Burden of systemic lupus erythematosus in clinical practice: baseline data from the SLE Prospective Observational Cohort Study (SPOCS) by interferon gene signature.

OBJECTIVE: The longitudinal Systemic Lupus Erythematosus Prospective Observational Cohort Study (SPOCS) aims to assess SLE disease course overall and according to type I interferon 4 gene signature (IFNGS). Here, we describe SPOCS patient characteristics by IFNGS and baseline disease activity. METHODS: SPOCS (NCT03189875) is an international study of patients with SLE according to Systemic Lupus International Collaborating Clinics (SLICC)/American College of Rheumatology (ACR) criteria. Enrolled patients from 135 centres in 8 countries were followed biannually for ≤3 years from June 2017 to November 2022. Baseline demographics, disease characteristics, organ system involvement/damage and flares were analysed descriptively according to SLE Disease Activity Index-2000 score (SLEDAI-2K <10/≥10) and IFNGS status (high/low). RESULTS: The study population (n=823) was 93.2% female, with mean (SD) age 45.3 (13.9) years and 11.1 (9.2) years since diagnosis; 52.4% had baseline SLICC/ACR Damage Index score ≥1. Patients with SLEDAI-2K scores ≥10 (241 of 584, 41.3%) vs <10 were younger (mean 42.8 (13.7) vs 46.6 (14.2) years; nominal p=0.001), had shorter SLE duration (10.4 (8.6) vs 12.4 (9.6) years; nominal p=0.012) and more severe flares (12.9% vs 5.3%; nominal p=0.001). IFNGS-high patients (522 of 739, 70.6%) were younger than IFNGS-low patients at first SLE manifestation (30.0 (12.7) vs 36.8 (14.6) years; nominal p<0.001). Proportions of IFNGS-high patients differed according to race (nominal p<0.001), with higher proportions among Asian (83.3%) and black (86.5%) versus white patients (63.5%). Greater proportions of IFNGS-high versus IFNGS-low patients had haematological (12.6% vs 4.1%), immunological (74.4% vs 45.6%) or dermal (69.7% vs 62.2%) involvement. CONCLUSIONS: We identified key characteristics of patients with high disease activity and/or elevated type I IFN signalling, populations with SLE with high unmet needs. Baseline SLEDAI-2K ≥10 was associated with shorter disease duration and more severe flares. IFNGS-high patients were younger at diagnosis and had distinct patterns of organ involvement, compared with IFNGS-low patients.

Conceptual assessment of HRQOL among Japanese non-metastatic castration-resistant prostate cancer (nmCRPC) patients.

OBJECTIVE: The study objectives were to understand how patients view the quality of life in non-metastatic castration-resistant prostate cancer (nmCRPC), including unmet needs and what patients consider most important in treatment outcomes. A gap analysis was conducted on existing patient-reported outcomes (PROs) measures versus what is missing from the patient perspective, to guide future development of PRO-based real-world evidence for nmCRPC in Japan. A conceptual model for nmCRPC Japanese patients' HRQOL was also created. METHODS: This non-interventional, qualitative study consisted of a targeted literature review, PRO instrument review, and interviews with 20 nmCRPC patients and five treating physicians. Triangulation of the gap analysis, evidence from the targeted review of the literature, and qualitative interview findings were employed to assess the comprehensiveness of current nmCRPC and HRQOL measures. RESULTS: Symptoms most reported by patients were frequent urination (70%), nocturia (65%), and general pain (65%). Others reported included lack of strength (30%). HRQOL impacts most reported were anxiety (45%) and worry (50%) about their diagnosis. Additional impacts mentioned were weight changes, loss of sleep, difficulty walking, loss of appetite, and difficulty traveling and seeking toilets in public. The gap analysis revealed 31 symptoms and 33 impacts not covered in existing prostate cancer-specific PRO instruments. Patients mentioned musculoskeletal symptoms such as fractures, leg pain, cramps, numbness, and loss of leg bone strength. Impacts not previously discussed in the literature or in outcome measures were feelings of self-consciousness around diagnosis, stigma around illness, and the impact on mobility including traveling. CONCLUSION: Key results reveal pain and urinary symptoms are the most experienced by Japanese nmCRPC patients. The diagnosis and treatment of disease leads to significant impacts in patient lives. Analysis revealed that symptoms and life impacts are missing in the current literature and outcome measures. Testing and debriefing of specific items could further substantiate these dimensions.

A qualitative study to understand the experience of somatostatin analog treatments from the perspective of patients with neuroendocrine tumors.

PURPOSE: Neuroendocrine tumors (NETs) negatively impact patients' quality of life. Octreotide long-acting release (LAR) and lanreotide depot are somatostatin analogs (SSAs) approved to treat NETs. The study objective was to explore SSA treatment experiences and preferences of patients with NETs. METHODS: Qualitative interviews were conducted in US adults (≥ 21 years) with NETs who had ≥ 6 months' treatment with each SSA and transitioned from octreotide LAR to lanreotide depot within the previous year. Participants were asked open-ended questions about their experiences with octreotide LAR and lanreotide depot, treatment preferences, and SSA treatment attributes. RESULTS: Twenty participants (mean age: 58 years; 90% female; 85% white) completed interviews. The most common reasons for treatment transition were doctor recommendation (70%), treatment not working as expected (55%), and injection type preference (45%). Participants reported 34 unique favorable attributes of SSA treatment and 82 unique unfavorable attributes. Symptom control was the most frequently reported favorable attribute (associated with octreotide LAR by 60% of participants and lanreotide depot by 65%). Painful injection (65%) was most frequently cited unfavorable attribute for octreotide LAR and injection experience dependent on administrator (35%) for lanreotide depot. The three SSA treatment attributes rated as most important were side effects, symptom control, and ability to stabilize tumor. CONCLUSION: Our qualitative data provide valuable insight into the treatment attributes that patients with NETs consider important when making SSA treatment decisions. Factors related to injection administration, side effects, and symptom control are important to patients and should be included in patient-provider communications in clinical contexts.

