A new $100 million pilot program launched by the Department of Health and Human Services (HHS) offers state and community-based health care organizations the resources for prevention, testing, and treatment of hepatitis C among individuals with substance use disorder and serious mental illness, according to an HHS press release.

The program, known as the Hepatitis C Elimination Initiative Pilot, will be administered by the Substance and Mental Health Administration. “This program is designed to support communities severely affected by homelessness and to gain insights on effective ways to identify patients, complete treatment, cure infections, and reduce reinfection by hepatitis C,” according to the press release.

The upfront investment in hepatitis C management is projected to not only save lives, but also to save community health care costs in the long-term, according to the press release.

“This is a vigorous pilot program that provides the first steps toward the large goal of eliminating hepatitis C in the United States population,” said William Schaffner, MD, professor of infectious diseases at Vanderbilt University Medical Center, Nashville, Tennessee, in an interview.

Hepatitis C affects more than two million individuals in the US, and is often complicated by social and medical issues such as homelessness, substance abuse, and mental health issues, said Schaffner. Fortunately, hepatitis C can be treated with oral medications that cure the chronic viral infection, thereby ending ongoing liver injury and interrupting person-to-person transmission of the virus by sharing needles, he said.

Given that the population most affected with hepatitis C also is often homeless, with possible mental health issues and sharing of needles for illicit drug use, challenges in reaching this population include assuring them that the care they receive though this and other programs is nonjudgemental and helpful, Schaffner told GI & Hepatology News.

The oral medications that now can cure the chronic hepatitis C viral infections must be taken over a period of weeks, and patients who lead socially disorganized lives often need assistance to assure that the medicine is taken as intended, so trained and sensitive personnel who are committed to helping this population are needed to make treatment programs succeed, he said.

Looking ahead, “the purpose of the pilot studies that will be funded by this program is to explore various approaches to determine which are more successful in bringing patients in to be evaluated and then to complete treatment,” Schaffner added.

State and community-based organizations are among the entities eligible to apply for the program. Potential applicants can find information about the program and application materials on the SAMSHA website.

Schaffner had no financial conflicts to disclose.

The US Food and Drug Administration (FDA) has approved the immune checkpoint inhibitor cosibelimab (Unloxcyt; Checkpoint Therapeutics) for the treatment of adults with metastatic or locally advanced cutaneous squamous cell carcinoma (CSCC) who are not candidates for curative surgery or curative radiation. 

The programmed death ligand-1 (PD-L1)–blocking antibody is the first and only treatment of its kind approved for advanced CSCC, according to a Checkpoint Therapeutics press release. The FDA approval was based on findings from the multicenter, open-label Study CK-301-101 trial of 109 patients. 

In that trial, the objective response rate (ORR) was 47% in 78 patients with metastatic CSCC and 48% in 31 patients with locally advanced CSCC. Median duration of response (DOR) in treated patients was not reached in those with metastatic disease and was 17.7 months in those with locally advanced disease, according to the FDA approval notice.

Adverse reactions occurring in at least 10% of patients included fatigue, musculoskeletal pain, rash, diarrhea, hypothyroidism, constipation, nausea, headache, pruritus, edema, localized infection, and urinary tract infection.

The recommended treatment dose, according to the prescribing information, is 1200 mg given as an intravenous infusion over 60 minutes every 3 weeks until disease progression or unacceptable toxicity.

The agent offers “a differentiated treatment option versus available therapies by binding to PD-L1, rather than programmed death receptor-1 (PD-1), to release the inhibitory effects of PD-L1 on the anti-tumor immune response,” Checkpoint Therapeutics president and chief executive officer James Oliviero stated in the company press release. 

The agent has also “demonstrated the ability to induce antibody-dependent cell-mediated cytotoxicity, another potential differentiating feature of the drug compared to existing marketing therapies for CSCC,” Oliviero noted.

