Trial Outcomes & Findings for MDX-010 Antibody, MDX-1379 Melanoma Vaccine, or MDX-010/MDX-1379 Combination Treatment for Patients With Unresectable or Metastatic Melanoma (NCT NCT00094653)

NCT ID: NCT00094653

Last Updated: 2011-07-11

Results Overview

OS was defined as the time from randomization until death from any cause. If a participant did not expire, the subject was censored at the time of last contact (last known alive date). 95% confidence intervals (CI) for median were computed using Brookmeyer and Crowley method.

Measure
Ipilimumab Plus gp100
Ipilimumab was administered at a dosage of 3 mg/kg as an intravenous (IV) infusion administered over 90 minutes every 3 weeks for a total of 4 doses, together with gp100. Gp100 consisted of 2 separate peptide components: Peptide A, a peptide with sequence YLEPGPVTV (gp100:280-288\[288V\]) and Peptide B, a peptide with the sequence IMDQVPFSV (gp100:209-217\[210M\]). Each peptide was prepared with Montanide ISA-51. One dose of gp100 consisted of the administration of Peptide A, at a dosage of 2 mL or 1 mg, and Peptide B, at a dosage of 2 mL or 1 mg. After Week 12, subjects who met re-induction criteria could receive further cycles of their randomized study therapy.
Ipilimumab Monotherapy
Ipilimumab was administered at a dosage of 3 mg/kg as an intravenous (IV) infusion administered over 90 minutes every 3 weeks for a total of 4 doses, together with matching vaccine placebo. The vaccine placebo consisted of sterile 0.9% sodium chloride. After Week 12, subjects who met re-induction criteria could receive further cycles of their randomized study therapy.

Population: Intent-to-treat population, as randomized. All subjects who were randomized to any treatment group in the study. Subjects who neither progressed nor died were censored at the date of the last tumor assessment.

PFS was defined as the number of days between the date of randomization and the date of the progression or the date of death. A subject who died without prior progression was considered to have progressed on the date of death. PFS was determined by investigator. 95% confidence intervals (CI) for median were computed using Brookmeyer and Crowley method.

Population: Intent-to-treat population, as randomized. All subjects who were randomized to any treatment group in the study.

TTP was defined as the number of days between the date of the randomization and date of PD or death due to PD. For subjects who had not progression and remained alive, TTP was censored on the date of last assessment; those who remained alive and had no recorded post-baseline assessment, TTP was censored on the date of randomization; those who remained alive and had randomized but were not treated, TTP was censored at the date of randomization; for those who died without reported disease progression, TTP was censored on the date of death.

Population: Intent-to-treat population, as randomized. All subjects who were randomized to any treatment group in the study.

Response was based on the investigators' assessment using modified WHO criteria. BORR is defined as the number of subjects whose BOR is complete or partial response (CR or PR) divided by the total number of subjects in the group. BORR was comprised of responder and non-responder. The definition of a responder in BORR was either confirmed CR or PR, and a non-responder was defined as stable disease (SD), progressed disease (PD), unconfirmed CR (uCR), unconfirmed PR (uPR), and not evaluated.

Interval 5.36 to
Upper limit of 95% CI was not reached because most subjects were censored and the upper bound was not estimable.

Interval 28.09 to
Median duration of response was not reached because of the number of ongoing responses (ie, since most subjects did not progress-die, the median was not reached).
NA months
Interval 2.0 to
The limited number of responses (2) in the gp100 monotherapy group prevented a median duration from being reached.

All scores were linearly transformed to a 0 to 100 scale. For global QOL and functional items, a higher score represents a better level of functioning (100=best/0=worst). For symptom items, a higher score represents a higher level of symptoms (0=no symptom at all/100=very much severe).

SECONDARY outcome

Timeframe: On-study adverse events include all AEs reported between the first dose and 70 days after the last dose of study therapy (end of the study was defined as the time at which 481 deaths were observed [264 weeks]).

Population: All subjects who received at least 1 dose or any partial dose of study medication.

An AE was defined as any undesirable sign, symptom, clinically significant laboratory abnormality, or medical condition occurring after starting study treatment, even if the event was not considered to be treatment-related. Adverse events are graded using the Cancer Therapy Evaluation Program (CTEP) Common Terminology Criteria for Adverse Events (CTCAE), Version 3.0. If CTCAE grading does not exist for an adverse event, the intensity of mild (1), moderate (2), severe (3), and life-threatening (4) were used.

An immune related adverse event (irAE) was defined as an adverse event of unknown etiology, associated with study drug exposure and consistent with an immune phenomenon. The irAEs were programmatically determined from a predefined list of MedDRA version 12.0 high-level group terms, high-level terms and preferred terms of all ipilimumab related adverse event. The category of "Other irAEs" includes blood, eye, immune, infections, renal, and respiratory systems.

SECONDARY outcome

Timeframe: On-study adverse events include all AEs reported between the first dose and 70 days after the last dose of study therapy (end of the study was defined as the time at which 481 deaths were observed [264 weeks]).

Population: All subjects who received at least 1 dose or any partial dose of study medication. N=Number of participants analyzed; n=number of participants with given laboratory evaluation.

CTCAE v3.0 Grades 0 through 4 of severity for each AE based on this general guideline: Grade 0=Normal, Grade 1=Mild AE, Grade 2=Moderate AE, Grade 3=Severe AE, Grade 4=Life-threatening or disabling AE.

Ipilimumab Plus gp100
n=380 Participants
Ipilimumab was administered at a dosage of 3 mg/kg as an intravenous (IV) infusion administered over 90 minutes every 3 weeks for a total of 4 doses, together with gp100. Gp100 consisted of 2 separate peptide components: Peptide A, a peptide with sequence YLEPGPVTV (gp100:280-288\[288V\]) and Peptide B, a peptide with the sequence IMDQVPFSV (gp100:209-217\[210M\]). Each peptide was prepared with Montanide ISA-51. One dose of gp100 consisted of the administration of Peptide A, at a dosage of 2 mL or 1 mg, and Peptide B, at a dosage of 2 mL or 1 mg. After Week 12, subjects who met re-induction criteria could receive further cycles of their randomized study therapy.

Ipilimumab Monotherapy
n=131 participants at risk
Ipilimumab was administered at a dosage of 3 mg/kg as an intravenous (IV) infusion administered over 90 minutes every 3 weeks for a total of 4 doses, together with matching vaccine placebo. The vaccine placebo consisted of sterile 0.9% sodium chloride. After Week 12, subjects who met re-induction criteria could receive further cycles of their randomized study therapy.
Ipilimumab Plus gp100
n=380 participants at risk
Ipilimumab was administered at a dosage of 3 mg/kg as an intravenous (IV) infusion administered over 90 minutes every 3 weeks for a total of 4 doses, together with gp100. Gp100 consisted of 2 separate peptide components: Peptide A, a peptide with sequence YLEPGPVTV (gp100:280-288\[288V\]) and Peptide B, a peptide with the sequence IMDQVPFSV (gp100:209-217\[210M\]). Each peptide was prepared with Montanide ISA-51. One dose of gp100 consisted of the administration of Peptide A, at a dosage of 2 mL or 1 mg, and Peptide B, at a dosage of 2 mL or 1 mg. After Week 12, subjects who met re-induction criteria could receive further cycles of their randomized study therapy.