Development and Validation of a Visual Symptom-Specific Patient-Reported Outcomes Instrument for Adults With Cataract Intraocular Lens Implants.

PURPOSE: To develop a patient-reported outcome measure for capturing visual and ocular symptoms before and after implantation of intraocular lenses (IOLs) for treatment of cataracts. DESIGN: Questionnaire development and validation study. METHODS: The Questionnaire for Visual Disturbances (QUVID) was developed based on a literature and instrument review; 13 clinician interviews among ophthalmologists in the United States and Europe; and 67 hybrid qualitative patient interviews among adult patients in the United States and Australia before and/or after monofocal, traditional multifocal, or trifocal IOL implantation. Assessment of the QUVID's psychometric properties was conducted via a noninterventional cross-sectional study of previously treated cataract patients in the United States, Canada, and Australia (n = 150), and assessment of ability to detect meaningful change via 2 pivotal US clinical trials among patients with trifocal or extended vision IOL compared with monofocal IOL controls (n = 457). RESULTS: The QUVID includes subitems about the bothersomeness of 7 visual symptoms: starburst, halo, glare, hazy vision, blurred vision, double vision, and dark areas. The postoperative version contains 1 item asking the respondents whether their symptoms bothered them enough to want another surgery, if the IOL was the cause. CONCLUSIONS: The QUVID was reviewed by the US Food and Drug Administration and found appropriate as a fit-for-purpose measure, demonstrating requisite evidence for content validity, construct validity, reliability, and ability to detect change.

Development of the Multiple Myeloma Symptom and Impact Questionnaire: A New Patient-Reported Outcome Instrument to Assess Symptom and Impacts in Patients With Multiple Myeloma.

OBJECTIVES: This study aimed to develop and assess the content validity of a patient-reported outcomes (PROs) instrument to measure symptoms and impacts experienced by patients with active multiple myeloma (MM). METHODS: The PRO instrument was developed using an iterative, mixed-methods approach. The list of concepts was generated based on a review of existing evidence (qualitative studies and literature) and post hoc psychometric evaluations of 2 PRO instruments in 3 clinical trials. A total of 30 adult patients with MM from the United States participated in hybrid concept elicitation/cognitive debriefing interviews to validate the content validity of the newly developed PRO instrument. Translatability assessment was completed in 8 languages. RESULTS: The item generation process resulted in 17 symptom and 9 impact concepts for evaluation. The concept elicitation interviews and analysis were based on the first 25 participants; evidence of saturation was observed. The cognitive debriefing interviews and analysis were based on the last 23 participants across 4 waves of interviews. On the basis patient feedback, 10 items were removed, and 1 item was added to the PRO instrument. The translatability assessment resulted in 1 minor revision. The multiple myeloma symptom and impact questionnaire (MySIm-Q) includes 11 symptom and 6 impact concepts, organized within 8 hypothesized subdomains, with each concept measured using a 5-point verbal rating scale and a 7-day recall period. CONCLUSIONS: The MySIm-Q instrument was developed using rigorous and mixed methodology and with direct input from patients who received a diagnosis of MM. The MySIm-Q has good content validity and is culturally relevant for use in global clinical trials.

A qualitative research study in Japan investigating patients' experience with metastatic castration-resistant prostate cancer: from diagnosis to decision for Ra-223 treatment.

Aim: This qualitative study aimed to reveal symptoms and impacts among bone metastatic castration-resistant prostate cancer (or mCRPC) Japanese patients, prior to Radium-223 (Ra-223) treatment. Materials & Methods: Twenty-three mCRPC patients designated to receive Ra-223 and three treating physicians (Ra-223 prescribers) in Japan, were interviewed. All interview data were assessed for concept frequency, themes and saturation. Results: Forty-five percent of the patients (mean age: 75.8 years) were symptomatic at the time of enrollment. Interviews with all patients revealed 47 mCRPC symptoms, including back pain and bone-specific pain, and 45 life impacts, including worry about disease progression and the impact on daily, physical activities. Conclusion: The symptoms and impacts of living with mCRPC and the associated burden of bone metastasis and skeletal-related symptoms are varied and are important considerations for treatment.

Lay abstract Aim: This study looked at symptoms and impacts among patients with a type of prostate cancer called metastatic castration-resistant prostate cancer. This cancer has spread to other parts of the body including patients' bones. Patients' prostate-specific antigen levels continue to rise despite surgical or medical treatment and their doctors decided the next best treatment is Radium-223 (Ra-223), a radiopharmaceutical therapy. Materials & methods: Twenty-three metastatic castration-resistant prostate cancer patients designated to receive Ra-223 and three treating physicians (Ra-223 prescribers) in Japan, were interviewed. All interview data were assessed for the number of times some words or themes are mentioned by the patients. Results: Ten of the 23 patients (average age of 76 years) had symptoms when the study started. Interviewed patients talked about symptoms including back pain and pain in their bones, and how their cancer caused them to worry about their physical activities and disease progression. Conclusion: The symptoms impact on patients' daily living and the burden of bone metastasis and bone-related symptoms are varied and are important considerations for treatment.
