Avatrombopag for the treatment of thrombocytopenia induced by chemotherapy in patients with solid tumors: A multicenter, open-label, single-arm trial.

ABSTRACT: Objective: To explore the effect and safety of avatrombopag for chemotherapy-induced thrombocytopenia (CIT). Methods: This multicenter, open-label, single-arm trial enrolled CIT patients in eight centers from October 2020 to April 2021. The participants received avatrombopag tablets 60 mg once a day for 5-10 days. The main endpoint was the proportion of patients with platelet count ≥100×10⁹/L or increased by ≥ 50×10⁹/L or increased by ≥ 100% in the cycle after the start of treatment. Results: Seventy-four participants were enrolled with a mean age of 59.8 ± 11.62.2% were males. The cumulative effective rate (any criteria) was 70.3% at 4 weeks. 42 (56.8%) achieved platelet count ≥100×10⁹/L, 44 (59.5%) increased by ≥ 50×10⁹/L, and 27 (36.5%) increase by ≥ 100% from baseline. The duration of grade III and IV platelet reduction was 4.2 ± 5.3 days. The time of PLT recovery to ≥75×10⁹/L was 9.4 ± 6.6 days. The time of PLT recovery to ≥100×10⁹/L was 10.2 ± 6.4 days. The platelet count nadir was 57.9 ± 45.3×10⁹/L. The most common adverse events were nausea (8.1%), fatigue (5.4%), and abdominal pain (1.4%). There were no cases of fever, headache, or peripheral edema. Conclusion: Although it was a single-arm trial without a control group, the application of avatrombopag in patients with CIT can increase the platelet count of the patients compared with baseline. Avatrombopag is safe and tolerable. Clinical Trial Registration: https://clinicaltrials.gov/ct2/show/NCT04609891?term=04609891&draw=2&rank=1, identifier [NCT04609891].

Project description:BackgroundFGFR genomic aberrations occur in approximately 5-10% of human cancers. Erdafitinib has previously demonstrated efficacy and safety in FGFR-altered advanced solid tumors, such as gliomas, thoracic, gastrointestinal, gynecological, and other rare cancers. However, its efficacy and safety in Asian patients remain largely unknown. We conducted a multicenter, open-label, single-arm phase IIa study of erdafitinib to evaluate its efficacy in Asian patients with FGFR-altered advanced cholangiocarcinoma, non-small cell lung cancer (NSCLC), and esophageal cancer.MethodsPatients with pathologically/cytologically confirmed, advanced, or refractory tumors who met molecular and study eligibility criteria received oral erdafitinib 8 mg once daily with an option for pharmacodynamically guided up-titration to 9 mg on a 28-day cycle, except for four NSCLC patients who received erdafitinib 10 mg (7 days on/7 days off) as they were recruited before the protocol amendment. The primary endpoint was investigator-assessed objective response rate per RECIST v1.1. Secondary endpoints included progression-free survival, duration of response, disease control rate, overall survival, safety, and pharmacokinetics.ResultsThirty-five patients (cholangiocarcinoma: 22; NSCLC: 12; esophageal cancer: 1) were enrolled. At data cutoff (November 19, 2021), the objective response rate for patients with cholangiocarcinoma was 40.9% (95% CI, 20.7-63.6); the median progression-free survival was 5.6 months (95% CI, 3.6-12.7) and median overall survival was 40.2 months (95% CI, 12.4-not estimable). No patient with RET/FGFR-altered NSCLC achieved objective response and the disease control rate was 25.0% (95% CI, 5.5-57.2%), with three patients with stable disease. The single patient with esophageal cancer achieved partial response. All patients experienced treatment-emergent adverse events, and grade ≥ 3 treatment-emergent adverse events were reported in 22 (62.9%) patients. Hyperphosphatemia was the most frequently reported treatment-emergent adverse event (all-grade, 85.7%).ConclusionsErdafitinib demonstrated efficacy in a population of Asian patients in selected advanced solid tumors, particularly in those with advanced FGFR-altered cholangiocarcinoma. Treatment was tolerable with no new safety signals.Trial registrationThis trial is registered with ClinicalTrials.gov (NCT02699606); study registration (first posted): 04/03/2016.

Project description:Objective To evaluate the efficacy and tolerability of single pulse transcranial magnetic stimulation (sTMS) for the preventive treatment of migraine. Background sTMS was originally developed for the acute treatment of migraine with aura. Open label experience has suggested a preventive benefit. The objective of this trial was to evaluate the efficacy and tolerability of sTMS for migraine prevention. Methods The eNeura SpringTMS Post-Market Observational U.S. Study of Migraine (ESPOUSE) Study was a multicenter, prospective, open label, observational study. From December 2014 to March 2016, patients with migraine (n = 263) were consented to complete a 1-month baseline headache diary followed by 3 months of treatment. The treatment protocol consisted of preventive (four pulses twice daily) and acute (three pulses repeated up to three times for each attack) treatment. Patients reported daily headache status, medication use, and device use with a monthly headache diary. The primary endpoint, mean reduction of headache days compared to baseline, was measured over the 28-day period during weeks 9 to 12. The primary endpoint was compared to a statistically-derived placebo estimate (performance goal). Secondary endpoints included: 50% responder rate, acute headache medication consumption, HIT-6, and mean reduction in total headache days from baseline of any intensity. Results Of a total of 263 consented subjects, 229 completed a baseline diary, and 220 were found to be eligible based on the number of headache days. The device was assigned to 217 subjects (Safety Data Set) and 132 were included in the intention to treat Full Analysis Set. For the primary endpoint, there was a -2.75 ± 0.40 mean reduction of headache days from baseline (9.06 days) compared to the performance goal (-0.63 days) ( p < 0.0001). The 50% responder rate of 46% (95% CI 37%, 56%) was also significantly higher ( p < 0.0001) than the performance goal (20%). There was a reduction of -2.93 (5.24) days of acute medication use, headache impact measured by HIT-6, -3.1 (6.4) ( p < 0.0001), and total headache days of any intensity -3.16 days (5.21) compared to the performance goal (-0.63 days) ( p < 0.0001). The most common adverse events were lightheadedness (3.7%), tingling (3.2%), and tinnitus (3.2%). There were no serious adverse events. Conclusions This open label study suggests that sTMS may be an effective, well-tolerated treatment option for migraine prevention. Trial registration number NCT02357381.

