About
ASP1002 is a potential new treatment for people with certain solid tumors. Before ASP1002 is available as a treatment, the researchers need to understand how it is processed by and acts upon the body. This information will help find a suitable dose and check for potential medical problems from the treatment.
People in this study will be adults with locally advanced or metastatic solid tumors with high levels of a protein called claudin 4. Metastatic means the cancer has spread to other parts of the body. They will have been previously treated with available standard therapies or refused to receive those treatments.
There are 2 main aims of this study. One is to learn if people with certain solid tumors have any medical problems or side effects after receiving different doses of ASP1002. The other is to find a suitable dose of ASP1002 to use in future studies.
This study will be in 2 parts.
In Part 1, different small groups of people will receive lower to higher doses of ASP1002. Any medical problems and side effects will be recorded at each dose. This is done to find suitable doses of ASP1002 to use in Part 2 of the study. The first group will receive the lowest dose of ASP1002. A medical expert panel will check the results from this group and decide if the next group can receive a higher dose of ASP1002. The panel will do this for each dose group until all groups have taken ASP1002 or until suitable doses have been selected for Part 2.
In Part 2, other different small groups of people will receive ASP1002 with the most suitable doses determined from Part 1. This will help find a more accurate dose of ASP1002 to use in future studies.
During both parts of the study, ASP1002 will be given through a vein. This is called an infusion. Each treatment cycle is 21 days long and the infusion is given weekly. People in this study will continue treatment for up to 2 years (32 cycles) until: they have medical problems or side effects that prevent them from continuing treatment; their cancer gets worse; they start other cancer treatment; they ask to stop treatment; they do not come back for treatment.
People will visit the clinic several times during each treatment cycle. They will receive ASP1002 infusions 3 times during each treatment cycle. Each infusion could take 15 minutes to 2 hours, depending on the dose. In addition to infusions, other checks will occur during the visit. During these visits, the study doctors will check for any medical problems and side effects from ASP1002. At some visits, other checks will include a medical examination, laboratory tests and vital signs. Vital signs include temperature, pulse, breathing rate, oxygen saturation, and blood pressure. Also, blood and urine samples will be taken. Tumor samples will be taken during certain visits during treatment and when treatment has finished.
People will visit the clinic within 7 days after stopping treatment. The study doctors will check for any medical problems and side effects from ASP1002. Other checks will include a medical examination, laboratory tests and vital signs. Then, they may visit the clinic at 30 days (1 month) and 90 days (3 months) after stopping treatment. At the 30-day visit, the study doctors will check for any medical problems and side effects from ASP1002. People will have their vital signs checked and have some laboratory tests. At the 90-day visit, the study doctors will check for any medical problems and side effects from ASP1002 and people will have their vital signs checked. After this, people will continue to visit the clinic every 9 to 12 weeks. This is to check the condition of their cancer.

Inclusion criteria
Participant has locally-advanced (unresectable) or metastatic solid tumor which is confirmed by available pathology records or current biopsy.
Participant has progressed, is intolerant, has refused, or there are no standard approved therapies that impart significant clinical benefit (no limit to the number of prior treatment regimens).
Participant has accessible archival tumor tissue (< 6 months old) from either the primary tumor or a metastatic site, for which source and availability have been confirmed prior to study intervention; participants without available tissue should undergo a mandatory biopsy. If the participant is unable to undergo a biopsy due to safety concerns, enrollment into the study is at the discretion of the medical monitor. Participant should undergo a tumor biopsy during the treatment period as indicated in the schedule of assessments. Note: Tumor tissue collection (at screening/baseline and on-treatment) is optional for participants enrolled initially in dose levels 1 to 3 in dose escalation; however, protocol de-escalation and expansion of dose levels similar to dose levels 1 to 3 may require collection and processing of screening/baseline and on-treatment tumor samples.
Participant has at least 1 measurable lesion per RECIST v1.1. Lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions.
Participant has an Eastern Cooperative Oncology Group (ECOG) Status of 0 or 1.
Participants who have received radiotherapy must have completed this therapy (including stereotactic radiosurgery) at least 2 weeks prior to study intervention administration.
Participant has predicted life expectancy >/= 12 weeks.
Participant has adequate organ function prior to start of study intervention. If a participant has received a recent blood transfusion, the laboratory tests must be obtained >/=2 weeks after any blood transfusion.
Female participant is not pregnant and at least 1 of the following conditions apply:
Female participant must agree not to breastfeed starting at screening and throughout the study period and for 90 days after final study intervention administration.
Female participant must not donate ova starting at first administration of study intervention and throughout 90 days after final study intervention administration.
Male participant with female partner(s) of childbearing potential (including breastfeeding partner) must agree to use contraception throughout the treatment period and for 90 days after final study intervention administration.
Male participant must not donate sperm during the treatment period and for 90 days after final study intervention administration.
Male participant with pregnant partner(s) must agree to remain abstinent or use a condom for the duration of the pregnancy throughout the study period and for 90 days after final study intervention administration.
Participant agrees not to participate in another interventional study while receiving study intervention in the present study.
Exclusion criteria
