A Phase II Multi Center Study of BGB324 in Combination With Pembrolizumab in Patients With Previously Treated Advanced Adenocarcinoma of the Lung

This is an open-label, multi-center, single arm, phase II study to assess the anti-tumor
activity and safety of bemcentinib when given in combination with pembrolizumab in up to 77
patients with previously treated, advanced adenocarcinoma of the lung. The study will enroll
two cohorts of patients with previously treated, advanced adenocarcinoma of the lung: Cohort
A will consist of patients who received a maximum of 1 prior line of platinum-containing
chemotherapy and no prior immunotherapy of any kind. Cohort B will consist of patients with a
maximum of 2 prior lines whereas the most recent line must have included a PD-(L)1 inhibitor.
The primary objective is objective response rate.

Inclusion Criteria:

1. Provision of signed informed consent.

2. Male and non-pregnant females who are aged 18 years or older at the time of provision
of informed consent.

3. Histopathologically or cytologically documented Stage IV adenocarcinoma non-small cell
lung cancer (NSCLC). Note: Patients with a mixed histology including a significant
area of adenocarcinoma histology are eligible.

4. Cohort A only: Has disease progression on or after a prior platinum-containing
chemotherapy. Note: Patients with Epidermal growth factor receptor (EGFR) mutations or
ALK genomic rearrangements must have documented disease progression on at least one
licensed therapy for these indications and may not have received platinum-containing

5. Cohort B only:

1. Has received a maximum of two prior lines of therapy in the advanced setting,
with the most recent treatment regimen containing an anti-PD-(L)1-therapy (as
monotherapy or in combination).

2. Must have had disease control (SD, PR or CR) for at least 6 months on most recent
treatment containing at least 2 doses of anti-PD-(L)1-therapy.

3. Has disease progression when entering screening and this must be within 12 weeks
of last dose of most recent treatment containing an anti-PD-(L)1 therapy.
Progression should have been confirmed in one of the following ways: (i) Having
had two scan assessments completed at least 4 weeks apart, both showing
progression according to RECIST 1.1 or (ii) having had one scan assessment
completed showing disease progression according to standards used for previous
therapy combined with rapid disease progression / clinical progression.

6. Measurable disease as defined by RECIST 1.1 on computed tomography (CT) or magnetic
resonance imaging (MRI) and as determined by the site study team. Tumor lesions
situated in a previously irradiated area are considered measurable if progression has
been demonstrated in such lesions.

7. Provision of suitable tumor tissue for the analysis of Axl kinase expression and PD-L1
expression. Suitable tumor tissue must consist of a minimum of newly acquired (fresh)
tumor tissue sample (as a FFPE block), together with either further newly acquired
tumor tissue (i.e. further FFPE block) or an archival tumor tissue sample (as a
further FFPE block or further 10 unstained slides). See Section 5.3.13 for further

and Activated Partial Thromboplastin Time (aPTT) ≤1.5 times the ULN. Note: If
patient is receiving anticoagulant therapy, then PT or Partial thromboplastin
time (PTT) must be within therapeutic range of intended use of anticoagulants;

12. Patients (both male and female) of reproductive potential must be willing to practice
highly effective methods of contraception throughout the study and for 120 days after
the last dose of study medication. Abstinence is acceptable if this is the usual
