Trial Of PF-00299804 In Patients With Advanced Refractory Lung Cancer

PFS6m was defined as percent chance of being event free (event defined as PD or death due to any cause, whichever occurred first) at 6 months. Progression was defined using RECIST, as at least 20% increase in the sum of longest dimensions (LD) of target lesions, taking as reference the smallest sum of LD recorded since the treatment started and/or unequivocal progression of existing non-target lesions and/or appearance of 1 or more new lesions.

OS6m was defined as percent chance of being alive at Month 6.

Percentage of participants with objective response based on assessment of confirmed complete response (CR) or confirmed partial response (PR) according to RECIST. CR: disappearance of all target and non-target lesions. PR: at least 30 % decrease in sum of the longest dimensions (LDs) of target lesion, taking as reference the baseline sum LD, associated to non-progressive disease response for non-target lesions. Confirmed responses are those that persist on repeat imaging study at least 4 weeks after initial documentation of response.

Blood specimens were analyzed at a sponsor-designated laboratory for analysis of shed proteins/receptors related to Human Epidermal Growth Factor Receptor (HER) signaling (epidermal growth factor receptor [EGFR], HER2). These measurements were determined by enzyme-linked immunosorbent assay (ELISA). The data for all Phase 1 participants was combined for this outcome.

Tumor tissue was analyzed at a sponsor-designated laboratory to investigate EGFR, KRAS and HER2 status (wild type or mutated). Participants who did not provide samples for central laboratory analysis confirmation were classified as "unknown". The data for all Phase 1 participants was combined for this outcome.

Data in "PF-00299804 45 mg" treatment arm at Cycle 0 Day -9 (C0D-9) represents participants from Phase 1 only and at C1D14 represents participants from both Phase 1 and Phase 2.

Data in "PF-00299804 45 mg" treatment arm at C0D-9 represents participants from Phase 1 only and at C1D14 represents participants from both Phase 1 and Phase 2.

Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.

AUC0-24: Area under the plasma concentration versus time curve from time zero (pre-dose) to 24 hours post dose. Data in "PF- 00299804 45 mg" treatment arm at C0D-9 represents participants from Phase 1 only and at C1D14 represents participants from both Phase 1 and Phase 2.

AUClast: Area under the plasma concentration versus time curve from time zero (pre-dose) to time of last quantifiable concentration.

AUCinf: Area under the plasma concentration versus time curve from time zero (pre-dose) to extrapolated infinite time (0 - ∞). It is obtained from AUC (0 - t) plus AUC (t - ∞).

Rac was calculated by dividing AUC0-24 (C1D14) by AUC0-24 (C0D-9).

Data in "PF-00299804 45 mg" treatment arm represents participants from both Phase 1 and Phase 2.

Rss was calculated by dividing AUC0-24 (C1D14) by AUCinf (C0D-9).

Data in "PF-00299804 45 mg" treatment arm represents participants from both Phase 1 and Phase 2.

EORTC QLQ-C30: included global health status/quality of life (QoL), functional (Fn) scales (physical, role, cognitive, emotional, and social), symptom scales (fatigue, pain, nausea/vomiting), and single items (dyspnea, appetite loss, insomnia, constipation, diarrhea, and financial difficulties). Scores were averaged, transformed to 0-100 scale; higher score for Global Qol/Fn scales=better level of QoL/functioning or higher score for symptom scales/items=greater degree of symptoms. Overall scale change is categorized as Improved (if average scales change from baseline: for Global QoL/Fn scales >=10; for symptom scale/item <=-10), Worsened (if average scales change from baseline: for Global QoL/Fn scales <=-10; for symptom scale/item >=10), and Stable (if average scales change from baseline >-10 but <10 for Global QoL/Fn scales and symptom scale/item) and participants in each category are reported.

EORTC QLQ-LC13 consisted of 13 questions relating to disease symptoms specific to lung cancer and treatment side effects typical of treatment with chemotherapy and radiotherapy. The 13 questions comprised 1 multi-item scale for dyspnea and 10 single-item symptoms and side effects (coughing, hemoptysis, sore mouth, dysphagia, peripheral neuropathy, alopecia, chest pain, arm pain, other pain, and medicine for pain). Scores averaged, transformed to 0-100 scale; higher symptom score = greater degree of symptoms. Overall scale change is categorized as Improved (if average scales change from baseline <=-10), Worsened (if average scales change from baseline >=10), and Stable (if average scales change from baseline >-10 but <10) and participants in each category are reported.

DLQI: 10-item questionnaire to measure how much the participant's skin problem has impacted their life over the previous week. All questions were answered on a 4-point Likert scale ranging from 0 (not at all/not relevant) to 3 (very much/prevented work or studying). The DLQI was calculated by summing the score of each question and ranged from 0 to 30, where higher scores indicate more quality of life impairment.

Number of participants with BOR according to RECIST: CR= disappearance of all target and non-target lesions. PR= at least 30% decrease in sum of LDs of target lesion, taking as reference baseline sum LD, associated to non-progressive disease response for non-target lesions. Stable/no response= neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD. Objective progression= at least a 20% increase in sum of LDs of target lesions, taking as reference the smallest sum of LD recorded since treatment started and/or unequivocal progression of existing non-target lesions and/or appearance of 1 or more new lesions.

Time in weeks from first documentation of objective tumor response to objective tumor progression or death due to any cause, whichever occurred first. Duration of tumor response was calculated as (the date of the first documentation of objective tumor progression or death due to any cause minus the date of the first CR or PR [which ever occurred first] that was subsequently confirmed plus 1) divided by 7. DR was calculated for the subgroup of participants with a confirmed objective tumor response.
