Zusammenfassung. Theoretischer Hintergrund: In der Methodologie der klinisch-psychologischen Forschung steht nach dem Konzept der evidenzbasierten Psychotherapie das aus der pharmakologischen Forschung und evidenzbasierten Medizin adaptierte 4-Phasen-Prüfmodell im Vordergrund. Empirisch fundierte Psychotherapie ist die Basis von Therapie-Ressourcen wie Behandlungs-Leitlinien und -Manualen sowie Patientenratgebern. Fragestellung: Auf welchen der Prüfphasen liegen die Schwerpunkte der klinisch-psychologischen Forschung, wie viele Therapie-Ressourcen sind aus ihr resultiert, zeigen sich seit 1977 Veränderungen in den Schwerpunkten? Methode: Alle in der Fachliteraturdatenbank PSYNDEX dokumentierten Beiträge zur klinisch-psychologischen Interventionsforschung wurden nach einem erweiterten 4-Phasen-Prüfmodell und nach der Art der Therapie-Ressourcen klassifiziert. Ergebnisse: Zwischen 1977 und 2006 wurden im deutschsprachigen Bereich 16.467 empirische Beiträge zu klinisch-psychologischen Interventionen publiziert. Die Mehrheit ist den Phasen 0 (Entwicklungsphase: 55%), 1 (Erkundungsphase: 23%), 4 (Praxiskontrolle: 12%) und 5 (Prävention, Rehabilitation und Persönlichkeitsentwicklung: 22%) zugeordnet. Befunde zur Phase 2 (Randomisierte Studien: 2.2%) und Phase 3 [Testphase mit Multicenter-Studien (1.5%) und Metaanalysen (1.0%)] wurden seltener publiziert, weisen aber in den letzten zehn Jahren eine ansteigende Tendenz auf. Bei den Therapie-Ressourcen dominieren Patientenratgeber (61%) im Vergleich zu Behandlungs-Manualen (32%) und -Leitlinien (9%). Schlussfolgerungen: Aus der klinisch-psychologischen Forschung im deutschsprachigen Bereich liegt ein umfangreiches Reservoir von Publikationen zur empirisch fundierten Psychotherapie und zu Therapie-Ressourcen vor. Defizite bestehen bei Veröffentlichungen zu randomisierten Studien (Phasen 2 und 3), für die Ratgeber-Literatur ist inzwischen ein Überhang festzustellen.

Drug development is the entire process of introducing a new drug to the market. It involves drug discovery, screening, preclinical testing, an Investigational New Drug (IND) application in the US or a Clinical Trial Application (CTA) in the EU, phase 1–3 clinical trials, a New Drug Application (NDA), Food and Drug Administration (FDA) review and approval, and postapproval studies required for continuing safety evaluation. Preclinical testing assesses safety and biologic activity, phase 1 determines safety and dosage, phase 2 evaluates efficacy and side effects, and phase 3 confirms efficacy and monitors adverse effects in a larger number of patients. Postapproval studies provide additional postmarketing data. On average, it takes 15 years from preclinical studies to regulatory approval by the FDA: about 3.5–6.5 years for preclinical, 1–1.5 years for phase 1, 2 years for phase 2, 3–3.5 years for phase 3, and 1.5–2.5 years for filing the NDA and completing the FDA review process. Of approximately 5000 compounds evaluated in preclinical studies, about 5 compounds enter clinical trials, and 1 compound is approved (Tufts Center for the Study of Drug Development, 2011). Most drug development programs include approximately 35–40 phase 1 studies, 15 phase 2 studies, and 3–5 pivotal trials with more than 5000 patients enrolled. Thus, to produce safe and effective drugs in a regulated environment is a highly complex process. Against this backdrop, what is the best way to develop drugs for pulmonary arterial hypertension (PAH), an orphan disease often rapidly fatal within several years of diagnosis and in which spontaneous regression does not occur?

