Industry Relationships

Cleveland Clinic physicians and scientists may collaborate with the pharmaceutical or medical device industries to help develop medical breakthroughs or provide medical expertise or education. Cleveland Clinic strives to make scientific advances that will benefit patient care and support outside relationships that promise public benefit. In order for the discoveries of Cleveland Clinic physicians' and scientists' laboratories and investigations to benefit the public, these discoveries must be commercialized in partnership with industry. As experts in their fields, Cleveland Clinic physicians and scientists are often sought after by industry to consult, provide expertise and education.

To assure professional and commercial integrity in such matters, Cleveland Clinic maintains a program that reviews these collaborations and, when appropriate, puts measures in place to minimize bias that may result from ties to industry. Cleveland Clinic publicly discloses the names of companies when (i) its physicians/scientists receive $5,000 or more per year (or, in rare cases, equity or stock options) for speaking and consulting, (ii) its physicians/scientists serve as a fiduciary, (iii) its physicians/scientists receive or have the right to receive royalties or (iv) its physicians/ scientists hold any equity interest for the physician's/scientist's role as inventor, discoverer, developer, founder or consultant.* In publicly disclosing this information, Cleveland Clinic tries to provide information as accurately as possible about its physicians' and scientists' connections with industry.

As of 3/9/2021, Dr. Lang has reported no financial relationship with industry that is applicable to this listing. In general, patients should feel free to contact their doctor about any of the relationships and how the relationships are overseen by Cleveland Clinic.

Public Health Service-Reportable Financial Conflicts of Interest. Cleveland Clinic scientists and physicians engage in basic, translational and clinical research activities, working to solve health problems, enhance patient care and improve quality of life for patients.

Dr. Lang always spends a lot of time with me and is one of the best doctors I have ever had.

Reviewed on May 3, 2021

Dr. Lang was excellent. I learned so much about my condition at this appointment and I will always refer people to him who have anaphylaxis concerns. He is extremely knowledgeable. The only thing that caught me off guard was finding out I was on a medication prescribed by a previous physician that wasn't beneficial. It would have been helpful for him to describe why that wasn't a good medication to take. Sometimes I felt I was being quizzed more than being asked questions. This just might be a difference in personality styles though. I work in healthcare administration so I'm always trying to be respectful and understanding of different bedside manners. I sincerely appreciated his time and effort into my condition. He went the extra mile by printing updated research and data so I really appreciated that. I look forward to working with him in the future!
