Plain-language summary
This is a Phase 1, multicenter, open-label, dose escalation and dose expansion study to evaluate the safety, tolerability, pharmacokinetics, and preliminary evidence of antitumor activity of CPO-100 administered intravenously in cycles of 3 weekly doses with 1 week rest (1 cycle = 4 weeks) in adult patients with advanced solid tumors.

Inclusion criteria
. Presence of a pathologically documented (histology or cytology) locally advanced or metastatic solid tumor cancer.
. Patients has failed at least 2 lines of conventional systemic therapy or have no other standard of care therapies available for their cancer. Prostate cancer patients should have received adenosine triphosphate (ADT) alone,(GnRH agonist, GnRH antagonist, or surgical orchiectomy and a pathway targeted agent such as abiraterone, enzalutamide, etc (castration-resistant prostate cancer). M1 disease must be present (not just biochemical recurrence).
. Male or female patients18 years of age or older.
. ECOG (Eastern Cooperative Oncology Group) performance status (PS) of 0, 1 or 2
. Having at least one measurable target lesion present and documented by RECIST 1.1 for each cancer other than prostate cancer. Patients with prostate cancer may be enrolled with non-measurable disease providing the patient with a prostate-specific antigen (PSA) increase that is ≥25% and ≥2 ng/mL above the nadir, which is confirmed by a second value ≥3 weeks later, or 2 or more new bone lesions on imaging.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Part A-1: Number of subjects with Dose Limiting Toxicities (DLTs)
Timeframe: At the end of cycle 1 (each cycle is 28 days)
2
Part A-2: Number of subjects with Dose Limiting Toxicities (DLTs) when prophylactic use of G-CSF is allowed during Cycle 1
Timeframe: At the end of cycle 1 (each cycle is 28 days)
3
Part B: Dose Expansion - Incidence and severity of Adverse Events
. Most recent chemotherapy ≤14 days or have residual NCI CTCAE greater than Grade 1 chemotherapy-related side effects, with the exception of alopecia.
. Use of any experimental drug ≤28 days or 5 half-lives (whichever is shorter) prior to the first dose of CPO-100. For study drugs for which 5 half-lives is ≤28 days, a minimum of 14 days between termination of the study drug and administration of CPO-100 is required.
. Wide field radiotherapy (including therapeutic radioisotopes such as strontium 89 and lutetium 177) administered ≤28 days or limited field radiation for palliation ≤7 days prior to starting study drug or has not recovered from side effects of such therapy.
. Major surgical procedures ≤28 days of beginning study drug, or minor surgical procedures ≤7 days. No waiting required following port-a-cath placement.
. Previously untreated brain metastases. Patients who have received radiation or surgery for brain metastases are eligible if therapy was completed at least 2 weeks previously and there is no evidence of central nervous system disease progression, and no requirement for chronic corticosteroid therapy.
. Leptomeningeal metastases or spinal cord compression due to disease.
. Known serious hypersensitivity reactions to docetaxel or life-threatening toxicity due to prior exposure to docetaxel
