Target Recruitment
89
Inclusion Criteria
  • Confirmed diagnosis of malignant pleural mesothelioma (MPM) with the following characteristics: unresectable disease (or otherwise not a candidate for curative surgery); epithelial type or biphasic (mixed) type with low sarcomatous content.
  • Measurable disease at Screening by computed tomography (CT)(or magnetic resonance imaging [MRI]).
  • KPS of greater than or equal to 70% at Screening.
  • Life expectancy of at least 3 months

Primary

Exclusion Criteria
  • Sarcomatous type of mesothelioma
  • Prior systemic therapy or radiotherapy for MPM; local radiotherapy for symptom control (ie, non-curative intent) is permitted.
  • Confirmed presence of CNS tumor involvement.
  • Evidence of other active malignancy requiring treatment.

Primary Outcome Measures
NameTimeMethod
Number of Participants With Progression Free Survival (PFS) Responders and Non-responders at Month 6Month 6

Number of participants with PFS responders and non-responders at Month 6 was reported. PFS was defined as the time from the date of the first dose of amatuximab to the date of disease progression or death due to any cause, as determined by independent radiologist based on the modified Response Evaluation Criteria in Solid Tumors (RECIST) utilizing the total tumor measurement (performed by computerized tomography (CT)/magnetic resonance imaging (MRI)) which includes the pleural unidimensional measure plus the total of the target lesion(s) measurement. A "response", in terms of PFS, was defined to be at least a 6-month stabilization of disease. Progressive disease (PD) as measured by Modified RECIST was defined as an increase of at least 20 percent (%) in the total tumor measurement over the nadir measurement, or the appearance of one or more new lesions.

Secondary Outcome Measures
NameTimeMethod
Time to Tumor Response (TTR)From the date of the first dose to first documentation of objective response, up to approximately 5 years

TTR was derived for those participants with objective evidence of CR or PR. TTR was defined as the time from the date of the first dose of amatuximab to first documentation of objective tumor response. CR was defined as the disappearance of all target lesions with no evidence of tumor elsewhere, and PR was defined as at least a 30% reduction in the total tumor measurement.

Overall Survival (OS)From the date of first dose to the date of death, up to approximately 5 years

OS was defined as the time from the date of the first dose of amatuximab to the date of death.

Overall Response Rate (ORR)From the date of first dose until evidence of CR or PR, up to approximately 5 years

ORR, defined as the percentage of participants with objective evidence of complete response (CR) or partial response (PR) as determined by independent radiologist based on the modified RECIST utilizing the total tumor measurement (performed by CT/ MRI) which includes the pleural unidimensional measure plus the total of the target lesion(s) measurement. Tumor assessments performed up to the initiation of further anticancer therapy were considered. CR was defined as the disappearance of all target lesions with no evidence of tumor elsewhere, and PR was defined as at least a 30% reduction in the total tumor measurement. A confirmed response required a repeat observation on two occasions 4 weeks apart. ORR = CR + PR.

Duration of Response (DR)From the first documentation of objective response (CR or PR) to the first documentation of disease progression, up to approximately 5 years

DR was derived for those participants who achieved a PFS Response and had an objective evidence of CR or PR. DR was defined as the time (in months) from first documentation of objective response (CR or PR) to the first documentation of disease progression or death \[as determined by independent radiologist based on the modified RECIST utilizing the total tumor measurement (performed by CT/ MRI) which includes the pleural unidimensional measure plus the total of the target lesion(s) measurement\]. Tumor assessments performed up to the initiation of further anticancer therapy were considered. CR was defined as the disappearance of all target lesions with no evidence of tumor elsewhere, and PR was defined as at least a 30% reduction in the total tumor measurement. PD as measured by Modified RECIST was defined as an increase of at least 20% in the total tumor measurement over the nadir measurement, or the appearance of one or more new lesions.

Overall Progression Free SurvivalFrom the date of first dose of amatuximab to the date of disease progression, up to approximately 5 years

Overall PFS was defined as the time from the date of first dose of amatuximab to the date of disease progression or death due to any cause. In the absence of confirmation of death, the survival time was censored at the date of the last follow-up contact. Tumor assessments performed up to the initiation of further anticancer therapy were considered. PD as measured by Modified RECIST was defined as an increase of at least 20% in the total tumor measurement over the nadir measurement, or the appearance of one or more new lesions.
