Testing of HIV Protease Inhibitors to Suppress Inflammation and Improve Cardio Pulmonary Hemodynamics in Subjects With Pulmonary Arterial Hypertension

Study Rationale:There is recent evidence that HIV protease inhibitors (HIV-PI) can improve pulmonary hemodynamics in experimental models of pulmonary arterial hypertension (PAH). There is also experimental evidence that both TLR4 and high mobility group box 1 (HMGB1) participate in the pathogenesis of experimental pulmonary hypertension. A recent high throughput screen for inhibitors of HMGB1 induced macrophage activation yielded HIV-protease inhibitors (PIs) as potent inhibitors of HMGB1 induced cytokine production. Based on the experimental evidence we propose a trial to determine whether HIV-PIs will alter the pathobiology of PAH.
Study Objectives:The main objective of this study is to determine whether saquinavir and ritonavir (SQV+RIT) which have a well-characterized safety profile in humans will reduce bio markers of inflammation and pulmonary artery pressures in patients with PAH.
Study Hypothesis:We hypothesize that the HIV-PI, SQV+RIT, will reduce circulating parameters of inflammation including HMGB1, IL1-beta, IL-6, IL-8, IL-10, TNF-alpha and CRP. Our end points will be changes in these parameters from baseline over the duration of the study.We hypothesize that treatment with SQV+RIT will reduce pulmonary artery(PA) pressure of patients with PAH as measured by echocardiography.
Study Design:This is a single center open label phase 0 study to evaluate the effect of SQV +RIT in patients with IPAH. Subjects with IPAH(N=20) will be enrolled into a study, which will be divided into 3 cohorts and entail the administration of HIV protease inhibitors in three doses. The first cohort (n=3) will receive a starting dose of SQV 0.3 mg/kg twice daily in combination with RIT 0.03 mg/kg twice daily. If the first dose is well-tolerated, the second cohort (n= 3 ) with IPAH will be given doses of SQV 3 mg/kg and RIT 0.3 mg/kg twice daily. If the second dose is well-tolerated, the last cohort (n= 14 ) with IPAH will be given doses of SQV 15 mg/kg and RIT 1.5 mg/kg twice daily.

Repurposing HIV protease inhibitors as senotherapeutic agents in cervical cancer: Dual targeting of CDK1/6-cell cycle arrest and p53/p21/p16 signaling axis

Article

作者: Sun, Shiguo ; Li, Hongjuan ; Han, Weiqiang ; Yu, Lan ; Liu, Guoxin ; Liu, Fengyu ; Zhang, Jing ; Xu, Yongqian

The clinical management of cervical cancer remains constrained by limited therapeutic options and a paucity of targeted pharmacological interventions. Drug repurposing emerges as a promising strategy to expedite oncological therapeutics development. This study systematically investigates the antineoplastic potential of HIV protease inhibitors saquinavir (SQV) and tipranavir (TPV) through multimodal mechanistic validation. In vitro analyses demonstrated dose-dependent inhibition of cervical cancer cell proliferation accompanied by significant upregulation of senescence-associated β-galactosidase (SA-β-Gal) activity. Molecular characterization revealed concomitant activation of senescence-regulatory proteins p53, p21, and p16, suggesting induction of tumor-suppressive senescence pathways. Transcriptomic profiling of inhibitor-treated SiHa cells identified critical cell cycle regulators CDK1 and CDK6, findings corroborated by molecular docking simulations revealing high-affinity binding to cyclin-dependent kinases (-32.0607 to -47.6820 kJ/mol). In vivo validation using xenograft models demonstrated comparable tumor growth inhibition to doxorubicin with preserved host viability and negligible systemic toxicity. Mechanistic integration revealed dual pathway modulation: G1-phase cell cycle arrest mediated through CDK1/6 suppression and coordinated activation of the p53/p21/p16 senescence signaling axis. These findings establish SQV and TPV as multi-targeted senotherapeutic agents, providing preclinical rationale for repurposing HIV antivirals as novel therapeutic strategy against cervical malignancies.

A deep drug prediction framework for viral infectious diseases using an optimizer-based ensemble of convolutional neural network: COVID-19 as a case study

Article

作者: Babu, K R Remesh ; Deepthi, K ; Aruna, A S ; Babu, K. R. Remesh ; Aruna, A. S. ; Deepthi, K.

