A phase II study of cetuximab-based neoadjuvant and adjuvant treatment strategies, with or without surgery, in patients with locally very advanced squamous cell carcinoma of the oral cavity.

e16050 Background: The purpose is to evaluate the efficacy of sequential regimen using cetuximab-based doublet neoadjuvant chemotherapy, followed by surgery, if tumors resectable, and adjuvant cetuximab-based chemoradiotherapy in locally very advanced OSCC patients. Methods: Patients with T4a/b or N2b/c or N3 OSCC were enrolled to determine the response rate of cetuximab, cisplatin, and 5-FU neo-adjuvant chemotherapy. Cetuximab (400 mg/m2 loading, followed by 250 mg/m2 weekly x 6 weeks) was combined with 2 3-weekly cycles of cisplatin (100 mg/m2) and 5-FU (1000 mg/m2 x 3 days) as neo-adjuvant. Patients whose tumors became operable after neoadjuvant underwent radical surgery followed by adjuvant weekly cetuximab (250 mg/m2), cisplatin (30 mg/m2) and XRT (up to 70 Gy). Patients whose tumors remained inoperable after neoadjuvant received weekly cetuximab (250 mg/m2), cisplatin (30 mg/m2) and XRT (up to 70 Gy). Results: 33 patients were enrolled from Dec. 2009 to Jan. 2011. Average age was 47.3 years. 51.5% had primary lesion in buccal mucosa and 21.2% on tongue. 66.7% and 27.2% had T4b or T4a disease respectively, while 72.7% had N2b/N2c/N3 disease. 28/33 completed treatment course. On ITT analysis, 39.4% (13/33) had partial response and 48.5% (16/33) had stable disease after neoadjuvant. 42.4% (14/33) underwent radical surgery after neoadjuvant, while another 9% (3/33) underwent surgery after bio-chemoradiation. The 1 year disease free survival (resected group), progression free survival (ITT group), and overall survival (ITT group) were 48.8%, 73.2%, and 51.7% respectively. The most common grade 3/ 4 adverse event in neo-adjuvant phase was vomiting (16.1%), while mucositis (75%) and dermatitis (42.8%) accounted for major grade 3/ 4 adverse events during bio-chemoradiation. Conclusions: Cetuximab based sequential regimen was efficacious and well tolerated in improving treatment outcomes in locally very advanced OSCC patients with manageable side effects.

Introduction: Patients with advanced pancreatic cancer have a poor prognosis. FOLFIRINOX (FFX) and gemcitabine plus nab-paclitaxel (GnP) have been established as first-line treatment, but they have not been confirmed as second-line treatment after FFX. The aim of this study was to evaluate the safety and efficacy of GnP as second-line therapy after FFX in patients with unresectable pancreatic cancer. Methods: Twenty-five patients with unresectable pancreatic cancer were enrolled. The patients were treated with GnP after FFX between September 2015 and September 2019. Tumor response, progression-free survival (PFS), overall survival (OS), and incidence of adverse events were evaluated. Results: The response rate, disease control rate, median PFS, and median OS were 12%, 96%, 5.3 months, and 15.6 months, respectively. The common grade 3 or 4 adverse events were neutropenia (76%) and anemia (16%). Conclusions: GnP after FOLFIRINOX is expected to be one of the second-line recommendations for patients with unresectable pancreatic cancer.

The Impact

In the RECOURSE trial which lead to its accreditation, Lonsurf (trifluridine/tipiracil) was shown to extend progression free survival (PFS) by 1.8 months in metastatic colorectal cancer. This Trust audit aims to assess the average quantity of cycles of Lonsurf received by participants and the length of time it extends PFS. Similarly, to identify how many participants required a dose-reduction or experienced toxicities which necessitated supportive therapies. Quantitative data was collected retrospectively from all participants who had received ≥1 cycle of Lonsurf from The Clatterbridge Cancer Centre (CCC) from 2016 until June 2020. Participant electronic patient records were accessed to identify toxicity grading, length of treatment received, the date progression was identified, if dose reductions were applied and if supportive therapies were administered. Lonsurf extends PFS in patients with metastatic colorectal cancer at CCC by 3.0 months (95% CI: 2.73–3.27) and average treatment length was 2.4 months. However, 78 participants (41.5%) received a dose reduction due to toxicities. A total of 955 toxicities were recorded by participants; the most commonly reported toxicities irrespective of grade were fatigue (33.8%), diarrhoea (13.8%) and nausea (12.3%). The most common grade ≥3 toxicities were constipation and infection. The most frequently utilised supportive therapies were loperamide (49.6%) and domperidone (49.1%). Granulocyte colony stimulating factor (GCSF) was required by patients on 5 occasions (0.3%) in total. Lonsurf extends median PFS in patients with metastatic colorectal cancer by 3.0 months. The most common grade ≥3 toxicities which necessitated supportive therapies or a dose reduction were gastrointestinal and infection.

