Study of Dalantercept and Axitinib in Patients With Advanced Renal Cell Carcinoma
- Conditions
- Advanced Renal Cell Carcinoma
- Interventions
- Registration Number
- NCT01727336
- Lead Sponsor
- Acceleron Pharma, Inc., a wholly-owned subsidiary of Merck & Co., Inc., Rahway, NJ USA
- Brief Summary
The purpose of Part 1 of this study is to evaluate the safety and tolerability of dalantercept in combination with axitinib in patients with advanced renal cell carcinoma (RCC) to determine the recommended dose level of dalantercept in combination with axitinib for Part 2.
The purpose of Part 2 of this study is to determine whether treatment with dalantercept in combination with axitinib prolongs progression free survival (PFS) compared to axitinib alone in patients with advanced renal cell carcinoma (RCC).
- Detailed Description
In Part 1 of the study, groups of subjects received escalating doses of dalantercept; 0.6, 0.9 and 1.2 mg/kg in sequential groups. All subjects received concurrent axitinib 5 mg PO BID. A total of 29 subjects were enrolled i Part 1 of the study.
In Part 2, dalantercept at 0.9 mg/kg once every 3 weeks plus axitinib 5 mg PO BID was compared to placebo plus axitinib 5 mg PO BID. A total of 131 subjects were enrolled in Part 2 for a total of 160 in the study

For clinically significant epistaxis within 4 weeks prior to study day 1, no risk of further bleeding must be clearly documented.
- Known history of hereditary hemorrhagic telangiectasia (HHT).

- History of severe (defined as ≥ grade 3, using the National Cancer Institute Common Toxicity Criteria for Adverse Events, version 4.0 [NCI-CTCAE] v4 current active minor version) allergic or anaphylactic reaction or hypersensitivity to recombinant proteins or excipients (10 mM Tris buffered saline) in the investigational agent.
- Any prior treatment with dalantercept or any other agent targeting ALK1 pathway.
- Any prior treatment with axitinib.
- A morbidity (per the prescribing information) that would require starting a patient at a reduced dose of axitinib.
- Treatment with another investigational drug (with the exception of anticancer immune therapy) or device, or approved therapy for investigational use, within 5 times the half-life of the drug or within 3 weeks prior to study day 1 if the half life is not known.

- Primary Outcome Measures
Name Time Method Part 1: Number of Participants With Adverse Events as a Measure of Safety and Tolerability. Assessed from time of first dose to approximately 30 days after last dose. Participants were allowed to remain on treatment until documented disease progression. The time frame for Part 1 of the study was up to 21.6 months Outcome measure is intended for Part 1 of the study in order to determine recommended dose level for Part 2.
Part 2: Progression Free Survival (PFS). Progression free survival is defined as the time from the date of the randomization to the first documented disease progression (according to RECIST v1.1) or death due to any cause. The Time frame for Part 2 was up to 29.0 months PFS was defined as the time from randomization to the date of first documentation of disease progression based on RECIST (version 1.1) or to death due to any cause, whichever occurred first. Disease progression is defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study.
RECIST 1.1 defines disease progression as an increase of at least a 20% in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered progression)
- Secondary Outcome Measures
Name Time Method Part 1: Objective Response Rate (ORR) Up to 21.6 months from randomization in Part 1 of the study Objective response rate (ORR) is defined as the number and percentage of patients who have a partial response (PR) or complete response (CR) to therapy. A CR is defined as the disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. A PR is defined as a decrease of at least a 30% in the sum of diameters of target lesions, taking as reference the baseline sum diameters. As no subjects in Part 1 experienced a CR, the ORR in Part 1 is defined by the PR
Part 1: Progression Free Survival (PFS). The time frame for Part 1 of the study was up to 21.6 months PFS was defined as the time from randomization to the date of first documentation of disease progression based on RECIST (version 1.1) or to death due to any cause, whichever occurred first. Disease progression is defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study.
Part 2: Overall Survival. Patients to be contacted every 3 months for up to 12 months (anticipated) for survival follow-up, as well as tumor assessment scans if progression of disease has not previously been documented. The time frame for Part 2 was up to 29.0 months The number of months from the date of randomization to the date of death.
Part 1: Overall Survival (OS). [The Time Frame for Part 1 of the Study Was up to 21.6 Months] Up to 21.6 months Percentage of Part 1 subjects alive at the end of Part 1 of the study. \[The time frame for Part 1 of the study was up to 21.6 months\]
Part 2: Progression Free Survival (PFS) for the Subset of Participants With 2 or More Lines of Prior Systemic Chemotherapy Progression free survival is defined as the time from the date of the randomization to the first documented disease progression (according to RECIST v1.1) or death due to any cause. The Time frame for Part 2 was up to 29.0 months Progression Free Survival (PFS) for the subset of participants with 2 or more lines of prior systemic chemotherapy. PFS was based upon RECIST 1.1 assessment, as described in outcome measure 2.
Part 1: Disease Control Rate (DCR) From randomization up to 21.6 months in Part 1 of the study The number and percentage of patients whose disease shrinks or remains stable. DCR is the sum of the complete, partial and stable disease rates.
Part 1: Duration of Response (DoR) From randomization up to 21.6 months in Part 1 of the study. Response duration is measured from the time measurement criteria are first met for objective response until the first date that recurrent or progressive disease is objectively documented (taking as reference for progressive disease the smallest measurements recorded on study.
Part 2: Duration of Response Assessed at 30 days after the last dose of study drug; up to 29.0 months for Part 2 of the study. Response duration is measured from the time measurement criteria are first met for objective response until the first date that recurrent or progressive disease is objectively documented (taking as reference for progressive disease the smallest measurements recorded on study.
Part 2: Disease Control Rate. Assessed at 30 days after last dose of study drug. The time frame for Part 2 was up to 29.0 months The number and percentage of patients whose disease shrinks or remains stable. DCR is the sum of the complete, partial and stable disease rates.
Part 2: Objective Response Rate. Assessed at 30 days after last dose of study drug; up to 29.0 months for Part 2 of the study Objective response rate (ORR) is defined as the number and percentage of patients who have a partial response (PR) or complete response (CR) to therapy. A CR is defined as the disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. A PR is defined as a decrease of at least a 30% in the sum of diameters of target lesions, taking as reference the baseline sum diameters.
