12012 Background: The combination of D and T has many potential applications, particularly in breast and ovarian cancers. A phase 3 trial is examining D + T versus T in first-line metastatic breast cancer ( NCT00091442 ). D has better tumor localization and penetration in solid tumors than conventional doxorubicin. In previous studies, the maximum tolerated dose (MTD) of the combination was identified as D 30 mg/m2 and T 75 mg/m2 q4 weeks (wks), with a recommended dose and schedule of D 30 mg/m2 and T 60 mg/m2 q3wks without G-CSF. We conducted a phase I study to determine the MTD of D with weekly T. Our hypothesis was that the lower incidence of myelosuppression with weekly T would allow for higher doses of both drugs. Methods: There were 2 schedules. Arm A: D q4wks starting at 25 mg/m2 with weekly T for 3 wks starting at 30 mg/m2. Arm B: D q2wks starting at 15 mg/m2 with weekly T for 3 wks starting at 30 mg/m2. One cycle was 28 days. Standard 3+3 design was used with MTD defined as the highest dose level causing dose limiting toxicity (DLT) in ≥ 2/6 patients (pts). Results: 32 pts were treated; 13 females, 19 males, median age of 60 years. Median number of cycles administered was 2 (1–13) with a median follow-up of 11.5 months. Tumor types included lung (16%), thyroid (9%), esophagus (9%), nasopharynx, breast, colorectal, stomach and kidney (6% each). Arm A (13 pts) was closed after 2/7 evaluable pts at dose level 2 (D 33mg/m2; T 30 mg/m2) experienced DLT in the form of grade 3 stomatitis. The most common grade 3/4 toxicities were neutropenia (3/13), stomatitis (3/13) and fatigue (3/13). Arm B accrued 19 pts. The trial was closed at the highest planned dose in Arm B (D 20mg/m2 q2wks and T 35 mg/m2 weekly) with only 1/6 evaluable pts experiencing DLT in the form of grade 4 fatigue and weakness. The most common grade 3/4 toxicities in Arm B included neutropenia (5/19 pts), fatigue (5/19 pts) and stomatitis (2/19 pts). There was no grade 3/4 hand-foot syndrome or cardiotoxicity. 2 partial responses were observed in nasopharyngeal and salivary gland carcinomas, with 13 pts achieving stable disease. Conclusions: The combination of D q2 wks and T weekly for 3/4 wks is well tolerated and results in a higher dose intensity of both drugs than in previously evaluated regimens. [Table: see text]

