Bevacizumab (B) plus everolimus (E) in refractory metastatic colorectal cancer (mCRC)

4080 Background: For patients (pts) with mCRC, no standard therapy exists after progression on 5-FU, oxaliplatin, irinotecan, bevacizumab, and/or cetuximab/panitumumab. Preclinical data demonstrate combined VEGF and mTOR inhibition has greater anti-angiogenic and anti-tumor activity than either monotherapy. B inhibits VEGF; E inhibits mTOR. Phase I data in patients demonstrated B + E was safe and activity was seen in several pts with refractory mCRC. Methods: 25 pts with refractory mCRC were enrolled in an expanded cohort of B + E. Doses: B 10 mg/kg q2 wks; E 10 mg PO QD. Blood, skin, and tumor biopsies pre- and on-treatment were collected for markers of response and resistance. Results: At this time, 19 pts (10M: 9F) are evaluable for toxicity; 17 for efficacy. Median age 57 years (range 35–78). Median number prior regimens 3. All pts had prior B exposure; 17 pts had progressive disease on prior B-based therapy. There was one Grade (Gr) 4 adverse event (AE) of hypokalemia. Grade 3 AE related to treatment were bowel perforation/fistula, (n=2), hyperglycemia (3), hypokalemia (3), hypertension (2), fatigue (1), alk phos elevation (1; lab only), hypoalbuminemia (1), and volume depletion (1). Other events of interest were: Gr1–2 mucositis (n=10), Gr1 hyperlipidemia (11). Of 17 pts evaluable for response, 4 pts had SD as best response (median 24 wks, range 17–31+ wks); there were 3 minor responses in pts who had progressed on B (median 16 wks, range 16–27 wks). No CR or PR were seen. Biomarker data is pending. Conclusions: B+E has activity in refractory mCRC in pts who had progressed on a B-based regimen, suggesting B+E may overcome resistance to B. Patient accrual is continuing and updated data will be presented. [Table: see text]

Abstract Background: The combination of DVd with Thalidomide (T) results in a high response rate (greater than 80% with about 50% of patients achieving a CR or NCR) in multiple myeloma. Revlimid, an immunomodulatory drug (IMiD) is active in patients with MM. We previously reported on a phase I trial of DVd-R in patients with MM, in which the maximum tolerated dose of R was 10mg daily. Methods: The DVd-R regimen was given as follows: on day 1 D was given at 40 mg/m2 IVPB; V at 2 mg IVP; d at 40 mg PO daily for 4 days, R was started at 10mg daily. R was given for 21 days consecutively. For the first cycle R was started 7 days prior to chemotherapy, while it was started on day 1 on subsequent cycles (cycle 1 was 35 days). DVd was planned every 28 days for 2 cycles after best response or a minimum of 4 cycles. Maintenance therapy consisted of R +/− Prednisone 50 mg Qod. All patients received amoxicillin, acyclovir and aspirin 81mg prophylactically. Responses were assessed based on the criteria set forth by SWOG. Patients: The study accrued 58 patients to date (36 refractory and 22 relapsed patients), 45 are evaluable for response. The median patient age at the start of the study is 62 years and 74% are males. The median number of prior chemotherapeutic regimen is 3 (range 1–7), 67% of patients had progressed after a Thalidomide containing regimen, 70% had received a VAD like regimen and 17% had received a prior autologous stem cell transplant. The median time from diagnosis to study entry is 39 month (range 5–182). Eighty six percent had Durie Salomon stage III. The mean serum B2microglobin was 6.6mg/dL (s.d.4.2). Results: The median number of cycles of DVd-R delivered was 4. Of evaluable patients, 6 patients had a CR (13%), 5 had a NCR (11%), 16 had a PR (35%), 11 had stable disease (24%), and 7 had progressive disease (15%) as their best response. The median time to best response was 38 days. After a median follow up of 7.3 month (range 0–24 months), 23 patients had progressive disease and 16 patients had died. Fifty two percent of refractory patients (19/36) had a response on DVd-R. Grade 3 and 4 leukopenia occurred in 24% and 15% respectively, however febrile neutropenia occurred in only 1 patient. Grade 3 and 4 infections occurred in 26% and 3% respectively (all but one were pneumonia). Grade 3 thrombocytopenia occurred in 20%. Venous thromboembolic events occurred in 5 patients (9%) (2 patients with pulmonary embolus and 4 with deep venous thrombosis). Grade 3 neuropathy occurred in 3 patients (no patients had grade 4 neuropathy). Two patients developed grade 3 tumor lysis syndrome. Conclusion: DVd-R is an effective chemotherapeutic regimen in patients with RMM who progressed or did not respond to VAD like regimens or to Thalidomide containing regimens, produces a high response rate among chemotherapy resistant patients, and has a manageable toxicity profile. The results will be updated at the time of the meeting.

