Travoprost/timolol.

Travoprost 0.004%/timolol 0.5% fixed combination (travoprost/timolol) is a once-daily eyedrops solution comprising the prostaglandin F(2alpha) analogue travoprost and the beta-adrenoceptor antagonist timolol. It is indicated for the treatment of patients with open-angle glaucoma or ocular hypertension who are insufficiently responsive to topical beta-adrenoceptor antagonists or prostaglandin analogues. Once-daily travoprost/timolol had generally similar efficacy to travoprost plus timolol and was more effective than travoprost or timolol monotherapy in reducing intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension in randomised, well designed studies. Both travoprost/timolol and latanoprost plus timolol maintained IOP control, and travoprost/timolol was shown to be noninferior to latanoprost/timolol in randomised, well designed studies. Travoprost/timolol was generally well tolerated, with a tolerability profile similar to those of travoprost plus timolol, travoprost or timolol monotherapy and latanoprost plus timolol. The majority of adverse events, such as ocular hyperaemia, were mild and resolved with or without treatment.

Panitumumab: in the treatment of metastatic colorectal cancer.

Panitumumab is a fully human immunoglobulin G2 monoclonal antibody highly selective for the epidermal growth factor receptor (EGFR), which is overexpressed in 25-77% of colorectal cancers. This overexpression is frequently associated with a poor prognosis. In a large, randomised, nonblind, multicentre phase III study in pretreated adult patients with metastatic colorectal cancer and EGFR staining in >or=1% tumour cells, panitumumab 6 mg/kg every 2 weeks plus best supportive care (BSC) was significantly (p < 0.0001) more effective in improving progression-free survival than BSC alone; recipients of panitumumab plus BSC had a 46% lower disease progression rate than those receiving BSC alone after a median follow-up of 19 weeks. Panitumumab 6 mg/kg every 2 weeks or 2.5 mg/kg/week, administered as monotherapy, produced partial response rates of 8-13% and stable disease rates of 21-30% in pretreated patients with metastatic colorectal cancer in three noncomparative, multicentre phase II studies. Preliminary phase II results also suggest a potential role for panitumumab as first-line therapy in combination with fluorouracil, folinic acid and irinotecan in patients with metastatic colorectal cancer. Panitumumab was generally well tolerated. Grade 3/4 skin-related toxicities were reported in 14% of patients receiving panitumumab plus BSC in the phase III study (versus 0% of patients receiving BSC alone). An analysis of pooled data found that high-affinity binding antibodies to panitumumab were detected in <1% of patients.
