Cohort A (NSCLC): In addition to the core inclusion criteria, each subject in Cohort A must also meet the following inclusion criteria to be enrolled: 5.Histological or cytological diagnosis of NSCLC. 6.Tumour negative for EGFR mutation and ALK translocation. 7.One prior line of a platinum-doublet regimen that was given for at least 2 cycles and that did not contain a PD-(L)1 or any other health authority approved or experimental immune modulating agent. 8.Have measurable disease per RECIST v1.1. Cohort B (NSCLC WOO): In addition to the core inclusion criteria, each subject in Part B must meet the following inclusion criteria: 9.Histological or cytological diagnosis of NSCLC. 10.Tumour negative for EGFR mutation and ALK translocation. 11.Subjects must have adequate lung function to permit surgical resection. 12.At least 1 measurable lesion as per RECIST v1.1. Cohort C (DLBCL): In addition to the core inclusion criteria, each subject must meet the following inclusion criteria: 13.Histologically confirmed diagnosis of DLBCL with relapsed and/or refractory disease. 14.Received at least two systemic regimens for the treatment of DLBCL. One therapy line must have included a CD20-targeted therapy and one therapy line must have included CAR-T cell therapy where this is the institution´s standard of care, unless contraindicated. 15.At least one bi-dimensionally, PET positive, measurable disease site by spiral CT scan defined as a lesion that measures at least =15 mm in the LD and =10 mm in the SAD at baseline as defined by Lugano classification.

Exclusion criteria

Exclusion criteria: Core Exclusion Criteria Subjects are excluded from the study if any of the following criteria apply: 1.Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti-PD-L2 agent or with an agent directed to another stimulatory or co-inhibitory T-cell receptor. 2.Has received prior systemic anti-cancer therapy including investigational agents within 28 days prior to treatment. 3.Has received prior radiotherapy within 2 weeks of start of study treatment. Subjects must have recovered from all radiation-related toxicities, not require corticosteroids, and not have had radiation pneumonitis. A 1-week washout is permitted for palliative radiation to non-CNS disease. 4.Has a known additional malignancy that is progressing or has required active treatment within the past 3 years. 5.Has known active CNS metastases and/or carcinomatous meningitis. 6. Has an active autoimmune disease that has required systemic treatment in past 2 years. 7. Has a history of (non-infectious) pneumonitis / interstitial lung disease that required steroids or has current pneumonitis / interstitial lung disease. 8. Has a history of prior severe or life-threatening infusion related reaction or skin adverse reaction related to previous treatment with other immune stimulatory anticancer agents. Exclusion Criteria Cohort A (NSCLC): 8. Receipt of greater than 1 line of treatment with chemotherapy for Stage IIIB/IIIC/IV disease. 9. Has received radiation therapy to the lung that is >30 Gy within 6 months of the first dose of trial treatment. Exclusion Criteria Cohort B (NSCLC WOO): 10. Administration of chemotherapy or any other anti-cancer therapy (including radiotherapy) in the pre-operative period. Exclusion Criteria Cohort C: DLBCL: 11.Known history of “double or triple hit” genetics or cytogenetic abnormalities involving chromosomal rearrangements of c-MYC, BCL-2 and BCL-6 genes. 12.Subjects that have undergone ASCT within the period =3 months prior to signing the ICF. 13.Subjects that have received an infusion of CAR T cells within 60 days prior to the planned date of dosing with FS118. For further information, please refer to the clinical protocol.

Design outcomes

Primary

MeasureTime frame
Main Objective: Cohort A (NSCLC ): To assess the efficacy of FS118 in terms of radiological response in all subjects; Cohort B (NSCLC WOO): To evaluate changes in specific T cell density (cells/mm2) in tumour samples collected pre- and post-treatment with FS118. Cohort C (DLBCL): To assess the efficacy of FS118 in terms of radiological response. ;Secondary Objective: Cohort A (NSCLC ): To assess the efficacy of FS118 in all subjects by alternative endpoints; To assess PK parameters for FS118; Assessment of the safety and tolerability of FS118; Cohort B (NSCLC WOO): Assessment of MPR to pre-operative FS118 therapy in resected tumour and lymph nodes; Assessment of radiographic response to pre-operative FS118 therapy; To assess the safety and tolerability of FS118 given in a pre-operative setting; To assess PK parameters for FS118; To evaluate soluble receptors (LAG-3 and PD-L1) following pre-operative FS118 therapy; Cohort C (DLBCL): To assess the efficacy of FS118 in all subjects by alternative endpoints; To assess PK parameters for FS118; Assessment of the safety and tolerability of FS118.;Primary end point(s): Cohort A Efficacy Endpoints: Overall response rate (ORR) as per RECIST v1.1. Cohort B Biomarker/Pharmacodynamic Markers Endopoints: Change in tumour infiltrating T cells subtypes in response to FS118. Cohort C Efficacy Endpoints: ORR as per the Lugano Classification.;Timepoint(s) of evaluation of this end point: Throughout the study duration at the study visits.

Secondary

MeasureTime frame
Timepoint(s) of evaluation of this end point: Throughout the study duration.;Secondary end point(s): Cohort A Efficacy Endpoints: •Assessments of antitumor activity include DCR, DoR, DoC, and PFS/iPFS as assessed by RECIST v1.1 and iRECIST. •OS.
