An Open-Label, Single-Dose, Phase 1/2 Study to Evaluate the Pharmacokinetics, Safety, and Tolerability of Human Protein C (TAK-662) for the Treatment of Congenital Protein C Deficiency in Japanese Subjects Followed by an Extension Part

Pharmacokinetic Part:
This study is for Japanese participants with congenital protein C deficiency. The main aim of this study is to check how much TAK-662 stays in their blood over time. This will help the study sponsor (Takeda) to work out the best dose to give patients in the future.
Participants will receive 1 single infusion of TAK-662.
They will stay at the clinic until 3 days after the infusion. Then, participants will return to their clinic 7 days after the infusion to check side effects from the study treatment.
Extension Part:
Participants who will complete the PK part will be given an opportunity to continue TAK-662 administration as 3 different treatment options (on-demand therapy, short-term prophylaxis, and long-term prophylaxis) in the Extension part, until the commercial protein C concentrate is available at each study site or study termination.

Administration of Protein C Concentrates in Adult Critically Ill Septic Patients

Severe sepsis and septic shock are life threatening medical emergencies and are among the most significant challenges in critical care. Case reports and case series suggest that plasma-derived protein C concentrate may improve the outcome of patients with acquired protein C deficiency. Evidence has accumulated on the clinical relevance of the PC pathway in modulating overwhelming inflammation and preventing coagulation derangements, two key mediators of organ damage, and thus of mortality and morbidity, in sepsis. The experience collected through these studies shows that PC is safe, in that it is not associated with bleeding or severe allergic complications,and possibly useful, at least to improve the coagulation abnormalities brought about by sepsis. Unfortunately, however, all we know comes from case series or case reports or an underpowered randomized controlled study. A randomized clinical trial, adequately powered for mortality or clinically relevant outcome, is necessary to confirm PC efficacy.The aim of this study is to demonstrate that Protein C zymogen has clinically relevant implications in terms of reduction of thromboembolic events, 30 days mortality, length of intensive care and hospital stay, time on mechanical ventilation, length of ICU and hospital stay. The study will also confirm that there is no bleeding concern with the use of Protein C concentrates.The study drug will be administered in the Intensive Care Unit for 72 hours and the patients observed till ICU discharge. Telephone followup will be performed at 30 days and at one year.

HIV-1 latency reversal agent boosting is not limited by opioid use.

The opioid epidemic may impact the HIV-1 reservoir and its reversal from latency in virally suppressed people with HIV (PWH). We studied forty-seven PWH and observed that lowering the concentration of HIV-1 latency reversal agents (LRA), used in combination with small molecules that do not reverse latency, synergistically increases the magnitude of HIV-1 re-activation ex vivo, regardless of opioid use. This LRA boosting, which combines a Smac mimetic or low-dose protein kinase C agonist with histone deacetylase inhibitors, can generate significantly more unspliced HIV-1 transcription than phorbol 12-myristate 13-acetate (PMA) with ionomycin (PMAi), the maximal known HIV-1 reactivator. LRA boosting associated with greater histone acetylation in CD4⁺ T cells and modulated T cell activation-induced markers and intracellular cytokine production; Smac mimetic-based boosting was less likely to induce immune activation. We found that HIV-1 reservoirs in PWH contain unspliced and polyadenylated (polyA) virus mRNA, the ratios of which are greater in resting than total CD4⁺ T cells and can correct to 1:1 with PMAi exposure. Latency reversal results in greater fold-change increases to HIV-1 poly(A) mRNA than unspliced message. Multiply spliced HIV-1 transcripts and virion production did not consistently increase with LRA boosting, suggesting the presence of a persistent post-transcriptional block. LRA boosting can be leveraged to probe the mechanisms of an effective cellular HIV-1 latency reversal program.

Thrombosis questions from the inpatient wards

Review

作者: Goshua, George ; Lee, Alfred Ian ; Bendapudi, Pavan K.

