`A phase II study of E7070 in patients with metastatic, recurrent, or refractory head

`E7070 is a synthetic sulfonamide that targets the G1 phase of the cell cycle. It
`causes depletion of cyclin E, upregulation of p53 and p21Waf1lCip1, as well as
`inhibition of cdk2 phosphorylation. All of these events contribute to hypophos-
`phorylation of the retinoblastoma (Rb) protein and cause a blockade in the G1/S
`transition. We conducted a phase II study of E7070 in patients with noncurable
`HNSCC. Patients received 700 mglm2 over one hour every 3 weeks. Fifteen
`patients were treated with a median age of 59 years. A total of 39 cycles of
`E7070 were delivered, median 2.6 per patient. Six patients had progressive
`disease (PD) after 2 cycles and 3 patients had PD after one cycle. Five patients
`showed stable disease (SD) after 2 cycles and went on to receive 1 (2 patients), 2
`(2 patients) and 3 additional cycles (1 patients), respectively, before showing
`PD. One patient remains on study and has received 5 cycles with SD. A fine
`needle aspirate (FNA) was obtained from 5 patients prior to treatment and within
`24 hrs after the completion of the first 3—hr infusion to determine whether the
`phosphorylation of Rb was modulated in tumor cells following drug exposure.
`Aspirates were subjected to immunohistochemistry with phospho-specific anti-Rb
`antibodies directed at the T821, S795 and S807l811cdk2- and cdk4-specific
`phosphorylation sites.Among the 3 patients with informative samples, results
`were as follows: E7070 demonstrated very limited activity against SCCHN.How-

`Phase I study of the proteasome inhibitor burtezumib and pegylated liposomal
`doxorubicin in patients with refractory hematologic malignancies. R. Z.

`Pharmaceuticals, lnc., Cambridge, MA
`The proteasome is involved in intracellular protein degradation, and is a
`novel target for therapy of hematologic malignancies. Proteasome inhibi-
`tors also block activation of several survival pathways, including NF—KB and
`p44l42-MAPK, that may limit the effectiveness of anthracyclines, suggest-
`ing such combinations might have enhanced anti-tumor efficacy. We
`sought
`to evaluate the maximum tolerated dose(MTD), dose limiting
`toxicity(DLT), pharmacokinetics, and pharmacodynamics of the protea-
`some inhibitor bortezomib(B;Velcade) and pegylated,
`liposomal doxoru-
`bicin(D;Doxil) in patients(pts) with hematologic malignancies. B was given
`as an intravenous bolus at 0.90-1.30-mglmz on days-1, -4, -8, and -11 of
`a 3-week cycle, and D on day—4 at 3O~mg/m2. The MTD was defined based
`on cycle-1, while responses were evaluated every 2 cycles. 19 pts have
`been treated, and have included 14 multiple myeloma(M M) pts. A mean of
`4.4 cycles (range 1-10) has been administered, with 15 pts evaluable for
`toxicity. At 0.90-mg/m2 a pt with Crohns disease had grade(g)-3 diarrhea,
`hypotension, confusion and syncope, but no other DLTs were noted at this
`or other
`levels, and the MTD has yet
`to be defined. All other non-
`hematologic drug-related toxicities during cycle-1 have been g—1l2 in
`intensity. G-3/4 toxicities in later cycles included fatigue, palmar plantar
`erythrodysesthesia, cytopenias, and neuropathy. Of 10 evaluable MM pts
`complete responses(CR) have been observed in 3, near-CR in 1, partial
`responses(PR) in 3, 1 pt each had a minor response or stable disease, while
`one progressed. Five of these pts, including two of the CR3, had disease
`that previously progressed, or did not respond to anthracycline-based
`therapy, and five are continuing treatment. Also, one pt with relapsed acute
`myeloid leukemia had a PR. Early results from this study suggest that BD
`may be well—tolerated and active in patients with multiple myeloma, and
`possibly other hematologic malignancies. Accrual is continuing to define
`the MTD and DLT.

`A phase I study of the oral mTOR inhibitor RAD001 as monotherapy to identify
`the optimal biologically effective dose using toxicity, pharmacokinetic (PK)
`and pharmacodynamic (PD) endpoints in patients with solid tumours.A_.

