( ≥ 1+) and NRG1 expression on the cell surface of the tumor (either
on archival tumor or fresh tumor biopsy) using analytically validated
assays by central laboratory.

and have disease progression on or after last prior treatment (based
on RECIST v1.1).
- Subjects with locoregional recurrences amenable to definite surgery or
additional radiation are excluded.
For Group 4: Subjects with previously treated, unresectable stage III
or IV NSCLC with documented HER3 expression ( ≥1+) and NRG1
expression on the cell surface of the tumor (either on archival tumor
or fresh tumor biopsy) using analytically validated assays by central
laboratory.
- Subjects must have no more than 3 prior lines of systemic regimens
and have disease progression on or after last prior treatment (based
on RECIST v1.1).
For further information please view Protocol P64.

E.4 | Principal exclusion criteria |
1. Subjects with leptomeningeal or brain metastases or spinal cord compression.
- Subjects with untreated brain or meningeal metastases are not eligible
(computed tomography [CT] scans are not required to rule this out
unless there is a clinical suspicion of central nervous system [CNS]
disease).
- Subjects with treated and radiologic or clinical evidence of stable brain
metastases (confirmed by 2 scans at least 4 weeks apart), with no
evidence of cavitation or hemorrhage in the brain lesion are eligible
providing that they are asymptomatic and do not require
corticosteroids. Subjects are not permitted to receive enzyme inducing
anti-epileptic drugs.
2. Prior HER3- directed treatment (HER2- or EGFR-directed treatment is
acceptable).
3. Use of an investigational anti-cancer drug within 28 days (or 5 half
-lives, whichever is longer) preceding the first dose of GSK2849330
OR chemotherapy within the last 3 weeks (6 weeks for prior
nitrosourea or mitomycin C) OR any major surgery, radiotherapy, immunotherapy or any other anti-cancer therapy within the last
4 weeks, except as noted above.
4. Unresolved toxicity greater than NCI-CTCAE, version 4.0 [NCI, 2009]
Grade 1from previous anti-cancer therapy except alopecia and stable
anemia (i.e.,untransfused Hb ≥9.0 g/dL without the need for supportive transfusion within 2 weeks of screening) at the time of treatment
allocation.
5. Known or suspected hypersensitivity reaction to prior biologic
therapy (e.g., therapeutic monoclonal antibody) that in the opinion
of the investigator is a contraindication to their participation in
the study.
6. Current use of a prohibited medication or requires any of these medications
during treatment (protocol Section 10.2).
7. History or evidence of significant cardiovascular risk including any of
the following:
- LVEF <50%
-A QT interval corrected for HR (QTc) ≥ 480 msec (≥500 msec for subjects
with bundle branch block)
- History or evidence of current clinically significant uncontrolled
arrhythmias.
Exception: Subjects with controlled atrial fibrillation for >30 days
prior to enrollment are eligible.
- History of acute coronary syndromes (including myocardial infarction
and unstable angina), coronary angioplasty, or stenting within 6 months
prior to enrollment.

or hepatitis C virus (HCV) infection (with the exception of chronic or
cleared HBV and HCV infection which will be allowed).
9. Evidence of another active malignancy (excludes non-melanoma skin cancer). Consult GSK Medical Monitor if unsure whether second
malignancies meet requirements specified above.
10. Psychological, familial, sociological, or geographical conditions
that do not permit compliance with the protocol.
11. Concurrent medical condition that in the investigator’s opinion
would jeopardize compliance with the protocol.
