Study of Romiplostim for Chemotherapy-induced Thrombocytopenia in Adult Subjects With Non-small Cell Lung Cancer (NSCLC), Ovarian Cancer, or Breast Cancer

PROCLAIM: A Phase 3 Randomized Placebo-controlled Double-blind Study of Romiplostim for the Treatment of Chemotherapy-induced Thrombocytopenia in Patients Receiving Chemotherapy for Treatment of Non-small Cell Lung Cancer (NSCLC), Ovarian Cancer, or Breast Cancer

To evaluate the efficacy of romiplostim for the treatment of CIT in patients receiving chemotherapy for the treatment of NSCLC, ovarian cancer, or breast cancer measured by the ability to administer on-time, full-dose chemotherapy

Study Overview

• Status: Recruiting
• Conditions: Chemotherapy-induced Thrombocytopenia
• Intervention / Treatment: Drug: Placebo; Drug: Romiplostim

Detailed Description

This is a phase 3, randomized, placebo-controlled, multicenter, international study for the treatment of CIT in adult subjects receiving chemotherapy for the treatment of NSCLC, ovarian cancer, or breast cancer. Subjects must have a platelet count ≤ 85 x 10^9/L on day 1 of the study. The study will consist of a screening period of up to 4 weeks, a treatment period long enough to allow for assessment of 3 planned cycles of chemotherapy, a follow-up visit, and long-term follow-up (LTFU). Given that subjects are required to have 3 remaining planned cycles of chemotherapy, the chemotherapy cycles may be 3 or 4 weeks in duration, and the investigational product dose adjustment guidelines allow for up to 12 weeks of dosing before a subject is declared a non-responder, the majority of study subjects will receive investigational product for a range of 10-24 weeks.

• Subjects must have at least 3 remaining planned cycles of chemotherapy at study enrollment.
• Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2.

Exclusion Criteria:

• Acute lymphoblastic leukemia.
• Acute myeloid leukemia.
• Any myeloid malignancy.
• Myelodysplastic syndrome. Baseline bone marrow biopsy is not required to rule out MDS. However, if a bone marrow biopsy and cytogenetics were performed as part of diagnostic or staging work-up, these results will be collected to confirm.
• Myeloproliferative disease.
• Multiple myeloma.
• Within 4 months prior to enrollment, any history of active congestive heart failure (New York Heart Association [NYHA] Class III to IV), symptomatic ischemia, uncontrolled arrhythmias, clinically significant electrocardiogram (ECG) abnormalities, screening ECG with corrected QT (QTc) interval of greater than 470 msec, pericardial disease, or myocardial infarction.
• Major surgery less than or equal to 28 days or minor surgery less than or equal to 3 days prior to enrollment.
• New or uncontrolled venous thromboembolism or thrombotic events within 3 months prior to screening. To be eligible, subjects must have received at least 14 days of anticoagulation for a new thrombotic event and considered to be stable and suitable for continued therapeutic anticoagulation during trial participation.
• History of arterial thrombotic events (eg, myocardial ischemia, transient ischemic attack, or stroke) within 6 months prior to screening.
• Evidence of active infection within 2 weeks prior to the first dose of study treatment.
• Known human immunodeficiency virus infection with any detectable viral load at screening. Subjects without a documented diagnosis in their medical history will require a local laboratory assessment at screening. If local laboratory results are not available use central laboratory results.
• Known active of chronic hepatitis C or hepatitis B infection. Subjects without a documented diagnosis in their medical history will require a local laboratory assessment at screening. If local laboratory results are not available use central laboratory results. Hepatitis B and C infection is based on the following results:
• Positive for hepatitis B surface antigen (HBsAg) (indicative of chronic hepatitis B or recent acute hepatitis B).
• Negative HBsAg and positive for hepatitis B core antibody: hepatitis B virus DNA by polymerase chain reaction (PCR) is necessary. Detectable hepatitis B virus DNA suggests occult hepatitis B.
• Positive hepatitis C virus antibody: hepatitis C virus RNA by PCR is necessary. Detectable hepatitis C virus RNA suggests chronic hepatitis C.
• In addition to the conditions listed in exclusion criteria 201 through 206, secondary malignancy within the past 5 years except:
• Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease.
• Adequately treated cervical carcinoma in situ without evidence of disease.
• Adequately treated breast ductal carcinoma in situ without evidence of disease.
• Prostatic intraepithelial neoplasia without evidence of prostate cancer.
• Adequately treated urothelial papillary noninvasive carcinoma or carcinoma in situ.
• Malignancy treated with curative intent and with no known active disease present for greater than or equal to 3 years before enrollment and felt to be at low risk for recurrence by the treating physician (excluding malignancies listed in exclusion criteria 201 - 206).
• Thrombocytopenia due to another etiology other than CIT (eg, chronic liver disease, prior history of immune thrombocytopenia purpura).
• Any combined modality regimen containing radiation therapy or surgery occurring concomitantly with neo-adjuvant chemotherapy or where radiation therapy is planned during the cycle preceding 3 planned on-study cycles of chemotherapy.

Prior/Concomitant Therapy:

- Previous use of romiplostim, pegylated recombinant human megakaryocyte growth and development factor, eltrombopag, recombinant human TPO, any other TPO receptor agonist, or any investigational platelet producing agent.

Prior/Concurrent Clinical Study Experience - Currently receiving (or plan to receive) treatment in another investigational device or drug study, or less than 28 days since ending treatment on another investigational device or drug study(ies). Other investigational procedures while participating in this study are excluded.

Diagnostic Assessments

• Anemia (hemoglobin < 80 g/L [8 g/dL]) on the day of initiation of investigational product as assessed by local labs. Use of red cell transfusions and erythropoietic stimulating agents is permitted throughout the study as per institutional guidelines.
• Neutropenia (absolute neutrophil count less than 1 x 10 9/L) on the day of initiation of investigational product as assessed by local labs. Use of granulocyte-colony stimulating factor is permitted throughout the study as per institutional guidelines.
• Abnormal renal function with creatinine clearance less than 30 mL/min using the Cockcroft-Gault estimated creatinine clearance as assessed by local laboratory. If local laboratory results are not available use central laboratory results.

during screening.

- Abnormal liver function (total bilirubin greater than 3X ULN; alanine aminotransferase [ALT] or aspartate aminotransferase [AST] greater than 3X ULN for subjects without liver metastases or greater than or equal to 5X ULN for subjects with liver metastases) as assessed by local laboratory during screening. If local laboratory results are not available use central laboratory results.

Other Exclusions
