7105 Background: ABI-007 is a 130-nm albumin-bound form of paclitaxel. This study was designed to determine (1) the MTD and DLTs of ABI-007 in patients with stage IV chemotherapy-naive NSCLC and (2) the efficacy and safety of ABI-007 at the MTD. Methods: Eligibility requirement included ECOG PS 0–1, adequate organ function and sensory neuropathy ≤ grade 1. No prior chemotherapy for metastatic disease was allowed. Prior EGFR TKI therapy was allowed. ABI-007 was administered on days 1, 8, and 15 every 28 days (IV over 30 min. without premedication). In the phase I portion, 3 dose levels were studied (100, 125 and 150 mg/m2) and in the phase 2 portion, 40 patients were treated at the MTD. Results: 50 patients received ABI-007; the median age was 70 yo and 76% of patients were ≥ 65 yo. No DLTs were observed at the 100 and 125 mg/m2 dose level. However at the 150 mg/m2 dose level 2/6 patients had a DLT (febrile neutropenia and sensory neuropathy, respectively) during cycle 1 such that the MTD was exceeded. The 125 mg/m2 dose level was identified as the MTD and expanded to 40 patients in the phase 2 portion of this study. Toxicity and efficacy data is presented for the phase 2 portion. Ten patients (25%) had received prior neoadjuvant or adjuvant chemotherapy and 5 (13%) had received prior gefitinib or erlotinib. Sensory neuropathy was the most frequent toxicity with grade 2 and 3 toxicity occurring in 8% and 15% of patients. Grade 2 and 3 fatigue was observed in 8% and 13% of patients. Grade 3 and 4 neutropenia occurred in 10% and 3% of patients with no febrile neutropenia observed. Response was assessed by RECIST. One CR and 14 PRs were observed for an overall response rate of 15/40 (38%). The median survival was 10.3 months. Conclusions: The MTD for ABI-007 administered over 30 min. on days 1, 8, and 15 every 28 days was 125 mg/m2. No hypersensitivity reactions were observed and no premedication was given. In the phase 2 portion, a 38% response rate and 10.3 month survival was observed. Non-hematologic toxicities were primarily sensory neuropathy and fatigue. Myelosuppression was minimal and no febrile neutropenia was observed. Further development of ABI-007 in NSCLC is warranted based on the encouraging single agent activity observed in this study.

Abstract Introduction: Phase 2 single agent trials with lenalidomide and panobinostat in patients with relapsed or refractory HL have demonstrated overall response rates (ORR) of 19% (Fehniger et al., Blood 118:5119-5125, 2011) and 27% (Younes et al., JCO 30:2197-2203, 2012), respectively. We conducted a phase I/II trial to determine the dose limiting toxicity (DLT), maximum tolerated dose (MTD), and overall response rate (ORR) with combined lenalidomide and panobinostat in patients with relapsed HL. Methods: Patients with relapsed or refractory classical HL (cHL) or lymphocyte predominant HL (LP HL) after at least one prior therapy were eligible. Measurable disease > 1 cm, ejection fraction ≥ 45%, ECOG PS 0-2, QTc ≤ 450 msec, ANC ≥ 1200/mm3, platelets ≥ 100,000/mm3, AST/ALT ≤ 2.5 x the upper limit of normal (ULN), bilirubin ≤ 1.5 x ULN, and creatinine clearance 60 ≥ ml/min were also required. In the phase I trial, escalating doses of panobinostat (15 or 20 mg) days 1, 3, and 5 weekly were combined with lenalidomide 25 mg days 1-21 utilizing a 3+3 standard dose escalation design. DLT was defined during cycle 1 as grade 4 neutropenia or thrombocytopenia, grade 4 infection, grade 3 infection for > 7 days, treatment delays > 14 days, or other grade 3-4 non-hematologic toxicity. Twenty-eight days defined a cycle and patients could remain on therapy until disease progression. Response was assessed after cycles 2, 6, and every 4 cycles thereafter by International Harmonization Criteria (Cheson, JCO 25:579-586, 2007). Results: From Feb 2012 through June 2014, 22 patients (16 males) with cHL (n=21) and LP HL (n=1) and a median age of 45 (range 22-72) have been enrolled. Patients had received a median of 4 prior therapies (range 2-13), 9 patients were refractory to their most recent therapy, and 91% had stage III-IV disease at study entry. Ten patients had a prior autologous SCT, 1 patient had received