Deucravacitinib, a selective, allosteric tyrosine kinase 2 inhibitor, in scalp psoriasis: A subset analysis of two phase 3 randomized trials in plaque psoriasis

BACKGROUND

Scalp involvement in plaque psoriasis is challenging to treat.

OBJECTIVE

To evaluate the efficacy and safety of deucravacitinib (DEUC) in scalp psoriasis.

METHODS

POETYK PSO-1 and PSO-2 were global phase 3, 52-week, double-blinded trials in adults with moderate to severe psoriasis. Patients were randomized 1:2:1 to oral placebo, DEUC 6 mg once daily, or apremilast 30 mg twice daily. This pooled secondary analysis evaluated scalp-specific Physician Global Assessment score of 0 or 1 (0/1), ≥90% improvement from baseline in Psoriasis Scalp Severity Index, and change from baseline in Psoriasis Scalp Severity Index. Adverse events were evaluated through week 16.

RESULTS

Overall, 1084 patients with moderate to severe scalp psoriasis at baseline were included. At week 16, response rates were greater with DEUC versus placebo or apremilast for scalp-specific Physician Global Assessment 0/1 (64.0% vs 17.3% vs 37.7%; P < .0001), ≥90% improvement from baseline in Psoriasis Scalp Severity Index (50.6% vs 10.5% vs 26.1%; P < .0001), and change from baseline in Psoriasis Scalp Severity Index. Responses were maintained through 52 weeks with continuous DEUC. Safety was consistent with the entire study population.

LIMITATIONS

Lack of data in milder scalp psoriasis.

CONCLUSION

DEUC was significantly more efficacious than placebo or apremilast in improving moderate to severe scalp psoriasis and was well tolerated.

Deucravacitinib in moderate-to-severe plaque psoriasis: Pooled safety and tolerability over 52 weeks from two phase 3 trials (POETYK PSO-1 and PSO-2)

BACKGROUND

Two phase 3 trials, POETYK PSO-1 and PSO-2, previously established the efficacy and overall safety of deucravacitinib, an oral, selective, allosteric tyrosine kinase 2 (TYK2) inhibitor, in plaque psoriasis.

OBJECTIVES

To further assess the safety of deucravacitinib over 52 weeks in the pooled population from these two trials.

METHODS

Pooled safety data were evaluated from PSO-1 and PSO-2 in which patients with moderate-to-severe plaque psoriasis were randomized 1:2:1 to receive oral placebo, deucravacitinib or apremilast.

RESULTS

A total of 1683 patients were included in the pooled analysis. Adverse event (AE) incidence rates were similar in each treatment group, serious AEs were low and balanced across groups, and discontinuation rates were lower with deucravacitinib versus placebo or apremilast. No new safety signals emerged with longer deucravacitinib treatment. Exposure-adjusted incidence rates of AEs of interest with placebo, deucravacitinib and apremilast, respectively, were as follows: serious infections (0.8/100 person-years [PY], 1.7/100 PY, and 1.8/100 PY), major adverse cardiovascular events (1.2/100 PY, 0.3/100 PY, and 0.9/100 PY), venous thromboembolic events (0, 0.2/100 PY, and 0), malignancies (0, 1.0/100 PY and 0.9/100 PY), herpes zoster (0.4/100 PY, 0.8/100 PY, and 0), acne (0.4/100 PY, 2.9/100 PY, and 0) and folliculitis (0, 2.8/100 PY, and 0.9/100 PY). No clinically meaningful changes from baseline in mean levels, or shifts from baseline to CTCAE grade ≥3 abnormalities, were reported in laboratory parameters with deucravacitinib.

CONCLUSIONS

Deucravacitinib was well-tolerated with acceptable safety over 52 weeks in patients with psoriasis.

