Brief Summary

This study was for women with breast cancer and for adults with melanoma. Breast cancer was a type of cancer when cells in the breast turn into cancer cells, which might grow out of control. Melanoma was a type of skin cancer that starts in cells called melanocytes. These cells made a substance called melanin which gives the skin its color. In this study, people had surgery to remove the lymph node closest to the site of their cancer. This lymph node was called the sentinel node. This was done to check if the cancer had spread from the original site to the sentinel node. This procedure was called a sentinel node biopsy. This study provided more information on a potential new dye, called ASP5354, used in sentinel node biopsies. ASP5354 helped to show the lymph nodes more clearly during surgery. This helped the surgeon find the lymph node closest to the site of the cancer (sentinel node). The main aim of the study was to find the best dose of ASP5354 that clearly showed the lymph nodes during surgery. This was an open-label study. That means each person in the study and the study doctors knew that person received ASP5354. Each person only received 1 dose of ASP5354. People that wanted to take part in the study were checked by a study doctor. This was on a separate visit before their surgery. Before surgery, people who took part in the study were asked if they had any other medical problems. They had a physical exam, an ECG to check their heart rhythm, and had their vital signs checked (blood pressure, pulse rate, and breathing rate). Other checks included some blood and urine samples taken for laboratory tests. During surgery, a study surgeon injected ASP5354 near the cancer site. They recorded how clearly they could see the lymph nodes. Some blood samples were taken for laboratory tests and an ECG was done. After their surgery, people were asked if they have any other medical problems. People returned to the hospital 9 days later for a check-up. The check-up included a physical exam, an ECG to check their heart rhythm, and a check of their vital signs (blood pressure, pulse rate, and breathing rate). Other checks included some blood samples taken for laboratory tests. People were asked if they had any medical problems and asked to complete a feedback survey.

Outcome Measures

Primary Outcomes (1)

• Optimal Dose of ASP5354 for Lymph Node (LN) Visualization

  The optimal dose was defined as the dose that provided a better visualization compared with lower doses and a comparable visualization to the next higher dose. In the case where 2 doses performed equally, the lower dose was selected. Cumulative visualization data of the LNs from all treated participants was used for optimal dose determination. The optimal dose was determined by the Visualization Review Committee (VRC) using data from the following assessments: LN tissue visualized (Y/N), visualized tissue is lymphatic in origin based on pathologic confirmation, Likert Scale determination of the intensity of fluorescence, and proportion of identified LN with histopathologic confirmation of LN tissue by ASP5354 compared with standard of care (SOC) treatment.

  Day 1

Secondary Outcomes (4)

• Percentage of Participants With at Least 1 LN Detected Using ASP5354

  Day 1 up to day 10

• Percentage of Identified LN Tissue by ASP5354 Compared With SOC Treatment

  Day 1 up to day 10

• Number of Participants With Treatment Emergent Adverse Events (TEAE) and Serious Adverse Events (SAE)

  From first dose up to day 10

• Plasma Concentration of ASP5354

  Predose, approximately 10 minutes, 30 minutes, 60 minutes postdose, and at the end of surgery (day 1)

Eligibility Criteria

• Age: 18 Years+
• Gender Eligibility Details: Females only for breast cancer segment
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Participant has been diagnosed with localized breast cancer (female only, stage 1 to 2, N0 and M0) or melanoma (stage 1 to 2, N0 and M0) and is scheduled to undergo surgical intervention for systemic lymph node (SLN) detection and removal using Technetium-99m sulfur colloid or Lymphoseek as part of Standard of Care (SOC).
• Female participant is not pregnant and at least 1 of the following conditions apply:
• Not a woman of childbearing potential (WOCBP)
• WOCBP who agrees to follow the contraceptive guidance from the time of informed consent through at least 30 days after final study treatment administration.
• Female participant must agree not to breastfeed starting at screening and throughout the study period and for 30 days after final study treatment administration.
• Female participant must not donate ova starting at first dose of Investigational Product (IP) and throughout the study period and for 30 days after final study treatment administration.
• Male participant with female partner(s) of childbearing potential (including breastfeeding partner) must agree to use of contraception throughout the treatment period and for 30 days after final study treatment administration.
• Male participant must not donate sperm during the treatment period and for 30 days after final study treatment 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 30 days after final study treatment administration.
• Participant agrees not to participate in another interventional study while participating in the present study.

You may not qualify if:

• Participant has had prior lymph node (LN) surgery in the area where LN detection is needed.
• Participant has had prior LN radiation in the area where LN detection is needed.
• Participant has had prior neo-adjuvant chemotherapy.
• Participant has definitive LN metastases.
• Participant has metastatic cancer.
• Participant has received any investigational therapy within 28 days or 5 half-lives, whichever is longer, prior to screening.
• Participant has any condition which makes the participant unsuitable for study participation.
• Participant has a known or suspected hypersensitivity to ASP5354, indocyanine green (ICG) or any components of the formulation used.
• Participant has had previous exposure to ASP5354.
• Participant has moderate to severe cardiac disease that limits daily functioning (New York Heart Association Class III-IV) or other medical conditions that would impact safety or study compliance.
• Participant has a resting heart rate \<= 45 beats per minute (bpm) or \>=115 bpm, systolic blood pressure \>=160 mm Hg or diastolic blood pressure \>= 100 mm Hg within 1 week prior to IP administration. If the blood pressure exceeds the limits above, repeat readings can be taken. Participant who has adequately controlled blood pressure is eligible.
• Participant has any of the screening laboratory values outside of the protocol specification criteria.
• Participant has received ICG, other near-infrared fluorescence (NIR-F) imaging agents, Blue dye (e.g., methylene blue or isosulfan blue) or magtrace within 2 weeks prior to IP administration.
• Participant has active alcohol abuse or illicit drug use (non-prescription or over-the-counter medications). Participant should not have consumed any alcohol or illicit drug (excluding cannabidiol products) within 24 hours of surgery.