prior allogeneic EBV-directed cytotoxic T-cells, 1 patient had a prior syngeneic transplant, and 1 patient had both prior autologous and allogeneic transplants. Eleven patients were enrolled in the phase 1 study at dose level (DL) 1 (25 mg lenalidomide + 15 mg panobinostat, n=6) and at DL 2 (25 mg lenalidomide + 20 mg panobinostat, n=5). Although there were no DLTs observed in cycle 1, 2 patients treated at DL 2 experienced grade 4 neutropenia and thrombocytopenia for > 14 days in cycle 2 and 3 of 5 patients were dose reduced to DL 1 in cycles 2 or 3. Therefore, DL 1 was expanded to 6 patients to ensure patient safety at this dose level and the phase 2 study was conducted at DL 1. Eleven patients have been treated in the phase 2 study. In all 22 patients, the median number of cycles completed on study was 4 (range 1-22). Grade 3-4 toxicities in all patients included neutropenia (59%), thrombocytopenia (41%), lymphopenia (27%), febrile neutropenia (27%), hypophosphatemia (9%), hypocalcemia (5%), QTc prolongation (5%), fatigue (5%), nausea/vomiting (5%), erythema nodosum (5%), transaminitis (5%), and unexplained altered mental status after administration of study medications (5%). Dose reductions were required in 10 patients (45%, 5 in the phase 2 study and 3 patients with multiple dose reductions) for febrile neutropenia, grade 3-4 neutropenia/thrombocytopenia, erythema nodosum, and transaminitis. Twenty-one patients have discontinued protocol therapy for PD (n=15), adverse events (n=5, including grade 4 neutropenia/thrombocytopenia or unexplained altered mental status after drug dosing), and to undergo elective CABG (n=1). ORR is 14% (2 CR and 1 PR) in 21 evaluable patients with complete responses in 1 patient with cHL and 1 patient with LP HL of 6 and 25 months duration, respectively. Conclusions: Combined panobinostat and lenalidomide appears to be well tolerated in patients with relapsed/refractory HL. Due to myelosuppression at higher doses, the recommended phase 2 dose of the combination is 25 mg lenalidomide days 1-21 with 15 mg panobinostat days 1, 3, and 5 weekly on a 28-day cycle. Accrual continues to the two-stage phase 2 trial, but based on preliminary data in the first 22 patients, the efficacy of combined lenalidomide and panobinostat appears similar to that previously reported with these drugs as single agents.

Abstract Background: Relapsed/refractory (r/r) Acute Myeloid Leukemia (AML) remains a therapeutic challenge. Although cytarabine arabinoside (AraC) is the most active drug, constituting the backbone of a majority of r/r regimens, the benchmark response to therapy remains a dismal 17 to 20% (Burnett, Wetzler et al. JCO, 2011.). The immunomodulatory drug lenalidomide (Len), is approved by the Food and Drug Administration for multiple myeloma and myelodysplasia and has demonstrated activity as a single agent in AML at doses as high as 50 mg for 21 days (d) of a 28 d cycle (Blum et al, JCO, 2010.). Based upon this activity profile we developed a phase I study to evaluate the safety and tolerability of Len in combination with AraC in patients with r/r AML. Methods: Eligible patients were older than 18 years(y), had r/r AML with an Eastern Cooperative Oncology Group performance status better than 2 and adequate renal and hepatic function. Patients were excluded for active CNS disease, uncontrolled infections, congestive heart failure, adrenal insufficiency, anti-cancer therapy within 14 d of enrollment, or prior exposure to Len. All enrolled patients had to practice appropriate contraception. Patients received AraC 1.5 g/m2/d over 3 hours on d 1-5 of a 28 day cycle, with a plan for standard 3+3 Len dose escalation. Initial patients received Len 25 mg on d 6-10 (n= 3), subsequent patients received doses between 25 and 10 mg (dose de-escalation) on d 6-26 with 2 d of rest prior to the next cycle. Following induction, patients who had residual AML (>5%) could receive a second identical course of therapy, provided they demonstrated an improvement in blast percentage relative to baseline. Patients who achieved CR received maintenance with Len 10 mg/d continuously. A 12 patient expanded cohort was enrolled at the maximum tolerated