  • 1. Capable of understanding the written informed consent, provides signed and
  • witnessed written informed consent and agrees to comply with protocol
  • requirements.
  • 2. Aged at least 18 years at the time of signing informed consent.
  • 3. Has documented histologically confirmed diagnosis of advanced or metastatic
  • solid tumours.
  • 4.Meets at least one of the following PSMA-based eligibility criteria:
  • For patients with non-prostate cancer:
  • At least one of the following:
  • a. PSMA positivity by IHC in an FFPE sample obtained prior to the initiation of
  • study enrolment (defined as availability of a representative archived
  • pre-treatment tumour specimen for submission to central reader). Brushing, cell
  • pellet from ascites or pleural effusion or lavage samples are not acceptable.
  • Samples of bone lesion or samples that require a decalcification procedure are
  • acceptable.
  • b. PSMA positivity by IHC in a fresh tumour biopsy sample set in formalin
  • including decalcification of bone metastases (brushing, cell pellet from
  • pleural effusion or lavage samples are not acceptable) obtained prior to
  • initiation of study treatment for submission to central reader.
  • -Provision of fresh tumour samples is a preferable option even if FFPE is
  • available and site can submit both FFPE and fresh samples.
  • For patients with prostate cancer:
  • At least one of the following:
  • a.Documented PSMA+ lesion determined by local PSMA-PET scan obtained between
  • the last anti-cancer treatment and prior to commencing CB307 study treatment.
  • -Note that while a positive PSMA test result by IHC is not required for
  • eligibility if PSMAPET positive status is confirmed locally, provision of a
  • fresh tissue sample or archival tumour sample is still requested form
  • retrospective PSMA-IHC analysis on-study.
  • b.PSMA positivity by IHC in an FFPE newly obtained biopsy or archival sample
  • prior to the initiation of study enrolment. Brushing, cell pellet from ascites
  • or pleural effusion or lavage samples are not acceptable.
  • Samples of bone lesion or samples that require a decalcification procedure are
  • acceptable.
  • -Provision of fresh tumour samples is a preferable option even if FFPE is
  • available; sites may submit both FFPE and fresh samples.
  • 5. Has an Eastern Cooperative Oncology Group Performance Status 0 or1.
  • 6. Has adequate organ function.
  • For further information, please refer to the clinical protocol.

排除标准

  • - Has evidence of autoimmune or significant, uncontrolled concomitant diseases
  • that could affect compliance with the protocol or interpretation of results.
  • - Has discontinued from anti-cytotoxic lymphocyte-associated protein 4,
  • anti-PD1 or anti-PD-L1 antibody because of intolerable toxicity according to
  • the investigator*s assessment.
  • - Has brain metastasis including leptomeningeal metastasis or primary brain
  • - Has encephalitis, meningitis, or uncontrolled seizures in the year prior to
  • informed consent.
  • - Has current or history of CNS disease, such as stroke, epilepsy, CNS
  • vasculitis or a neurodegenerative disease.
  • - Has uncontrolled pleural effusion, pericardial effusion or ascites that
  • require regular recurrent drainage procedures.
  • - Is currently receiving bisphosphonate therapy for symptomatic hypercalcaemia.
  • - Has active second malignancy.
  • -Has significant cardiovascular/cerebrovascular vascular disease within 6
  • months prior to the first dose of CB307, including any of the following:
  • hypertensive
  • crisis/encephalopathy, uncontrolled hypertension (systolic >150 mm Hg and/or
  • diastolic >100 mm Hg), unstable angina, transient ischaemic attack/stroke,
  • congestive heart failure (NYHA III or greater), serious cardiac arrhythmia
  • requiring treatment (exceptions are atrial fibrillation, paroxysmal
  • supraventricular tachycardia), history of thromboembolic events (such as
  • myocardial infarction, stroke or pulmonary embolism).
  • - Has known HIV-1, HBV or HCV infection.
  • - Has known active or uncontrolled bacterial, viral, fungal, mycobacterial,
  • parasitic or other infection (excluding fungal infections of nail beds) or any
  • major episode of infection requiring treatment with IV antibiotics or
  • hospitalisation (relating to the completion of the course of antibiotics,
  • except if for tumour fever) within 28 days prior to the first dose of CB307.
  • - Has a history of chronic liver disease or evidence of hepatic cirrhosis.
  • - Has any other diseases, metabolic dysfunction, physical examination finding
  • or clinical laboratory finding that give reasonable suspicion of a disease or
  • condition that would contraindicate the use of an investigational drug or that
  • may affect the interpretation of the results or render the patient at high risk
  • from treatment complications, in the opinion of the investigator.
  • - Has had major surgery or significant traumatic injury within 28 days prior to
  • the first dose of CB307 (excluding biopsies) or anticipation of the need for
  • major surgery during study treatment or 3 months after the last dose.
  • - Administered a live attenuated vaccine within 28 days prior to the first dose
  • of CB307 or anticipation that such a live attenuated vaccine will be required
  • during the study or 3 months after the last dose.
  • - Has dementia or altered mental status that would prohibit informed consent.
  • - Has a known hypersensitivity to any of the components of CB307 or history of
  • severe hypersensitivity reactions to antibodies (NCI CTCAE v5.0 grade >=3).
  • - Adverse events (grade 1 or baseline) not recovered from previous anticancer
  • - Last dose with any of the following agents: etanercept, infliximab,
