10520 Background: DFSP is an infiltrative, low-grade, dermal tumor with propensity to recur locally and occasionally metastasize. Translocation between COL1A1 on chromosome 17 and PDGFB on chromosome 22, which results in transcriptional upregulation of PDGFB, is characteristic of DFSP. Autocrine/paracrine PDGFB-mediated activation of PDGFRB drives DFSP proliferation. Two distinct phase II trials of imatinib in patients (pts) with locally advanced or metastatic DFSP were conducted, 1 in North America (SWOG) with confirmed objective response rate and 1 in Europe (EORTC) with 14 week progression-free rate as primary end-points. Methods: Pts with locally advanced or metastatic DFSP were eligible. In the EORTC trial confirmation of t(17;22) by FISH was prospectively required for participation, imatinib was started at 400mg bid, surgery was undertaken after 14 weeks if feasible and response was assessed at 14 weeks. Full accrual was to be 44 pts in one step. In the SWOG trial confirmation of t(17;22) by RT-PCR was performed after enrollment, imatinib was started at 400mg daily and response was assessed every 8 weeks. Full accrual was to be 40 pts in 2 steps. Results: 16 pts were enrolled in EORTC and 8 pts enrolled in SWOG trial. The studies were closed early because of slow accrual and regulatory approval of imatinib in DFSP. Pts age ranged from 24 to 70 yrs, DFSP was located on head/neck, trunk and extremity in 7, 11 and 6 pts, respectively, ranged in size from 1.2–49 cm and was classic, pigmented and fibrosarcomatous DFSP in 13, 1 and 7 pts, respectively. One patient did not have DFSP on central review, lacked t(17;22) and thus was ineligible. Metastases were present in 7 pts involving lung in 6 pts. 11 pts (46%) had partial response, 9 pts had stable disease and 4 pts had progressive disease as best response. Median time to progression was 1.7 yrs. Response and progression-free at 1 yr rates were similar between studies. Imatinib was stopped in 11 pts for progression, 1 pt for toxicity, 2 pts resected free of gross disease and 1 pt withdrew. Conclusions: Imatinib is active in DFSP harboring t(17;22) with an objective response rate approaching 50% and is active in fibrosarcomatous DFSP. Response rates and time to progression did not appear to differ between pts taking 400 mg daily versus 400 mg bid. [Table: see text]

Purpose Dermatofibrosarcoma protuberans (DFSP) is a dermal sarcoma typically carrying a translocation between chromosomes 17 and 22 that generates functional platelet-derived growth factor B (PDGFB). Patients and Methods Two distinct phase II trials of imatinib (400 to 800 mg daily) in patients with locally advanced or metastatic DFSP were conducted and closed prematurely, one in Europe (European Organisation for Research and Treatment of Cancer [EORTC]) with 14-week progression-free rate as the primary end point and the other in North America (Southwest Oncology Group [SWOG]) with confirmed objective response rate as the primary end point. In the EORTC trial, confirmation of PDGFB rearrangement was required, and surgery was undertaken after 14 weeks if feasible. The SWOG study confirmed t(17;22) after enrollment. Results Sixteen and eight patients were enrolled onto the EORTC and SWOG trials, respectively. Tumor size ranged from 1.2 to 49 cm. DFSP was located on head/neck, trunk, and limb in seven, 11, and six patients, respectively, and was classic, pigmented, and fibrosarcomatous DFSP in 13, one, and nine patients, respectively. Metastases were present in seven patients (lung involvement was present six patients). Eleven patients (4%) had partial response as best response, and four patients had progressive disease as best response. Median time to progression (TTP) was 1.7 years. Imatinib was stopped in 11 patients because of progression, one patient because of toxicity, and two patients after complete resection of disease. Median overall survival (OS) time has not been reached; 1-year OS rate was 87.5%. Conclusion Imatinib is active in DFSP harboring t(17;22) including fibrosarcomatous DFSP, with objective response rate approaching 50%. Response rates and TTP did not differ between patients taking 400 mg daily versus 400 mg twice a day.