Deucravacitinib, an oral, selective, allosteric tyrosine kinase 2 inhibitor, in Japanese patients with moderate to severe plaque, erythrodermic, or generalized pustular psoriasis: Efficacy and safety results from an open-label, phase 3 trial

Deucravacitinib, an oral, selective, allosteric tyrosine kinase 2 inhibitor, is approved in Japan for adult patients with plaque (PP), generalized pustular (GPP), and erythrodermic (EP) psoriasis who have had an inadequate response to conventional systemic therapies. This approval is based on results from the global phase 3 POETYK PSO-1 and PSO-2 trials in which deucravacitinib was associated with significantly improved efficacy outcomes compared with placebo in adults with moderate to severe plaque psoriasis, and results described here from POETYK PSO-4, an open-label, single-arm, phase 3 trial (NCT03924427), which evaluated the efficacy and safety of deucravacitinib 6 mg once daily in adult Japanese patients with PP, GPP, or EP. The coprimary endpoints were the proportion of patients achieving a ≥75% reduction from baseline in the Psoriasis Area and Severity Index (PASI 75) and a static Physician's Global Assessment score of 0 (clear) or 1 (almost clear) (sPGA 0/1) with at least a two-point improvement from baseline at week 16. Nonresponder imputation was used for missing data. Efficacy responses, adverse events (AEs), and serious AEs (SAEs) were recorded for up to 52 weeks. Seventy-four patients were treated (PP, n = 63; GPP, n = 3; EP, n = 8). At week 16, 76.2%, 66.7%, and 37.5% of patients with PP, GPP, and EP, respectively, had achieved PASI 75, and 82.5%, 0.0%, and 50.0% had achieved sPGA 0/1. Responses were overall maintained through week 52. AEs occurred in 74.6% of patients with PP, 100% of patients with GPP, and 87.5% of patients with EP. The most common AEs were nasopharyngitis and acne. Rates of SAEs and discontinuations were low. There were no deaths. Deucravacitinib was effective and well tolerated in Japanese patients with moderate to severe PP and in a limited number of patients with GPP or EP.

Treatment of plaque psoriasis with deucravacitinib (POETYK PSO-2 study): a plain language summary

WHAT IS THIS SUMMARY ABOUT?

This is a summary of a paper published in a medical journal that describes the results of a study called POETYK PSO-2, which investigated a new treatment for plaque psoriasis. Plaque psoriasis appears on the body as dry, discolored, patches of skin that can be flaky and covered in scales. This can make the skin itch, crack or bleed and make it difficult for people with psoriasis to perform basic everyday tasks. Treatments are available, but some do not always reduce symptoms or may need to be injected or taken multiple times a day, which can be difficult to do, or can have undesirable side effects. Researchers are looking for new treatments for psoriasis.

WHAT HAPPENED IN THE STUDY?

Deucravacitinib is a once-daily pill taken by mouth (orally) that was studied as a treatment for moderate to severe plaque psoriasis in two large studies conducted globally, PSO-1 and PSO-2. POETYK PSO-2 was a Phase 3 research study, which is a study that tests a treatment in a large group of participants, that looked at how well deucravacitinib worked in participants with moderate to severe plaque psoriasis compared to a placebo (an inactive pill that has no effect) and an approved psoriasis treatment called apremilast, which is a pill taken twice a day. These medications were tested in adults with moderate to severe plaque psoriasis, which is psoriasis involving 10% or more of their body (equal to 10 or more handprints). The aims of the POETYK PSO-2 study were to find out if treatment with deucravacitinib could improve psoriasis for the participants in the study and to see if there were any side effects. Side effects are events that happened during treatment that may or may not be caused by that treatment. The study also wanted to find out what would happen after stopping treatment with deucravacitinib in participants who had shown major improvements in their psoriasis.

WHAT DO THE RESULTS OF THE POETYK PSO-2 STUDY SHOW?

After 4 months of treatment, more participants taking deucravacitinib had significantly greater improvements in psoriasis than those taking placebo or apremilast. The study also showed that participants continued to see these improvements after taking deucravacitinib for up to 1 year. Some participants maintained the improvements in their psoriasis with deucravacitinib after stopping treatment and switching to a placebo. Side effects for participants taking deucravacitinib were generally mild and occurred in similar numbers to those in participants taking placebo. The most common side effects in participants taking deucravacitinib were inflammation of the nose and throat (a common cold) which occurred at a similar rate in participants who took placebo. Clinical Trial Registration: NCT03611751 (POETYK PSO-2 study) (ClinicalTrials.gov).