dose (MTD) to assess efficacy. Responses were assessed by International Working Group Criteria for AML (Cheson B et al. JCO, 2003.). Patient Characteristics: Fifty-one patients were consented and 45 were treated on study, 32 of these were evaluable for response, all patients were evaluated for toxicity. Approximately half the patients were female (20/45). The median age was 66 y (range 33-82) and median WBC 2.42x109/L (range 0.18-63.15). Four patients (8%) had an antecedent hematological disorder. By European LeukemiaNet criteria 2 patients (4%) had favorable risk disease, 8 (18%) were Int-1, 12(27%) were Int-2 and 11 (24%) were adverse risk; 12(27%) patients were not evaluable by ELN due to lack of karyotype or molecular data from diagnosis. Twelve patients had primary refractory AML. Results: The MTD for Len given on d 6-26 in combination with AraC at 1.5 g/m2/d x 5 d was 10 mg. Dose de-escalation from the starting dose of 25 mg on this schedule was required due to excess toxicity. The most commonly observed non-hematologic drug related adverse events seen on the study (all < grade 2 unless indicated) were nausea, increased liver function tests (>grade 3), rash (grade >3), hypokalemia (> grade 3) and fatigue. At the 25 mg dose level the dose limiting toxicity was rash, while patients enrolled at the 15 mg dose level experienced dose limiting elevation in LFTs, fatigue and bleeding. Five patients achieved a CR (16%), 5 demonstrated CRi (16%) and there were 3 hematological improvements (HI) for an overall response rate (CR+Cri+HI) of 41% (13/32). The median overall survival (OS) (95% confidence interval) for patients treated on study was 5.8 (2.5, 10.6) months and disease free survival was 3.4 (2.3, 6.2) months. Conclusions: Although prior interesting data support the activity of single agent high dose Len in r/r AML, our single institute phase I study of intermediate dose AraC followed by Len was associated with marked skin and other toxicities at the Len 25 mg dose level, precluding dose escalation to the historically more active 50 mg dose. The CR rate in this study was not dissimilar to previously reported responses with single agent or combination AraC based regimens. Issues of dose and schedule for this combination may have had a significant impact on the potential benefit for these two drugs in combination. Nevertheless, the overall low CR rate from this study does not suggest any superiority for this combination in comparison with the historical single agent response rate for intermediate dose AraC in r/r AML.

7125 Background: Single-agent chemotherapy is the standard treatment for elderly pts with advanced NSCLC, following the results of the ELVIS and MILES-1 trials. Some hints that infusing gemcitabine at a fixed dose rate of 10 mg/m2/minute can optimize its pharmacokinetics have been reported. A prospective phase 2 study was conducted to describe activity and toxicity of PCI-G. Methods: Advanced (stage IV or IIIb with supraclavear nodes or pleural effusion) NSCLC pts, aged >70, PS 0–1, were eligible. 51 patients were required according to a single-stage phase 2 design to have 90% confidence in estimating a 25% ±10% response rate. Response was assessed with RECIST; toxicity was coded with NCI-CTC. Results: From October 2002 to June 2003, 51 pts were enrolled. 26 pts (51%) were older than 75 years. Two complete and seven partial responses were observed, for an overall response rate of 17.6% (95% exact CI: 8–31). The median progression-free survival was 16 wks (95% CI: 11–21) and the median overall survival was 41 wks (95% CI: 28–51). Two toxic deaths were recorded (1 bronchial bleeding and 1 hepatic toxicity). Other relevant toxicities were (% of pts): grade 3–4 neutropenia (11.8%), grade 3 thrombocytopenia (5.9%), grade 3 pulmonary toxicity (3.9%) and grade 3 liver toxicity (3.9%); platelet transfusion, grade 3 anemia, RBC transfusion, non-neutropenic infection, and grade 4 neurotoxicity were all reported in one pt each. Conclusions: In this phase 2 prospective study dedicated to elderly pts with advanced NSCLC, PCI-G was not sufficiently active to warrant further investigation. No significant financial relationships to disclose.

