Inclusion criteria
Inclusion criteria: 1.Signed the informed consent form (ICF) to participate in this study by him/herself. 2.Male and female aged 18 years or above at the time of informed consent. 3.Have histologically confirmed solid tumor. 4.Refractory to standard treatment for advanced or recurrent solid tumors, or the Investigator/Sub-investigator considered that there are no standard or equivalent treatments available for the patient. 5.Have at least 1 lesion that can be illuminated with the laser system, and the tumor falls under one of the cancer types and sites which completed risk assessment of treatment with the investigational device in this study. 6. Completed PD-L1 testing (by IHC assay) and the result in PD-L1 expression (either PD-L1 positive or negative) is available. The results of previous PD-L1 testing (IHC assay) can be used if the sample was collected within 6 months prior to enrollment and provided that no systemic therapy or local therapy to the sample collection site has been administered during that period. 7.Can provide sufficient formalin-fixed, paraffin-embedded (FFPE) tumor tissue samples for PD-L1 IHC testing and other exploratory biomarker testing. 8.Have sufficient function of major organs (hematopoietic organ, liver, kidney, heart, and lung). 9.Eastern Cooperative Oncology Group Performance Status Scale (ECOG PS) is 0 or 1. 10.Expected to survive at least 3 months. 11.Can be hospitalized from D1 of the run-in phase in Part A until completion of observations, tests, and assessments specified on D8 of the run-in phase in Part A and from C1D1 in all Parts until completion of observations, tests, and assessments specified on C1D9 in all Parts. 12.Female patients must not be pregnant (i.e., must be tested negative for urine or serum pregnancy test at screening) or breastfeeding. They must agree to use 2 methods of highly effective birth control, or practice abstinence, as well as not to provide any eggs (ova and oocytes) for reproduction purposes throughout the study period and for at least 180 days after the final RM-0256 dose. Women who are breastfeeding may be enrolled after stopping breastfeeding. However, they must wait at least 120 days to restart breastfeeding after treatment completion. 13.Male patients must be sterile or agree to use a highly effective method of contraception or practice abstinence, as well as not to provide sperm for reproductive purposes throughout the study period and for at least 120 days after the final RM-0256 dose.
Exclusion criteria
Exclusion criteria: Medical history 1. Malignant tumor other than the target disease within the past 2 years. This criterion does not apply to diseases with a low recurrence risk, including adequately treated intraepithelial cancer, intramucosal cancer, low-grade non-melanoma skin cancer, focal prostate cancer, and ductal carcinoma in situ. Other diseases with similar low recurrence risk or diseases which require no treatment may be deemed eligible based on discussions between the Investigator/Sub-investigator and the Medical Monitor. 2. Active metastasis in the central nervous system (CNS) or carcinomatous meningitis. However, patients with CNS metastasis that are considered clinically stable, and confirmed by imaging not to be progressing for more than 4 weeks, may be deemed eligible based on discussions between the Investigator/Sub-investigator and the Medical Monitor. 3. Pleural or ascites or pericardial effusion requiring drainage. 4. Current or past medical history of interstitial lung disease. However, localized pulmonary fibrosis occurring in the irradiated area is permitted. 5. Uncontrolled current medical history of cardiovascular disorders including the following but not limited to acute or chronic congestive heart failure, unstable angina pectoris, atrial fibrillation, other cardiac arrhythmias, myocardial infarction, coronary/peripheral artery bypass graft surgery, cardiomyopathies, cerebrovascular accident, transient ischemic attack, deep vein thrombosis, or symptomatic pulmonary embolism. 6. Current or past medical history of chronic or recurrent autoimmune disease requiring systemic treatment. However, if the disease is controlled with replacement therapy, the patient may be deemed eligible based on discussions between the Investigator/Sub-investigator and the Medical Monitor. 7. Current medical history of active infection requiring systemic treatment such as antibiotic(s) or antifungal/antiviral drug administration. 8. Active or latent hepatitis B (HBs antigen positive; or HBs antigen negative and HBs or HBc antibody positive; and HBV-DNA assay positive) and/or hepatitis C (HCV antibody positive and HCV-RNA assay positive). 9. Current or past medical history of testing positive for human immunodeficiency virus (HIV) infection or acquired immunodeficiency syndrome (AIDS) related diseases. 10. Known history of testing positive for qualitative HTLV-1 (human T-cell lymphotropic virus type 1). 11. Known history of Grade 3 or higher irAEs caused by immune checkpoint inhibitors, leading to treatment discontinuation. 12. Known to have Grade 3 or higher hypersensitivity to the components of RM-0256 (AB-256 [antiPD-L1 antibody], IR700 and excipients included in this drug). 13. The tumor to be illuminated is invading any areas where there is a risk of functional impairment or significant hemorrhage. 14. Current or past medical history of Grade 3 or higher tumor hemorrhage within the past 12 weeks. However, if the patient has received appropriate treatment such as transfusion or hemostatic therapy and currently shows no signs of active bleeding with stable general condition, the patient may be deemed eligible based on discussions between the Investigator/Sub-investigator and the Medical Monitor. 15. Prior allogeneic tissue/solid organ transplant. Prior/Concomitant medications 16. Treated with anti-cancer treatment for a specific period, as described below. However, this criterion does not apply to zoledronic acid hydrate or denosumab initiated befor