Abstract Background: Despite improvements in overall survival (OS) and progression free survival (PFS), the prognosis of patients with relapsed/refractory multiple myeloma (RRMM) remains poor. Carfilzomib (CFZ), a second generation proteasome inhibitor, is active as a single-agent or in combination with lenalidomide and/or dexamethasone (DEX) in RRMM. Pegylated liposomal doxorubicin (PLD) combined with bortezomib has been shown to prolong PFS and OS and is FDA approved as combination therapy in MM. We investigated the combination of CFZ with PLD in RRMM in a Phase I study. Objective: To determine the maximum tolerated dose (MTD) of CFZ combined with PLD. Patient/Methods: Patients with RRMM after ≥ 1 lines of therapy, with measureable disease, and good performance status, organ function and hematological reserve were eligible. Prior CFZ or PLD/doxorubicin exposure was not exclusionary. CFZ was given on days 1, 2, 8, 9, 15 and 16 at escalating doses of 27-56mg/m2 and PLD was given on day 8 in 28 day cycles at a dose of 30mg/m2. All dose levels included a lead-in dose of 20mg/m2 of CFZ on days 1 and 2 of cycle 1. Following 6 cycles of combination therapy, PLD was discontinued and patients were treated with maintenance CFZ (once weekly). Dose escalation was performed using a 3+3 design; MTD was defined as the highest dose level where dose limiting toxicity (DLT) occurred in less than 2 of 6 patients. Disease response was determined using International Myeloma Working Group (IMWG) criteria. Results: 16 patients were enrolled from May 2012-March 2014. Median age was 66 years (range 53-79) and 11 were female. Seven patients were ISS stage 3, 9 were stage 1. 3 patients had > 50% plasma cells present on bone marrow aspirate, 8 had < 20%. By mSMART criteria, 2 patients were high-risk, 2 were intermediate-risk, and 12 were standard-risk. Most patients were IgG Kappa subtype (12); while 3 patients had Kappa light chain subtype, and 1 had IgG Lambda subtype. Median number of prior therapies was 3 (range 1-12). Median time from diagnosis to start of protocol was 42 months (range 9-236). 100% had prior exposure to lenalidomide; 87.5% had prior exposure to bortezomib; 75% had undergone autologous transplantation; 6% had prior PLD or doxorubicin exposure; and 6% had prior CFZ exposure. No DLTs were observed in any cohort. Two patients were unable to complete the first cycle of treatment due to early progressive disease, and were replaced. Grade 3/4 non-hematologic adverse events were rare, but included: UTIs (3), sepsis (2), pneumonitis (2), dyspnea (2), syncope (1), pleural effusion (1). Grade 3/4 hematologic AEs were limited to: anemia (7), thrombocytopenia (4), neutropenia (5), lymphopenia (4), and hemolysis (2). Most of the neutropenia (60%) and thrombocytopenia (75%) occurred in the 56mg/m2 cohort. The median number of cycles completed was 3.5 (range <1-13). Disease progression caused discontinuation in 10 patients. Adverse events were the reason for 2; one patient had dyspnea after 2 cycles, one patient had hand-foot syndrome after 3 cycles. Four patients were on treatment at time of submission. 56% of patients had a partial response or better, including 80% treated at the maximum dose level. The median duration of response was 6.9 months. Individual patient responses are summarized in Table 1. Conclusion: Co-administration of CFZ and PLD is well tolerated and an MTD was not reached despite utilizing the approved single agent doses. Recommended dosage for further studies is: CFZ 56mg/m2 and PLD 30mg/m2. Subsequent phase I dose escalation of a 3 drug regimen CDD (CFZ-PLD-DEX) is ongoing at abstract submission and will be reported at the meeting.

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 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.

Abstract Phase I and II clinical studies demonstrated activity of Clofarabine in acute leukemias. In previous studies we have investigated clofarabine, plus ara-C combinations and reported a CR rate of 24% in relapsed AML and 52% in previously untreated AML ≥ 50 years (yrs) with acceptable toxicity profile. Anthracyclines are active in AML. To explore clofarabine further in AML combinations we conducted a phase I study of clofarabine with idarubicin with or without ara-C in pts with relapsed AML, MDS, and CML. Considered as dose-limiting toxicities (DLT) are ≥ grade 3 drug-related toxicities. Maximum tolerated dose (MTD) will be determined by “3+3” dose escalation scheme. On the clofarabine (C)/idarubicin (I) combination (CI), 9 AML pts are enrolled (2 primary refractory, 7 first relapse). Median age: 58 yrs (range 24–71). Median first remission duration (CRD1): 3.1 mos. (0–7.6). For the first dose level, C was given at 22.5mg/m2 i.v. daily x 5d and I at 12mg/m2 i.v. daily x 3d. Among the first 6 pts, 2 ≥ gr. 3 toxicities (diarrhea, rash, ↑ bili) occurred necessitating dose de-escalation of C to 15mg/m2 i.v. daily x 5 and I 8mg/m2 i.v. daily x 3. Among 3 pts, 1 ≥ gr.3 toxicity (↑ bili) was observed. No responses occurred. On the CI + ara-C arm (CIA), 7 AML pts are enrolled (1 primary refractory, 6 first relapse). Median age: 58 yrs. (24–78). Median CRD1: 11.2 mos. (0–13.1). First dose level: C 22.5mg/m2 i.v. daily x 5d, I 8mg/m2 i.v. daily x 3d, A 1g/m2 i.v. daily x 5d. Of 3 pts, 2 developed ≥ gr.3 toxicities (↑ bili, diarrhea) leading to the following de-escalation: C 15mg/m2 i.v. daily x 5d, I 6mg/m2 i.v. daily x 3d, A 0.75g/m2 i.v. daily x 5d. Of 4 pts (1 ≥ gr. 3 rash, ↑ bili), 3 pts achieved CR. The phase I study is ongoing until determination of DLT and MTD for each arm. Our preliminary results indicate clinical activity of CIA even at the low dose level.

