Clinical Trial Summary

This is a study to look at whether the presence of circulating tumour DNA (ctDNA) in the blood can help to predict whether giving adjuvant treatment after surgery can decrease the chance of the cancer coming back in people with lung cancer.

Description:

For people who have early stage non-small cell lung cancer (NSCLC), the usual treatment is surgery. For many people, surgery is enough to get rid of all the cancer. However, for some people, there may be a little bit of cancer remaining. If there is some cancer left over, it may lead to the cancer regrowing. This is called relapse. Many cancers shed little bits of their DNA (deoxyribonucleic acid, molecules that contain instructions for how cells develop and function) into the bloodstream. A blood test can be used to test for the amount of circulating tumour DNA (ctDNA). Some studies have shown that the presence of ctDNA in the blood may predict cancer recurrence. The purpose of this research study is to see if adjuvant treatment (additional treatment given after primary treatment) can help decrease the risk of the cancer recurring in people with lung cancer who have ctDNA detected in their blood after surgery.

Recruitment information / eligibility

• Status: Recruiting
• Enrollment: 66
• Est. completion date: December 1, 2026
• Est. primary completion date: August 1, 2025
• Accepts healthy volunteers: No
• Gender: All
• Age group: 18 Years and older

Eligibility

Inclusion Criteria:

1. Age = 18 years at the time of screening

2. Written informed consent obtained from the subject prior to performing any protocol-related procedures

3. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1

4. Weight = 35 kg

5. Must have a life expectancy of at least 24 months

6. Complete surgical resection of T1-2N0M0 NSCLC or T3/T4 multifocal NSCLC

7. Any pathologic subtype of NSCLC is eligible, including adenocarcinoma and squamous carcinoma. Patients with targetable genomic alterations without approved or available targeted adjuvant therapy options are eligible

8. Patients with detectable plasma ctDNA before or after complete surgical resection are eligible (RaDaR TM assay, Inivata Morrisville, North Carolina, USA).

9. No prior chemotherapy or radiotherapy is allowed for the current diagnosis of resected NSCLC.

10. Adequate organ and marrow function as defined in Table 4 (3.1.1)

11. Females of childbearing potential who are sexually active with a non-sterilized male partner must use at least one highly effective method of contraception from screening to 180 days after the final dose of study treatment. A serum pregnancy test within 72 hours prior to the initiation of therapy will be required for women of childbearing potential. It is strongly recommended for the male partner of a female subject to also use male condom plus spermicide throughout this period

12. Non-sterilized male subjects who are sexually active with a female partner of childbearing potential must use a male condom with spermicide from screening to 180 days after receipt of the final dose of study treatment. It is strongly recommended for the female partner of a male subject to also use a highly effective method of contraception throughout this period. In addition, male subjects must refrain from sperm donation while on study and for 180 days after the final dose of study treatment. 4.1.2 Exclusion Criteria

1. Participants that should receive adjuvant chemotherapy per standard of care (resected N1 or N2 disease, primary tumour >=4 cm).

2. Receipt of any conventional or investigational anticancer therapy within 21 days or radiotherapy within 14 days prior to the scheduled first dose of study treatment;

3. Prior receipt of any immune-mediated anti-cancer therapy including, but not limited to, anti-CTLA-4, anti-PD-1, anti-PD-L1 antibodies including nivolumab and agents targeting CD73, CD39, or adenosine receptors;

4. Incomplete surgical resection;

5. Concurrent enrolment in another therapeutic clinical study of systemic anti-cancer treatment. Enrolment in observational or supportive studies will be allowed;

6. Subjects with a recent history of myocardial infarction, congestive heart failure = Class 3 based on New York Heart Association Functional Classification or stroke within the past 3 months prior to the scheduled first dose of study treatment;

7. Active autoimmune disorders within the past 3 years prior to the scheduled first dose

of study treatment. The following are exceptions to this criterion:

1. Subjects with vitiligo or alopecia.

2. Subjects with hypothyroidism (e.g., following Hashimoto syndrome) not requiring systemic treatment or stable on hormone replacement.

3. Subjects with psoriasis not requiring systemic treatment.

4. Any chronic skin condition that does not require systemic therapy.

5. Subjects with celiac disease controlled by diet alone;

8. Have known uncontrolled human immunodeficiency virus (HIV)-1/2 infection.

• Participants with HIV (known HIV 1/2 antibodies positive) are allowed if all of the following conditions are met: CD4+ T-cell counts =350 cells/uL; no opportunistic infection within the past 12 months; on established anti-retroviral therapy for at least 4 weeks; and an HIV viral load less than 400 copies/mL.

9. History of primary immunodeficiency, solid organ transplantation, or active tuberculosis (by clinical evaluation that includes clinical history, physical examination and radiographic findings, and TB testing in line with local practice). In settings where there is clinical or radiographic evidence of tuberculosis, active disease must be excluded prior to enrolment. Subjects who have had adequately treated tuberculosis may be enrolled upon discussion with the coordinating Principal Investigator.

10. Other invasive malignancy within 2 years. Non-invasive malignancies (i.e., cervical carcinoma in situ, in situ prostate cancer, non-melanomatous carcinoma of the skin, ductal carcinoma in situ of the breast that has been surgically cured) are permitted.

11. Known allergy or hypersensitivity to investigational product formulations.

12. History of more than one event of infusion related reactions (IRR) requiring permanent discontinuation of IV drug treatment.

13. Uncontrolled intercurrent illness including, but not limited to ongoing or active infection requiring antibiotic therapy, uncontrolled hypertension, bleeding diatheses, or psychiatric illness/social situations that would limit compliance with study requirements, substantially increase risk of incurring AEs, or compromise the ability of the subject to give written informed consent.

14. Current or prior use of immunosuppressive medication within 14 days prior to the scheduled first dose of study treatment. The following are exceptions to this

criterion:

1. Intranasal, topical, inhaled corticosteroids or local steroid injections (e.g., intra articular injection).

2. Systemic corticosteroids at physiologic doses not to exceed 10 mg/day of prednisone or equivalent.

3. Steroids as premedication for hypersensitivity reactions (e.g., computed tomography [CT] scan premedication).

15. Receipt of live, attenuated vaccine within 30 days prior to the scheduled first dose of study treatment (Note: Subjects, if enrolled, should not receive live vaccine during the study and 180 days after the last dose of study treatment). Vaccination with an inactivated vaccine is permitted at any time.

16. Major surgery (as defined by the investigator) within 28 days prior to the scheduled first dose of study treatment or still recovering from prior surgery. Local procedures (e.g., placement of a systemic port, core needle biopsy, etc) are allowed without needing to wait for the 28-day recovery period.

17. Females who are pregnant, lactating, or intend to become pregnant during their participation in the study.

18. Subjects who are involuntarily incarcerated or are unable to willingly provide consent or are unable to comply with the protocol procedures. Any condition that, in the opinion of the investigator, would interfere with safe administration or evaluation of the investigational products or interpretation of subject safety or study results

19. Any condition that, in the opinion of the investigator, would interfere with safe administration or evaluation of the investigational products or interpretation of subject safety or study results.

20. History of allergic reactions attributed to compounds of similar chemical or biologic composition to Nivolumab or other agents used in the study.