The SARS-CoV-2 outbreak highlights the persistent vulnerability of humanity to epidemics and emerging microbial threats, emphasizing the lack of time to develop disease-specific treatments. Therefore, it appears beneficial to utilize existing resources and therapies. Computational drug repositioning is an effective strategy that redirects authorized drugs to new therapeutic purposes. This strategy holds significant promise for newly emerging diseases, as drug discovery is a lengthy and expensive process. Through this study, we present an ensemble method based on the convolutional neural network integrated with genetic algorithm and deep forest classifier for virus-drug association prediction (CGDVDA). We generated feature vectors by combining drug chemical structure and virus genomic sequence-based similarities, and extracted prominent deep features by applying the convolutional neural network. The convoluted features are optimized using the genetic algorithm and classified using the ensemble deep forest classifier to predict novel virus-drug associations. The proposed method predicts drugs for COVID-19 and other viral diseases in the dataset. The model could achieve ROC-AUC scores of 0.9159 on fivefold cross-validation. We compared the performance of the model with state-of-the-art approaches and classifiers. The experimental results and case studies illustrate the efficacy of CGDVDA in predicting drugs against viral infectious diseases.

Abstract:

Objectives:

This study aimed to evaluate the prevalence and characteristics of drug resistance mutations (DRMs) in patients with low-level viremia (LLV) in Southwestern China, as it has become a growing challenge in AIDS clinical practice.

Methods:

This cross-sectional study was performed in Yunnan Province, Southwestern China. LLV was defined as 50–999 copies/mL of plasma viral load with antiretroviral therapy (ART) for at least 6 months. HIV-1 DRM detection used validated in-house protocol.

Results:

A total of 470 sequences were obtained, and 13 HIV-1 genotypes were identified, among which CRF08_BC (47.5%), CRF07_BC (22.3%) and CRF01_AE (10.0%) subtypes were the most prevalent. The overall prevalence of DRMs was 45.7% (215/470), and the prevalence of DRMs to non-nucleoside reverse transcriptase inhibitors (NNRTIs), nucleoside reverse transcriptase inhibitors (NRTIs) and protease inhibitors (PIs) was 39.4% (185/470), 20.6% (97/470) and 5.3% (25/470), respectively. The most common NNRTI-associated mutations were K103N (16.0%), E138A (6.6%), V179D (6.6%) and P225H (4.9%), and those in NRTIs were M184V (17.0%), D67N (3.4%) and K65R (3.0%). PI-associated mutations were infrequent, occurring in less than 1.8% of cases. The prevalence of NNRTI-associated mutations (K101E and Y188C) was found to be statistically significant among various LLV groups. Additionally, significant variations were observed in the prevalence of NNRTI-associated mutations (V106I, V106M, E138A and P225H), NRTI-associated mutation (K65R) and PI-associated mutations (L33F and Q58E) across different subtypes.

Conclusions:

The prevalence of DRMs in ART-experienced patients with LLV was high, and HIV-1 genotypes exhibited diversity in Yunnan Province. These findings indicate that regular DRM monitoring during LLV episodes was essential for effective clinical treatment and management in this region.

