Roche entered the obesity race late and is moving fast. The 2024 Carmot Therapeutics acquisition brought in CT-388 (now enicepatide) — a dual GLP-1/GIP receptor agonist that posted 22.5% placebo-adjusted weight loss in Phase 2. The 2025 Zealand Pharma partnership added petrelintide, the long-acting amylin analog that delivered double-digit weight loss with placebo-like tolerability in ZUPREME-1.
The Q1 2026 print clarified the pipeline cadence: ENITH 1 and ENITH 2, the two Phase 3 enicepatide obesity trials, were both initiated in Q1; the petrelintide+enicepatide fixed-dose combination Phase 2 starts mid-2026; and additional Phase 2 readouts for oral GLP-1 CT-996 are guided before year-end. Roche executives projected $9B in peak sales for the obesity pipeline and confirmed petrelintide and enicepatide ADA 2026 data presentations in June. On April 30, Zealand and Roche announced petrelintide's formal advancement to Phase 3 in chronic weight management.

Roche announced on Tuesday, September 22, 2026 that enicepatide (CT-388), an investigational once-weekly GLP-1/GIP receptor agonist, met both primary endpoints in the randomized, placebo-controlled Phase 2 CT-388-104 trial in 447 adults with type 2 diabetes and overweight or obesity. At the highest titrated dose of 24 mg, HbA1c fell 2.65 percentage points from a baseline of 8.1%, mean weight loss was 15.5% at 48 weeks with no plateau, and 90% of patients on that dose reached an HbA1c of 6.5% or lower. Discontinuation due to adverse events was 2.0% across enicepatide arms versus 0.0% on placebo, and side effects were mostly mild-to-moderate gastrointestinal. Roche's announcement did not give placebo results for weight or HbA1c; the company plans a Phase 3 glycemic-control program and cardiovascular outcomes trials in the first half of 2027, alongside the ongoing ENITH-1 and ENITH-2 weight-management trials.
Zealand Pharma announced on September 22, 2026 the start of the Phase 3a ZUPREME program for petrelintide, its once-weekly subcutaneous amylin analog partnered with Roche. The three placebo-controlled trials are ZUPREME-3 (about 3,900 people with overweight or obesity and at least one weight-related comorbidity, without type 2 diabetes), ZUPREME-4 (about 600 people with type 2 diabetes), and ZUPREME-5 (about 2,500 people with established cardiovascular disease). Each trial's primary endpoint is percentage change in body weight from baseline to week 64. A Phase 2 trial combining petrelintide with Roche's GLP-1/GIP agonist enicepatide (CT-388) is planned for the second half of 2026.
Roche said on September 23, 2026 that a prespecified interim analysis of the Phase 3 IMAgINATION trial found sefaxersen produced a statistically significant reduction in 24-hour urine protein-to-creatinine ratio versus placebo at 37 weeks in adults with primary IgA nephropathy at high risk of progression. The trial randomized 459 people 1:1 to sefaxersen, a once-monthly subcutaneous antisense drug that reduces liver production of complement factor B, or to placebo for 105 weeks. Roche did not disclose the size of the proteinuria reduction; the trial remains blinded to week 105 to measure change in eGFR, and safety was consistent with prior data. Roche licensed sefaxersen from Ionis.
Roche announced on Thursday, September 17, 2026 that the Phase 3 CELESTIMO trial met its primary endpoint: Lunsumio (mosunetuzumab) plus lenalidomide produced a statistically significant improvement in progression-free survival versus rituximab plus lenalidomide in people with relapsed or refractory follicular lymphoma who had received at least one prior line of treatment. Overall survival data were immature at the interim analysis, and safety was consistent with the known profiles of both drugs, with no new signals. CELESTIMO is the confirmatory study required to convert the accelerated approval and conditional authorization of Lunsumio monotherapy for third-line or later follicular lymphoma into full approval. Roche will submit the data to health authorities and present them at an upcoming medical meeting.
Dualitas Therapeutics announced on Thursday, September 17, 2026 a research collaboration and license agreement with Roche to discover bispecific antibodies for immunology and inflammation diseases. Dualitas receives $36.5 million upfront and can earn research, development, and commercial milestones plus tiered royalties, for a total potential value of up to $1 billion. It will use its DualScreen Bispecific Discovery Engine to functionally screen more than 300,000 novel bispecific combinations, and Roche will handle all later preclinical development, regulatory, manufacturing, and commercial work.