Meta Analyses

Tenecteplase is a fibrinolytic drug with higher fibrin specificity and longer half-life than the standard stroke thrombolytic, alteplase, permitting the convenience of single bolus administration. Tenecteplase, at 0.5 mg/kg, has regulatory approval to treat ST-segment–elevation myocardial infarction, for which it has equivalent 30-day mortality and fewer systemic hemorrhages. Investigated as a thrombolytic for ischemic stroke over the past 15 years, tenecteplase is currently being studied in several phase 3 trials. Based on a systematic literature search, we provide a qualitative synthesis of published stroke clinical trials of tenecteplase that (1) performed randomized comparisons with alteplase, (2) compared different doses of tenecteplase, or (3) provided unique quantitative meta-analyses. Four phase 2 and one phase 3 study performed randomized comparisons with alteplase. These and other phase 2 studies compared different tenecteplase doses and effects on early outcomes of recanalization, reperfusion, and substantial neurological improvement, as well as symptomatic intracranial hemorrhage and 3-month disability on the modified Rankin Scale. Although no single trial prospectively demonstrated superiority or noninferiority of tenecteplase on clinical outcome, meta-analyses of these trials (1585 patients randomized) point to tenecteplase superiority in recanalization of large vessel occlusions and noninferiority in disability-free 3-month outcome, without increases in symptomatic intracranial hemorrhage or mortality. Doses of 0.25 and 0.4 mg/kg have been tested, but no advantage of the higher dose has been suggested by the results. Current clinical practice guidelines for stroke include intravenous tenecteplase at either dose as a second-tier option, with the 0.25 mg/kg dose recommended for large vessel occlusions, based on a phase 2 trial that demonstrated superior recanalization and improved 3-month outcome relative to alteplase. Ongoing randomized phase 3 trials may better define the comparative risks and benefits of tenecteplase and alteplase for stroke thrombolysis and answer questions of tenecteplase efficacy in the >4.5-hour time window, in wake-up stroke, and in combination with endovascular thrombectomy.

Abstract The objective of this study was to evaluate the effects of dietary supplementation of coated omega-3 fatty acid (n-3 CFA) by corn cob power silica on performance of weaning pigs. A total of 200 weaned pigs [(Landrace x Yorkshire) x Duroc, average initial body weight at 6.97 ± 1.22 kg] were randomly assigned to four experimental treatments in a 6-week experiment in 3 phases as follows: CON, basal diet; 2) 0.3CFA, CON + phase 1(0.3% n-3CFA), phase 2(0.2% n-3CFA), phase 3(0.1% n-3CFA); 3) 0.6CFA, CON + phase 1(0.6% n-3CFA), phase 2(0.4% n-3CFA), phase 3(0.2% n-3CFA); 4) 0.9CFA, CON + phase 1(0.9% n-3CFA), phase 2(0.6% n-3CFA), phase 3 (0.3% n-3CFA). Each treatment had 10 replicates with 5 pigs (three gilts and two barrows) per replicate. The data were analyzed using the GLM procedure of SAS as a randomized complete block design. Pen served as the experimental unit. Linear, quadratic and cubic polynomial contrasts were used to examine effect of dietary treatment with coated n-3FA in the basal diet. Variability in the data was expressed as the standard error of means and P< 0.05 was considered to statistically significant. Increasing the level of n-3CFA in the diet linearly increased ADG and G/F of pigs (Table 1). Increasing the level of n-3CFA showed a linear increment in the digestibility of DM (83.59, 84.38, 85.13, 85.89 %) whereas nitrogen digestibility (81.79, 82.38, 82.96, 83.64 %) showed a trend (linear effect, p=0.0594) at the end of experiment. The fecal lactobacillus count was increased (7.22, 7.27, 7.33, 7.35 log10cfu/g) with the increase in the supplemental level of n-3CFA (linear effect; p< 0.05). However, there were no differences in the concentration of serum haptoglobin, or fecal E. coli, Clostridium and Salmonella counts despite the increase in n-3CFA levels in the diet. Supplementation of the diet with coated n-3 fatty acids positively affected growth performance and digestibility of dry matter and nitrogen, and enhanced the count of lactobacillus in weaning pigs.

