Biophysical effects and neuromodulatory dose of transcranial ultrasonic stimulation

Article

作者: Verhagen, Lennart ; Stagg, Charlotte J ; Naftchi-Ardebili, Kasra ; Nandi, Tulika ; Kop, Benjamin R ; Pauly, Kim Butts

Transcranial ultrasonic stimulation (TUS) has the potential to usher in a new era for human neuroscience by allowing spatially precise and high-resolution non-invasive targeting of both deep and superficial brain regions. Currently, fundamental research on the mechanisms of interaction between ultrasound and neural tissues is progressing in parallel with application-focused research. However, a major hurdle in the wider use of TUS is the selection of optimal parameters to enable safe and effective neuromodulation in humans. In this paper, we will discuss the major factors that determine the efficacy of TUS. We will discuss the thermal and mechanical biophysical effects of ultrasound, which underlie its biological effects, in the context of their relationships with tunable parameters. Based on this knowledge of biophysical effects, and drawing on concepts from radiotherapy, we propose a framework for conceptualising TUS dose.

A Novel Technology to Boost Natural Production of Hyaluronic Acid in the Skin Tissue: Human Histology Study

Article

作者: Goldberg, David J.

ABSTRACT:

Introduction:

Combining monopolar radiofrequency (RF) with targeted ultrasound (TUS), this study investigated whether these modalities promote facial rejuvenation through the production of hyaluronic acid (HA) in human skin.

Methods:

Seven subjects (51–64 years, BMI 21.1–29.8 kg/m2) were enrolled and divided into three treatment groups in this single‐center study; Group A (n = 3, simultaneous RF + TUS), Group B (n = 3, stand‐alone RF), and control (n = 1, no treatment). Both treated groups underwent four (4) 60‐min treatments on the face delivered 7–14 days apart. Punch biopsies (3 mm in diameter) were collected from the infra‐auricular area at baseline and both follow‐up visits and stained for HA by using hyaluronic acid binding protein. Digital photographs were taken to document changes in visual appearance. Finally, the subjects' comfort and satisfaction were assessed.

Results:

There was a statistically significant (p < 0.05) average increase at 1 month in the HA‐stained area of +112 358.7 μm2 in group A (RF + TUS) representing an increase of 48.65%. The treatment effect peaked at 3 months with an increase of +156 345.2 μm2, corresponding to a 67.69% increase in the HA‐stained area. In Group B, there was no significant difference in the average increase of the HA‐stained area between 1 month (+14 830 μm2) and 3 months (+20 995 μm2) corresponding to a 6.76% and 9.56% increase, respectively. The control samples did not indicate any changes throughout the study. Digital photographs of the RF + TUS group showed both a decrease in rhytids and tighter skin. Therapies were comfortable with no adverse events.

Conclusion:

Overall, this study has shown that the combination treatment of RF + TUS has a more pronounced and sustained effect on facial rejuvenation compared to RF alone. The measurable increase in the production of HA with simultaneous use of RF + TUS peaked at a 3‐month follow‐up, suggesting the gradual advancement of the treatment effect and overall improvement in facial appearance.

The association of lung consolidation and respiratory pathogens identified at weaning on the growth performance of beef-on-dairy calves

Article

作者: Felix, T L ; Renaud, D L ; Fernandes, I L B ; Sockett, D ; Cantor, M C ; Welk, A

