Inclusion criteria
Inclusion criteria: 1) Patients with histologically or cytologically confirmed advanced or metastatic solid malignancies that are known to express EGFR, or in which EGFR is thought to be a relevant therapeutic target, including but not limited to: colorectal, lung, gastric, esophageal, pancreatic, head and neck, breast, ovarian, cervical, urothelial, and renal cancers, and glioblastoma multiforme. 2) Patients must have been previously treated with one or more lines of anticancer therapy and have documented disease progression during or after their most recent line of anticancer therapy. In addition, either there is no further SOC therapy for the patient or the remaining SOC therapies are deemed not appropriate for the patient by the Investigator. 3) Voluntary provision and understanding of signed and dated, written informed consent prior to any mandatory study-specific procedures, sampling, or analysis 4) Male or female aged >=18 years on the day of signing informed consent 5) Eastern Cooperative Oncology Group (ECOG) Performance Score (PS) 0 or 1. 6) Adequate organ function within 14 days before first AFM24 infusion, as defined as in the protocol. Patients must also meet these criteria when assessed within 3 days before first AFM24 infusion to remain eligible. 7) Serum potassium, calcium, magnesium and phosphorus within normal limits. If values are low on the initial screening assessment, supplements may be given and values repeated to confirm within normal limits. 8) Patients must have at least one tumor site that is accessible to biopsy and that is considered by the Investigator to be low risk and of sufficient size to undergo a core biopsy procedure on at least 2 separate occasions. 9) Phase 2a only: Patients must have measurable disease per RECIST v1.1 (i.e., at least 1 measurable lesion >=10 mm by CT scan or MRI or >=20 mm by chest X ray, malignant lymph nodes are considered measurable if short axis is >=15 mm assessed by CT scan), with the last imaging performed within 28 days before Cycle (C) 1 Day (D) 1 (C1D1). 10) Patients in Phase 2a must have a disease history specific to their disease as listed below: • Colorectal Cancer: Patients with metastatic colorectal carcinoma (mCRC) whose disease has progressed following prior treatment with oxaliplatin, irinotecan and a fluoropyrimidine for metastatic disease. Patients must have documentation of RAS mutational status. If RAS is wildtype, prior therapy must have included an approved anti-EGFR monoclonal antibody, i.e., either cetuximab or panitumumab, as a component. For patients with microsatellite instability-high or mismatch repair deficient mCRC prior lines of therapy must have included a checkpoint inhibitor if approved and available. • NSCLC without a targetable EGFR mutation: Patients with advanced or metastatic NSCLC whose disease has progressed after having received >=2 prior lines of therapy for advanced disease, which must have included platinum-based therapy and an anti-PD-1/PD-L1 antibody. Patients must have documentation of NSCLC without a targetable EGFR mutation as assessed by genomic sequencing of tumor or circulating free tumor DNA. Patients with a targetable mutation other than EGFR must have received an approved targeted treatment if available. Patients with anaplastic lymphoma kinase (ALK)-positive tumor must have received an approved ALK inhibitor such as crizotinib, ceritinib, alectinib or lorlatinib. Patients with ROS proto-oncogene 1 receptor tyrosine kinase (R

Exclusion criteria: 1) Currently participating in a study and receiving study therapy, or participated in a study of an investigational agent and received study therapy or used an investigational device within 4 weeks of the first dose of study treatment. 2) Treatment with systemic anticancer therapy within 4 weeks (6 weeks if therapy was mitomycin C and/or nitrosoureas), or within 5 half-lives of the agent if half-life is known and it is shorter, before first dose of study drug. Anticancer therapies include cytotoxic chemotherapy, targeted inhibitors, and immunotherapies, but do not include hormonal therapy or radiotherapy. 3) Radiation therapy within 2 weeks before first dose of study drug or unresolved (National Cancer Institute [NCI] Common Terminology Criteria for Adverse Events [CTCAE] v5.0 >Grade 1) toxicity from previous radiotherapy (e.g., radiation dermatitis). 4) Major surgery within 4 weeks before first dose of study drug. 5) Previous treatment related toxicity, with the exception of alopecia (any grade), or peripheral neuropathy or fatigue which have not recovered to CTCAE v5.0 =470 msec obtained as the mean from 3 consecutive resting electrocardiograms (ECGs) using the Fridericia’s formula; Clinically important abnormalities in rhythm, conduction, or morphology of resting ECG (e.g., complete left bundle branch block or third-degree heart block); Congenital long QT syndrome; Uncontrolled hypertension (>=130/80 mmHg based on accurate measurement and average of >=2 readings which are >=5 minutes apart on >=2 occasions at least one day apart). 8) Stroke or transient ischemic attack within 6 months prior to screening. 9) History of leptomeningeal disease or spinal cord compression. 10) Known brain metastases unless asymptomatic and not requiring steroids for at least 4 weeks prior to start of study treatment. 11) Patients with primary brain tumor who require high dose steroids (defined as=30 mg prednisolone or equivalent per day) or who received high dose steroids within 4 weeks prior to first dose of study treatment. 12) Diagnosis of immunodeficiency or active infection including known hepatitis B, hepatitis C, or human immunodeficiency virus (HIV). 13) Active autoimmune disease that requires systemic treatment with steroids or other immunosuppressive agents, or patients who have received such agents within 1 months prior to first dose of study treatment. Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency) is not considered a form of systemic treatment. 14) Patients who require systemic steroid treatment or any other immunosuppressive therapy, or patients who received such therapy within 4 weeks prior to the first dose of study treatment, with the exception of steroid allowance for primary brain tumor as outlined in exclusion criterion 11,

| Primary end point(s): PHASE 1: The incidence of dose limiting toxicities (DLTs), AEs, and serious AEs (SAEs), dose interruption, and changes between baseline and post-baseline laboratory parameters including electrocardiograms (ECGs), vital signs, and physical exams PHASE 2a: Overall response rate (CR+PR) assessed by local RECIST v1.1.;Timepoint(s) of evaluation of this end point: PHASE 1: For cohorts 1&2, at least 2 patients, and for cohorts 3+, at least 3 patients, need to be evaluable for the dose-determining set. Patients must receive >=80% of their assigned AFM24 dose in Cycle 1 and complete the 28-day DLT observation period or have had a DLT within the first cycle of treatment to be considered evaluable for DLT. Safety will be assessed by periodic vital signs, physical examinations, ECOG PS, 12-lead ECGs, clinical laboratory assessments, and monitoring of adverse events (AEs). PHASE 2a: Tumor assessment with CT and/or MRI will occur at Screening as well as during the last week of Cycles 2, 4, 6, 8, and every 3 cycles thereafter. Partial or complete response needs to be confirmed with repeated assessment at least 4 weeks after the initial assessment.;Main Objective: PHASE 1: Determine the maximum tolerated dose (MTD), select a recommended phase 2 dose (RP2D), and investigate the safety and tolerability of AFM24 in patients with advanced solid malignancies. PHASE 2a: Assess the preliminary anti-tumor efficacy of AFM24, using tumor response criteria as defined by local RECIST v1.1;Secondary Objective: PHASE 1: Characterize the pharmacokinetics (PK) of AFM24 administered intravenously (i.v.); Characterize the immunogenicity of AFM24; and assess the preliminary anti-tumor efficacy of AFM24, using tumor response criteria as defined by: Local Response Evaluation Criteria in Solid Tumors (RECIST) v1.1, Local immune-related RECIST (iRECIST), Central RECIST v1.1, Central iRECIST PHASE 2a: Characterize the safety and tolerability of AFM24, including both acute an | — |