INDICATION TARPEYO is indicated to reduce the loss of kidney function in adults with primary immunoglobulin A nephropathy (IgAN) who are at risk for disease progression. IMPORTANT SAFETY INFORMATION CONTRAINDICATIONS TARPEYO is contraindicated in patients with hypersensitivity to budesonide or any of the ingredients of TARPEYO. Serious hypersensitivity reactions, including anaphylaxis, have occurred with other budesonide formulations. WARNINGS AND PRECAUTIONSHypercorticism and adrenal axis suppression: When corticosteroids are used chronically, systemic effects such as hypercorticism and adrenal suppression may occur. Corticosteroids can reduce the response of the hypothalamus-pituitary-adrenal (HPA) axis to stress. In situations where patients are subject to surgery or other stress situations, supplementation with a systemic corticosteroid is recommended. When discontinuing therapy or switching between corticosteroids, monitor for signs of adrenal axis suppression. Patients with moderate to severe hepatic impairment (Child-Pugh Class B and C respectively) could be at an increased risk of hypercorticism and adrenal axis suppression due to an increased systemic exposure to oral budesonide. Avoid use in patients with severe hepatic impairment (Child-Pugh Class C). Monitor for increased signs and/or symptoms of hypercorticism in patients with moderate hepatic impairment (Child-Pugh Class B). Immunosuppression and Increased Risk of Infection: Corticosteroids, including TARPEYO, suppress the immune system and increase the risk of infection with any pathogen, including viral, bacterial, fungal, protozoan, or helminthic pathogens. Corticosteroids can: reduce resistance to new infections, exacerbate existing infections, increase the risk of disseminated infections, increase the risk of reactivation or exacerbation of latent infections, and mask some signs of infection. Corticosteroid-associated infections can sometimes be serious. Monitor for infection and consider TARPEYO withdrawal as needed. Avoid corticosteroid therapy, including TARPEYO, in patients with active or quiescent tuberculosis or hepatitis B infection; untreated fungal, bacterial, systemic viral, or parasitic infections; ocular herpes simplex; or Kaposi’s sarcoma. Avoid exposure to active, easily-transmitted infections (e.g., chickenpox, measles). Corticosteroid therapy may decrease the immune response to some vaccines. Other corticosteroid effects: TARPEYO is a systemically available corticosteroid and is expected to cause related adverse reactions. Monitor patients with hypertension, prediabetes, diabetes mellitus, osteoporosis, peptic ulcer, glaucoma or cataracts, or with a family history of diabetes or glaucoma, or with any other condition where corticosteroids may have unwanted effects. ADVERSE REACTIONS In clinical studies, the most common adverse reactions with TARPEYO (occurring in ≥5% of TARPEYO treated patients, and ≥2% higher than placebo) were peripheral edema (17%), hypertension (12%), muscle spasms (12%), acne (11%), headache (10%), upper respiratory tract infection (8%), face edema (8%), weight increased (7%), dyspepsia (7%), dermatitis (6%), arthralgia (6%), and white blood cell count increased (6%). DRUG INTERACTIONS Budesonide is a substrate for CYP3A4. Avoid use with potent CYP3A4 inhibitors, such as ketoconazole, itraconazole, ritonavir, indinavir, saquinavir, erythromycin, and cyclosporine. Avoid ingestion of grapefruit juice with TARPEYO. Intake of grapefruit juice, which inhibits CYP3A4 activity, can increase the systemic exposure to budesonide. USE IN SPECIFIC POPULATIONSPregnancy: The available data from published case series, epidemiological studies, and reviews with oral budesonide use in pregnant women have not identified a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. There are risks to the mother and fetus associated with IgAN. Infants exposed to in-utero corticosteroids, including budesonide, are at risk for hypoadrenalism. Please see Full Prescribing Information. About TARPEYOTARPEYO is an oral 4mg delayed release formulation of budesonide, designed to remain intact until it reaches the ileum. Each capsule contains coated beads of budesonide that target mucosal B-cells present in the ileum, including the Peyer’s patches, which are responsible for the production of galactose-deficient IgA1 antibodies (Gd-Ag1) causing IgA nephropathy. About Primary Immunoglobulin A NephropathyPrimary immunoglobulin A nephropathy (IgA nephropathy or IgAN or Berger’s Disease) is a rare, progressive, chronic autoimmune disease that attacks the kidneys and occurs when galactose deficient IgA1 is recognized by autoantibodies, creating IgA1 immune complexes that become deposited in the glomerular mesangium of the kidney. This deposition in the kidney can lead to progressive kidney damage and potentially a clinical course resulting in end- stage renal disease. IgAN most often develops between late teens and late 30s.

Petros Pharmaceuticals Successfully Completes AI-Integrated Formative Human Factors Study Demonstrating Positive Interaction with Web App Designed for STENDRA(R) (avanafil) OTC Switch

