Ochsner Health advances precision medicine, becomes national leader in universal genomic testing for chemotherapy

New Orleans-based Ochsner Health is one of the first in the nation to regularly use genomic testing for cancer drugs and other medications to better patient outcomes

( New Orleans, Louisiana – Ochsner Health is leading the way for precision medicine nationwide by becoming one of the first hospital systems to standardize genomic testing, significantly advancing ways in which care teams can treat cancer patients. This change helps providers determine individualized treatment by understanding how patients will react to certain drugs, thereby lowering risk of adverse side effects, improving patient experience, and bettering patient outcomes.

Pharmacogenomics, or PGx, testing guides physicians how patients metabolize certain drugs and warns of possible side effects so they may adjust dosage in a way that provides individualized, personalized treatment. After a Louisiana law requiring insurance companies pay for the testing went into effect last year, Ochsner made it a required test for cancer patients receiving two types of chemotherapy drugs – 5-fluorouracil and capecitabine. The testing is now available at Ochsner's Baton Rouge and New Orleans regions and in Northern Louisiana locations. It will become a systemwide practice in coming months.

“We are leading the nation in this area,” said Marc Matrana, M.D., M.S., F.A.C.P., Ochsner Health’s System Medical Director for Precision Medicine and Endowed Professor of Experimental Therapeutics. “This is something unique Ochsner is at the forefront of, that is preventing hospitalization and saving lives. We’ve built this in a very thoughtful way, from advocating for new laws around reimbursement to integrating safety stops into the electronic medical record, that will serve as an example to the rest of the world.”

These tests are part of a pharmacogenomics program Ochsner launched in March 2022, available to all the health system’s patients. The service includes a comprehensive panel obtained through a standard blood test. It evaluates the function of nearly 30 genes and can provide useful information for about 200 medications. In addition to helping determine dosage of cancer treatment drugs, the test can help those who are prescribed blood thinners, have a history of adverse side effects to medications, require pain medications and who take medicine for a mental health condition, among others. It’s now used at Ochsner in a variety of specialties, including cardiology, psychiatry, cancer, rheumatology, pain management and infectious disease. Physicians and pharmacists can use the information to understand which medications and dosage regimens a patient is most likely to best respond. When applied in clinical practice, these pharmacogenomic results help patients because they can find which personalized therapeutics work for them more quickly and reduce potential treatment failures.

“These tests are innovative, but we are using peer-reviewed and evidence-based guidelines available for the drug/gene interactions for which we are testing,” said Catherine Oliver, PharmD, BCPS, DPLA, CPGx, System Director of Clinical Pharmacy Services for Ochsner Health. “Even if the patient doesn’t use the medications at the time of the test, it helps providers make decisions about individual care going forward.”

According to the Institute for Safe Medication Practices, barriers to widespread pharmacogenomic testing in clinical practice include the cost of testing, potential delays in patient care, potential lack of consensus dosing recommendations, and general lack of knowledge of recommendations by clinicians.

Through the work of local advocacy groups and cancer providers in Louisiana, insurance coverage for genomic testing is now required for patients with cancer diagnoses. Many of those patients have zero out-of-pocket costs associate with this testing, and for those who do incur out of pocket expenses, the costs are on average less than $100.  Ochsner is one of the first hospital systems to have fully integrated this process into its electronic health records, placing pharmacogenomic information at providers’ fingertips so they can personalize care when needed.  

Ochsner is also leading the way in PGx by covering the cost of testing under its three employee health plans for employees with certain mental health diagnoses. The one-time lab panel looks at a patient’s DNA to predict response to certain medications, including behavioral health therapies.

Ochsner’s testing partner, OneOme, is also working with other insurance plans to make testing as affordable as possible. All Medicare or Medicaid patients will have no out-of-pocket cost. While each patients’ commercial insurance plans vary, OneOme has a generous financial assistance program available to those who qualify.

Through the relationship with OneOme, Ochsner providers can have results in about five days, which prevents delays in care for cancer patients and others.  Discrete results automatically flow back into the health record, making them useful for care teams.  Pharmacogenomic testing is only needed once during a lifetime for most patients, and it is reflected in the patient’s record in a way that it is readily accessible now or in the future.

