Helicase–primase inhibitors for the treatment of herpes simplex virus infections – patent evaluation of WO2023/225162 from Gilead Sciences Inc

Review

作者: Kleymann, Gerald ; Gege, Christian

Helicase-primase is an interesting target for small-molecule therapy of herpes simplex virus (HSV) infections. With amenamevir already approved for varicella-zoster virus and herpes simplex in Japan and with pritelivir's granted breakthrough therapy designation for the treatment of acyclovir-resistant HSV infections in immunocompromised patients, the target has sparked interest in helicase-primase inhibitors (HPIs). Here, we analyze the first patent application from Gilead in this field, which pursued a me-too approach combining elements from an old Bayer together with a recent Medshine HPI application (which covers the Phaeno Therapeutics drug candidate HN0037). The asset was contributed to Assembly Biosciences, where it is under development as ABI-1179 at the investigational new drug (IND) enabling stage for high-recurrence genital herpes. A structure proposal for indolinoyl derivative ABI-1179 is presented, showing its potential opportunities and limitations compared to other HPIs.

Abstract:

Amenamevir is an oral once‐daily antiherpesvirus drug that can be administered without dose adjustment in patients with impaired renal function. There are currently no clinical data on immunocompromised patients with herpes zoster treated with amenamevir. Therefore, an exploratory study of the efficacy and safety of amenamevir against herpes zoster in patients with immunosuppression was conducted. Inclusion criteria included patients with acute herpes zoster receiving immunosuppressive drugs or those with malignant tumors or autoimmune diseases. Twenty‐four patients were included and received amenamevir (400 mg once daily after meals) for up to 14 days. The primary end point of overall improvement in skin symptoms 7 days after treatment initiation (day 7) was 58.3% for “markedly improved” and 20.8% for “improved.” The combined improvement rate was 79.2% (95% confidence interval, 57.8–92.9), and 20.8% of patients experienced “worsened” symptoms. The secondary end points of overall improvement in skin symptoms on day 14 and day 28 were 95.7% and 100%, respectively. The skin symptoms progressed during treatment, peaking on day 7, and then began to heal. By Kaplan–Meier estimation, the median periods to complete crusting and healing were both day 14. There were five adverse events with a possible causal relationship to amenamevir (bacterial skin infection, anemia, hyponatremia, headache, and abnormal liver function) in one of the 24 patients. Although the bacterial skin infection was severe, all events in this patient were reported to be either recovered or recovering. These findings indicate that amenamevir can be effective and safe in immunocompromised patients with herpes zoster. However, as worsening can happen around day 7, it is necessary to carefully monitor such patients and switch to other therapies such as intravenous acyclovir if necessary.Clinical trial identifier: Japan Registry of Clinical Trials jRCTs031190208.

Disproportionality analysis of amenamevir-induced encephalopathy using the Japanese adverse drug event report database

Article

作者: Ogawa, Taku ; Ashida, Akira ; Nishihara, Masami ; Yamada, Tomoyuki ; Tanaka, Tomoko ; Kusaka, Yusuke

INTRODUCTION:

Anti-herpesvirus drug-induced encephalopathy can complicate herpes zoster treatment; however, the association between the recently developed anti-herpesvirus drug amenamevir and encephalopathy development remains unknown. Determining the characteristics of amenamevir-induced encephalopathy is essential for potentially improving patient outcomes in the treatment of herpes zoster. The aim of this study is to identify the association between amenamevir treatment and encephalopathy and to determine the risk factors for amenamevir-induced encephalopathy via disproportionality analysis using the Japanese Adverse Drug Event Report (JADER) database.

METHOD:

We conducted a retrospective observational study using anonymized data from the JADER database. Encephalopathy was defined according to the Standardized Medical Dictionary for Regulatory Activities Queries specific to "Noninfectious encephalopathy/delirium." Disproportionality analysis was used to calculate the reporting odds ratios (RORs) and 95 % confidence intervals (CIs) to assess associations between amenamevir and encephalopathy. Multivariable logistic regression considered age, gender, chronic kidney disease, and cytochrome P450 3A inhibitor use as potential risk factors.

RESULTS:

Out of 713,316 patients, 246 were prescribed amenamevir. The median onset of encephalopathy in these patients was 3 days. Disproportionality of encephalopathy was observed in patients treated with amenamevir (ROR, 3.44; 95 % CI, 2.48-4.78). Furthermore, multivariable logistic regression analysis suggested that an age of ≥70 years was associated with amenamevir-induced encephalopathy (ROR, 7.63; 95 % CI, 2.25-25.9).

CONCLUSION:

These results suggest that amenamevir treatment may be associated with encephalopathy, particularly in patients aged ≥70 years. Healthcare providers should be aware of this potential risk, especially in elderly patients, to prevent severe central nervous system complications.

