Balancing ethical norms and duties for the introduction of new medicines through conditional marketing authorization: a research agenda.

The European Medicines Agency's conditional marketing authorization (CMA) aims to expedite patient access to medicines for unmet medical needs by shifting a part of the drug development process post-authorization. We highlight ethical issues surrounding CMA, comprising (i) the complexity of defining unmet medical need; (ii) poor understanding of CMA and its impact on informed consent; (iii) hope versus unrealistic optimism; (iv) implications of prolonged post-authorization studies and potential patient harm; (v) rights and duties of patients surrounding participation in post-authorization studies; (vi) access to previously authorized CMA medicines; and (vii) the "benefit slippage" phenomenon, defined as the gradual shift of strict criteria to less strict criteria. We propose a comprehensive research agenda to address these ethical issues, and stress the need for multi-stakeholder engagement to ensure patient-centered use of CMA.

The Development of High-Quality Multispecies Probiotic Formulations: From Bench to Market.

Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. To date, there is an increasing number of commercially available products containing probiotics on the market. Probiotics have been recommended by health care professionals for reasons ranging from their long-term immunomodulatory effects to proven benefits in the management of different health conditions.

Combination therapy with bortezomib, continuous low-dose cyclophosphamide and dexamethasone followed by one year of maintenance treatment for relapsed multiple myeloma patients.

Combination therapy for longer periods but at low dose might be an effective and tolerable manner to treat patients with relapsed multiple myeloma (MM). We used bortezomib, dexamethasone and low-dose oral cyclophosphamide as an induction regimen, followed by 1 year of maintenance consisting of bortezomib and cyclophosphamide. Relapsed MM patients were treated with six cycles of bortezomib twice weekly, cyclophosphamide 50 mg daily and dexamethasone.