Abstract Lenalidomide plus dexamethasone is effective for the treatment of relapsed and refractory multiple myeloma (MM); however, toxicities from dexamethasone can be dose limiting. We evaluated the efficacy and safety of lenalidomide monotherapy in patients with relapsed and refractory MM. Patients (N = 222) received lenalidomide 30 mg/day once daily (days 1-21 every 28 days) until disease progression or intolerance. Response, progression-free survival (PFS), overall survival (OS), time to progression (TTP), and safety were assessed. Overall, 67% of patients had received 3 or more prior treatment regimens. Partial response or better was reported in 26% of patients, with minimal response 18%. There was no difference between patients who had received 2 or fewer versus 3 or more prior treatment regimens (45% vs 44%, respectively). Median values for TTP, PFS, and OS were 5.2, 4.9, and 23.2 months, respectively. The most common grade 3 or 4 adverse events were neutropenia (60%), thrombocytopenia (39%), and anemia (20%), which proved manageable with dose reduction. Grade 3 or 4 febrile neutropenia occurred in 4% of patients. Lenalidomide monotherapy is active in relapsed and refractory MM with acceptable toxicities. These data support treatment with single-agent lenalidomide, as well as its use in steroid-sparing combination approaches. The study is registered at http://www.clinicaltrials.gov as NCT00065351.

11529 Background: Nab-paclitaxel (albumin-bound paclitaxel) has shown preclinical activity against pediatric solid tumors. Preclinical data in EwS PDX models suggested high activity of nab-paclitaxel in tumors expressing high-levels of SPARC. Tumoral SPARC facilitates the accumulation of albumin in the tumor and increases the effectiveness of albumin-bound paclitaxel. Nab-paclitaxel utilizes albumin to deliver paclitaxel via caveolin-mediated endocytosis which is expressed in the EwS cells surface. We hypothesized that SPARC can be a predictive biomarker for nab-paclitaxel in EwS and DSRCT that could potentially be relevant for a better design of clinical trials and personalized treatments using nab-paclitaxel. Methods: Main endpoint of GEIS-39 was the overall response rate (ORR) assessed by RECIST 1.1 criteria with centralized pathology and imaging review. Secondary objectives included safety according to the CTCAE 4.0 criteria. Patients aged ≥ 6 months and ≤ 40 years, with relapsed/refractory DSRCT were eligible after having received at least one previous poly-chemotherapy line; EwS must have received at least two standard chemotherapy lines. Prior taxane therapy was accepted. Central pathology review selected for tumors with > Grade 3 (intense and diffuse) expression of SPARC by immunohistochemistry to be eligible. Nab-paclitaxel was administered as follows: age ≥ 21 and ≤ 40 years: 125 mg/m2 days 1, 8 and 15 in cycles of 28 days; age ≥ 6 months and ≤ 20 years: 240 mg/m2 days 1, 8 and 15 in cycles of 28 days. A 30% ORR was anticipated with a sample size of 25 patients needed to test the hypothesis. Stopping rule was set at 1 response within the first 16 treated pts. If 5 or more successes were observed in 25 pts, the results of the trial will warrant further investigation. Results: Twenty-nine patients were enrolled from June 2017 until October 2019, 11 DSRCT and 18 EwS. Median age was 32 years (range 14-69), and 5 females and 24 males were included, having received a median of 3 previous systemic treatment lines. Patients received a median of 3 cycles of nab-paclitaxel (range 1-17). In the EwS cohort an ORR of 33.3% (all partial responses, median duration 2 months) and 16.7% of stabilizations were achieved. No objective responses were observed among DSRCT pts, but 27.3% of pts achieved a stabilization. Overall, median progression free survival was 2.8 months and median overall survival 12.1 months, with no significant differences between DSRCT and EwS cohorts. Most common grade 3 toxicities were neutropenia (20.7%) and diarrhea (10.3%). Conclusions: Single agent nab-paclitaxel in biomarker selected EwS patients, but not in DSRCT, provided clinically meaningful activity that deserves further development. Nab-paclitaxel had a manageable adverse event profile. Clinical trial information: 2016-002464-14.

