What the trial was testing
The trial enrolled 65 patients with melanoma. The study was sponsored by Yale University and tracked outcomes across the full group of patients who matched the trial's eligibility profile.
It was initial testing (phase 2). 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
22% of melanoma patients and 33% of lung cancer patients saw brain tumors shrink.
The Lancet. Oncology · 2016 · NCT02085070
These findings — that saw their brain tumors shrink with pembrolizumab treatment — were published in the The Lancet. Oncology and represent the headline result of the study.
Researchers tracked outcomes across 65 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
This was an initial testing study. Pembrolizumab is now FDA-approved for melanoma and certain lung cancers, including some cases with brain metastases. If you have cancer that has spread to your brain, ask your oncologist whether pembrolizumab or similar immunotherapy might be an option for you.
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.

Effectiveness of Fractionated Laser Resurfacing to Protect Geriatric Skin From Actinic Neoplasia
This study is following up on previous studies that have demonstrated that geriatric subjects respond different to ultraviolet B (UVB) light than young subjects. The treatment of geriatric skin with dermal rejuvenation therapies (dermabrasion, fractionated laser resurfacing) restores the appropriate UVB response. Ongoing studies have tested the ability of fractionated laser resurfacing (FLR) to assess how long this wounding effect lasts-and have found that this appears to be a durable response which lasts for at least two years. The findings that FLR protects geriatric skin at two years is the impetus for this study. This study is an interventional study to assess if FLR treatment of one forearm of geriatric subjects with multiple actinic keratosis will result in the short-term removal of actinic keratosis, and the long-term decrease in levels of future actinic keratosis and other non-melanoma skin cancers in comparison to the untreated arm. Study length and visit: The first part of the study is completed in 1 day then there are follow up visits at 90 days and every 6 months for 5 years.
ORACLE: Observation of ResiduAl Cancer With Liquid Biopsy Evaluation
The purpose of ORACLE is to demonstrate the ability of a novel ctDNA assay developed by Guardant Health to detect recurrence in individuals treated for early-stage solid tumors. It is necessary that ctDNA test results are linked to clinical outcomes in order to demonstrate clinical validity for recurrence detection and explore its value in a healthcare environment subject to cost containment.
