What the trial was testing
The trial enrolled 48 patients with melanoma. The study was sponsored by Inge Marie Svane and tracked outcomes across the full group of patients who matched the trial's eligibility profile.
It was an early-stage trial — researchers are still confirming safety and getting an early look at how well the treatment works. Trials at this stage are designed to produce evidence regulators and physicians can act on — not just observations to follow up later.
What the results showed
80% tumor response rate, including 43% complete responses.
Nature Medicine · 2021 · NCT03047928
These findings — that in untreated metastatic melanoma on the IDO/PD-L1 vaccine plus nivolumab — were published in the Nature Medicine and represent the headline result of the study.
Researchers tracked outcomes across 48 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.
What this means for patients
For patients with melanoma, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.
What you can do now
The IO102/IO103 vaccine is still in development and not yet FDA-approved. Nivolumab (Opdivo) alone or with ipilimumab (Yervoy) is FDA-approved and available now for metastatic melanoma. Other newer combinations like nivolumab + relatlimab (Opdualag) are also approved. Ask an oncologist about approved options or trials.
Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.

Neoadjuvant and Adjuvant Anti-PD1 or Combinations for Locoregionally Advanced Melanoma
The purpose of this study is to determine if neoadjuvant (treatment before surgery) immunotherapy treatment based on tumor biomarkers results in better participant outcomes. Immunotherapy is the treatment of disease by using a person's own immune system. This study is divided into 2 sub-studies/parts designated Part 1 and Part 2 that will enroll in sequence starting with Part 1 followed by Part 2.
A Study to Evaluate ARV-6723 Alone and With Pembrolizumab in Participants With Advanced Solid Tumors
This is a study to evaluate the safety and potential anti-tumor activity of an investigational drug called ARV-6723, in participants with advanced solid tumors. This is an open-label study which means that participants and study staff will know that all participants will receive ARV-6723. The investigational drug ARV-6723 will be given as an oral tablet on its own and also in combination with other drugs. Researchers think that ARV-6723 can help the body's immune system to better recognize, attack, and destroy cancer cells in adults with advanced solid tumors. ARV-6723 is an investigational drug, and this is the first time ARV-6723 will be used in humans. Depending on the treatment assignment, the investigational drug, ARV-6723, will be given as an oral tablet either on its own (monotherapy) or in combination with pembrolizumab, either through a vein (intravenously or IV) or through an injection beneath the skin (subcutaneously or SQ). This study will include multiple parts: In Part A1 (Phase 1a), different small groups of participants will receive lower to higher doses of ARV-6723 as monotherapy or in combination with standard-dose of pembrolizumab. In Part A2 (Phase 1b), two groups of participants with specific tumor indication(s) (TBD) will receive one of two doses selected based on information from Part A1. Details of Part B will be determined based on information generated from Part A.
