The combination is the lead Phase 3 obesity programme in Novo Nordisk&#8217;s pipeline and reported the REDEFINE-1 trial results in 2024\u20132025: approximately 20\u201323% body-weight reduction over 68 weeks at the 2.4\u00a0mg + 2.4\u00a0mg weekly dose \u2014 effect sizes that place CagriSema in the same range as the triple-receptor-agonist <a href=\"https:\/\/medsbase.com\/nl\/retatrutide\/\">retatrutide<\/a> while taking a completely different pharmacological route.<\/p>\n<p>The strategic rationale for CagriSema rests on the <strong>complementary, non-overlapping mechanisms<\/strong> of its two component peptides. GLP-1 receptor agonists (semaglutide) act predominantly on hypothalamic arcuate-nucleus POMC neurons (central appetite regulation) and pancreatic beta-cells (glucose-dependent insulin secretion). Amylin\/calcitonin receptor agonists (cagrilintide) act predominantly on brainstem area-postrema neurons (per-meal satiety reinforcement) and pancreatic alpha-cells (glucagon suppression). The two mechanisms are mechanistically additive rather than redundant, which is why the combination produces body-weight effects substantially greater than either component alone \u2014 demonstrated in the Phase 2 head-to-head data where CagriSema outperformed both cagrilintide monotherapy and semaglutide monotherapy.<\/p>\n<p>This research-grade CagriSema co-formulation contains <strong>5\u00a0mg cagrilintide + 5\u00a0mg semaglutide per vial<\/strong> in a 1:1 mass ratio matching the fixed-dose ratio used in the Phase 3 clinical programme. Both components are pre-mixed in the same lyophilized vial; reconstitution with bacteriostatic water yields a working solution containing both peptides simultaneously. This approach eliminates the need to combine separate vials at the bench. CagriSema is <strong>niet goedgekeurd<\/strong> by the FDA, EMA, MHRA, or any other major regulator for human therapeutic use as of current literature; regulatory submission and review are ongoing. The research-grade CagriSema sold here is supplied <strong>uitsluitend voor laboratoriumonderzoek<\/strong> and is not intended for human or veterinary administration.

This arm provides the canonical incretin pharmacology that semaglutide and other GLP-1 agonists are known for in published research and approved clinical use.<\/li>\n<li><strong>Amylin \/ calcitonin receptor arm (cagrilintide) \u2014 brainstem satiety and per-meal feedback<\/strong> \u2014 Cagrilintide activates the amylin receptor heterodimers (AMY1, AMY2, AMY3 \u2014 calcitonin receptor + RAMP1\/2\/3) located densely in the brainstem area postrema, a CNS region that lacks a blood-brain barrier. This produces per-meal satiety reinforcement on a different temporal pattern than GLP-1&#8217;s tonic central appetite suppression. The amylin arm also delays gastric emptying via a partly distinct vagal pathway and suppresses postprandial glucagon at pancreatic alpha-cells.<\/li>\n<li><strong>Additive vs synergistic effect on body-weight phenotype<\/strong> \u2014 The Phase 2 head-to-head data are the cleanest evidence of additive (and possibly synergistic) pharmacology: cagrilintide monotherapy at 2.4\u00a0mg weekly produced ~10% body-weight reduction; semaglutide monotherapy at 2.4\u00a0mg weekly produced ~15%; the CagriSema combination at 2.4 + 2.4 mg produced ~20\u201323%. The net effect approaches or exceeds the sum of the individual effects, consistent with the mechanistic prediction that two non-overlapping satiety pathways activated simultaneously produce a stronger anorectic signal than either alone.