“CSCC is the second most common form of skin cancer, and those diagnosed with advanced disease that has recurred or metastasized face a poor prognosis,” stated Emily Ruiz, MD, academic director of the Mohs and Dermatologic Surgery Center at Brigham and Women’s Hospital and director of the High-Risk Skin Cancer Clinic at Dana-Farber Brigham Cancer Center. 

“With its dual mechanisms of action and compelling safety profile, this promising drug will provide US oncologists with an important new immunotherapy option for the treatment of CSCC,” she added.

Durvalumab (Imfinzi, AstraZeneca) is now approved for adults with limited-stage small cell lung cancer (LS-SCLC) whose disease has not progressed after treatment with concurrent platinum-based chemotherapy and radiation therapy.

The Food and Drug Administration approval makes the monoclonal antibody — which is already approved for multiple tumor types — the first immunotherapy regimen approved in this setting, AstraZeneca noted in a press release.

“Durvalumab is the first and only systemic treatment following curative-intent, platinum-based chemoradiotherapy to show improved survival for patients with this aggressive form of lung cancer,” international coordinating investigator on the trial, Suresh Senan, PhD, stated in the press release. “This finding represents the first advance for this disease in 4 decades.”

Approval, which followed Priority Review and Breakthrough Therapy Designation, was based on findings from the phase 3 ADRIATIC trial showing a 27% reduction in the risk for death with durvalumab vs placebo.

Findings from the trial were reported during a plenary session at the 2024 American Society of Clinical Oncology conference, and subsequently published in The New England Journal of Medicine.

In 730 patients with LS-SCLC who were randomized 1:1:1 to receive single-agent durvalumab, durvalumab in combination with tremelimumab, or placebo, overall survival (OS) and progression-free survival (PFS) were significantly improved with durvalumab alone vs placebo (hazard ratio, 0.73 and 0.76, for OS and PFS, respectively). Median OS was 55.9 months vs 33.4 months with durvalumab vs placebo, and PFS was 16.6 vs 9.2 months, respectively.

Senan, a professor of clinical experimental radiotherapy at the Amsterdam University Medical Center in the Netherlands, noted in the press release that 57% of patients were still alive at 3 years after being treated with durvalumab, which underscores the practice-changing potential of this medicine in this setting.

“This new treatment option is a game changer for patients with limited-stage small cell lung cancer, a disease known for its high rate of recurrence,” Dusty Donaldson, founder and executive director of the nonprofit advocacy organization LiveLung, stated in the release. “Historically, more often than not, clinical trials to identify new treatment options for this type of cancer have failed to show benefit. We are therefore so excited that many more people will now have the opportunity to access this immunotherapy treatment that holds the potential to significantly improve outcomes.”

Adverse reactions occurring in at least 20% of patients in the ADRIATIC trial included pneumonitis or radiation pneumonitis and fatigue.

The recommended durvalumab dose, according to prescribing information, is 1500 mg every 4 weeks for patients weighing at least 30 kg and 20 mg/kg every 4 weeks for those weighing less than 30 kg, until disease progression or unacceptable toxicity or a maximum of 24 months.

The Food and Drug Administration (FDA) has granted accelerated approval to zenocutuzumab-zbco (Bizengri, Merus) as an intravenous infusion for the treatment of certain adults with non–small cell lung cancer (NSCLC) or pancreatic adenocarcinoma.

Specifically, the systemic agent was approved for those with advanced, unresectable, or metastatic NSCLC or pancreatic adenocarcinoma harboring a neuregulin 1 (NRG1) gene fusion who progress on or after prior systemic therapy, according to the FDA.

The approval, based on findings from the multicenter, open-label eNRGy study, is the first from the FDA for a systemic therapy in this setting. In the multicohort study, treatment was associated with an overall response rate of 33% and 40% in 64 patients with NSCLC and 40 patients with pancreatic adenocarcinoma, respectively. Median duration of response was 7.4 months in the NSCLC patients and ranged from 3.7 to 16.6 months in those with pancreatic adenocarcinoma.

