Advanced Non-Small Cell Lung Cancer
Brief summary
The purpose of this study is to compare disease response of Albumin-bound paclitaxel (ABI-007) plus Carboplatin versus Taxol and Carboplatin as first-line therapy in patients with advanced non-small cell lung cancer (NSCLC).
Interventions
Administered by intravenous infusion.
Administered by intravenous infusion.
Administered by intravenous infusion. Dosing was based on the Calvert formula: carboplatin dose (mg) = (Target AUC) x (glomerular filtration rate \[GFR\] + 25). For the purposes of this protocol, the GFR is considered to be equivalent to creatinine clearance (calculated by the method of Cockcroft and Gault, 1976).

Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of Participants Who Achieved an Objective Confirmed Complete Response or Partial Response by Blinded Radiology Assessment | Objective response was evaluated every 6 weeks until progression or new anti-cancer therapy initiation, up to 22 months. | Antitumor response was defined as the percentage of participants who achieved an objective response (Confirmed Response \[CR\] or Partial Response \[PR\]), confirmed by repeat assessments performed no less than 4 weeks after the criteria for response were first met. Response was based on the blinded radiological review using Response Evaluation Criteria in Solid Tumors (RECIST) response guidelines, Version 1.0. A complete response was defined as a disappearance of all target and non-target lesions and no new lesions. Partial response was defined as ≥ 30% decrease in the sum of the longest diameters (SLD) of target lesions, taking as reference the baseline SLD, and the persistence of one or more non-target lesions not qualifying for CR or Progressive Disease (the unequivocal progression of existing non-target lesion(s) or appearance of one or more new lesions). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Overall Participant Survival | Up to 38 months | Overall survival was defined as the time from the day of randomization to participant death (due to any cause), as assessed by post study follow-up performed monthly for 6 months and every 3 months thereafter for 12 months. All participants who were lost to the follow-up prior to the end of the trial or who completed the 18 month follow up phase were censored at last known time the participant was alive. |
| Percentage of Participants With Controlled Disease | Assessed every 6 weeks, up to 22 months | Controlled disease was defined as the percentage of participants with stable disease for ≥ 16 weeks or confirmed complete or partial overall response, based on blinded radiological assessment. Stable disease was defined as neither sufficient shrinkage of target lesions to qualify for Partial Response, nor sufficient increase to qualify for Progressive Disease, or the persistence of one or more non-target lesions not qualifying for Complete Response or Progressive Disease. |
| Duration of Response in Responding Patients | Assessed every 6 weeks, up to 38 months | Duration of response was assessed by progression free survival for participants who achieved a confirmed complete response or partial response based on blinded radiological assessment. |
| Number of Participants With Adverse Events (AEs) | Up to 38 months | A Treatment-emergent AE was any AE that began or worsened in grade after the start of study drug through 30 days after the last dose of study drug or end of study whichever is later. Treatment related toxicity was one considered by the investigator to be possibly, probably or definitely related to study drug. AEs were graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) v3.0 on the following scale: Grade 1 = mild, Grade 2 = moderate, Grade 3 = severe, Grade 4 = life-threatening, Grade 5 = death. A serious adverse event (SAE) is any untoward medical occurrence at any dose that: is fatal or life-threatening; results in persistent or significant disability or incapacity; requires or prolongs in-patient hospitalization; is a congenital anomaly/birth defect in the offspring of a patient; and conditions not included in the above that may jeopardize the patient or may require intervention to prevent one of the outcomes listed above. |
| Pharmacokinetic (PK) Parameters | Blood samples for PK analyses were taken during Cycle 1 at 0.25, 3.5 and 24 hours post-infusion. | — |
| SPARC Status and Correlation With Overall Survival | Archival tissue samples were used for SPARC analysis. Survival was assessed for up to 38 months. | The expression and cellular distribution of Secreted Protein Acidic and Rich in cysteine (SPARC) in biopsies of lung tumor was examined by immunohistochemistry using a 2 antibody system by an approved central laboratory and analyzed by 2 pathologists. The following tissue components were scored: tumor cells, fibroblasts, inflammatory cells, acellular stroma/matrix, and blood vessels. To classify participants into high-SPARC and low-SPARC groups, an average z-score was calculated across variables and classified high-SPARC (average z-scores ≥0) and low-SPARC (average z-scores \<0) groups. SPARC status was then correlated with overall survival (the time from the day of randomization to participant death due to any cause). |
| Progression-free Survival by Blinded Radiology Assessment | Assessed every 6 weeks until progression or death, up to 38 months | Progression free survival time was defined as the time from the day of randomization to the start of disease progression or death (any cause), whichever occurred first, based on the blinded radiological review response assessment. Progressive disease was defined as a ≥ 20% increase in the SLD of target lesions, taking as reference the nadir SLD recorded since the treatment started, or the presence of one or more new lesions, or the unequivocal progression of existing non-target lesion(s) or appearance of one or more new lesion(s). Participants who did not have disease progression or had not died were censored at the last visit they were documented as progression free. If palliative radiotherapy or surgery at lesion sites occurred, the participant was censored at the last date without documented progression prior to radiotherapy or surgery. In follow-up, participants who began new therapy prior to progression were censored at the last documented date as progression-free. |

Progression free survival time was defined as the time from the day of randomization to the start of disease progression or death (any cause), whichever occurred first, based on the blinded radiological review response assessment. Progressive disease was defined as a ≥ 20% increase in the SLD of target lesions, taking as reference the nadir SLD recorded since the treatment started, or the presence of one or more new lesions, or the unequivocal progression of existing non-target lesion(s) or appearance of one or more new lesion(s). Participants who did not have disease progression or had not died were censored at the last visit they were documented as progression free. If palliative radiotherapy or surgery at lesion sites occurred, the participant was censored at the last date without documented progression prior to radiotherapy or surgery. In follow-up, participants who began new therapy prior to progression were censored at the last documented date as progression-free.
Time frame: Assessed every 6 weeks until progression or death, up to 38 months