4509 Background: Urothelial carcinoma (UC) is the third largest cancer type with HER2 positive cancer. RC48-ADC is a novel humanized anti-HER2 antibody-drug conjugate (ADC). This study was to evaluate the activity of RC48-ADC in HER2-positive patients with locally advanced or metastatic urothelial carcinoma (mUC). Methods: This study is an open-label, multicenter, single-arm, non-randomized phase II study. Eligibility criteria include: histologically confirmed UC, HER2-positive (IHC 2+ or 3+), ECOG PS 0-1, treated with ≥1 prior systemic treatment. The patients received RC48-ADC treatment alone (2 mg/kg IV infusion, q2w) until disease progression, unacceptable toxicity, withdrawal, or study termination. The primary endpoint was objective response rate (ORR). Progress-free survival (PFS), overall survival (OS), and safety was also assessed. Results: Patient enrollment for this study was completed in November 2018. A total of 43 patients were enrolled, with a median age of 64 years old. At baseline, most patients (37/43) had visceral metastasis. Fourteen (32.6%) patients had received ≥ 2 lines treatment and 8 (18.6%) patients had prior immune checkpoint inhibitor (CPI) therapy in second line treatment. The objective response rate was 60.5% (95% CI: 44.4%, 75.0%) and the DCR was 90.7% (39/43). As of Jan 23, 2019, the median PFS for the overall study population was not yet reached, and the median PFS was 7.8 months (95% CI: 4.9, 10.7) for the 9 patients who started RC48-ADC prior to Jun 30, 2018. The ORR was 70.6% (12/17) in patients with HER2 FISH+ or IHC3+. The ORR was 64.9% (24/37) in patients with visceral metastasis and was 70.0% (14/20) in liver metastasis patients especially. The ORR was 64.3% in patients post to ≥ 2 lines treatment and 75.0% in patients post to immunotherapy. Common treatment-related AEs were leukopenia (51.2%), hypoesthesia (41.9%), alopecia (41.9%), neutropenia (37.2%), fatigue (34.9%), ALT increase (32.6%), and AST increase (32.6%); Most were Grade 1 or 2. Conclusions: RC48-ADC has demonstrated a clinically meaningful ORR of 60.5% in pretreated HER-2 positive mUC patients including those who underwent failure to the immunotherapy. Clinical trial information: NCT03507166.

PURPOSE Targeted therapies against non–small-cell lung cancer (NSCLC) harboring HER2 mutations remain an unmet need. In this study, we assessed the efficacy and safety of pyrotinib in patients with HER2-mutant advanced NSCLC in a prospective, multicenter, open-label, single-arm, phase II study. PATIENTS AND METHODS Patients with stage IIIB or IV HER2-mutant lung adenocarcinoma who were previously treated with platinum-based chemotherapy were enrolled to receive pyrotinib at a dose of 400 mg/d for 21-day cycles. The primary end point was objective response rate per independent review committee (IRC). RESULTS Between October 20, 2016, and December 10, 2018, 60 patients received pyrotinib monotherapy. At baseline, 58 (96.7%) were stage IV, and 25 (41.7%) received at least 2 lines of prior chemotherapy. As of data cutoff on June 20, 2019, IRC-assessed objective response rate was 30.0% (95% CI, 18.8% to 43.2%). All subgroups of patients with different HER2 mutation types showed a favorable objective response rate. The objective response rates were similar between patients with and without brain metastases (25.0% v 31.3%). The median duration of response was 6.9 months (95% CI, 4.9 to 11.1 months). The median progression-free survival was 6.9 months (95% CI, 5.5 to 8.3 months) per IRC. The median overall survival was 14.4 months (95% CI, 12.3 to 21.3 months). Treatment-related adverse events of grade 3 or 4 occurred in 28.3% of patients, with the most common being diarrhea (20.0%; all grade 3). No treatment-related deaths were reported. CONCLUSION Pyrotinib showed promising antitumor activity and an acceptable safety profile in chemotherapy-treated patients with HER2-mutant NSCLC.