Abstract Background: Epigenetic silencing of genes has been documented in AML. This phase I trial evaluates the safety, tolerability, and maximum tolerated dose (MTD) of two schedules of administration of the hypomethylating agent decitabine in combination with the pan-selective histone deacetylase inhibitor vorinostat. Methods: Patients receive escalating doses of oral vorinostat administered either sequentially [100 mg bid (n=4), 200 mg bid (n=4), or 200 mg tid (n=8) Days 6–21] or concurrently [100 mg (n=3) or 200 mg (n=6) bid Days 1–21 or 200 mg tid (n=2) Days 1–14] with decitabine (20 mg/m2/d IV Days 1–5) every 28 days. Results: Twenty-seven patients with AML have been treated. Median age was 67 years (range, 32–82 years). Median ECOG status 1 (range, 0 to 2). Eighteen patients (67%) had received prior therapy (median, 1 regimen; range, 0 to 4 regimens); 3 had received a prior allogeneic stem cell transplant. A total of 85 cycles have been administered, with a median of 2 cycles (range, 1 to 13 cycles); 10 patients (37%) have received 3 or more cycles of therapy. One of 7 patients treated at dose level 3 of the sequential schedule developed dose-limiting toxicities (DLT), consisting of grade 3 fatigue, weakness, and mucositis. Therefore, the MTD was not reached in the 3 planned dose levels of the sequential schedule. One DLT (grade 3 fatigue) occurred in 6 patients treated at dose level 2 of the concurrent schedule. Most common drug-related non-hematological toxicities of any grade (all CTCAE grades 1 or 2) were nausea (71%), fatigue (54%), diarrhea (54%), vomiting (42%), anorexia (25%), constipation (13%), abdominal pain (13%), dehydration (13%), and headache (13%). No other non-hematological grade 3 or 4 toxicities were observed. Of the 25 evaluable patients, one patient achieved an incomplete CR (without neutrophil recovery), one a morphologic leukemia-free state (without blood count recovery), and three partial remissions (1 achieved red cell transfusion independency and a second normalization of platelet counts). Seven of these patients remain on study for 2.7 to 13.5+ months. Correlative studies examining histone acetylation and gene promoter methylation in leukemic cells at baseline and after treatment, as well as plasma pharmacokinetic levels for both decitabine and vorinostat are being evaluated. Conclusions: The combination of decitabine and vorinostat is safe, well-tolerated, and has clinical activity in patients with AML. Enrollment is ongoing.

Abstract Oral cyclophosphamide and prednisone is a convenient regimen in relapsed and refractory multiple myeloma (MM), with a partial response (PR) rate of 40% and median progression-free survival of 19 months in our retrospective analysis of patients in first or second relapse after autologous stem cell transplantation (ASCT) (Trieu Y, et al, Mayo Clin Proc2005; 80: 1582). We sought to enhance the efficacy of this regimen by adding oral lenalidomide (Revlimid®), a potent anti-myeloma agent, in a 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 patients (pts) as prophylaxis for DVT. Three dose levels were evaluated using a 3 by 3 dose escalation design. Between 11/2007–07/2008, 15 pts with relapsed/refractory MM were entered onto study. Median age was 60 (45–78) years and 60% were male. Immunoglobulin subtype was IgGκ:λ in 10:1; IgA κ:λ in 2:1 and κ light chain in 1. Median number of prior regimens was 2 (1–3) and 14 had undergone previous ASCT, including double transplants in 2 pts. Prior therapy also included thalidomide in 3 (20%) and bortezomib in 6 (40%). FISH cytogenetics were available in 9, but none had 13q deletion, t(4;14) or p53 deletion. At the time of protocol entry, median β2-microglobulin level was 222 (92–325) nm/L, albumin 38 (35–46) g/L, creatinine 78 (50–100) μmol/L, platelet count 230 (93–318) x 109/L and ANC 2.5 (1.9–9.0) x 109/L. Protocol treatment is summarized in Table 1. Dose level N Cyclophosphamide dose (mg/m2) Lenalidomide dose (mg) Prednisone dose (mg) Median # cycles given 1 3 150 15 100 9 2 3 150 25 100 6 3 6 300 25 100 4 3 (expanded) 3 300 25 100 1 Dose limiting toxicity was not observed during cycle 1 at any of the dose levels and the maximum tolerated dose of this regimen has not yet been reached at the highest dose level planned; all pts remain on active therapy. Grade 3/4 thrombocytopenia was seen in 1 pt (cohort 2) and neutropenia in 4 pts (1 in cohort 1, 1 in cohort 2 and 2 in cohort 3) and were managed with dose reduction and/or growth factor support. No episodes of febrile neutropenia occurred in any pt. Only 1 pt experienced varicella zoster; routine antiviral prophylaxis was not used. Other grade 3/4 non-hematologic toxicities were uncommon and included abdominal pain/bacteremia in 1 pt in cohort 1, hypokalemia in 1 pt in cohort 2, and DVT in 1 pt in cohort 3. Mild grade 1/2 constipation (47%), muscle cramps (33%) and fatigue (33%) were also noted. To date, best response includes the following: dose level 1 (1 near complete remission [nCR], 2 PR); dose level 2 (3 PR); dose level 3 (4 PR, 2 minimal response [MR]); expanded cohort 3 (1 MR, 2 too early). 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 (nCR + PR + MR) in 13 evaluable pts to date is 87%; 3) no pts have progressed in this preliminary analysis; 4) longer follow-up is required to assess the long-term efficacy of this regimen.

