Brief summary: This is a Phase 1/2, open-label, multicentric, non-randomised, parallel-arm study that aims to establish the safety, tolerability, and initial efficacy of CAN04 in combination with 3 SoC chemotherapies (mFOLFOX, DTX, and G/C).


Eligibility criteria: Inclusion Criteria:

PHASE 1 and PHASE 2:

* Subject must be able to understand and sign written informed consent, according to local guidelines.
* Subject must be ≥18 years of age at the time of signature of the ICF.
* Subject must have an ECOG PS score of 0 or 1.
* Subject must have adequate organ function, as indicated by the laboratory values in the protocol
* Women of childbearing potential must have a negative serum pregnancy test before study entry. Women of non-childbearing potential will have had at least 24 continuous months of natural (spontaneous) amenorrhea, and an appropriate clinical profile (eg, age appropriate, history of vasomotor symptoms), or have had hysterectomy, bilateral salpingectomy or bilateral oophorectomy\>6 weeks before screening.
* Male or female subjects: Male subjects with female partners of childbearing potential and female subjects of childbearing potential are required to use 2 forms of acceptable contraception, including 1 barrier method, during their participation in the study and for 4 months after the last dose of CAN04 or for 6 months after the last dose of the relevant chemotherapies, whatever is longer. Male subjects must also refrain from donating sperm during their participation in the study and in the period when contraceptives are required
* Subjects must not have contraindications according to the approved local summary of product characteristics (SmPC) for the respective components of the SoC chemotherapies.

PHASE 1 (Dose Escalation)

* Subject has histologically or cytologically confirmed diagnosis of locally advanced cancer or metastatic cancer. Subjects do not need to have measurable disease per response evaluation criteria in solid tumours (RECIST) v1.1.
* Subject has a condition where all standard therapeutic options with proven survival benefit have been exhausted, refused by the subject, or are contraindicated. OR Subject has a condition where 1 of the 3 study regimens (mFOLFOX, DTX, or G/C) is considered SoC for the next-line treatment.
* Subject has additional disease characteristics per treatment arm:

  * mFOLFOX Arm: All subjects eligible for mFOLFOX can be enrolled. A maximum of 2 previous lines of cytotoxic chemotherapy treatment for metastatic disease is allowed (targeted agents without cytotoxic effect will not be counted).
  * DTX Arm: Subjects eligible to receive DTX as monotherapy for NSCLC can be enrolled in this treatment arm. No more than 2 lines of prior systemic anti-cancer therapies for the metastatic disease are allowed. Targeted therapy is not counted as prior therapy. Subjects who received DTX monotherapy in a prior line of therapy are not eligible.
  * G/C Arm: All subjects eligible for G/C can be enrolled (including first-line treatments).. Subjects with BTC will be prioritized.

PHASE 2 All treatment arms in Phase 2 (CRC, NSCLC or BTC)

* Subject must have at least 1 measurable lesion as defined by RECIST v1.1. Tumour lesions that have been irradiated ≥4 weeks before the start of treatment, and have subsequently had documented progression, may be chosen as target lesions in the absence of measurable lesions that have not been irradiated.
* Only applicable after the second interim analysis has been performed: Primary or metastatic lesion amenable to biopsy and willingness of the subject to undergo a screening (if no adequate archival tissue is available) and an on-treatment biopsy (as defined in the protocol). The lesion accessible for biopsy may not be the only target lesion and should not be located in a previously irradiated field (unless this index lesion has PD ≥20% after radiation). The requirement(s) for the screening and/or on-treatment biopsy and/or archival tissue may be waived by the sponsor for individual sites and subjects, in particular if tumour locations are not safely accessible, after discussion and documented agreement between the site and the sponsor´s medical monitor.

CRC Arm

* Subject has definitive histologically or cytologically confirmed metastatic or locally advanced adenocarcinoma of the colon or rectum without possibility of locoregional treatment with curative intention or candidate for curative metastasectomy
* Subject has received at least 2 prior lines of therapy for non-resectable locally advanced or metastatic CRC and has progressed or is intolerant to those therapies. If the tumour is microsatellite instability-high, it should have progressed on a previous immune CPI unless contraindicated, or such therapy is not available to the subject. Subjects with KRAS wildtype should be eligible to receive mFOLFOX and should have received anti-EGFR therapy unless contraindicated or not available for the subject.
* Note: For subjects who received adjuvant or neoadjuvant chemotherapy and had recurrence within 6 months of completion of the adjuvant or neoadjuvant chemotherapy, the adjuvant or neoadjuvant therapy is counted as the first line of chemotherapy for the metastatic disease.

NSCLC Arm

* Subject has histologically or cytologically confirmed squamous or non-squamous NSCLC unresectable stage IIIB/C or stage IV for whom monotherapy DTX treatment is indicated.
* Subject received platinum-based therapy and a programmed cell death protein 1 or programmed death-ligand 1 inhibitor as prior treatment regimens (unless contraindicated or such therapy is not available to the subject). Prior CPIs and chemotherapy may have been administered alone or in combination. No more than 2 prior lines of cytotoxic chemotherapy containing regimens for the advanced or metastatic disease are allowed.

Note: Subjects who received DTX monotherapy in a prior line of therapy are not eligible.

* Subjects who received adjuvant or neoadjuvant chemotherapy and had recurrence within 6 months of completion of the adjuvant or neoadjuvant chemotherapy are allowed to count the adjuvant or neoadjuvant therapy as the first line of chemotherapy for the recurrent/metastatic disease.
* Subject eligible for mutation-targeted therapies (eg, osimertinib, alectinib, crizotinib, larotrectinib, capmatinib, pralsetinib) must have exhausted treatment options for targeted therapies available locally

BTC Arm

* Subject has histopathological or cytological biliary tract carcinoma (intrahepatic or extrahepatic cholangiocarcinoma, gallbladder cancer, or ampullary carcinoma) non-resectable, recurrent, or metastatic amenable for G/C treatment indicated as SoC.
* Subject has not received standard systemic anti-cancer therapies neither for non-resectable locally advanced nor for metastatic disease.