Treatment of plaque psoriasis with deucravacitinib (POETYK PSO-1 study): a plain language summary

WHAT IS THIS SUMMARY ABOUT?

This is a summary of a paper published in a medical journal that describes the results of a study called POETYK PSO-1, which looked at a new treatment called deucravacitinib for plaque psoriasis. Plaque psoriasis appears on the body as round or oval raised patches (called plaques) typically covered by scales. This can cause the skin to itch, crack or bleed, and the associated itching and pain can make it difficult to perform basic everyday tasks. Living with psoriasis can cause emotional distress. Treatments are available, but some do not always reduce the symptoms of psoriasis, some may need to be injected or taken multiple times a day, and some may have side effects. Researchers are looking for new treatments that are more effective, convenient to take, and have acceptable safety and tolerability.

WHAT HAPPENED IN THE STUDY?

Deucravacitinib is a once-daily pill taken by mouth (orally) that was studied as a treatment for moderate to severe plaque psoriasis in adults in two large studies conducted globally, PSO-1 and PSO-2. The POETYK PSO-1 study compared deucravacitinib with placebo (an inactive pill designed to have no effect) and an approved psoriasis treatment called apremilast, which is a pill taken twice a day. These were tested in adults with moderate to severe plaque psoriasis, which involved 10% or more of their body (equal to 10 or more handprints). The aim of the study was to compare the ability of deucravacitinib with placebo or apremilast to improve psoriasis for the people in the study, and to compare side effects that people had.

WHAT DO THE RESULTS OF THE POETYK PSO-1 STUDY SHOW?

After 4 months of treatment, more people taking deucravacitinib had improvements in psoriasis plaques and skin appearance than those taking placebo or apremilast. The study also showed that people continued to see these improvements after taking deucravacitinib for up to 1 year. Side effects are events that happened during the study treatment phase that may or may not be caused by that treatment. Side effects for people taking deucravacitinib were generally mild and occurred in similar numbers overall to those in people taking placebo. The most common side effects in people taking deucravacitinib were inflammation or infection of the nasal (nose) passages and throat. Clinical Trial Registration: NCT03624127 (POETYK PSO-1 study) (ClinicalTrials.gov).

Deucravacitinib versus placebo and apremilast in moderate to severe plaque psoriasis: Efficacy and safety results from the 52-week, randomized, double-blinded, placebo-controlled phase 3 POETYK PSO-1 trial

BACKGROUND

Effective, well-tolerated oral psoriasis treatments are needed.

OBJECTIVE

To compare the efficacy and safety of deucravacitinib, an oral, selective, allosteric tyrosine kinase 2 inhibitor, versus placebo and apremilast in adults with moderate to severe plaque psoriasis.

METHODS

Participants were randomized 2:1:1 to deucravacitinib 6 mg every day (n = 332), placebo (n = 166), or apremilast 30 mg twice a day (n = 168) in the 52-week, double-blinded, phase 3 POETYK PSO-1 trial (NCT03624127). Coprimary end points included response rates for ≥75% reduction from baseline in Psoriasis Area and Severity Index (PASI 75) and static Physician's Global Assessment score of 0 or 1 (sPGA 0/1) with deucravacitinib versus placebo at week 16.

RESULTS

At week 16, response rates were significantly higher with deucravacitinib versus placebo or apremilast for PASI 75 (194 [58.4%] vs 21 [12.7%] vs 59 [35.1%]; P < .0001) and sPGA 0/1 (178 [53.6%] vs 12 [7.2%] vs 54 [32.1%]; P < .0001). Efficacy improved beyond week 16 and was maintained through week 52. Adverse event rates with deucravacitinib were similar to those with placebo and apremilast.

LIMITATIONS

One-year duration, limited racial diversity.