This observational study evaluated the relationship between lung consolidation (LC) observed at weaning and calf ADG, and the association of pathogen shedding at weaning on ADG in beef × dairy calves up to 238 d. Beef × Holstein calves (n = 143) were sourced from 2 dairies. Calves were managed in 3 cohorts and fed milk replacer and calf starter before weaning. Calves were transported to another facility after weaning and raised in one group, where they were fed calf starter with oat hay and transitioned to a corn silage-based TMR diet. Calf ADG was calculated from arrival to weaning at 61 ± 14 d (period 1), from weaning to 83 ± 21 d (period 2), and from 83 d to 238 ± 21 d (period 3). Thoracic ultrasonography (TUS) was performed at weaning to evaluate if a calf had LC (characterized as TUS+ if ≥1 cm² in one lobe) and to categorize the degree of LC found (none [TUS-], 1-2 cm², or = 3 cm²). Nasopharyngeal swabs were taken from the TUS+ calves and from pair-matched TUS- calves (n = 35 pairs) for pathogen identification by culture at a diagnostic laboratory. A mixed linear regression model assessed the association of LC with calf ADG with LC, period, period × LC, and sire breed as fixed effects; arrival weight as a covariate; and calf nested within the cohort as a random effect. Another mixed linear regression model assessed the association of pathogen shedding with calf ADG from weaning to 238 d with period and sire breed as fixed effects, and pair was nested within cohort as a random effect. A logistic regression model was used to evaluate the likelihood of TUS+ calves shedding a pathogen with pair as a fixed effect. We found an LC × period interaction affecting ADG over period 2 where TUS- calves had increased ADG (1.18 ± 0.02 kg/d) compared with calves with LC = 3 cm² (1.03 ± 0.04 kg/d). However, TUS- calves had similar ADG to calves with LC = 1 to 2 cm² in period 2. Calf ADG was not associated with LC in period 3, and calves weighed 324 ± 37 kg (mean ± SD) at 238 d. In addition, 57% (20/35) of TUS+ calves and 26% (9/35) of TUS- calves shed Pasteurella multocida. We found no association of pathogen shedding with calf ADG, but TUS+ calves were more likely to shed a pathogen. These findings suggest that calves with pneumonia experienced poor growth up to 20 d postweaning, but compensatory gain occurred by 238 d. Furthermore, P. multocida was not associated with growth performance up to 238 d in beef × dairy calves.

Aptose Announces Dosing of First Patient with 120 mg of Tuspetinib in Phase 1/2 Tuscany Trial of Frontline Triple Drug Therapy after Dose Escalation Decision by Safety Review Committee

TUS+VEN+AZA triplet achieves complete remissions (CRs) and minimal residual disease (MRD)-negativity with favorable safety in newly diagnosed AML patients Completed 40 mg and 80 mg TUS dose cohorts; no prolonged myelosuppression or dose-limiting toxicities No dose reductions required to the standard-of-care therapy with 40 mg and 80 mg TUS dose cohorts CSRC endorsed escalation to 120 mg TUS dosing First patient dosed with 120 mg TUS triplet and enrollment continues SAN DIEGO and TORONTO, May 20, 2025 (GLOBE NEWSWIRE) -- Aptose Biosciences Inc. (“Aptose” or the “Company”) (OTC: APTOF, TSX: APS), a clinical-stage precision oncology company developing the tuspetinib (TUS)-based triple drug frontline therapy to treat patients with newly diagnosed AML, today announced that the Cohort Safety Review Committee (CSRC) monitoring Aptose’s Phase 1/2 TUSCANY trial of tuspetinib in combination with standard of care dosing of venetoclax and azacitidine (TUS+VEN+AZA triplet) has approved escalating from 80 mg dose TUS to 120 mg dose TUS based on its favorable review of safety and efficacy data from patients in the first two cohorts of the trial. Dosing of the first subject at the 120 mg TUS dose level has commenced. The TUS+VEN+AZA triplet is being developed as a one-of-a-kind, safe and mutation agnostic frontline therapy to treat large, mutationally diverse populations of newly diagnosed AML patients who are ineligible to receive induction chemotherapy. No significant safety concerns or dose limiting toxicities (DLTs) have been reported in the TUSCANY trial, including no prolonged myelosuppression of subjects in remission. Patients treated in the 40 mg and 80 mg dose cohorts remain on study while enrollment is open for the 120 mg dose cohort. Aptose has reported that the first two dose cohorts have demonstrated safety, CRs, and minimal residual disease (MRD) negativity across patients with diverse mutations (press release here). The Company will be presenting updated data in an oral presentation at the European Hematology Association Congress (EHA 2025), being held June 12-15, 2025, in Milan, Italy, which will include updated safety, CRs, MRD, and pharmacokinetic (PK) clinical findings and longer duration of follow up. “Data from the first two cohorts, with a 40 mg or 80 mg dose of TUS in the TUS+VEN+AZA triplet, reveal promising clinical safety and antileukemic activity even in some of the most difficult-to-treat AML populations,” said Rafael Bejar, M.D., Ph.D., Chief Medical Officer of Aptose. “With these significant findings, our CSRC – comprised of key leaders in the development of therapeutic agents for AML – recommended we dose escalate further, and we have now opened the 120 mg dose cohort of TUS in the triplet therapy.” TUSCANY: TUS+VEN+AZA Triplet Phase 1/2 Study The tuspetinib-based TUS+VEN+AZA triplet therapy is being advanced in the TUSCANY Phase 1/2 trial with the goal of creating an improved frontline therapy for newly diagnosed AML patients that is active across diverse AML populations, durable, and well tolerated. Earlier APTIVATE trials of TUS as a single agent and in combination as TUS+VEN demonstrated favorable safety and broad activity in diverse relapsed or refractory (R/R) AML populations that went beyond the more prognostically favorable NPM1 and IDH mutant subgroups. Indeed, responses were also in R/R AML patients with highly adverse TP53 and RAS mutations, and those with mutated or unmutated (wildtype) FLT3 genes. The TUSCANY triplet Phase 1/2 study, being conducted at 10 leading U.S. clinical sites by elite clinical investigators, is designed to test various doses and schedules of TUS in combination with standard dosing of AZA and VEN for patients with AML who are ineligible to receive induction chemotherapy. A convenient, once daily oral agent, TUS is being administered in 28-day cycles. Multiple U.S. sites are enrolling in the TUSCANY trial with anticipated enrollment of 18-24 patients by mid-late 2025. Data will be released as it becomes available. More information on the TUSCANY Phase 1/2 study can be found on www.clinicaltrials.gov (here). About Aptose Aptose Biosciences is a clinical-stage biotechnology company committed to developing precision medicines addressing unmet medical needs in oncology, with an initial focus on hematology. The Company’s lead clinical-stage, oral kinase inhibitor tuspetinib (TUS) has demonstrated activity as a monotherapy and in combination therapy in patients with relapsed or refractory acute myeloid leukemia (AML) and is being developed as a frontline triplet therapy in newly diagnosed AML.

