The therapeutic cancer vaccine, PDC*lung01 will be administered at two dose levels (low dose (LD) and high dose (HD)), as single agent or during maintenance treatment by pemetrexed (for adenocarcinomas in Cohorts A1 and A2) or added to the SoC (cohorts B1 and B2) i.e. anti-PD-1.
In cohorts A1 (low dose cohort) and A2 (high dose cohort), NSCLC patients will be treated at each of the six PDC*lung01 treatment visits with low dose/high dose administered successively by subcutaneous and then by intravenous route.
In cohort B1 and B2, the first PDC*lung01 injection will start within 48 hours after the first infusion of anti-PD-1. The fourth PDC*lung01 injection will occur within 48 hours after the infusion of the second cycle of anti-PD-1.
For each patient, the study will be divided into three consecutive parts:
- Pre-screening (for HLA-A*02:01 positivity), only patients with positive HLA-A*02:01 status will be proposed to be screened.
- Active period comprising a screening period, a treatment period (visits V1 to V6, during which the patient receives PDC*lung01 vaccine, at each visit) and an end-of-treatment (EoT) visit (V7, 4 weeks after the last injection),
- Follow-up period which starts after the EoT visit and lasts up to two years after the first IMP administration.

Inclusion criteria:
Pre-screening:
Documented HLA-A*02:01 positivity after the patient has provided written informed consent.
Only patients showing a documented positive result in pre-screening will be allowed to enter the screening period.
Screening:
-
Patients with histologically proven, or cytologically proven (allowed only for patients recruited in cohorts A1/A2), non-small-cell lung cancer (NSCLC). The stage of the disease is evaluated according to the classification of the American Joint Committee on Cancer, 8th edition (see Section 25.1)
a. For the dose-escalation phase (Cohorts A1 and A2): a wash-out period of at least 4 weeks after administration of the last cycle of platinum-based chemotherapy is required.
(i) Stage IIa/IIb/IIIa NSCLC following surgery and, if applicable, following adjuvant platinum-based chemotherapy, or (ii) Stage IV histologically or cytologically confirmed case of epidermoid (squamous) NSCLC following 4 courses of platinum-based therapy, if targeted treatment options were not indicated or (iii) Stage IV histologically or cytologically confirmed case of adenocarcinoma (non-squamous) lung cancer NSCLC following 4 to 6 courses cycles of pemetrexed and platinum combination if targeted treatment options were not indicated, (iv) Populations (ii) and (iii) who have stopped prematurely chemotherapy, after at least 2 cycles of platinum-based therapy, for any reason, AND do present with a documented stable disease or complete response.
b. For the anti-PD-1 immunotherapy (Cohorts B1 and B2): The patient has first-line metastatic stage IV NSCLC measurable disease and is starting anti-PD-1. The intention and decision to prescribe the anti-PD-1 monotherapy as SoC (TPS≥50%), assuming no targeted mutation detected, following standard NGS testing, if applicable, and thus no targeted treatment option is indicated, must have been made by the investigator before and regardless of the patient's participation in the study.

For female patients receiving Pemetrexed in cohorts A1/A2 concomitantly with PDC*lung01, according to corresponding SmPC, it is required to use effective contraception during treatment with pemetrexed.
For female patients receiving Pembrolizumab in cohorts B1/B2 concomitantly with PDC*lung01, according to corresponding SmPC, it is required to use an effective method of contraception up to 4 months thereafter.
A woman is considered of childbearing potential (WOCBP), i.e. fertile, following menarche and until becoming post-menopausal unless permanently sterile. Permanent sterilisation methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy.
A postmenopausal state is defined as no menses for 12 months without an alternative medical cause.
"Highly effective" contraceptive measures acceptable for the whole duration of the study have been defined based on the CTFGs recommendations on contraception and are the following:

- Abstinence or absence of sexual relations with men.
-
Males with reproductive potential should use barrier method of contraception (condom) from signing informed consent form (screening) up to at least 28 days after the last dose of PDC*lung01.
For male patients receiving Pemetrexed in cohorts A1/A2 concomitantly with PDC*lung01, according to corresponding SmPC, it is required to use barrier method of contraception up to 6 months thereafter.
