Brief Summary:

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.

Condition or disease Intervention/treatment Phase
Advanced/ Metastatic Hepatocellular Carcinoma Drug: ASLAN001 Phase 1 Phase 2

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.

Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Phase 1b Open Label Dose Assessment Study of ASLAN001 (Varlitinib) in Patients With Advanced/ Metastatic Hepatocellular Carcinoma (HCC) With an Expansion Cohort in HCC Patients Expressing HER3 Who Have Progressed on First Line Sorafenib or Lenvatinib
Actual Study Start Date : May 5, 2017
Estimated Primary Completion Date : May 5, 2019
Estimated Study Completion Date : May 5, 2021

Arm Intervention/treatment
Experimental: ASLAN001
A 3+3 study de-escalating dose design will be employed for dose determination. Subjects will receive treatment in 21-day cycles until disease progression, intolerable toxicities or withdrawal of consent.
Drug: ASLAN001

Starting dose at 300mg BD Dose level +1: 400mg BD (which is the target dose for this study)

Dose reduction of ASLAN001 in event of adverse events grade 2 and above:

Dose level -1: 200mg BD Dose level -2: 100mg BD

Other Name: Varlitinib




Primary Outcome Measures :
  1. Definition of MTD (maximum tolerable dose) [ Time Frame: up to 1 year since the start of treatment ]
    The maximum tolerable dose is defined as the highest evaluated dose where < 1/6 patients experiences DLT during the DLT evaluation window.


Secondary Outcome Measures :
  1. Objective Response Rate [ Time Frame: up to 1 year since the start of treatment ]

    Defined as the proportion of patients with a response of Partial Response or Complete Response, as defined by RECIST v1.1 criteria.

    Measurable disease:

    Tumor lesions: Must be accurately measured in at least one dimension (longest diameter in the plane of measurement is to be recorded) with a minimum size of 10mm on CT scan Malignant lymph node: ≥15mm in short axis on CT scan Non-measurable disease: All other lesions, including small lesions (longest diameter <10mm or pathological lymph nodes with >10 to <15mm short axis) as well as truly non-measurable lesions


  2. Progression Free Survival [ Time Frame: up to 1 year since the start of treatment ]
    Defined as the time from the start of treatment until the date of objective disease progression or death (by any cause in the absence of progression). Progression is defined in accordance with RECIST v1.1 criteria.

Ages Eligible for Study:   21 Years to 99 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

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 the study but histological confirmation is mandatory prior to the start of study therapy.

    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.

  2. Patients must have failed Sorafenib or Lenvatinib due to disease progression or intolerance.
  3. Presence of radiographically measurable disease based on RECIST v1.1.
  4. No evidence of biliary duct obstruction, unless obstruction is controlled by local treatment or, in whom the biliary tree can be decompressed by endoscopic or percutaneous stenting with subsequent reduction in bilirubin to below 1.5 x upper level of normal (ULN).
  5. Patients age ≥ 21 years at the time of written informed consent.
  6. Patients with Eastern Cooperative Oncology Group (ECOG) performance status of 0-2.
  7. Patient must be able to understand and willing to sign the informed consent form and donate tumor tissue (archival or fresh) for evaluation of relevant exploratory endpoints.
  8. Patient with adequate organ and hematological function:

    a. Hematological function, as follows: i. Absolute neutrophil count (ANC) ≥ 1.5 x 109/L ii. Platelet count ≥ 80 x 10^9/L b. Renal functions, as follows: i.