12008 Background: Taxanes have demonstrated activity across a broad range of cancers, but resistance remains an issue. TPI 287 is a third generation taxane designed to overcome issues of resistance secondary to mdr and mutant tubulin. The purpose of this Phase I study was to determine the maximum tolerated dose and pharmacokinetics of IV TPI 287. Methods: Phase I study: TPI 287 is administered IV on days 1, 8, 15 of a 28 day cycle (Q7D) with at least 3 patients treated per dose escalation, in a typical phase I design. Dosing began at 7 mg/m2 and has advanced to the fifth cohort of patients, who are being treated at a dose of 85 mg/m2. Tumor response is assessed after every second cycle via imaging and tumor measurements. Samples are collected for PK analysis and circulating tumor cell (CTC) quantitation. Results: Sixteen pts have been enrolled (9 males, median years = 60.11; 7 females, median years = 50.71: median number of previous chemotherapies = 4). Diagnoses included colorectal (4), prostate (3), breast, kidney, cervical, brain, lung, osteosarcoma, basal cell, endometrial, ovarian cancers. Of 16 pts, 8 and 5 have completed 1, 2 cycles, respectively. Only one drug related grade 3 adverse event (hypersensitivity reaction) occurred, at 14 mg/m2. No other reported toxicities are related to TPI 287. PK and CTC studies are ongoing. Conclusions: These initial results show that TPI 287 is well tolerated at a dose up to 56 mg/m2 administered Q7D, and dose escalation continues. [Table: see text]

1066 Background: Inhibition of mTOR with everolimus (E) may improve efficacy in combination with docetaxel (D), but both drugs are metabolized by CYP3A4, thus a pharmacokinetic (PK) interaction may also exist. Methods: 15 patients (pts) with MBC were treated with docetaxel and everolimus using the continuous reassessment method (CRM) to determine maximum tolerated dose (MTD). Docetaxel doses were 40–75 mg/m2 IV on day 1 of a 21 day cycle. Everolimus doses were 20–50 mg PO on days 1 and 8 of a 21 day cycle (except cycle 2, where only day 8 was given to allow single agent PK analyses of both drugs). Response was measured every 2 cycles using RECIST. Results: Median age= 58 years and 77% of pts had >2 prior chemotherapies for MBC. Initially 2 of 2 pts treated (D= 75 mg/m2, E= 30 mg) developed DLT (neutropenic fever/infection), prompting a mandatory PK evaluation for all pts enrolled in subsequent cohorts. A second cohort of 3 patients (D=60 mg/m2, E=20mg) had no DLT, but no pts received day 8 of E due to grade 3–4 neutropenia. PK analyses demonstrated a 42% lowered (-42%) D clearance at the 60 mg/m2 in the presence of E (n=1). Subsequent cohorts were accrued at D=40 mg/m2 with escalating doses of E (Table). For the entire group, an 18% decrease (-18%) in D clearance was observed when D was administered concomitantly with E. High interpatient variability of D clearance was observed (range +16% to -135%). No pts had CR/PR, but 6 had SD>4 cycles and 2 had SD=8 cycles. Conclusions: Weekly everolimus appears to cause widely variable and unpredictable changes in docetaxel clearance making this combination unfeasible. [Table: see text] No significant financial relationships to disclose.