<\/li>\n<\/ul>\n<p>Both peptides are acylated with fatty-diacid chains that bind reversibly to circulating serum albumin (cagrilintide uses a C20 chain via \u03b3-Glu-OEG-OEG; semaglutide uses C18 via \u03b3-Glu-AEEA-AEEA). The half-lives are well matched at ~159 hours (cagrilintide) and ~165 hours (semaglutide) \u2014 both supporting once-weekly subcutaneous dosing without divergent pharmacokinetics. This pharmacokinetic alignment is one of the design features that makes co-formulation in a single vial practical: the two components can be reconstituted, stored, and dosed together without compromising either&#8217;s exposure profile.<\/p>\n<h2>Gepubliceerde onderzoeksapplicaties<\/h2>\n<p>CagriSema co-formulation research peptides are used in laboratory contexts that investigate:<\/p>\n<ul>\n<li><strong>Combination obesity pharmacology<\/strong> \u2014 the lead programme: preclinical DIO rodent models, body-composition (DEXA\/MRI), food-intake assays, energy-expenditure characterisation; head-to-head against monotherapy arms (cagrilintide alone, semaglutide alone) to dissect the additive vs synergistic question (Enebo et al., Lancet 2021; REDEFINE-1 \/ REDEFINE-2 Phase 3 results)<\/li>\n<li><strong>Type 2 diabetes preclinical research<\/strong> \u2014 glycaemic control, HbA1c surrogates, postprandial glucose dynamics in db\/db and high-fat-diet rodent models<\/li>\n<li><strong>Comparative multi-agonist research<\/strong> \u2014 head-to-head with single-molecule multi-agonists including <a href=\"https:\/\/medsbase.com\/nl\/tirzepatide\/\">Tirzepatide<\/a> (dual GLP-1\/GIP), <a href=\"https:\/\/medsbase.com\/nl\/retatrutide\/\">Retatrutide<\/a> (triple GLP-1\/GIP\/glucagon), <a href=\"https:\/\/medsbase.com\/nl\/mazdutide\/\">Mazdutide<\/a> (dual GLP-1\/glucagon), and <a href=\"https:\/\/medsbase.com\/nl\/survodutide\/\">Survodutide<\/a> (dual GLP-1\/glucagon); the central question is whether combination-of-two-molecules pharmacology has any advantage over single-multi-agonist molecules<\/li>\n<li><strong>Amylin \/ GLP-1 axis interaction research<\/strong> \u2014 non-overlapping mechanism characterisation, brainstem-vs-hypothalamic central appetite circuit dissection, simultaneous receptor occupancy assays<\/li>\n<li><strong>Gastric emptying and postprandial physiology<\/strong> \u2014 gastric emptying time under combined vs individual treatment, postprandial glucose dynamics, gut-hormone-axis integration<\/li>\n<li><strong>Energy expenditure research<\/strong> \u2014 resting energy expenditure, respiratory exchange ratio; the CagriSema combination produces a distinct profile from glucagon-receptor-containing multi-agonists (mazdutide, retatrutide) because neither component activates the glucagon receptor<\/li>\n<li><strong>Combination-pharmacology design research<\/strong> \u2014 CagriSema as a case study in fixed-ratio multi-peptide formulation, comparison of co-formulation pharmacokinetics vs sequential or co-administered separate vials.<\/li>\n<\/ul>\n<p>For broader context, see our individual <a href=\"https:\/\/medsbase.com\/nl\/cagrilintide\/\">Cagrilintide<\/a> en <a href=\"https:\/\/medsbase.com\/nl\/semaglutide\/\">Semaglutide<\/a> product pages for component-level pharmacology, <a href=\"https:\/\/medsbase.com\/nl\/retatrutide\/\">Retatrutide<\/a> as the principal single-molecule triple-agonist alternative, and <a href=\"https:\/\/medsbase.com\/nl\/tirzepatide\/\">Tirzepatide<\/a> as the dual GLP-1\/GIP comparator.

