    Summary Layer

    The second half of September 2026 marks a major Phase 3 expansion for petrelintide, Zealand Pharma’s long-acting amylin analog being co-developed with Roche. Two franchise-scale studies profiled in this edition opened in parallel: obesity/overweight monotherapy (3,900 participants) and obesity/overweight with established cardiovascular disease (2,500 participants). Together, they place 6,400 participants into the late-stage petrelintide program tracked here.

    Three major ADC pivotals plus a PD-1/VEGF bispecific challenge launch in the same window. BMS advances Iza-bren, an EGFR/HER3 bispecific ADC, with osimertinib in first-line EGFR-mutant NSCLC. GSK moves the B7-H3 ADC Ris-Rez into mCRPC, and Merck/Daiichi Sankyo advance the CDH6 ADC R-DXd into ovarian maintenance. In parallel, AbbVie moves ABBV-1480, a PD-1/VEGF bispecific antibody, into a Phase 3 head-to-head against pembrolizumab plus chemotherapy in first-line NSCLC.

    Roche’s divarasib pushes KRAS G12C into curative-intent adjuvant NSCLC. This Phase 3 tests a KRAS G12C inhibitor after surgery in Stage II–III disease, extending the mutation-directed treatment strategy beyond metastatic settings. 15 high-signal trials are profiled across oncology, cardiometabolic disease, immunology/respiratory, and neurology, with cell therapy represented through C-CAR168.

    ▸ Oncology

    Phase 3 · Oncology — first-line EGFR NSCLC · MEGA-SCALE

    Izalontamab Brengitecan (Iza-bren) + Osimertinib vs. Osimertinib ± Chemo in First-Line EGFR-Mutant NSCLC

    Sponsor: Bristol-Myers Squibb (via SystImmune partnership)

    Phase / Status / Enrollment: Phase 3, randomized, open-label · Not yet recruiting · 850 participants · 103 locations

    Timeline: Start September 30, 2026 · Primary completion December 2031

    Mechanism: Izalontamab Brengitecan (BMS-986507, “Iza-bren”) is the branded form of BL-B01D1, SystImmune’s EGFR/HER3 bispecific antibody-drug conjugate. Bristol Myers Squibb and SystImmune announced their global collaboration in December 2023, with $800 million upfront and total potential consideration of up to $8.4 billion. The Phase 3 study combines Iza-bren with osimertinib in previously untreated EGFR-mutant NSCLC.

    Why it matters: This is a flagship pivotal from one of the largest China-to-global ADC licensing collaborations of its period. A positive result would establish the Iza-bren plus osimertinib combination as a direct first-line challenger in EGFR-mutant NSCLC and materially validate the BMS–SystImmune partnership at Phase 3 scale.

    Phase 3 · Oncology — first-line NSCLC · MEGA-SCALE

    ABBV-1480 + Chemotherapy vs. Pembrolizumab + Chemotherapy in First-Line Locally Advanced/Metastatic NSCLC

    Sponsor: AbbVie

    Phase / Status / Enrollment: Phase 3, randomized, open-label, multiregional · Not yet recruiting · 940 participants

    Timeline: Start September 22, 2026 · Primary completion December 2029

    Mechanism: ABBV-1480 (RC148) is a humanized PD-1/VEGF bispecific antibody licensed by AbbVie from RemeGen outside Greater China. It combines PD-1 checkpoint inhibition with VEGF pathway blockade in a single molecule and is being tested with platinum chemotherapy against pembrolizumab plus chemotherapy.

    Why it matters: This is a direct Phase 3 challenge to the pembrolizumab plus chemotherapy backbone in first-line advanced NSCLC. If ABBV-1480 improves outcomes, AbbVie would add a late-stage PD-1/VEGF bispecific to a treatment setting currently anchored by established checkpoint inhibitor combinations.

    Phase 3 · Oncology — mCRPC · B7-H3 ADC · MEGA-SCALE

    EMBOLD Prostate-302 · Risvutatug Rezetecan (B7-H3 ADC) vs. Enzalutamide/Abiraterone in mCRPC

    Sponsor: GlaxoSmithKline

    Phase / Status / Enrollment: Phase 3, randomized · Recruiting · 684 participants

    Timeline: Start September 22, 2026 · Primary completion December 2029

    Mechanism: Risvutatug Rezetecan (Ris-Rez) is GSK's B7-H3-directed antibody-drug conjugate. Tested in metastatic castration-resistant prostate cancer vs. investigator's choice of second ARPI (enzalutamide or abiraterone + prednisone).