Project description:IntroductionCervical disc herniation (CDH) is the most common cause of cervical radiculopathy and causes persistent neck pain and neurological deficits. Collagenase chemonucleolysis has been successfully applied to treat lumbar disc herniation, which has a similar pathological mechanism to CDH. However, its application for CDH remains under-researched, and there is an even greater lack of high-quality clinical evidence. This study aims to evaluate the efficacy and safety of collagenase chemonucleolysis for treating CDH.MethodsEligible patients with CDH underwent collagenase chemonucleolysis via anterior cervical intradiscal injection or epidural injection. The primary efficacy endpoint showed an excellent and good rate regarding the Odom criteria, which was not lower than the reference value (≥ 78%) at 6 months postoperatively. The secondary efficacy endpoints were the percentage reduction in Numeric Rating Scale (NRS) and Neck Disability Index (NDI) scores from baseline, which were not lower than the reference values (≥ 40%, ≥ 30%), and improvement in the 36-Item Short Form Health Survey (SF-36) score compared to the preoperative value. The pre- and postoperative CDH index of patients were also compared. Safety endpoints included the incidence of adverse events (AEs) and serious adverse events (SAEs).ResultsAn excellent and good rate regarding the Odom criteria 6 months postoperatively was 90.5% (133/147), which was significantly higher than 78% (P < 0.004, 95% confidence interval 85.7-95.2%). The reduction in NRS and NDI scores exceeded 40% (P < 0.001) and 30% (P < 0.001), respectively. The SF-36 scores at 3 months and 6 months postoperatively were significantly higher than those preoperatively (P < 0.001). A significant difference was observed in the pre- and postoperative CDH index (109.6 ± 119.1 vs. 70.8 ± 74.8, P < 0.001). The incidence of AEs was 22.5% (33/147), of which 97.8% were grade 1-2. No collagenase-related AEs and SAEs occurred.ConclusionCollagenase chemonucleolysis treatment for CDH exhibited favorable efficacy and safety and may be a better choice for patients in whom conservative treatment is ineffective.Trial registrationThe trial was registered on www.Chictr.org.cn (ChiCTR2200063043).

Project description:BackgroundNeoadjuvant therapy has significantly improved the 5-year overall survival (OS) of patients with resectable non-small cell lung cancer (NSCLC). The CheckMate 159 trial showed that neoadjuvant therapy with a single-drug programmed cell death protein 1 (PD-1) inhibitor (nivolumab) achieved major pathological response (MPR) and pathological complete response (pCR) in 45% and 15%of participants, respectively. We conducted an open-label single-arm study to evaluate the safety and efficacy of neoadjuvant PD-1 inhibitors in combination with chemotherapy in the treatment of resectable NSCLC.MethodsThis study was conducted in a total of 2 hospitals in the Chinese cities of Xi'an and Chongqing, and included eligible patients over 18 years of age with clinically staged IIA-IIIB NSCLC. All patients were scheduled to receive surgery within 4-6 weeks after neoadjuvant treatment (3-4 cycles) consisting of PD-1 inhibitors combined with a conventional chemotherapy regimen on day 1 of each 21-day cycle.ResultsTwenty-three patients, 22 males, and 1 female with just one of them with no smoking habits) were diagnosed with NSCL C in a stage IIA (3 cases), IIB (3 cases), IIIA (8 cases), and IIIB (9cases) and no druggable driver mutations/translocations were addressed to receive neoadjuvant treatment between June 2018 and June 2020. The treatment was well tolerated with just 3 typical immune-related adverse events (hyperthyroidism, hyperglycemia, and rash) recorded. There was a partial response (PR) and stable disease (SD) in 17 (73.9%) and 6 (26.1%) patients, with an overall response rate (ORR) of 73.9% according to the Response Evaluation Criteria in Solid Tumors (RECIST v.1.1). Six of these patients resulted in pCR (30%) while ten of them showed a MPR (50%). Twenty patients underwent surgical resection after treatment, while further 3 refused surgery. Surgical procedure included video-assisted thoracoscopic resection (10 cases), Vinci Robot surgery (4 cases), and thoracotomy in 4 cases while there were secondary compliance-related thoracotomy in two cases. The pathology analysis revealed a R0 in 19 cases (19/20, 95%).ConclusionsOur results suggest that the neoadjuvant approach with chemotherapy and PD-1 blocking mAbs is safe and active in patients with resectable NSCLC where is associated with a promising high ORR, MPR and pCR.
