Key Preclinical Studies
| Estudo | Modelo | Principais Achados | Ref |
|---|---|---|---|
| Mills et al. (2025) | C57BL/6J mice — Kp-54 | 12.8–50 nM: dose-dependente LH to 3.6 ng/mL at 25 min (p < 0.001); GnRH neurons ativou in olfactory bulb → novel extra-hypothalamic pathway | [19] |
| Izarraras et al. (2025) | DIAMOND mice — TAK-448 MASLD | 0.3 nmol/h × 6 weeks: reduziu liver triglycerides, serum FFA, ALT (p < 0.05); downregulou CIDEA via AMPK-SREBP-1c | [18] |
| Seminara/Ramaswamy (2006/07) | Juvenile rhesus monkeys — IV KP-10 | 200–400 µg/h × 98h: maximal LH at 3h, dessensibilizacao by 12h; GnRH bolus still eficaz but KP-10 bolus was not | [23] |
| Terse et al. (2021) | Dogs — KP-10 1000 µg/kg × 14d | NOAEL at 1000 µg/kg; peak LH at 5 min; no toxicity signs | [24] |
| Thompson et al. (2006) | Adult male rats — cronico(a) KP-54 | Chronic exposure → testicular degeneration; HPG axis supressao via receptor dessensibilizacao | [25] |
| Dinh et al. (2023) | Wistar rats — KP-13 CKD model | 10-day study: aumentou BP, exacerbated CKD markers and uremic cardiomiopatia | [26] |
Human Clinical Data (>1,000 Participants)
| Ensaio | Population | Key Results | Ref |
|---|---|---|---|
| Dhillo et al. (2005) | n=6 healthy men | LH endpoints; first-in-human | [5] |
| Dhillo et al. (2007) | n=8 healthy women | LH endpoints across cycle phases | [6] |
| Abbara et al. (2015) | n=60 IVF, alto(a) OHSS risk | Oocyte-maturation, pregnancy, live-birth and OHSS endpoints | [10] |
| Abbara et al. (2017) | n=62 IVF RCT | Live-birth and OHSS endpoints | [11] |
| Jayasena et al. (2009) | n=10 women with HA | Acute and repeated-exposure LH endpoints | [12] |
| Jayasena et al. (2010) | n=20 women with HA | LH endpoints over 8 weeks | [13] |
| Abbara et al. (2020) | n=21 (HV, HA, PCOS) | MVT-602 vs Kp-54 LH-profile endpoints | [9] |
| Mills et al. (2025) | n=34 (men, women, HA) | LH endpoints | [19] |
| Izzi-Engbeaya et al. (2018) | n=15 healthy men | Glucose-stimulated insulin-secretion endpoint | [22] |
| Comninos et al. (2022) | n=26 healthy men | Osteocalcin endpoint | [21] |
Safety Summary: >1,000 Human Exposures
| Parametro | Finding |
|---|---|
| Cardiotoxicity | None — no changes in HR, BP, or ECG |
| Tachyphylaxis | Continuous high-dose → β-arrestin recruitment → receptor internalizacao → HPG supressao (physiological, not toxic) |
| Dog NOAEL | 1000 µg/kg × 14 days — no toxicity |
| Metabolism | Cleaved by MMP-2, MMP-9, furin; C-terminal cleavage inativa |