For unopened long-term storage, freeze at \u221220\u00a0\u00b0C. The lyophilized CagriSema co-formulation is stable under refrigeration for up to 24 months and at \u221220\u00a0\u00b0C for up to 36 months. Both component peptides have closely-matched stability profiles, so storage is governed by whichever peptide degrades first under given conditions \u2014 in practice, the two components are remarkably similar. Avoid freeze-thaw cycles on the lyophilized powder.<\/p>\n<p><strong>Reconstitueringsprocedure:<\/strong> inject bacteriostatic water down the side wall of the vial (not directly onto the lyophilized cake). Because the vial contains 10\u00a0mg total peptide mass (5\u00a0mg cagri + 5\u00a0mg sema), a 2.0\u00a0mL reconstitution yields a 5\u00a0mg\/mL total-peptide working concentration \u2014 equivalent to 2.5\u00a0mg\/mL of each individual component. Approximately 0.96\u00a0mL delivers a 2.4\u00a0mg + 2.4\u00a0mg clinical-equivalent research dose. Swirl gently \u2014 do <strong>niet<\/strong> shake \u2014 and allow 5\u201310 minutes for full dissolution (both peptides are acylated and dissolve more slowly than smaller unmodified peptides). A correctly reconstituted solution should be clear and colourless with no visible particles.<\/p>\n<p><strong>Na reconstitutie:<\/strong> store refrigerated at 2\u20138\u00a0\u00b0C and use within 30 days for optimal stability of both components. Do not freeze the reconstituted solution \u2014 freeze-thaw cycles degrade peptide integrity and could disproportionately affect either component. Discard any vial showing cloudiness, precipitate, or discolouration.<\/p>\n<h2 id=\"faqs\">Veelgestelde vragen<\/h2>\n<h3>What is CagriSema used for in research?<\/h3>\n<p>CagriSema is used in laboratory research investigating the additive pharmacology of GLP-1 and amylin receptor activation, combination obesity pharmacology, type 2 diabetes preclinical models, comparative head-to-head studies against single-molecule multi-agonists (tirzepatide, retatrutide, mazdutide, survodutide), and combination-pharmacology design questions.

CagriSema combines two separate single-receptor agonists (cagrilintide + semaglutide) in one vial \u2014 combination pharmacology. <a href=\"https:\/\/medsbase.com\/nl\/retatrutide\/\">Retatrutide<\/a> engineers triple-receptor pharmacology (GLP-1 + GIP + glucagon) into a single molecule. Both reach approximately 20\u201324% body-weight effect at maintenance dose in Phase 2\/3 research, but through different receptor sets \u2014 CagriSema uses GLP-1 + amylin, retatrutide uses GLP-1 + GIP + glucagon.<\/p>\n<h3>Why combine the two peptides in a single vial?<\/h3>\n<p>Co-formulation has three practical advantages: (1) the half-lives of cagrilintide (~159 h) and semaglutide (~165 h) are well-matched, so a single weekly injection delivers both peptides on the same pharmacokinetic schedule; (2) reconstitution is simpler \u2014 one vial, one diluent volume, one withdrawal; (3) fixed-dose-ratio research is straightforward because the dose ratio is set at manufacture and cannot drift between separate vial draws. The principal trade-off is that the dose ratio is fixed at 1:1 mass \u2014 for research requiring different ratios, separate vials of <a href=\"https:\/\/medsbase.com\/nl\/cagrilintide\/\">cagrilintide<\/a> en <a href=\"https:\/\/medsbase.com\/nl\/semaglutide\/\">semaglutide<\/a> may be preferred.<\/p>\n<h3>What is the typical CagriSema research dose?<\/h3>\n<p>Published Phase 3 clinical research uses 2.4\u00a0mg cagrilintide + 2.4\u00a0mg semaglutide weekly as the maintenance dose, with a multi-month titration schedule starting at 0.25\u00a0mg + 0.25\u00a0mg. A vial reconstituted with 2.0\u00a0mL bacteriostatic water yields 2.5\u00a0mg\/mL of each component (5\u00a0mg\/mL total peptide mass) \u2014 approximately 0.96\u00a0mL equals a clinical-equivalent 2.4\u00a0mg + 2.4\u00a0mg research dose.<\/p>\n<h3>Is CagriSema FDA approved?