    Why it matters: B7-H3 is an increasingly important ADC target across solid tumors. Ris-Rez brings GSK into the late-stage B7-H3 field in mCRPC, alongside other advanced programs such as Merck/Daiichi Sankyo’s ifinatamab deruxtecan. A positive Phase 3 result would strengthen B7-H3 as a clinically validated ADC target in prostate cancer.

    Phase 3 · Oncology — ovarian maintenance · CDH6 ADC · MEGA-SCALE

    REJOICE-Ovarian 04 · Raludotatug Deruxtecan (R-DXd) ± Bevacizumab vs. SoC in Non-HRD+ Ovarian Cancer Maintenance

    Sponsor: Merck Sharp & Dohme LLC

    Phase / Status / Enrollment: Phase 3, randomized, open-label · Recruiting · 802 participants

    Timeline: Start September 18, 2026 · Primary completion March 2032

    Mechanism: Raludotatug deruxtecan (R-DXd, MK-5909) is Merck's CDH6 (cadherin-6)-directed ADC with a topoisomerase I deruxtecan payload — from the Merck-Daiichi Sankyo collaboration. Tested as maintenance ± bevacizumab in newly diagnosed advanced non-HRD-positive ovarian cancer after first-line platinum chemotherapy.

    Why it matters: The non-HRD-positive ovarian cancer population (roughly half of all ovarian patients) has limited maintenance options beyond bevacizumab. PARP inhibitors work best in HRD+ tumors. R-DXd targets CDH6, expressed on ovarian and renal cancers — validated in early trials with response rates ~50% in heavily pretreated ovarian cancer. First-line maintenance Phase 3 is Merck's franchise-scale bet on CDH6 as the next validated ADC target.

    Phase 3 · Oncology — adjuvant KRAS G12C+ NSCLC

    Divarasib vs. Investigator's Choice of Immunotherapy or Observation in Resected Stage II-III KRAS G12C+ NSCLC

    Sponsor: Hoffmann-La Roche

    Phase / Status / Enrollment: Phase 3, randomized, open-label · Recruiting · 400 participants · 19 sites

    Timeline: Start September 30, 2026 · Primary completion January 2032

    Mechanism: Divarasib (GDC-6036) is Roche/Genentech's next-generation covalent KRAS G12C inhibitor. Tested in patients with resected Stage II-III KRAS G12C-positive NSCLC vs. investigator's choice of adjuvant immunotherapy (pembrolizumab or nivolumab) or observation.

    Why it matters: This is a Phase 3 test of KRAS G12C inhibition in the adjuvant NSCLC setting. The strategy follows the broader movement of genotype-directed lung cancer therapy from advanced disease toward curative-intent treatment. A positive readout could expand KRAS G12C testing and targeted treatment into resected disease.

    ▸ Cardiometabolic

    Phase 3 · Cardiometabolic — obesity flagship · MEGA-SCALE

    Once-Weekly Petrelintide vs. Placebo in Adults With Overweight or Obesity

    Sponsor: Hoffmann-La Roche

    Phase / Status / Enrollment: Phase 3, randomized, double-blind, placebo-controlled · Not yet recruiting · 3,900 participants

    Timeline: Start September 30, 2026 · Primary completion December 2028

    Mechanism: Petrelintide is Zealand Pharma’s long-acting amylin analog, being co-developed and co-commercialized with Roche under a global collaboration and licensing agreement announced in March 2025. This study evaluates once-weekly petrelintide monotherapy for chronic weight management in adults with overweight or obesity.

    Why it matters: Petrelintide gives Roche and Zealand Pharma a differentiated amylin-based entry into a market dominated by incretin therapies. The 3,900-participant Phase 3 tests whether a once-weekly amylin analog can deliver clinically meaningful weight loss with a distinct tolerability and mechanism profile at registrational scale.

