Heymsfield JAMA 2021: -20.5% fat mass with +3.6% lean mass gain at 48 weeks. Unique profile: most weight-loss drugs (incl. GLP-1s) cost ~25-30% of weight loss as lean mass. Now owned by Lilly — actively being explored as combo with tirzepatide for body recomposition. Highlighted in 2026 obesity-pharmacotherapy reviews …

Stage / status: Investigational; CagriSema combination filed for approval 2025
REDEFINE 1 (Garvey NEJM 2025): CagriSema 2.4mg/2.4mg achieved -20.4% body weight at 68 weeks vs -3.0% placebo (n=3417, no T2D). Notably below the ~25% projected from Phase 2 — Novo stock fell at the December 2024 readout. Cagrilintide alone -11.5%. REDEFINE 2 (T2D, n=1206): -13.7% vs -3.4% placebo at 68 weeks. REDEFINE…

Stage / status: Investigational / compounded (Androxal was not FDA-approved; no FDA-approved US product)
Cleaner pharmacology than mixed clomiphene because it lacks zuclomiphene, the longer-lived estrogenic isomer. Phase 2/3 studies showed testosterone restoration while maintaining sperm counts, unlike testosterone gel. FDA did not approve Androxal after the 2015 review cycle, so US access is compounded or research-market…

Developed by Nippon Shinyaku; acquired by Aevi Medical then Supernus. Phase 2 in adolescents with ADHD and mGluR network mutations showed modest effect; Phase 3 program effectively halted. Popular in nootropic circles; limited tolerance.

Stage / status: Investigational (Phase 3)
Amgen. Phase 2 (Jastreboff NEJM 2025, n=592, NCT05669599): obesity cohort -12.3% to -16.2% body weight at 52 weeks vs -2.5% placebo; T2D cohort -8.4% to -12.3% with HbA1c -1.2 to -1.6 percentage points. Once-monthly dosing is the differentiator vs weekly GLP-1s. Counterintuitive that BOTH GIP agonism (tirzepatide) AND …

Revival of CETP inhibition after the torcetrapib (BP/mortality) and dalcetrapib (futile) failures. Obicetrapib's hydrophilic structure avoids torcetrapib's off-target effects. BROADWAY trial: -32% LDL on top of max statin. Triple combo (obicetrapib + ezetimibe + statin) ranks highest in 2026 network meta for LDL/ApoB r…

Stage / status: Phase 1/2 · Novo Nordisk
Unimolecular GLP-1 / amylin co-agonist in both oral and SC formats. If the early Phase 1 weight-loss signal (~13% in 12 weeks oral, ~24% in 36 weeks SC) holds through Phase 2, it would be the first single-molecule approach matching tirzepatide-class effect sizes with the oral-route advantage.
Next milestone: Phase 2 readout expected 2026 H2 - 2027 H1
incretinamylinoral-glp1
Stage / status: Phase 2 · Eli Lilly
Long-acting amylin analog being developed as monotherapy and as a stack partner for tirzepatide. Amylin alone has been a long-time mechanistic story (pramlintide) without a long-acting product; eloralintide would be the first.
Next milestone: Phase 2 dose-ranging data 2026-2027

Stage / status: Phase 3 (China-approved; West pending) · Innovent / Eli Lilly
GLP-1 / glucagon dual agonist already approved in China (June 2025) on GLORY-1 showing -16.8% at 32 weeks. Western Phase 3 data and FDA filing are the next decision-relevant events. Stronger hepatic-fat-oxidation signal than pure-GLP-1 agents — particularly interesting for MASLD comorbidity.
Next milestone: Western Phase 3 readouts and FDA filing 2026-2027

Stage / status: Phase 3 · Ionis (olezarsen) / Arrowhead (plozasiran)
ApoC-III inhibitors for severe hypertriglyceridemia and FCS (familial chylomicronemia syndrome). Olezarsen FDA-approved for FCS Dec 2024. Watch for indication expansion to severe HTG and cardiovascular outcomes — would broaden into the >500 mg/dL TG population currently served by icosapent ethyl and fenofibrate.
Next milestone: Olezarsen severe HTG indication expansion 2026; plozasiran SHASTA Phase 3 readouts
apoc3rna-therapyhypertriglyceridemia
Stage / status: Approved (HoFH); broader indications pending · Regeneron (evinacumab) / Arrowhead (zodasiran)
ANGPTL3 inhibition lowers LDL, TG, and HDL via a separate pathway from PCSK9. Currently approved only for homozygous FH; broader Phase 3 work in refractory dyslipidemia and severe HTG is the question. RNA-targeted zodasiran would lower the cost of chronic administration vs the antibody form.

Stage / status: Phase 3 (menopause); approved as contraceptive · Mithra / Estetra
Native fetal estrogen with selective ER activation profile and apparently cleaner thrombotic risk than synthetic estrogens. Already approved as the contraceptive Donesta/Estelle. Menopause indication would offer an alternative for women with HRT contraindications (clot risk, family history) without the non-hormonal compromise of NK3 antagonists.
Next milestone: Menopause Phase 3 readout 2026-2027

Stage / status: Phase 3 (China; AGA) · Kintor Pharmaceutical
Topical androgen receptor antagonist for androgenetic alopecia. Mechanism allows scalp-targeted DHT blockade without the systemic sexual side-effect profile of oral finasteride/dutasteride. China Phase 3 ongoing; US Phase 2 mixed but Phase 3 design improvements may rescue.
Next milestone: China Phase 3 readout and US Phase 3 design 2026

Stage / status: Phase 2 (AGA); approved for acne · Cassiopea / Sun Pharma
Topical androgen-receptor antagonist already FDA-approved 2020 for acne. Hair-growth Phase 2 data exist; Phase 3 for AGA would broaden access to a non-systemic anti-androgen for AGA — complementary or competitive with pyrilutamide.

Atypical antipsychotic with serotonin, dopamine, and glutamatergic mechanism; clean metabolic profile. Already approved for bipolar depression. MDD adjunct Phase 3 program is the next expansion — would put a non-SSRI, non-SNRI option into the adjunctive-MDD space dominated by atypicals.
