CRITÈRES D'ÉLIGIBILITÉ (EN)
  • Ability to understand and the willingness to sign a written informed consent. A signed informed consent must be obtained before any study-specific procedures are performed.
  • Male or female patients aged ≥ 18 years

  • Dose Escalation

    Dose Expansion Cohort A: Participants with histologically-confirmed advanced breast, NSCLC, SCLC, colorectal, and bladder cancers who have failed at least one prior therapy and/or are not eligible for therapies expected to provide clinical benefit.

    Cohort B: Participants with histologically-confirmed R/R B-cell lymphomas that are expected to express CD20 including DLBCL, HGBL, FL (grades 1-3a), FL (grade 3b), MCL, and Burkitt lymphoma who have failed at least two prior therapies and/or are not eligible for therapies expected to provide clinical benefit. Transformed large B-cell lymphoma patients are eligible. FL patients should meet criteria for requiring treatment.

    • Participants with histologically-confirmed advanced solid tumor who have failed at least one prior therapy and/or are not eligible for therapies expected to provide clinical benefit.
    • Histologically-confirmed B-cell lymphomas that are expected to express CD20 including DLBCL, HGBL, FL (grades 1 to 3b), MCL, and Burkitt lymphoma who have failed at least two prior therapies and/or are not eligible for therapies expected to provide clinical benefit (including autologous stem cell transplantation). Transformed large B-cell lymphoma patients are eligible. FL patients should meet criteria for requiring treatment.
  • Patients must have evaluable or measurable disease (as per Response Evaluation Criteria in Solid Tumors, version 1.1 [RECIST 1.1], or the Lugano lymphoma classification.
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1 (Appendix A).
  • Life expectancy of at least 12 weeks

  • Patients must have adequate bone marrow function as assessed by the following laboratory tests to be conducted within 7 (±3) days before the first dose of study drug:

    • Hemoglobin ≥ 85 g/L
    • Absolute neutrophil count (ANC) ≥ 1.5 x 109/L
    • Platelet count ≥ 100 x 109/L for Dose Escalation and ≥ 75 x 109/L for Dose Expansion NOTE: For Dose Expansion, patient who do not meet the above hematological criteria, because of bone marrow suppression from prior therapies and/or extensive tumour involvement in the marrow, may be considered for enrollment in the trial after consultation with the Medical Monitor.

  • Patients must have adequate liver function as assessed by the following laboratory tests to be conducted within 7 (±3) days before the first dose of study drug:

    • Total bilirubin ≤ 1.5 times the upper limit of normal (ULN)
    • Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 3 times ULN or ≤ 5 times ULN for patients with malignant liver involvement
  • Patients must have adequate kidney function, as assessed by the estimated glomerular filtration rate (eGFR) >50 mL/min within 7 (±3) days before the first dose of study drug (eGFR to be calculated by the Cockcroft-Gault formula) or creatinine ≤ 1.5 times the ULN

  • Patients must have adequate coagulation, as assessed by the following laboratory tests to be conducted within 7 (±3) days before the first dose of study drug:

    • Prothrombin time/International normalized ratio (PT/INR) ≤ 1.5 for patients not on anticoagulation
    • Activated partial thromboplastin time (aPTT) ≤ 1.5 times ULN for patients not on anticoagulation Note: Patients on anticoagulation with an agent such as heparin (eg. enoxaparin, dalteparin, etc.) will be allowed to participate if no prior evidence of underlying abnormality in coagulation parameters exists.
  • Adequate cardiac function per institutional normal measured by echocardiography or multigated acquisition (MUGA) scan (LVEF ≥ 50%)

  • Women of childbearing potential must have a negative serum beta human chorionic gonadotropin (β-HCG) pregnancy test obtained within 7 (±3) days before the start of administration of study drug.

    Note: A woman is of childbearing potential, i.e. fertile, following menarche and until becoming postmenopausal unless permanently sterile. Permanent sterilization methods include but are not limited to hysterectomy, bilateral salpingectomy and bilateral oophorectomy. A postmenopausal state is defined as no menses for 12 months without an alternative medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a postmenopausal state in women not using hormonal contraception or hormonal replacement therapy.

  • Women of childbearing potential and fertile men must agree to use adequate contraception when sexually active from signing of the informed consent form for the full study until at least 6 months after the last study drug administration. Patients must agree to utilize 2 reliable and acceptable methods of contraception simultaneously. A man is considered fertile after puberty unless permanently sterile by bilateral orchiectomy. Men being treated with PCLX-001 are advised not to father a child during and up to 6 months after treatment; prior to treatment, advice should be sought for conserving sperm due to the chance of irreversible infertility as a consequence of treatment with PCLX-001. Female partners of childbearing potential from male study participants have to use adequate contraception / birth control between signing of the informed consent and 6 months after the last administration of the study drug if the male study participant is not sterilized.
  • The investigator or a designated associate is requested to advise the patient how to achieve highly effective birth control. Highly effective (failure rate of less than 1% per year) contraception methods, when used consistently and correctly, include:
  • Combined (estrogen and progestin containing: oral, intravaginal transdermal and progestin-only (oral, injectable, implantable) hormonal contraception associated with inhibition of ovulation.
  • Intra-uterine device (IUD) or intrauterine hormone-releasing system (IUS).
  • Bilateral tubal occlusion or vasectomized partner (provided that partner is the sole sexual partner and has received medical assessment of the surgical success).
  • Sexual abstinence (reliability to be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient).
  • Male patients with a female partner of reproductive potential must use a condom and ensure that an additional form of contraception is also used during treatment and until 6 months after last study drug administration. Patients must agree to utilize reliable and acceptable methods of contraception simultaneously