Purpose To assess the efficacy and toxicity of the marine-derived alkaloid trabectedin (ET-743) in patients with advanced ovarian cancer refractory to or experiencing disease relapse after platinum- and taxane-based chemotherapy. Patients and Methods Fifty-nine patients from four institutions either resistant (n = 30) or sensitive (n = 29) to prior platinum and taxanes were treated with a 3-hour infusion of trabectedin every 3 weeks. Patients were monitored weekly for toxicity and restaged every two cycles for response. Response was assessed according to Response Evaluation Criteria in Solid Tumors Group. Results The peer-reviewed objective response rate in platinum-sensitive patients was 43% (95% CI, 23% to 65%) with an estimated median time to progression of 7.9 months (95% CI, 7.5 to 14.1 months); in platinum-resistant patients two partial responses were observed. Responses were durable for up to 12.9 months (median, 5 months). The predominant toxicities at the recommended dose of 1,300 μg/m2 were neutropenia, asthenia, and self-limited increase of aminotransferases never requiring treatment interruption. Conclusion Trabectedin administered as a 3-hour infusion at 1,300 μg/m2 is a safe new drug with promising activity in relapsed ovarian cancer, showing a 43% objective response rate in patients with platinum-sensitive disease, which favorably compares with other salvage treatments and warrants additional development either alone or in combination.

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 Waldenström’s Macroglobulinemia (WM) is a low-grade lymphoplasmacytic disorder associated with an IgM monoclonal protein that may present with anemia, lymphadenopathy, and hepatosplenomegaly. Since combination chemotherapy and Rituximab are both active in this disease, it is possible the response rate can be enhanced by using a combined modality of Rituximab and CHOP. This approach has been used in indolent lymphoma with remarkable results and limited toxicity. Objective: To determine the response rate in previously untreated patients with Waldenström’s Macroglobulinemia receiving rituximab and CHOP. Methods: This was a phase II study of standard R-CHOP in symptomatic WM patients. The study was activated on June 15, 2004 and closed on April 26, 2007 due to poor accrual. The median age of the sixteen patients enrolled was 60 (44–79 years), β2M 3 ug/ml (2.1–7.6), median hemoglobulin was 9 g/dl (7.7–10.9), Viscosity 3.4(1.6–10), and IgM 6389 (3229–13300 mg/dl). The most common symptoms were Fatigue (13/16), visual disturbance (7/16) and parasthesias or painful/numb feet (6/16). Only one patient had bulky adenopathy (6.3%). Results: Of 16 patients treated, 5 patients have no response data available (it will be presented at the meeting). Objective response was 91% (90% CI: 63.5% ∼ 99.5%) and 1 patient had a minor response with an overall response rate of 100%. Median time to response was 1.6 months from registration and median time to maximum response was 2.1 months. Median duration of response has not been reached. The median follow up time of the 16 patients was 18.3 months with a range of 3.6–24.8 months. Among the 16 treated patients, there were 8 (50%, 90% exact binomial CI: 27.9%∼72.1%) grade 4 neutropenia. 8 patients experienced grade 3 lymphopenia (50%, 90% exact binomial CI: 27.9%∼72.1%). Only 2 grade 3 febrile neutropenia were noted. As of August 4, 2007, none of the 16 patients has died. R-CHOP is a promising regimen in the treatment of patients with Waldenström’s Macroglobulinemia. To succeed in completing clinical trials in this rare disease better international collaboration and involvement in advocacy groups are required.