CONCLUSION

Deucravacitinib was superior to placebo and apremilast across multiple efficacy end points and was well tolerated in moderate to severe plaque psoriasis.

AB0890 Deucravacitinib, an Oral, Selective Tyrosine Kinase 2 Inhibitor, in Moderate to Severe Plaque Psoriasis: 52-Week Efficacy Results From the Phase 3 POETYK PSO-1 and POETYK PSO-2 Trials

Background

Tyrosine kinase 2 (TYK2) is an intracellular kinase that mediates signaling of key cytokines (eg, interleukin [IL]-23 and Type I interferons) involved in the pathogenesis of immune-mediated diseases including plaque psoriasis and psoriatic arthritis (PsA). Deucravacitinib is a novel, oral, selective, allosteric inhibitor of TYK2 that achieves high selectivity by uniquely binding to the regulatory domain of the enzyme, rather than to the more conserved active domain. Deucravacitinib showed superior efficacy compared with placebo at 16 weeks in a Phase 2 trial in patients with PsA (NCT03881059). Results from the 16-week, placebo-controlled periods of two 52-week, Phase 3 trials in psoriasis (POETYK PSO-1 and POETYK PSO-2) previously showed that deucravacitinib was significantly more efficacious than placebo and apremilast based on the coprimary endpoints of ≥75% reduction from baseline in Psoriasis Area and Severity Index (PASI 75) and a static Physician’s Global Assessment (sPGA) score of 0 or 1 (clear or almost clear) at Week 16.

Objectives

To evaluate the efficacy of deucravacitinib over 52 weeks in the POETYK PSO-1 and POETYK PSO-2 trials.

Methods

POETYK PSO-1 (NCT03624127) and PSO-2 (NCT03611751) were double-blinded trials that randomised patients with moderate to severe plaque psoriasis (body surface area involvement ≥10%, PASI ≥12, sPGA score ≥3) 2:1:1 to deucravacitinib 6 mg once daily, placebo, or apremilast 30 mg twice daily. Patients receiving placebo were switched to deucravacitinib at Week 16 in both trials. Patients randomised to deucravacitinib in PSO-1 received deucravacitinib continuously through Week 52. PSO-2 included a randomised withdrawal phase in which patients originally randomised to deucravacitinib who had achieved PASI 75 response at Week 24 were rerandomised 1:1 to placebo or deucravacitinib, whereas those who did not achieve PASI 75 response at Week 24 continued receiving deucravacitinib. The proportions of patients achieving PASI 75 and sPGA 0/1 responses were evaluated up to Week 52. Secondary efficacy endpoints evaluated over this period included PASI 90, PASI 100, percentage change from baseline in PASI, sPGA 0 (clear), change from baseline in the Psoriasis Symptoms and Signs Diary (PSSD) symptom score, and Dermatology Life Quality Index (DLQI) 0/1 (no impact on patient’s life).

Results

A total of 666 and 1020 patients were randomised in PSO-1 and PSO-2, respectively. Demographic and baseline disease characteristics were balanced across treatment groups; mean age was 46.6 years, mean disease duration was 18.6 years, 18.4% of patients had PsA, and 34.8% had previously used biologic therapy. PASI 75, PASI 90, and PASI 100 responses were maintained from Week 16 to Week 52 in PSO-1 (Figure 1). Additionally, sPGA responses were maintained during this period (sPGA 0/1: 53.6% to 52.7%; sPGA 0: 17.5% to 23.5%, respectively). Patients who switched from placebo to deucravacitinib at Week 16 demonstrated PASI 75 and sPGA 0/1 responses at Week 52 (68.3% and 53.8%, respectively) comparable to those observed in patients who received continuous deucravacitinib treatment from Day 1 (65.1% and 52.7%, respectively). In PSO-2, among deucravacitinib-treated patients who achieved PASI 75 at Week 24 and were rerandomised to continue treatment, responses were maintained at Week 52 in the majority of patients (PASI 75, 80.4% [119/148]; sPGA 0/1, 70.3% [83/118]). Results for percentage change from baseline in PASI, change from baseline in the PSSD symptom score, and DLQI 0/1 were consistent with those reported for PASI and sPGA responses.