Abstract Background Glioblastoma (GBM) is the most common malignant brain tumour in adults with a median survival from progression of 8 months. A recent phase 1 study of temozolomide (TMZ) and 1:1 CBD:THC (Sativex) offers evidence of efficacy in patients with recurrent GBM (NCT01812603). Methods All patients receiving TMZ & Sativex (75mg/m2 daily d1 – 21 q28; Sativex continuously) for relapsed GBM or grade 3 astrocytoma at our centre were identified. Patient, tumor and treatment characteristics were recorded, and response based on sequential MRI scans using modified RANO criteria assessed. Results 13 patients were treated over 18 months. The median age was 56; 69% were male. All had received initial chemo-radiotherapy (12 patients: 60 or 59.4Gy/30–33#; 1 patient: 45Gy/15#). 6 patients underwent reresection at recurrence. 4 patients were treated at first progression, 7 at second progression, and 2 at third or later progression. The median number of cycles of TMZ and sativex was 2. The combination treatment was tolerated well by all patients treated, with no Grade 3 or 4 toxicities, the only complaints being of discomfort in mouth after spray and ‘spaced out feeling’. Patients stopped treatment due to evidence of progressive disease on sequential MRI sign or physical deterioration. Median Overall Survival (OS) from initiation was 5.9 months (177 days); Progression Free Surival (PFS) at 3 months was 50%. Conclusion These results highlight some discrepancies in OS in comparison to the previous trial (NCT01812603), but our patients were treated at second/ third recurrence. We agree that the combination is well tolerated.

Abstract Background Alteration of the PI3K/AKT/mTOR pathway is a common genomic abnormality detected in triple-negative breast cancer (TNBC). Everolimus acts synergistically with eribulin in TNBC cell lines and xenograft models. This phase I trial was designed to test the safety and tolerability of combining eribulin and everolimus in patients with metastatic TNBC. Methods The primary objective of this study was to evaluate the safety and toxicities of the combination. Patients with metastatic TNBC who had up to four lines of prior chemotherapies were enrolled. The combination of eribulin and everolimus was tested using three dosing levels: A1 (everolimus 5 mg daily; eribulin 1.4 mg/m2 days 1 and 8 every 3 weeks), A2 (everolimus 7.5 mg daily; eribulin 1.4 mg/m2, days 1 and 8 every 3 weeks), and B1 (everolimus 5 mg daily; eribulin 1.1 mg/m2 days 1 and 8 every 3 weeks). Results Twenty-seven patients with median age 55 years were enrolled. Among 8 evaluable patients who received dose level A1, 4 had dose-limiting toxicities (DLTs). Among 3 evaluable patients treated with dose level A2, 2 had DLTs. Among 12 evaluable patients who received dose level B1, 4 had DLTs. The DLTs were neutropenia, stomatitis, and hyperglycemia. Over the study period, 59% had a ≥ grade 3 toxicity, 44% had ≥ grade 3 hematologic toxicities, and 22% had grade 4 hematologic toxicities. The most common hematological toxicities were neutropenia, leukopenia, and lymphopenia. Thirty-three percent had grade 3 non-hematologic toxicities. The most common non-hematological toxicities were stomatitis, hyperglycemia, and fatigue. The median number of cycles completed was 4 (range 0–8). Among 25 eligible patients, 9 patients (36%) achieved the best response as partial response, 9 (36%) had stable disease, and 7 (28%) had progression. The median time to progression was 2.6 months (95% CI [2.1, 4.0]), and median overall survival (OS) was 8.3 months (95% CI [5.5, undefined]). Conclusion Eribulin 1.1 mg/m2 days 1 and 8 every 3 weeks with everolimus 5 mg daily was defined as the highest dose with acceptable toxicity (RP2D). The combination is safe, and efficacy is modest. A post hoc analysis showed that participants that used dexamethasone mouthwash stayed on treatment for one additional cycle. Trial registration ClinicalTrials.gov, NCT02120469.