4087 Background: A phase II study (ASCO 2004) established that the combination of UFT (tegafur-uracil) with LV and irinotecan (TEGAFIRI) could be safely administered to pts with unresectable mCRC, with an objective response rate (ORR) of 34% and a median time to progression (TTP) of 5.7 months. We initiated CETUFTIRI, a phase II study, to evaluate the efficacy and tolerability of cetuximab added to TEGAFIRI in chemonaïve pts with unresectable mCRC. Methods: Patients in this single-stage study were aged =18 years, with histologically or cytologically confirmed, bidimensionally measurable mCRC, ECOG performance status 0 or 1, and adequate bone marrow, renal, and hepatic function. EGFR expression was not an inclusion criterion. Treatment consisted of UFT 250 mg/m2/day d1–14, LV 90 mg/day d1–14, and irinotecan 250 mg/m2 d1 every 3 weeks, plus cetuximab 400 mg/m2 week 1 then 250 mg/m2 weekly thereafter. The primary endpoint was ORR and the planned sample size was 61 pts. The study is now closed to accrual. Results: To date, 48 patients are evaluable for safety and 31 are evaluable for efficacy. Patient characteristics (n=48): median age 65 years (range 45–84 years); ECOG PS 0/1: 73/27%; male 65%; tumor sites: colon 69%; rectum 17%; junction 14%; liver metastasis 83%; lung metastasis 46%; other 27%. Adverse events per patient (n=48) after a total of 230 cycles were: grade G3 mucositis 10%; G3/4 neutropenia 10%; G3 nausea/vomiting 8%; G3 asthenia 6%; febrile neutropenia 6%; G3 hypokalemia 6%; G3/4 anemia 4%; G3 diarrhea 2%; acne-like rash G1/2 50% (G3 4%); infusion- related reaction to cetuximab 6%. Two of 31 evaluable pts had a complete response and 11 had a partial response, for an ORR of 42%; 5 pts had stable disease (16%) and 11 pts had progressive disease (35.5%). An independent radiologist review is planned for all 61 pts included up to December 2006. Conclusions: The CETUFTIRI combination seems to have an acceptable toxicity profile with an attractive objective response rate in the first-line treatment of pts with mCRC. No significant financial relationships to disclose.

2063 Background: Meningiomas account for 15%-18% of CNS tumors. Although benign, recurrence is seen in 16%-39% of cases, depending on the extent of resection possible. Tumor location may make further resection hazardous. Chronic hydroxyurea (HU) was reported to produce well documented objective responses in a small series of patients, with gradual regression occurring over 6–10 months. Induction of apoptosis was furthermore demonstrated with HU in primary benign meningioma explant cultures. The S9811 phase II trial was undertaken to estimate the objective response rate, if any, of unresectable benign meningioma to this HU regimen. Methods: Eligibility required unresectable, measurable, residual or recurrent, histologically-proven benign meningioma. Progressive tumor or progressive neurologic deficit was required. No prior cytotoxics, no radiation therapy for >1 year. Age > 18, adequate hematologic reserve, PS 0–2. HU 20 mg/kg/day po was given for up to 2 years if there was no progressive disease. Single-stage accrual of 38 pts would have allowed detection of 5% null hypothesis response probability vs. 20% with 90% power; the 28 pts actually accrued provide 81% power. Results: Between November 98 and June 2005, 29 pts were accrued, with study closure due to slow accrual. 1 ineligible. Response assessment showed CR+PR 0% (95% CI 0–12%); SD 71% (95% CI 51–87%); PD 21% (95% CI 8–41%); undetermined 7%. Median PFS was 27 months. (95% CI 12–29 months.); 3-year PFS 43% (95% CI 25–61%). Median OS has not been reached. Seven patients were removed from study for toxicity (5/7 hematological). Toxicity was mainly hematologic: 11/28 (39%) grade 3, 2/28 (11%) grade 4. Grade 3 non-hematologic toxicity was seen in 7/28 (25%). Conclusions: Chronic HU therapy for unresectable benign meningioma resulted in an estimated objective response rate of < 12%. Whether the stable disease rate seen differs in any way from what can be expected from the natural history of meningioma cannot be determined from this phase II study design. No significant financial relationships to disclose.

From May 1980 to November 1981, 51 consecutive patients with locally advanced, recurrent or metastatic head and neck squamous carcinoma were treated with 2 successive outpatient chemotherapeutic regimens including adriamycin, cyclophosphamide, vincristine, bleomycin, methotrexate and 5-fluorouracil with or without mitomycin-C. A 34% objective response rate was obtained with acceptable toxicity and good patient compliance. The presence of mitomycin-C did not influence response rate. Median survival was 9 months.