Abstract Background Irinotecan-based doublet chemotherapy strategy was standard second-line backbone treatment for patients with oxaliplatin‑refractory metastatic colorectal cancer(mCRC). The aim of this study was to evaluate tolerability and efficacy of raltitrexed combined with irinotecan biweekly administered as the second-line therapy for mCRC patients.Methods The study was a single-center, non-randomized, open-label phase II trial. Patients with mCRC after failure with first-line treatment of oxaliplatin and fluoropyrimidine or its derivatives were enrolled. Irinotecan (180 mg/m2) and raltitrexed (2.5 mg/m2) were given intravenously on day 1. Cycles were repeated every 2 weeks. The primary endpoint was progression-free survival, and the secondary endpoints included overall response rate, disease control rate, overall survival and treatment related adverse events. Results Between December 2012 and October 2016, 35 patients were enrolled. 33 and 35 patients were assessed for response and safety, respectively. The overall response rate (ORR) was 8.6 %, and the disease control rate (DCR) was 71.4%. The median progression-free survival (PFS) was 4.5 months (95% CI 3.8–5.2). The median overall survival was 12.0 months (95% CI 8.5–15.5). Four patients received conversion therapy to no evidence of disease (NED), and 2 patients were still alive with beyond 24 months survival. The most common grade 3/4 hematological adverse events were leukopenia (8.6%), neutropenia (5.7%). The most common grade 3/4 nonhematological adverse events were anorexia (14.3%), vomiting (14.3%), nausea (11.4%) and fatigue (8.6%). Two patients discontinued the protocol treatment because of treatment-related gastrointestinal adverse events. No one died from treatment-related events. The incidence and severity of toxicity was irrelevant to UGT1A1 status.Conclusions The combination of irinotecan with raltitrexed is an active, convenient and acceptable toxic regimen for second-line treatment for mCRC patients, which needs further study as a chemotherapy backbone to be combined with targeted agents in mCRC.Trial registration No. ChiCTR-ONC-12002767. The study was registered with the Chinese Clinical Trial Registry at 29 Octorber 2012, http://www.chictr.org.cn/index.aspx.

44 Background: To evaluate the efficacy and safety of FOLFIRI plus CRT with 5FU as adjuvant treatment for patients with OGC. Methods: Patients received treatment with FOLFIRI (irinotrecan 150 mg/m2, d1, LV 200 mg/m2, d1+2 and 5FU [400 mg/m2/d bolus and 600 mg/m2/d, 22 h infusion, d1+2]) for 2 15-day cycles followed by RT (45Gy) with 5FU continuous infusion (325 mg/m2/d in the 1st and 5th week) administration. Eight additional cycles of FOLFIRI were administered after the completion of CRT. BRCA1, ERCC1, XPD, TOPO-I, TOPO-IIA and B and TS mRNA expression was determined in the primary tumor where available. Results: The median age of the 171 enrolled patients was 62 years, 114 (66%) were males, 136 (79%) had R0 resections and 152 (89%) had at least a D1 resection. Treatment was completed as per protocol in 107 (63%) of the patients. CRT was completed in all but 5 (3%) patients. The median rate of drug exposure was 93% for irinotecan, 87% for 5FU and 91% for LV. The most common grade 3/4 adverse events were neutropenia (32%), febrile neutropenia (3.5%) and diarrhea (7%). After a median follow-up of 45.7 months 84 had relapsed and 70 were deceased. The median disease-free survival (DFS) was 30 months (95% CI: 18-41 months), while the projected median overall survival (mOS) was 53.7 months (95% CI: 30-77 months). The recurrence free probability at 5 years was 44% while the probability of survival at 5 years was 46%. From the studied pharmacogenetic markers only TS low expression was correlated with a trend towards improved DFS and OS in patients with R0 resections. Conclusions: These results show that the administration of FOLFIRI plus CRT with 5FU as adjuvant treatment in OGC is a feasible approach with acceptable toxicity and challenging efficacy which merits further evaluation in a randomized trial.