PURPOSE To determine the response rate, survival, and toxicity of the new anticancer agent, irinotecan (CPT-11), in the treatment of metastatic colorectal cancer. PATIENTS AND METHODS Forty-one chemotherapy-naive patients with measurable metastatic colorectal cancer were treated with a 90-minute infusion of irinotecan 125 mg/m2 administered weekly for 4 weeks every 6 weeks. Pretreatment tumor biopsies to assess topoisomerase-I (Topo-I) activity were obtained from 11 patients. The pharmacokinetics for irinotecan and its active metabolite, SN-38, were determined in 18 patients. RESULTS Thirteen of 41 patients (32%) had a partial response (PR; 95% confidence interval, 18% to 46%). The median response duration was 8.1 months (range, 4.0 to 16.0) and the median survival time was 12.1 months (range, 2.1 to 21.7) for all 41 patients. Grade 3 or 4 toxicities were diarrhea (29% of patients) and neutropenia (22% of patients). Grade 3 or 4 diarrhea was substantially more prevalent in the initial 18 patients on study, with an incidence rate of 56%; a significant reduction in the incidence of severe diarrhea to 9% was noted with strict adherence to an antidiarrheal regimen of loperamide and diphenyldramine. No correlations were seen between pharmacokinetics of irinotecan/SN-38 and the clinical parameters of response, survival, or incidence of diarrhea. CONCLUSIONS Irinotecan has activity in the treatment of patients with metastatic colorectal cancer. Strict adherence to an antidiarrheal regimen of diphenhydramine/loperamide significantly reduced the incidence of diarrhea; the agent was thereafter well tolerated in the majority of patients.

Abstract Background: Bortezomib as a single agent has known efficacy in the treatment of relapsed multiple myeloma. The overall response rate (CR+PR+MR) was 35% in the SUMMIT study and 46% in the APEX study. In-vitro studies including our own have demonstrated potent synergy with other chemotherapeutic agents such as melphalan. It therefore follows that responses to bortezomib may be further improved by the combination of such drugs. Aims: The primary objectives of this Phase I/II study was to assess the safety, tolerability and response rates in patients with relapsed multiple myeloma; secondary objectives being time to progression (TTP) and overall surival (OS). Methods: This was a multi-centre, non-randomised trial for patients with relapsed myeloma. Patients received bortezomib 1.3mg/m2 on days 1,4,8 and 11 of each 28 day cycle with melphalan on day 2 at increasing dose levels. This was initially at 10mg/m2, but due to cytopenias subsequently at 2.5 and 5mg/m2 (levels 1a, 1 and 2) and we plan to escalate to 7.5mg/m2. Up to 8 cycles were given with dexamethasone added for stable or progressive disease after 4 or 2 cycles respectively. Responses were determined by EBMT criteria. Results: To date, 18 patients have been enrolled (12 male 6 female; median age 60 [range 44–73]; median number of prior therapies 3 [range 1–5] of which 17 have had at least one autologous stem cell procedure with high dose melphalan; 10 prior thalidomide and 2 prior bortezomib). 12 patients received melphalan at 10mg/m2 but due to unacceptable delays predominantly due to thrombocytopaenia, subsequent treatment levels commenced at 2.5mg/m2. The median number of cycles completed thus far is 4 (range 0–8) and of the 16 evaluable, the overall response rate (CR+PR+MR) across all treatment levels was 50% rising to 75% following the addition of dexamethasone as per protocol. At level 1a (melphalan 10mg/m2 ,N=12, median number of cycles completed =5) the best responses (with dexamethasone as indicated) were: 1CR, 1 VGPR, 5 PR, 2 MR; at level 1 (melphalan 2.5mg/m2, N=4) 1 PR, 2 MR (after 2 cycles only). The median time to any response was 1 cycle (range 1–3 ). Three patients have progressive disease, but the median TTP and OS have not yet been reached (median follow-up 3 months). Non-haematological toxicities have been modest with 7 SAEs reported of which only 1 was possibly drug related (myocardial infarction), and 4 episodes of Grade 3 neuropathy (2 resulting in study withdrawal). The commonest grade 3–4 haematological toxicity was thrombocytopaenia (N=10) complicated by bleeding in one patient, followed by neutropenia (N=6). Summary: The combination of bortezomib and intravenous melphalan can be given safely to patients with relapsed multiple myeloma and dose escalation is ongoing. Myelosupression was the commonest grade 3–4 adverse event. A response rate of 50% was seen, which was further improved to 75% with the addition of dexamethasone. This combination may therefore result in higher responses than single agent bortezomib in heavily pretreated patients.