7569 Background: We conducted a phase I/II study of combination chemotherapy with nedaplatin (CDGP) and amrubicin (Amr) for patients with untreated, advanced non small-cell lung cancer (NSCLC). Methods: Eligible patients were having adequate organ function and PS of 0-1. CDGP was given on day 1 and amrubicin on days 1, 2 and 3. The treatment was repeated every 3 weeks. We fixed the dose of CDGP as 100 mg/m2, and escalated the dose of amrubicin from a starting dose of 25 mg/m2 by 5mg/m2 per each levels until the maximum tolerated dose (MTD). The MTD was defined as the dose level at which at least two of three or two of six patients experienced a dose-limiting toxicity (DLT). Results: Between June 2009 and May 2011, 36 patients were enrolled. In the phase I study, two DLTs occurred in six patients at level 2; dose level 1 was therefore recommended (25 mg/m2 Amr, 100mg/m2 CDGP). DLTs included cerebral infarction and grade 4 thrombocytopenia. In the phase II study, including phase I study, a total of 36 patients were enrolled and 132 cycles of chemotherapy were conducted. Grade 3 or 4 neutropenia, grade 3 anemia and grade 3 or 4 thrombocytopenia occurred in 75%, 16.6% and 19.4% in all cycles, respectively. Febrile neutropenia occurred in 4cycles (3%) but all of them were controllable. Eighteen patients achieved a partial response and the overall response rate was 51.4%.

164 Background: Angiogenesis and suboptimal antitumor immune response are important in the progression of CRPC. Both LEN and metronomic CTX have known anti-angiogenic and immunomodulatory activities. A phase I study of a novel combination of metronomic CTX with LEN in patients with CRPC who have failed prior docetaxel therapy was initiated to assess safety and effects on potential biomarkers. Methods: CTX was given 50 mg PO QD(day 1-28) and LEN 10-25 mg PO QD(day 1-21) on a 28 day cycle. Dose limiting toxicity was defined as any treatment-related grade 4 hematologic event or grade 3 / 4 non-hematologic event during cycles one. Quantification of circulating tumor cells (CTC), plasma cytokines, analgesic consumption and quality of life assessments were performed. Measurement of Treg and MDSCs were performed in some patients. Results: 17 patients with CRPC have been enrolled in L0-4; all patients are evaluable for toxicity. Patient characteristics include: ECOG performance status 0/1= 4/13; median age=77 (range 50–86); median PSA=36.7 (range 1.36–2287). Dose level 1 (CTX 50 mg/d, LEN 10 mg/d) was expanded to 6 patients after one out of three initial patients was removed from the study for Gr 3 gastrointestinal bleeding (in cycle 1). Dose level 1 (CTX 25 mg/d, LEN 10 mg/d) had no DLT’s. The maximum tolerated dose has not yet been reached. Other Grade 3/4 toxicities observed after cycle 1 included grade 3 pain (N=1), grade 3 neutropenia (N=4), grade 3 thrombocytopenia (N=2), grade 4 neutropenia (N=2). Most frequent grade 1 and 2 toxicities included anemia, fatigue, neutropenia, and hypocalcemia. Overall, 9 of 14 patients (64%) have experienced a reduction in PSA. One patient had partial response after one cycle. Stable disease was documented in 5 of 14 (36%) evaluable patients. Two inflammatory cytokines, IL-6 (N = 19; r = 0.64; p = 0.0035) and IL-8 (N = 9; r = 0.86; p = 0.0028), were found to significantly correlated with PSA. Conclusions: The combination of metronomic CTX and LEN can be safely administered. Preliminary clinical activity was observed in this heavily-pretreated patient population. Enrollment to this study continues and clinical and biomarker studies are ongoing.
