Open-Label Study of single agent IMO-2055
Patients who have Metastatic or Locally Recurrent Clear Cell Renal Carcinoma (RCC)
This is a study of 2 dose levels (0.16 or 0.64 mg/kg) of IMO-2055 administered by weekly subcutaneous (SC) injections in two patient populations, treatment naïve or previously treated patients. Each dose group (treatment naive or previously treated) will be randomized to receive one of the 2 doses being studied.

Drug IMO-2055

immunostimulatory oligonucleotide

Previous treatment, 0.16mg/kg Active Comparator

Patients will have clear cell renal carcinoma with previous treatment. Patients will receive weekly SC injections of IMO-2055 at a dose of 0.16mg/kg

Previous treatment, 0.64mg/kg Active Comparator

Patients will have clear cell renal carcinoma with previous treatment. Patients will receive weekly SC injections of IMO-2055 at a dose of 0.64mg/kg

Treatment Naive, 0.16mg/kg Active Comparator

Patients will have clear cell renal carcinoma without previous treatment. Patients will receive weekly SC injections of IMO-2055 at a dose of 0.16mg/kg

Treatment Naive, 0.64mg/kg Active Comparator

Patients will have clear cell renal carcinoma without previous treatment. Patients will receive weekly SC injections of IMO-2055 at a dose of 0.64mg/kg

Best Response by RECIST v1.0

Best overall objective (i.e., radiological) response by RECIST v1.0 for target lesions: Complete Response (CR): Disappearance of all target lesions; Partial Response (PR): At least a 30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR in patients with clear cell metastatic or locally recurrent renal cell carcinoma treated with IMO-2055.

Number of Participants With Treatment-emergent Adverse Events (TEAEs) by National Cancer Institute (NCI) Grade/Severity

Number of patients with Treatment-emergent adverse events (TEAEs) by National Cancer Institute (NCI) grade/severity that began on or after the date of the first injection of study drug or worsened in severity or frequency after study drug was administered.

Overall Survival at 1 Year

Overall survival is defined as (date of death +1 - date of randomization). Patients without an event (death) during treatment or follow-up will have their date censored on the last visit the patient was known to be alive.

Previous Treatment, 0.16mg/kg

Previous Treatment, 0.64mg/kg

Time to Disease Progression.

Time between the date of randomization to the Study Day of documented disease progression (an increase in tumor burden of at least 20%, appearance of new lesions, or unequivocal progression of non-measurable disease) or death (whichever comes first) by RECIST v1.0. Patients who had not progressed at last disease assessment, but whose progression status was unknown at the date last known alive, date of death, or date of study exit (whichever comes first), had event time censored at the date of last assessment. Patients who did not die and did not progress during treatment or follow-up had their event time censored on the last contact date.