Abstract Abstract 3055 Lenalidomide (Revlimid®) and dexamethasone is an effective regimen for relapsed/refractory (rel/ref) multiple myeloma (MM) patients (pts) with an overall response rate of 60% and median time to progression of 13.4 months (Dimopoulos ME, et al. Leukemia 2009; 23: 2147-52). We combined lenalidomide with the alkylating agent combination of cyclophosphamide and prednisone—an older regimen with minimal cumulative myelosuppression and good activity as second or third line therapy (Trieu Y, et al, Mayo Clin Proc 2005; 80: 1582). The CPR regimen consisted of cyclophosphamide (CY) on days 1, 8, and 15, lenalidomide on days 1–21 and prednisone 100 mg q 2 days in a 28-day cycle. ASA 81 mg/day was given as DVT prophylaxis. Three dose levels were evaluated using a 3 × 3 dose escalation design. Thirty-two pts were entered between 11/2007-06/2009; median age was 64 (42-80) yrs, 60% were male, and immunoglobulin isotype was IgG in 19 (62%), IgA in 8 (25%) and light chain in 4 (13%) pts. Median β2-microglobulin level was 257 (92-767) nm/L, albumin 39 (34-48) g/L, creatinine 83 (50-126) μmol/L, platelet count 355 (75-479) × 109/L and ANC 2.5 (1.1-6.1) × 109/L. The median number of prior regimens was 2 (1-5). Prior therapy included: ASCT (single in 91%; double in 19%), thalidomide (28%) and bortezomib (50%). FISH cytogenetics were available in 13 pts; 1 had del 13q but none had t(4;14) or del p53. Table 1 summarizes protocol treatment delivered. Table 1. Dose level N Cyclophosphamide dose (mg/m2) Lenalidomide dose (mg) Prednisone dose (mg) Median # cycles given 1 3 150 15 100 12 (12–34+) 2 3 150 25 100 10 (9–23) 3 26 300 25 100 17 (5–28+) 1–3 (All) 32 150–300 15–25 100 19 (5–34+) Dose limiting toxicity was not observed during cycle 1 at any dose level. Grade 3–4 toxicities during the trial included: thrombocytopenia in 7 (22%) and neutropenia in 9 (29%), managed with dose reduction and/or growth factors; five episodes of febrile neutropenia occurred, all at dose level 3. In cohort 3, other grade 3–4 non-hematologic toxicities included 1 episode each of abdominal pain/bacteremia, hypokalemia, fatigue, sick sinus syndrome, cardiac amyloidosis, perforated diverticulum and 2 episodes of DVT. Two heavily pretreated pts developed 2° MDS, including 1 previously treated for lymphoma, 43 and 190 mos after the diagnosis of MM. The best response using modified EBMT criteria was documented at a median of 7 (1-26) cycles and included the following: dose level 1 (1 CR, 2 PR); dose level 2 (1 VGPR, 2 PR); dose level 3 (4 CR, 14 VGPR, 11 PR, 1 MR and 1 stable disease). At a median F/U of 16 (5-34) months, 13 pts remain on study and 18 have progressed at a median of 10 (2-23) mos; 1 was lost to F/U and 9 have died of progressive MM. The 1-year actuarial OS and PFS rates are 93% (95% CI 76–98%) and 78% (95% CI 60–89%), respectively. We conclude: 1) the combination of full doses of the agents in CPR can be given in a 28 day cycle with an acceptable safety profile; 2) the objective response rate (CR + PR + MR) in all 32 pts to date is 94%; 3) the 1-year OS of 93% and PFS of 78% compare favorably with other 3-drug combinations in rel/ref MM pts; 4) further evaluation of this regimen in newly diagnosed pts would be of interest.

