A Phase 2, Multicenter, Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Study to Assess the Impact of Intravenous RSLV-132 in Participants with Primary Sjögren's Syndrome (pSS) with Moderate to Severe Symptom Burden

The goal of this clinical study is to learn if RSLV-132 improves the symptoms of pSS in adults. It will also learn about the safety of RSLV-132. The main questions it aims to answer are:
* Does RSLV-132 improve the cardinal symptoms of Sjogren's including fatigue, dryness and pain?
* Does RSLV-132 improve the tiredness/fatigue caused by Sjogren's?
* What are the blood levels of RSLV-132 over time?
* What is the immune (antibody) response in the body to RSLV-132?
* What is the safety profile of RSLV-132?
Researchers will compare RSLV-132 to a placebo (a look-alike substance that contains no drug) to see if RSLV-132 improves the symptoms of pSS.
Participants will:
Take RSLV-132 or a placebo 13 times over 22 weeks Visit the clinic once every week for the first 2 weeks, then every 2 weeks until the end of treatment and then for a final time 4 weeks later (Day 211) for check-ups, tests and to answer questionnaires about their symptoms Record their symptoms every day on an electronic device

Evaluation of RNase therapy in systemic lupus erythematosus: a randomised phase 2a clinical trial of RSLV-132

Article

Author: Posada, James ; Werth, Victoria P ; Boackle, Susan A ; Burge, Daniel J

Background:

Circulating, extracellular RNA is the primary trigger of type I interferon in systemic lupus erythematosus (SLE), and interferon is known to play a central pathogenic role in the disease. RSLV-132 is a catalytically active human RNase molecule fused to human IgG1 Fc designed to digest RNA and thereby decrease the chronic inflammation associated with SLE. The drug was evaluated in a cohort of patients with SLE with moderate-severe cutaneous disease activity and the presence of RNA immune complexes. The primary objective of the study was the assessment of the impact of 13 doses of 10 mg/kg RSLV-132 over 6 months on the mean Cutaneous Lupus Erythematosus Disease Area and Severity Index (CLASI) score.

Methods:

Sixty-five patients meeting the entry criteria of a baseline CLASI score of 10 or greater and positivity of at least one of five autoantibodies to RNA-binding proteins (SM/RNP, SSA/Ro, SSB/La, Sm, RNP) were randomly assigned (2:1) to receive 13 doses of RSLV-132 10 mg/kg or placebo, respectively. Participants received study drug for 24 weeks on days 1, 8, 15, 29, 43, 57, 71, 85, 99, 113, 127, 141 and 155 with an end-of-treatment visit on day 169 and a follow-up visit at the end of the study on day 215. The primary objective was assessed on days 85 and 169. Secondary objectives included assessment of systemic disease activity using the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K), the British Isles Lupus Assessment Group 2004 Index and the Physician’s Global Assessment. Data from these instruments were used to calculate the SLE Responder Index 4 (SRI-4) and the British Isles Lupus Assessment Group-based Composite Lupus Assessment (BICLA) scores.

Results:

The mean CLASI score change from baseline at day 169 was −5.7 (±7.0) in the placebo group and −6.2 (±8.5) in the RSLV-132 group. A subgroup of participants with moderate-severe systemic disease activity and high baseline SLEDAI scores (≥9) were analysed with respect to BICLA and SRI-4 responses. The RSLV-132 treated participants in the high SLEDAI subgroup had a greater percentage of BICLA responses (62% vs 44%) and SRI-4 responses (23% vs 11%) as compared with placebo. A second subgroup of participants with high baseline CLASI scores (≥21) were analysed with respect to BICLA and SRI-4 responses. The RSLV-132 treated participants in the high CLASI subgroup had a greater percentage of BICLA responses (28% vs 8%) and SRI-4 responses (39% vs 8%) as compared with placebo.

Conclusions:

Six months of RSLV-132 therapy consisting of a weekly loading dose of RSLV-132 for 1 month, followed by 5 months of biweekly administrations did not significantly improve the mean CLASI score relative to placebo in this cohort of patients with SLE. The study entry criteria selected patients with moderate-severe cutaneous disease activity and no minimum SLEDAI score, which resulted in a wide range of systemic disease activity from inactive to severe as measured by SLEDAI. When the participants with higher SLEDAI and CLASI scores were analysed, a trend towards clinical improvement favouring RSLV-132 was observed. The results warrant further evaluation of RSLV-132 in SLE and suggest that patients with more active systemic disease are most likely to benefit from RNase therapy.

Improvement of Severe Fatigue Following Nuclease Therapy in Patients With Primary Sjögren’s Syndrome: A Randomized Clinical Trial

Q1 · MEDICINE

Article

Author: Valadkhan, Saba ; Barone, Francesca ; Posada, James ; Gallagher, Peter ; Davies, Kristen ; Wilson, Douglas ; Ng, Wan‐Fai ; Burge, Daniel ; Fisher, Benjamin A. ; Jobling, Kerry ; Tarn, Jessica ; Casement, John

Objective:

To assess the safety and efficacy of RSLV‐132, an RNase Fc fusion protein, in a phase II randomized, double‐blind, placebo‐controlled clinical trial in patients with primary Sjögren’s syndrome (SS).