`
`RAD001, a novel derivative of rapamycin, interacts with the mTOR protein
`kinase to inhibit downstream signalling proteins crucial
`to cell cycle
`progression, Pre-clinical
`in vitro and in vivo studies have shown dose
`dependent inhibition of tumour growth and reduced tumour vascularity, as
`well as the ability to potentiate the activity of a number of cytotoxics
`including paclitaxel and gemcitablne. Methods: This phase I dose escala-
`tion study was performed to identify the optimal biologically effective dose
`based on toxicity, PK and PD assessments using the biomarker p70 S6
`kinase 1 (S6K1) activity in peripheral blood mononuclear cells (PBMCs).
`indication of activity was also sought using conventional and PET imaging.
`Treatment with RAD001 was given orally, once weekly. Results: Cohorts of
`4 patients were treated at each of 4 dose levels: 5, 10, 20 and 30mg.
`(7M:9F; Median age 60y, Range 32-75 y) RAD001 was well tolerated with
`only mild degrees (Gr 1/2) of anorexia, fatigue, rash, mucositis, headache,
`hyperlipidemia and gastrointestinal disturbance. PK results are consistent
`with prior experience (renal transplant and healthy subject studies): AUC
`increasing in proportion to dose, a plateau in Cmax occurring at doses
`220mg and a terminal t,,2 of 26-38 hours. 4 patients (hepatocellular
`10mg; fibrosarcoma 10mg; NSCLC x 2, 30mg) have stable disease >16
`weeks. A responding patient with NSCLC showed a reduction in ‘BFDG
`uptake on PET scanning after week 3. S6K1 activity in PBMCs was
`inhibited for 3-5 days at 5 and 10 mg dose levels. At doses 220mg 7/8
`patients exhibited inhibition for at
`least 7 days. Conclusions: Weekly
`administration of 20mg RAD001 in patients, gives plasma concentrations
`and sustained S6Kl inhibition equivalent to the PK levels and PD changes
`that correlate with anti-tumour effects in rodents treated with this sched-
`ule. Doses above 20mg result
`in only marginally increased inhibition.
`Combination studies have been initiated and we continue to explore the PD
`impact of mTOR inhibition in human tumours.
`
`ever,our data suggest that cdk activity can be inhibited in tumor cells, resulting
`in a post-treatment modulation of Rb phosphorylatlon.
`In the absence of
`cytotoxic activity, more frequent administration of E7070 may be required to
`sustain Rb hypophosphorylation and cytostatlc growth arrest.

`A phase I trial of an oral histone tleacetylase inhibitor, MS-275, in advanced
`solid tumor and lymphoma patients. 0. C. Ryan, D. Headiee, A. Sparreboom,
`W. Figg, S. Zhai, J. Trepel, A. Murgo, Y. Elsayed, J. Karp, E. Sausville;

`Baltimore, MD
`We are conducting a Phase l trial using MS-275, an orally administered,
`synthetic histone dcacetylase inhibitor,
`in advanced solid tumor and
`lymphoma patients. The trial initially used a daily x 28, repeated every six
`weeks, dosing schedule with an accelerated titration design, beginning at 2
`mg/m2 (i.e., 1/10 of rat maximal
`tolerated dose (MTD}). However,
`in
`humans the MTD was exceeded at the 1st dose level, with grade 3 AST,
`hyposphosphatemia, hypoalbuminemia, pleural effusion and epigastric
`pain, Preliminary evidence of a substantially longer half-life of MS—275 in
`humans as compared to preclinical species likely accounts for this finding.
`A once q14 day schedule was then implemented, also starting at 2 mg/m2
`but escalating with 2 mg/m2 increments. To date, 20 patients have been
`treated on this schedule. Although escalated to level 5 (10 mg/m2 q 2 wk),
`the MTD has not yet been reached. Frequent grade 1-2 toxicities include
`fatigue (50%); nausea (50%); hypoalbuminemia (35%), headache (35%),
`anxiety (30 %), dyspepsia (30%), vomiting (30%); dysgeusia (20%),
`anemia (20%), fever (20%), and hyponatremia (20%). Besides the first
`course toxicities, hypoalbuminemia and progressive fatigue as a continuing
`effect of MS-275 occurred, especially at higher dose levels, and are of
`concern for long term dosing. Peak plasma concentrations were observed at
`6 - 24 h after dosing, suggesting slow absorption, and in the range of 10 -
`50 nglml. This concentration is within the range that might affect
`proliferation of certain cell
`types preclinically. Dose dependence of
`exposure to MS-275 occurred, but no further increase in area under the
`curve at doses above 6 mg/m2 was evident. This phenomenon likely
`involves nonlinear, apparent saturable absorption processess.
`increased
`histone H3 acetylation in peripheral blood mononuclear cells was apparent
`at all dose levels, by immunofluorescent analysis. Based on these data, a
`new oral schedule, weekly x4, repeated every six weeks, as well as an
`intravenous formulation are being developed.
