      P2.03a-039 - ABOUND.70+: Interim Quality of Life (QoL) Results of nab-Paclitaxel/Carboplatin Treatment of Elderly Patients With NSCLC (ID 4286)

      14:30 - 14:30  |  Author(s): M. Modiano

      • Abstract

      Background:
      QoL data in elderly patients with NSCLC receiving chemotherapy are limited, although these assessments can help inform treatment decisions. Interim QoL outcomes from the ongoing ABOUND.70+ study are reported here.

      Methods:
      Patients aged ≥ 70 years with locally advanced/metastatic NSCLC were randomized 1:1 to first-line nab-paclitaxel 100 mg/m[2] on days 1, 8, and 15 + carboplatin AUC 6 on day 1 every 21 days or the same nab-paclitaxel/carboplatin regimen with a 1-week break between cycles. The primary endpoint is the percentage of patients with grade ≥ 2 peripheral neuropathy or grade ≥ 3 myelosuppression adverse events. QoL (an exploratory endpoint) was assessed on day 1 of each cycle using the Lung Cancer Symptom Scale (LCSS) and EuroQoL-5 Dimensions-5 Levels (EQ-5D-5L).

      Results:
      This analysis included 119 patients; 88 patients (74%) completed baseline + ≥ 1 postbaseline QoL assessments. The median age was 76 years (range, 70-93 years); 30% of patients were ≥ 80 years of age, 56% were male, and 99% had an ECOG PS 0-1. In general, LCSS symptom burden index and average total scores improved during cycles 1-4. The LCSS item of cough improved each cycle, with a mean change of 18.98 mm from baseline to end of cycle 4 on the visual analog scale (VAS; 95% CI, 8.42-29.54 mm). Fifty percent of patients had a clinically meaningful improvement (≥ 10 mm [VAS]) from baseline in the composite LCSS pulmonary symptom items of cough, shortness of breath, and hemoptysis. More than 80% of patients maintained/improved in each EQ-5D-5L dimension from baseline; complete resolution of baseline pain/discomfort, anxiety/depression, and self-care items was reported by ≥ 55% of patients (Table). Figure 1



      Conclusion:
      Clinically meaningful improvements in several QoL dimensions were observed in elderly patients with NSCLC treated with nab-paclitaxel/carboplatin. These data support the role of nab-paclitaxel/carboplatin in this patient population. NCT02151149

      P2.06-011 - Phase 2 Study of MM-121 plus Chemotherapy vs. Chemotherapy Alone in Heregulin-Positive, Locally Advanced or Metastatic NSCLC (ID 4158)

      14:30 - 14:30  |  Author(s): M. Modiano

      • Abstract

      Background:
      The role of the HER3 receptor and its ligand heregulin (HRG) in the progression of multiple cancers has been well established. Seribantumab (MM-121) is a fully human, monoclonal IgG2 antibody that binds to the HRG domain of HER3, blocking HER3 activity. The correlation between the level of HRG mRNA in tumor tissue and progression free survival (PFS) were retrospectively analyzed in three completed randomized Phase 2 studies of seribantumab plus standard of care (SOC) versus SOC alone (NSCLC, breast cancer and ovarian cancer). In each of these studies, high levels of HRG mRNA predicted shortened PFS for patients who received SOC treatment, while the addition of seribantumab to SOC improved PFS for patients with HRG-positive (HRG+) tumors. This is consistent with the hypothesis that HRG expression defines a drug tolerant cancer cell phenotype shielded from the effects of cytotoxic or targeted therapies and that blockade of HRG-induced HER3 signaling by seribantumab counters the effects of HRG on cancer cells, with the potential to improve outcomes for HRG+ patients. It is estimated that up to approximately 50% of cases of all solid tumor indications are HRG+. This HRG expression may contribute to rapid clinical progression in a subset of patients with poor prognosis.

      Methods:
      In the ongoing randomized, open-label, international, Phase 2 study, NSCLC patients with HRG+ tumors are being prospectively selected using a HRG RNA in situ hybridization assay performed on a recent tumor tissue sample collected via fine needle aspiration, core needle biopsy or excision. Approximately 560 patients will be screened to support enrollment of 280 HRG+ patients, who will be randomized in a 2:1 ratio to receive seribantumab plus investigator’s choice of docetaxel or pemetrexed, or docetaxel or pemetrexed alone. Patients will be wild-type for EGFR and ALK and will have progressed following one to three systemic therapies, one of which must be an anti-PD-1 or anti-PD-L1 therapy, for locally advanced and/or metastatic disease. Overall survival (OS) is the primary endpoint of the study and secondary endpoints include PFS, objective response rate and time to progression. Safety and health-related quality of life will also be assessed. An interim analysis is planned when 50% of final OS events have been reported. Enrollment has been initiated with approximately 80 sites expected to participate worldwide. Clinical Trials Registry number: NCT02387216
