Brief summary

This is a multi-center, first-in-human, open label, dose escalation (Part A) and expansion (Part B) Phase 1 study in subjects with advanced solid tumors and in subjects with solid tumors with selected genetic alterations that are either direct (YES1 amplification) or dependent (Hippo Pathway alterations) targets of NXP900.

Interventions

Inclusion criteria

Part A Inclusion Criteria: 1. Provide written informed consent. 2. 18 years old or older. 3. Advanced, metastatic, and/or progressive solid tumors for whom there is no authorized or effective therapy available, or for whom such therapies are considered inappropriate by the Investigator. 4. Measurable disease according to Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1. 5. Eastern Cooperative Oncology Group (ECOG) performance status of 0-1.

Exclusion criteria

1. Subjects with known human epidermal growth factor receptor 2 (HER2+) overexpressing malignancies. 2. Radiotherapy (except for palliative reasons), endocrine therapy, chemotherapy, or investigational agent within 28 days, (42 days for nitrosoureas, mitomycin-C) of first dose of NXP900. Subjects can continue to receive bisphosphonates due to metastatic bone disease or GnRH agonists if they have prostate cancer. 3. Ongoing toxic manifestations of previous treatments \> Grade 2 with the exception of alopecia and neuropathy. 4. Subjects with treated brain metastases with evidence of progression within 28 days after central nervous system (CNS)-directed treatment, as ascertained by clinical examination and brain imaging (magnetic resonance imaging \[MRI\] or computed tomography \[CT\] scan) during the Screening period. 5. Female subjects who can become pregnant (or are already pregnant or lactating), unless they have a negative serum pregnancy test before enrollment and agree to use at least one highly effective form of contraception . 6. Male subjects with partners of childbearing potential, unless they agree to take measures not to father children by using a barrier method of contraception (condom plus spermicide). 7. Major surgery from which the subject has not yet recovered. Part B: Inclusion Criteria: 1. Provide written informed consent. 2. 18 years old or older. 3. Advanced, metastatic, and/or progressive solid tumors with pathogenic molecular alterations: 1. Non-small cell lung cancer (adenocarcinoma); YES1, TYMS amplification or FAT1 pathogenic mutation 2. Non-small cell lung cancer (squamous cell carcinoma); YES1, TYMS amplification or FAT1 pathogenic mutation 3. Renal cancer; NF2 pathogenic mutation 4. Mesothelioma; NF2 pathogenic mutation 5. Other solid tumors with a NF2, FAT1 or LATS1 pathogenic gene mutation or TYMS, YAP1, YES1, or TAZ1 gene amplification, or cholangiocarcinoma with IDH1 or IDH2 mutations. 4. Must have received 1-3 prior therapies appropriate for their tumor type and stage of disease 5. Measurable disease according to Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 (or mRECIST 1.1 for subjects with pleural mesothelioma). 6. Eastern Cooperative Oncology Group (ECOG) performance status of 0-1.
