Who can take part

You may be able to join if

  • Provide signed and dated informed consent. For Part A only: signed pre-screening consent for participants that undergo pre-screening procedures or collection of historical data prior to informed consent procedure.
  • Life expectancy > 3 months as assessed by the Investigator.
  • Adequate organ function: a. Bone marrow function: hemoglobin ≥ 9.0 g/dL (equal to 5.59 mmol/L); platelet count ≥ 100 × 10^9 /L; leukocyte count ≥ 2.5 × 10^9 /L. b. Hepatic function: AST and ALT ≤ 2 × upper limit of normal (ULN) (3 × ULN in the case of liver metastases); bilirubin ≤ 1.5 × ULN (2 × ULN in case of liver metastases/participants with Gilbert’s disease). c. Renal function: serum creatinine < 1.5 × ULN and/or creatinine clearance ≥ 50 ml/min. d. Coagulation: no evidence for clinically relevant hypo- or hypercoagulability or presence of thrombosis/thrombotic event as per D-Dimer, antithrombin III (ATIII), prothrombin time (PT)/international normalized ratio (INR), and activated partial thromboplastin time (aPTT) analysis and treating physician’s assessment. Note: D-Dimer elevation by itself does not preclude inclusion if no clinical evidence of thrombosis is present.
  • All toxicities related to prior radiotherapy, chemotherapy, and any type of immunotherapy or other anti-cancer therapy, or surgical procedure must have recovered to Grade ≤ 1 based on NCICTCAE v5.0, except alopecia (any grade), and Grade 2 peripheral sensory neuropathy, and AEs that are clinically not considered as significant in this context and/or are stable on supportive therapy.
  • If participant has type II diabetes and receives metformin, metformin has to be replaced with other antidiabetic(s) prior to start of trial treatment (at minimum 7 days prior to trial baseline GDF-15 measurement at C1D1 prior trial IMP administration) and for the whole trial treatment duration
  • Women of childbearing potential must have a negative serum pregnancy test within 7 days prior to CTL-002 treatment. If a pregnancy test is not performed within 7 days of dosing with CTL-002, a repeat test must be performed prior to Day 1 dosing. Women of childbearing potential are defined as sexually mature women without prior hysterectomy or who have had any evidence of menses in the past 12 months. However, women who have been amenorrheic for 12 or more months are still considered to be of childbearing potential if the amenorrhea is possibly due to prior chemotherapy, anti-estrogens, or ovarian suppression.

  • Women of childbearing potential must have a negative serum pregnancy test within 7 days prior to CTL-002 treatment. If a pregnancy test is not performed within 7 days of dosing with CTL-002, a repeat test must be performed prior to Day 1 dosing. Women of childbearing potential are defined as sexually mature women without prior hysterectomy or who have had any evidence of menses in the past 12 months. However, women who have been amenorrheic for 12 or more months are still considered to be of childbearing potential if the amenorrhea is possibly due to prior chemotherapy, anti-estrogens, or ovarian suppression.
  • All participants, male and female, who are not surgically sterilized or postmenopausal as defined above, and participants’ partners of childbearing potential must agree to use “highly effective methods of contraception” during the trial and for at least 5 months (5 times the predicted half-life of CTL-002 in humans) after the last dose of CTL-002. “Highly effective methods of contraception” are combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation, progestogen-only hormonal contraception associated with inhibition of ovulation, intrauterine device, intrauterine hormone-releasing system, bilateral tubal occlusion, vasectomized partner, or sexual abstinence. The double-barrier method (synthetic condoms, diaphragm, or cervical cap with spermicidal foam, cream or gel), periodic abstinence (such as calendar, symptothermal, or post-ovulation), withdrawal (coitus interruptus), lactational amenorrhea method and spermicide only are NOT acceptable as “highly effective methods of contraception.”
  • Male or female aged ≥ 18 years.
  • Participants with histologically or cytologically confirmed/documented diagnosis of advancedstage, relapsed/refractory solid tumors in non-curable state as per current clinical knowledge (specific for Germany: who have exhausted all available approved standard treatments or are not eligible for them anymore)
  • For Part A (Phase 1), participants must have received during their prior treatment at least one antiPD-1/PD-L1 treatment (alone or in combination) and progressed on or relapsed after completion of the anti-PD-1/PD-L1 treatment (with a minimum of 12 weeks of anti-PD1/PD-L1 exposure). (1) For Part B (Phase 2a), participants must either have bladder cancer, hepatocellular cancer, nonsmall cell lung cancer or melanoma (for melanoma, only cutaneous and mucosal forms, not uveal/ocular) (approved anti-PD-1/PD-L1 indications) that relapsed on or were primary refractory to prior anti-PD-1/PD-L1 therapy with an approved anti-PD-1/PD-L1 compound (with a minimum of 12 weeks of anti-PD-1/PD-L1 exposure) (specific for Germany: and have exhausted all available approved standard treatments or are not eligible for them anymore). (2) colorectal cancer (MSS/mismatch-repair competent) and have not received any prior anti-PD1/PD-L1 therapy (Not applicable in Germany) (3) biomarker cohort with mixed solid tumors (”basket” cohort;) that relapsed on or were primary refractory to prior anti-PD1/PD-L1 therapy with an approved anti-PD-1/PD-L1 compound and that have exhausted available approved therapies for their disease or do not qualify for them anymore (specific for Germany: and have exhausted all available approved standard treatments or are not eligible for them anymore). Note: All Participants in cohorts (1) and (3) must have received an approved anti-PD-1/PD-L1 compound with a minimum of 12 weeks of anti-PD1/PD L1 exposure. Non-approved, experimental anti-PD-1/PD-L1 treatments are not permissive for enrolment (does not apply for cohort (2))
  • Ability to understand the purpose of the trial, provide signed and dated informed consent prior to performing any protocol-related procedures (including Screening evaluations), and able to comply with the trial procedures and any locally required authorization.
  • For Part A, ideally ~50% of participants enrolled per dose level should have increased GDF-15 serum levels (based on pre-screening result or historic serum GDF-15 data [up to 2 months prior to the start of treatment with CTL-002 where available]).
  • All participants must have biopsy-accessible tumor lesions and be willing to undergo tumor biopsy: triple-sequential biopsies (Part A) or dual-sequential biopsies (Part A backfill); in Part B, baseline biopsy (new or archived if obtained within 120 days prior to treatment start) from all participants. In the melanoma and the biomarker cohort with mixed solid tumors (“basket” cohort), an additional on-treatment biopsy is mandatory. All biopsies are mandatory unless not seen as safe and feasible by the treating physician or another specific reason that precludes a biopsy sample being taken and which should be discussed with the Medical Monitor prior to Screening or if applying to the sequential biopsy, prior to that biopsy. All other trial eligibility criteria must be met before the baseline biopsy sample is obtained. Important note for the biomarker [“basket”] cohort: in case biopsy cannot be taken for medical reasons and no archived biopsy <120 days is available, participant cannot be included, as biopsy is mandatory in this cohort for biomarker-correlation reasons). Note: Aspiration cytology is not acceptable as biopsy technique
  • For Part B, presence of radiologically measurable disease at baseline – with at least 1 lesion, not previously irradiated, that can be accurately measured at baseline as ≥ 10 mm in the longest diameter with computed tomography (CT) or magnetic resonance imaging (MRI) and is suitable for accurate, repeated measurements as per RECIST V1.1/iRECIST is required. This shall not be the lesion that is going to be biopsied
  • ECOG performance status 0-1.