The expression and cellular distribution of Secreted Protein Acidic and Rich in cysteine (SPARC) in biopsies of lung tumor was examined by immunohistochemistry using a 2 antibody system by an approved central laboratory and analyzed by 2 pathologists. The following tissue components were scored: tumor cells, fibroblasts, inflammatory cells, acellular stroma/matrix, and blood vessels. To classify participants into high-SPARC and low-SPARC groups, an average z-score was calculated across variables and classified high-SPARC (average z-scores ≥0) and low-SPARC (average z-scores \<0) groups. SPARC status was then correlated with overall survival (the time from the day of randomization to participant death due to any cause).
Time frame: Archival tissue samples were used for SPARC analysis. Survival was assessed for up to 38 months.

Percentage of Participants Who Achieved an Objective Confirmed Complete Response or Partial Response by Blinded Radiology Assessment, by Histology
Antitumor response was defined as the percentage of participants who achieved an objective response (Confirmed Response \[CR\] or Partial Response \[PR\]), confirmed by repeat assessments performed no less than 4 weeks after the criteria for response were first met. Response was based on the blinded radiological review using Response Evaluation Criteria in Solid Tumors (RECIST) response guidelines, Version 1.0. A complete response was defined as a disappearance of all target and non-target lesions and no new lesions. Partial response was defined as ≥ 30% decrease in the sum of the longest diameters (SLD) of target lesions, taking as reference the baseline SLD, and the persistence of one or more non-target lesions not qualifying for CR or Progressive Disease (the unequivocal progression of existing non-target lesion(s) or appearance of one or more new lesions). Histology was determined at the time of primary diagnosis.
Time frame: Objective response was evaluated every 6 weeks until progression or new anti-cancer therapy initiation, up to 22 months.
Population: The intent-to-treat population. N indicates the number of participants in each histology category for each treatment arm respectively.
| Arm | Measure | Group | Value (NUMBER) |
|---|---|---|---|
| Albumin-bound Paclitaxel + Carboplatin | Percentage of Participants Who Achieved an Objective Confirmed Complete Response or Partial Response by Blinded Radiology Assessment, by Histology | Carcinoma/Adenocarcinoma [254, 264] | 26 percentage of participants |
| Albumin-bound Paclitaxel + Carboplatin | Percentage of Participants Who Achieved an Objective Confirmed Complete Response or Partial Response by Blinded Radiology Assessment, by Histology | Squamous Cell Carcinoma [229, 221] | 41 percentage of participants |
| Albumin-bound Paclitaxel + Carboplatin | Percentage of Participants Who Achieved an Objective Confirmed Complete Response or Partial Response by Blinded Radiology Assessment, by Histology | Large Cell Carcinoma [N=9, 13] | 33 percentage of participants |
| Albumin-bound Paclitaxel + Carboplatin | Percentage of Participants Who Achieved an Objective Confirmed Complete Response or Partial Response by Blinded Radiology Assessment, by Histology | Other [N=29, 33] | 24 percentage of participants |
| Paclitaxel + Carboplatin | Percentage of Participants Who Achieved an Objective Confirmed Complete Response or Partial Response by Blinded Radiology Assessment, by Histology | Other [N=29, 33] | 15 percentage of participants |

| Paclitaxel + Carboplatin | Percentage of Participants Who Achieved an Objective Confirmed Complete Response or Partial Response by Blinded Radiology Assessment, by Histology | Large Cell Carcinoma [N=9, 13] | 15 percentage of participants |
| Paclitaxel + Carboplatin | Percentage of Participants Who Achieved an Objective Confirmed Complete Response or Partial Response by Blinded Radiology Assessment, by Histology | Squamous Cell Carcinoma [229, 221] | 24 percentage of participants |
Time to Improvement of ≥ Grade 3 Treatment Related Peripheral Neuropathy
Peripheral neuropathy was graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 3.0 on the following scale: Grade 1 = mild, Grade 2 = moderate, Grade 3 = severe, Grade 4 = life-threatening, Grade 5 = death. Improvement in peripheral neuropathy was evaluated as: * Time to improvement of grade 3 or higher peripheral neuropathy by at least one grade; * Time to improvement of grade 3 or higher peripheral neuropathy to grade 1. Time to improvement was defined as the time from the first occurrence of grade 3 or higher treatment related neuropathy to improvement, as defined. Participants not experiencing improvement were censored at the last time the participant was evaluated for adverse events.
Time frame: 38 months
Population: Treated population with ≥ grade 3 treatment-related peripheral neuropathy.
| Arm | Measure | Group | Value (MEDIAN) |
|---|---|---|---|
| Albumin-bound Paclitaxel + Carboplatin | Time to Improvement of ≥ Grade 3 Treatment Related Peripheral Neuropathy | Improvement by ≥1 grade | 24.0 days |
| Albumin-bound Paclitaxel + Carboplatin | Time to Improvement of ≥ Grade 3 Treatment Related Peripheral Neuropathy | Improvement to grade 1 | 38.0 days |
| Paclitaxel + Carboplatin | Time to Improvement of ≥ Grade 3 Treatment Related Peripheral Neuropathy | Improvement by ≥1 grade | 26.0 days |
| Paclitaxel + Carboplatin | Time to Improvement of ≥ Grade 3 Treatment Related Peripheral Neuropathy | Improvement to grade 1 | 104.0 days |
