Pathological complete response (pCR) was observed in 118 participants (45.4%) on the trastuzumab/hyaluronidase arm and in 107 participants (40.7%) receiving intravenous trastuzumab (95% CI for difference in pCR: -4.0; 13.4).SafeHER was a prospective, two-cohort, non-randomized, multinational, open-label trial assessing the overall safety and tolerability of trastuzumab/hyaluronidase with chemotherapy in 1,864 participants with HER2-positive breast cancer. Participants received a fixed dose of 600 mg trastuzumab/hyaluronidase every 3 weeks for 18 cycles. trastuzumab/hyaluronidase was initiated either sequentially with chemotherapy, concurrently with chemotherapy, or without adjuvant chemotherapy, or in combination with neoadjuvant chemotherapy followed by trastuzumab.

Pigment dispersion syndrome (PDS) is an  eye disorder that can lead to a form of glaucoma known as pigmentary glaucoma. It takes place when pigment cells slough off from the back of the iris and float around in the aqueous humor. Over time, these pigment cells can accumulate in the anterior chamber in such a way that they begin to clog the trabecular meshwork (the major site of aqueous humour drainage), which can in turn prevent the aqueous humour from draining and therefore increases the pressure inside the eye. A common finding in PDS are central, vertical corneal endothelial pigment deposits, known as Krukenberg spindle. With PDS, the intraocular pressure tends to spike at times and then can return to normal. Exercise has been shown to contribute to spikes in pressure as well. When the pressure is great enough to cause damage to the optic nerve, this is called pigmentary glaucoma. As with all types of glaucoma, when damage happens to the optic nerve fibers, the vision loss that occurs is irreversible and painless. Risk factors
This condition is rare, but occurs most often in Caucasians, particularly men, and the age of onset is relatively low: mid 20s to 40s. As the crystalline lens hardens with age, the lens zonules pull away from the iris and the syndrome lessens and stops. The main risk factor is nearsightedness. Genetic factors may also play a part in the transition from syndrome to the glaucoma condition.