This experiment was performed to examine the hypothesis that blood plasma (BP) with yeast (Saccharomyces cerevisiae) supplement in the diet of weaning pigs could provoke the growth performance, nutrient digestibility, fecal microbial, and reduce harmful gas excretion. A total of one hundred and eighty healthy piglets were taken and assigned (complete random blocks) to three dietary treatments as: Phase 1: Treatment (TRT) 1-6% BP; TRT 2-3% BP + 3% yeast; TRT 3-6% yeast. Phase 2: TRT 1-3%; BP., TRT 2-1.5% BP + 1.5% yeast; TRT 3- 3% yeast. Phase 3: TRT 1- Control (CON) (Basal diet); TRT 2- CON; TRT 3- CON for six- weeks. Each treatment had twelve replicates and five (three gilts and two barrows) pigs per pen. Dietary inclusion of BP with yeast supplementation significantly increased the body weight of piglets during phase 2 (p = 0.003) and phase 3 (p = 0.032). In addition, TRT2 group piglets had a significant improvement in average daily gain at the end of each phase and overall (p = 0.047, 0.025, 0.018 and 0.012, respectively). At phase 3, TRT2 group piglets showed a significant improvement on nutrient digestibility of dry matter (p = 0.012) and nitrogen (p = 0.040). The fecal microbiota of TRT2 group piglets showed a tendency to increase the number of Lactobacillus counts at phase 1 (p = 0.07) and phase 2 (p = 0.06) as well as, a significant improvement at phase 3 (p = 0.021). In addition, TRT2 group piglets had trend to decrease NH3 (p = 0.074) and H2S (p = 0.069) during phase 2, and significantly reduced NH3 (p = 0.038) and H2S (p = 0.046) at phase 3. However, the fecal score of piglets remains unaffected during the entire trial. At the end of phase 1 piglets’ IgG (p = 0.008) was significantly increased with the inclusion of BP with yeast supplementation. Based on the positive effects on body weight, average daily gain, nutrient digestibility, Lactobacillus count, and reduced gas emission, we suggest that dietary supplement with BP and yeast in the diet of weaned piglet could serve as an excellent alternative to antibiotics growth promoters.

In the context of the adoption at the 16th Conference of the Parties in 2010 on the REDD+ mitigation mechanism, it is important to obtain reliable data on the spatiotemporal variation of forest carbon stocks and changes (called Emission Factor, EF). A re-occurring debate in estimating EF for REDD+ is the use of existing field measurement data. We provide an assessment of the use of commercial logging inventory data and ecological data to estimate a conservative EF (REDD+ phase 2) or to report on EF following IPCC Guidance and Guidelines (REDD+ phase 3). The data presented originate from five logging companies dispersed over Gabon, totalling 2,240 plots of 0.3 hectares.We distinguish three Forest Types (FTs) in the dataset based on floristic conditions. Estimated mean aboveground biomass (AGB) in the FTs ranges from 312 to 333 Mg ha−1. A 5% accuracy is reached with the number of plots put in place for the FTs and a low sampling uncertainty obtained (± 10 to 13 Mg ha−1). The data could be used to estimate a conservative EF in REDD+ phase 2 and only partially to report on EF following tier 2 requirements for a phase 3.

Cisplatin Analogues

The introduction of cisplatin in cancer treatment represents an important achievement in the oncologic field. Many types of cancers are now treated with this drug, and in testicular cancer patients major results are reached. Since 1965, other compounds were disovered and among them carboplatin and oxaliplatin are the main Cisplatin analogues showing similar clinical efficacy with a safer toxicity profile. Lipoplatin is a new liposomal cisplatin formulation which seems to have these characteristics. Lipoplatin was shown to be effective in NSCLC both in phase 2 and phase 3 trials, with the same response rate of Cisplatin, a comparable overall survival but less toxicity. A new protocol aiming to elucidate the double capacity of Lipoplatin to act as a chemotherapeutic and angiogenetic agent in triple-negative breast cancer patients is upcoming.
