Ovarian Cancer Clinical Trial

Study of Carfilzomib With Irinotecan in Irinotecan-Sensitive Malignancies and Small Cell Lung Cancer Patients

Summary

The purpose of this study is to determine a well-tolerated dose of Carfilzomib in combination with Irinotecan (Phase 1b portion of the study) in subjects with relapsed small and non-small cell lung cancer or other irinotecan-sensitive cancers and to assess the 6 month survival of relapsed small cell lung cancer patients treated with this combination therapy. **The Phase 1b portion of the study is now complete**.

Phase 2 portion of the study. The safest, maximally tolerated dose established as established in Phase 1 for Phase 2 is as follows -- Carfilzomib will be provided at 20/36 mg/m2 with Irinotecan dosed at 125 mg/m2. The purpose of the Phase 2 portion of the study is to assess 6 month survival of relapsed small cell lung cancer ins subjects treated with this combination therapy.

Full Description

Small cell lung cancer accounts for approximately 15% of all lung cancer diagnoses in the United States (US), with 60-80% response rates to platinum-based chemotherapy in extensive disease. Despite its sensitivity to chemotherapy, small cell lung cancer is characterized by its tendency to spread to other locations in the body such as the bloodstream and other organs such as the liver. Currently, the only FDA-approved second-line therapies are oral and parenteral topotecan, although irinotecan is also commonly used in primary and relapsed disease. Novel combination therapies are desperately needed in this disease. in order to improve survival.

Carfilzomib (also known as Kyprolis) is an anti-cancer drug classified as a selective proteasome inhibitor. Proteasome inhibition affects the levels of numerous cell cycle control proteins, apoptosis (i.e., cell death), cell adhesion, angiogenesis, and chemoresistance proteins. Chemically, it is similar to epoxomicin.

Carfilzomib and other proteasome inhibitors interrupt cellular pathways integral to the survival of small cell lung cancer, namely the apoptotic pathway involving activated Nuclear Factor-kB (referenced as NF-kB). NF-kB activates the transcription of anti-apoptotic and proliferation genes, mediating tumor cell survival in response to cytotoxic stress thus resulting in chemoresistance, a common problem in small cell lung cancer. Carfilzomib prevents the breakdown of IkappaB (referenced as IkB), a protein which inhibits NF-kB, controls levels of the anti-apoptotic gene Bcl-2 and the tumor suppressor p53. Overexpression of Bcl-2, a key mediator of resistance to apoptosis following chemotherapy, which is an important problem in small cell lung cancer.

In this trial, Carfilzomib is combined with Irinotecan. Irinotecan, a camptothecins, inhibits topoisomerase I, thought to be important in the growth and spread of cancer. As a class, camptothecins have shown efficacy in small cell lung cancer in a variety of settings.

Topoisomerase-1 is thought to cause apoptosis via mechanisms other than NF-kB, adding to the potential synergy of these compounds. In addition, topoisomerase-1 is overexpressed in the majority of subjects with small cell lung cancer and decreased degradation of this enzyme is expected to lead to further enhancement of this mechanism of apoptosis

The pivotal phase III study which led to FDA approval of topotecan in relapsed small cell lung cancer was by Von Pawel et al, and included 211 subjects with sensitive (> 60 days since prior therapy) relapse and randomized them to either topotecan (107 subjects) daily for 5 days or to cyclophosphamide, doxorubicin, and vincristine (CAV), each given every 21 days. Topotecan showed no significant improvement in the median time to progression (13.3 weeks vs.12.3 weeks, p=0.552) or median survival (25 weeks vs. 24.7 weeks, p=0.795), however, subjects treated with topotecan had improvement in cancer-related symptoms (dyspnea, hoarseness, anorexia, and fatigue) as well as hematologic toxicity. Irinotecan, has established activity in small cell lung cancer, as well as non-small cell lung cancer, colorectal cancer and ovarian cancer.

In this Phase 2 study patients will be treated with the Maximum Tolerated Dose (MTD) of Carfilzomib 20/36 mg/m^2 as stepped up dosing determined in Phase 1b and 125mg/m^2 of Irinotecan.

Eligibility Criteria

Inclusion Criteria:

Patients must have histologically or cytologically-confirmed diagnosis of progressive or recurrent malignancy as follows:
Phase II: extensive stage small cell lung cancer with progression or recurrence after exactly one platinum-containing regimen. Patients who progressed during or within one month of completing platinum-based chemotherapy will be excluded. Patients who received primary curative chemoradiation therapy for limited disease, but who recur within the primary tumor site, previously radiated field or with distant metastases are also allowed to participate. Patients who have clinical evidence of recurrent small cell lung cancer do not require a confirmatory biopsy to be eligible for this trial. Prior irinotecan is not allowed.
Patients must have measurable disease per RECIST criteria 1.1 performed within 28 days prior to enrollment. All other required tests to assess non-measurable disease must be performed within 42 days prior to enrollment.
Patients with known brain metastases are eligible only if he/she has been treated for brain metastasis, are asymptomatic after treatment, have a stable CT or MRI of the brain within 28 days of enrollment and are not receiving corticosteroid therapy to control symptoms from brain metastasis. Only a non-enzyme inducing anticonvulsant (e.g., Keppra) will be permitted for those patients requiring anticonvulsants. (Topical and/or inhaled steroids are allowed.)
Patients may have received previous radiation therapy, but it must have been completed at least 21 days prior to enrollment and the patient should have recovered from all associated toxicities. Measurable or non-measurable disease must be present outside the previous radiation field or a new lesion inside the radiation port must be present.
Patients may have received prior surgery provided that at least 28 days have elapsed since major surgery (thoracic or other major surgeries) and the patient has recovered from all associated toxicities. Patients must have disease outside of the previous surgical resection area or a new lesion must be present.