Conclusion

Results from the Phase 3 POETYK PSO-1 and PSO-2 trials demonstrated that deucravacitinib was efficacious through 52 weeks in patients with moderate to severe plaque psoriasis. Clinical responses were maintained in patients who received continuous deucravacitinib treatment and were improved in patients who switched from placebo at Week 16 to deucravacitinib treatment.

POS1042 EFFICACY AND SAFETY OF DEUCRAVACITINIB, AN ORAL, SELECTIVE TYROSINE KINASE 2 (TYK2) INHIBITOR, COMPARED WITH PLACEBO AND APREMILAST IN MODERATE TO SEVERE PLAQUE PSORIASIS: RESULTS FROM THE PHASE 3 POETYK PSO-1 STUDY

Background:

Tyrosine kinase 2 (TYK2) is an intracellular kinase that mediates interleukin (IL)-23, IL-12, and interferon (IFN)α/β signaling. Deucravacitinib is a novel, oral, selective inhibitor of TYK2 acting via binding to the TYK2 regulatory domain.1 Phase 2 results showed deucravacitinib was efficacious and well tolerated versus placebo in patients with moderate to severe plaque psoriasis or active psoriatic arthritis.2,3 No herpes zoster infections, opportunistic infections, thromboembolic events, or hematologic or lipid abnormalities characteristic of Janus kinase (JAK) 1−3 inhibitors were reported in the Phase 2 trials.2,3

Objectives:

To compare the efficacy and safety of deucravacitinib versus placebo and apremilast in plaque psoriasis.

Methods:

This Phase 3, double-blinded, 52-week study (NCT03624127) randomized patients with moderate to severe plaque psoriasis (BSA ≥10%, PASI ≥12, sPGA ≥3) to deucravacitinib 6 mg once daily, placebo, or apremilast 30 mg twice daily (2:1:1). Patients receiving placebo were switched to deucravacitinib at Week 16; apremilast-treated patients not achieving PASI 50 at Week 24 were switched to deucravacitinib. Coprimary endpoints were PASI 75 and sPGA 0/1 response versus placebo at Week 16. Key secondary endpoints included superiority versus apremilast, assessed via multiple measures.

Results:

666 patients were randomized. Demographic and baseline disease characteristics were balanced across groups; mean age was 46.1 years, mean disease duration was 17.3 years, 18.2% of patients had psoriatic arthritis at baseline, and 38.9% had previously used biologic therapy. Mean BSA involvement at baseline was 26.3%, mean PASI was 21.4, and the percentage with severe sPGA (score=4) at baseline was 21.2%. Significantly greater proportions of patients in the deucravacitinib versus placebo and apremilast arms achieved PASI 75 (58.7% vs 12.7% vs 35.1%, respectively; P<0.0001) and sPGA 0/1 (53.6% vs 7.2% vs 32.1%, respectively; P<0.0001) response at Week 16 (Figure 1). Deucravacitinib was also superior to apremilast at Week 24, with 69.0% versus 38.1% of patients achieving PASI 75 and 58.4% versus 31.0% achieving sPGA 0/1 (P<0.0001 for both). In addition, DLQI 0/1 responses at Week 16 were significantly higher with deucravacitinib versus placebo and apremilast, demonstrating improved quality of life (40.7% vs 10.6% vs 28.6%, respectively; Figure 1). During the 16-week, placebo-controlled period, the most common AEs (≥5% in any arm) were nasopharyngitis, upper respiratory tract infection, headache, diarrhea, and nausea (Table 1). Frequencies of SAEs and treatment discontinuations due to AEs were low (Table 1).