3081 Background: GX15–070 is an antagonist of the BH3-binding groove of the bcl-2 family of anti apoptotic proteins. GX15–070 activates apoptosis in vitro and exhibits clinical activity in chronic lymphocytic leukemia (O’Brien et al, ASH 2005) with a recommended phase II dose of 28 mg/m2 every 3 weeks with DLT of grade 3 infusional CNS toxicities. Methods: In a standard titration design, 4 cohorts of 3 patients (pt) were treated with 5mg/m2 - 14 mg/m2 IV infused over 3 hours, weekly. Each cycle of therapy consisted of 4 weekly infusions. Pharmacokinetics (PK) and pharmacodynamic (PD) response based on plasma oligonucleosomal DNA levels were evaluated. Results: N=15 pts were treated. Median age was 58 (range 24–71). Median number of prior regimens was 4 (range 1–11). A total of 105 infusions (26 cycles) was administered. GX15–070 underwent first order elimination kinetics with a short initial distribution phase (α t1/2=0.6 h), followed by a longer elimination γphase (t1/2=43.8 h). At the 14 mg/m2 dose level, median C max and AUC values were 98 ng/ml and 276 ng.hr/ml, respectively. The coefficient of variation was low at 38%. Adverse events have mostly been observed during or shortly after the infusion and have been transient. The most common pertain to the central nervous and gastro-intestinal system (drowsiness, euphoria, ataxia, and abdominal pain). Most toxicities were mild to moderate, with the exception of grade 3 pain experienced by 2/2 pts with Hodgkin’s disease, that resolved rapidly but resulted in treatment discontinuation in 1 patient. One episode of Grade 3 infusional CNS toxicity was reported at 14 mg/m2 requiring the inclusion of 6 patients with no further DLT. No neutropenia, thrombocytopenia or lymphopenia have been reported. The MTD has not been reached. Mean increase in plasma oligonucleosomal DNA was 36 fold (range 0–182 fold) over baseline. Best response to treatment to date : SD ≥ 8 weeks (4); PD (5); too early (6). Conclusion: Weekly GX15–070 as been well tolerated at doses showing biological activity. Dose escalation will be pursued up to 28 mg/m2 weekly. No significant financial relationships to disclose.

15111 Background: The aim of this phase II study was to determine whether second line therapy with single agent irinotecan could provide any clinical benefit in patients with gemcitabine- pretreated advanced pancreatic cancer. Methods: From January 2004 to October 2006, patients with advanced pancreatic cancer previously treated with gemcitabine alone or combination were treated with single agent irinotecan(150 mg/m2, biweekly), until unacceptable toxicity or disease progression. Primary endpoint was response rate with single stage design. Results: Twenty-eight patients were enrolled(22 male, 6 female, median age : 54.5 years (39–76)). Nine patients are still alive and 3 remain on therapy with stable disease. The median number of cycles was 3.5(1–12). Twenty-four patients were assessable for toxicity and 21 for response. The most common toxicities was diarrhea (grade 3, 12.5%). Grade 3 neutropenia in 1 patient was observed. Other hematological and non-hematological toxicities were mild and manageable. Partial responses were observed in 3 patients (3/21, 14%). An additional 9 patients (9/21, 43%) had stable disease as their best response. 12 patients have progressed with a median time-to-progression of 4.0 months. Conclusions: Single-agent irinotecan was tolerated with manageable toxicity, offering encouraging activity as second-line treatment of patients with advanced pancreatic cancer, refractory to gemcitabine. No significant financial relationships to disclose.

