Description of intervention(s) / exposure
Treatment: Drugs - [177Lu]Lu-SN201

Experimental: Phase I/IIa Dose escalation and dose expansion - Participants will initially receive 1 cycle of \[177Lu\]Lu-SN201 via slow intravenous infusion and progress to up to 3 cycles, provided retreatment criteria are met before the start of each cycle, occurring every 6 weeks (with an allowable window to delay each cycle by +3 weeks per retreatment criteria).

Dose escalation: The study will evaluate up to 5 dose levels of \[177Lu\]Lu-SN201 (A1=10 MBq/kg, A2=25 MBq/kg, A=50 MBq/kg, A4= \<33% of A3, A5= \<33% of A4). Additional dose levels may be explored until MTD/RP2D is identified. Up to 9 participants may be enrolled at any pre-specified dose level shown to be tolerated for confirmation of MTD and/or RP2D.

Dose expansion: Once the MTD/RP2D has been defined, an expansion phase consisting of multiple tumor types, each with up to 20 participants, will be enrolled to further characterize the safety, tolerability, and assess preliminary efficacy of \[177Lu\]Lu-SN201 at the RP2D and/or MTD identified in Phase I.

Eligibility
Key inclusion criteria
Inclusion criteria:

1. Male or female participants = 18 years of age on the day of signing informed consent.
2. Histologically or cytologically documented, recurrent, locally advanced, or metastatic solid malignancy that has failed at least one prior systemic standard therapy, or for which standard therapy is not appropriate, or for which no standard therapy exists.
3. Eastern Cooperative Oncology Group (ECOG) performance status 0-2.
4. Life expectancy = 3 months.

1. Hemoglobin = 9.0 g/dL (transfusions are allowed).
2. Absolute neutrophil count (ANC) = 1500/mm3.
3. Platelet count = 100,000 mm3.
4. Total bilirubin = 2.5 x upper limit of normal (ULN) (in participants with liver metastases = 5 ULN).
5. Alanine transaminase (ALT) and aspartate transaminase (AST) = 5 x ULN.
6. On a stable dose of anti-coagulation therapy will be allowed to participate if they have no sign of bleeding or clotting and prothrombin/international normalized ratio and partial thromboplastin time (PT/INR and PTT, respectively) test results are compatible with the acceptable benefit-risk ratio at the Investigator's discretion.
7. Serum creatinine = 1.5 x ULN and estimated glomerular filtration rate (eGFR) > 30 mL/min/1.73 m2 (per local values).
8. Contraceptive use by men and women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies.

1. Male participants must agree to use a highly effective method of birth control as defined in ICH M3(R2) starting with the first dose of study medication through 120 days after the last dose of study medication.
2. Female participants of childbearing potential* must have a negative pregnancy test documented at Screening and Baseline and be willing to use a highly effective method of contraception** or practice abstinence starting from ICF signature through to 120 days after the last dose of study medication.

* A female of childbearing potential is a sexually mature female who 1) has not undergone a hysterectomy or bilateral oophorectomy, or 2) has not been naturally postmenopausal for at least 24 consecutive months (i.e., had had menses at any time in the preceding 24 consecutive months).

* Effective contraception is defined as contraceptive methods with a failure rate of < 1% to prevent pregnancy (combined [estrogen and progestogen containing] hormonal contraception associated with inhibition of ovulation [oral, intravaginal, transdermal], progestogen-only hormonal contraception associated with inhibition of ovulation [oral, injectable, implantable], intrauterine device [IUD] or intrauterine hormone-releasing system).

Summary
Brief summary
The purpose of this first-in-human (FIH) study is to determine the maximum tolerated dose (MTD) and to characterize the safety, tolerability, PK, and dosimetry profile of \[177Lu\]Lu-SN201 in adult participants with advanced solid tumors who have no standard of care treatment options.

\[177Lu\]Lu-SN201 is a radiolabeled, nanomedical investigational medicinal product (IMP) whose mechanism of delivery is based on the Enhanced Permeability and Retention (EPR) effect.