<\/h3>\n<p>No. CagriSema is not approved by the FDA, EMA, MHRA, or any other major regulator for human therapeutic use. The REDEFINE-1 (obesity) and REDEFINE-2 (T2DM) Phase 3 trials reported positive results in 2024\u20132025, but regulatory submission and review are ongoing. All CagriSema sold by research-use-only suppliers is for laboratory investigation and should not be administered to humans.<\/p>\n<h3>How should CagriSema be stored?<\/h3>\n<p>Lyophilized vials: refrigerated at 2\u20138\u00a0\u00b0C for short-term working stock, or \u221220\u00a0\u00b0C for long-term storage of unopened vials. Reconstituted solution: refrigerated at 2\u20138\u00a0\u00b0C, use within 30 days. Do not freeze reconstituted solution \u2014 freeze-thaw cycles degrade peptide integrity and could disproportionately affect either component. Protect from direct light at all times.<\/p>\n<h3>How do I reconstitute CagriSema?<\/h3>\n<p>Follow the reconstitution procedure above. Add bacteriostatic water down the side wall of the vial (not onto the lyophilized cake), swirl gently, and allow 5\u201310 minutes for full dissolution (both peptides are acylated and dissolve more slowly than smaller unmodified peptides). Do <strong>niet<\/strong> shake the vial. Both peptides reconstitute simultaneously from the same vial. A correctly reconstituted solution is clear and colourless with no visible particles. For a vial + 2.0\u00a0mL diluent, the working concentration is 2.5\u00a0mg\/mL of each peptide.<\/p>\n<h3>What configurations does MedsBase stock?<\/h3>\n<p>MedsBase carries the CagriSema co-formulation in a single composition: 5\u00a0mg cagrilintide + 5\u00a0mg semaglutide per vial (1:1 mass ratio, lyophilized). The vial is available in 10-vial or 20-vial pack sizes. Each component is verified individually at \u226599% HPLC purity with a certificate of analysis available on request.<\/p>\n<h3>Can I buy CagriSema components separately instead?<\/h3>\n<p>Yes \u2014 MedsBase stocks both component peptides as stand-alone products: <a href=\"https:\/\/medsbase.com\/nl\/cagrilintide\/\">Cagrilintide<\/a> in 5\u00a0mg and 10\u00a0mg vials, and <a href=\"https:\/\/medsbase.com\/nl\/semaglutide\/\">Semaglutide<\/a> in 2\u201350\u00a0mg vials. Separate vials are useful if research protocols require dose ratios other than the clinical 1:1 mass ratio, or if researchers want to dose cagrilintide and semaglutide independently. The co-formulated blend offers a small bundle saving and the convenience of single-vial reconstitution for protocols at the 1:1 clinical ratio.<\/p>\n<h3>Does CagriSema cause side effects in research?<\/h3>\n<p>The side-effect profile of CagriSema in Phase 3 research is dominated by gastrointestinal findings shared with both component peptides: nausea, transient appetite suppression, and delayed gastric emptying are dose-dependent and tend to attenuate over 4\u20138 weeks of continuous dosing. The combined regimen does not produce qualitatively different side effects from either component alone \u2014 the GI-axis tolerability is roughly comparable to semaglutide monotherapy at equivalent doses.<\/p>\n<h3>What is the half-life of CagriSema?<\/h3>\n<p>Both component peptides have closely-matched plasma half-lives: cagrilintide ~159 hours (~6.5 days) and semaglutide ~165 hours (~7 days). The matching is one of the design features that makes co-formulation in a single vial practical \u2014 both peptides clear from circulation on the same schedule, supporting once-weekly dosing without divergent pharmacokinetics. The albumin-binding mechanism (C20 \/ C18 fatty-acid acylation) is the basis for the extended half-life in both peptides.<\/p>\n<h3>How long does CagriSema take to show effects in preclinical research?<\/h3>\n<p>Acute pharmacodynamic effects on gastric emptying, per-meal satiety, and glucose tolerance are detectable within hours of the first dose. Body-weight effects in DIO rodent models typically become statistically significant after 1\u20132 weeks of weekly dosing and continue to accrue through 16\u201324 weeks. Maximum effect on body composition develops over 48\u201368 weeks, matching the REDEFINE-1 Phase 3 trajectory.<\/p>\n<h3>Can I order CagriSema for international shipping?<\/h3>\n<p>Yes.