Roche (SIX: RO, ROG; OTCQX: RHHBY) announced Thursday September 10, 2026 that the FDA granted Priority Review to a supplemental Biologics License Application (sBLA) for Enspryng (satralizumab, a humanized anti-interleukin-6 receptor monoclonal antibody using recycling-antibody technology for extended IL-6 receptor blockade) for the treatment of myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD). MOGAD is a rare inflammatory central nervous system disorder attacking optic nerves, brain, and spinal cord with estimated prevalence of 0.51 to 3.42 per 100,000 people. It has no FDA-approved disease-modifying treatments. The Phase 3 METEOROID trial met its primary endpoint of time to first relapse during double-blind treatment with a 68% reduction in relapse risk versus placebo (p=0.0025) and secondary endpoints including 87% of Enspryng-treated patients relapse-free at 48 weeks (versus 67% on placebo), 66% lower annualized relapse rate, 79% fewer active MRI lesions, and 73% reduced rescue-therapy use. The FDA action date is January 10, 2027. Enspryng is currently approved in approximately 90 countries for neuromyelitis optica spectrum disorder (NMOSD).
Simcere Zaiming (a subsidiary of China's Simcere Pharmaceutical Group) announced Wednesday September 2, 2026 an exclusive global licensing agreement with Roche for SIM0660, a T-cell engager tri-specific antibody targeting CD79a, CD19, and CD3 for B-cell-mediated diseases. Deal terms: $75 million upfront plus up to $1.53 billion in total development, regulatory, and commercial milestone payments plus tiered royalties up to double-digits on future net sales. Roche acquires exclusive global rights to develop, manufacture, and commercialize SIM0660. The molecule combines a CD3-engaging arm with binding domains targeting the two B-cell antigens CD79a and CD19 to induce T-cell-mediated cytotoxicity while limiting cytokine release, positioned to compete with the emerging poly-specific antibody category (Amgen tarlatamab, Regeneron REGN5459, Janssen amivantamab). The transaction is the latest in a $60+ billion H1 2026 wave of China-to-multinational biotech licensing that continues to feed U.S. and European pharma pipelines.
Roche (SIX: ROG) is scheduled to hold its investor Pharma Day Monday September 28, 2026, providing updates across the R&D portfolio including three obesity assets that collectively position the company as the credible third-place global obesity competitor behind Eli Lilly and Novo Nordisk. Petrelintide (amylin analog, partnered with Zealand Pharma under the March 2025 up-to-$5.3 billion collaboration, Phase 3 monotherapy initiation planned late 2026 following ZUPREME-1's 10.7% weight loss at 42 weeks). Enicepatide (CT-388, dual GLP-1/GIP receptor agonist acquired from Carmot Therapeutics in 2023, 54% obesity resolution at 24 mg in Phase 2). HM17321 (urocortin-2 / CRFR2 receptor agonist peptide licensed from Hanmi Pharm on August 24, 2026 with $190 million upfront plus up to $2.3 billion in milestones plus tiered royalties). The Roche Pharma Day coincides with the EASD 2026 Annual Meeting Milan September 28 through October 2, where AstraZeneca will present AZD6234 Phase 2 data, Zealand Pharma will present petrelintide data, and Novo Nordisk will present amycretin and CagriSema updates.
Roche (SIX: ROG) is scheduled to hold its Pharma Day investor event Monday September 28, 2026, providing updates across the R&D portfolio including three top-three-position obesity assets: petrelintide (amylin analog partnered with Zealand Pharma under the March 2025 up-to-$5.3 billion collaboration, ZUPREME-1 documented 10.7% weight loss at 42 weeks, Phase 3 monotherapy initiation planned late 2026); enicepatide (CT-388, dual GLP-1/GIP receptor agonist acquired from Carmot Therapeutics in 2023, 54% obesity resolution at 24 mg in Phase 2); and HM17321 (urocortin-2 / CRFR2 receptor agonist peptide licensed from Hanmi Pharm on August 24, 2026 with $190 million upfront plus up to $2.3 billion in milestones plus tiered royalties; Genentech takes over from Phase 2 forward). The Pharma Day briefing frames Roche as a credible third-place global obesity competitor behind Eli Lilly (Zepbound-Mounjaro-Foundayo plus upcoming retatrutide) and Novo Nordisk (Wegovy-Ozempic plus CagriSema plus amycretin), with EASD 2026 Milan September 28-October 2 the immediate downstream data catalyst.