Abstract Genomic aberrations in the cell cycle and PI3K pathway are commonly observed in recurrent childhood brain tumors. Dual inhibition of CDK4/6 (ribociclib) and mTOR (everolimus) has strong biologic rationale, non-overlapping single-agent toxicities, and adult clinical experience. The maximum tolerated dosage (MTD) and/or recommended phase two dose (RP2D) of ribociclib and everolimus was determined in the Phase I study and ribociclib concentrations were characterized in plasma and tumor in children undergoing neurosurgical procedures. Following resection, eligible patients were enrolled in the Phase I study according to a rolling 6 design and received ribociclib and everolimus once daily for 21 days and 28 days, respectively. Patients undergoing surgery received ribociclib at the pediatric RP2D (350 mg/m2/day) for 7–10 days pre-operatively. Pharmacokinetic samples were collected on both cohorts and analyzed in nine patients on phase I study. Sixteen eligible patients enrolled on phase I study (median age 10.3 years; range: 3.9–20.4) and 5 patients were enrolled on the surgical cohort (median age 11.4 years; range: 7.2–17.1). Six patients enrolled at dose level 1 without dose limiting toxicities (DLT). Two of the three patients at dose level 2 experienced DLT (grade 3 hypertension and grade 4 ALT). The most common grade 3/4 toxicities were lymphopenia, neutropenia, and leucopenia. Everolimus concentrations following administration of everolimus alone were lower than those following drug combination, suggesting an impact of ribociclib on everolimus pharmacokinetics. The MTD/RP2D of ribociclib and everolimus in recurrent CNS tumors is 120 mg/m2 and 1.2 mg/ m2 daily for 21 days and 28 days, respectively.

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 1874 Poster Board I-899 Lenalidomide (Revlimid®) and dexamethasone is an effective regimen in relapsed/refractory multiple myeloma (MM) patients (pts), with an overall response rate of 60.6% and median time to progression (TTP) of 13.4 months (Dimopoulos MA, et al, Leukemia 2009 Jul 23 [Epub ahead of print]). Oral cyclophosphamide and prednisone is an older regimen with excellent patient tolerance, and we sought to enhance the efficacy of lenalidomide by adding oral cyclophosphamide and prednisone in this phase I-II trial. The CPR regimen consisted of cyclophosphamide on days 1, 8 and 15; lenalidomide on days 1–21; and prednisone 100 mg every other day in a 28 day cycle. ASA 81 mg/day was given to all pts as DVT prophylaxis. Three dose levels were evaluated using a 3 by 3 dose escalation design. Between 11/2007–07/2009, 31 pts with relapsed/refractory MM who had not previously received lenalidomide were entered onto study. Median age was 61 (40–78) years and 61% were male. Immunoglobulin subtype was IgG in 19 pts (61%), IgA in 8 pts (26%) and light chain only in 4 pts (13%). Median number of prior regimens was 2 (1–5) and 28 pts had undergone previous ASCT, including double transplants in 6 pts. Prior therapy included thalidomide in 9 (29%) and bortezomib in 15 (48%). FISH cytogenetics were available in 13 pts; one had 13q deletion but none had t(4;14) or p53 deletion. At the time of protocol entry, median β 2-microglobulin level was 246 (92–767) nm/L, albumin 39 (34–48) g/L, creatinine 83 (50–126) μmol/L, platelet count 230 (75–337) × 109/L and ANC 2.5 (1.1–6.1) x 109/L. Protocol treatment is summarized in Table 1. Dose limiting toxicity was not observed during cycle 1 at any dose level. Grade 3–4 toxicities included thrombocytopenia in 5 pts (16%) and neutropenia in 9 pts (29%). These were managed with dose reduction and/or growth factor support. Four episodes of febrile neutropenia occurred. Other grade 3–4 non-hematologic toxicities included abdominal pain/bacteremia in 1 pt in cohort 1; hypokalemia in 1 pt in cohort 2; and DVT in 2 pts, dizziness in 2 pts and fatigue in 1 pt in cohort 3. Using the International uniform response criteria (Durie BG, et al, Leukemia 2006; 20:1467–1473), the best response was documented at a median of 6 (1–5) cycles and included the following: dose level 1 (1 CR, 2 PR); dose level 2 (1 VGPR, 2 PR); dose level 3 (5 CR, 9 VGPR, 9 PR, 1 MR and 1 stable disease). At a median follow-up (F/U) of 12 (8–21) months, 20 pts remain on study, 2 have withdrawn and 9 pts have progressed at a median of 9 (4–13) months; only 1 one has died (due to MM). We conclude: 1) the combination of full doses of the agents in CPR can be given in a 28 day cycle with minimal toxicity; 2) the overall response rate (CR + VGPR + PR) in 31 pts to date is 93%; 3) at a median F/U of 1 year, only 9 pts (29%) have progressed; 4) longer follow-up is required to assess the TTP and survival of the CPR regimen.