    Phase 3 · Cardiometabolic — obesity + CV disease · MEGA-SCALE

    Once-Weekly Petrelintide vs. Placebo in Overweight/Obesity With Established Cardiovascular Disease

    Sponsor: Hoffmann-La Roche

    Phase / Status / Enrollment: Phase 3, randomized, double-blind, placebo-controlled · Not yet recruiting · 2,500 participants

    Timeline: Start September 30, 2026 · Primary completion July 2030

    Mechanism: This companion Phase 3 evaluates petrelintide versus placebo for weight management in adults with overweight or obesity who also have established cardiovascular disease. The registered primary endpoint is percentage change in body weight, making this a weight-management study in a high-risk CVD population rather than a dedicated cardiovascular outcomes trial.

    Why it matters: Studying petrelintide in participants with established cardiovascular disease tests the asset in a clinically high-risk population that is especially relevant to obesity treatment. Importantly, the registered study is not a MACE-driven cardiovascular outcomes trial; its primary efficacy focus is weight change.

    Phase 3 · Cardiometabolic — obesity (Novo head-to-head vs. semaglutide)

    AMAZE 7 · Zenagamtide vs. Semaglutide in Overweight or Obesity

    Sponsor: Novo Nordisk A/S

    Phase / Status / Enrollment: Phase 3, randomized, double-blind · Recruiting · 650 participants · 43 locations

    Timeline: Start September 22, 2026 · Primary completion October 2028

    Mechanism: Zenagamtide, also known as amycretin, is Novo Nordisk’s investigational unimolecular GLP-1 and amylin receptor agonist. AMAZE 7 tests once-weekly zenagamtide head-to-head against semaglutide in adults with overweight or obesity.

    Why it matters: Novo Nordisk is testing a next-generation dual GLP-1/amylin mechanism directly against semaglutide, its current obesity standard. The head-to-head design makes AMAZE 7 an important internal benchmark for whether zenagamtide can support franchise succession beyond semaglutide.

    Sponsor: The United Bio-Technology (Hengqin) Co., Ltd.

    Phase / Status / Enrollment: Phase 3, randomized, double-blind, placebo-controlled · Not yet recruiting · 150 participants

    Timeline: Start September 18, 2026 · Primary completion September 2028

    Mechanism: UBT251 is UBT's GLP-1/glucagon/GIP triple agonist. UNISHAPE-OSA-1 extends the program into obesity + moderate-to-severe OSA in patients not on positive airway pressure therapy — following Lilly's tirzepatide OSA precedent (SURMOUNT-OSA).

    Why it matters: UBT251 is expanding rapidly across multiple Phase 3 metabolic indications. UNISHAPE-OSA-1 extends the program into obesity with moderate-to-severe obstructive sleep apnea, a strategically important obesity-comorbidity setting following the clinical validation of incretin-based weight loss in OSA.

    Phase 3 · Cardiometabolic — uncontrolled hypertension (China)

    Baxdrostat 2mg vs. Placebo in Chinese Participants With Uncontrolled Hypertension on ≥2 Antihypertensives

    Sponsor: AstraZeneca

    Phase / Status / Enrollment: Phase 3, randomized, double-blind, placebo-controlled · Not yet recruiting · 286 participants

    Timeline: Start September 30, 2026 · Primary completion February 2028

    Mechanism: Baxdrostat is AZ's aldosterone synthase (CYP11B2) inhibitor — inherited via the 2023 CinCor Pharma acquisition ($1.8B). This is the China-specific Phase 3 for the uncontrolled hypertension indication on top of 2+ antihypertensives excluding diuretics.

    Why it matters: Baxdrostat is one of the highest-value CV assets in the AZ pipeline post-CinCor deal. This Chinese Ph3 opens China as a global regulatory pathway alongside AZ's US/EU pivotal programs. Uncontrolled hypertension is the largest addressable cardiometabolic market by patient count — a definitive aldosterone-synthase inhibitor readout has franchise-shifting potential.

    Phase 2 · Immunology — dual CD20/BCMA CAR-T (lupus nephritis)

    C-CAR168 · Autologous Dual Anti-CD20/BCMA CAR-T in Refractory Lupus Nephritis

    Sponsor: AbelZeta Inc.

    Phase / Status / Enrollment: Phase 2, single-arm · Not yet recruiting · 50 participants

    Timeline: Start September 30, 2026 · Primary completion December 2028

    Mechanism: C-CAR168 is AbelZeta's autologous dual-antigen CAR-T therapy targeting both CD20 (mature B cells) and BCMA (plasma cells). Tested in lupus nephritis refractory to standard therapy.

