1018 Background: Constitutive activation of mTOR and amplified PI3K/Akt/mTOR signaling are common in MBC, and increase as treatment-resistance is acquired. Everolimus (E), an mTOR inhibitor, has single agent activity, combines well with paclitaxel (P) and bevacizumab (B), and prolonged PFS when added to AI therapy in BOLERO-2. In this randomized phase II trial, E was added to P/B as first-line treatment of HER2-negative MBC. Methods: Women with untreated HER2-negative MBC were randomized (1:1) to P 90mg/m2 IV (days 1, 8, and 15) and B10mg/kg IV (days 1 and 15) q28 days with E 10mg PO (Arm 1) or placebo PO (Arm 2) daily. Response assessment was performed q8 weeks until progression or intolerable toxicity. Primary endpoint was PFS. Secondary endpoints: safety, overall response rate, response duration, overall survival. 110 pts allowed detection of improvement in median PFS from 11 to 16 months with 70% power. Results: Between 8/2009 and 6/2011, 112 pts were randomized (Arm 1=55; Arm 2=57). Median age: 58 years (range: 25-79). 88% were ER+ or PR+. Pts received a median 5 treatment cycles (range: <1- 26+); 18 (16%) pts remain on treatment (Arm1, 9; Arm 2, 9). Median PFS were 8.8 months (Arm 1) and 7.1 months (Arm 2) (95% CIs 7.4-9.6; 5.5-9.1 months, p=0.79, HR 0.94). Complete responses were observed in 5% [Arm1, 4 (7%); Arm 2, 2 (4%)] with partial responses in 49% [Arm1, 29 (53%); Arm 2, 26 (46%)]. Responses rates in taxane pretreated pts Arm 1 22%, Arm 2 12%. Hematologic toxicity was similar in both arms; grade 3 mucositis occurred in 13% of E pts. Dose reductions (47% vs 25%) and interruptions (42% vs 26%) were more frequent with E due to mucositis and rash. Treatment discontinuation rates were similar. Conclusions: The addition of E did not result in a significant improvement in the efficacy of weekly paclitaxel/bevacizumab in the first-line treatment of HER2-negative MBC although response rates and median PFS were better with E. Possible explanation for these results may include lower dose intensity in the E arm, treatment of less resistant pts, or intrinsic differences in E activity when added to antiestrogen vs chemotherapy.

7081 Background: Cisplatin is one of the most active drugs available in MPM while bortezomib has shown some activity in single agent phase II studies against MPM. This was a prospective phase II study of cisplatin and bortezomib (CB) in the first line treatment of MPM. Methods: Patients with histological proven MPM, with performance status (PS) 0/1, were eligible. The doses were cisplatin 75mg/m2 /3 wks and bortezomib 1.3mg/m2 day 1, 4, 8, 11 every 3 wks. The primary end-point was progression free survival rate at 18 wks (PFSR=18). The 2-stage Simon design (a=0.1; b = 0.05, P0=0.50 and P1=0.675) was used. In the first step of the study 37 eligible patients were planned. If more than 19 patients were alive and free of progression at 18 wks the total sample size was increased to 76 eligible patients. Results: Between 2007 and 2010 82 patients were entered. The median follow-up time is 32.3 months The median age was 55 years (range: 22-77yrs), male/female: 55/27 , PS 0/1: 9/73, Stage T1: 10%; T2: 42%, T3: 25%; T4: 23% and N0: 57%; N1: 4%; N2: 33%; N3: 6%. The median number of cycles received was 4 and 38% received 6 cycles. Cisplatin/ bortezomib dose intensity was 98/ 80%. Toxicity (grade 3/4): neutropenia 10%, thrombocytopenia 11%, anaemia 1%. Grade 3-4 hyponatraemia/ hypokalaemia occurred in 46/ and 17%. Grade 2 tinnitus, grade 3 fatigue occurred in 16%, and 12%, of patients. Motor/sensory/other neurotoxicity was grade 1: 6/28/7%, grade 2: 2/26/2% and grade 3: 1/7/2% respectively. There were 2 toxic deaths at 32 and 74 days due to acute pneumonitis and cardiac arrest. The PFRS-18 (including symptomatic progression) was 53% (80% confidence intervals, CI, 42-64%). The overall survival was 13.5 months (95% CI 10.5-15) with 56% (95% CI 44-66%) alive at 1 year. The PFS was 5.1 months (95% CI 3.3-6.5). Conclusions: On the basis of the PFRS-18, the null hypothesis could not be rejected, although CB gave predictable toxicity and was as active as other reported regimens in MPM.

