Phase 1b of ASLAN001 (Varlitinib) in Patients With Advanced/ Metastatic Hepatocellular Carcinoma (HCC)

NCT03499626

Description:

This is a single-arm, allocation open label study. Phase 1 is a dose-finding phase in patients with advanced/ metastatic hepatocellular carcinoma (HCC) who have progressed on first line Sorafenib or Lenvatinib. The primary objective of this study will be to establish the maximal tolerable dose (MTD) of ASLAN001 (Varlitinib) in the study population The secondary objectives include: 1. To evaluate the efficacy of ASLAN001 (Varlitinib), as measured by duration of response (DoR), progression free survival (PFS), overall survival (OS) and disease control rate (DCR) 2. To assess the ORR, DoR, PFS, DCR and OS by tumor EGFR/HER2/HER3/HER4 status 3. To identify tumor and host biomarkers predictive of treatment response or toxicity to ASLAN001.

Purpose

This is a single-arm, allocation open label study. Phase 1 is a dose-finding phase in patients with advanced/ metastatic hepatocellular carcinoma (HCC) who have progressed on first line Sorafenib or Lenvatinib. The primary objective of this study will be to establish the maximal tolerable dose (MTD) of ASLAN001 (Varlitinib) in the study population The secondary objectives include: 1. To evaluate the efficacy of ASLAN001 (Varlitinib), as measured by duration of response (DoR), progression free survival (PFS), overall survival (OS) and disease control rate (DCR) 2. To assess the ORR, DoR, PFS, DCR and OS by tumor EGFR/HER2/HER3/HER4 status 3. To identify tumor and host biomarkers predictive of treatment response or toxicity to ASLAN001.

Detailed Description

      -  There are currently no effective and approved second line treatment options for
           advanced/ metastatic HCC.

        -  ASLAN001 (Varlitinib) is a small molecule tyrosine kinase inhibitor against HER1 (EGFR),
           HER2, and HER4.

        -  In vivo studies on HER2/3 expressing HCC PDX models suggest inhibition of pERB B2/3,
           pERK1 and pERK 2 with treatment with ASLAN001 (Varlitinib). Dose dependent inhibition of
           Cdc2 and pAKT in HCC PDX models treated with ASLAN001 (Varlitinib) also suggest robust
           inhibition of the PI3K pathway.

        -  EGFR overexpression in HCC and matched non tumor tissues were detected in (32.5%) and
           (28.6%), respectively. Moreover, missense and silent mutations were detected in (39.4%)
           and (33.3%) of HCC tissues, respectively.

        -  Determine the maximum tolerable dose (MTD) of ASLAN001 (Varlitinib) in
           advanced/metastatic HCC patients.

        -  After the recommended dose is determined, the Phase Ib portion of the study will
           evaluate the efficacy of ASLAN001 (Varlitinib) in HCC patients who have progressed on
           Sorafenib.

        Inclusion Criteria:

          1. Patient must have unresectable or metastatic HCC with Childs Pugh status A with
             histologic confirmation.

             i) Subjects with only a radiologic diagnosis of HCC may be enrolled for screening in

             ii) Evaluable tumor tissue (formalin-fixed, paraffin embedded archival or recent
             acquisition) must have 15 unstained slides for correlative studies. If archived
             samples are not available, subjects must consent to a pre-treatment fresh biopsy as a
             condition of protocol participation.