Bigger flowers, greater rewards: Plants adapt to climate disruptions to lure pollinators

  Photos There's been a well-documented shift toward earlier springtime flowering in many plants as the world warms. The trend alarms biologists because it has the potential to disrupt carefully choreographed interactions between plants and the creatures—butterflies, bees, birds, bats and others—that pollinate them.   But much less attention has been paid to changes in other floral traits, such as flower size, that can also affect plant-pollinator interactions, at a time when many insect pollinators are in global decline.   In ...

Novel disease models for multiple myeloma

Novel disease models for multiple myeloma
B lymphocytes – also known simply as B cells – play a central role in the immune system. If pathogens enter the body, B cells are activated and develop into plasma cells, which then release antibodies. One important step in this process is the germinal center reaction. If the B cells’ maturation into plasma cells is disrupted, multiple myeloma can develop – one of the most common blood cancers. This disease has a variety of subtypes and is not yet curable. Multiple myelomas develop very slowly and in several stages. The process is initiated by spontaneous genetic aberrations that occur ...

Clinical trial investigating innovative way to control Type 2 diabetes

Clinical trial investigating innovative way to control Type 2 diabetes
LOS ANGELES — More than 37 million Americans have diabetes, and approximately 90-95% have Type 2 diabetes. Diabetes is a chronic condition where the body does not produce or effectively use insulin. A lack of insulin leads to raised blood glucose (sugar) levels, which can cause heart disease and stroke, kidney disease, nerve damage and other severe complications. Keck Medicine of USC has launched a Phase 2 clinical trial investigating the effectiveness of a new outpatient, nonsurgical endoscopic procedure in stabilizing blood glucose levels for patients.  “Currently, the only treatment for diabetes ...

Humans bite back by deactivating mosquito sperm

Humans bite back by deactivating mosquito sperm
New UC Riverside research makes it likely that proteins responsible for activating mosquito sperm can be shut down, preventing them from swimming to or fertilizing eggs. The study could help control populations of Culex, the common house mosquito that transmits brain-swelling encephalitis and West Nile Virus.  “During mating, mosquitoes couple tail to tail, and the males transfer sperm into the female reproductive tract. It can be stored there awhile, but it still has to get from point A to point B to complete fertilization,” said Cathy Thaler, UCR cell biologist and the study’s first author.  Key to completing that journey are the specialized proteins secreted ...

The results, from the first study of its kind, provide insights that can be used to design and implement future, targeted interventions to optimize hand hygiene reliability among medical professionals. “While prior studies focused on challenges to hand hygiene reliability by healthcare role, we believe our study is the first to highlight key differences in perceived barriers ...

Common meat-free proteins may trigger soybean and peanut allergies in some people

Many people keen to reduce their meat consumption are turning to substitutes made of legumes packed with protein, vitamins, and fiber. But allergies to legumes like soy or peanuts are both common and dangerous. Are patients allergic to particular legumes at risk from meat-free proteins made of legumes even if they contain different legumes? Dr Mark Smits and a team of scientists at University Medical Center Utrecht set out to investigate. “Both protein consumption and the world’s population are increasing which leads to an urgent demand for sustainable ...

A comprehensive circuit mapping study reveals many unexpected facts about the norepinephrine neurons in the brainstem

A small nucleus in the brainstem called locus coeruleus (literally the “blue spot,”) is the primary source of a major neuromodulator, norepinephrine (NE), an important mediator of the ‘fight or flight’ response in animals. However, very little is known about the local connections of this small albeit critically important group of neurons. A recent pioneering study published in eLife from the laboratory of Dr. Xiaolong Jiang, investigator at the Jan and Dan Duncan Neurological Research Institute (Duncan NRI) ...

Maintaining heart function in donors declared ‘dead by circulatory criteria’ could improve access to heart transplantation

More donated hearts could be suitable for transplantation if they are kept functioning within the body for a short time following the death of the donor, new research has concluded. The organs are kept functioning by restarting local circulation to the heart, lungs and abdominal organs – but, crucially, not to the brain – of patients whose hearts have stopped beating for five minutes or longer and have been declared dead by circulatory criteria (donation after circulatory death, or DCD). It is hoped that this technique could increase the number of usable donated hearts by as much as 30% in the future, helping address ...