    Why it matters: Fourth autoimmune CAR-T program in four editions (Myeloid Tx CRT-402 in vivo CAR-T Ed 16, CRISPR Therapeutics CTX112 allo Ed 17, now C-CAR168 dual autologous). Dual CD20/BCMA CAR-T is a mechanistic evolution — targeting both mature B cells AND plasma cells addresses the residual autoantibody-producing cell reservoir that CD19-only CAR-T can miss. First dual-target autoimmune CAR-T Phase 2 in lupus.

    Tilrekimig Long-Term Safety and Efficacy Extension in Moderate-to-Severe COPD

    Sponsor: Pfizer

    Phase / Status / Enrollment: Phase 3, open-label extension · Not yet recruiting · 1,360 participants

    Timeline: Start September 21, 2026 · Primary completion May 2034

    Mechanism: This is a long-term open-label extension of Pfizer’s tilrekimig in moderate-to-severe COPD. Tilrekimig is also being developed across other Type 2 inflammatory diseases, including asthma and atopic dermatitis, creating a broader multi-indication Phase 3 program.

    Why it matters: Second respiratory OLE in two editions (following Sanofi's lunsekimig COPD OLE, Ed 17). Pfizer and Sanofi are building parallel long-term safety databases at 1,360-pt and 1,508-pt scale, respectively, for their competing Type 2 respiratory franchises. Long-term safety data is what determines commercial success in a chronic maintenance category with 20-year use horizons.

    Timeline: Start September 23, 2026 · Primary completion July 14, 2027

    Mechanism: NVG-291 is NervGen's protein tyrosine phosphatase sigma (PTPσ) modulator — a peptide designed to promote axonal regeneration and neural plasticity in chronic spinal cord injury. Tested vs. placebo in adults with chronic SCI.

    Why it matters: RESTORE brings a novel neural-repair mechanism into Phase 3 for chronic spinal cord injury, an area with no approved neuroregenerative therapy. A positive result would provide pivotal evidence for PTPσ modulation as a therapeutic strategy in chronic CNS injury.

    Signal Convergence

    Five patterns across the September 16–30 window

    1. Petrelintide scales into franchise-sized Phase 3 development. The two Roche-sponsored petrelintide studies profiled in this edition total 6,400 participants across general obesity/overweight and established cardiovascular disease populations. The program is based on Zealand Pharma’s amylin analog under the Roche–Zealand global co-development and co-commercialization collaboration.

    2. Three ADC pivotals and a PD-1/VEGF bispecific move in parallel. BMS advances Iza-bren, GSK advances Ris-Rez, and Merck/Daiichi Sankyo advance R-DXd across lung, prostate, and ovarian cancer. AbbVie adds a separate first-line NSCLC challenge with the PD-1/VEGF bispecific ABBV-1480.

    3. Mutation-directed therapy crosses into curative-intent adjuvant. Roche's Divarasib Phase 3 in resected KRAS G12C+ Stage II-III NSCLC is the first adjuvant KRAS G12C inhibitor pivotal. Follows the EGFR playbook (osimertinib ADAURA) and ALK playbook (alectinib ALINA) — mutation-directed therapy now spans the entire disease continuum from metastatic to resectable.

    4. Metabolic Phase 3 programs are expanding into comorbidity-specific and head-to-head settings. UBT251 UNISHAPE-OSA-1 tests a triple agonist in obesity with moderate-to-severe OSA, while AMAZE 7 puts Novo Nordisk’s zenagamtide directly against semaglutide. In parallel, petrelintide is being tested in people with established cardiovascular disease, broadening late-stage metabolic competition beyond weight loss alone.

    5. Autoimmune CAR-T is moving toward mechanistic diversification. AbelZeta’s C-CAR168 targets both CD20 and BCMA in refractory lupus nephritis, extending the autoimmune CAR-T sequence tracked in recent Trial Watch editions toward dual-antigen strategies.

    Underlying truth: late-stage competition is intensifying simultaneously in metabolic disease and precision oncology. This window combines franchise-scale obesity studies, multiple ADC pivotals, a PD-1/VEGF bispecific head-to-head, autoimmune CAR-T, and late-stage neurology programs.
