On August 19, 2024, the U.S. Food and Drug Administration (FDA) approved lazertinib (Lazcluze^™) in combination with amivantamab-vmjw (Rybrevant^®) for first-line treatment of locally advanced or metastatic non-small cell lung cancer with epidermal growth factor receptor exon 19 deletions or exon 21 L858R substitution variants, as detected by an FDA-approved test.

On June 13, 2024, the U.S. Food and Drug Administration granted accelerated approval to repotrectinib (Augtyro^™) for adult and pediatric patients aged 12 and older with solid tumors that have a neurotrophic tyrosine receptor kinase (NTRK) gene fusion, are locally advanced or metastatic or where surgical resection is likely to result in severe morbidity, and that have progressed following treatment or have no satisfactory alternative therapy.

On June 12, 2024, the U.S. Food and Drug Administration (FDA) granted traditional approval to selpercatinib (Retevmo^®) for adult and pediatric patients aged 2 years and older with advanced or metastatic RET fusion–positive thyroid cancer that requires systemic therapy but is refractory to radioactive iodine (RAI), if RAI is appropriate.

Eflornithine (Iwilfin™) is the first U.S. Food and Drug Administration–approved oral maintenance therapy for high-risk neuroblastoma. Approved in December 2023, eflornithine has an orphan drug designation.

Since the first bispecific antibody (BsAb), blinatumomab, received U.S. Food and Drug Administration approval in 2014, the drug class has developed exponentially, with the majority of currently approved agents entering clinical practice in the past two years. BsAbs are very effective for treating certain malignancies, including multiple myeloma and leukemia, and most are approved for oncology indications. Here’s what makes BsAbs different than other cancer treatments and the key considerations for oncology nursing clinical practice.

On March 7, 2024, the U.S. Food and Drug Administration (FDA) granted accelerated approval to zanubrutinib (Brukinsa^®) with obinutuzumab for relapsed or refractory follicular lymphoma after two or more lines of systemic therapy.

On November 21, 2023, the U.S. Food and Drug Administration (FDA) advised that Bayer issued a voluntary recall for one lot of larotrectinib (Vitrakvi^®) oral solution 20 mg/ml in 100 ml glass bottles to the user level because of Penicillium brevicompactum microbial contamination observed during routine stability testing.

Personalizing cancer treatments through targeted drugs and customized doses can make strides in care for pediatric patients with cancer, cancer specialists said in the National Institutes of Health's News in Health.

Since the first checkpoint inhibitor was approved in 2011, we have made tremendous leaps in immunotherapy in a short span of 10 years. Now we see immunotherapy combined with a variety of options, including chemotherapy or other oral and IV targeted therapy.

Understanding the underlying mechanisms of cancer­related symptoms enables oncology nurses to provide the best patient-centered care. Biosignatures are indicators of life, and in disease, they contribute to the determination of clinical profiles. Identifying specific biologic markers associated with similar patient characteristics and symptoms may help us create tailored interventions for improved symptom management.

Genetic counselors have a unique ability to explain complex genetic information to patients, providers, and our healthcare colleagues and to empower patients to take an active role in their healthcare decisions. We review biosignature data points and help explain the difference between variants that were acquired (somatic) versus those that may have a germline component, or possibly inherited from a parent. By working with oncology teams, genetic counselors provide guidance on potential next steps to evaluate variation occurrences and how providers, patients, and their families can use the information to guide their care.

With the growth of genomics and targeted therapy, nurse scientists are gaining deeper understanding the vast facets of patients’ symptom experience, and biosignatures could be the key to unlocking the next frontier in symptom science research.

Researchers have found that 2%–3% of all solid tumors overexpress or amplify HER2 protein that may be a target for drugs such as pertuzumab and trastuzumab, particularly in KRAS-variant disease. They presented their findings during the 2021 American Society of Clinical Oncology annual meeting.

Randi is a 57-year-old patient who identifies as female. She was diagnosed with clear cell metastatic renal cell carcinoma (mRCC), and her past medical history includes mild hypertension managed with amlodipine and a two-year history of transient musculoskeletal pain managed with tramadol. She reports a family history of cardiovascular disease and rheumatoid arthritis (RA). Her primary care physician suspects Randi is at the beginning stages of fibromyalgia but has not made a conclusive diagnosis because she hasn’t experienced additional symptoms.

Testing for molecular biomarkers has become a mainstay in determining treatment approaches for advanced-stage non-small cell lung cancer. Typically, next-generation sequencing identifies any potential genomic variants that are associated with oncogenic driver events and can be targeted with oral tyrosine kinase inhibitors.

Pirtobrutinib, an investigational, third-generation Bruton tyrosine kinase (BTK) inhibitor, offered response rates of 60% or higher in most groups of heavily pretreated patients with chronic lymphocytic leukemia (CLL), even those who’ve received other BTK inhibitors as previous treatment, researchers reported in Lancet.

In 2018, the cancer drug larotrectinib quietly became a milestone along the evolving path to approaching cancer therapy: it was the first agent approved to treat a genetic variant, not a specific type of cancer or disease site. And as oncology treatment science progresses, many predict that it won’t be the last—it’s already been joined by pembrolizumab and entrectinib as tumor-agnostic therapies. The key to curing cancer may be hidden in the disease’s genetic code rather than its location in the body.

