Brief summary

The purpose of this multicenter, open label trial (NAPISTAR 1-01) is to evaluate the safety/tolerability, pharmacokinetics and preliminary efficacy of TUB-040 and to find the best dose of TUB-040 in participants with ovarian cancer and Non Small Cell Lung Cancer. TUB-040 is an antibody-drug-conjugate which delivers a topoisomerase I inhibitor to tumor cells which overexpress the target NaPi2b. The study consists of three parts: In dose escalation, ovarian cancer participants and lung cancer participants receive increasing doses of TUB-040 until the maximal tolerated dose is found. In dose optimization, at least two doses are compared with each other to determine which dose is optimal for participants. In dose expansion, a single dose will be used in a larger number of participants. TUB-040 is given IV every 3 weeks until the disease progresses or the participants has to stop due to side effects.

Interventions

A complete treatment cycle is defined as 21 calendar days. TUB-040 will be administered as an intravenous (IV) solution on day 1 of each treatment cycle

Radiologically measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 as assessed by the INV. 6. Eastern Cooperative Oncology Group (ECOG) 0-1. 7. Have a life expectancy of more than 12 weeks for disease-related mortality, as evaluated by the INV. 8. Participants must be willing to sign an archival tissue release form for research purposes and determination of biomarker expression. 9. Participants must be willing to undergo a non-contrast high resolution computed tomography (HRCT) of the thorax scan and pulmonary function testing (PFT) at screening. 10. Adequate organ function 11. Resolution of all acute toxic effects of prior therapy or surgical procedures to ≤grade 1 (except alopecia, hyperpigmentation, or discoloration (incl. vitiligo) of the skin and nails, stable immune-related toxicity such as hypothyroidism on hormone replacement, adrenal insufficiency on ≤10 mg daily prednisone \[or equivalent\], chronic grade 2 peripheral sensory neuropathy after prior taxane therapy or anticancer treatment such as but not limited to IOs). 12. Participants of childbearing potential (FCBP) who are sexually active with a non-sterilized partner must use at least one highly effective method of contraception from the time of screening and must agree to continue using such precautions until the end of exposure, plus 5 half-lives and 6 months add-on in the case of participants assigned female at birth. 13. In the opinion of the investigator, the participant must be able to understand, give written informed consent, and comply with all study-related procedures, medication use, and evaluations. 14. The participant must not have a history of non-compliance with medical regimens or be considered potentially unreliable and/or uncooperative. 15. The participant must be willing to sign and date the informed consent form (ICF) Key

Exclusion criteria

(for all phases) 1. The participant is pregnant, lactating or breastfeeding or has a positive serum pregnancy test during the screening period. 2. History of hypersensitivity to exatecan or excipients of the TUB-040 formulation. 3. Participants are not allowed to participate in interventional clinical studies either concurrently or within the previous 28 days or within 5 half-lives of any investigational pharmacologic agents or imaging materials, including dyes, investigational surgical techniques, or devices. 4. Participants with spinal cord compression or active central nervous system disease, and/or carcinomatous meningitis. 5. Prior radiotherapy \<2 weeks from trial inclusion. 6. Major surgery within 21 days prior to signing the ICF, unless the participant is recovered at that time. 7.

Active, uncontrolled or severe impairment of the urogenital, renal, hepatobiliary, cardiovascular, gastrointestinal, neurologic, or hematopoietic systems which, in the opinion of the investigator, would predispose the participant to the development of complications from the administration of protocol therapy. 13. History of another malignancy with ongoing treatment or not yet free from disease for 2 years, except for appropriately treated carcinoma in situ of the cervix, non-melanoma skin carcinoma, or other malignancy with a similar expected curative outcome. 14. Documented other concurrent non-malignant comorbidities such as unstable or uncontrolled pectoral angina, myocardial infarction during the last 6 months, valvular heart disease that requires treatment, acute myocarditis, or congestive heart failure (CHF) (New York Heart Association III or IV). 15.

Participants with a history of HCV infection are eligible if HCV viral load is undetectable at screening. 3.
