Daratumumab and hyaluronidase-fihj was non-inferior to daratumumab IV in evaluating these two endpoints.Efficacy of daratumumab and hyaluronidase-fihj in combination with VMP (D-VMP) was evaluated in a single-arm cohort of the PLEIADES trial (NCT03412565), a multi-cohort, open‑label trial. Eligible participants were required to have newly diagnosed multiple myeloma and were ineligible for transplant.Efficacy of daratumumab and hyaluronidase-fihj in combination with Rd (D-Rd) was evaluated in a single-arm cohort of this trial. Eligible participants had received at least one prior line of therapy. Efficacy of daratumumab/hyaluronidase in combination with bortezomib, cyclophosphamide, and dexamethasone was evaluated in ANDROMEDA (NCT03201965), an open-label, randomized, active-controlled trial in 388 participants with newly diagnosed amyloid light-chain amyloidosis with measurable disease and at least one affected organ according to consensus criteria. Participants were randomized to receive bortezomib, cyclophosphamide, and dexamethasone (VCd arm) or with daratumumab and hyaluronidase (D-VCd arm).Efficacy of daratumumab/hyaluronidase in combination with carfilzomib and dexamethasone was evaluated in PLEIADES (NCT03412565), a multi-cohort, open-label trial.

Pharmacology
Systemic absorption of the globular tetradecapeptide is minimal.Linaclotide, like the endogenous guanylin and uroguanylin it mimics, is an agonist that activates the cell surface receptor of guanylate cyclase 2C (GC-C). The medication binds to the surface of the intestinal epithelial cells. Linaclotide is minimally absorbed and it is undetectable in the systemic circulation at therapeutic doses. Activation of GC-C increases cyclic guanosine monophosphate (cGMP). Elevated cGMP stimulates secretion of chloride and bicarbonate and water into the intestinal lumen, mainly by way of cystic fibrosis transmembrane conductance regulator (CFTR) ion channel activation. This results in increased intestinal fluid and accelerated transit. By elevating cGMP, linaclotide is also considered to reduce activation of colonic sensory neurons, reducing pain; and activates colonic motor neurons, which increases smooth muscle contraction and thus promotes bowel movements. Chemistry
Linaclotide is a hybrid peptide design of the E.coli heat-stable enterotoxin (STa) and the endogenous peptide hormones endogenous guanylin and uroguanylin.