5059 Background: NGR-hTNF (asparagine-glycine-arginine human tumor necrosis factor) is able to promote antitumor immune responses and to improve the intratumoral doxorubicin (D) uptake by selectively damaging tumor vessels. Methods: OC patients (pts) with progressive disease (PD) after ≥ 1 platinum/taxane regimen and with a platinum free interval lower than 6 months (PFI <6) or ranging from 6 to 12 months (PFI 6-12) received NGR-hTNF (N) 0.8 µg/m2 and D 60 mg/m2 on day 1 every 3 weeks. Primary endpoint of this phase 2 trial was response rate by RECIST criteria with a target of ≥ 6/37 responding pts. Secondary aims were progression free survival (PFS) and overall survival (OS). Results: 37 pts (median age 57 years; PS 0/1 32/5; PFI < 6/6-12 25/12; prior regimens 1-5) were enrolled. Median baseline peripheral blood lymphocyte count (PBLC) was 1.6/mL (interquartile range 1.2-2.1). In all, 177 cycles were given, with 18 pts (49%) receiving ≥ 6 cycles and 12 pts (32%) 8 cycles. Neither grade 3/4 adverse events (AEs) related to N nor increase of D-related AEs were noted. Common grade 1/2 AEs included chills (65%). Eight pts (23%; 95% CI 12-39) had partial response (PR; 2 with PFI < 6 and 6 with PFI 6-12; median duration: 8.2 months). Fifteen pts had stable disease (SD, 43%; 10 with PFI < 6 and 5 with PFI 6-12; median duration: 4.9 months) for an overall disease control (DC, PR+SD) rate of 66%. Mean changes from baseline in target tumor size after 2, 4, 6, and 8 cycles were 2%, -54%, -69%, and -77%, respectively. Median PFS was 5.0 months (95% CI 3.1-6.9) and median OS was 17.0 months (10.4-23.6). In pts with PFI < 6 or 6-12, median PFS were 3.8 and 7.8 months (p=.03) and median OS were 14.3 and 20.1 months (p=.14), respectively. Pts with DC had longer median OS than those with early PD (24.0 and 4.9 months, respectively, p=.02). Longer PFI (p=.03) and higher PBLC (p=.01) were associated with better PFS, while OS correlated only with PBLC (p=.001). In the subset with PFI < 6, pts with PBLC ≥ or < 1.2/mL (1st quartile) had median PFS of 4.9 and 2.6 months (p=.02) and median OS of 15.8 and 4.3 months (p=.0001), respectivel Conclusions: A randomized phase II trial is currently testing D ± NGR-hTNF in pts with PFI < 6 (refractory/resistant). The role of PBLC as blood-based biomarker deserves further investigation.

Abstract Patients with relapsed or refractory multiple myeloma (RRMM) have limited treatment options and poor survival outcomes. The increasing adoption of lenalidomide-based therapy for frontline treatment of multiple myeloma has resulted in a need for effective regimens for lenalidomide-refractory patients. This phase 1b study evaluated daratumumab plus carfilzomib and dexamethasone (D-Kd) in patients with RRMM after 1 to 3 prior lines of therapy, including bortezomib and an immunomodulatory drug; lenalidomide-refractory patients were eligible. Carfilzomib- and daratumumab-naïve patients (n = 85) received carfilzomib weekly on days 1, 8, and 15 of each 28-day cycle (20 mg/m2 initial dose, escalated to 70 mg/m2 thereafter) and dexamethasone (40 mg/wk). Of these, 10 patients received the first daratumumab dose as a single infusion (16 mg/kg, day 1 cycle 1), and 75 patients received a split first dose (8 mg/kg, days 1-2 cycle 1). Subsequent dosing was per the approved schedule for daratumumab. Patients received a median of 2 (range, 1-4) prior lines of therapy; 60% were lenalidomide refractory. The most common grade 3/4 treatment-emergent adverse events were thrombocytopenia (31%), lymphopenia (24%), anemia (21%), and neutropenia (21%). Infusion-related reactions were observed in 60% and 43% of single and split first-dose patients, respectively. Overall response rate was 84% (79% in lenalidomide-refractory patients). Median progression-free survival (PFS) was not reached; 12-month PFS rates were 74% for all treated patients and 65% for lenalidomide-refractory patients. D-Kd was well tolerated with low neutropenia rates, and it demonstrated deep responses and encouraging PFS, including in patients refractory to lenalidomide. The trial was registered at www.clinicaltrials.gov as #NCT01998971.