Conclusion:

Deucravacitinib demonstrated superiority versus placebo and apremilast across multiple efficacy endpoints in patients with moderate to severe plaque psoriasis, and was generally well tolerated. Overall, the efficacy and safety profile of deucravacitinib was consistent with that observed in the Phase 2 plaque psoriasis and psoriatic arthritis trials.2,3

Immune checkpoint inhibition in sepsis: a Phase 1b randomized study to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of nivolumab

PURPOSE

Sepsis-associated immunosuppression increases hospital-acquired infection and viral reactivation risk. A key underlying mechanism is programmed cell death protein-1 (PD-1)-mediated T-cell function impairment. This is one of the first clinical safety and pharmacokinetics (PK) assessments of the anti-PD-1 antibody nivolumab and its effect on immune biomarkers in sepsis.

METHODS

Randomized, double-blind, parallel-group, Phase 1b study in 31 adults at 10 US hospital ICUs with sepsis diagnosed ≥ 24 h before study treatment, ≥ 1 organ dysfunction, and absolute lymphocyte count ≤ 1.1 × 10³ cells/μL. Participants received one nivolumab dose [480 mg (n = 15) or 960 mg (n = 16)]; follow-up was 90 days. Primary endpoints were safety and PK parameters.

RESULTS

Twelve deaths occurred [n = 6 per study arm; 40% (480 mg) and 37.5% (960 mg)]. Serious AEs occurred in eight participants [n = 1, 6.7% (480 mg); n = 7, 43.8% (960 mg)]. AEs considered by the investigator to be possibly drug-related and immune-mediated occurred in five participants [n = 2, 13.3% (480 mg); n = 3, 18.8% (960 mg)]. Mean ± SD terminal half-life was 14.7 ± 5.3 (480 mg) and 15.8 ± 7.9 (960 mg) days. All participants maintained > 90% receptor occupancy (RO) 28 days post-infusion. Median (Q1, Q3) mHLA-DR levels increased to 11,531 (6528, 19,495) and 11,449 (6225, 16,698) mAbs/cell in the 480- and 960-mg arms by day 14, respectively. Pro-inflammatory cytokine levels did not increase.

CONCLUSIONS

In this sepsis population, nivolumab administration did not result in unexpected safety findings or indicate any 'cytokine storm'. The PK profile maintained RO > 90% for ≥ 28 days. Further efficacy and safety studies are warranted. TRIAL REGISTRATION NUMBER (CLINICALTRIALS.GOV): NCT02960854.

An open-label, multiple ascending dose study of the anti-CTLA-4 antibody ipilimumab in viremic HIV patients

Expression of cytotoxic T-lymphocyte antigen 4 (CTLA-4), a negative regulator of T-cell function, is increased in chronic HIV-1 infection. It was hypothesized that CTLA-4 blockade may enhance immune response to HIV-1 and result in better control of viremia. This open-label, multiple ascending dose study (NCT03407105)-the first to examine ipilimumab in participants with HIV-1 infection-assessed the safety, tolerability, and pharmacokinetics of ipilimumab, as well as whether ipilimumab enhanced immune response to HIV-1 and improved control of viremia. Twenty-four participants received 2 or 4 doses of ipilimumab (0.1, 1, 3, or 5 mg/kg) every 28 days. No serious adverse events (AEs) or dose-limiting toxicities were reported; one participant discontinued ipilimumab for an AE of grade 2 facial palsy. Twenty participants (83.3%) had ≥1 AE; all but 1 were grade 1 or 2. Eight participants (33.3%) had potentially immune-related AEs (7 had grade 1 diarrhea not requiring corticosteroids; 1 who had diarrhea also had transient antinuclear antibody positivity; 1 had grade 2 facial palsy requiring corticosteroids). Two participants (8.3%), one each in the 0.1- and 1-mg/kg dose groups, had a decrease from baseline HIV-1 RNA of 0.85 and 1.36 log10 copies/mL. Fourteen participants (58.3%) had an increase from baseline HIV-1 RNA (mean, 0.87 log10 copies/mL; range, 0.59-1.29). Of these 14 participants, all but 1 were in the higher ipilimumab dose groups (3 or 5 mg/kg). No pattern was noted regarding change from baseline in CD4 or CD8 T cells; ex vivo assessments of immune response were precluded because of inadequate cell viability. Serum concentration data for ipilimumab showed biphasic disposition, with steady state reached by dose 3. Ipilimumab treatment was well tolerated and was associated with variations in HIV-1 RNA in excess of expected repeat measures in most participants, but these were not related to combination antiretroviral therapy status or CD4 counts. The mechanism(s) underlying the increased variation in HIV-1 RNA is unclear and needs further study.

