"Our Switch-DARPin platform provides a novel approach to tumor-localized T-cell engagement and costimulation through its logic-gated on/off Switch mechanism. We are excited to have the opportunity to add this MoA to our validated CD3 T cell engager approach," said Patrick Amstutz, Ph.D., CEO of Molecular Partners. "We hope to open therapeutic avenues for co-stimulating T-cell engagers, by rendering them silent in the circulation and activating them at the tumor site."

我們的交換機-DARPin平台通過其邏輯門控制的開關機制,爲腫瘤定位t細胞參與和共刺激提供了一種新穎的方法。我們很高興有機會將這種作用機制添加到我們經過驗證的CD3萬億細胞參與者方法中,"Molecular Partners首席執行官Patrick Amstutz博士表示。"我們希望爲共刺激t細胞參與者開闢治療途徑,使其在循環中保持沉默,並在腫瘤部位激活它們。"

CD3 Switch-DARPin: Preclinical proof-of-concept for T cell engager with enhanced function in solid tumors

CD3交換機-DARPin:對固體腫瘤中功能增強的t細胞參與者的臨床前概念驗證

The Switch-DARPin platform provides a logic-gated "on/off" function (the "Switch") to multispecific DARPin candidates leading to immune activation only in the presence of defined antigens. This allows targeting the immune activation to tumors, increasing both efficacy and safety and opening up new opportunities for cancer treatment. T cell engagers (TCE) are a powerful class of immuno-oncology therapies but have faced a range of challenges such as high toxicity and limited specificity, particularly against solid tumors. By employing a multi-specific Switch-DARPin, Molecular Partners aims to bring additional dimensions of safety and potency to the fundamental TCE mechanism.

Switch-DARPin平台爲多特異性DARPin候選藥物提供了邏輯門控制的「開關」功能,只有在存在定義的抗原時才導致免疫活化。這允許將免疫激活定位到腫瘤,提高療效和安全性,爲癌症治療開闢新機會。t細胞參與者(TCE)是一類強大的免疫腫瘤學療法,但面臨着一系列挑戰,如高毒性和有限的特異性,特別是對抗固體腫瘤。Molecular Partners通過使用多特異性Switch-DARPin,旨在爲基本的TCE機制增加額外的安全性和效力。

The data to be presented at SITC provide further validation of the Company's Switch-DARPin platform and preclinical proof-of concept that conditional T cell activation in solid tumors is feasible, as exemplified in preclinical ovarian cancer models. The presented multi-specific Switch-DARPin molecule comprises DARPins targeting:

在SITC上呈現的數據進一步驗證了公司的Switch-DARPin平台以及在固體腫瘤中有條件地激活t細胞的臨床前概念的可行性,如在臨床前卵巢癌模型中展示的。呈現的多特異性Switch-DARPin分子包括定位DARPins:

  1. CD3, to engage and activate T cells
  2. CD2, a co-stimulator of CD3 on T cells
  3. Mesothelin, a notable tumor antigen overexpressed across several cancer types, including ovarian cancer, and used as anchoring target for the Switch-DARPin
  4. And the Switch-DARPin, which binds either to the tumor antigen EpCAM or to the CD3 DARPin mentioned above. In a default state, the whole molecule is in closed state (or Switched off), masking the CD3 DARPin and preventing immune activation. When tumor antigens mesothelin and EpCAM are present, the Switch-DARPin "switches" to bind EpCAM instead of the CD3 DARPin, thereby freeing the CD3 DARPin and allowing it to bind and activate T cells. T cell activation is further enhanced through co-stimulation by the CD2 DARPin.
  1. CD3是參與和激活T細胞的
  2. CD2是T細胞上CD3的共刺激因子
  3. Mesothelin是一種顯著的腫瘤抗原,在多種癌症類型中過度表達,包括卵巢癌,並用作Switch-DARPin的錨定靶點
  4. Switch-DARPin可以結合腫瘤抗原EpCAm或上述CD3 DARPin。在默認狀態下,整個分子處於關閉狀態(或關斷狀態),掩蓋了CD3 DARPin並阻止免疫激活。當腫瘤抗原Mesothelin和EpCAm同時存在時,Switch-DARPin會"轉變"以結合EpCAm,而不是CD3 DARPin,從而釋放CD3 DARPin並允許其結合並激活T細胞。通過CD2 DARPin的共刺激,T細胞的激活進一步增強。

This CD3 Switch-DARPin molecule effectively induces potent tumor regression in vivo, with reduced cytokine release, a significant toxicity event for TCEs in the clinic, compared to an unmasked CD3 with CD2 co-stimulation. In addition, co-engagement of CD2 leads to sustained T cell activation and cytotoxic capacity. Finally, masking of CD3 prevents T cell activation in the absence of tumor antigens, hence potentially allowing for "silent" TCEs outside of tumors. Taken together, masking CD3 may reduce the risk of CRS and provide a better safety profile to TCEs.