DualityBio (HKEX: 9606) announced Friday August 28, 2026 a global collaboration and license agreement with Genentech (Roche Group) to develop next-generation antibody-drug conjugates on DualityBio's proprietary DUPAC (DualityBio Unique Payload Antibody Conjugate) platform. Terms: $45 million upfront to DualityBio plus more than $1 billion in aggregate development, regulatory, and commercial milestone payments across all programs, with tiered royalties on annual net sales. DualityBio handles discovery through Phase Ia; Genentech takes over global clinical development and commercialization. The DUPAC platform is one of DualityBio's four proprietary ADC platforms and is dedicated to payloads with novel mechanisms of action designed to address resistance to existing topoisomerase inhibitor-based ADCs (Trodelvy, Enhertu, Datroway, and successors). The deal is Genentech's second Asia-based ADC alliance in a week and continues the pattern of large pharma buying diverse payload chemistries as ADC-first-line combinations expand.
Follow-through analyst commentary Tuesday August 25, 2026 on the Monday Roche (SIX: ROG) and Hanmi Pharm HM17321 urocortin-2 (UCN2) obesity licensing deal positioned Roche as now targeting a top-three global obesity commercial position behind Eli Lilly (Zepbound, Mounjaro, Foundayo, and upcoming retatrutide) and Novo Nordisk (Wegovy, Ozempic, Wegovy Pill, Wegovy HD, CagriSema under review). Deal recap: $190 million upfront, up to $2.3 billion in milestones, plus tiered royalties; Genentech gets global rights excluding South Korea. HM17321 mechanism: a proprietary urocortin-2 (UCN2) analog peptide that selectively activates the corticotropin-releasing factor 2 receptor (CRFR2), a mechanism distinct from the incretin pathway (GLP-1, GIP) that anchors every currently-approved obesity drug. Roche obesity portfolio positioning: HM17321 combines with Roche's existing CT-388 (a dual GIP/GLP-1 receptor agonist acquired in the December 2023 Carmot Therapeutics acquisition for $2.7 billion, currently in Phase 2 for obesity and type 2 diabetes) and the emerging Roche obesity pipeline including RG7500 orforglipron precursor and other early-stage assets. The multi-mechanism portfolio provides a differentiated commercial positioning to compete across weight-loss efficacy (Roche's incretin agonist candidates match Lilly and Novo) and muscle-preservation (HM17321's differentiated UCN2 mechanism designed for lean mass preservation). Roche's obesity ambition contrasts with prior investor skepticism about its late-cycle entry into the category; Tuesday's analyst commentary suggests the multi-mechanism strategy could position Roche credibly for 2028-2030 commercial launches assuming pipeline programs advance to registration.
Hanmi Pharm (KRX: 128940) signed Monday August 24, 2026 an exclusive licensing agreement with Genentech (a member of the Roche Group) for HM17321, a proprietary urocortin-2 (UCN2) analog peptide for obesity. Deal terms: $190 million upfront payment, up to $2.3 billion in development, regulatory, and commercial milestone payments, plus tiered royalties on sales. Territory: Genentech secures global rights excluding South Korea, where Hanmi retains the license. Mechanism: HM17321 selectively activates the corticotropin-releasing factor 2 receptor (CRFR2), a peptide-hormone receptor pathway distinct from the incretin pathway (GLP-1 receptor, GIP receptor) that anchors every currently-approved obesity drug including semaglutide, tirzepatide, orforglipron, and the broader GLP-1 receptor agonist class. Urocortin-2 is a naturally occurring 38-amino-acid peptide of the corticotropin-releasing factor family. Differentiated profile: HM17321 is positioned as a potential first-in-class treatment designed to simultaneously promote weight loss and preserve lean body mass, an important differentiator against the semaglutide-tirzepatide-retatrutide GLP-1 class where roughly 25% of the total weight lost is lean muscle mass. Development pathway: Hanmi received FDA IND clearance to initiate a Phase 1 clinical trial in November 2025. Hanmi is responsible for completing the Phase 1 clinical trial, after which Genentech will take over development starting with Phase 2 clinical trials. The deal represents one of the largest 2026 obesity licensing transactions and adds a substantially different mechanism to Roche's obesity portfolio that also includes CT-388 (dual GIP/GLP-1 agonist from the Carmot Therapeutics acquisition).