使“癌症之王”患者总生存期优于历史对照的小分子疗法；使多名患者肿瘤完全消失的组合疗法…… | 一周盘点

本期看点1. 在一项早期临床试验中，tuspabetinib（TUS）联用标准剂量的venetoclax和azacitidine的三联疗法使多名急性髓系白血病（AML）患者的肿瘤细胞完全消失。2. 放射增敏剂JNJ-1900用于局部晚期或临界可切除胰腺癌患者的1期临床试验结果亮眼，患者的中位总生存期（OS）优于历史对照组，并有两名患者成功实现R0根治性手术切除。3. 大环MEK抑制剂PAS-004的药效学（PD）数据积极，对评估MEK抑制剂活性的金标准PD生物标志物的抑制率高达91%。药明康德内容团队整理Tuspetinib：公布1/2期联合治疗试验的新数据Aptose Biosciences公司公布了其针对新确诊的AML患者开展的1/2期TUSCANY试验的新数据。这些患者分别接受了40毫克或80毫克剂量的tuspabetinib联用标准剂量的venetoclax和azacitidine（TUS+VEN+AZA三联疗法）。该三联疗法正在被开作发为一种安全且不依赖于特定突变的一线治疗方案，用于治疗那些无法接受诱导化疗的新诊断AML患者，这些患者具有多样的突变。在两种剂量下，均有多名携带不同突变（包括TP53突变/复杂核型、FLT3野生型）的患者达到了完全缓解（CR）或伴有血液学不完全恢复的完全缓解（CRi），40毫克剂量组中达到CR/CRi的3名患者的最小残留病（MRD）状态均为阴性。安全性方面，该三联疗法的安全性良好，在两个剂量水平下均未观察到剂量限制性毒性。JNJ-1900（NBTXR3）：公布1期临床试验数据Nanobiotix公司公布了其潜在“first-in-class”的新型放射增敏剂JNJ-1900（NBTXR3）用于局部晚期或临界可切除胰腺癌患者的1期临床试验数据。NBTXR3由功能化二氧化铪（HfO2）纳米颗粒组成，经由一次性瘤内注射给药并通过放射疗法激活。它的物理作用机制为：通过放疗激活，诱导被注射肿瘤内大量的肿瘤细胞死亡，随后触发适应性免疫反应和长期的抗癌记忆。得益于该物理作用机制，Nanobiotix公司认为NBTXR3可扩展到任何可以通过放疗治疗的实体肿瘤和任何联合治疗方案中，特别是与免疫检查点抑制剂联合。2023年，Nanobiotix宣布与强生旗下杨森公司（现名为强生创新制药）达成全球共同开发和商业化NBTXR3的许可协议。此次公布的研究结果显示，22名接受JNJ-1900治疗的患者的中位OS达到23个月（从诊断日期开始计算），优于历史对照组（19.2个月）；中位局部无进展生存期（PFS）为13.3个月（从放疗结束时开始计算）；两名患者成功实现R0根治性手术切除。探索性生物标志物分析显示，循环肿瘤突变负荷（cTMB）升高与更长的局部PFS和OS相关；CA19-9肿瘤标志物在59%的患者中恢复正常，同样与更长的OS相关。这些结果支持在随机对照试验中进一步评估JNJ-1900。PAS-004：公布1期临床试验数据Pasithea Therapeutics公司公布了其大环MEK抑制剂PAS-004治疗MAPK通路驱动的晚期实体肿瘤患者的1期临床研究的PD数据。与目前FDA批准的MEK抑制剂不同，PAS-004是大环化合物，环化可增强药物与靶受体的结合，被认为有望改善药代动力学和安全性。ERK磷酸化（pERK）的抑制被广泛认为是评估MEK抑制剂活性的金标准PD生物标志物。