Participants will be included in Part C of the study only if they satisfy all the following criteria:
1. Must have given written informed consent, before any study-related activities are carried out and must be able to understand the full nature and purpose of the trial, including possible risks and adverse effects.
2. Male or female, aged greater than or equal to 18 years, inclusive at Screening.
3. Have moderate-to-severe CIPN as defined by a NRS score of greater than or equal to 4 and less than or equal to 8 on a 0 – 10 scale for the participant’s experience of all CIPN-related symptoms.
4. Completion of chemotherapy between 1 to 6 months prior to screening.
5. Participant is otherwise medically healthy (in the opinion of the Investigator [or delegate]), as determined by pre-study medical history and without clinically significant abnormalities including:
a. Physical examination without any additional clinically relevant findings
b. Heart rate in the range of 40 to 100 beats/minute after 5 minutes rest in supine or semi-supine position.
c. Body temperature (tympanic), between 35.5°C and 37.7°C.
d. Electrocardiogram without clinically significant abnormal findings including QT interval corrected for Fredericia (QTcF) < 450 msec for male subjects and < 470 msec for female subjects.
e. No clinically significant findings in serum chemistry, haematology, or urinalysis.
6. Female participants must be of non-childbearing potential i.e., surgically sterilised (hysterectomy, bilateral salpingectomy, bilateral oophorectomy at least 6 weeks before the screening visit) or postmenopausal (where postmenopausal is defined as no menses for 12 months without an alternative medical cause and a FSH level consistent with postmenopausal status, per local laboratory guidelines), or, if of childbearing potential:
a. Must have a negative serum pregnancy test at the screening visit and a negative urine pregnancy test on Day -1, prior to dose administration.
b. Must agree not to donate ova or attempt to become pregnant from the time of signing consent until at least 30 days after the last dose of study drug.
c. If not exclusively in a same-sex relationship, must agree to use adequate contraception (which is defined as use of a condom by the male partner combined with use of a highly effective method of contraception from one month prior to screening until at least 30 days after the last dose of study drug.
7. Male participants must:
a. Agree not to donate sperm from the time of signing consent until 90 days after the last dose of study drug.
b. If engaging in sexual intercourse with a female partner who could become pregnant, agree to use adequate contraception (defined as use of a condom plus a highly effective method of contraception) from the time of signing consent until at least 90 days after the last dose of study drug.
c. If engaging in sexual intercourse with a female partner who is not of childbearing potential or a same-sex partner, agree to use a condom from the time of signing consent until at least 90 days after the last dose of study drug.
8. Negative alcohol breath test at Screening or pre-dose on Day 1.
9. Negative urine drugs of abuse test at Screening or pre-dose on Day 1.
10. Willing and able to comply with all scheduled visits, treatment plans, laboratory tests and other study procedures.
Participants will be excluded from Part C of the study if there is evidence of any of the following:
1. Current, active infection that requires systemically absorbed antibiotic, antifungal, antiparasitic or antiviral medications.
2. Suffers from frequent or recurrent infections (defined as greater than or equal to 3 recurrent or separate occurrences in the 12 months preceding first study drug administration or 2 recurrent or separate occurrences in the 6 months preceding first study drug administration).
3. Use of antioxidant-containing medications, supplements or products within 30 days prior to the first study drug administration.
4. Use of systemic corticosteroid, sulindac, or any other nonsteroidal anti-inflammatory drugs (NSAID) within 7 days or 5 half-lives of the medication (whichever is longer) prior to the first study drug administration.
5. Use of tricyclics, serotonin and norepinephrine reuptake inhibitors (SNRIs), sodium channel blockers, and gabapentinoids within 30 days or 5 half-lives of the medication (whichever is longer) prior to first study drug administration.
6. Use of selective serotonin reuptake inhibitors (SSRIs) (citalopram, escitalopram, sertraline, etc.) within 30 days prior to the first study drug administration.
Note: Participant on stable doses of SSRIs is permitted.
7. Experienced myocardial infarction or undergone coronary artery bypass grafting within 6 months of Screening.
8. Diagnosed with congestive heart failure, defined as New York Heart Association (NYHA) Class II-IV.
9. History of hypersensitivity reaction, anaphylaxis or other clinically significant reactions or known allergy to any of the study drug ingredients (including any of its metabolic derivatives – sulindac, sulindac sulfone and sulindac sulfide), or any other NSAIDs.
10. History of or currently existing aspirin-induced asthma, gastric ulcers, non-iatrogenic intestinal perforation, or GI bleeding from NSAID usage for which intervention was required.
11. History of any clinically significant disorder (which, in the opinion of the Investigator [or delegate] would make implementation of the protocol or interpretation of study results difficult, or that would put the subject at risk by participating in the study), including cardiovascular, haematologic, pulmonary, hepatic, renal, gastrointestinal (GI), connective tissue, uncontrolled endocrine/metabolic (including but not limited to diabetes), neurologic, and psychiatric, or any disorder that may prevent the successful completion of the study or influence the absorption, distribution, metabolism, excretion, or action of the study drug (including any of its metabolic derivatives – sulindac, sulindac sulfone and sulindac sulfide).
Note: Participants with history of resolved childhood asthma, history of migraine (if less than or equal to 1 monthly episode and not on preventative medication), or history of non-hospitalised depression (if not on any anti-depressant) will be allowed to participate in the study.
12. Uncontrolled hypertension defined by systolic blood pressure (BP) > 180 mmHg or diastolic BP > 110 mmHg after 5 minutes in supine or semi-supine position.
13. History of surgery within 12 weeks prior to Screening, or surgery planned during the study.
14. Current diagnosis of tumour or metastasis affecting the cervical/lumbosacral plexus and evidence of tumour-associated pain.
15. Currently receiving chemotherapy for the treatment of neoplasia.