8080 Background: Single agent rituximab produces a high response rate when used as first-line treatment, and maintenance rituximab prolongs remission duration. Active immunotherapy is a promising treatment approach, when administered following remission induction by initial therapy. In this phase II trial, we evaluate the feasibility, toxicity, and efficacy of administering concurrent maintenance rituximab plus Id-KLH vaccine in pts with low-grade NHL. Methods: Pts with previously untreated low-grade NHL (grade 1/2 follicular or SLL) who were judged to be candidates for single agent rituximab therapy were eligible. All pts had initial biopsy for production of the Id-KLH vaccine. All pts received rituximab 375mg/m2 IV, weekly × 4. Pts with CR/CRu, PR, or stable disease at 8 weeks proceeded with maintenance rituximab (standard 4 week courses at 6 month intervals for 3 courses) and Id-KLH vaccination (Id-KLH 1cc day 1; GMCSF 250μg SQ days 1–4) monthly × 8, beginning month 3, then every 2 months during the second year. Pts were monitored for response rate, progression- free survival, and toxicity. Results: To date, 36 of a planned 56 pts have been enrolled. Idiotype vaccine was successfully manufactured in 27 of 32 pts (84%), with 4 in production. Of the 27 pts for whom Id-KLH was successfully manufactured, 2 progressed during rituximab. 19 of 25 pts (14FL;5SLL) have had response determined after rituximab: 8 PR (42%), 11 stable (58%; 4 of 5 SLL). Pts have now received rituximab maintenance therapy plus Id-KLH for durations of 6 - 34 months. 6 of 19 pts (3 SLL) progressed at months 5, 6, 9, 9, 10, and 12, respectively. Treatment has been well tolerated, with no unusual toxicities observed. Rituximab-related hypotension and atrial fibrillation occurred in 1 pt. The most common Id-KLH related adverse event has been injection site reaction. Conclusions: Concurrent maintenance therapy with rituximab plus Id-KLH is safe and well tolerated. At present, 6 of 25 pts (24%) have progressed (including 3 of the 5 SLL pts) with a median followup of 19 months. This trial is continuing. No significant financial relationships to disclose.

11023 Background: Imatinib (IM) is the standard first-line treatment for advanced GIST and regorafenib (REG) is approved for third line therapy. We studied if an alternating regimen of two tyrosine kinase inhibitors, IM and REG, delays resistance to IM and improves outcomes. Methods: ALT-GIST (NCT02365441) is a randomised non-comparative phase II trial to investigate the efficacy of an alternating regimen (ALT) of 21-25 days of IM 400mg orally daily followed by a 3-7-day gap for washout followed by 21 days of REG 160 mg orally daily and a 7-day gap for washout. The control arm was continuous IM 400mg daily. Delayed recruitment led to revised endpoints of activity and safety. To assess clinical activity, the best objective tumor response (OTR) at 9 months was deemed to be an appropriate endpoint in the revised protocol. Results: Seventy-six eligible patients (ALT 40, IM 36) enrolled from June 2015 to September 2018 were evaluable for the OTR. The patients (pts) were predominately male (n = 51, 67%). Median age was 58 (range, 24-81) in the ALT arm and 65 (range, 35-82) in the IM arm. KIT was mutated in 63, PDGFR in 2, and wildtype in 5 tumors. Relative dose intensity in the ALT arm 102% for IM and 82% for REG and was 93% in the IM arm. Median follow-up time was 19.3 months (range 6.0-40.0).The best responses to the ALT and IM treatments were similar at 9 months, 1 vs 0 pts had complete response, 23 vs 23 partial response, 15 vs 13 stable disease, and the OTR was 60% (95% CI, 45-74%) and 64% (95% CI, 48-78%), respectively. Seven (18%) pts in ALT arm and 10 (28%) in IM arm discontinued treatment due to progressive disease. Seven pts (18%) in the ALT arm stopped protocol therapy due to unacceptable toxicity, and none in the IM arm. Fifteen (38%) pts in the ALT arm and 14 (38%) in the IM arm had serious adverse events, mostly grade 3. Progression free survival (PFS) at 1 year was ALT 0.86 (95%CI:0.69,0.94) and IMI 0.83 (95% CI 0.65-0.92), p logrank = 0.57. Conclusions: There was no meaningful difference in the primary endpoint of OTR and in PFS between the groups in this first analysis of ALT-GIST, and no unexpected safety signals. The study is ongoing and other endpoints will be reported in due course. Clinical trial information: ACTRN12614000950662.
