CJC-1295 No Dac: Safety Profile & Research Summary
Resumo da Pesquisa
Clinical & Preclinical Data Status
De acordo com a comprehensive FDA evaluation prepared para o(a) Pharmacy Compounding Advisory Committee (December 2024), there are no published human ensaios clinicos and no preclinical efficacy or toxicity studies specifically for CJC-1295 sem DAC (Modified GRF 1-29). All prominent ensaios clinicos associado(a) com the name "CJC-1295" in medical literature were conducted using the DAC variant, que is pharmacokinetically distinct due to its albumin-binding Drug Affinity Complex.[9][10]
Key Studies on CJC-1295 (DAC Variant) — Often Misatribuido(a) a No-DAC
| Estudo | Modelo | Principais Achados | Ref |
|---|---|---|---|
| Teichman et al. (2006) J Clin Endocrinol Metab | Healthy human adults; 30–250 mcg/kg SC; single or weekly/biweekly doses | Dose-dependent aumenta in mean plasma GH (2–10-fold for ≥6 days) and IGF-1 (1.5–3-fold for 9–11 days). Half-life 5.8–8.1 days. Note: DAC variant, not applicable to no-DAC. | [8] |
| Ionescu & Frohman (2006) J Clin Endocrinol Metab | Healthy human adults; CJC-1295 with DAC | Confirmed que pulsatile GH secretion persists during continuous estimulacao by CJC-1295 (DAC). Note: DAC variant. | [15] |
| Jetté et al. (2005) Endocrinology | Sprague-Dawley rats; 1 µmol/kg SC | Described synthesis of tetrasubstituted GHRH core and DAC conjugation. Demonstrated GH elevation with meia-vida >72 hours. Note: DAC variant. | [4] |
| Alba et al. (2006) Am J Physiol | GHRH camundongos knockout; 2 µg/mouse daily | Normalized growth; aumentou body length and lean mass; aumentou pituitary GH mRNA and somatotroph proliferacao. Note: DAC variant. | [8] |
| Ben-Shlomo et al. (2020) J Clin Invest | C57BL/6 mice and primary pituitary cultures; 10–50 ng/mL in vitro | Intense cAMP estimulacao induziu DNA damage in somatotrophs (H2AX fosforilacao, comet assays). Increased GH levels and pituitary weight in vivo. Note: Likely DAC variant per FDA assessment. | [14] |

| Regulatory Classification | Categoria 2. Significant safety risks or insufficient evidence; restricted from pharmacy manipulacao.[9][10] |
Dosage Overview (From Literature & Clinical Practice)
| Setting | Dose | Route / Schedule | Notes |
|---|---|---|---|
| In Vitro (pituitary cultures) | 10–50 ng/mL | Cell culture | Ben-Shlomo et al. (2020); likely DAC variant[14] |
| Animal (rats — DAC variant) | 1 µmol/kg SC | Subcutaneous injection | Jetté et al. (2005)[4] |
| Animal (mice — DAC variant) | 2 µg/mouse daily | Subcutaneous injection | Alba et al. (2006)[8] |
| Human (DAC variant) | 30–250 mcg/kg | SC; single or weekly/biweekly | Teichman et al. (2006)[8] |
| Human (no-DAC; clinical practice) | 100–300 mcg | SC; 1–3x daily or 5 days/week | Anecdotal protocols; not derivado(a) de ensaios clinicos |
Safety Considerations
| Parametro | Finding |
|---|---|
| Clinical Safety Data | No submitted or identificado(a) clinical safety studies for CJC-1295 (free base) or acetate[9] |
| Preclinical Toxicity Data | No nonclinical toxicity studies (acute, repeat-dose, genotoxicity) identificado(a)[9] |
| Immunogenicity | Theoretical risk of antibody formation; 86% homology with endogenous GHRH[9] |
| Reported Adverse Effects (Anecdotal) | Injection site reactions, flushing, headache, transient hipotensao, water retention[12] |
| Contraindications (General GHRH Analog) | Active malignancy (GH/IGF-1 may promote tumor growth), pregnancy/breastfeeding, hypersensitivity[7] |
| DAC Variant Safety Note | CJC-1295 with DAC was discontinued during Phase 2 trials after a subject death (atribuido(a) a underlying coronary artery disease, not the drug); no such event linked para o(a) no-DAC variant[7] |
