decline in cohorts A and B were 40.8 and 23.5%, respectively. Conclusions: F-PET identify pts with HER2[+] EBC who are more likely to benefit from CT-free dual HER2-blockade with HP. Follow-up is ongoing for iDFS endpoint. Depending on the results of this second co-primary endpoint, this strategy could select a group of HER2[+] EBC pts who would not need CT. Clinical trial information: NCT03161353 .

Abstract Abstract 210 Background: Alemtuzumab (Campath-1H) is approved for the treatment of CLL. CALGB sought to determine whether alemtuzumab can improve the CR rate and eradicate MRD after induction chemoimmunotherapy by performing a phase II study administering FR followed by alemtuzumab consolidation to previously untreated, symptomatic CLL patients (pts). We previously reported preliminary toxicity data (Lin et al. ASH 2007) and now report final toxicity and response data. Methods: Pts received fludarabine 25 mg/m2 IV on days 1–5, and rituximab 50 mg/m2 IV on day 1, 325 mg/m2 on day 3, and 375 mg/m2 on day 5 of cycle 1 and then only on day 1 of cycles 2–6, repeated every 28 days for up to 6 cycles. Four months after the last fludarabine dose, pts with stable (SD) or responsive disease by NCI 96 criteria received SC alemtuzumab 3 mg on day 1, 10 mg on day 3, and 30 mg on day 5, and then thrice weekly thereafter for 6 weeks (18 total doses). Pts received standard Pneumocystis (PCP) and Varicella zoster virus prophylaxis and were monitored weekly by PCR for Cytomegalovirus (CMV) viremia. When unacceptable serious infectious toxicity was noted in pts who received alemtuzumab after achieving CR from FR induction, the study was amended so that only PR or SD pts received alemtuzumab after FR. Results: Median age of pts (n=102) was 61 years (range, 23–82), 74% were male, and 30% were Rai stage III/IV. FR was well tolerated; 93% of pts received at least 3 cycles, and 77% completed all 6 cycles. Overall, complete and partial response (OR, CR, PR) rates after FR induction were 90%, 29% and 61%, and 15% were MRD negative by flow cytometry. Fifty-eight pts received alemtuzumab, and 42 (72%) completed the planned 6 weeks of therapy. OR, CR, and PR rates after alemtuzumab (n=58) were 91%, 66% and 26%, and 50% were MRD negative. Twenty-eight of 45 pts (62%) in PR after FR who received alemtuzumab attained CR. Of 11 pts in CR after FR who received alemtuzumab, 5 were MRD negative prior to consolidation and 3 of the other 6 converted to MRD negative afterwards. By intent-to-treat for all patients enrolled, OR, CR, and MRD negativity were attained by 90%, 57% and 42% of pts. With a median follow up of 34 months, median progression free survival (PFS) was 37 months (95% CI, 33–43 months); PFS was 73% and overall survival (OS) 86% at 2 years. Two-year PFS (76% vs 70%, p=0.54) and OS (84% vs 88%, p=0.89) were similar for pts who did and did not receive alemtuzumab. Similarly, there were no differences in PFS or OS among the 30 pts in CR after FR whether or not they received alemtuzumab, although the numbers were small. Grade 3–4 neutropenia and thrombocytopenia were observed in 43% and 19% of pts during alemtuzumab therapy. Grade 3–4 non-hematologic toxicity was observed in 41% of pts, including 19% infections and 19% febrile neutropenia, during alemtuzumab therapy. As we previously reported, 5 pts in CR after FR who received alemtuzumab died from infections (viral meningitis, Listeria meningitis, Legionella pneumonia, CMV and PCP pneumonia), and one pt in PR after FR who received alemtuzumab died of Epstein-Barr (EBV) viremia without evidence of EBV lymphoma. These grade 5 toxicities occurred both during and for up to 7 months after alemtuzumab therapy. Conclusions: Alemtuzumab consolidation improved the CR and MRD negative rates after FR induction. However, alemtuzumab consolidation resulted in significant toxicity, particularly severe infections in pts who achieved a CR after FR induction. Longer follow up is needed to determine if the improved CR and MRD negative rates following alemtuzumab consolidation will eventually result in improved PFS or OS, especially among pts who achieved a PR after FR induction.

The Impact

It remains unclear whether immune-related adverse events (irAEs) and glucocorticoid use could impact long-term outcomes in patients treated for solid tumors with immune checkpoint inhibitors (ICI). All patients treated with a single-agent ICI for any advanced cancer were included in this retrospective unicentric study. The objectives were to assess the impact of grade ≥3 irAEs, glucocorticoid use and the interruption of immunotherapy on progression-free survival (PFS) and overall survival (OS). In this 828-patient cohort, the first occurrence of grade ≥3 irAEs had no significant impact on PFS or OS. Glucocorticoid administration for the irAEs was associated with a significantly shorter PFS (adjusted HR 3.0; p = 0.00040) and a trend toward shorter OS. ICI interruption was associated with a significantly shorter PFS (adjusted HR 3.5; p < 0.00043) and shorter OS (HR 4.5; p = 0.0027). Glucocorticoid administration and ICI interruption were correlated. In our population of patients treated with single agent ICI, grade ≥3 irAEs did not impact long-term outcomes. However, the need for glucocorticoids and the interruption of immunotherapy resulted in poorer long-term outcomes. The impact of grade ≥3 irAEs reported in other studies might then be explained by the management of the irAEs.