5513 Background: Adavosertib (AZD1775; A), a highly selective WEE1 inhibitor, demonstrated activity and tolerability in combination with carboplatin (C) in primary PROC. This study (NCT02272790) assessed the objective response rate (ORR) and safety of A in PROC. Methods: Pts with recurrent RECIST v1.1 measurable PROC received A with C, gemcitabine (G), weekly paclitaxel (P), or pegylated liposomal doxorubicin (PLD) in 3- (C) or 4-week (G, P, PLD) cycles (Table). Tumor assessments were performed every 2 cycles until disease progression. Primary objective: ORR; other objectives: disease control rate (DCR), progression-free survival (PFS) and safety. Results: In the 94 pts treated (median treatment duration 3 months; range 0–16 months), outcomes were greatest with A (weeks [W]1–3) + C (Table), with ORR of 67% and median PFS (mPFS) of 10.1 months for this cohort. Most common grade ≥3 treatment-emergent adverse events (TEAEs) are shown in the Table, with hematologic toxicity most notable with A (W1–3) + C. TEAEs led to A dose interruptions, reductions and discontinuations in 63%, 30% and 13% of the whole cohort, respectively. A possible positive relationship between CCNE1 amplification and response warrants further investigation. Conclusions: A shows preliminary efficacy when combined with CT. Pts receiving A (W1–3) + C showed greatest benefit. The increased but not unexpected hematologic toxicity is a challenge and could be further studied to optimize the dose schedule and supportive medications. Clinical trial information: NCT02272790.

Purpose To compare the receipt of clofarabine plus cytarabine (Clo+Ara-C arm) with cytarabine (Ara-C arm) in patients ≥ 55 years old with refractory or relapsed acute myelogenous leukemia (AML). Patients and Methods Patients were randomly assigned to receive either clofarabine (Clo) 40 mg/m2 or a placebo followed by Ara-C 1 g/m2 for five consecutive days. The primary end point was overall survival (OS). Secondary end points included event-free survival (EFS), 4-month EFS, overall remission rate (ORR; complete remission [CR] plus CR with incomplete peripheral blood count recovery), disease-free survival (DFS), duration of remission (DOR), and safety. Results Among 320 patients with confirmed AML (median age, 67 years), the median OS was 6.6 months in the Clo+Ara-C arm and 6.3 months in the Ara-C arm (hazard ratio [HR], 1.00; 95% CI, 0.78 to 1.28; P = 1.00). The ORR was 46.9% in the Clo+Ara-C arm (35.2% CR) versus 22.9% in the Ara-C arm (17.8% CR; P < .01). EFS (HR: 0.63; 95% CI, 0.49 to 0.80; P < .01) and 4-month EFS (37.7% v 16.6%; P < .01) favored the Clo+Ara-C arm compared with Ara-C arm, respectively. DFS and DOR were similar in both arms. Overall 30-day mortality was 16% and 5% for CLO+Ara-C and Ara-C arms, respectively. In the Clo+Ara-C and Ara-C arms, the most common grade 3 to 4 toxicities were febrile neutropenia (47% v 35%, respectively), hypokalemia (18% v 11%, respectively), thrombocytopenia (16% v 17%, respectively), pneumonia (14% v 10%, respectively), anemia (13% v 0%, respectively), neutropenia (11% v 9%, respectively), increased AST (11% v 2%, respectively), and increased ALT (10% v 3%, respectively). Conclusion Although the primary end point of OS did not differ between arms, Clo+Ara-C significantly improved response rates and EFS. Study follow-up continues, and the role of clofarabine in the treatment of adult patients with AML continues to be investigated.
