Inclusion Criteria:

- M1A or B NSCLC with any number of prior therapies or any stage Small cell Lung Cancer
(SCLC) with any number of prior therapies

- Planned systemic therapy (i.e. intent to treat)

- Provision of written informed consent for biospecimen storage, broad genetic and
proteomic analysis of tumor and normal tissues, without restrictions, AND correlation
with outcome data

- Aged 18 years and over.

- Measurable or evaluable disease.

- ECOG performance status of 0-2 with expected survival of at least 3 months.

- Tumor specimens:

- Tumor specimens:

- 4.7.1 First Priority: availability of a minimum of a 1 X 10 mm core fresh frozen
tumor, or ≥3 mm diameter spherical pellet from a pleural effusion (≥50% tumor cells),
or ≥3 mm diameter spherical pellet from a fine needle aspirate (≥50% tumor cells)
from clinically indicated interventional procedures, with no systemic anti-cancer
therapy or radiation to all sites of evaluable disease between collection of the
biopsy and entry into the study (e.g. if a brain metastasis was radiated but the lung
tumor was not, then the latter could still be biopsied and the subject enrolled after
radiation therapy of the brain metastasis (and vice versa)).

or

- Second Priority: availability of paraffin-embedded tumor (via biopsies or pleural
effusions) at least 5 X 5 mm (3 X 3 mm for pleural effusions) cross-sectional tumor
area, with no systemic anti-cancer therapy or radiation to all sites of evaluable
disease between collection of the biopsy and entry into the study; the collection of
the paraffin-embedded tissues may have taken place up to 12 months prior to
enrollment in CASTLE.

- Willingness to undergo all study collection procedures and sample analyses including
prerequisite baseline molecular testing via ResponseDX: Lung (Response Genetics Inc.)
and VeriStrat (Biodesix) - see 6.3 below for details.

- Exclusion criteria

- Other co-existing malignancies except for basal cell carcinoma or cervical cancer in
situ.

- Compromise of patient diagnosis or staging if tissue is harvested for research