Abstract Abstract 4765 BACKGROUND Gemcitabine induces a 20% response as single agent therapy in patients with relapsed or refractory NHL. We report phase I findings of gemcitabine in combination with standard CHOP chemotherapy with G-CSF support for intermediate grade NHL. The protocol was modified during enrollment to include rituximab in CD 20+ lymphomas. METHODS Patients received CHOP plus gemcitabine at 500 mg/m2 (Cohort 1) or 750 mg/m2 (Cohort 2) on days 1,4 of each 21 day cycle. Accrual was suspended once each cohort was filled. Dose escalation occurred after all patients in the cohort were determined to not have a dose limiting toxicity. RESULTS Between 4/02 and 5/04 10 patients were enrolled and completed the study treatment (6 in cohort 1, 4 in cohort 2). In Cohort 1, grade 3 toxicities included neutropenia, anemia, neuropathy, and constipation. Grade 4 toxicities were febrile neutropenia, and thrombocytopenia. In Cohort 2, grade 3 toxicities included neutropenia, thrombocytopenia, mucositis, anemia and intestinal obstruction. Grade 4 toxicities included febrile neutropenia, neutropenia, and thrombocytopenia. One patient developed MDS 36 months after chemotherapy. Three of four patients in Cohort 2 developed dose limiting toxicities (mucositis and thrombocytopenia) requiring dose reduction of gemcitabine after cycle 1. Overall, the survival rate at 2.5 years was 71%. CONCLUSIONS This Phase I trial concludes that gemcitabine 500mg/m2 on days 1 and 4 of each 21 day cycle is the maximum tolerated dose when combined with standard CHOP chemotherapy with G-CSF support for intermediate grade NHL. Response rates are encouraging for this novel chemotherapeutic regimen. Disclosures: Off Label Use: Gemcitabine was added to standard CHOP chemotherapy in this trial.. Sikov:Eli Lilly: Honoraria.

13168 Background: Triapine (T) is a novel ribonucleotide reductase inhibitor, affecting the M2 subunit. It has in vitro and in vivo antitumor activity. Hematologic toxicity was dose limiting in single agent phase I trials. Triapine potentiates the activity of DNA damaging agents such as doxorubicin (D), with synergy demonstrated in vivo. Methods: D was administered on day 1 and T was administered on days 1–4 of a 21-day cycle. Patients enrolled in cohorts of three, beginning at D60 mg/m2 and T25 mg/m2. Dose limiting toxicity was defined as grade 3 or 4 leukopenia or thrombocytopenia lasting 7 days, febrile neutropenia or grade 3 or 4 non-hematologic toxicity. Results: Fourteen patients have enrolled in four dose cohorts, receiving 23 courses. At dose level 2 (D60 mg/m2, T45 mg/m2), two patients experienced DLT (febrile neutropenia, grade 4 thrombocytopenia). An additional 3 patients enrolled at dose level one without initial toxicity. Enrollment then resumed at dose level 2a with a decreased dose of doxorubicin (D45 mg/m2, T45 mg/m2). Two patients enrolled on this level had DLT. Enrollment was planned to resume at dose level 1 (D60 mg/m2, T25 mg/m2); however, the sixth patient enrolled to this cohort developed grade 5 heart failure (ejection fraction 20%, pretreatment EF 62%) after the second course. Enrollment has begun at doses of D45 mg/m2 and T25 mg/m2. Hematologic toxicity has predominated, with 52% of courses having grade 3 or 4 neutropenia. Non-hematologic toxicity included grade 2 fatigue in 17% of courses and 1 episode of grade 5 heart failure. Although no objective antitumor responses have been seen, 1 patient with metastatic melanoma had stable disease through 6 cycles of treatment. Another patient with previously rapidly progressive metastatic melanoma had stable disease for over 2 months of treatment. Conclusions: The combination of triapine and doxorubicin appears to have increased toxicity. Enrollment continues. [Table: see text]