When genetically modified with a chimeric antigen receptor (CAR), natural killer T (NKT) cells eliminated 50% of metastases in a patient with heavily pretreated, relapsed or refractory metastatic neuroblastoma, according to interim findings from an ongoing study that were published in Nature Medicine.

Researchers have developed a device that can separate various cell types in patient blood samples based on the cell size, which may one day enable rapid, inexpensive liquid biopsies to help clinicians detect cancer and develop targeted treatment plans. Findings from the research that led to the device are reported in Microsystems and Nanoengineering.

New treatment options continue to emerge for diseases that until recently had limited, if any, treatment choices. Nurses are seeing more changes in the way treatment regimens come together, biosimilars are presenting viable options for patients, and genetic mutations, as opposed to disease sites, are at the forefront of drug development.  

Targeted therapies block the growth of cancer by interfering with specific molecules and may also be referred to as molecularly targeted drugs or precision oncology. Advanced practice RNs (APRNs) must be familiar with the various agents and their side effect profiles, including immunotherapies, hormone therapies, apoptosis inducers, monoclonal antibodies, angiogenesis inhibitors, and signal transduction inhibitors. 

Every cancer diagnosis is as individualized and unique as the person receiving it. From family history to societal and economic background to a patient’s genetic make-up and composition, cancer affects each person with cancer differently. Initiatives like precision medicine are based in data that suggest that a personalized disease should have its own personalized treatment. As a subset of precision medicine, precision oncology assesses a patient’s unique genetic profile to help align targeted therapies to hit the right cancer subtypes. 

Ribociclib is a CDK 4/6 inhibitor first approved by the U.S. Food and Drug Administration in early 2017 for postmenopausal women with HR-positive, HER2-negative advanced or metastatic breast cancer in combination with an aromatase inhibitor as initial endocrine therapy, based on the MONALEESA trial results. 

This is the third in a series detailing some of the general factors to consider around patient adherence to oral medications, and ways to support patients receiving neratinib.

AS is a 58-year-old woman who was diagnosed at age 55 with a right infiltrating ductal carcinoma of the breast, identified as grade III, ER and PR positive, and HER2 positive. She had bilateral mastectomy, and tumor size was noted to be 2.8 cm. She had a positive sentinel lymph node. She was staged at IIB (pT2, pN1, M0). Her left breast was noted to have usual ductal epithelial hyperplasia and a 1.2 cm fibroadenoma. AS’s genetic testing revealed a BRCA1 mutation (BRCA1 c.3748G>T [p.Glu1250*]), which may confer an increased risk for breast cancer in the range of 46%–87%, and 39%–63% risk for ovarian cancer by age 70. As her patient history shows, she has some risk factors for nonadherence, including no support at home and some financial issues. Throughout her care, the team worked to communicate and prepare AS to help ensure adherence as much as possible.

The cancer treatment landscape has shifted with the emergence of new, targeted therapies. Development and use of oral oncolytics, targeted cancer therapies that can be taken by patients orally in their own homes, has increased in recent years. This increase is due in part to research in extra- and intracellular signaling pathways. By interfering with or blocking these signals, targeted drugs have become standard agents in cancer therapy. Oral oncolytics currently account for about 25% of the oncology pipeline of drugs in clinical development, and experts project that oral oncoloytic use will continue to rise.

Whereas chemotherapy induces apoptosis by interfering with cell division of both cancerous and healthy cells, targeted therapy exploits targets, proteins, enzymes, or genes specific to malignant cells through a variety of mechanisms of action, which helps prevent drug resistance. The agents work by either inhibiting angiogenesis, blocking chemical signals that tell cells to divide or carry out normal function, or delivering toxic substances to a cell.

On November 6, 2017, the U.S. Food and Drug Administration (FDA) granted regular approval to alectinib (Alecensa) for treatment of patients with anaplastic lymphoma kinase (ALK)-positive metastatic non-small cell lung cancer (NSCLC), as detected by an FDA-approved test.

A new three-in-one blood test that analyzes cancer DNA in the bloodstream before and during treatment will allow providers to understand and track which patients are likely to benefit from treatment with olaparib, a PARP inhibitor. Additionally, researchers found which genetic mutations prostate cancers use to resist treatment with olaparib. The study was published in Cancer Discovery.

On June 22, 2017, the U.S. Food and Drug Administration granted (FDA) regular approvals to dabrafenib and trametinib (Taflinar^® and Mekinist^®, Novartis Pharmaceuticals Inc.) administered in combination for patients with metastatic non-small cell lung cancer (NSCLC) with BRAF V600E mutation as detected by an FDA-approved test.

Oncology clinicians can expect to continue to see new targeted and immunotherapy drugs emerge as clinically approved agents in the fight against cancer. Five cancer-related U.S. Food and Drug Administration (FDA) approvals occurred in the first quarter of 2017; following are their indications for treatment and associated clinical implications. You’ll recognize that some of the agents were already FDA approved for other uses, but as clinical trials continue and new data emerge, clinical use is expanding to other disease sites and indications.

Results from a new clinical trial have shown that the targeted therapy drug ibrutinib, a BTK inhibitor, can effectively treat graft-versus-host disease (GVHD), a common complication from allogeneic stem cell transplants. The study findings were reported at the American Society of Hematology’s 2016 annual meeting.