Discovery of a Hepatitis C Virus NS5B Replicase Palm Site Allosteric Inhibitor (BMS-929075) Advanced to Phase 1 Clinical Studies

The hepatitis C virus (HCV) NS5B replicase is a prime target for the development of direct-acting antiviral drugs for the treatment of chronic HCV infection. Inspired by the overlay of bound structures of three structurally distinct NS5B palm site allosteric inhibitors, the high-throughput screening hit anthranilic acid 4, the known benzofuran analogue 5, and the benzothiadiazine derivative 6, an optimization process utilizing the simple benzofuran template 7 as a starting point for a fragment growing approach was pursued. A delicate balance of molecular properties achieved via disciplined lipophilicity changes was essential to achieve both high affinity binding and a stringent targeted absorption, distribution, metabolism, and excretion profile. These efforts led to the discovery of BMS-929075 (37), which maintained ligand efficiency relative to early leads, demonstrated efficacy in a triple combination regimen in HCV replicon cells, and exhibited consistently high oral bioavailability and pharmacokinetic parameters across preclinical animal species. The human PK properties from the Phase I clinical studies of 37 were better than anticipated and suggest promising potential for QD administration.

The pharmacokinetics of peginterferon lambda-1a following single dose administration to subjects with impaired renal function

AIMS

This open label study was conducted to assess the effect of renal impairment (RI) on the pharmacokinetics (PK) of peginterferon lambda-1a (Lambda).

METHODS

Subjects (age 18-75 years, BMI 18-35 kg m(-2) ) were enrolled into one of five renal function groups: normal (n = 12), mild RI (n = 8), moderate RI (n = 8), severe RI (n = 7), end-stage renal disease (ESRD, n = 8) based on estimated glomerular filtration rate (eGFR) calculated using the Modification of Diet in Renal Disease (MDRD) equation. Subjects received a single dose of Lambda (180 µg) subcutaneously on day 1 followed by PK serum sample collections through day 29. Safety, tolerability and immunogenicity data were collected through day 43. PK parameters were estimated and summarized by group. Geometric mean ratios (GMR) and 90% confidence intervals (CIs) were calculated between normal and RI groups.

RESULTS

With decreasing eGFR, Lambda exposure (Cmax , AUC) increased while apparent clearance (CL/F) and apparent volume of distribution (V/F) decreased. Relative to subjects with normal renal function (geometric mean AUC = 99.5 ng ml(-1) h), Lambda exposure estimates (AUC) were slightly increased in the mild RI group (geometric mean [90% CI]: 1.20 [0.82, 1.77]) and greater in the moderate (1.95 [1.35, 2.83]), severe RI (1.95 [1.30, 2.93]) and ESRD (1.88 [1.30, 2.73]) groups. Lambda was generally well tolerated.

CONCLUSIONS

The results demonstrated that RI reduces the clearance of Lambda and suggests that dose modifications may not be required in patients with mild RI but may be required in patients with moderate to severe RI or ESRD.

Soluble receptor-resistant poliovirus mutants identify surface and internal capsid residues that control interaction with the cell receptor

Poliovirus initiates infection by binding to its cell receptor and undergoing a receptor-mediated conformational alteration. To identify capsid residues that control these interactions, we have isolated and characterized poliovirus mutants that are resistant to neutralization by a soluble form of the poliovirus receptor. Twenty one soluble receptor-resistant (srr) mutants were identified which still use the poliovirus receptor to infect cells. All but one srr mutant contain a single amino acid change at one of 13 different positions, either on the surface or in the interior of the virion. The results of binding and alteration assays demonstrate that both surface and internal capsid residues regulate attachment to the receptor and conformational change of the virus. Mutations that reduce alteration also affect receptor binding, suggesting a common structural basis for early events in poliovirus infection.