Adverse reactions occurring in at least 10% of patients included diarrhea, musculoskeletal pain, fatigue, nausea, infusion-related reactions, dyspnea, rash, constipation, vomiting, abdominal pain, and edema. Grade 3 or 4 laboratory abnormalities occurring in at least 10% of patients included increased gamma-glutamyl transferase and decreased hemoglobin, sodium, and platelets.

“The Personalized Medicine Coalition applauds the approval of BIZENGRI®,” Edward Abrahams, president of the Personalized Medicine Coalition, a Washington-based education and advocacy organization, stated in a press release from Merus. “In keeping with the growing number of personalized medicines on the market today, BIZENGRI® offers the only approved NRG1+ therapy for patients with these difficult-to-treat cancers.”

The agent is expected to be available for use in the “coming weeks,” according to Merus.

“The FDA approval of BIZENGRI® marks an important milestone for patients with pancreatic adenocarcinoma or NSCLC that is advanced unresectable or metastatic and harbors the NRG1 gene fusion,” noted Alison Schram, MD, an attending medical oncologist in the Early Drug Development Service at Memorial Sloan Kettering Cancer Center, New York City, and a principal investigator for the ongoing eNRGy trial. “I have seen firsthand how treatment with BIZENGRI® can deliver clinically meaningful outcomes for patients.”

Prescribing information for zenocutuzumab-zbco includes a Boxed Warning for embryo-fetal toxicity. The recommended treatment dose is 750 mg every 2 weeks until disease progression or unacceptable toxicity.

The Food and Drug Administration (FDA) has approved zanidatamab (Ziihera, Jazz Pharmaceuticals) as monotherapy for previously treated, unresectable or metastatic HER2-positive biliary tract cancer (BTC). This approval makes the bispecific antibody the first HER2-targeted treatment to carry the indication. 

Zanidatamab binds two separate regions on the HER2 cell surface protein, crosslinking neighboring HER2 proteins, blocking HER2 signaling, and inducing cytotoxic immune responses.

The FDA simultaneously announced that it has also approved VENTANA PATHWAY anti–HER2/neu (4B5) Rabbit Monoclonal Primary Antibody (Ventana Medical Systems, Inc./Roche Diagnostics) as a companion diagnostic device to aid in identifying patients with BTC who may be eligible for treatment with zanidatamab.

 

Zanidatamab Trial Results

The approval of zanidatamab was based on the phase 2b HERIZON-BTC-01 trial— which was open-label, multicenter, and single-arm — involving 62 patients with unresectable or metastatic HER2-positive (IHC3+) BTC. In this trial, zanidatamab 20 mg/kg was administered every 2 weeks to patients who had received gemcitabine-containing chemotherapy previously but not a HER2-targeted therapy.

The objective response rate was 52%, and the median duration of response was 14.9 months, according to the statement from the FDA.

The life expectancy for advanced BTC treated in the second line with standard chemotherapy is approximately 6-9 months, according to Jazz Pharmaceuticals. 

 

Boxed Warning and Adverse Events

The prescribing information contains a boxed warning for embryo-fetal toxicity. The most common adverse reactions reported in at least 20% of patients who received zanidatamab were diarrhea, infusion-related reactions, abdominal pain, and fatigue.

The recommended zanidatamab dose is 20 mg/kg, administered as an intravenous infusion once every 2 weeks until progression or unacceptable toxicity. 

Jazz Pharmaceuticals’ application was granted priority review, breakthrough therapy designation, and orphan drug designation.

An ongoing phase 3 trial, HERIZON-BTC-302, is testing zanidatamab in combination with standard-of-care therapy in the first-line setting for advanced or metastatic HER2-positive BTC. The bispecific antibody is also being developed for HER2-positive advanced/metastatic gastroesophageal adenocarcinoma.

A dermatophyte known as Trichophyton mentagrophytes genotype VII (TMVII) has been identified as the cause of an emerging sexually transmitted fungal infection in four adults in the United States, according to a paper published in the Centers for Disease Control and Prevention’s Morbidity and Mortality Weekly Report.