Methods:

Thirty patients with primary SS were randomized to receive treatment with RSLV‐132 or placebo intravenously once per week for 2 weeks, and then every 2 weeks for 12 weeks. Eight patients received placebo and 20 patients received RSLV‐132 at a dose of 10 mg/kg. Clinical efficacy measures included the European League Against Rheumatism (EULAR) Sjögren’s Syndrome Disease Activity Index, EULAR Sjögren’s Syndrome Patient Reported Index (ESSPRI), Functional Assessment of Chronic Illness Therapy–Fatigue (FACIT‐F), Profile of Fatigue (ProF), and the Digit Symbol Substitution Test (DSST).

Results:

Patients randomized to receive RSLV‐132 experienced clinically meaningful improvements in the ESSPRI score (P = 0.27), FACIT‐F score (P = 0.05), ProF score (P = 0.07), and DSST (P = 0.02) from baseline to day 99, whereas patients who received placebo showed no changes in any of these clinical efficacy measures. This improvement was significantly correlated with increased expression of selected interferon‐inducible genes (Pearson’s correlations, each P < 0.05).

Conclusion:

Administration of RSLV‐132 improved severe fatigue, as determined by 4 independent patient‐reported measures of fatigue, in patients with primary SS.

Author: Burge, D J ; Sherrer, Y ; Eisenman, J ; Byrnes-Blake, K ; Posada, J A ; Cohen, S B ; Lau, K ; Levin, R ; Kivitz, A J ; Martin, R W ; Smolak, P

Blood-borne RNA circulating in association with autoantibodies is a potent stimulator of interferon production and immune system activation. RSLV-132 is a novel fully human biologic Fc fusion protein that is comprised of human RNase fused to the Fc domain of human IgG1. The drug is designed to remain in circulation and digest extracellular RNA with the aim of preventing activation of the immune system via Toll-like receptors and the interferon pathway. The present study describes the first clinical study of nuclease therapy in 32 subjects with systemic lupus erythematosus. The drug was well tolerated with a very favorable safety profile. The approximately 19-day serum half-life potentially supports once monthly dosing. There were no subjects in the study that developed anti-RSLV-132 antibodies. Decreases in B-cell activating factor correlated with decreases in disease activity in a subset of patients.

Resolve Therapeutics Publishes Results of RSLV-132 Phase 2 Long COVID Study

MIAMI, May 13, 2024 /PRNewswire/ -- Resolve Therapeutics, a mid-stage clinical development company pioneering transformative therapies for autoimmune and post-viral illnesses, today announced the publication of its phase 2 long COVID results in Clinical Infectious Diseases. The publication entitled "Assessment of the Impact of RNase in Patients with Severe Fatigue Related to Post-Acute Sequelae of SARS-CoV-2 Infection (PASC): A randomized phase 2 trial of RSLV-132" evaluated the impact of RNase in one hundred and eight patients diagnosed with COVID-19 at least 6 months prior to baseline and with a history of continuous, severe fatigue. Participants received 6 doses of RSLV-132 or placebo over two months. The study measured fatigue and overall disease activity using the PROMIS SF 10a, FACIT-Fatigue, and physician's global assessment. Approximately 18 million Americans suffer the debilitating effects of long COVID. The most common symptoms are extreme fatigue, brain fog, immune dysregulation and depression or anxiety. Despite the large unmet medical need, A recent editorial in The Lancet identified only 12 pharmacological interventional clinical trials in development. Thus, very little progress has been made towards identifying drugs to treat the cardinal symptoms of long COVID. RSLV-132 has demonstrated significant clinical activity in improving autoimmune-related fatigue in Sjogren's syndrome. Results from the current long COVID phase 2 study suggest patients suffering from long COVID may also benefit from the removal of circulating RNA. "We are encouraged by the potential for RSLV-132 to improve the debilitating fatigue suffered by so many long COVID patients" commented Dr. James Posada chief executive officer of Resolve Therapeutics. "Interestingly, our data further suggests that women may respond better to RSLV-132 and digestion of latent viral RNA than men" added Dr. Posada. About RSLV-132 RSLV-132 is a non-immunosuppressive, biologic drug comprised of catalytically active human RNase1 fused to the Fc region of human IgG1. It is designed to remain in serum circulation and digest extracellular pathogenic RNA. RNA is the primary trigger of interferon and cytokine production that drives chronic inflammation in diseases such as SLE, Sjogren's. Recent studies suggest that RNA may play a role in post-viral illnesses such as PASC and ME/CFS as well. Therefore, removing it from circulation may decrease inflammation and improve the symptoms associated with these diseases. About Resolve Therapeutics Resolve is a private biotech company pioneering a transformative approach to autoimmune and post-viral diseases. The company is leveraging the extensive body of scientific discoveries that demonstrate the central role of pathogenic RNA molecules, weather self-derived or from viral sources, in driving inflammatory and neuroinflammatory symptoms. Resolve is actively developing RSLV-132 in mid-stage clinical development programs including SLE, Sjogren's syndrome, and post-acute sequelae of SARS-CoV-2 infection (PASC).