Roche (SIX: ROG) presented new Elecsys plasma phosphorylated-tau 217 (pTau217) blood test performance data at AAIC 2026 in London (July 12-15, 2026) covering both primary care and secondary care settings. The Elecsys pTau217 in vitro diagnostic assay, developed in collaboration with Eli Lilly, received CE Mark certification on May 12, 2026 as an amyloid-pathology rule-in and rule-out test for adults presenting with symptoms of cognitive decline. The same high and low cutoffs of the blood test can be used across primary care (family physicians, general internists) and secondary care (memory clinics, neurology specialty practice) to rule in or rule out amyloid pathology, which simplifies the diagnostic pathway substantially compared with amyloid PET imaging or lumbar puncture. The AAIC 2026 presentations evaluated Elecsys pTau217 performance across both care settings and add real-world diagnostic evidence to the tau-blood-test infrastructure that Eli Lilly's Samantha Burnham anchored earlier in the week with the rule-in-versus-amyloid-PET data set. Roche's AAIC 2026 program spanned undiagnosed Alzheimer's pathology in cardiovascular patients, ApoE4-dependent CETP-inhibitor dose response, and Alzheimer's diagnostic-and-therapeutic integration.
BioPharma Dive's June 8 ADA wrap framed the meeting's competitive sort: Lilly reinforced its lead with retatrutide (28.3%) and Foundayo's head-to-head win over oral semaglutide; Pfizer's berobenatide emerged as 'foundational' with the monthly-dosing differentiation; Roche's enicepatide drew 'me-too' framing from RBC's Trung Huynh ('does little to differentiate enicepatide from its peers'). Novo Nordisk lost ground after CagriSema missed non-inferiority versus its target competitor on some endpoints. Lilly closed about 4.5% higher Monday on the data; Novo fell 3.46%.
Genentech presented Phase 2 CT388-103 data for enicepatide, the once-weekly GLP-1/GIP dual agonist, at the Roche investor event Monday June 8. The 48-week study produced 22.5% placebo-adjusted weight loss in adults with overweight or obesity, with 26% of participants losing more than 30% of body weight and almost 40% reaching at least 25%. Both enicepatide and petrelintide advance into Phase 3, and the planned Phase 2 multi-arm fixed-dose combination of the two starts mid-2026.
Roche presented ZUPREME-1 Phase 2 data for petrelintide, the once-weekly long-acting amylin analog licensed from Zealand Pharma, at the Monday June 8 investor event. The pitch hinges on tolerability: published topline showed up to 10.7% weight loss at 42 weeks versus 1.7% placebo, with discontinuation 4.8% vs 4.9% placebo and no vomiting at the maximally effective dose. Medical Daily framed the readout as a non-incretin option for the estimated 30-40% of patients who quit GLP-1s for GI side effects. Petrelintide advances to Phase 3 alongside enicepatide.
Genentech confirmed at its Monday investor event that the planned Phase 2 multi-arm fixed-dose combination of petrelintide (amylin analog) and enicepatide (GLP-1/GIP) starts mid-2026. The setup mirrors Novo's CagriSema and Lilly's Mounjaro-plus-amylin work, with Roche aiming for the same dual-mechanism economics that produced REIMAGINE 2's head-to-head win this week. Roche projected $9 billion in peak annual sales for the combined obesity pipeline at its Q1 print.
Genentech, Roche's US arm, will present detailed Phase 2 ZUPREME-1 data for the amylin analog petrelintide and Phase 2 CT388-103 data for the GLP-1/GIP agonist enicepatide as late-breakers at ADA 2026, with a June 8 virtual investor event. The Roche obesity package combines the two peptides as a planned fixed-dose Phase 2 combination later this year, and the company has projected $9 billion in peak annual sales for the combined pipeline.