TMVII is a sexually transmitted fungus that causes genital tinea; the fungus might be misidentified as eczema, psoriasis, or other dermatologic conditions, Jason E. Zucker, MD, an infectious disease specialist at Columbia University Irving Medical Center, New York City, and colleagues wrote.

 

“Dermatophyte infections, including TMVII, are spread through direct skin-to-skin contact,” corresponding author Avrom S. Caplan, MD, a dermatologist at New York University Grossman School of Medicine, New York City, said in an interview.

“In the United States, to our knowledge, the infection has only been in MSM [men who have sex with men], but there have been reports of TMVII in Europe in non-MSM patients, including among patients who traveled to Southeast Asia for sex tourism or partners of people who have been infected with TMVII,” he said.

The four patients were diagnosed with tinea between April 2024 and July 2024, and fungal cultures and DNA sequencing identified TMVII as the cause of the infection. All four patients were cisgender men aged 30-39 years from New York City who reported recent sexual contact with other men; one was a sex worker, two had sex with each other, and one reported recent travel to Europe.

All four patients presented with rashes on the face, buttocks, or genitals; all were successfully treated with antifungals, the authors wrote.

Individuals with genital lesions who are sexually active should be seen by a healthcare provider, and TMVII should be considered, especially in the event of scaly, itchy, or inflamed rashes elsewhere on the body, Caplan told this news organization.

Additionally, “If someone presents for a medical evaluation and has ringworm on the buttocks, face, or elsewhere, especially if they are sexually active, the question of TMVII should arise, and the patient should be asked about possible genital lesions as well,” he said. “Any patient diagnosed with an STI [sexually transmitted infection], including MSM patients, should be evaluated appropriately for other STIs including TMVII.” 

Continued surveillance and monitoring are needed to track TMVII and to better understand emerging infections, Caplan told this news organization. Clinicians can find more information and a dermatophyte registry via the American Academy of Dermatology websites on emerging diseases in general and dermatophytes in particular.

“We also need better access to testing and more rapid confirmatory testing to detect emerging dermatophyte strains and monitor antifungal resistance patterns,” Caplan added. “At this time, we do not have evidence to suggest there is antifungal resistance in TMVII, which also distinguishes it from T indotineae.” 

 

Encourage Reporting and Identify New Infections

“Emerging infections can mimic noninfectious disease processes, which can make the diagnosis challenging,” Shirin A. Mazumder, MD, associate professor and infectious disease specialist at the University of Tennessee Health Science Center, Memphis, said in an interview.

“Monitoring emerging infections can be difficult if the cases are not reported and if the disease is not widespread,” Mazumder noted. Educating clinicians with case reports and encouraging them to report unusual cases to public health helps to overcome this challenge.

In the clinical setting, skin lesions that fail to respond or worsen with the application of topical steroids could be a red flag for TMVII, Mazumder told this news organization. “Since the skin findings of TMVII can closely resemble noninfectious processes such as eczema or psoriasis, the use of topical corticosteroids may have already been tried before the diagnosis of TMVII is considered.” 

Also, location matters in making the diagnosis. TMVII lesions occur on the face, genitals, extremities, trunk, and buttocks. Obtaining a thorough sexual history is important because the fungus spreads from close contact through sexual exposure, Mazumder added.

The most effective treatment for TMVII infections remains to be determined, Mazumder said. “Treatment considerations such as combination treatment with oral and topical antifungal medications vs oral antifungal medication alone is something that needs further research along with the best treatment duration.”

“Determining the rate of transmissibility between contacts, when someone is considered to be the most infectious, how long someone is considered infectious once infected, and rates of reinfection are questions that may benefit from further study,” she added.

Although the current cases are reported in MSM, determining how TMVII affects other patient populations will be interesting as more cases are reported, said Mazumder. “Further understanding of how different degrees of immunosuppression affect TMVII disease course is another important consideration.” 

Finally, determining the rate of long-term sequelae from TMVII infection and the rate of bacterial co-infection will help better understand TMVII, she said.

The researchers had no financial conflicts to disclose. Mazumder had no financial conflicts to disclose.