e13531 Background: B is a DNA minor groove binding (MGB) agent with single agent cytotoxic activity. B has shown synergy with BV and I. The combinations were studied using a “complete” phase I design. Methods: The primary objective was to determine the maximally tolerated dose (MTD) and dose limiting toxicities (DLT) of B+BV and B+I. For B+BV cohort 1 both drugs were infused on day 1 of a 21 day cycle. BV was dosed at 15mg/kg, B was dosed at 6 mg/m2. For cohort 2, the BV dose was unchanged, and B dose reduced to 4 mg/m2. For B+I cohort 1 both drugs were also infused on cycle day 1. I was dosed at 200 mg/m2 with B at 4 mg/m2. For cohort 2, I was reduced to 125 mg/m2 and B reduced to 2 mg/m2. Cycle 1 DLT was defined: grade 4 neutropenia lasting ≥ 5 days, grade 3 or higher febrile neutropenia, grade 4 thrombocytopenia or grade 3 or 4 thrombocytopenia with bleeding, grade 3 or higher diarrhea, nausea or vomiting despite optimal management, grade 3 or higher for all other non-hematologic toxicities. For pts receiving BV, grade 2 or higher proteinuria. Eligible pts had treatment refractory metastatic/unresectable solid tumors, acceptable performance status, and adequate hematologic parameters and organ function. Results: 19 pts were enrolled. 11 pts received B+BV and 8 received B+I. Median age was 58 years. For B+BV 5 patients were treated in cohort 1, 6 in cohort 2. For B+I, 2 patients were treated in cohort 1, 6 in cohort 2. The MTD has not been defined for either treatment combination. In the current preliminary dataset 18/19 pts (93.3%) experienced one or more adverse events (AEs). In the B+BV group, grade 4 neutropenia was reported in 2/11 patients, both in cohort 1, and grade 3 neutropenia in one additional patient, also in cohort 1. In the B+I group, grade 4 AEs included neutropenia (DLT), febrile neutropenia (DLT), severe abdominal pain, and thrombocytopenia. Of the evaluable pts, no complete or partial responses were seen. For B+BV 5/11 pts have received 4 or more cycles, and for B+I 2/8. Conclusions: The combination of B+BV and B+I show manageable toxicity in advanced solid tumors at the doses reached in cohort 2. Additional data will be provided at the time of presentation. [Table: see text]

Cyp3a Inhibitor

e15116 Background: Cabazitaxel (Cbz) is a novel taxane with in vivo efficacy in taxane-sensitive and -resistant tumors. Therapeutic synergism of Cbz/cisplatin (Cis) has been shown in tumor-bearing mice. Since Cbz is primarily metabolized by CYP3A, drug interactions may occur with modulators of CYP3A. Methods: The primary objective of part 1 of this phase I study (NCT00925743) was to determine the maximum tolerated dose (MTD) and dose-limiting toxicities (DLTs) of Cbz/Cis. Secondary objectives included safety, pharmacokinetics (PK) and efficacy. The objective of part 2 was to assess efficacy at the MTD. The effect of the antiemetic aprepitant (a moderate CYP3A inhibitor) on the PK of Cbz was also examined. Eligible patients (pts) had ECOG PS ≤ 1 and confirmed metastatic or unresectable solid tumors for which Cis therapy was considered appropriate. A 3 + 3 dose escalation at a starting dose (level 0) of 20/75 mg/m2 (Cbz/Cis), administered IV Q3W, was used. The MTD was the highest dose at which 0/3 or ≤ 1/6 pts experienced a DLT in Cycle 1. Results: Pts (n = 25; 10 in part 1; 15 in part 2) with a median age of 56 yrs were enrolled. The most frequent primary tumors were lung (n = 4), prostate, ovary and pancreas (each n = 2). Of 6 evaluable pts, 2 had a DLT at dose level 0 (Grade 3 acute renal failure; febrile neutropenia). The MTD was 15/75 mg/m2 as no DLTs were observed; 18 pts were treated at the MTD and 60 cycles were administered (median = 3; range 1–8). The most frequent non-hematologic treatment-related adverse events (all grades/grade 3–4) were nausea (78%/22%), vomiting (72%/11%), fatigue (61%/17%), anorexia (67%/11%) and diarrhea (44%/0%). Incidence of grade 3–4 neutropenia was 78%; 1 pt had febrile neutropenia. The combined PK profile of Cbz/Cis did not appear to differ vs those of the single agents. The ratio of Cbz clearance with vs without aprepitant co-administration was 0.81 (90% CI 0.36–1.85). Stable disease was seen in 11 pts; 1 pt (prostate carcinoma) had an unconfirmed partial response. Conclusions: The MTD of Cbz/Cis was 15/75 mg/m2. The combination had a manageable safety profile consistent with a platinum/taxane combination. No PK interactions between Cis and Cbz were seen; aprepitant did not appear to alter the PK of Cbz.