为了评估PAS-004的靶点作用，研究人员在基线和第22天稳态时检测了患者外周血单核细胞（PBMCs）中的pERK水平。结果显示，PAS-004对pERK的抑制率高达91%，证实其具有强大的靶点作用。该结果得到了初步临床观察的支持，表现为多名患者实现了疾病稳定（SD）和肿瘤缩小。其中，一名IV期携带KRAS G12R突变的胰腺癌患者已获得超过5个月的SD，肿瘤体积缩小了9.8%。REC-4881：公布1b/2期临床试验数据Recursion公司公布了其正在进行的1b/2期TUPELO试验中REC-4881的初步安全性和疗效结果。REC-4881是一种正在被开发用于治疗家族性腺瘤性息肉病（FAP）的选择性变构MEK1/2抑制剂。FAP是一种由APC基因突变引起的罕见遗传性疾病，患者若不治疗，几乎100%会发展为结直肠癌。目前，该病尚无获得美国FDA批准的治疗方法。REC-4881已获得FDA和欧洲药品管理局授予的孤儿药资格及FDA的快速通道资格。截至2025年3月17日的数据，在接受4 mg每日一次治疗的6例可评估患者中，第13周时息肉负荷的中位降幅为43%，其中83%的患者（5人）的降幅范围为31%至82%，1例患者的息肉负荷较基线大幅增加。50%的患者实现了Spigelman分期（衡量上消化道疾病严重程度的指标）改善≥1分。REC-4881的早期安全性特征与以往的MEK1/2抑制剂相似。在1b期和2期研究里的19名患者中，大多数治疗相关不良事件为1/2级，16%的患者发生了3级不良事件，目前未报告任何4级及以上的治疗相关不良事件。JANX007：启动1b期扩展研究Janux Therapeutics公司宣布在未接受过紫杉烷类药物的转移性去势抵抗性前列腺癌（mCRPC）患者中启动1b期扩展研究，该研究的启动得到了此前公布的1a期剂量递增研究数据的支持。JANX007是一款靶向前列腺特异性膜抗原（PSMA）的肿瘤激活T细胞接合器，分别靶向PSMA和T细胞表面表达的CD3受体。它的设计让JANX007在肿瘤微环境中经过蛋白酶切割而被激活，从而在降低了其潜在毒性的同时，最大化抗肿瘤免疫反应。截至2025年4月21日的数据，16名mCRPC患者的中位影像学PFS为7.5个月，6个月时的影像学无进展生存率为65%；接受6 mg和9 mg治疗剂量的9名患者的中位影像学PFS为7.9个月，6个月时的影像学无进展生存率为78%。安全性数据与2024年12月披露的数据保持一致。SPY001：公布1期临床试验的新数据Spyre Therapeutics公司公布了其抗体疗法SPY001的1期临床试验的新数据。SPY001是一种高效、具有选择性的抗α4β7单克隆抗体，采用工程化改造延长半衰期，正在被开发用于治疗炎症性肠病（IBD）。长达8个月的随访结果显示，SPY001具有良好的耐受性，药代动力学（PK）数据显示，其半衰期长达约80天，是现有标准治疗之一的vedolizumab的三倍以上。PD数据显示，在预期的2期谷浓度，单次给药SPY001仍能维持对靶点的持续作用，导致α4β7受体快速、持续饱和。该数据进一步支持SPY001在更高暴露量下可能实现更优的诱导治疗反应，以及具有每季度或每半年给药一次的潜力。参考资料：[1] Perfuse Therapeutics Announces Positive Results from the Completed Phase 1/2a Clinical Trial of PER-001 Intravitreal Implant in Patients with Glaucoma.