Maruho Receives Manufacturing and Marketing Approval for a Partial Change of the Indication and Dosage/Administration for Anti-herpes Virus Agent "Amenalief Tab. 200mg" for the Treatment of Recurrent Herpes Simplex in Japan

Osaka (Japan), February 24, 2023 - Maruho Co., Ltd. ("Maruho", Head Office: Osaka, Japan,President and CEO: Atsushi Sugita) announces that it has received manufacturing and marketing approval from the Ministry of Health, Labor and Welfare for a partial change of the indication and dosage/administration for anti-herpes virus agent "Amenalief® Tab. 200mg" (JAN/INN: amenamevir; hereinafter referred to as "the product") for the treatment of recurrent herpes simplex in Japan. Herpes simplex is a general term for infectious diseases caused by the herpes simplex virus that infects the skin and mucous membranes (lips, eyes, genitals, etc.). Common types include labial herpes and genital herpes. Recurrent herpes simplex is a disease that develops when the herpes simplex virus that has been latently infected in the ganglia after a primary infection, is reactivated by stimuli such as stress or a weakened immune system. Additionally, it is characterized by repeated recurrence of symptoms, and many patients experience discomfort such as itching and tingling before skin symptoms such as erythema (redness), papules and blisters develop. The partial change of the indication and dosage/administration approval received today is recognized as "Patient Initiated Treatment" (PIT) for patients with recurrent herpes simplex when they become aware of the initial symptoms.1) Early treatment is possible by taking the prescribed 1200mg of this drug once after meals within 6 hours after the appearance of the initial symptoms of recurrent herpes simplex. It is hoped that this drug will be more convenient for patients since only one dose is required. Maruho, specializing in dermatology, will strive to further contribute to patients and medical professionals by providing new options for the treatment of recurrent herpes simplex. Note The information contained in this news release in regard to pharmaceutical and developmental products is not intended for the purpose of promotion, advertising or medical advice.

Chemo Drug Potentially More Potent than Remdesivir Against Coronavirus

Researchers with Shenzhen Institutes of Advanced Technology in China used a variety of computational techniques to simulate drug-virus interactions. They then screened 1,906 existing drugs to evaluate which ones might inhibit replication of SARS-CoV-2, the virus that causes COVID-19. From this broad screening, they identified four drugs that had potential to prevent replication of the virus, which they then tested in laboratory experiments. Two of the drugs, pralatrexate, a chemotherapy, and azithromycin, an antibiotic, were successful at preventing replication of the virus. More lab experiments demonstrated that pralatrexate had stronger viral inhibition than Gilead Sciences’ remdesivir, which is currently the only approved drug for COVID-19. They published their research in the journal PLOS Computational Biology. Pralatrexate is marketed by Acrotech Biopharma under the trade name Folotyn. It is indicated for relapsed or refractory peripheral T-cell lymphoma. Like many chemotherapeutics, it comes with a wide range of serious side effects, including low blood cell counts—platelets, white blood cells, and red blood cells—mucositis, which is inflamed mucous membranes, severe skin reactions, tumor lysis syndrome (TLS), increased risk of serious reactions in kidney patients, fever, dehydration, nausea, as well as significant risk for pregnant and nursing women. As a result, the authors note that immediate use of the drug for COVID-19 patients is not guaranteed, but believe their approach was useful in identifying drugs that can be repurposed. “We have demonstrated the value of our novel hybrid approach that combines deep-learning technologies with more traditional simulations of molecular dynamics,” said Haiping Zhang, study author. The research team is working to develop more computational methods for creating novel molecular structures that could be developed into new drugs to treat COVID-19. The screening method focused on viral RNA-dependent RNA polymerase (RdRp), a promising therapeutic target. The authors write that other computational drug screening methods are based on molecular docking, deep learning or Molecular Dynamics. Most of these typically depend upon a single technique or lack experimental validation. “Each computation method,” they write, “with its underlying philosophy, often has its own strong and weak points, while a proper combination and modification of such methods could provide a better solution. Previously, we have developed two deep learning-based models to estimate protein-ligand interactions: DFCNN and DeepBindBC. DFCNN uses molecular vector data of protein pocket and ligand, instead of spatial information at interaction site, to estimate the protein-ligand pair as binding or non-binding with a probability value between 0 and 1. DeepBindBc estimates the binding possibility from atom contact information at interaction surface of a modelled 3D protein-ligand complex. The input of DeepBindBC contains spatial information of the protein-ligand interface, thus it strongly complements DFCNN.” Their hybrid screening procedure was made up of DFCNN, DeepBindBC, Autodoc Vina, pocket localized molecular dynamics simulation, metadynamics, and their own inhouse-developed tools. They screened potential drugs from the TargetMol-Approved_Drug_Library, which contains 1,906 currently marketed drugs. One of the findings, less focused on COVID-19, but of particular interest to validation of the screening approach, was that DFCNN, DeepBindBC and Autodock Vina predicted different drug compounds as top hits. For example, amenamevir and azithromycin had better scores on Autodock Vina, while odanacatib and nitisinone had higher DFCNN scores. Azithromycin, with hydroxychloroquine, an anti-malarial, had demonstrated efficacy in treating COVID-19 earlier in the pandemic, but subsequent studies have failed to show that either drug is effective in treating COVID-19. For that matter, a large World Health Organization (WHO) study failed to prove remdesivir’s effectiveness in hospitalized patients, resulting in the organization issuing a conditional recommendation against its use.