Methods: Eligible pts had to have histologically proven recurrent or metastatic CRC,not having previously received oxaliplatin as palliative chemotherapy,ECOG PS = 2,age:18∼70,and adequate hematological,renal and hepatic function.After written informed consent,pts were randomized to L-OHP:130 mg/m2 d1 + RTX: 3 mg/m2 d1 (Arm A) or + LV: 200 mg/m2 + 5FU:375 mg/m2 d1–5 (Arm B). Results: Between Jan 2005 and July 2006, 216 pts were enrolled at 15 centers in China.112 pts (mean age: 55.0 (19∼70), M/F: 57/46, PS 0/1/2: 46/53/13) were randomly assigned to A and 102 (mean age: 54.2(22∼70), M/F: 54/46, PS 0/1/2: 44/59/9) to B. 203 pts were eligible for response evaluation (A:103, B:100).The median number of cycles was 4 (1∼6) in A and 3 (1∼6) in B (P=0.1431).The RR was 29.1% (CR:2, PR:28, SD:50 , PD:23) in A and 17.0% (CR:2, PR:15, SD:46 , PD:37) in B (P=0.0437).The disease-control rate was 77.7% in A and 63.0% in B (P=0.0237). After a median follow-up of 10 months (4–16.5),92 pts had had progression of disease (40 in A and 52 in B); 73 deaths had occurred (35 in A and 38 in B), median time to progression was not reached. Following-up is ongoing.The median QoL scores for the two arms were comparable. 214 were included in the safety analyses (A:112, B:102). There was a higher incidence of neutropenia (48.2% verse 29.4%, P=0.005) and transaminase increase (49.1% verse 35.3%, P=0.041) among A. Grade 3 or 4 neutropenia was much common in pts in A than those in B (20.5% verse 4.9% , P=0.001), but was complicated by fever in only 3.6% of cases (4 pts) in A and in 2.9% of cases (3 pts) in B. No pts were dead or infectious due to neutropenia. There were similar rates of grade 3 or 4 transaminase elevation in the two groups. Vomitting and anorexia were much commoner with B. Conclusions: The L-OHP+RTX seems beneficial in recurrent and metastatic CRC, demonstrating better response rate and higher disease control rate with acceptable tolerability, maintenance of QoL and convenient administration schedule.

433 Background: Anti-VEGF agents and mTOR inhibitors are mainstay therapies in mRCC. Pre-clinical data suggests synergistic anti-tumor effect when combining these 2 classes. A previous phase I trial using sunitinib (S) 25 mg/d 4 wks on, 2 wks off, and temsirolimus (T) 15 mg/wk was stopped after 2 of the first 3 pts developed dose limiting toxicity (DLT). Methods: Pts with any subtype mRCC (PS 0-1) were eligible. Each cycle consisted of daily S for 14 days on, 7 days off, and weekly T. The continuous reassessment method (CRM) was used. The primary objective was to find the maximum tolerated doses (MTD) of S and T. The total planned accrual was 60 pts. Results: Accrual was stopped after 20 pts received study drugs. Median age was 63.5 years; 13 pts received prior targeted therapy, 7 pts were treatment naïve; median number of prior treatments 1 (range 0-6). Treatment cohorts (#pts, S, T, dose in mg): 2 (S12.5,T6), 1 (S25,T12.5), 1 (S12.5,T8), 8 (S12.5alt25,T9), 2 (S25,T6), 2 (S25alt37.5,T6), 2 (S37.5,T6), 2 (S37.5,T8). Dose reduction was required in 6 of 20 pts; the most common DLT was mucositis in 3 of 20 pts, followed by thrombocytopenia in 2 of 20 pts. The mean number of cycles for all pts was 6.6±5.36, with mean time on study 159±120 days. One pt experienced DLT in cycle 1 and received no study related imaging, 1 had a partial response, 16 pts had stable disease, and 2 pts had progressive disease (PD) as best response. A total of 21 grade 3/4 adverse events (AEs) attributed to drug occurred in 11 of 20 pts. Reasons for study discontinuation were PD in 12 pts, toxicity in 6 pts, and pt preference in 2 pts. There were no treatment related deaths. Conclusions: The MTD of S and T using the CRM were not reached due to premature trial closure. However, we believe S 37.5 mg/d, 2 wks on, 1 wk off, and T 8-10 mg weekly may well be close to MTD. Clinical trial information: NCT01122615.
