P1.01-070 - BIW-8962, an Anti-GM2 Ganglioside Monoclonal Antibody, in Advanced/Recurrent Lung Cancer: A Phase I/II Study (ID 10421)
09:30 - 16:00 | Presenting Author(s): Joo-Hang Kim
- Abstract
Background:
GM2 ganglioside is a tumor-associated antigen that is overexpressed in a high proportion of several malignancies, e.g. SCLC, NSCLC, mesothelioma, melanoma, neuroblastoma, multiple myeloma. BIW-8962 is a recombinant, humanized, non-fucosylated immunoglobulin G1 monoclonal antibody to GM2 ganglioside that shows pre-clinical activity towards lung cancer cell lines and in an animal model bearing SCLC xenografts. The aim of this study was to determine the safety and preliminary clinical efficacy of BIW-8962 administered as monotherapy in patients with previously treated lung cancer.
Method:
In phase I, patients (N=16) with advanced, recurrent lung cancer (8 each with SCLC and NSCLC) received increasing doses of BIW-8962 (1–10 mg/kg) intravenously every 3 weeks using a standard 3+3 design to determine the maximum tolerated dose (MTD). The highest dose (10 mg/kg) was administered to patients with advanced, recurrent SCLC (N=21) in phase II.
Result:
It was only possible to obtain pre-study biopsy samples for two patients, both of which showed cell surface GM2 overexpression of moderate intensity on immunohistochemistry testing. In phase I and II, all patients received the total planned dose. There were no dose-limiting toxicities in phase I and the MTD was not established. BIW-8982 10 mg/kg therefore used as the recommended phase II dose. The phase II study was prematurely terminated due to lack of efficacy. The objective response rate was 5.0% (95% CI, 0.1%–24.9%) in the efficacy evaluable population (N=20). Median overall survival was 304.0 days (95% CI, 70.0–406 days) and median progression free survival (PFS) was 43.0 days (95% CI, 38.0–43.0 days). One patient showed a durable partial response with PFS of 463 days and response duration of 382 days. There were a few patients with stable disease, which was generally not durable. No pattern of consistent toxicity was observed across the phases: there were no treatment-related adverse events (AEs) Grade ≥3, serious AEs, AEs leading to discontinuation of BIW-8962, or deaths. No unexpected trends or safety concerns were identified from laboratory parameter, vital sign, or electrocardiogram assessments. Anti-BIW-8962 antibodies were not detected in serum of any patient before or following treatment. Exploratory analysis of circulating tumor cells and other potentially predictive or pharmacodynamic markers did not reveal any results consistent with an effect from BIW-8962.
Conclusion:
This study was prematurely terminated due to lack of efficacy, for which the reason is unknown. Clinical development of BIW-8962 has been discontinued.

P1.04-001 - Osimertinib with Ramucirumab or Necitumumab in Advanced T790M-positive EGFR-Mutant NSCLC: Preliminary Ph1 Study Results (ID 7940)
09:30 - 16:00 | Author(s): Joo-Hang Kim
- Abstract
Background:
Combination studies of a first- or second-generation EGFR tyrosine kinase inhibitor (TKI) and either a VEGF or EGFR-targeting monoclonal antibody have recently shown promising clinical results in EGFR-mutant non-small cell lung cancer (NSCLC) patients. The preliminary safety results from the phase 1 study JVDL (NCT02789345), combining third-generation EGFR TKI osimertinib (Osi) with human IgG1 monoclonal antibodies ramucirumab (Ram) or necitumumab (Neci), are reported.
Method:
Eligible pts naïve to third-generation EGFR TKI therapy with advanced EGFR T790M-positive NSCLC who progressed after initial EGFR TKI therapy were enrolled. In the dose-finding portion, following a dose de-escalation 3+3 design, patients received daily oral Osi (80 mg) and either 10 mg/kg intravenous (IV) Ram on day 1 (D1) every two weeks (Q2W), or 800 mg (IV) Neci on D1 and D8 Q3W. Primary objective of the study is to assess the safety and tolerability of Ram or Neci combined with Osi, and secondary objectives include preliminary evaluation of efficacy.
Result:
As of data cutoff on 09-May-2017, 7 pts were treated in the completed dose-finding portion: 3 pts with Ram+Osi (Arm A) and 4 pts (1 non-evaluable and replaced) with Neci+Osi (Arm B). No DLTs were observed in either arm, and the initial dose level became the recommended dose for expansion cohort. After the DLT observation period was complete, the only Grade ≥3 (Gr≥3) treatment-related adverse event (TRAE) was dermatitis acneiform (Arm B), with one unrelated Gr≥3 treatment-emergent AE (TEAE) of increased lipase (Arm B) and one serious AE of Gr2 diverticulitis (unrelated to study treatment) (Arm A). Expansion cohort A of Ram+Osi is fully enrolled with 22 pts. Safety data were available for 18 out of 22 cohort A patients. Gr≥3 TEAEs were reported in 4 patients, including dyspnea (unrelated [n=1]), decreased appetite (unrelated [n=1]), and hypertension (related [n=2]). Three patients reported serious adverse events (none related to study treatment): Gr3 dyspnea and Gr2 pyrexia, Gr2 dyspnea, and Gr2 urinary tract infection. No death was reported in patients in the dose-finding portion, and one death unrelated to study treatment was reported in the expansion cohort.
Conclusion:
No DLTs were observed and no unexpected safety signals were seen to date. The recommended dose for expansion cohort was the initial dose level of 10 mg/kg ramucirumab IV Q2W with oral 80 mg osimertinib. Additional safety and efficacy observation for the combination of Ram+Osi is ongoing, and will be presented at the meeting.