Study paves the way toward a first-ever innovation program to include AI-optimization for FDA-guided Rx-to-OTC switch NEW YORK, NY / ACCESSWIRE / May 29, 2024 / Petros Pharmaceuticals, Inc. (NASDAQ:PTPI) ("Petros" or the "Company"), a company focused on expanding consumer access to medication through over-the-counter ("OTC") drug development programs, announces the successful completion of a Formative Human Factors study of its AI-integrated Web App, designed to facilitate OTC access of STENDRA® (avanafil) for consumers. This important development follows the Company's recent execution of an AI licensing agreement with a leading multi-billion dollar software provider announced earlier this year. The Web App (previously referred to as the "technology component") is an integral part of the Company's efforts to complete an Rx-to-OTC switch for STENDRA® (avanafil) under the guidance of the U.S. Food and Drug Administration. The study demonstrated a 90% or better error-free completion rate for nearly all 5,820 tasks assessed. The successful completion of the study paves the way for the Company to initiate the next stage of the evolving program, while continuing to optimize the AI component of the Web App. "The successful completion of the Human Factors Study and the positive outcomes we've seen to date continue to be encouraging signs of our progress in navigating the Rx-to-OTC switch for STENDRA® (avanafil). As we've previously indicated, we believe we have the potential to be first-in-class for the category with regards to OTC access," stated Fady Boctor, Petros' President and Chief Commercial Officer. "We continue to refine our program based on our regular interactions with the FDA, and the learnings from this study will allow us to continue to optimize the AI component of the Web App. Combined, we strongly believe in our approach and look forward to continuing development into the next indicated step for STENDRA® (avanafil) in a non-prescription setting." The Formative Human Factors study was conducted in a population of 30 consumers, including a cohort with limited literacy. The consumers were provided with five different use scenarios requiring correct demonstration of 194 different tasks using the Web App with no training or guidance. The study also included a proprietary AI interface that confirmed the identity of the consumer, a first-ever innovation for an Rx-to-OTC switch program. About Petros Pharmaceuticals Petros Pharmaceuticals, Inc. is committed to the goal of becoming a leading innovator in the emerging self-care market driving expanded access to key prescription pharmaceuticals as OTC treatment options. Currently, Petros is pursuing increased access for its flagship prescription ED therapy, STENDRA® (avanafil), via potential OTC designation. If ultimately approved by the FDA for OTC access, STENDRA® (avanafil) may be the first in its class to achieve this marketing status, also establishing company know how as a proven platform for other prospective prescription therapeutics. About the OTC Pathway The process of switching a prescription medication to OTC first involves the design of a Drug Facts Label ("DFL") that is well understood by potential consumers. Then, data must show that consumers can make an appropriate informed decision to use or not to use the product based only upon the information on the DFL and their personal medical history. Then consumers must demonstrate that they can properly use the product based upon the information on the DFL. To accomplish this, the FDA ordinarily requires a consumer tested OTC DFL. Such testing includes conduct of iterative Label Comprehension Studies (LCS) in the general population, Self-Selection Studies (SSS) in a population interested in using the product and in specific populations who may be harmed if they use the product, and usually one Actual Use Trial (AUT) demonstrating safe and appropriate use by consumers in a simulated OTC setting. The regulations that FDA is currently finalizing introduced Additional Conditions for Nonprescription Use (ACNU) criteria that enable correct self-selection by consumers and may expand OTC access to medications that formerly could only be available by prescription. An ACNU may be an innovative computerized tool, or the additional conditions may use other approaches that support the switch process. Important Safety Information about STENDRA® (avanafil) STENDRA® (avanafil), originally launched by Auxilium Pharmaceuticals prior to its sale to Endo Pharmaceuticals, is an oral phosphodiesterase 5 (PDE5) inhibitor for the treatment of erectile dysfunction. STENDRA® (avanafil) is not for use in women or children. It is not known if STENDRA® (avanafil) is safe and effective in women or children under 18 years of age. A 100-mg and 200-mg tablet can be taken as early as ~15 minutes before sexual activity. STENDRA® (avanafil) only works with sexual stimulation and should not be taken more than once a day. STENDRA can be taken with or without food; do not drink too much alcohol when taking STENDRA® (avanafil) (for example, more than three glasses of wine or three shots of whiskey) as it can increase chances of side effects. Of people enrolled in clinical trials, 1.4%, 2.0%, and 2.0%, respectively, stopped taking STENDRA® (avanafil) (50 mg, 100 mg, or 200 mg) due to side effects compared to 1.7% taking a placebo. STENDRA® (avanafil) was designed and developed expressly for erectile dysfunction. STENDRA is contraindicated for any form of organic nitrates, in patients with known hypersensitivity to any component of the tablet, and in patients who are using a guanylate cyclase stimulator. Patients should not use STENDRA if sexual activity is inadvisable due to cardiovascular status or any other reason. Before taking STENDRA, tell your doctor if you have had any kind of heart issues including heart attack, heart failure, angina and irregular heartbeat or have elevated or low blood pressure. Use of STENDRA with alpha-blockers, other antihypertensives, or substantial amounts of alcohol (greater than three units) may lead to hypotension. Patients should seek emergency treatment if an erection lasts greater than 4 hours. Patients should stop STENDRA and seek medical care if a sudden loss of vision occurs in one or both eyes, which could be a sign of Non-Arteritic Ischemic Optic Neuropathy ("NAION"). Doctors should discuss with patients the increased risk of NAION in patients with a history of NAION. Patients should stop taking STENDRA and seek prompt medical attention in the event of sudden decrease or loss of hearing. STENDRA can potentiate the hypotensive effect of nitrates, alpha blockers, antihypertensives, and alcohol. CYP3A4 inhibitors (e.g., ketoconazole, ritonavir, erythromycin) increase STENDRA exposure. For patients taking concomitant strong CYP3A4 inhibitors (including ketoconazole, ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir and telithromycin), do not use STENDRA. Combination with Other PDE5 Inhibitors or Erectile Dysfunction Therapies is not recommended. The safety of STENDRA is unknown in patients with bleeding disorders and patients with active peptic ulceration. The use of STENDRA offers no protection against sexually transmitted diseases including HIV. Consider counseling patients on protective measures for sexually transmitted diseases. The most common adverse reactions reported with use of STENDRA include headache, flushing, nasal congestion, nasopharyngitis, and back pain. For more information about STENDRA, call 844-458-4887.