Abstract:

The multifaceted pathophysiologic processes that comprise thrombosis and thromboembolic diseases take on a particular urgency in the hospitalized setting. In this review, we explore 3 cases of thrombosis from the inpatient wards: purpura fulminans, cancer-associated thrombosis with thrombocytopenia, and coronavirus disease 2019 (COVID-19) and the use of dose-escalated anticoagulation therapy and antiplatelet agents. We discuss the evaluation and management of purpura fulminans and the roles of plasma transfusion, protein C and antithrombin replacement, and anticoagulation in treating this disease. We present a framework for evaluating the etiologies of thrombocytopenia in cancer and review 2 strategies for anticoagulation management in patients with cancer-associated thrombosis and thrombocytopenia, including recent prospective data supporting the use of dose-modified anticoagulation based on platelet count. Last, we dissect the major clinical trials of therapeutic- and intermediate-dose anticoagulation and antiplatelet therapy in hospitalized patients with COVID-19, reviewing key recommendations from consensus guidelines while highlighting ways in which institutional and patient-tailored practices regarding antithrombotic therapies in COVID-19 may differ. Together, the cases highlight the diverse and dramatic presentations of macro- and microvascular thrombosis as encountered on the inpatient wards.

Meeting highlights from the Committee for Medicinal Products for Human Use (CHMP) 7-10 November 2022

Four new medicines recommended for approval EMA’s human medicines committee ( CHMP ) recommended four medicines for approval at its November 2022 meeting. The CHMP recommended authorising the COVID-19 vaccine VidPrevtynBeta (COVID-19 vaccine (recombinant, adjuvanted)) as a booster in adults previously vaccinated with an mRNA or adenoviral vector COVID-19 vaccine. It is the seventh vaccine recommended in the European Union (EU) for protecting against COVID-19 and, together with the vaccines already authorised, will support vaccination campaigns in EU Member States during the pandemic. See more information in the news announcement in the grid below. The committee adopted a positive opinion for a biosimilar medicine , Kauliv (teriparatide), for the treatment of osteoporosis, a health condition that weakens bones, making them fragile and more likely to break. A generic medicine , Pirfenidone Viatris (pirfenidone), received a positive opinion for the treatment of idiopathic pulmonary fibrosis, a chronic and progressive condition in which the lungs become scarred and breathing becomes increasingly difficult. The CHMP adopted a positive opinion for a generic medicine , Sugammadex Amomed (sugammadex), intended for the reversal of neuromuscular blockade induced by rocuronium in adults and children or vecuronium in adults. Rocuronium and vecuronium are muscle relaxants used during some types of surgeries. Sugammadex is used to speed up the recovery from the effects of the muscle relaxant. Recommendations on extensions of therapeutic indication for 11 medicines The committee recommended 11 extensions of indication for medicines that are already authorised in the EU: Ceprotin , Comirnaty , DuoPlavin , Dupixent , Enhertu , Eylea , Imfinzi , Iscover , Lynparza , Plavix and Xofluza . Withdrawals of applications Two applications for marketing authorisation were withdrawn: Orepaxam * for the treatment of pulmonary arterial hypertension, and Febseltiq * for the treatment of cholangiocarcinoma (cancer of the bile ducts). Two applications for extensions of therapeutic indications were withdrawn: Gavreto for the treatment of certain types of thyroid cancer, and Ilaris for the treatment of Schnitzler syndrome, a rare inflammatory disease causing long-term urticaria, recurrent fever, bone and joint pain, and swollen lymph nodes. Question-and-answer documents on the withdrawals are available in the grid below. COVID-19 update The committee recommended extending the use of COVID-19 vaccine Comirnaty targeting the original strain and Omicron subvariants BA.4 and BA.5 in children between 5 to 11 years of age. An overview of all the COVID-19 vaccines authorised in the EU is available on EMA’s website. Safety update The CHMP endorsed the measures recommended by the Pharmacovigilance Risk Assessment Committee ( PRAC ) to minimise the risk of serious side effects with Janus kinase (JAK) inhibitors used to treat several chronic inflammatory disorders. These side effects include cardiovascular conditions, blood clots, cancer and serious infections. This recommendation is the outcome of an article 20 referral procedure, which is triggered for medicines that have been authorised via the centralised procedure in case ofquality, safety or efficacy issues. A public health communication on this referral is available in the grid below. Agenda and minutes The agenda of the November 2022 CHMP meeting is published on EMA's website. Minutes of the October 2022 CHMP meeting will be published in the coming weeks. CHMP statistics Key figures from the November 2022 CHMP meeting are represented in the graphic below. *This product was designated as an orphan medicine during its development. Orphan designations are reviewed by EMA's Committee for Orphan Medicinal Products ( COMP ) at the time of approval to determine whether the information available to date allows maintaining the medicine’s orphan status and granting the medicine ten years of market exclusivity .