這種CD3 Switch-DARPin分子在體內有效誘導強效的腫瘤消退,與在臨床中未掩蓋的CD3和CD2共刺激相比,細胞因子釋放減少,這是TCEs的一個重大毒性事件。此外,CD2的共同參與導致T細胞的持續激活和細胞毒能力。最後,CD3的掩蓋防止了在缺乏腫瘤抗原的情況下T細胞的激活,因此可能允許腫瘤之外的"隱形"TCEs。總的來說,掩蓋CD3可能降低CRS的風險,併爲TCEs提供更好的安全性特點。

MP0317: Comprehensive biomarker data further support CD40 activation locally in tumor microenvironment

MP0317:全面的生物標誌物數據進一步支持CD40在腫瘤微環境中的局部激活

MP0317 is a CD40 agonist designed to activate immune cells specifically within the tumor microenvironment (TME) by anchoring to fibroblast activation protein (FAP) which is expressed in high amounts in the stroma of various solid tumors. This tumor-localized approach has the potential to deliver greater efficacy with fewer side effects compared to systemic CD40-targeting therapies.

MP0317是一種CD40激動劑,旨在通過與各種實體瘤基質中高濃度表達的成纖維細胞激活蛋白(FAP)結合,特異性地激活腫瘤微環境(TME)內的免疫細胞。這種腫瘤局部化治療方法有潛力在與全身性CD40靶向療法相比,提供更高的療效並減少副作用。

The poster presents the results of a comprehensive biomarker analyses from the completed Phase 1 multi-center, open label, dose-escalation trial of MP0317 monotherapy in patients with advanced solid tumors. The research further demonstrates the ability of MP0317 to induce a targeted, tumor-localized CD40 activation and its suitability for Q3W (every three weeks) and Q1W (weekly) dosing. The CD40 pathway is activated in a broad-spectrum of cancer types and various tumor locations. Evidence of TME remodeling in patients treated with pharmacologically active doses is exemplified by increases in dendritic cells, M1 macrophages, plasma cells, and T follicular helper cells, as well as IFNγ downstream activation and an increased dendritic cell maturation gene signature score. Peripheral pharmacodynamic effects aligned with the MP0317 mode of action are also seen, including increases in CXCL10 chemoattractant, transient B-cell reduction, and activation in blood.

該海報展示了在已完成的Phase 1多中心、開放標籤、劑量遞增試驗中,對MP0317單藥治療晚期實體瘤患者的全面生物標誌物分析結果。研究進一步證明了MP0317誘導靶向腫瘤局部化CD40激活的能力,以及其適用於Q3W(每三週一次)和Q1W(每週一次)的劑量。CD40途徑在廣譜的癌症類型和各種腫瘤部位中被激活。與藥理活性劑量治療的患者中TME重塑的證據體現在樹突狀細胞、M1巨噬細胞、漿細胞和T輔助細胞的增加,以及IFNγ下游激活和樹突狀細胞成熟基因特徵得分增加。與MP0317作用模式一致的外周藥效效應也可見,包括CXCL10趨化因子的增加、短暫的B細胞減少以及在血液中的激活。

Molecular Partners is in discussion with leading academic centers regarding potential investigator-initiated combination trials of MP0317.

About DARPin Therapeutics
DARPin (Designed Ankyrin Repeat Protein) therapeutics are a new class of custom-built protein drugs based on natural binding proteins that open new dimensions of multi-functionality and multi-target specificity in drug design. The flexible architecture, intrinsic potential for high affinity and specificity, small size and high stability of DARPins offer benefits to drug design over other currently available protein-based therapeutics. DARPin candidates can be radically simple, with a single DARPin unit acting as the delivery vector to a specific target; or multispecific, with the possibility of engaging more than five targets, and combining multiple and conditional functionalities in a unique DARPin drug candidate. The DARPin platform is designed to be a rapid and cost-effective drug discovery engine, producing drug candidates with optimized properties and high production yields. DARPin therapeutics have been clinically validated across several therapeutic areas and developed through to the registrational stage.
