SCREENING:
• Male or female, age 18 years and above.
• Histologically or cytologically diagnosed unresectable Stage IIIb or Stage IV
NSCLC. Measurable disease is not an indispensable requirement for
enrollment/leukapheresis.
• ECOG performance status 0-1.
• Life expectancy of at least 3 months.
• Left ventricular ejection fraction >=50% or as per institution*s guidelines.
• Adequate venous access for leukapheresis.
• Participant is positive for any of the following alleles: HLA-A*02:01, HLA
A*02:05, HLA-A*02:06.
• Tumor tissue (archival biopsy) obtained at any time from the initial
diagnosis to time of study entry is mandatory for tumor antigen expression
analysis (NY-ESO-1 and/or LAGE1a). In case an archival biopsy is not available
a fresh biopsy may be considered in consultation with the sponsor.
LEUKAPHERESIS:
• Successfully completed screening: HLA-A*02:01, HLA-A*02:05 and/or HLA-A*02:06
positive and meeting the threshold for expression of NY-ESO-1 and/or LAGE1a.
• Suitable for leukapheresis, including the laboratory parameters mentioned in
chapter 5.1.2, item 12 of the protocol.
• Time point of leukapheresis the treatment scheme: see chapter 5.1.2, item 13
of the protocol for details.
CHEMOTHERAPY/TREATMENT:
• Must have received or are receiving at least 1 line of prior systemic
therapy. See chapter 5.1.3, item 15 of the protocol for details.
• Following treatment with a PD-1/PD-L1 checkpoint blockade therapy
administered either as monotherapy or in combination with other checkpoint
inhibitors or other therapies, progression is defined by meeting all of the
criteria defined in chapter 5.1.3, item 15b of the protocol.
• Histologically or cytologically diagnosed unresectable Stage IIIb or Stage IV
NSCLC with measurable disease per RECIST v1.1.
• Prior radiotherapy: For prior chest radiotherapy see D5a (exclusion criteria)
for details. Allowed in case of prior palliative or stereotactic radiosurgery
to solitary lesions outside of the chest.
• Acceptance of CNS metastases: see chapter 5.1.3, item 19 of the protocol for
details.
• Acceptance of initiation of the chemotherapy: see chapter 5.1.3, item 20 of
the protocol for details.
• Acceptance of standard of care line of therapy between leukapheresis and
treatment: see chapter 5.1.3, item 21 of the protocol for details.
• Contraception guidelines for males and females should be followed, see
chapter 5.1.3, item 23 and 5.3.3 of the protocol for details.
• Pembrolizumab treatment (rescue) for Arm A: see chapter 5.1.4 of the protocol
for details.

shorter). See chapter 5.2.2, item 15 of the protocol for details.
• Radiotherapy that involves the lung or >25% bone marrow exposure, or mean
heart dose >20Gy within 3 months. See chapter 5.2.2, item 19 of the protocol
for details.
