Detailed Description
The role of the proteasome in carcinogenesis and cell survival has been well established, and its inhibition associated with an accumulation of pro-apoptotic proteins and cell death. Proteasome inhibitors, such has bortezomib, have been extensively studied and are widely used as effective therapy in the treatment for hematologic malignancies, such as multiple myeloma where circulating proteasome levels have been correlated with survival. Carfilzomib, a novel irreversible proteasome inhibitor which specifically targets the chymotryptic site of the proteasome has shown more potency than bortezomib and may be able to overcome bortezomib resistance. Response rates between 25-54% were seen in patients with previously treated myeloma in the phase 2 setting.
Given the effectiveness of proteasome inhibition in multiple myeloma, the role of proteasome in solid tumors is under active investigation. Previous trials of bortezomib in breast, prostate, lung, and pancreatic cancer have shown little activity of this agent in these diseases. Whether the lack of activity may be mechanistically related (bortezomib inhibits chymotrypsin-like and peptidyl-glutamyl peptide-hydrolyzing (PGPH)-like activities of the proteasome), or a lack of potency in target inhibition, is unknown.
In a phase Ib/II study of 14 patients (phase I) and 51 patients (phase II) with advanced solid tumors, Rosen and colleagues noted single-agent activity with carfilzomib. Carfilzomib was dosed on days 1, 2, 8, 9, 15, and 16 of a 28 day cycle to a maximum of 12 cycles, with 20-36 mg/m² noted as the recommended phase 2 dose based on DLT data. A PR in both renal and small cell lung cancer, and stable disease > 16 weeks in mesothelioma, ovarian, renal, and non-small cell lung cancer was observed. The treatment was tolerable with the most common adverse events (AEs) including fatigue, headache, diarrhea, nausea and constipation.
Given the activity of carfilzomib seen in selected solid tumors, and unpublished data to suggest weekly dosing may result in a similar pharmacokinetic profile including AUC, the investigators propose to study the safety, tolerability, pharmacokinetics, and anti-tumor activity of carfilzomib monotherapy given on a weekly dosing schedule. Weekly dosing has the advantage of patient convenience, and if acceptable toxicity and pharmacokinetics, it allows for easier integration of this schedule into subsequent combination therapy clinical trials.

Experimental: Carfilzomib
Patients will receive single agent carfilzomib on a weekly dosing schedule (days 1, 8, 15) in a 21 day cycle.
The initial dose will be 20 mg/m² for cycle 1, day 1.
Dose escalation will proceed in a standard 3+3 fashion with the requirement that dose escalation to the next level can only proceed if 0 of 3 or ≤ 1 of 6 patients experience a dose limiting toxicity (DLT).
Dexamethasone 8 mg PO/IV will be administered prior to all carfilzomib doses.
|
Carfilzomib will be given as an IV infusion over 4 hours.
Subjects will remain at the clinic under observation for at least 1 hour following each dose of carfilzomib in Cycle 1 and following the dose on Cycle 2 Day 1.
During these observation times, post dose IV hydration may be given at physician's discretion.
Other Names:
Dexamethasone 8 mg PO/IV will be administered prior to all carfilzomib doses.
